Abstract

The utility model is a wrench tool with the follower end changeable in size by rotating, two side plates provided with shaft holes are formed at two ends of a pulling lever, respectively, and a containing space is formed between the two side plates, a locating piece is provided at the inner face of each containing space, and an instrument piece is provided for arranging two different sized follower ends, a wedge groove is provided at the recessing position of the peripheral surface of the two ends of each instrument piece corresponding to the locating piece in the containing space, and a punch hole is provided at the corresponding shaft hole position of the side plate, then a shaft lever is provided for threading through the shaft hole and the punch hole corresponding to the pulling lever and the instrument piece, and each of instrument pieces is arranged on the pulling lever for rotary actuating; therefore, the wrench tool can be provided with more different sized actuating ends for selection, and by directly rotating the instrument piece, the actuating end can be changed and the instrument piece with different sizes and various types of actuating ends can be conveniently replaced, thus utilization benefits of convenient using and smooth component replacement can be achieved.

Description

Rotatable conversion different size is made the Wrench of moved end

Technical field

The utility model relates to Wrench.

Background technology

Now, the application of Wrench is quite extensive, its kind is according to using kenel different and a feast for the eyes, as box spanner, open-end wrench and double offset ring spanner etc., with the double offset ring spanner is example, be general the branch hexagonal hole double offset ring spanner and dodecagon hole double offset ring spanner etc. to be arranged, see also shown in Figure 1, it is schematic diagram for dodecagon hole double offset ring spanner, described Wrench is one-body molded at the two ends of tommy bar 10 circular slab face 11 to be arranged, 12, and at each circular slab face 11, offer on 12 one be the dodecagon hole do moved

end

13,14, and make that Wrench has two different sizes do moved

end

13,14 for carrying out dress, tear the operation of bolt tool open; But described Wrench has following disappearance in the use:

Since the tommy bar 10 of Wrench with do moved end the 13, the 14th, one-body molded, so that what Wrench only had two kinds of sizes does moved

end

13,14, because the bolt tool size difference of mounting or dismounting operation, for required in response to using, the dealer must make the Wrench that different sizes such as number brace 6mm, 8mm are done the moved end, and the whole packet size of often same type Wrench is arranged, and promptly has several or tens of more than, so that quite expends cost of manufacture.

Because what Wrench only had two kinds of sizes does moved

end

13,14, it is few that its alternative size is done the moved end, so that the user must often change Wrench, causes quite inconvenience in the use.

Because what Wrench only had two kinds of sizes does moved

end

13,14, if the bolt tool of four kinds of different sizes of user's desire mounting or dismounting promptly must be bought two Wrench, by that analogy, if the size of dismounting the more, the Wrench of purchasing increases relatively, so that quite expends acquisition cost.

Because the volume of Wrench is fixed and Heavy Weight, the whole packet size of often same type Wrench is arranged, and promptly has the many of several or tens of, on placing, quite take up room, when portably using, more form a kind of load, cause the inconvenience that places and carry.

Therefore, how to design a kind of Wrench that provides more different sizes to do the moved end, select for use, and can the convenient rotation transformation required moved end of doing, and reduce cost and the Wrench of being convenient to place, carry, be the target of dealer's research and development for the user.

Summary of the invention

At the deficiencies in the prior art, the purpose of this utility model is: provide a kind of rotatable conversion different size to make the Wrench of moved end, it is to be respectively equipped with an accommodation space at the two ends of tommy bar, has the tool piece that two different size polygonal hole are done the moved end for inserting one, with axostylus axostyle tool piece is installed in the accommodation space, making tool piece can axostylus axostyle be that the axle center rotates start again; So, what described Wrench can have four kinds of different sizes does the moved end for selecting for use, and for direct throw spare, needn't change Wrench in the moved end with doing of using of rapid conversion, reaches the utilization benefit that significantly promotes Wrench.

The purpose of this utility model two is to be: when user's desire uses other size or pattern to make the tool piece of moved end, axostylus axostyle can be taken out, has the tool piece that required size is done the moved end and only must change, needn't change in the lump together with tommy bar, it is good and promote the utilization benefit of Wrench to reach assembly displacement property.

The purpose of this utility model three is to be: a Wrench promptly has the moved end of doing of four kinds of different sizes, makes the whole required Wrench quantity of packet size to reduce, and reaches the utilization benefit that reduces cost of manufacture.

The purpose of this utility model four is to be: a Wrench promptly has the moved end of doing of four kinds of different sizes, purchases the Wrench quantity of putting in order packet size with minimizing, reaches the utilization benefit that reduces acquisition cost.

The purpose of this utility model five is to be: a Wrench promptly has the moved end of doing of four kinds of different sizes, the user can significantly save half usage space, when portably using when placing whole string wrench instrument, also significantly lighten the load, reach the utilization benefit that facility places and carries.

For achieving the above object, the technical solution adopted in the utility model is:

A kind of rotatable conversion different size is made the Wrench of moved end, it is characterized in that: comprising: tommy bar: be to be provided with accommodation space at side; Tool piece: it is installed on the tommy bar, is the moved end of doing with two different sizes, and is installed in axostylus axostyle in the accommodation space of tommy bar, and the position of moved end is done in described relatively tommy bar rotation start with conversion.

Described tommy bar is to be convexly equipped with one group of side plate at side, and forms an accommodation space at two side sheet rooms, and offers corresponding through hole and screw as axis hole on two side plates, and one is assembled in the described axis hole for the axostylus axostyle of bolt.

Accommodation space inner face at tommy bar is provided with keeper and spring, and is concaved with draw-in groove at the corresponding locating piece position of tool piece outer peripheral face.

Each tool piece is to offer perforation for the installing axostylus axostyle.

Described tommy bar is reversing of an angle, and the tool piece of tommy bar side is perpendicular to relative gripping place.

Compared with prior art, adopt the advantage that the utlity model has of technique scheme to be:

1. what described Wrench can have four kinds of different sizes does the moved end for selecting for use, and for direct throw spare, needn't change Wrench in the moved end with doing of using of rapid conversion, reaches the utilization benefit that significantly promotes Wrench.

2. when user's desire uses other size or pattern to make the tool piece of moved end, needn't change in the lump, promote the utilization benefit of Wrench together with tommy bar.

3. reduce and make the whole required Wrench quantity of packet size, reduce cost of manufacture.

4. reduce the Wrench quantity of purchasing whole packet size, reduce acquisition cost.

5. the user can significantly save half usage space when placing whole string wrench instrument, when portably using, also significantly lightens the load.
