The pressing-in head 22 is fixedly arranged at the center of the pressing-in plate 23, and the center of the pressing-in head 22 is hollow.

[0021] Please refer to Figure 3 , the rotating assembly 3 includes a disc 31, a indexing cylinder 32, a limit block 33, a rotating arm 34, a pawl 35 and a ratchet 36. Four workstations 311 are evenly arranged on the surface of the disc 31. The distances from the four workstations 311 to the center of the disc 31 are the same. The workstations 311 are provided with positioning posts and fixing seats. The fixing seats are fixedly arranged on the disc 31, and the positioning posts are fixedly arranged at the centers of the fixing seats. The disc 31 is rotatably limited on the frame 1 through a bearing seat 37. Each time the disc 31 rotates, one of the workstations 311 stays directly below the pressing-in head 22, and the other workstations 311 are arranged outside the vertical projection range of the pressing-in assembly 2 on the frame 1, which is convenient for workers to place accessories on the other workstations 311 and reduces the operation risk.

[0022] The bearing housing 37 is rotationally limited on the frame 1. A ratchet wheel 36 is fixedly arranged at the center of the bearing housing 37. The ratchet wheel 36 is fixedly connected to the disc 31. Four ratchet teeth are evenly arranged on the outer wall of the ratchet wheel 36. A limit block 33 is arranged on one side of the ratchet wheel 36. One end of the limit block 33 is rotatably connected to the frame 1, and the other end abuts against the outer wall of the ratchet wheel 36. A retaining spring 38 is arranged between the limit block 33 and the frame 1. One end of the retaining spring 38 is rotatably connected to the frame 1, and the other end is connected to the limit block 33. One end of the limit block 33 is in shape fit with the ratchet teeth.
