The upper tube is slidably connected to the railing through the first circular hole, and the sliding tube is slidably connected to the railing through the second circular hole.

[0006] Furthermore, a slot is provided at the upper end of the sliding tube located below the inner clamping plate and at the lower end located above the inner clamping plate, and the slot is slidably connected to a positioning column.

[0007] Furthermore, the outer walls of the lower tube and the upper tube are both provided with slots, and the slots are adapted to the positioning posts.

[0008] Furthermore, the outer walls of the first circular holes on the lower tube and the upper tube are both provided with an annular outer ring sleeve.

[0009] Furthermore, an annular inner ring sleeve is provided on the inner wall of the second circular hole.

[0010] Furthermore, fluorescent rings are sprayed on the railings, and the fluorescent rings are evenly spaced.

[0011] Furthermore, the positioning column is T-shaped.

[0012] The beneficial effects of the utility model are:

[0013] Through the mutual cooperation between the lower tube, upper tube and sliding tube, outer clamping plate, inner clamping plate, clamping groove and positioning column, when the upper tube is pulled upward, the outer clamping plate pulls the inner clamping plate and then drives the sliding tube to move together until the inner clamping plate at the lower end of the sliding tube contacts the inner clamping plate at the upper end of the lower tube, and then the positioning column is inserted into the clamping groove to raise the height of the upper tube, and then the railing is inserted into the first circular hole and the second circular hole to complete the assembly.

[0020] The present invention will now be described in further detail with reference to the accompanying drawings, which are simplified schematic diagrams that illustrate the basic structure of the present invention in a schematic manner.

[0021] like Figures 1 to 4As shown, the utility model provides a maintenance protection device, including a lower tube 1, the lower tube 1 is slidably connected to the railing 304 through the first circular hole 3, the lower tube 1 is slidably connected to the upper tube 101 through the sliding tube 102, the upper end of the inner wall of the lower tube 1 and the upper tube 101 and the lower end of the inner wall are all provided with an outer card plate 2, the upper and lower ends of the outer wall of the sliding tube 102 are all provided with an inner card plate 201, when the upper tube 101 is pulled upward, the sliding tube 102 is driven to slide together through the outer card plate 2, the upper tube 101 is slidably connected to the railing 304 through the first circular hole 3, the sliding tube 102 is slidably connected to the railing 304 through the second circular hole 302, and the sliding tube 102 is A slot 202 is provided at the upper end below the inner card plate 201 and the lower end above the inner card plate 201. The slot 202 is slidably connected to a positioning column 203. When the slide tube 102 slides to the inner card plate 201 at the lower end and contacts the outer card plate 2 at the upper end of the lower tube 1, the positioning column 203 is inserted into the slot 202 to fix the upper tube 101 and the slide tube 102. The outer walls of the lower tube 1 and the upper tube 101 are both provided with a slot 204, which is adapted to the positioning column 203. When the positioning column 203 is not needed, the positioning column 203 can be inserted into the slot 204. The shape of the positioning column 203 is T-shaped.
