After the adjustment is completed, the two finger cylinders 443 pull the wrench 651, so that the wrench 651 drives the limit member 652 to abut against the installation frame 61, and then enters the next process.

[0040] like Figure 7 As shown, the frame structure 5 includes a second mounting seat 51, a third motor 52, a fifth sprocket 53, a sixth sprocket 54, two seventh sprockets 55, two eighth sprockets 56, a second transmission shaft 57, a third chain, and two fourth chains 58.
