[0017] See also Figure 1-3The utility model provides a technical solution: a formwork support connector, including an upper fastener 1 and a lower fastener 2, the upper fastener 1 and the lower fastener 2 are both arc-shaped structures and the opening directions are corresponding, studs 3 are inserted on both sides of the upper fastener 1 and the lower fastener 2, nuts 4 are connected to the upper and lower ends of the studs 3 and the connection between the upper and lower fasteners 1 and the lower fasteners 2, and the outer ends of the upper and lower fasteners 1 and the lower fasteners 2 are welded and fixed with reinforcement blocks 5, and the reinforcement blocks 5 are embedded and installed with reinforcement shafts 6 in the same group, and the upper and lower ends of the reinforcement shafts 6 are sleeved with movable sleeves 7, and the inner sides of the movable sleeves 7 are fixedly connected with reinforcement sleeves 8 through connecting blocks, and the reinforcement sleeves 8 are sleeved on the outside of the studs 3 and pressed against the outside of the nuts 4. The upper fastener 1 and the lower fastener 2 of this structure are closed to the steel tubular support. When connecting, the stud 3 can be inserted into both sides of the upper fastener 1 and the lower fastener 2 and locked with the nut 4, and the reinforcement shaft 6 can also be embedded in the corresponding group of reinforcement blocks 5, and then the movable sleeve 7 can drive the reinforcement sleeve 8 to be sleeved on the outside of the stud 3 and pressed against the outside of the nut 4 by sliding on the outside of the reinforcement shaft 6. The nut 4 is more firmly connected to the outside of the stud 3 under the restriction of the reinforcement sleeve 8, so that the upper fastener 1 and the lower fastener 2 can be more firmly connected and fixed to the support, and the connection of the support can be played as an auxiliary fixation to form a stable fastening effect, avoiding the problem that the upper fastener 1 and the lower fastener 2 are limited in the connection area of ​​the support, which easily leads to the problem of one side being tilted, thereby ensuring the effect of the support on the building formwork, and reinforcing the shaft 6. A fixing ring 9 is also provided at both upper and lower ends, and a tension spring 10 sleeved on the outside of the reinforcement shaft 6 is provided between the fixing ring 9 and the movable sleeve 7. When the movable sleeve 7 of this structure is pulled on the outside of the reinforcement shaft 6, it can drive the tension spring 10 to stretch under the cooperation of the fixing ring 9, so that the movable sleeve 7 can smoothly drive the reinforcement sleeve 8 to be sleeved on the outside of the stud 3, and the reinforcement sleeve 8 can press the nut 4 more firmly under the action of the tension spring 10. The outer side of the fixing ring 9 is provided with a fitting mouth 11 that matches the structure of the reinforcement shaft 6, and the inner wall of the fitting mouth 11 is an arc-shaped structure. Metal baffles 12 are symmetrically welded and fixed at the opening of the fitting mouth 11. The metal baffles 12 have a certain elastic force, and a rubber pad is bonded and fixed to the inner wall of the fitting mouth 11. The reinforcing shaft 6 of this structure can be embedded in the fitting opening 11 by squeezing the metal baffle 12, so as to be quickly installed in the corresponding group of reinforcing blocks 5. The installation operation process is more convenient and quick, and the metal baffle 12 can limit the reinforcing shaft 6 to ensure the stability of the reinforcing shaft 6 when it is installed on the same group of reinforcing blocks 5. The inner side of the fixing ring 9 is attached to the corresponding side of the reinforcing block 5, and the fixing ring 9 is fixedly sleeved on the outside of the reinforcing shaft 6. The fixing ring 9 of this structure can be attached to the corresponding side of the reinforcing block 5 to further improve the stability of the reinforcing shaft 6 when it is installed on the same group of reinforcing blocks 5. Both sides of the upper fastener 1 and the lower fastener 2 are provided with horizontal sections, and the horizontal sections on both sides of the upper fastener 1 and the lower fastener 2 are provided with through holes that match the structure of the stud 3.In this structure, the horizontal sections at both ends of the upper fastener 1 and the lower fastener 2 can be inserted through the holes with the studs 3 to achieve the function of quickly connecting and fixing the connecting parts.

[0018] Working principle: When using the template support connector, first close the upper fastener 1 and the lower fastener 2 to connect the steel tubular support, then the horizontal sections at both ends of the upper fastener 1 and the lower fastener 2 can be inserted through the holes and the studs 3 can be locked with nuts 4. After the two sets of studs 3 and nuts 4 are installed, the reinforcement shaft 6 is embedded in the corresponding set of reinforcement blocks 5. The metal baffle 12 will be squeezed when the reinforcement shaft 6 is embedded. Until the reinforcement shaft 6 is completely embedded in the embedding opening 11, the metal baffle 12 can limit the reinforcement shaft 6, and the fixing ring 9 will also fit on the reinforcement block 5. On the corresponding side, the stability of the reinforcement shaft 6 when it is installed on the same group of reinforcement blocks 5 is ensured. At the same time, the movable sleeve 7 is slid on the outside of the reinforcement shaft 6. When the movable sleeve 7 is pulled on the outside of the reinforcement shaft 6, it will drive the tension spring 10 to stretch with the cooperation of the fixing ring 9 until the reinforcement sleeve 8 corresponds to the position of the stud 3. Then, the reinforcement sleeve 8 is released. The reinforcement sleeve 8 will be firmly pressed against the outside of the nut 4 under the action of the tension spring 10. At this time, the upper fastener 1 and the lower fastener 2 will have a better effect on fastening the support connection under the stability of the reinforcement shaft 6 and the reinforcement sleeve 8, thereby completing a series of tasks.
