Pressing pliers with trapezoidal teeth

According to the pressing pliers with the trapezoidal teeth, the trapezoidal teeth are arranged on the pliers clamping ring, so that the pressure of the pressing pliers on a stainless steel sleeve can be dispersed and released, uniform deformation of the stainless steel sleeve is facilitated, and the generation of convex ribs is inhibited: on one hand, the closed line of the trapezoidal teeth is relatively long and is provided with a concave-convex structure, a transverse line and an oblique line, so that the stainless steel sleeve deforms due to radial stress; axial stress deformation is generated, deformation is dispersed, accumulation deformation is released, and it is ensured that the stainless steel sleeve deforms uniformly; and on the other hand, the corresponding trapezoidal teeth of the first half snap ring and the second half snap ring are in conical surface occlusion, so that automatic correction along the axial direction of the clamp snap ring is facilitated, and axial dislocation between the first
