Description

Combination wrench

Technical field

The utility model relates to a kind of mechanical dismantling device, relates in particular to a kind of combination wrench.

Background technology

Extracting tool commonly used at present comprises spanner, pipe wrench, wherein shfting wrench is made up of regulating wheel, handle, spanner movable part, pipe wrench is fixedly to be formed by eave tile, regulating wheel, handle, spring leaf and regulating wheel, when the larger-diameter workpiece of dismounting, regulating wheel will rotate a lot of number of turns, governing speed is slow, efficient is low, and spanner, the pipe wrench scope of application are little, shfting wrench can only the common hex bolts of dismounting, pipe wrench can only the dismounting pipe fitting, function of use is single separately, can not be general or alternative mutually.

The utility model content

The purpose of this utility model provides the combination wrench that a kind of governing speed is fast, efficient is high, the scope of application is wide.

The utility model is realized above-mentioned purpose by the following technical solutions: a kind of combination wrench, comprise caliper, eave tile, adjusting device, on caliper, be set with sliding box, eave tile is hinged on the sliding box upper end and at the eave tile rear portion return spring is installed, the caliper upper side is provided with tooth bar, and adjusting device is positioned at sliding box and is installed in the sliding box bottom.

Adjusting device is regulated ratchet and is positioned at sliding box for regulating ratchet, and the ratchet middle part is hinged on the sliding box bottom.

Fixedly on the sliding box, the other end withstands in the locating slot at eave tile rear portion return spring for the reed of bending a, end, is set with torsion spring regulating on the ratchet jointed shaft, and torsion spring one end lever arm is fixed on the sliding box, and other end lever arm withstands on the rear lower of adjusting ratchet.

Another kind of technical scheme is that return spring is the reed of bending, and fixedly on the sliding box, an end withstands in the locating slot at eave tile rear portion at the middle part, and the other end withstands in the locating slot of adjusting ratchet front end.

Both sides, caliper top all are provided with tooth bar.

Described tooth bar is the helical rack that teeth directional has a down dip.

Eave tile inner side edge angle is 60 degree angles, angle arc-shaped transition.

The utility model uses tooth bar and ratchet to replace the screw thread feeding, regulating jaw size is realized by return spring two parts of adjusting device and eave tile, under the roof pressure of torsion spring or return spring, regulate in the teeth groove of ratchet front end embedding tooth bar, the opposite direction of caliper of being automatically locked is slided, when needs are adjusted jaw size, press down and regulate the ratchet rear portion, ratchet rotates and makes front end break away from the teeth groove of tooth bar, and caliper is free to slide in sliding box, but the rapid adjustment jaw size, than the fast 10-20 of existing threaded adjusting doubly, the adjusting Panasonic's ratchet that finishes, torsion spring or return spring effect make ratchet embed teeth groove, locked caliper reverse slide.Eave tile is hinged on the sliding box upper end, eave tile rotates around pin joint, after being stuck on the workpiece, eave tile automatically resets under the effect of return spring during revolution, be adjacent to workpiece, return spring also plays the fine setting effect of jaw simultaneously, when eave tile need hang up workpiece, eave tile can suitably be adjusted jaw size and hang up workpiece around the pin joint certain angle that rotates backward.The eave tile inboard is designed to 60 degree angles, 3 of formation are stressed piece-holder on inboard 2 points of eave tile, the caliper when dismounting, jaw and big with the workpiece contact area, stressed good, the spanner reinforcing can form unidirectional loading and make spanner chucking workpiece during work, oppositely unclamps, and does not need to be installed repeatedly, once can lock or dismantle operation, make work efficiency improve several times.Can directly change eave tile and needn't change instrument according to the workpiece size in addition, save the instrument acquisition expenses.In the caliper both sides tooth bar is set all, can arbitrarily change the tooth bar that caliper is meshed with ratchet like this, if a side tooth bar is damaged, the caliper direction that swaps round uses the tooth bar of an other side can continue to use, and the interlock teeth of caliper upper end have more a part on one side, and conversion caliper direction can both tighten the workpiece of different sizes.The utility model is little for the operating space, and the dismounting of the workpiece that can't directly observe has its special advantages, the also dismantled and assembled pipe fitting of both dismantled and assembled hex bolts.

Description of drawings

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the structural representation of another kind of embodiment of the present utility model.

The specific embodiment

As shown in Figure 1, combination wrench comprises caliper 7, eave tile 1, on caliper 7, be set with sliding box 3, eave tile 1 is hinged on sliding box 3 upper ends and at eave tile 1 rear portion return spring 2 is installed, return spring 2 is a reed, return spring 2 bends to eave tile, one end is fixedly on the sliding box 3, the other end withstands in the locating slot 11 at eave tile 1 rear portion, caliper 7 top dual-sides are provided with tooth bar 4, and tooth bar 4 is helical racks that teeth directional has a down dip, and regulate the bottom that ratchet 5 is located in the sliding box 3 and is hinged on sliding box 3, torsion spring 6 is sleeved on to be regulated on ratchet 5 jointed shafts, torsion spring 6 one end lever arms are fixed on the sliding box 3, and other end lever arm withstands on the rear lower of regulating ratchet 5, and caliper 7 tops and eave tile 1 are formed jaw, caliper 7 tops are provided with teeth 9, eave tile 1 inboard also is provided with teeth 10, and the teeth 9 at caliper 7 tops are provided with and exceed the caliper side, help clamping work pieces, eave tile 1 inner side edge angle a is 60 degree, angle arc-shaped transition.

As shown in Figure 2, be the another kind of embodiment of the utility model, return spring 2 is the reed of bending, fixedly on the sliding box 3, an end withstands in the locating slot 11 at eave tile 1 rear portion at return spring 2 middle parts, and the other end withstands in the locating slot 8 of regulating ratchet 5 front ends, substituted the torsion spring of first kind of embodiment at this return spring 2, played to suppress and regulated the effect that ratchet 5 embeds tooth bar 4 teeth groove, all the other structures are consistent with first kind of embodiment, do not repeat them here.
