Gear engagement transmitting power on idle wheel, binding clip clamp system, the shell and upper cover plate are that steel plate is integrally stamped to form；It is described
Shell upper limb one encloses outward flanging, is equipped with screw hole at flange and upper cover plate is fastened together by screw；The lower righting is total
At being fixed on shell, upper righting assembly is fixed on upper cover plate；The binding clip clamp system is located in shell and upper cover plate
It can be rotated between upper righting assembly and lower righting assembly；Connecting plate is fixed with upper righting assembly in the binding clip braking reversing mechanism
Together, braking bolt passes through tripping spring and brake disc is fixed on upper cover plate；The two of the axle of carrier pulley and double crosslinking gear shaft
End is respectively equipped with axial step and screw thread, and the axial step at both ends is withstood between upper cover plate and shell respectively, the screw thread point at both ends
Hole on upper cover plate and shell and nut Chuan Guo not be passed through fasten.
Local enhancement platform is equipped on the shell described in a kind of novel main pincers of above-mentioned small dimension Power Tong and upper cover plate
Rank.
The shell described in a kind of novel main pincers of above-mentioned small dimension Power Tong uses plate for the plate of deep-draw.
It is further mitigation weight, the shell and upper cover plate in a kind of novel main pincers of above-mentioned small dimension Power Tong
For aluminum alloy plate materials.
Shell and top panel use cold punching pressing formation in the utility model, and steel plate generates plastic deformation hardening through cold punching, with
And the punching structure using local enhancement, steel plate thickness rate routine steel-casting wall thickness reduce 1/3, integral strength increases instead
20% or more.Wherein axle of carrier pulley and double crosslinking gear shaft to main pincers shell, back-up tong head circle and cylinder seat and fulcrum bearing to back-up tong shell all
There are support and booster action.In stamping process, shape, opening, most of hole can stamp out, and following process amount is very
Small, precision and size also can guarantee that unification with accurately, is also convenient for producing in enormous quantities.Therefore it is dynamic to meet small dimension for the utility model
Power pincers lightweight, low energy consumption problem, not only environmental protection again alleviate weight, reduce cost, and intensity increases instead, society imitate
Beneficial huge, economic benefits.
