[0024] The inner wall of the moving seat 402 is provided with an inclined through groove, and the inclined through groove is slidably connected with the extrusion column 403. Through the arrangement of the structure, the extrusion column 403 can be stably pushed to move in the vertical direction when the moving seat 402 moves horizontally.
