[0029] A lower pressing plate 214 is slidably installed inside the lower pressing tube sleeve 211, a compression spring 215 is connected between the lower pressing plate 214 and the lower pressing tube sleeve 211, a sliding frame 216 is fixed to the bottom end of the lower pressing plate 214, an anti-skid plate 217 is rotatably installed at the lower end of the sliding frame 216, the bottom end of the anti-skid plate 217 is tilted close to one end of the clamping seat 204, and a torsion spring 218 is connected between the rotating end of the anti-skid plate 217 and the clamping seat 204.
