The bottom end of the screw rod 27 penetrates and is rotationally connected with the connecting block 29, the bottom surface of the connecting block 29 is fixedly connected with the supporting plate 210. The top surface of the connecting block 29 is fixedly connected with the abutting block 211, the screw rod 27 penetrates the abutting block 211, the inclined surface of the abutting block 211 forces the supporting rod 212 to rotate, so that the supporting rod 212 gradually pushes the supporting plate 213 to slide along the positioning rod 31, so that the supporting plate 213 gradually pushes the inner side of the first mounting plate 1 and the second mounting plate 4, so that the first mounting plate 1 and the second mounting plate 4 are expanded to adjust the gap of the expansion joint, avoiding the inclination of the gap between the first mounting plate 1 and the second mounting plate 4 causing hidden troubles during expansion. The bottom surface of the linkage block 26 penetrates and is hingedly connected with the supporting rod 212, the end away from the linkage block 26 of the supporting rod 212 penetrates and is hingedly connected with the supporting plate 213, after the linkage block 26 moves downward, the supporting rod 212 moves downward together, when the supporting rod 212 moves above the abutting block 211, the inclined surface of the abutting block 211 forces the supporting rod 212 to rotate, so that the supporting rod 212 gradually pushes the supporting plate 213 to slide along the positioning rod 31, the surface of the supporting plate 213 is provided with the guide hole 215, and the outer surface of the supporting plate 213 is provided with the groove 216.A spring 214 is fixedly connected to the bottom surface of the T-shaped slider 25. Pressing down on the pressure plate 21 and then rotating the handle 28 causes the screw 27 to rotate. Since the T-shaped sliders 25 are fixedly connected to both sides of the linkage block 26, and the T-shaped sliders 25 are inserted into the T-shaped grooves 24 opened on the inner side of the pressure plate 21, when the screw 27 rotates, it will drive the threaded linkage block 26 to slide downward on the inner side of the symmetrical pressure plate 21.

An extension rod 33 is fixedly connected to the surface of the hinge block 32. When the extension rod 33 abuts against the inner side of the first mounting plate 1 and the second mounting plate 4, it will rotate through the hinge block 32. The hinge block 32 will compress the torsion spring 34 and move the extension rod 33 into the groove 216. When the adjusting part 2 is pulled out, the torsion spring 34 will pop out the extension rod 33. The torsion spring 34 is fixedly connected between the extension rod 33 and the inner side of the positioning rod 31.

[0031] In this embodiment, pulling up the clamping plate 21 will cause the entire control part 2 and the positioning part 3 to rise together from between the expansion joints. When the extension rod 33 touches the inner side of the first mounting plate 1 and the second mounting plate 4, it will rotate through the hinge block 32. The hinge block 32 will compress the torsion spring 34 and move the extension rod 33 into the groove 216. After the control part 2 is pulled out, the torsion spring 34 will pop out the extension rod 33. When the first mounting plate 1 and the second mounting plate 4 are installed, the clamping plate 21 can be inserted between the expansion joints to resist the extension rod 33 and retract upwards. However, after the clamping plate 21 is inserted, the torsion spring 34 will still pop out the extension rod 33 to ensure that the support plate 213 can be stably guided when it is pushed.
