In the embodiment of the present disclosure, the sleeve 102 is hinged to the stress application rod 101, and the sleeve 102 is rotatable relative to the stress application rod 101, so as to adjust the position of the sleeve 102, and enable the sleeve 102 to be sleeved on the polish rod. Meanwhile, the sleeve 102 naturally sags by gravity in a natural state, so that the extending direction of the sleeve opening 1021 is consistent with that of the polish rod, and the polish rod can conveniently pass through the sleeve opening 1021.

In the embodiment of the present disclosure, the inner diameter of the sleeve 102 is larger than the diameter of the polish rod, so that the sleeve 102 can move up and down after the sleeve 102 is sleeved on the polish rod. The outer diameter of the sleeve 102 is smaller than the inner diameter of the packing box 3, so that the sleeve 102 can move up and down in the packing box 3.
