Description

[0002] According to the patent document with the authorization announcement number "CN217512803U" and the invention name "A clamping device for rivet processing", its specification states: when in use, first place the entire device at the designated working position through the bottom plate, and then fix the fixing plate to the plane where the device is placed through the fixing holes and the fastening bolts, so that the entire device can be fixed. When clamping the rivet, place the rivet on the lower clamping plate in the clamping assembly, and then turn the knob to drive the threaded rod in the vertical rod to rotate. After the threaded rod rotates, the moving block will move up and down along the threaded rod within the range of the moving groove until the two clamping plates can cooperate with each other to clamp the rivet conveniently and stably. At the same time, the anti-slip pads on the two clamping plates can prevent the rivet from sliding when being clamped; but the following defects still exist:

[0003] When the upper and lower clamps clamp the two ends of the rivet, the clamping surface area is small, so the clamping effect of the clamp on the rivet is poor.
