[0030] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0031] Refer to Figures 1 - 4, an embodiment provided by the present utility model: a power system maintenance tool, including a grip 1. Rubber particles are provided on the outer wall of the upper end of the grip 1 to play an anti-slip role. A support block 5 is fixedly connected to the inner wall of the bottom end of the grip 1. The support block 5 is cylindrical in shape and provides support for the sliding of the tool bar 4. The tool bar 4 is slidably connected to the outer wall of the support block 5. The tool bar 4 is used to fix a flat blade 14 and a Phillips screwdriver bit 15. The tool bar 4 can rotate to play a conversion role. A positioning plate 2 is fixedly connected to the outer wall of the tool bar 4. The positioning plate 2 is arc-shaped. When the positioning plate 2 slides into between the fixing block groups 10, the movement of the fixing block groups 10 can drive the positioning plate 2 to move. A slider 6 is slidably connected to the inner wall of the right end of the grip 1. The movement of the slider 6 can drive the tool bar 4 to move through the positioning plate 2 on the tool bar 4, and the length of the tool bar 4 exposed at the bottom end of the grip 1 can be adjusted. A limiting component is provided on the inner wall of the right end of the slider 6, and the limiting component is used for fixing the tool bar 4. A fixing block group 10 is fixedly connected to the outer wall of the left end of the slider 6. The fixing block group 10 drives the movement of the positioning plate 2 and the tool bar 4 through the movement of the slider 6. The fixing block group 10 is composed of two arc-shaped plates. The outer wall of the positioning plate 2 contacts between the two arc-shaped plates of the fixing block group 10. A hollow column 3 is fixedly connected to the outer wall of the right end of the slider 6. The hollow column 3 provides support for the sliding of the elastic block 9 and the limiting ball 13. A through hole is opened on the inner wall of the front end of the hollow column 3. The elastic block 9 is elastically connected to the inner wall of the right end of the slider 6 through a first spring 12. Press the elastic block 9 to the left. By moving the slider 6 downward, the outer wall of the limiting ball 13 is squeezed by the inner wall of the right end of the grip 1 to move the limiting ball 13 back into the hollow column 3, and the slider 6 can be slid. When it moves to a suitable position, release the elastic block 9. The elastic block 9 moves to the right under the action of the elastic force of the first spring 12 to make the limiting ball 13 move forward and be clamped on the inner wall of the right end of the grip 1. The outer wall of the elastic block 9 is slidably connected to the inner wall of the hollow column 3. The front outer wall of the elastic block 9 contacts the rear outer wall of the limiting ball 13. One end of the first spring 12 is fixedly connected to the outer wall of the right end of the slider 6, and the other end of the first spring 12 is fixedly connected to the outer wall of the left end of the elastic block 9. The limiting ball 13 is slidably connected to the inner wall of the front end of the hollow column 3. When the limiting ball 13 is clamped on the inner wall of the right end of the grip 1, the slider 6 can be fixed. When the limiting ball 13 leaves the inner wall of the right end of the grip 1, the fixation of the slider 6 can be released. A tool bit assembly is provided on the outer wall of the tool bar 4, and the tool bit assembly is used for maintenance.

[0032] Referring to Figure 1 , the tool bit assembly includes a flat blade 14. The flat blade 14 is used to turn the corresponding screw during maintenance. The outer wall of the bottom end of the flat blade 14 is fixedly connected to the outer wall of the upper end of the tool bar 4. The outer wall of the bottom end of the tool bar 4 is fixedly connected to a Phillips screwdriver bit 15. The Phillips screwdriver bit 15 is used to turn the corresponding screw during maintenance.

[0033] Referring to Figures 1 - 3, the limiting component includes a plug rod 8. The outer wall of the left end of the plug rod 8 is clamped on the inner wall of the right end of the tool rod 4 to fix the position of the tool rod 4. When the outer wall of the left end of the plug rod 8 leaves the inner wall of the right end of the tool rod 4, the fixation of the tool rod 4 can be released. The outer wall of the left side of the plug rod 8 penetrates and is slidably connected to the inner wall of the right end of the slider 6. The outer wall of the left side of the plug rod 8 penetrates and is slidably connected to the inner wall of the right end of the tool rod 4. The outer wall of the left side of the plug rod 8 is elastically connected to the inner wall of the right end of the slider 6 through a second spring 7. One end of the second spring 7 is fixedly connected to the outer wall of the right end of the slider 6, and the other end of the second spring 7 is fixedly connected to the outer wall of the left side of the plug rod 8. A limiting block 11 is fixedly connected to the outer wall of the upper end of the hollow column 3. The setting of the limiting block 11 limits the position of the plug rod 8, facilitating the pulling of the plug rod 8.

[0034] Working principle: As needed, the fixation of the tool rod 4 is released by moving the plug rod 8. The tool rod 4 is rotated to adjust the required tool bit. After the adjustment is completed, the plug rod 8 is released and clamped on the inner wall of the right end of the tool rod 4 to fix the position of the tool rod 4, and then it can be used. When the exposed length of the tool rod 4 needs to be adjusted, by pressing the elastic block 9 to the left, and moving the slider 6 downward, the inner wall of the right end of the grip 1 squeezes the outer wall of the limiting ball 13 to move the limiting ball 13 back into the hollow column 3, enabling the slider 6 to slide. When it moves to a suitable position, the elastic block 9 is released. The elastic block 9 moves to the right under the elastic force of the first spring 12, causing the limiting ball 13 to move forward and be clamped on the inner wall of the right end of the grip 1, completing the adjustment of the exposed length of the tool rod 4 for convenient use.

[0035] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
