Description
Technical field
The utility model relates to the hand tools used in mechanical hardware & tools field, more particularly, is a kind of back-up ring dismounting pincers.
Background technology
At present, when carrying out Automatic manual transmission, needing to use curved pawl retainer pliers and straight pawl retainer pliers respectively to traditional shaft block ring and hole back-up ring, also having and can jointly use one retainer pliers is carried out dismounting to axle hole back-up ring simultaneously.A kind of in Chinese patent literature disclosed " axis hole shares retainer pliers ", its publication number is " axis hole shares retainer pliers " in this technical scheme of CN203636768U, adopt reversing ratchet wrench rotate left-right rotary screw rod make left and right spin nut simultaneously away from or close to pitch, jaw is opened or shrinks, chela and caliper split design in addition, a caliper installs different chelas, the installation and removal of all axles, hole back-up ring can be completed, both saving was beneficial to, time saving and energy saving again, and safe and reliable.But due to this " axis hole shares retainer pliers " in use, when chela need conversion time, need the defect changing other chelas after being unloaded by original chela again.
Summary of the invention
The utility model to be devoted to solve in prior art when chela needs conversion, needs the defect changing other chelas after being unloaded by original chela again.Aim to provide one need not change other chelas can the straight pawl of Direct Transform or curved pawl, a kind of back-up ring dismounting pincers simple to operate.
In order to solve the technical problem of above-mentioned existence, the utility model adopts following technical proposals: a kind of back-up ring dismounting pincers, comprise caliper, chela and clamp handle composition, described caliper one end is provided with U-lag, the bottom of U-lag is provided with tightening screw, in tightening screw, adaptation has holding screw, one end of described chela is provided with straight pawl, the other end is provided with curved pawl, the inner of described straight pawl and curved pawl is provided with square bar, the centre position of square bar is provided with the locating hole corresponding with tightening screw, pressing plate is provided with above described chela, one end of pressing plate is provided with open slot, centre is provided with the screw hole that is corresponding and holding screw adaptation with tightening screw, just can accomplish after only original chela need being turned around that need not change other chelas gets final product the straight pawl of Direct Transform or curved pawl, operate quite simple, it also avoid traditional retainer pliers owing to causing caliper to damage together after chela damage, a large amount of expense can be saved.
As preferably, described clamp handle is located at the caliper other end reverse with chela, is easy to open or closes up chela.
As preferably, described clamp handle is provided with stage clip between caliper, chela can be made to be in open mode all the time in a free state, directly can certainly use without stage clip.
Owing to adopting technique scheme, the beneficial effect of a kind of back-up ring dismounting pincers that the utility model provides is: 1. can the straight pawl of Direct Transform or curved pawl; 2. simple to operate.
