[0006] Furthermore, the transmission mechanism includes a pin rotatably arranged inside the connecting box, a gear is fixed on the pin, the gear is meshed with a rack, the upper end surface of the pin passes through the upper end surface of the connecting box, the upper end surface of the pin is fixedly connected with a bolt head, and the bolt head facilitates the movement of support plate one and support plate two, thereby driving the clamping plate to clamp the template.

[0007] Furthermore, a top box is connected above the connection box, and the locking mechanism includes a ratchet fixed to the upper end of the pin, the ratchet is arranged inside the top box and above the gear, and a block is engaged and connected to the outer side of the ratchet.

[0008] Furthermore, a sliding rod is fixed on the side of the block away from the ratchet, a slip ring is fixed on the upper end surface of the connecting box, the sliding rod is slidably connected to the inside of the slip ring, a return spring is sleeved on the sliding rod, one end of the return spring abuts against the block, the other end of the return spring abuts against the slip ring, and a limiting block is fixed on the upper end surface of the connecting box on one side of the block.

[0009] Furthermore, one end of the slide bar away from the ratchet wheel passes through the top box and is fixed with a pull ring, so as to facilitate the movement of the slide bar.
