[0022] Embodiment 2:

[0023] Figure 1 , Figure 2 , Figure 3 In the embodiment shown, the hand-cranked tilting and lifting structure includes a threaded vertical rod 20, a threaded rod base 21 and a top hand-cranked handle, the threaded vertical rod 20 is fixedly connected to the threaded rod base 21, and the top of the threaded vertical rod is connected with a top hand-cranked handle (different from the hand-cranked handle 23 in the first embodiment, the top hand-cranked handle can be directly inserted into the top of the threaded vertical rod 20 and can also be a directly fixed connection handle connection structure); the permanent magnet fixing seat is provided with a tilting and lifting connection seat 12, and the tilting and lifting connection seat 12 is threaded and movably connected with the threaded vertical rod 20. The rest is the same as the first embodiment.

[0024] During use, when an anchoring and traction connection is required, the hand crank handle 23 and the threaded connection base 231 are movably connected and arranged at a position above the other end of the top rocker arm 22. The top rocker arm 22 can be easily rotated and shaken from the hand crank handle 23 above the other end of the top rocker arm 22, so that the bottom end surface of the threaded rod base 21 is higher than the area above the bottom end surface of the fixed seat body 10, thereby ensuring that the magnetic contact surface between the fixed seat body 10 and the permanent magnet 40 and the anchoring carrier is not affected by the bottom end surface of the threaded rod base 21, so as to achieve stable and strong magnetic attraction between the magnetic contact surface between the fixed seat body 10 and the permanent magnet 40 and the anchoring carrier, and then realize the anchoring and traction operation through the traction connection between the anchoring traction ring 30 and the traction rope.
