[0025] In order to more clearly illustrate the technical solution of the utility model, the following will briefly introduce the drawings required for the description. Obviously, the drawings described below are only some embodiments of the utility model. For ordinary technicians in this field, other embodiments can be obtained based on these drawings without creative work. In order to facilitate the understanding of the utility model, the following will be combined with the drawings and specific embodiments to explain the utility model in more detail.

[0026] It should be noted that when an element is described as being "fixed to" another element, it may be directly on the other element, or one or more centered elements may exist therebetween. When an element is described as being "connected to" another element, it may be directly connected to the other element, or one or more centered elements may exist therebetween. The terms "upper", "lower", "inner", "outer", "bottom", "left", "right", etc. used in this specification indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention. In addition, the terms "first", "second", "third", etc., etc. are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0027] like Figure 2 , Figure 3 As shown:

[0028] The upper upright 1 is a tube body, and a guide member 3 is fixedly installed at the bottom of the upper upright 1. The guide member 3 is a cylinder and can be made entirely of rubber material. The upper part of the guide member 3 is provided with an annular protrusion 31 made of rubber material, and the lower part is provided with three block-shaped protrusions 32 made of rubber material that are evenly distributed around the circumference.

[0029] The bottom end of the upper upright 1 is provided with three notches 12 evenly distributed around the circumference.

[0030] When the guide member 3 is inserted into the bottom of the upper upright 1, the annular protrusion 31 is tightly against the inner wall of the upper upright 1, and due to the elasticity of the rubber material, the guide member 3 is firmly installed at the bottom of the upper upright 1, and the three block protrusions 32 of the guide member 3 are respectively inserted into the three notches 12 of the upper upright 1, thus preventing the guide member 3 from rotating.

[0031] like Figure 2 , Figure 4 As shown:

[0032] An annular groove 21 is provided at the top end of the base upright 2, and a rubber anti-skid ring 4 is embedded in the annular groove 21. The inner wall of the anti-skid ring 4 is provided with three circumferentially evenly distributed notches 42 for the three block-shaped protrusions 32 to pass through.

[0033] like Figure 1 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 As shown:

[0034] Insert the upper upright 1 into the base upright 2, and the three block-shaped protrusions 32 enter the base upright 2 after passing through the three notches 42. The three block-shaped protrusions 32 are tightly pressed against the inner wall of the tube of the base upright 2, and the anti-slip ring 4 is tightly pressed against the outer wall of the upper upright 1. The elasticity of the rubber material enables the above two tight-contact structures to be realized and the upper upright 1 can be inserted into the base upright 2.

[0035] After being inserted to a suitable height, the pin 5 passes through the through hole of the base upright 2 and the through hole 11 of the upper upright 1 to connect the two, thereby fixing the height of the upper upright 1.

[0036] Since the block-shaped protrusion 32 is pressed against the inner wall of the base upright 2 and the anti-slip ring 4 is pressed against the outer wall of the upper upright 1 , the upper and lower supporting structures can ensure that the upper upright 1 of the sleeve structure does not shake in the base upright 2 .

[0037] The various embodiments in the specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments, and the same and similar parts between the various embodiments can be referred to each other. The above description of the disclosed embodiments enables professionals and technicians in this field to implement or use the utility model. Various modifications to these embodiments will be obvious to professionals and technicians in this field, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the utility model. Therefore, the utility model will not be limited to the embodiments shown herein, but will conform to the widest range consistent with the principles and novel features disclosed herein.
