Description

Leather pressing handle stapler with nail puller

Technical Field

The utility model relates to a stapler field, concretely relates to take cortex of nail puller to press handle stapler.

Background

The stapler is a machine for fixing paper sheets by staples, and is a common office supply for people. In daily work, the situation is often encountered, and once a thick paper stack is encountered, if the rigidity of the staple is low, the staple is difficult to punch and is clamped in the paper, and then a staple remover is additionally used for removing the broken staple. In order to solve the above problems, chinese patent publication No. CN2049184 discloses a stapler capable of picking up staples, in which a jaw-shaped staple remover is formed at the front end of the head of the stapler. The staple remover is characterized in that a staple groove and the front end of a gland of the staple groove are respectively made into a pair of vertically staggered and opposite teeth which are shaped like a tiger's mouth. When the staple is removed, the tips of the teeth of the jaws bite the lower part of the staple and the staple can be removed by pinching with hands.

The above patents have the disadvantages that: the staple groove and the gland thereof are usually located together without a spring between the staple groove and the base, the traditional stapler spring is arranged between the base and the staple groove, and the proposal has the problem that the staple needs to be taken down due to the need of using the staple groove and the gland as the clamping part when the staple pulling function is used, otherwise, the situation that the staple is pressed out is caused, which causes the repeated binding and staple pulling during the staple pulling process, thus causing the operation inconvenience. Secondly, most of the existing staplers are linear plastic pressing handles which are long and narrow, high in hardness and lack of comfort, and hands and even shoulders can be uncomfortable due to long-time binding.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to overcome prior art not enough, provide a leather pressing handle stapler of area nail puller for solve the problem that needs to take off the staple repeatedly when current stapler uses the nail pulling function, thereby make the operation more convenient.

The purpose of the utility model is realized through the following technical scheme:

the leather pressing handle stapler with the nail puller comprises a pressing cover, a base and a nail groove, wherein the base is provided with a nail seat corresponding to a nail outlet of the nail groove, the pressing cover, the nail groove and the base are sequentially hinged from top to bottom to form the stapler, the front end of the base is provided with a lower extension part, and the lower extension part is provided with a lower nail pulling tooth with an upward pointed end;

the front end of the nail groove is provided with an upper extension part, and the upper extension part is provided with upper nail pulling teeth with downward tips corresponding to the positions of the lower nail pulling teeth;

the nail groove is provided with a baffle plate at each of two sides of the rear end above the nail outlet, the two sides of the upper extension part are provided with a sliding groove respectively, a sliding cover plate is inserted into the two sliding grooves, and the sliding cover plate slides left and right to cover the upper part of the nail outlet;

the nail seat is movably installed on the base through a rotating shaft, the base is provided with a groove, and the rotating shaft is rotated to hide the nail seat in the groove.

In order to overcome the problem that the staple needs to be withdrawn repeatedly when the stapler is used as a staple remover in the prior art, the scheme utilizes the 'clamping part' formed by the spring between the staple groove and the base, the staple-withdrawing teeth are respectively arranged at the front end of the staple groove and the front end of the base to form the staple remover, and in order to avoid the staple withdrawing phenomenon, the scheme is provided with the sliding cover plate above the staple outlet of the staple groove, only the sliding cover plate is needed to cover the staple outlet when the staple is required to be taken, so that the extrusion part of the gland can not enter the staple groove, thereby ensuring that the staple can not be extruded out of the staple, and because the scheme is an upper extension part formed by extending in the front of the traditional staple groove, the gland does not need to be overturned when the sliding cover plate is pushed, thereby.

Furthermore, the tip of the upper nail lifting tooth does not exceed the contour line of the bottom of the nail groove.

Further, the tip of the lower nail lifting tooth does not exceed the plane of the nail seat.

The goal of the design is to ensure that the pointed end does not pinch the target binding during stapling.

Further, the nail seat is rectangular, and the shape of the groove is the shape of the nail seat after rotating by 90 degrees; the nail seat is characterized in that the nail seat is fixed through the embedded groove and then still exceeds the plane of the base by a certain height, so that the tip of the lower nail-lifting tooth cannot puncture a book.

Further, a cavity corresponding to the groove is formed in the lower portion of the base, the rotating shaft penetrates through the base and is located in the cavity, a knob is fixed to the tail end of the rotating shaft, and a return spring is sleeved on the rotating shaft between the knob and the base.

Further, the length of pivot satisfies when the nail seat is located the recess, the knob still does not stretch out the base bottom contour line yet, and this design is the roughness of guaranteeing the base.

Furthermore, the tail end of the sliding cover plate is provided with a limiting part, and the sliding cover plate is prevented from falling off due to the design.

Furthermore, the top of the front end of the gland is designed into an arc shape, the surface of the gland is covered with a PU (polyurethane) skin, and the PU skin (microfiber skin) is arranged to reduce fatigue, so that the gland is more comfortable to use.

The utility model has the advantages that: compared with the prior art, this scheme utilizes the elastic construction between nail groove and the base, as the main part of nail puller, makes it can be closed by hand, loosens autosegregation, then sets up the baffle on going out the nail mouth (nail groove both sides) and is used for supporting sliding cover plate for on the extrusion portion direct action on sliding cover plate on the nail pulling in-process gland, avoided the extrusion to the staple, consequently the nail pulling in-process need not to move back the nail and can operate.
