Clamping block, clamping set and traction mechanism

The utility model provides a clamping block, a clamping group and a traction mechanism, which are used for solving the problem of non-uniform stress of a clamped profile during pultrusion production of the profile in the prior art. The utility model provides a clamping block, a clamping group and a traction mechanism, the clamping block comprises a back plate, the lower end face of the back plate is provided with a clamping groove, and the clamping groove penetrates through the front side wall and the rear side wall of the back plate; and the clamping colloid is installed on the back plate, the clamping colloid is attached to the inner wall of the clamping groove, and the thickness of the clamping colloid in the area of the clamping groove is equal. According to the profile clamping device, the clamping groove is formed, the clamping colloid with the same thickness is arranged in the area of the clamping groove, therefore, the profile can be clamped, and meanwhile, during clamping, due to the fact that the cl
