[0031] Please refer to Figure 1 , 2The clamping assembly 200 includes a rotating column 210, a first clamping plate 220, a second clamping plate 230, and a third clamping plate 240. The rotating column 210 is rotatably arranged on one side of the claw 120. The first clamping plate 220 is fixedly connected to the rotating column 210. The second clamping plate 230 is fixedly connected to the rotating column 210. The third clamping plate 240 is fixedly connected to the rotating column 210. The positioning clamping rod 150 is clamped to the rotating column 210.
[0032] The elastic member 130 includes a housing 131, a limiting ring 132, and a spring 133. The housing 131 is fixedly connected to the claw 120. The positioning clamping rod 150 is slidably penetrated through the housing 131. The limiting ring 132 is fixedly sleeved on the positioning clamping rod 150. The spring 133 is sleeved on the surface of the positioning clamping rod 150. By arranging the housing 131, the limiting ring 132, and the spring 133, the spring 133 is used to elastically push the limiting ring 132. The limiting ring 132 drives the positioning clamping rod 150 to keep clamping the rotating column 210, so that the adjusted rotating column 210 is positioned.
[0033] In this embodiment, one end of the positioning clamping rod 150 is fixedly connected with a pull ring 151. By arranging the pull ring 151, it is convenient to rotate the pull ring 151 to drive the positioning clamping rod 150 to move.
