[0022] The present invention will be further described below in conjunction with specific embodiments. The illustrative embodiments and descriptions of the present invention are used to explain the present invention but are not intended to limit the present invention.

[0023] Example 1: A sign for power equipment maintenance, such as Figure 1-Figure 6 As shown, it includes a support frame 1, a lifting rod 2, a fixing ring 3, a pull rod 4, a spring 5 and a fixing component. There are two support frames 1. The support frames 1 are all slidably connected with lifting rods 2. The lifting rods 2 are each provided with a row of positioning holes. The upper part of the support frame 1 is fixedly connected with a fixing ring 3. The fixing ring 3 is slidably connected with a pull rod 4. The pull rods 4 are inserted into adjacent positioning holes. A spring 5 is connected between the pull rods 4 and the adjacent fixing rings 3. By inserting the pull rods 4 into the positioning holes at different positions, the display height of the sign 8 can be adjusted. The support frame 1 is provided with a fixing component, which includes a clamping rod 6, a spring 2 7 and a cross bar 9. Two cross bars 9 are fixedly connected between the two lifting rods 2. Two clamping rods 6 are slidably connected between the two cross bars 9. A spring 2 7 is connected between the cross bar 9 and the clamping rod 6. Under the action of the spring 2 7, the clamping rod 6 can clamp sign boards 8 of different sizes.

[0024] In the initial state, the support frames 1 are all placed on the ground, and then the clamping rod 6 is manually pushed to move to the side away from each other, the spring 27 is compressed, and the identification plate 8 to be placed is placed between the clamping rods 6, and then the clamping rod 6 is released, the spring 27 is restored, and the clamping rods 6 are all moved to the middle, thereby squeezing the identification plate 8 to fix the identification plate 8. The clamping rod 6 and the spring 27 can be used for identification plates 8 of different sizes. By pulling the pull rod 4 and compressing the spring 15, the lifting rod 2 can be moved up and down, and then the pull rod 4 is released and the spring 15 is restored. Under the action of the spring 15, the pull rod 4 is passed through the positioning hole to fix the lifting rod 2. The height of the identification plate 8 can be adjusted by inserting the pull rod 4 into different positioning holes to improve practicality. When the identification plate 8 needs to be put away, the clamping rod 6 is manually pushed to move to the side away from each other, the spring 27 is compressed, and the identification plate 8 can be removed.

[0025] Embodiment 2 is based on embodiment 1, as Figure 7 As shown, a lighting assembly is also included, which includes a lighting lamp 10 and a rotating block 100. The rotating block 100 is rotatably connected to the middle of the upper cross bar 9. A damping is provided at the rotation connection between the rotating block 100 and the cross bar 9. The lighting lamp 10 is threadedly connected to the rotating block 100. By controlling the lighting assembly, the sign 8 can be displayed normally during nighttime maintenance.

[0026] If power maintenance is required at night, the lighting lamp 10 needs to be screwed into the rotating block 100, and the angle of the light can be adjusted by the rotating block 100, so that the sign 8 can also play a warning role at night.

[0027] like Figure 1 , Figure 4 and Figure 5 As shown, it also includes a supporting component, and the fixing component includes a gear 90, a fixing rod 91 and a screw 92. Two gears 90 are rotatably connected to the fixing ring 3, and two adjacent gears 90 are meshed. A fixing rod 91 is fixedly connected to the middle of the gear 90, and a reflective strip is fixedly connected to the fixing rod 91. The fixing ring 3 is threadedly connected with a screw 92, and the screw 92 passes through one of the gears 90 on the same side. The position where the screw 92 passes through the gear 90 is the eccentric position of the gear 90, so that the gear 90 and the fixing rod 91 can be limited. The fixing rod 91 plays a reinforcing role, so that the sign 8 is not easy to tip over.

[0028] In the initial state, the gear 90 is fixed, the fixing rods 91 are in contact with the ground, and the identification plate 8 is fixed. If the fixing rods 91 are to be retracted, the screws 92 must be screwed to disengage the fixing rods 91, and then the gear 90 can be rotated. By rotating the gear 90, two non-adjacent fixing rods 91 are retracted, and by meshing the adjacent gears 90, all four fixing rods 91 are retracted, thereby facilitating the movement of the identification plate 8.

[0029] Those skilled in the art should understand that the above embodiments do not limit the present invention in any form, and any technical solutions obtained by equivalent replacement or equivalent transformation shall fall within the protection scope of the present invention.
