Beneficial effects

[0012] 1. The utility model clamps two circular edge fixtures on the shoulders of the two shafts to be separated, and then rotates the screw at the upper part. The screw is threadedly connected to the H-shaped platform block, and the screw is rotatably connected to the middle circular fixture, so that the H-shaped platform block moves up and down. Through the linkage of the linkage, the upper and lower screws rotate synchronously, and the two H-shaped platform blocks move in opposite directions synchronously. The reverse movement of the two circular edge fixtures is driven by the connecting rod to achieve the effect of separating the two shafts.

[0013] 2. The utility model has a simple structure. The linkage device can realize the synchronous movement of the two screws and the synchronous reverse movement of the two H-shaped platform blocks, thereby ensuring the horizontal reverse movement of the two edge circular clamps and preventing the edge circular clamps from being skewed due to the asynchronous movement of the two H-shaped platforms.

A nut is welded to the end of the screw at the upper part, which is used to rotate the screw during operation. Each of the screws is threadedly connected to an H-shaped platform block 3, and the H-shaped platform block is hinged to the side circular clamp through a connecting rod 2;
