[0032] This section will describe in detail the specific embodiments of the utility model. The preferred embodiments of the utility model are shown in the accompanying drawings. The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the utility model, but it cannot be understood as a limitation on the protection scope of the utility model.

[0033] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown:

[0034] Embodiments of the utility model:

[0035] The upper side wall of the adjusting tube 3 is provided with two screw holes 302, and the side wall of the inner sleeve weldment 4 is provided with two screw holes 401. The inner sleeve weldment 4 is inserted into the adjusting tube 3, and the bolt 7 passes through the screw holes 302 and the screw holes 401 with threaded fitting to fix the inner sleeve weldment 4 and the adjusting tube 3. The two screw holes 302 and the two screw holes 401 can adjust the relative positions of the inner sleeve weldment 4 and the adjusting tube 3.

[0036] The inner sleeve weldment 4 is used for fixing on the ceiling.

[0037] A nut 103 is welded to the through hole formed on the upper portion of the suspension rod 1 .

[0038] A plurality of adjustment holes 301 are formed at the lower portion of the adjustment rod 3 .

[0039] After the adjusting rod 3 is inserted into the suspension rod 1, the rotating plunger 2 is threadedly engaged and passed through the nut 103 and then inserted into the adjusting hole 301, so that the adjusting rod 3 is combined with the suspension rod 1. Several adjusting holes 301 make it possible to adjust the relative position of the adjusting rod 3 and the suspension rod 1, that is, to move the suspension rod 1 up and down and then fix it.

[0040] The safety pull rod 5 is located inside the suspension rod 1 , and the length of the safety pull rod 5 is not less than the length of the suspension rod 1 .

[0041] A bottom through hole three 303 is opened on the adjusting tube bottom plate 31 at the bottom of the adjusting rod 3, the safety pull rod 5 passes through the bottom through hole three 303 and extends into the adjusting rod 3, and the limiting piece 501 at the top of the safety pull rod 5 is located in the adjusting rod 3 and the limiting piece 501 is stuck above the bottom through hole three 303.

[0042] A hanger bottom plate 11 is fixedly disposed at the bottom end of the hanger 1 , and a bottom through hole 101 on the hanger bottom plate 11 is larger than the end of the screw sleeve 6 , so that the screw sleeve 6 can pass through the bottom through hole 101 .

[0043] A bottom baffle plate 12 is fixedly provided inside the hanger 1. The baffle through hole 102 opened in the bottom baffle plate 12 is smaller than the end of the screw sleeve 6. The end of the screw sleeve 6 is stuck under the baffle through hole 102. After the body of the screw sleeve 6 passes through the baffle through hole 102, its internal thread is screwed with the external thread at the bottom end of the safety pull rod 5.
