The rotating shaft 12 and the rotating mechanism 11 cooperate with each other. Under the cooperation of the rotating mechanism 11 and the rotating shaft 12, the threaded rods 10 on both sides can rotate at the same time. The movable shells 9 on both sides can drive the fixed shells 2 to move in opposite directions, so that the device can adjust its position according to the position of the blade body 1, thereby improving the practicality of the device. A fixed plate 13 is provided on one side of the movable shell 9, and a guide block 14 is fixedly connected to the surface of the movable shell 9.
