Then, the rear side of the thickened template corresponds to the left and right sides of the first clamping block and the second clamping block to connect the stamping plate for the stamping of the stamping head. When pressurizing, the pressure on the thickened template is increased, so that the stamping effect of the thickened template is closer to the stamping effect of the first clamping block and the second clamping block. At the same time, the inner diameter of the second stamping cavity is smaller than the inner diameter of the first stamping cavity. Therefore, when the thickened template is stamped, the pressure will be less than the pressure directly applied by the stamping head on the first clamping block, so that the final pressed cable nose effect is better by reducing the inner diameter. By arranging a plug-in block and a clamping block on the inner side of the thickened template, it is used to better fix the thickened template on the first clamping block and the second clamping block when it is plugged in.
