[0029] A sliding groove is provided inside the fixing plate 3 , and a bolt 13 is threadedly connected to the inside of the sliding plate 4 and passes through and extends into the sliding groove.
[0030] When the bolt 13 is tightened, the bolt 13 will press against the inside of the chute, and the slide plate 4 will move upward under the action of the thread, and the slide plate 4 will be fixed inside the chute by friction.
[0031] The outer side of the connecting rod 10 is provided with a thread, and the outer side of the connecting rod 10 is fixedly connected to a sleeve 15 that is rotatably connected to the sliding block 14 .
[0032] By rotating the sleeve 15 , the sliding block 14 will move upward or downward under the drive of the sleeve 15 , so that the fixed block 11 is opened or closed.
