[0026] Furthermore, one side of the washer supporting member 3 is fixedly connected to the washer track 2 by a first bolt 304 .

[0027] Furthermore, both front and rear ends of the upper end of the washer track 2 are fixedly connected to the limiting posts 203 , and both front and rear ends of one side of the pressing piece 4 are fixedly connected to the wing plates 403 , and a limiting circular hole 404 is provided in the middle of the wing plates 403 .

[0028] Furthermore, the pressing part 4 is connected to the washer rail 2 through a limiting circular hole 404 via a limiting column 203, a circular limiting plate 204 is fixedly connected to the upper end of the limiting column 203, and the upper end of the screw rod passes through the third screw rod socket 402. When the screw rotates, the front and rear end surfaces of the upper end of the washer are pressed down through the pressing plate 401, so that the upper end of the washer moves to the lower end of the screw rod under the action of the downward pressure to achieve a stable combination.

[0029] Furthermore, a spring 205 is provided between the lower end of the circular limiting piece 204 and the upper end of the wing plate 403 , so that the pressing piece 4 can move slightly on the washer track 2 .

When the washer moves inside the washer limit groove 201, the lower end of the rectangular limit member 5 is inserted into the washer limit groove 201 to limit the movement of the washer, preventing the washer from escaping from the washer track 2 from the upper end of the washer limit groove 201. When the screw turntable 1 rotates the screw to the inclined washer track 2, the inclined washer track 2 is used to reduce the distance between the washer and the upper end of the screw rod. , so that when a screw whose rod length is shorter than the radius of the washer rotates with the screw turntable 1, the upper end of the screw rod can be inserted into the round hole in the middle of the washer to achieve combination. The upper end of the screw rod passes through the second screw rod socket 303 and the first screw rod socket 202 and then is inserted into the round hole in the middle of the washer, so that the washer and the upper end of the screw rod are combined in a sleeved manner. The screw turntable 1 continues to drive the screw inserted into the washer to rotate, so that the upper end of the screw rod passes through the third screw rod socket 402. When the screw rotates, the front and rear end surfaces of the upper end of the washer are pressed down through the pressing plate 401, so that the upper end of the washer moves to the lower end of the screw rod under the action of the downward pressure to achieve stable combination.
