[0006] As a preferred technical solution of the present utility model, the first connecting pipe is fixedly connected to the first end cover, and the second connecting pipe is fixedly connected to the second end cover.

[0007] As a preferred technical solution of the utility model, one side of the first connecting tube and the second connecting tube is provided with a slot, and both ends of the fire-blocking tube can be inserted into the slot.

[0008] As a preferred technical solution of the utility model, a fire-retardant core is arranged in the fire-retardant tube.

[0009] As a preferred technical solution of the utility model, a pair of first fixing plates are fixedly connected to the first end cover, a pair of second fixing plates are fixedly connected to the second end cover, and through holes are provided on both the first fixing plates and the second fixing plates.

[0010] As a preferred technical solution of the utility model, bolts are inserted into the through holes of the first fixing plate and the second fixing plate, and nuts are threadedly connected to the bolts.

[0011] Compared with the prior art, the beneficial effect that the utility model can achieve is: by rotating the lifting ear with force, the first magnet sheet on the lifting ear is separated from the second magnet sheet on the connecting block, and the lifting ear is rotated a certain angle along the cross bar so that the lifting ear is no longer received in the groove of the connecting block, thereby facilitating the lifting tool to connect and fix the lifting holes on the two lifting ears, and the device can be lifted upward by the lifting tool. The device can be used to facilitate lifting operations without the need for separate bundling with a sling, which adds additional operations. BRIEF DESCRIPTION OF THE DRAWINGS
