In order to achieve the purpose of efficient fixing, when the pressure sensor 14 contacts the door leaf structure, the external controller corresponding to the pressure sensor 14 cuts off the power supply of the cylinder 7, stops the further extension of the cylinder 7, and maintains the clamping effect. The parts not involved in this device are the same as the prior art or can be implemented by the prior art. The structure of the guide block 15 and the guide groove 11 is the same as the structure of the guide strip 10 and the guide opening 16 described below, and plays a guiding role;
[0025] In one embodiment, the cross section of the clamping seat 9 is L-shaped, and the inner height of the clamping seat 9 matches the height of the support frame 5, that is, the door leaf structure placed between the clamping seat 9 and the support frame 5 can maintain a horizontal placement state.

Since the cross-section of the clamping seat 9 is an L-shaped structure, and the height of the inner side of the clamping seat 9 is adapted to the height of the support frame 5, the door leaf structure is suspended above the cutting table 1 under the action of the clamping seat 9 and the support frame 5, and the two clamping seats 9 and the door leaf structure are kept in a clamping state. When the pressure sensor 14 contacts the door leaf structure, the controller set corresponding to the pressure sensor 14 cuts off the power supply of the cylinder 7, stops the further extension of the cylinder 7, maintains the clamping effect, and then starts the cutting on the gantry 2. The cutting machine 3 is adjusted to the door leaf welding position (the driving method between the gantry 2 and the cutting machine 3 is a well-known prior art, and there are mature products, so its principle is not further explained), and then the cutting machine 3 is started to cut the door leaf structure. Before this, since the fixing seat 8 on the outer wall of the cylinder 7 is threadedly connected with the threaded rod 12 by the threaded sleeve 13, by rotating the threaded rod 12, the threaded sleeve 13 is driven to move along the surface of the threaded rod 12 to drive the fixing seat 8 to move horizontally, and the guide block 15 and the guide groove 11 in the placement port 6 are slid to maintain the stability of the movement of the fixing seat 8, so that the cylinder 7 can drive the clamping seat 9 to approach the door leaf structure to be fixed, so as to fix door leaf structures of different sizes.
