The technical solution in this embodiment is basically the same as that in Embodiment 1, except that: second clamping devices are respectively arranged at the bottom ends of the suspension beam 1 in this embodiment to increase the connection stability with the hanging tobacco beam in the baking room.

[0042] As Figure 3As shown in the figure, the second clamping device in this embodiment is a U-shaped clamp 5. The top of the U-shaped clamp 5 is attached to the bottom of the suspension beam 1. The U-shaped clamps 5 at both ends of the suspension beam 1 are symmetrically arranged, and the opening directions of the two U-shaped clamps 5 are opposite. A threaded hole is provided at the bottom of the U-shaped clamp 5, and a fastening bolt 502 is installed in the threaded hole. During use, directly clamp the U-shaped clamp 5 on the hanging tobacco beam and tighten the fastening bolt 502 to make the fastening bolt 502 closely fit with the hanging tobacco beam. Threaded holes can also be provided at the bottom of the hanging tobacco beam to connect the fastening bolt 502 with the threaded holes at the bottom of the hanging tobacco beam, further increasing the stability.

[0044] The usage method of the suspension beam 1 provided in this embodiment is as follows: During use, move the push rod 501 so that the push rod 501 moves to the other end of the through slot 102. The push rod 501 drives the U-shaped clamp 5 to move. Then align the U-shaped clamp 5 with the hanging tobacco beam, release the push rod 501, and the push rod 501 drives the U-shaped clamp 5 to move under the elastic force of the spring 104 to make the U-shaped clamp 5 fit with the hanging tobacco beam. Adjust the position of the U-shaped clamp 5 to make the vertical side wall of the U-shaped clamp 5 closely fit with the hanging tobacco beam. Finally, tighten the fastening bolt 502.

[0045] The U-shaped clamp 5 and the fastening bolt 502 provided in this embodiment can increase the connection stability between the suspension beam 1 and the hanging tobacco beam in the baking room; the provided push rod 501 and spring 104 facilitate the connection between the U-shaped clamp 5 and the hanging tobacco beam. When the hanging tobacco beam in the baking room is square, only by making the vertical side wall of the U-shaped clamp 5 closely fit with the hanging tobacco beam can the two ends of the suspension beam 1 be aligned, and there is no need to use a horizontal calibration device, making the installation simpler and more convenient.

At this time, the bottom of the limiting block 606 is closely attached to the top of the lower ear plate 301 located in the second fixing groove 603, so as to limit the lower ear plate 301 and increase the connection stability between the lower ear plate 301 and the hook 6.

[0050] The using method of the hook 6 provided in this embodiment is as follows: When in use, directly hang the lower ear plate 301 at the top of the cigarette clip 3 on the hook 6, so that the lower ear plate 301 is located in the second fixing groove 603, and make the convex block 604 insert into the groove of the lower ear plate 301. Rotate the limiting block 606, and the positioning beads 605 on both sides of the hook 6 are respectively inserted into the corresponding limiting holes 6061 to fix the lower ear plate 301, which is easier to operate compared with connecting by a rope and saves the time for fixing the rope.
