The outer side of the handle 1 is connected to a top cover 17 via a pivot. A shaft 18 is connected inside the internal groove 16. A bushing 19 is fitted onto the outer side of the shaft 18. A screwdriver 22 is connected to the outer side of the bushing 19. A lower seat 24 is provided inside the handle 1. The screwdriver 22 is installed inside the lower seat 24. An upper seat 23 is provided on the top of the lower seat 24. A mounting screw 25 is provided inside the upper seat 23, and the mounting screw 25 is threadedly connected to the lower seat 24. Specifically, by providing an internal hexagonal sleeve 2 and a first internal hexagonal screw sleeve 4 on the outer side of the handle 1... The equipment includes a screw insert 3, a second hex socket screw insert 4, an upper body 23 and a lower body 24, and a screwdriver 22. When the operator needs to use the screwdriver 22, the top cover 17 is opened in the reverse direction, and the screwdriver 22 is rotated on the inside. The screwdriver 22 is then installed on the inside of the upper body 23 and the lower body 24 using a fastener. This allows the operator to hold the handle 1 and perform maintenance work on the equipment by rotating the screwdriver 22. When the first hex socket screw insert 3 needs to be used, the fastener is tightened to install it on the inside of the hex socket insert 2. When the second hex socket screw insert 4 needs to be used, the fastener is removed again and installed on the inside of the first hex socket screw insert 3. The operator can choose the necessary tools for maintenance according to actual needs. Moreover, the operator does not need to carry multiple tools during the maintenance process, making it more convenient and simple to operate.

[0027] In this embodiment, the inner side of the hexagon socket sleeve 2 is provided with a magnetic absorbing piece 5, and the outer side of the first hexagon socket sleeve 3 is provided with a metal piece 6. The magnetic absorbing piece 5 attracts the metal piece 6 by magnetic force. The outer side of the second hexagon socket sleeve 4 is provided with a retaining block 14. The inner side of the first hexagon socket sleeve 3 is provided with a retaining groove 15, and the retaining block 14 is embedded in the retaining groove 15. The outer side of the hexagon socket sleeve 2 is provided with a mounting plate 29, which is symmetrically distributed. The outer side of the mounting plate 29 is provided with a reinforcing ring 30. The inner side of the mounting plate 29 is provided with a first through hole 7 and a second through hole 8. The first through hole 7 is provided with a fastening screw 10, and the second through hole 8 is provided with a locking screw 13. The inner side of the first hexagon socket sleeve 3 is provided with a through hole 11, and the locking screw 13 is provided with a through hole 11. Inside the through hole, a first threaded groove 9 is formed on the outer side of the first internal hexagonal socket sleeve 3, and a second threaded groove 12 is formed on the outer side of the second internal hexagonal socket sleeve 4. The fastening screw 10 is threadedly connected to the first threaded groove 9, and the locking screw 13 is threadedly connected to the second threaded groove 12. Specifically, by installing structures such as the metal plate 6 and magnetic groove, and the locking block 14 and locking slot 15, the first internal hexagonal socket sleeve 3 is pinched and magnetically attracted to be initially installed on the inner side of the internal hexagonal socket sleeve 2. Alternatively, the second internal hexagonal socket sleeve 4 is pinched and the outer locking block 14 is embedded in the locking slot 15, which can be initially installed on the side of the first internal hexagonal socket screw. Subsequently, the outer fastener is tightened to form a threaded connection, which can then be fixed.

[0028] In this embodiment, a support rod 20 is provided inside the inner groove 16, and a clamping ring 21 is provided at the top of the support rod 20. There are two sets of clamping rings 21. A screwdriver 22 is installed on the inner side of the clamping ring 21. A circular hole 26 is opened inside the upper seat 23, and a half hole 28 is opened on the inner side of the upper seat 23. A half hole 28 is opened on the inner side of the lower seat 24, and a threaded hole 27 is opened on the side of the lower seat 24. A mounting screw 25 passes through the circular hole 26 and is threaded into the threaded hole 27. Specifically, since the structure includes an upper body 23, a lower body 24, a circular hole 26, a threaded groove, and a mounting screw 25, when the screwdriver 22 rotates to the inside of the lower body 24, the operator removes the upper body 23 and installs it on top of the lower body 24. Subsequently, the mounting screw 25 is removed, first passing through the circular hole 26, and then threaded into the threaded hole 27 inside the lower body 24. In this way, the screwdriver 22 can be removed from the handle 1, and the handle 1 can be held for subsequent use.

[0029] Working Principle: When using the maintenance tool for the primary equipment of this substation, the user first assembles a modular maintenance tool to save physical effort and facilitate tool carrying. Before use, the operator first rotates the top cover 17 in reverse, then pinches the screwdriver 22 on the side of the bushing 19 and rotates it around the shaft 18, thus installing it inside the lower seat 24. Next, the upper seat 23 is removed and installed on top of the lower seat 24. The mounting screw 25 is passed through the circular hole 26, and the mounting screw 25 is screwed into the threaded hole 27 for threaded connection, allowing the screwdriver 22 to be used normally. The operator then rotates the top cover 17 in reverse again. Next, the first hexagon socket sleeve 3 and the second hexagon socket sleeve 4 are removed in sequence. The first hexagon socket sleeve 3 is removed first, and the outer metal piece 6 is attracted and connected to the magnetic piece 5. Then, the fastening screw 10 is removed, passes through the interior of the mounting plate 29, and is threaded into the first threaded groove 9, thus installing and fixing the first hexagon socket sleeve 3 to the hexagon socket. Inside sleeve 2, then remove the second hex socket sleeve 4, insert the side retaining block 14 into the retaining groove 15 on the side of the first hex socket sleeve 3, and then take out the locking screw 13 to pass through the mounting plate 29 and the inside of the first hex socket sleeve 3, and connect it with the second threaded groove 12. In this way, the second hex socket sleeve 4 can be installed inside the hex socket sleeve 2. Finally, the staff only needs to select the tool to use according to the actual needs. When using screwdriver 22, pinch the handle 1 and turn the hex socket sleeve 2 outward. When it is necessary to use the second hex socket sleeve 4 to disassemble the equipment inside the substation, simply put it on the outside of the part to be disassembled. When it is necessary to use the first hex socket sleeve 3, turn the locking screw 13 in the opposite direction to remove the second hex socket sleeve 4 from the inside, and then hold the handle to put the first hex socket sleeve 3 on the outside of the metal part to be disassembled. In this way, the first hex socket sleeve 3 can be turned in the opposite direction to disassemble the metal part, which is convenient for the staff to carry out equipment maintenance work.
