The connecting block 17 is fixedly connected with a locking pin 18, which passes through the guide hole 6 and is inserted in the limiting hole 7. When the rotating ring block 12 rotates, the arc-shaped sliding groove 14 will squeeze the sliding rod 15, so that the sliding rod 15 moves, but the guide hole 6 plays a limiting role through the connecting block 17 and the locking pin 18, so that the positioning block 16 can only move along the axial direction of the guide hole 6, so that the locking pin 18 is stuck in the guide hole 6, and the connecting rod 3 is fixed and locked. When removing the precast beam template block 1, it is only necessary to rotate the rotating rod 11 in the opposite direction to cancel the fixation between the two precast beam template blocks 1, so that the precast beam template block 1 can be disassembled. The device does not need to be fixed by external parts, and the installation and disassembly operations are simple and quick, which can improve the fixed installation efficiency between the precast beam template blocks 1 and the dismantling efficiency when the precast beam template blocks 1 are removed.

[0027] like Figure 1-6 As shown, the diameter of the guide hole 6 matches the locking pin 18, thereby improving the connection stability after insertion.

[0028] like Figure 1-6 As shown, three groups of arc-shaped slide grooves 14 and slide rods 15 are provided, and are arranged in a uniform circular array around the axis of the plug-in rod 13. The three-point fixation has strong stability and can make the force on the lock pins 18 at various locations uniform and stable.

[0034] Working principle: When connecting two prefabricated beam template blocks 1, align the two prefabricated beam template blocks 1 so that the adjacent connecting rods 3 are inserted into their corresponding guide grooves 20. A positioning block 16 is provided in the guide groove 20, and a guide slide groove 21 is provided on the positioning block 16. A guide slide groove 21 is provided in the connecting rod 3. The guide slide groove 21 cooperates with the guide slide groove 21 to guide the connecting rod 3, so that the connecting rod 3 is aligned with the guide groove 20. Then, the rotating rod 11 drives the worm 8 to rotate through the connecting handle 2. The end of the rotating rod 11 is fixedly connected with a ball handle 10. Its spherical protrusion can be surrounded by fingers or palms, which can provide better grip and control, and is convenient for rotating or twisting the connecting handle 2. When rotating, the worm 8 cooperates with the worm wheel block 9 to drive the rotating ring block 12 to rotate, and the cooperation between the worm 8 and the worm wheel block 9 is self-locking. 8 has a higher torque transmission capacity, can withstand a larger load, and provides additional safety and stability. When the rotating ring block 12 rotates, the arc-shaped slot 14 will squeeze the slide rod 15, so that the slide rod 15 moves, but the guide hole 6 plays a limiting role through the connecting block 17 and the locking pin 18, so that the positioning block 16 can only move along the axial direction of the guide hole 6, so that the locking pin 18 is stuck in the guide hole 6, and the connecting rod 3 is fixed and locked, and the fixation between the two prefabricated beam template blocks 1 can be completed. When the prefabricated beam template blocks 1 are removed, it is only necessary to rotate the rotating rod 11 in the opposite direction to cancel the fixation between the two prefabricated beam template blocks 1, and the prefabricated beam template blocks 1 can be removed. The device does not need to be fixed by external parts, and the installation and disassembly operations are simple and quick, which can improve the fixing and installation efficiency between the prefabricated beam template blocks 1 and the removal efficiency when removing the prefabricated beam template blocks 1.
