The top of the inner rod of the telescopic rod 502 is fixedly connected to a limiting plate 504. A spring 503 is installed between the limiting plate 504 and the base 1, and the top of the limiting plate 504 abuts against the quick-changing component 4.

[0025] Among them, the quick-change assembly 4 includes a main cover plate 401, the top of the main cover plate 401 is fixedly connected to the end of the telescopic rod of the electric cylinder 3, a slot 410 is opened in the middle of the main cover plate 401, a printed plate 402 is inserted in the slot 410, the slot 410 and the printed plate 402 are symmetrically provided with a socket 1 403 and a socket 3 408, and the top of the limit plate 504 and the bottom of the main cover plate 401 are abutted when in use. By setting up a quick-change component 4, and symmetrically opening a socket 1 403 and a socket 3 408 at one end of the main cover 401 and the printing plate 402, and the positions of the two holes overlap each other, it is convenient for subsequent components to fix the printing plate 402, so that the printing plate 402 can be accurately fixed on the main cover 401, thereby greatly improving the printing accuracy of the printing plate 402 and reducing material waste. At the same time, by abutting the limit plate 504 with the main cover 401 during use, the limit plate 504 can elastically limit the main cover 401 under the action of the spring 2 503, thereby buffering the downward pressure of the electric cylinder 3 pushing the main cover 401, thereby greatly improving the printing quality.

[0026] Among them, a plug 405 is inserted into the socket 1 403 and the socket 3 408, and a pull ring 407 is fixedly connected to the top of the plug 405. By fixing the pull ring 407 at one end of the plug 405 and inserting the plug 405 into the socket 1 403 and the socket 3 408, the printing plate 402 can be locked and unlocked by pulling the pull ring 407.
