[0062] Furthermore, when the small blade 4 or the middle blade 5 needs to be opened, the pull ring 84 at the end of the traction rope 81 is sleeved on the tension screw 89 of the high-position limiting screw 87 and locked by the limiting nut to prevent the pull ring 84 from slipping.

[0063] When the small blade 4 or the middle blade 5 needs to be closed, the pull ring 84 at the end of the traction rope 81 is sleeved on the tension screw 89 of the low-position limiting screw 88 and locked by a limiting nut to prevent the pull ring 84 from slipping off.
