These tools include but are not limited to wrenches, pliers, screwdrivers, etc., which often become uneven due to various external forces, environmental factors and processing technology limitations during long-term use.

[0003] Power maintenance work is often carried out in complex and harsh environments, such as high temperature, high humidity, dusty substations or outdoor environments. These environmental factors can cause the surface of tools to corrode. For example, a humid environment may cause the metal surface to rust, and the adhesion and friction of dust particles on the tool surface will also affect its flatness. Uneven surfaces not only affect the appearance of the tool, but more importantly, they will reduce the performance of the tool.

[0004] However, the equipment currently on the market for surface treatment of power maintenance tools has certain limitations. Traditional grinding devices are often less versatile and cannot hold power maintenance tools of various shapes and sizes well. Moreover, grinding and leveling devices are often at a fixed height. For maintenance personnel of different heights, a fixed-height grinding table may lead to an uncomfortable operating posture, and long-term work can easily cause fatigue and physical discomfort, thus affecting work efficiency and quality.

[0028] It should be noted that the first motor 6, the electric push rod 8 and the second motor 37 are existing technologies. The specific model specifications need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it is not repeated here.

[0030] Among them, the function of the fixed platform 12 is to block the mobile platforms 5 on both sides to prevent the two mobile platforms 5 from getting too close to each other and causing the components to collide with each other and be damaged. By inserting a specific tool into the rectangular notch 13, the first bidirectional screw 4 can be driven to rotate with the help of the tool, thereby making the mobile platforms 5 approach each other and clamping the power maintenance tool.

[0037] Furthermore, the first fixed plate 20 and the second fixed plate 21 are fixedly connected to the bottom end of the work surface 1, the rotating shaft 22 is rotatably connected to the first fixed plate 20 and the second fixed plate 21 respectively, the first bevel gear 23 is fixedly connected to one end of the rotating shaft 22, and the crank 24 is fixedly connected to the other end of the rotating shaft 22.

[0038] The first fixing plate 20 is arranged at a position close to the crank 24 , and the second fixing plate 21 is arranged at a position close to the first bevel gear 23 ; the first fixing plate 20 and the second fixing plate 21 allow the rotation shaft 22 to run more smoothly.

[0044] The output end of the second motor 37 passes through the outer wall of the U-shaped frame 35 and is fixedly connected to the grinding wheel 36, so that the second motor 37 is started, and the second motor 37 can drive the grinding wheel 36 to rotate, and the grinding wheel 36 can directly grind the surface of the tool.

[0045] Working principle: When using the device, first manually rotate the crank 24, the crank 24 drives the rotating shaft 22 to rotate, the rotating shaft 22 drives the first bevel gear 23 to rotate, the first bevel gear 23 drives the second bevel gear 25 to rotate, the second bevel gear 25 drives the lead screw 26 to rotate, the lead screw 26 pushes the work table 1 up and down under the reaction force, and adjusts it to a suitable height, and then puts the power maintenance tool that needs to be polished on the clamping table 2, and inserts the specific tool into the rectangular notch 13, which can drive the first bidirectional lead screw 4 to rotate with the help of the tool, so that the moving table 5 is close to each other, and then start the first motor 6, the first motor 6 drives the second bidirectional lead screw 15 to rotate, and the second bidirectional lead screw 15 drives the clamping claws 7 on both sides to approach each other, so that the two sides of the tool can be clamped; or the telescopic end of the electric push rod 8 pushes the clamping plate 9 to approach each other, and the two ends of the tool are clamped in the middle.

[0046] The support frame 30 is then manually moved, and the pulley 29 set on the inner wall of the support frame 30 slides on the convex groove 28, which can drive the grinding wheel 36 to move forward and backward.
