[0010] Beneficial effects:

[0011] 1. In the present invention, by setting the T-shaped slot, strip hole, T-shaped slider, pull rod, spring and U-shaped clamping ring, the inner and outer templates can be easily and quickly disassembled and assembled, and the position of the pull rod can be freely adjusted. On the one hand, the pull rod is ensured to pass through the existing hole or non-load-bearing area as much as possible to ensure the strength of the wall structure. On the other hand, sufficient space can be provided to facilitate the disassembly and assembly of the inner and outer templates. Specifically, when the inner and outer templates need to be connected and fixed, it is only necessary to pull the pull rod hard to make the U-shaped clamping ring correspond to the slot position. At this time, the spring is stretched, and then the U is slid The U-shaped clamping ring is used to cooperate with the slot, and the pulling force is finally withdrawn. The elastic force of the spring can be used to clamp and fix the inner and outer templates. In the above process, the pull rod can be adjusted by sliding the pull rod to pass through the wall. When disassembling, pull the pull rod hard to ensure that the pulling force offsets the elastic force of the spring, and then slide the U-shaped clamping ring to separate it from the slot. Compared with the existing bolt connection method, it can greatly reduce the disassembly and assembly time. At the same time, it has smaller requirements on the operating space size and can adapt to the installation in narrow spaces. In addition, it can avoid the problem of thread jamming caused by rust or slipping, which makes it impossible to disassemble.

[0012] 2. In the utility model, by setting up multiple groups of card slots, it can be suitable for use on walls of different thicknesses. At the same time, the spring elastic force can be adjusted according to the cooperation with different card slots, thereby adjusting the clamping force of the inner template and the outer template; by setting up the telescopic rod, on the one hand, it can ensure the linear movement of the spring and improve the service life of the spring, and on the other hand, it can facilitate the movement of the pull rod along the groove direction of the T-shaped slide groove; by setting up the protective cover, the spring can be protected and the service life of the spring can be further improved.

[0013] 3. In the utility model, the setting of the pull ring can facilitate the movement of the pull rod, thereby facilitating the matching or separation of the U-shaped clamping ring and the clamping groove. Specifically, at the construction site, the pull ring can be inserted through the steel bar or steel pipe to exert force, thereby achieving the effect of saving time and effort.

[0014] 4. In the utility model, by setting the first connecting plate, the second connecting plate, the third connecting plate and the fourth connecting plate, they can be freely combined according to the height of the wall, and have a wide range of adaptability. Combined with the setting of only the first connecting plate with a T-shaped slide groove, the number of pull rods can be reduced and the installation efficiency can be improved on the basis of ensuring the connection strength; by setting the boss and the groove, the connection between the first connecting plate and the second connecting plate or the third connecting plate and the fourth connecting plate can be easily realized, and the connection strength can be ensured.
