The surface of the cam 97 pushes the block 99, and drives the first positioning block 92 to move through the push block 99. The first positioning block 92 drives the adjusting block 910 to move. The adjusting block 910 pulls the limiting rod 142 to move through the limiting piece 143. The limiting rod 142 stretches the tension spring 141.
