Description

Water pump pliers

Technical field

The utility model relates to a kind of tongers, and in particular to one kind can the workpiece such as elastic water pipe, gas pipe or bolt, can mention Height bears the water pump pliers of torque.

Background technique

Prior art is just as " one-handed performance voluntarily clamps TaiWan, China patent the 088115365th (certificate number 429204) Pliers " shown in as, still, at least following missing of case before the invention:

One, its ratchet wheel and door bolt tooth system belong to general gear structure, it is possible to and the number of teeth of engagement is fairly limited, so When bearing the torque of elastic workpiece, the problems in stress collection is had.

Two, it holds described in first point, for the ratchet wheel when engagement door bolt tooth system bears torque, which has rotation to skid it It is excellent, in this way, will cause that plier extends out and can not really effectively elastic workpiece the problem of.

Three, secondly the contact area of clamp handle infall can not effectively increase, so when bearing the torque of elastic workpiece, meeting There is the problems in stress collection.

This creator has the shortcomings that above-mentioned in view of the preceding case, and through multi-party experimental design, successfully creation can be solved thoroughly eventually Certainly the utility model of the preceding case problem.
