[0024] Specifically, when clamping the steel fireproof door, the opposite sliding of the two groups of clamping plate 5 can realize the clamping and fixing of the fireproof door, in the process, pulley 14 is in advance contacted with the fireproof door, then pulley 14 is forced to slide inward until the fireproof door is contacted with the outer wall of rubber pad 6, and when adjusting the position of the fireproof door, the two groups of slide blocks 4 can be driven to slide relatively, so that pulley 14 is contacted with the fireproof door, and rubber pad 6 is not contacted, at this time, pulley 14 not only keeps the limiting of the fireproof door, but also can horizontally push the fireproof door to slide by means of hydraulic oil cylinder 9, so that the position adjustment is realized while avoiding the position error.

[0025] The reset mechanism includes a limiting block 15 fixedly connected to the end of the connecting rod 13, the radius of the limiting block 15 is larger than that of the connecting rod 13, a spring 16 is sleeved on the outer wall of the connecting rod 13, one end of the spring 16 is fixedly connected to the link plate 12, and the other end of the spring 16 is fixedly connected to the outer wall of the limiting block 15.

[0026] Specifically, the elastic force of the spring 16 realizes the automatic reset of the pulley 14, so that the pulley 14 is always contacted with the fireproof door during the adjustment of the position of the fireproof door, and the error value caused by the position adjustment is reduced.

[0027] A double-headed threaded rod 2 is rotatably connected to the inner wall of the processing frame 1, and the two groups of slide blocks 4 are threadedly connected to the threaded segments of the double-headed threaded rod 2.

[0028] Specifically, the design of the double-headed threaded rod 2 enables the two groups of slide blocks 4 to move synchronously towards or away from each other, realizes the quick opening and closing of the clamping plate 5, improves the clamping efficiency, and ensures the uniform distribution of the clamping force.
