The clamping jaw assembly 40 is disposed at the lower end of the connecting plate 31. When the cam 23 rotates until its short-diameter surface 231 abuts against the driven wheel 32, the clamping jaw assembly 40 is located at a low position. When the cam 23 rotates until its long-diameter surface 232 abuts against the driven wheel 32, the clamping jaw assembly 40 is located at a high position. Please refer to Figure 4 As shown, the connecting plate 31 is slidably disposed on the bracket 10 via a vertical guide rail (not shown), and a vertically disposed spring 332 is also provided between the connecting plate 31 and the bracket 10.
