Abstract
A kind of split pin special vice, its structure is: consist of pinned connection holder brank handle and cutting edge clamp handle, the front end of holder brank handle is provided with the block of vertical section rectangle, and the front end of cutting edge clamp handle is provided with the cutting edge that vertical section is right-angled trapezium, and the angle in the relative below block direction of cutting edge is acute angle.The utility model adopts said structure; by being provided with block on holder brank handle; cutting edge clamp handle is provided with cutting edge; solve the locking treatment effect existed in prior art bad; quality can not get ensureing and ineffective technical problem, and the utility model adopts simple structure, not only can protect nut quality during bolt-lock; avoid scratching, and significant increase operating efficiency.
Description
Technical field
The utility model relates to a kind of pliers, especially a kind of split pin special vice.
Background technology
At present, bolt connection is widely used, because this kind of connected mode is simple and quick, reliability is high, can significant increase cylinder block strength, and bolt connection amount is large, distribution is wide, after particularly the semiclosed region of aircraft needs bolt to install, need according to designing requirement or adopt the conventional manual method such as screwdriver, combination pliers in particular importance junction, locking process is done to it.Although conventional manual method reaches screw retention effect on necessarily proclaiming oneself emperor, easily scratching nut when making, being affected by human factors comparatively large, work quality can not get ensureing, and it is many to make quantity, reduces operating efficiency.
Summary of the invention
In order to solve the problems of the technologies described above, the utility model provides a kind of split pin special vice.By being provided with block on holder brank handle, cutting edge clamp handle is provided with cutting edge, more enough to greatest extent bending and fastening is implemented to split pin, solve exist in prior art to loosen treatment effect bad, quality can not get ensureing and ineffective technical problem.
To achieve these goals, the technical solution used in the present invention is: a kind of split pin special vice, it is characterized in that: be made up of by pinned connection holder brank handle and cutting edge clamp handle, the front end of holder brank handle is provided with the block of vertical section rectangle, the front end of cutting edge clamp handle is provided with the cutting edge that vertical section is right-angled trapezium, and the angle in the relative below block direction of cutting edge is acute angle.
Described holder brank handle and bearing pin are interference fit, and cutting edge clamp handle and bearing pin are sliding fit.
The beneficial effects of the utility model are: the utility model adopts said structure; by passing through to be provided with block on holder brank handle; cutting edge clamp handle is provided with cutting edge; solve the locking treatment effect existed in prior art bad; quality can not get ensureing and ineffective technical problem, and the utility model adopts simple structure, not only can protect nut quality during bolt-lock; avoid scratching, and significant increase operating efficiency.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in detail.
A kind of split pin special vice as Figure 1-3, it is characterized in that: connected to form by bearing pin 3 by holder brank handle 1 and cutting edge clamp handle 2, the front end of holder brank handle 1 is provided with the block 4 of vertical section rectangle, block 4 with as shown in Figure 4 make split pin nut 6 edge fit, for limiting by the position of making nut 6, during to ensure that split pin special vice uses firmly and stable.The front end of cutting edge clamp handle 2 is provided with the cutting edge 5 that vertical section is right-angled trapezium, the angle in relative below block 4 direction of cutting edge 5 is acute angle, sharp edge during work on cutting edge 5 is implemented the bending of split pin 7 and fastening, thus realizes the locking of bolt, reaches the effect of insurance.In order to ensure that operation is formed, cutting edge clamp handle 2 and bearing pin 3 are sliding fit, and holder brank handle 1 is interference fit with bearing pin, ensure that holder brank handle and cutting edge clamp handle assemble rear folding freely.
During work, first adopt and determine torque wrench nut 6 is as shown in Figure 4 tightened, after adjusting cotter-pin hold, insertion opening pin 7, aims at the nut 6 that will make by split pin special vice jaw, and the edge block 4 on cutting edge clamp handle 1 head and institute being made the nut 6 of split pin fit firm after, counter blade brank handle 2 is afterburning again, cutting edge 5 pairs of split pins 7 in cutting edge clamp handle 2 are bent, and fastens on nut 6, thus realize the function of bolt-lock.
Apply this split pin special vice; not only can protect the quality of nut during bolt-lock; avoid scratching; and greatly improve the efficiency of work; it is simple, convenient to use; the phenomenon of doing over again avoiding secondary to make causing, being applicable to semiclosed in transporation by plane and not opening wide district, all playing great role to improving product quality and production efficiency.
