Of course, the base 1 can also be equipped with other similar moving structures and locking structures, which will not be elaborated upon here.

[0036] One end of the support plate 3 is rotatably mounted on the base 1. A support plate receiving groove (not shown in the figure) is provided on the side of the support plate 3 away from the base 1. The rotation angle positioning component 2 is used for positioning the support plate 3 when it is rotated open or closed. A folding structure 5 is provided between the base receiving groove 12 and the support plate 3 to support the support plate 3 when it is rotated open. Simultaneously, a protective component 4 is provided in the support plate receiving groove, and a shock-absorbing structure 6 is provided between the protective component 4 and the support plate receiving groove. In this technical solution, the protective component 4 preferably includes a protective plate 40 and a sponge 41, with the sponge 41 located on the side of the protective plate 40 away from the support plate 3.

A locking member 22 is inserted into the toothed retaining ring 21 for locking and positioning. Specifically, the aforementioned locking member 22 is a locking pin.

[0039] In this utility model, such as Figure 2 and Figure 4 As shown in the illustration, in this embodiment, the folding structure 5 includes a first

[0040] Movable plate 50 and second movable plate 51 are foldably connected. The other end of the first movable plate 50 away from the folding end is hinged to the support plate 3, and the other end of the second movable plate 51 away from the folding end is hinged to the bottom wall of the base receiving groove 12. The first movable plate 50 and the second movable plate 51 are folded and retracted into the base receiving groove 12.

[0041] Furthermore, such as Figure 2 As shown, in order to achieve the smooth connection between the folding structure and the support plate

[0042] To ensure smooth operation and avoid interference with other structures, a support plate groove 31 is provided on the support plate 3, and the other end of the first movable plate 50 away from the folding end is hinged to the bottom wall of the support plate groove 31 via a bearing assembly 9. The support plate groove 31 provides more space for the connecting end of the first movable plate 50, ensuring smooth operation when the support plate 3 is opened or closed. Furthermore, the other end of the second movable plate 51 away from the folding end is hinged to the bottom wall of the base receiving groove 12 via a bearing assembly 11.

[0043] In this utility model, such as Figure 5 and Figure 6 As shown in the figure, in this embodiment, the damping structure 6 includes a fixed

[0044] The system includes a buffer column 60 mounted on the bottom wall of the support plate receiving groove, a first connecting block 61 fixedly mounted on the bottom wall of the support plate receiving groove, a second connecting block fixedly mounted on the bottom wall of the support plate receiving groove, a first connecting rod 62, a second connecting rod, a first slider 63, a first elastic element, a second slider, and a second elastic element. The specific connection structure is as follows: one end of the first connecting rod 62 is hinged to the buffer column 60, and the other end is hinged to the first slider 63; one end of the second connecting rod is hinged to the buffer column 60, and the other end is hinged to the second slider; the buffer column 60 is connected to the corresponding side of the protective plate 40; an elastic element (a third spring 65) is sleeved on the buffer column 40; the first slider 63 is slidably connected to the first connecting block 61; the second slider is slidably connected to the second connecting block; one end of the first elastic element abuts against the first slider 63, and the other end abuts against the inner wall of the first connecting block 61; one end of the second elastic element abuts against the second slider, and the other end abuts against the inner wall of the second connecting block.

[0047] Specifically, such as Figure 5As described above, the guide assembly includes a first guide assembly and a second guide assembly located on opposite sides of the protective assembly. The first guide assembly 7 and the second guide assembly have the same structure. The first guide assembly 7 includes a first guide rod 70 and a first guide sleeve 71. The two ends of the first guide rod 70 are respectively fixed to the top and bottom walls of the support plate receiving groove. One end of the first guide sleeve 71 is sleeved on the first guide rod 70, and the other end is fixed to the corresponding protective assembly 4. The extension direction of the first guide rod 70 is consistent with the reciprocating motion direction of the protective assembly 4.

[0048] Furthermore, to prevent damage to the base and folding structure caused by the support plate 3 being pressed down indefinitely due to external forces when it is closed, a limiting plate can be provided between the base and the support plate.

[0049] To facilitate understanding of the technical solution of this utility model, the working principle is briefly described below:

[0050] In use, the bracket is first moved to the desired destination using the rollers 10. The brake pads lock the rollers 10, allowing the bracket to be placed stably on the ground. Then, the operator releases the locking piece 22, allowing the toothed retaining ring 21 to be in an active state. The support plate 3 is then rotated to be perpendicular to the base 1 and locked using the locking piece 22. The toothed retaining ring 21 is then used to fix the support plate 3. At the same time, the first movable plate 50 and the second movable plate 51 are spliced ​​together to form a straight line to support the support plate 3. Similarly, when the support plate 3 is folded up, the first movable plate 50 and the second movable plate 51 are folded up. After the support plate 3 is unfolded, when the protective plate 40 is subjected to impact force, it moves by being fixed to the guide rod. The retractable buffer column 60 moves to one side. At the same time, under the action of the first connecting rod 62 and the second connecting rod, the first slider 63 and the second slider in the first connecting block 61 and the second connecting block move in the groove and compress the corresponding first spring 64 and the second spring respectively to retract, thus playing a buffering role. The outer side is provided with a sponge 41 to protect people.
