[0020] The rotating clamping mechanism 3 includes a rotating shaft 301 rotatably connected to the side plate 2, the rotating shaft 301 is fixedly connected to the rotating ring 302, the rotating ring 302 is threadedly connected to the threaded rod 303, two threaded rods 303 are provided, and the two threaded rods 303 are symmetrically arranged on the rotating ring 302, the threaded rod 303 is fixedly connected to the clamping handle 304, and one end of the threaded rod 303 away from the clamping handle 304 is rotatably connected to the clamping plate 305. The positioning mechanism 4 includes a positioning plate 401 fixed to the rotating shaft 301, the positioning plate 401 is fixedly connected to the spring 402, the spring 402 is fixedly connected to the spring fixing plate 403, the spring fixing plate 403 is fixedly connected to the positioning rod 404, the positioning rod 404 passes through the positioning plate 401 and is slidably connected to the positioning plate 401, and a plurality of positioning holes 405 are provided on the side plate 2.

[0021] Specifically, the watch case is placed between the two clamping plates 305, and the clamping handle 304 is rotated to drive the threaded rod 303 to rotate, and then drive the clamping plate 305 to feed, so as to complete the clamping and fixing of the watch case. If the watch case needs to be rotated and displaced, the positioning plate 401 is rotated, and then the rotating shaft 301 is rotated, thereby driving the rotating ring 302 to rotate, so that the watch case rotates. When it reaches the specified angle, the positioning rod 404 is inserted into the positioning hole 405.

Under the action of gravity, the mounting plate 6 and the impact head 10 will drop to achieve impact. At the same time, the first pressure sensor 9 can detect the pressure during the impact.
