Two limit holes 12 are provided on the surface of the output shaft of the driving motor 3. A penetrating hole 13 is provided on the surface of the loading and unloading column 11. A limit bolt 14 is slidably inserted into the limit hole 12. The bottom end of the limit bolt 14 passes through the limit hole 12 and the penetrating hole 13 and is threadedly connected with a nut 15.

[0024] In use, when the threads on the threaded post 4 are deformed or damaged, the staff will first unscrew the nut 15 from the limit bolt 14, and then the staff will pull out the limit bolt 14 from the limit hole 12. Then, the staff can apply a lateral force to the threaded post 4, and then the loading and unloading post 11 can be pulled out from the inside of the sleeve groove 10, thus completing the disassembly of the damaged threaded post 4, which increases the convenience of the staff when loading and unloading the threaded post 4.

[0025] As Figures 3 - 4 shown, a number of fixing openings 16 are formed in the inner bottom surface of the connection grid 2. A fixing bolt 17 is rotatably inserted into the fixing opening 16.
