The positioning rod 42 and the positioning hole 43 are plug-in structures, and the connecting block 44 and the connecting groove 41 are both T-shaped structures.

[0022] By adopting the above technical solution, the connecting block 44 at the bottom of the upper shell 1 slides into the connecting groove 41 in the lower shell 7. Under the connection limit between the T-shaped connecting block 44 and the connecting groove 41, the connection strength between the upper shell 1 and the lower shell 7 can be made higher. The connection between the positioning rod 42 and the positioning hole 43 can enable the connecting block 44 to be installed and positioned in the connecting groove 41.

[0023] Specifically, a side plate is connected to the side end of the positioning rod 42 , and two springs 45 are connected between the side plate of the positioning rod 42 and the lower shell 7 .

[0024] By adopting the above technical solution, under the pulling action of the spring 45 , the positioning rod 42 and the positioning hole 43 are tightly plugged together, so that the connecting block 44 can be installed and positioned firmly in the connecting groove 41 .

[0025] When this embodiment is used, the two steel structure bodies 5 are connected and placed on the top plate 6 in the lower shell 7, and then the connecting block 44 at the bottom of the upper shell 1 is slid into the connecting groove 41 in the lower shell 7. The connection limit between the T-shaped connecting block 44 and the connecting groove 41 can make the connection strength between the upper shell 1 and the lower shell 7 higher. Under the pulling action of the spring 45, the tight insertion between the positioning rod 42 and the positioning hole 43 can make the connecting block 44 installed and positioned firmly in the connecting groove 41. The pressing and positioning of the steel structure body 5 is completed by adjusting the downward movement of the pressure plate 3 by two threaded rods. Example

[0026] The difference between this embodiment and embodiment 1 is that the regulating component 2 includes a rotating shaft 21, a threaded barrel 22, a screw 23, a support 25, a bevel gear 1 26 and a bevel gear 27.

The downward movement of the pressure plate 3 can complete the pressing and positioning of the steel structure body 5. The adjustment operation is simple and the use effect is better.

[0029] Specifically, the surface of the screw rod 23 inside the upper shell 1 and the surface of the rotating shaft 21 inside the support 25 are both covered with a limiting block 24, and the limiting block 24 is a circular ring structure.

[0030] By adopting the above technical solution, under the action of the limit block 24, the meshing transmission between the bevel gear 1 26 and the bevel gear 2 27 can be made more stable and firm, and the control effect can be better.

[0031] When this embodiment is in use, the rotating shaft 21 is rotated under the action of the limit block 24 to drive the two bevel gears 26 to rotate in a limited position, and the two screws 23 can be driven to rotate synchronously under the meshing transmission between the bevel gear 26 and the bevel gear 2 27. The meshing connection between the screw 23 and the threaded tube 22 can make the two threaded tubes 22 synchronously drive the pressure plate 3 to move downward. The downward movement of the pressure plate 3 can complete the pressing and positioning of the steel structure body 5. The adjustment operation is simple and the use effect is better.

Its working principle is to connect the two steel structure bodies 5 and place them on the top plate 6 in the lower shell 7, and then cover the upper shell 1 and assemble them with the lower shell 7 through fixing bolts, and adjust the pressure plate 3 downward by two threaded rods to complete the pressing and positioning of the steel structure body 5.

[0033] The working principle and use process of the utility model: when the utility model is used, the two steel structure bodies 5 are connected and placed on the top plate 6 in the lower shell 7, and then the connecting block 44 at the bottom of the upper shell 1 is slid into the connecting groove 41 in the lower shell 7. Under the connection limit between the T-shaped connecting block 44 and the connecting groove 41, the connection strength between the upper shell 1 and the lower shell 7 can be made higher.
