A first wire guiding wheel 105 is fixedly connected to the upper surface of the lifting plate 104, a lifting rope 106 is wound around the first wire guiding wheel 105, and in order to ensure that the lifting rope 106 has sufficient tensile strength and high temperature resistance, a steel wire rope is generally selected, and one end of the lifting rope 106 is connected to the top wall of the rectangular groove 101. A guide rope cavity 1011 is formed at the upper end of the oven box 100, a second guide wire wheel 107 is arranged in the guide rope cavity 1011, and a third guide wire wheel 108 is arranged at the upper end of the inner wall of the rectangular groove 101, so that the other end of the lifting rope 106 sequentially bypasses the third guide wire wheel 108 and the second guide wire wheel 107 and extends into the heating cavity of the oven box 100.

Referring to fig. 2 and 3, the end of the lifting rope 106 extending into the oven box 100 is connected with an anti-falling lifting hanger 200, and two side walls of the inner cavity of the oven box 100 are fixedly connected with anti-falling clamping racks 300 matched with the anti-falling lifting hanger 200.

Referring to fig. 4 and 5, the anti-falling lifting and hanging frame 200 comprises a U-shaped frame 201 and a lifting and hanging rod 202, wherein a bolt rod 203 connected with the upper end of a lifting frame (not shown in the figure) is inserted at the two lower ends of the U-shaped frame 201, and the lifting frame and the anti-falling lifting and hanging frame 200 can be quickly assembled and connected through the action of the bolt rod 203. Two L-shaped rods 204 which are symmetrically arranged are arranged in the U-shaped frame 201, and the right angles of the two L-shaped rods 204 are rotatably connected with a connecting piece 205 on the U-shaped frame 201. The upper end of the lifting rod 202 is connected with the end of the lifting rope 106, and the lower end of the lifting rod is arranged through the middle section of the U-shaped frame 201. The lower end of the lifting rod 202 is connected with a rotating part 206, a compression spring 207 is sleeved on the lifting rod 202 between the U-shaped frame 201 and the rotating part 206, and then the end parts of the two L-shaped rods 204 close to each other are rotatably connected with the rotating part 206.
