[0032] In other embodiments, the top of the pull rod 18 is provided with a spherical design, and the outer wall of the pull rod 18 is plastered;

[0033] This design increases the contact area between the top end of the pull rod 18 and the user's hand, making it easier to effectively hold the top end of the pull rod 18.

[0034] In other embodiments, the outer wall of the movable block 15 is fully fitted with the inner wall of the sleeve 14, and the movable block 15 and the sleeve 14 are slidably connected;
