A limiting post 203 is fixed inside the mounting bracket 101. The first lead screw 202 is vertically threaded through the connecting block 204, controlling the connecting block 204 to slide along the limiting post 203. An arc-shaped clamping plate 205 is fixed on the side of the connecting block 204 near the rotating mechanism 3. The first lead screw 202 adopts a double-ended screw structure with opposite thread directions on both sides. There are two sets of connecting blocks 204 and clamping plates 205, which are symmetrically connected on both sides of the first lead screw 202.
[0029] like Figure 1-2 As shown, the rotating mechanism 3 is mounted on the upright plate 102. The rotating mechanism 3 includes a rotating frame 302, which is rotatably mounted on the upright plate 102. A moving mechanism 4 is mounted on the rotating frame 302, and a moving frame 5 is slidably mounted on the rotating frame 302, sliding along the rotating frame 302 under the control of the moving mechanism 4. The rotating mechanism 3 also includes a rotating motor 301, a rotating disk 303, and a connecting rod 304. The rotating motor 301 is fixed to the outside of the upright plate 102, and the rotating frame 302 consists of rotating disks 303 on both sides and a middle rotating disk 303. The connecting rod 304 is fixedly connected. One end of the rotating frame 302 passes through the vertical plate 102 and is shaft-connected to the rotating motor 301. The axis of the connecting rod 304 is equidistant from the two side clamps 205. The moving mechanism 4 includes a second motor 401 and a second lead screw 402. The second motor 401 is fixed on the outside of the rotating disk 303. The second lead screw 402 is rotatably located on the inside of the rotating frame 302 and passes through the rotating disk 303 and is shaft-connected to the second motor 401. The second lead screw 402 is vertically threaded through the moving frame 5 to control the movement of the moving frame 5.
[0030] like Figure 1-4 As shown, the movable frame 5 is equipped with an adjustment mechanism 6, which includes an electric telescopic rod 601, a first rotating rod 602, a second rotating rod 603, and a slider 605.
