A fixed block 2 504 is arranged on the side of the fixed block 1 501 away from the auxiliary desktop 2, and the fixed block 2 504 penetrates and is fixedly connected to the middle of the main desktop 1. A side of the fixed block 2 504 close to the wedge block 502 penetrates and is slidably connected with evenly distributed baffles 503. The rotating rod 8 is rotatably connected to one side of the fixed block 2 504. Both sides of the front side of the rotating disk 12 are rotatably connected to the rotating shaft 1 9. One side of the rotating shaft 9 is fixedly connected to the connecting rod 7. One end of the connecting rod 7 is fixedly connected to the rotating shaft 2 13, and the rear end of the rotating shaft 2 13 is rotatably connected to the front side of the fixed block 1 501. With the cooperation of the rotating shaft 1 9, the connecting rod 7 and the rotating shaft 2 13, the fixed block 1 501 moves closer to the turntable 12, so that the wedge block 502 is separated from the blocking piece 503, and the limit is released.
