[0016] 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.

[0017] Please see Figure 1-3 This utility model provides a technical solution: a screwdriver for power grid maintenance, including a handle 1 and a plurality of screwdriver heads 2. The upper wall of the handle 1 is provided with an installation groove, and a plug 3 is fixedly installed in the installation groove. The inner diameter cross-section of the plug 3 is a regular hexagonal structure. The cross-section of the screwdriver heads 2 is a regular hexagonal structure. The upper end of the plug 3 is exposed outside the handle 1. A limiting component is provided at the upper end of the plug 3. A limiting groove 4 is provided on the screwdriver heads 2. A plurality of bearing grooves 5 are provided on the lower wall of the handle 1. The distance from the center of the plurality of bearing grooves 5 to the center of the handle 1 is equal. An external thread is provided on the lower outer wall of the handle 1. A cover plate 6 is screwed onto the lower wall of the handle 1.

[0018] Several screwdriver bits 2 are stored in several support slots 5. When the screwdriver bits 2 are needed, the cover plate 6 is unscrewed, the screwdriver bits 2 are taken out from the support slots 5, the cover plate 6 is tightened, the screwdriver bits 2 are inserted into the insert 3, and the screwdriver bits 2 are limited by the limiting component. Since several limiting slots 4 are opened on the screwdriver bits 2, the length of the screwdriver bits 2 exposed in the insert 3 can be adjusted by the cooperation of the limiting component with the limiting slots 4.

[0019] Furthermore, the limiting component includes a baffle 7, which is fixedly installed on the upper part of the outer wall of the insert 3. A limiting ring 8 is fitted on the insert 3. A first spring 9 is fixedly installed between the lower wall of the limiting ring 8 and the upper wall of the handle 1. The first spring 9 is fitted on the insert 3. An inner cavity 10 is opened on the wall of the insert 3. A through hole 11 is opened on one side of the inner cavity 10. A guide hole 12 is opened on the other side of the inner cavity 10. A second spring 13 is fixedly installed on the side wall of the inner cavity 10. A ball 14 is fixedly installed on the other end of the second spring 13. One end of the ball 14 is exposed in the through hole 11. A limiting rod 15 is fixed on the other end of the ball 14. The limiting rod 15 passes through the guide hole 12.

[0020] Pressing down the limiting ring 8 compresses the first spring 9, causing the limiting ring 8 to separate from the ball 14. A portion of the ball 14 is exposed through the through hole 11. At this time, the second spring 13 is pushed to the ball 14, causing the limiting rod 15 to move into the guide hole 12. Then, the screwdriver head 2 is inserted into the slot, releasing the limiting ring 8, causing the limiting ring 8 to spring back. The limiting ring 8 pushes the ball 14, which compresses the second spring 13. The ball 14 pushes the limiting rod 15, causing the limiting rod 15 to insert into the limiting groove 4 and fix the screwdriver head 2.

[0021] Furthermore, a force-bearing plate 16 is fixedly installed on the outer wall of the limiting ring 8, which facilitates the operator to pull the limiting ring 8 under force.

[0022] Furthermore, the limiting rod 15 is matched with the limiting groove 4.

[0023] Furthermore, the cover plate 6 has a mating groove, and the inner wall of the mating groove has an internal thread. The cover plate 6 is connected to the outer wall of the handle 1 by the internal thread in the mating groove.

[0024] Furthermore, an insulating rubber sleeve 17 is fixedly installed on the outer wall of the handle 1.

[0025] Its detailed connection method is a well-known technology in this field. The following mainly introduces the working principle and process, and the specific work is as follows.

[0026] Example: As shown in the accompanying drawings, during use, several screwdriver heads 2 are stored in several bearing grooves 5. When the screwdriver heads 2 are needed, the cover plate 6 is unscrewed, the screwdriver heads 2 are taken out from the bearing grooves 5, and the cover plate 6 is tightened. The screwdriver heads 2 are then inserted into the insert 3, and the limiting ring 8 is pressed down, causing the first spring 9 to compress, thus separating the limiting ring 8 from the ball 14. A portion of the ball 14 is exposed through the through hole 11. At this time, the second spring 13 is extended to the ball 14, causing... The limiting rod 15 moves into the guide hole 12. At this time, the screwdriver head 2 is inserted into the slot, the limiting ring 8 is released, and the limiting ring 8 rebounds. The limiting ring 8 pushes the ball 14, the ball 14 compresses the second spring 13, and the ball 14 pushes the limiting rod 15, so that the limiting rod 15 is inserted into the limiting groove 4 to fix the screwdriver head 2. Since several limiting grooves 4 are opened on the screwdriver head 2, the length of the screwdriver head 2 exposed outside the insert 3 can be adjusted by the cooperation of the limiting component with the limiting groove 4.

[0027] It should be noted that in this paper, relational terms such as first and second are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations.
