The outer sleeve 41 is a square tube, which is sleeved on the outside of the vertical support frame 3 and has threaded holes on the side. After the bolts are tightened, the friction between the bolt ends and the side of the vertical support frame 3 is used to limit the position.

[0028] The horizontal support plate 42 is arranged horizontally, and one end is fixedly arranged outside the outer sleeve 41. The horizontal adjustment assembly 5 includes a horizontal rod 51 and a connecting bolt. Threaded holes are arranged on the horizontal support plate 42 and the horizontal rod 51. The connecting bolt is used to realize a movable and limitable connection of the horizontal rod 51 relative to the horizontal support plate 42. Since the horizontal position can be adjusted by moving the chassis assembly 1, the horizontal support plate 42 and the horizontal rod 51 generally do not need to be adjusted frequently.

[0029] As attached Figure 6 As shown, the rotating plate assembly 6 includes a rotating plate 61, at least one limiting plate 62, and two relatively arranged protruding tubes 611 are arranged on one side of the rotating plate 61, and a through hole is arranged on the protruding tube 611, which is rotatably connected to the end of the horizontal rod 51 through a pin shaft, wherein at least one protruding tube 611 is longer and has a limiting through hole arranged at the end, and the limiting plate 62 is fixedly arranged on the side of the end of the horizontal rod 51, located between the side of the horizontal rod 51 and the protruding tube 611, and the limiting through holes distributed in a ring array are arranged on the limiting plate 62, and the fixing of the position of the protruding tube 611 and the limiting plate 62 is achieved by a bolt structure.

A through hole is arranged at the position of the rubber square tube pad 431 corresponding to the threaded hole on the side of the outer set 41. An inner friction plate 432 is arranged inside the side of the rubber square tube pad 431 corresponding to the threaded hole on the side of the outer set 41. The inner friction plate 432 is a metal plate. A threaded blind hole is arranged at the position corresponding to the through hole of the rubber square tube pad 431. An inner buffer pad 433 is arranged inside the rubber square tube pad 431. The thickness of the upper part of the inner buffer pad 43 is less than that of the lower part.

[0033] A groove 4311 is provided on the inner side of the rubber square tube pad 431 , and the inner friction plate 432 can be inserted into the groove 4311 .

[0034] Attached Figure 4 In the figure, in order to facilitate the display of the inner friction plate 432 and the inner buffer pad 433, they are placed on the outside of the rubber square tube pad 431, and should actually be arranged in the groove 4311 on the inner side of the rubber square tube pad 431.

[0035] The surface of the vertical support frame 3 is provided with an array of groove textures to increase friction.

[0036] In this embodiment, the rubber square tube pad 431 can provide not only buffering but also friction. In addition, the vertical support frame 3 is tilted, so when the limit bolt is not tightened, the height adjustment assembly 4 can be ensured not to slide downward. When in use, the bolt passes through the threaded hole on the side of the outer sleeve 41, the through hole of the rubber square tube pad 431, and the threaded blind hole of the inner friction plate 432. By tightening, the inner friction plate 432 can be in close contact with the vertical support frame 3 to achieve limit. The thin upper and thick lower setting of the inner buffer pad 433 can play the role of a wedge to a certain extent.

[0037] The lower part of the rubber square tube pad 431 is provided with a protruding ring 4312 , the thickness of which is greater than the outer sleeve 41 , so as to prevent the outer sleeve 41 from sliding off the rubber square tube pad 431 .

[0038] Attached Figure 5 Another embodiment of a height adjustment component 4 is provided, wherein the height adjustment component 4 further includes an inner sleeve 43 and an inner tube component 44 .

[0039] The inner sleeve 43 is a rubber square tube pad in a square tube shape, which is arranged between the outer sleeve 41 and the vertical support frame 3. A through hole is arranged at the position of the inner sleeve 43 corresponding to the threaded hole on the side of the outer sleeve 41. The inner sleeve 43 is thin at the top and thick at the bottom, which can play the role of a wedge to a certain extent. A protruding ring 4312 is arranged at the bottom of the inner sleeve 43, and its thickness is greater than that of the outer sleeve 41 to prevent the outer sleeve 41 from sliding off the inner sleeve 43.

[0040] The vertical support frame 3 is provided with an upper through slot 31 on the side corresponding to the threaded hole on the side of the outer sleeve 41. The inner tube 44 is a rectangular metal block that can be slidably embedded in the vertical support frame 3. A threaded hole is provided in the area corresponding to the threaded hole on the side of the outer sleeve 41.

[0041] When in use, the bolts pass through the threaded holes on the side of the outer sleeve 41, the through holes of the rubber square tube pad 431, and the slots 31 of the vertical support frame 3. The threaded holes of the inner tube part 44 can be tightened to achieve close contact between the inner tube part 44 and the inner wall of the vertical support frame 3, and between the outer sleeve 41 and the rubber square tube pad 431 and the outer wall of the vertical support frame 3.

[0042] It should be noted that, unless otherwise clearly specified and limited, the terms such as "install", "connect", "connect", "fix", "set" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral one; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.
