[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please refer to Example 1 Figures 1-5 This utility model provides a technical solution:

[0024] A special tool for replacing the cylinder of an aluminum electrolytic cell, which facilitates the disassembly of the hook, includes a fixed base 1. A handle 2 is fixedly provided on one side of the fixed base 1. A through groove 3 is provided on the side of the fixed base 1 away from the handle 2. Grooves 4 are symmetrically provided at the bottom end of the side of the fixed base 1 away from the handle 2. The grooves 4 are symmetrically distributed on the front and rear sides of the through groove 3. A rotating shaft 5 is rotatably provided on the inner wall of the top of each groove 4. A sleeve 6 matching the groove 4 is connected to the bottom end of each rotating shaft 5. An internal hexagonal groove is provided at the bottom end of each sleeve 6.

[0025] Specifically, such as Figures 1-5As shown, the fixed base 1 has a cavity 7 on the side near the handle 2. A second rotating shaft 8 is rotatably mounted on both the front and rear inner walls of the cavity 7. A sprocket 9 is fixedly fitted onto the upper part of each rotating shaft 5, and a second sprocket 10 is fixedly fitted onto the upper part of each rotating shaft 8. Each sprocket 9 and the adjacent sprocket 10 are connected by a chain 11. A motor 12 is fixedly mounted on the bottom inner wall of the cavity 7, and multiple sprockets 13 are fixedly mounted on the output end of the motor 12. Each of the rotating shafts 2 and 8 is fixedly fitted with a sprocket 4 and 14. The sprocket 3 and 13 are connected to the adjacent sprocket 4 and 14 by a chain 2 and 15. The motor 12 drives the sprocket 3 and 13 to rotate, which in turn drives the sprocket 4 and 14 to rotate via the chain 2 and 15. At this time, the sprocket 4 and 14 will drive the rotating shaft 2 and 8 to rotate. The rotating shaft 2 and 8 will drive the sprocket 2 and 10 to rotate. The sprocket 2 and 10 can drive the sprocket 1 and 9 to rotate via the chain 1 and 11. The sprocket 1 and 9 can drive the rotating shaft 1 and 6 and 6 to rotate.

[0026] Specifically, such as Figures 1-5 As shown, a control switch 16 is provided at the top of the handle 2. The control switch 16 is electrically connected to the motor 12. Anti-slip texture is provided around the outer wall of the handle 2. The start and stop of the motor 12 can be controlled by the control switch 16. By setting the anti-slip texture, the stability of the user when holding the device can be improved.

[0027] Specifically, such as Figures 1-5 As shown, the lower part of the rotating shaft 5 is provided with threads, and the top of the sleeve 6 is provided with a threaded groove 17 that matches the rotating shaft 5. By providing the threaded groove 17, the rotating shaft 5 can be screwed into the threaded groove 17, which facilitates the disassembly, assembly and replacement of the sleeve 6.

[0028] Please refer to Example 2 Figures 1-5 The difference between this embodiment and embodiment 1 is that the sleeve 6 is made of neodymium iron boron magnet material. By using neodymium iron boron magnet material, the sleeve 6 can attract the nut, thereby improving the convenience of using the device.

[0029] The working principle of this utility model is as follows: When in use, the fixing base 1 is placed in a suitable position, at which time the hook is located in the through groove 3, and the nut and part of the stud are inserted into the sleeve 6. The sleeve 6 can limit the nut. Then, the motor 12 drives the sprocket 3 13 to rotate, which in turn drives the sprocket 4 14 to rotate through the chain 2 15. At this time, the sprocket 4 14 drives the rotating shaft 2 8 to rotate, which in turn drives the sprocket 2 10 to rotate. The sprocket 2 10 drives the sprocket 19 to rotate through the chain 1 11. The sprocket 19 drives the rotating shaft 5 and the sleeve 6 to rotate, which in turn drives the nut to rotate through the sleeve 6. This makes it easy to loosen and remove the nut. The sleeve 6 is made of neodymium iron boron magnet material, which can attract the nut and improve the convenience of the device. By setting the threaded groove 17, the rotating shaft 5 can be screwed into the threaded groove 17, which makes it easy to disassemble and replace the sleeve 6.
