A slide rail 27 is provided at the other end of the mounting sleeve rod 21. The two slide rails 27 are both slidably connected to the limit assembly 4. Two guide grooves 271 are provided in the two slide rails 27. Two limit platforms 28 are provided inside the end of the mounting sleeve rod 21 away from the limit plate 23. The two limit platforms 28 are provided with limit grooves 29.

[0027] An adjusting rod 31 is provided on the adjusting assembly 3, a connecting pin 32 is rotatably connected inside the adjusting rod 31, a limiting block 34 is provided on the connecting pin 32, an adjusting handle 33 is provided at one end of the connecting pin 32, the other end of the connecting pin 32 is fixedly connected to a limiting rod 35, one end of the limiting rod 35 is provided with a connecting spring 36, and the end of the adjusting rod 31 away from the adjusting handle 33 is fixedly connected to a transmission platform 37.

[0028] A connecting rope 24 is provided on the limit plate 23, and the other end of the connecting rope 24 is fixedly connected to a threaded sleeve 25, which is adapted to the threaded ring 22. The threaded sleeve 25 is provided so that the adjusting component 3 can be protected after installation, thereby preventing the staff from accidentally touching it. Specifically, the staff can cover the adjusting component 3 with the threaded sleeve 25, and then thread the threaded sleeve 25 with the threaded ring 22, thereby achieving the protection effect on the adjusting component 3.

[0029] One end of the mounting sleeve rod 21 away from the limiting plate 23 is fixedly connected with a connector 26, and the transmission platform 37 is fixedly connected to the connector 26. This connection method effectively ensures that the adjustment assembly 3 can be reset during use.

[0030] As a preferred technical solution in this embodiment, in actual use, the staff can first insert the installation sleeve rod 21 into the installation holes provided on the installation seat 11 and the prefabricated beam 12 until the limit plate 23 is kept in contact with the installation seat 11. At this time, the other end of the installation sleeve rod 21 is located on the other side of the installation seat 11. Then the staff can control the adjustment handle 33 to drive the adjustment rod 31 to slide in the installation sleeve rod 21. During the sliding process of the adjustment rod 31, the transmission platform 37 can be driven to move. During the displacement of the transmission platform 37, the limit assembly 4 can be driven to slide in the slide rail 27, so that the limit assembly 4 can realize the installation sleeve rod 21. The limiting rod 35 will be displaced downward under the action of the elastic force of the connecting spring 36 and thus be clamped in the limiting groove 29. The limiting groove 29 realizes the limiting effect on the limiting rod 35, and the limiting assembly 4 realizes the installation effect on the mounting sleeve rod 21.

[0031] Embodiment 2:

[0032] See also Figure 5In order to achieve the effect of quick disassembly, the two limit assemblies 4 in this embodiment are provided with slides 41, both slides 41 are slidably connected to the slide rail 27, and the opposite sides of the two slides 41 are provided with stop plates 42. The slide 41 is provided with two sliders 43, both sliders 43 are slidably connected to the guide groove 271, and the slider 43 is provided with a return spring 44, and the other end of the return spring 44 is fixedly connected to the guide groove 271.

[0033] As a preferred technical solution in this embodiment, during actual use, when the staff needs to disassemble the installation sleeve rod 21 to cancel the limiting effect on the precast beam 12, the staff can press the adjustment handle 33 to make the limiting rod 35 disengage from the limiting groove 29, and then the staff can rotate the limiting rod 35 to be located in the gap between the two limiting platforms 28. Finally, the staff can pull the adjustment handle 33 to drive the limiting rod 35 and the transmission platform 37 to produce a displacement effect. When the transmission platform 37 is displaced to be separated from the two slides 41, the slide 41 will retreat under the action of the reset spring 44, thereby canceling the limiting effect on the installation sleeve rod 21. Subsequently, the staff can achieve the effect of quick disassembly by pulling out the installation sleeve rod 21 from the mounting seat 11.

[0034] The working principle of the above embodiment is:

[0035] 1. The staff can first insert the installation sleeve rod 21 into the installation holes provided on the installation seat 11 and the prefabricated beam 12 until the limit plate 23 is kept in contact with the installation seat 11. At this time, the other end of the installation sleeve rod 21 is located on the other side of the installation seat 11. Then the staff can control the adjustment handle 33 to drive the adjustment rod 31 to slide in the installation sleeve rod 21. During the sliding process of the adjustment rod 31, the transmission platform 37 can be driven to move. During the displacement process of the transmission platform 37, the limit assembly 4 can be driven to slide in the slide rail 27, so that the limit assembly 4 can achieve the effect of limiting the installation sleeve rod 21. When the limit assembly After the installation sleeve rod 21 is limited, the connection spring 36 is located above the limit platform 28 and the connection spring 36 is compressed. Then the staff can control the adjustment rod 31 to rotate, and the connection pin 32 rotates. During the rotation of the connection pin 32, the limit rod 35 can be driven to rotate until the limit rod 35 rotates to the top of the limit groove 29. At this time, the staff can loosen the adjustment handle 33 to remove the force. The limit rod 35 will move downward under the action of the elastic force of the connection spring 36 and be clamped in the limit groove 29. The limit groove 29 realizes the limiting effect of the limit rod 35, and the limit assembly 4 realizes the installation effect of the installation sleeve rod 21.

[0036] 2. In actual use, when the staff needs to disassemble the installation sleeve rod 21 to cancel the limiting effect on the precast beam 12, the staff can press the adjustment handle 33 to make the limiting rod 35 disengage from the limiting groove 29, and then the staff can rotate so that the limiting rod 35 is located in the gap between the two limiting platforms 28. Finally, the staff can pull the adjustment handle 33 to drive the limiting rod 35 and the transmission platform 37 to produce a displacement effect. When the transmission platform 37 is displaced to be separated from the two slides 41, the slide 41 will retreat under the action of the reset spring 44, thereby canceling the limiting effect on the installation sleeve rod 21. Subsequently, the staff can achieve the effect of quick disassembly by pulling out the installation sleeve rod 21 from the mounting seat 11.
