[0014] 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.

[0015] Example 1: A handle 1 is fixed to the bottom of the machine body 3. A lithium battery pack 12 is installed at the bottom of the handle 1. A torque adjustment device 10 is installed at one end of the machine body 3. A cutter head locking sleeve 9 is installed at one end of the torque adjustment device 10. A screwdriver head 8 is fixed at one end of the cutter head locking sleeve 9. A support sleeve 5 is installed on the top of the machine body 3 via a pivot. A telescopic rod 6 is slidably installed inside the support sleeve 5. A lighting component 7 is fixed to one end of the telescopic rod 6. The lighting component 7 includes a collar 701, and a through hole 703 is opened inside the collar 701. An LED light strip 702 is installed on one side of the body 3. A limit component 4 is fixed on one side of the top of the body 3. A spring limit bolt 601 is installed inside the telescopic rod 6. Multiple limit holes 501 are opened at equal intervals on one side of the support sleeve 5. A light switch 11 is installed on one side of the handle 1. A rotary switch 2 is installed on one side of the handle 1. A fixing plate 502 is welded to one side of the support sleeve 5. A positioning screw 503 is connected to the inside of the fixing plate 502 through thread engagement. A threaded hole is opened on the top of the body 3 and is installed in conjunction with the positioning screw 503.

[0016] Specifically, such as Figure 1 , Figure 2 , Figure 3 and Figure 6As shown, since a support sleeve 5 is mounted on the top of the body 3 via a pivot, and a telescopic rod 6 slidably mounted inside the support sleeve 5 has an illumination component 7 fixed at one end, when installing the screwdriver bit 8, one end of the screwdriver bit 8 is passed through the through hole 703 and fixed to the bit locking sleeve 9. Since the illumination component 7 is sleeved on the outside of the screwdriver bit 8, during use, by rotating the positioning screw 503, the bottom end of the positioning screw 503 passes through the fixing plate 502 and is fixedly connected to the threaded hole opened on the top of the body 3, thus fixing the position of the illumination component 7 and preventing the light source from shaking during use. Then, by turning on the LED light strip 702, the light source can be directed towards one end of the screwdriver head 8, thereby accurately illuminating the screw hole or screw and avoiding the occurrence of blind spots due to blocked lighting. Since the telescopic rod 6 is slidably installed inside the support sleeve 5, the spring limit bolt 601 can be retracted into the telescopic rod 6 by pressing it. Then, by pulling the telescopic rod 6, the total length of the support sleeve 5 and the telescopic rod 6 can be adjusted so that the spring limit bolt 601 is locked in the limit hole 501 at the designated position. This allows the user to flexibly adjust the light source illumination angle according to the space size.

[0017] Since a torque adjustment device 10 is installed at one end of the machine body 3, the torque of the cutter head locking sleeve 9 can be adjusted by rotating the torque adjustment device 10. This function is a mature existing technology, so it is not described in detail in the text.

[0018] Example 2: The limiting component 4 includes a first support plate 401 and a second support plate 403. The inside of the first support plate 401 is connected to a threaded rod 406 by threaded engagement, and one end of the threaded rod 406 is connected to a baffle 404 through a rotating seat 402. Two support slide rods 405 are fixed on one side of the baffle 404, and one end of each of the two support slide rods 405 slides through the inside of the first support plate 401.

[0019] Specifically, such as Figure 1 , Figure 3 and Figure 5 As shown, when there is sufficient light and the lighting assembly 7 is not needed, the support sleeve 5 is flipped so that the support sleeve 5 and the telescopic rod 6 are positioned between the first support plate 401 and the second support plate 403. Then, the threaded rod 406 is rotated to move the baffle 404 toward one side of the second support plate 403. When the baffle 404 moves, the two support sliding rods 405 fixed on one side of the baffle 404 will slide along the inside of the first support plate 401, thereby ensuring the stability of the movement of the baffle 404. As the baffle 404 moves, the outer side of the support sleeve 5 or the telescopic rod 6 can be locked between the body 3 and the baffle 404, thereby limiting the lighting assembly 7 and improving the convenience of use.

[0020] Working principle: When the ambient light is insufficient, the lighting component 7 is flipped to one end of the screwdriver head locking sleeve 9. Then, when installing the screwdriver head 8, one end of the screwdriver head 8 is passed through the through hole 703 and fixed to the screwdriver head locking sleeve 9. Since the lighting component 7 is fitted onto the outside of the screwdriver head 8, during use, the bottom end of the positioning screw 503 is fixed by rotating the positioning screw 503, passing through the fixing plate 502 and connecting to the threaded hole on the top of the machine body 3. This fixes the position of the lighting component 7, preventing the light source from flickering during use. Then, by opening... Turning on the LED light strip 702 allows the light source to illuminate one end of the screwdriver head 8, thus accurately illuminating the screw hole or screw and avoiding blind spots caused by blocked light. Then, by pressing the rotary switch 2, the handle 1 can rotate the screwdriver head locking sleeve 9 and the screwdriver head 8 to rotate the screw. When there is sufficient light and the lighting component 7 is not needed, the support sleeve 5 can be flipped to lock the outside of the support sleeve 5 or the telescopic rod 6 between the body 3 and the baffle 404, thereby limiting the lighting component 7 and improving ease of use.

[0021] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
