Techniques, methods, and apparatus known to those of ordinary skill in the relevant art may not be discussed in detail but are intended to be part of the specification where appropriate.

In all examples shown and discussed herein, any particular value should be construed as merely illustrative, and not limiting. Thus, other examples of the exemplary embodiments may have different values.

It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, further discussion thereof is not required in subsequent figures.

According to fig. 1 to 3, the utility model provides a screwdriver for electrical maintenance, including screw rod 1 and handle 5, the one end of screw rod 1 is equipped with screwdriver bit 2, and the one end of keeping away from screwdriver bit 2 on screw rod 1 is equipped with spliced pole 4.

The interior of the handle 5 is provided with an inner cavity, the connecting column 4 penetrates through the end face of the handle 5 and extends into the inner cavity of the handle 5, and the middle part of the connecting column 4 is provided with an adjusting groove 6 along the length direction of the connecting column 4. An adjusting block which is vertical to the adjusting groove 6 is connected in the adjusting groove 6 through threads, and the adjusting block penetrates through the side wall of the handle 5 and is connected with an adjusting knob 7. In practice, the extension or shortening of the connecting column 4 towards the screwdriver is realized by means of the matching of the adjusting block and the adjusting groove 6, and the specific matching mode can be a mode of matching threads and gear teeth.

Further, the screw rod 1 and the screwdriver head 2 are integrally formed, and one end, far away from the screw rod 1, of the screwdriver head 2 is arranged in a conical mode. Because the utility model discloses a screw rod 1 adjustable length does not need the screwdriver head 2 of often changing the length difference, so screw rod 1 can take shape with screwdriver head 2 integration, saves production processes.

Further, a fixing block 3 is arranged at the joint of the screw rod 1 and the connecting column 4, and the fixing block 3 is positioned outside the handle 5. During implementation, the length of the inner cavity of the handle 5 is fixed, the length of the connecting column 4 which can extend into the inner cavity of the handle 5 is also fixed, and the fixing block 3 prevents the connecting column 4 from being damaged or the adjusting block from being damaged due to the fact that the adjusting knob 7 is continuously rotated after the connecting column 4 completely enters the inner cavity of the handle 5.

Furthermore, a connecting block 13 is further arranged at one end of the connecting column 4 far away from the screw rod 1, and the connecting block 13 penetrates through the other end face of the handle 5 and is provided with a hanging hole 14. The utility model discloses under the condition of not using, can hang on the wall body through hanging hole 14, be convenient for use next time and find easily.

Furthermore, one end of the adjusting block, which is far away from the adjusting knob 7, also penetrates through the side wall of the handle 5 and is sleeved with a fixing nut. When the adjusting knob 7 adjusts the length of the connecting column 4 to a proper position, a certain acting force is generated between the screwdriver and the bolt, and in order to prevent the adjusting knob 7 from rotating under the acting force, the relation between the adjusting block and the handle 5 can be fixed through the fixing nut, so that the use is convenient.

Furthermore, the whole handle 5 is cylindrical, and the surface of the handle 5 is provided with anti-skid grooves which are inosculated with the palm of a person, so that the handle is convenient for an operator to hold.

Furthermore, the end face of the inner cavity of the handle 5, which is close to the joint with the connecting column 4, is also provided with a fixed disc 11, a rubber ring 12 is arranged inside the fixed disc 11, and the rubber ring 12 is sleeved on the surface of the connecting column 4. The fixed disc 11 and the rubber ring 12 can limit and support one end of the connecting column 4, and a large gap is prevented from being formed at the joint of the fixed disc and the handle 5.

Furthermore, a positioning block 8 is arranged on the side wall of the inner cavity of the handle 5, and a sliding groove 9 is arranged on the inner side wall of the positioning block 8; the outer side wall of the connecting column 4 is provided with a limiting block 10, and the limiting block 10 slides in the sliding groove 9. Because the connecting column 4 needs to slide in the inner cavity of the handle 5, and the diameter of the connecting column 4 is smaller than that of the inner cavity, the connecting column 4 needs to be provided with a limiting block 10, so that the connecting column 4 can only slide along the length direction of the handle 5. In addition, a groove is formed in the positioning block 8, the limiting block 10 slides in the sliding groove 9, and the length of the sliding groove 9 is the adjustable length of the connecting column 4.

Furthermore, the positioning block 8, the limiting block 10, the connecting column 4 and the handle 5 have concentric circle structures. The cylindrical structure is more convenient for assembly and production.

Furthermore, the adjusting block is positioned on the adjusting groove 6 between the connecting positions of the positioning block 8, the connecting column 4 and the handle 5, so that the influence of the adjusting block on the sliding between the limiting block 10 and the sliding groove 9 on the positioning block 8 can be avoided.

When the length of the screw rod 1 needs to be adjusted in the using process, the adjusting knob 7 is manually and reversely unscrewed, the adjusting block is driven to move out of the adjusting groove 6, the left end of the screw rod 1 can be manually moved towards the screwdriver head 2, and the adjusting knob 7 is screwed again after the length is adjusted properly (or a fixing nut is arranged at the other end of the adjusting block and fixed in a mode of screwing the fixing nut); and the screwdriver can be hung on a wall through the hanging hole 14 when not in use, so that the screwdriver does not occupy space and is convenient to take when being used next time.

Although certain specific embodiments of the present invention have been described in detail by way of example, it should be understood by those skilled in the art that the foregoing examples are for purposes of illustration only and are not intended to limit the scope of the invention. It will be appreciated by those skilled in the art that modifications may be made to the above embodiments without departing from the scope and spirit of the invention.
