[0038] According to the attached Figure 2 -4 shown, it includes:

[0039] The main body circular tube 1, the hoisting plate member 2, the damping steel plate 3 and the fixing component 4. The main body circular tube 1 is used to dock with the circular tube at the end of the cement block. A docking hole corresponding to the hoisting plate member 2 is opened at the end of the main body circular tube 1. An ear part 21 is provided at the top of the hoisting plate member 2, and the ear part 21 is used to limit the insertion depth of the main body circular tube 1. A wiring hole 22 for connecting a steel wire rope is opened on the ear part 21. When the main body circular tube 1 is inserted into the circular tube of the cement block until the ear part 21 on the hoisting plate member 2 fits against the cement pipe, and since the ear part 21 has a certain protruding length, the steel wire rope connected to the ear part 21 does not contact the cement block, thus avoiding the mutual friction between the cement block and the steel wire rope when the cement block is hoisted. A dragging long hole 23 is opened on one side of the hoisting plate member 2. An alignment part 24 flush with the top of the main body circular tube 1 is provided at the top of the hoisting plate member 2. The damping steel plate 3 is fixedly connected to the bottom of the main body circular tube 1. When the main body circular tube 1 is inserted into the circular tube of the cement block and the cement block is hoisted, the bottom of the damping steel plate 3 is pressed against and fits with the inner wall of the circular tube on the cement block, thereby improving the connection stability between the main body circular tube 1 and the circular tube on the cement block. A protruding part 25 not lower than the damping steel plate 3 is provided at the bottom of the hoisting plate member 2. The fixing component 4 is arranged at the end of the main body circular tube 1, and the hoisting plate member 2 is fixedly installed with the main body circular tube 1 through the fixing component 4.

[0040] Further, the fixing component 4 includes a second sealing plate 42 and a locking component 43. The second sealing plate 42 is arranged at the end of the main body circular tube 1. The second sealing plate 42 can seal the end of the main body circular tube 1 to prevent dust and stones from entering when the main body circular tube 1 is inserted into the circular tube of the cement block. The locking component 43 is arranged inside the main body circular tube 1. The second sealing plate 42, the main body circular tube 1 and the hoisting plate member 2 are mutually clamped through the locking component 43. First guiding plates 44 are symmetrically and fixedly connected to the inner wall of the main body circular tube 1. Second guiding plates 45 are symmetrically arranged outside the first guiding plates 44. One side of the second guiding plates 45 is fixedly connected to the hoisting plate member 2. The first guiding plates 44 and the two second guiding plates 45 can improve the stability of the hoisting plate member 2 inserted into the main body circular tube 1.

[0041] In particular, the locking component 43 includes a first arc plate 431, a second arc plate 432, a positioning plate 433 and a positioning block 434. The first arc plate 431 and the second arc plate 432 are symmetrically and slidably sleeved inside the main body circular tube 1. One side of the first arc plate 431 and the second arc plate 432 is fixedly connected to the hoisting plate member 2. The positioning plate 433 is fixedly connected to one side of the second sealing plate 42. The positioning block 434 is fixedly connected to the top of the positioning plate 433. A positioning hole matching the positioning block 434 is opened at the bottom of the first arc plate 431. The positioning block 434 is clamped with the positioning hole on the first arc plate 431, which can not only limit the second sealing plate 42, but also the second sealing plate 42 can clamp and limit the hoisting plate member 2 through the positioning plate 433, the positioning block 434 and the first arc plate 431.

[0042] Further, guide rods 436 are symmetrically and slidably inserted and sleeved at the bottom of the positioning plate 433. A limiting spring 435 is slidably sleeved on the outer wall of the guide rod 436. The limiting spring 435 is located on the side of the positioning plate 433 away from the positioning block 434. The limiting spring 435 can give a elastic force to the positioning plate 433, so that the positioning plate 433 drives the positioning block 434 to maintain a stable clamping state with the first arc plate 431. Arc grooves 439 are symmetrically formed on the opposite sides of the first arc plate 431 and the second arc plate 432. The end of the outer wall of the guide rod 436 is slidably clamped with the arc groove 439. Grooves 4310 matching the guide rods 436 are formed on the opposite sides of the first arc plate 431 and the second arc plate 432. The inner cavity of the groove 4310 is communicated with the inner cavity of the arc groove 439. And the second sealing plate 42 is vertically slid, so that the second sealing plate 42 drives the positioning block 434 to separate from the first arc plate 431 through the positioning plate 433, and the second sealing plate 42 is rotated, so that the second sealing plate 42 drives the guide rod 436 to slide from the arc groove 439 to the groove 4310 through the positioning plate 433, and then the second sealing plate 42 can be slid away from the main body circular tube 1, so that the guide rod 436 slides and separates from the first arc plate 431 and the second arc plate 432, and the second sealing plate 42 and the lifting plate member 2 on the main body circular tube 1 can be disassembled and maintained, so as to facilitate the separate disassembly and maintenance of the main body circular tube 1 and the lifting plate member 2. A first fixing collar 437 is fixedly sleeved at the top of the outer wall of the guide rod 436. Grooves matching the first fixing collar 437 are symmetrically formed at the top of the positioning plate 433. A second fixing collar 438 is fixedly sleeved at the bottom of the outer wall of the guide rod 436. The bottom of the second fixing collar 438 is attached to the second arc plate 432. The first fixing collar 437 and the second fixing collar 438 are used to limit the guide rod 436 and the limiting spring 435 connected to the positioning plate 433, to prevent the guide rod 436 and the limiting spring 435 from directly separating from the second sealing plate 42 when the second sealing plate 42 is disassembled, and the first fixing collar 437 and the second fixing collar 438 do not affect the elastic limiting function of the limiting spring 435 on the positioning plate 433.
