Abstract
The utility model discloses an aviation is cut in the scissors field, including two articulated shear blades of each other and two handles that link to each other with corresponding shear blade respectively, the handle is articulated mutually through the side articulated shaft with the afterbody of corresponding shear blade, the head of two handles through middle articulated shaft mutually articulated in the middle of and the periphery cover of articulated shaft be equipped with the torsional spring, two torsion arm of torsional spring elasticity respectively contradict on corresponding handle, still articulated on the side articulated shaft of one of them handle have the locking to detain, the locking is detained including body and the crotch that holds another handle upside articulated shaft that is located the body head, the outside that the locking was detained is equipped with the outer convex part that can supply the thumb to promote. The periphery that the corresponding side articulated shaft tip of body head was detained to the locking sets up to the inclined plane. Handle periphery cover is equipped with the antiskid cover. The utility model discloses can one -hand operation, freely cutting out, switching over between three kinds of states of locking and unblock, use nimble, not the time spent lock the shear blade, portable, safer.
Description
Technical field
The utility model belongs to scissors field, is specifically related to a kind of aviation shears.
Background technology
Aviation shears can be used for the sheet metals such as cutting copper sheet, iron plate, has higher shear ability.In prior art, there is a kind of convenient aviation shears, its publication number: CN202964691U; Publication date: 2013.06.05; Application number: 201220736260.1; The applying date: 2012.12.26, its structure comprises scissors bit and shear shank, and described shear shank comprises left shear shank and right shear shank, and described right shear shank is provided with projection, and the rear end of described left shear shank is provided with left handle, and the rear end of described right shear shank is provided with right handle.Its weak point is: lack locking device between left shear shank and right shear shank, and when scissors bit is in open configuration, blade easily scratches people, and safe not, when being placed in bag by aviation shears, scissors bit is mobilizable, carries inconvenience.
Utility model content
The purpose of this utility model is to provide a kind of aviation shears, makes it easy to carry, safer, can carry out one-handed performance, uses flexibly.
The purpose of this utility model is achieved in that a kind of aviation shears, comprise two mutually hinged shear blades and two handles be connected with corresponding shear blade respectively, the afterbody of described handle and corresponding shear blade is mutually hinged by side jointed shaft, the head of two handles is mutually hinged and the periphery of middle jointed shaft is arranged with torsion spring by middle jointed shaft, two torque arm difference elasticity of torsion spring are conflicted on corresponding handle, the side jointed shaft of one of them handle is also hinged with locking button, described locking button comprises body and is positioned at the crotch holding jointed shaft on the upside of another handle of body head, the outside of described locking button is provided with the male part that can promote for thumb.
The utility model is not when locking, and two handles outwards get out by torsion spring, and two shear blades open, and now one hand is held two handles and constantly extruded and sheet metal can be cut off; When complete cut out operation need to be locked time, first inwardly extruding handle makes shear blade close up, then promotes the male part of tight locking button until side jointed shaft hooks by crotch with thumb, and aviation shears just completes locking.Compared with prior art, the beneficial effects of the utility model are: can carry out cutting out operation by one hand, and aviation shears can singlehandedly not locked by the used time yet, and use flexibly, easy to operate, shear blade can not locked by the used time, is easy to carry, safer.
As further improvement of the utility model, the periphery of described locking button body head respective side jointed shaft end is set to inclined plane.When needing to unlock, one hand holds two handles, firmly inwardly extruding, and side jointed shaft can be pushed open along the inclined plane of tight locking button head, and side jointed shaft decontroled by crotch, and unblock completes, and can proceed again to cut out operation.
As further improvement of the utility model, described handle periphery is arranged with Anti-slip cover.Anti-slip cover increases the frictional force between hand and handle, more convenient to use.
As further improvement of the utility model, the afterbody of another handle described is provided with the suppending hole that can pass for suspension strop.The not used time, suspension strop passed suppending hole and hangs on body of wall hook, being convenient to deposit, not taking up room.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation after the utility model locking.
Wherein, 1 shear blade, 2 handles, 3 side jointed shafts, 4 middle jointed shafts, 5 torsion springs, 6 locking buttons, 6a crotch, 6b male part, 7 Anti-slip covers, 8 suppending holes.
Detailed description of the invention
As shown in Figure 1-2, for a kind of aviation shears of the present utility model, comprise two mutually hinged shear blades 1 and two handles 2 be connected with corresponding shear blade 1 respectively, handle 2 is mutually hinged by side jointed shaft 3 with the afterbody of corresponding shear blade 1, the head of two handles 2 is mutually hinged and the periphery of middle jointed shaft 4 is arranged with torsion spring 5 by middle jointed shaft 4, two torque arm difference elasticity of torsion spring 5 are conflicted on corresponding handle 2, the side jointed shaft 3 of one of them handle 2 is also hinged with locking button 6, locking button 6 comprises body and is positioned at the crotch 6a holding jointed shaft 3 on the upside of another handle 2 of body head, the outside of locking button 6 is provided with the male part 6b that can promote for thumb.The periphery of locking button 6 body head respective side jointed shaft 3 end is set to inclined plane.Handle 2 periphery is arranged with Anti-slip cover 7.The afterbody of another handle 2 described is provided with the suppending hole 8 that can pass for suspension strop.
When not locking, two handles 2 outwards get out by torsion spring 5, and two shear blades 1 open, and now one hand is held two handles 2 and constantly extruded and sheet metal can be cut off; When complete cut out operation need to be locked time, first extrude handle 2 and shear blade 1 is closed up, then promote the male part 6b of tight locking button 6 until side jointed shaft 3 hooks by crotch 6a with thumb, aviation shears just completes locking; During unblock, one hand holds two handles 2, and continue firmly inwardly extruding, side jointed shaft 3 can be pushed open along the inclined plane of tight locking button 6 head, and crotch 6a decontrols side jointed shaft 3, and unblock completes, and can proceed again to cut out operation.This device can one-handed performance, and freely switch cutting out, lock and unlock between three kinds of states, use flexibly, shear blade is not locked by the used time, is easy to carry, safer.
The utility model is not limited to above-described embodiment; on the basis of technical scheme disclosed in the utility model; those skilled in the art is according to disclosed technology contents; do not need performing creative labour just can make some to some technical characteristics wherein to replace and distortion, these are replaced and are out of shape all in protection domain of the present utility model.
