[0014] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0015] The utility model provides an oblique-mouth protective coil as shown in the figure, comprising an upper fixed tube body 1, the bottom of the upper fixed tube body 1 is movably connected to a lower fixed tube body 2 through a sealed bearing, an end of the lower fixed tube body 2 away from the upper fixed tube body 1 is provided with an inclined surface and an inclined plate 3 is fixedly connected to the inclined surface, an outer side of the upper fixed tube body 1 is processed with an external thread 6, and a nut assembly 5 is provided on the outer thread of the external thread 6.

[0016] Specifically, a matching ring 4 is fixedly provided at the bottom of the external thread 6 on the outer side of the upper fixed tube body 1 , and a through groove 7 is opened inside the inclined plate 3 and the through groove 7 is connected with the upper fixed tube body 1 and the lower fixed tube body 2 .

[0017] Specifically, the nut assembly 5 includes a nut body 501 threadably connected to the outer side of the upper fixed tube body 1 , and first rubber pads 502 are fixedly provided on both upper and lower sides of the nut body 501 .

[0018] Specifically, a second rubber pad is provided on a side of the matching ring 4 close to the nut assembly 5 .
