[0026] The second driving member 23 is provided on the first moving part 22. The second driving member 23 is preferably a pneumatic cylinder, which is provided inside the middle part of the connecting arm 222 and between the two mounting arms 221. The output end of the second driving member 23 is power connected with the second moving part 24 to drive the second moving part 24 in the forward and backward direction. The second moving part 24 comprises two mounting arms 241 and a connecting arm 242 connecting the two mounting arms 241. The end of the mounting arm 241 is provided with an upper clamping jaw 243 cooperating with the lower clamping jaw 223.
