The stamping base 1 is located on the support plate 3, and the limiting plates 4 press the stamping base 1 onto the support plate 3 through the limiting members.

[0025] The stamping assembly includes a stamping tool head 5 and a buffer. The stamping tool head 5 is connected to the stamping base 1 through the buffer. The stamping tool head 5 and the stamping base 1 are both connected to a handle 6.

[0026] A further optimized solution is provided, in which a groove 7 is provided at the top of the limit plate 4, and the limit member includes a top pressure plate 8 slidably connected in the groove 7. Concave platforms 9 are provided at both ends of the stamping base 1, and the top pressure plate 8 contacts the top of the concave platform 9. A rotating rod 10 is rotatably connected to the top pressure plate 8. The bottom end of the rotating rod 10 extends out of the top pressure plate 8 and is fixedly connected to the threaded rod 11. The threaded rod 11 is threadedly connected to the inner wall of the groove 7, and the top end of the rotating rod 10 extends out of the top pressure plate 8 and is fixedly connected to the first knob 12.
