[0017] Reference Figure 1-2 , wherein the driving assembly 5 includes a connecting block 51 rotatably connected to the surface of the fixed plate 2, a rotating shaft 52 is rotatably connected to the connecting block 51, one end of the rotating shaft 52 is fixedly connected to the output end of the driving device, a threaded sleeve 53 is rotatably connected to the rotating seat 4, and a first external thread 54 adapted to the threaded sleeve 53 is provided at one end of the rotating shaft 52 away from the connecting block 51, and the rotating shaft 52 is located inside the threaded sleeve 53;

[0018] Through the above-mentioned structural arrangement, when the driving device drives the rotating shaft 52 to rotate forward, the first external thread 54 of the rotating shaft 52 will produce relative movement with the internal thread of the threaded sleeve 53, so that the threaded sleeve 53 moves in a direction close to the rotating shaft 52, thereby clamping the rod material. Conversely, when the rotating shaft 52 is reversed, the rod material is loosened.
