[0029] This utility model provides a repair screwdriver with a detachable protective structure, such as Figures 1-6 As shown, the device includes: a screwdriver bit 4, a handle 1, and a collector. One end of the screwdriver bit 4 is the working end, which is used to insert into the slot or recess of a screw head and drive the screw to rotate to loosen it. The handle 1 is used to connect to the end of the screwdriver bit 4 away from the working end and can drive the screwdriver bit 4 to rotate. The collector is detachably sleeved and fixed to the end of the handle 1 near the screwdriver bit 4. A collection station is provided on the side of the collector near the screwdriver bit 4. The collection station is used to receive fallen screws. By setting up a detachable collector, screws that may fall can be effectively collected when removing screws, preventing screw loss and improving work efficiency.

[0030] In a preferred embodiment, the collecting component includes a first protective cover 7, a second protective cover 6, a positioning shaft 5, and a first locking member. The positioning shaft 5 passes through the handle 1 and is fixedly connected to the handle 1. The first protective cover 7 is provided with a first snap-fit ​​hole, and the second protective cover 6 is provided with a second snap-fit ​​hole. The two ends of the positioning shaft 5 extending out of the handle 1 are respectively inserted into the first snap-fit ​​hole and the second snap-fit ​​hole to position the first protective cover 7 and the second protective cover 6 in the axial direction of the handle 1. The first locking member is used to lock the first protective cover 7 and the second protective cover 6 sleeved on the handle 1. The first protective cover 7 is provided with a first receiving cavity, and the second protective cover 6 is provided with a second receiving cavity. The first receiving cavity and the second receiving cavity after locking form a collecting station, which can conveniently position and lock the first protective cover 7 and the second protective cover 6, ensure the stability of the collecting station, and effectively prevent screws from falling off and being lost.

[0031] In a preferred embodiment, a first connecting plate is provided at both ends of the first protective cover 7, and a second connecting plate is provided at both ends of the second protective cover 6. A first locking member is used to detachably fix the first connecting plate and the second connecting plate on the same side. By setting the connecting plate and using the first locking member to connect them, the connection between the first protective cover 7 and the second protective cover 6 is more secure, and it is also easier to disassemble and install.

[0032] In a preferred embodiment, the first locking member includes a snap-fit ​​side plate 8, a limiting plate, a guide rod 9, and an elastic member. The snap-fit ​​side plate 8 is vertically fixedly connected to the side of the second connecting plate away from the first connecting plate. One end of the guide rod 9 passes through the limiting plate and is vertically fixedly connected to the snap-fit ​​side plate 8. The limiting plate slides along the guide rod 9. One end of the elastic member is fixedly connected to the guide rod 9, and the other end is used to fixally connect to the limiting plate so that the end of the limiting plate snaps onto the side of the first connecting plate away from the second connecting plate. The limiting plate is an L-shaped limiting block 11, and the corner of the L-shaped limiting block 11 is used to snap-fit ​​into the first connecting plate. The elastic member is a support spring 10. The first locking member has a simple structure, is easy to operate, and can quickly lock and unlock the first protective cover 7 and the second protective cover 6, improving work efficiency and facilitating carrying after disassembly.

[0033] In a preferred embodiment, the maintenance screwdriver with a detachable protective structure also includes a snap-fit ​​bottom shell 2, which is fixedly connected to the end of the handle 1 near the bit 4. The bit 4 is slidably connected to the snap-fit ​​bottom shell 2 and can maintain its position after sliding. The snap-fit ​​bottom shell 2 allows the bit 4 to slide and maintain its position, making it convenient to adjust the length of the screwdriver to adapt to different working scenarios.

[0034] In a preferred embodiment, a second locking member 3 is also included. The snap-fit ​​bottom shell 2 is provided with a limiting groove 16, and a guide block 15 is provided at the end of the bit 4 away from the working end. The guide block 15 is slidably connected in the limiting groove 16 and can restrict relative rotation between the bit 4 and the snap-fit ​​bottom shell 2. The second locking member is used to lock the slid bit 4 and the snap-fit ​​bottom shell 2 in the axial direction. Through the cooperation of the guide block 15 and the limiting groove 16, relative rotation between the bit 4 and the snap-fit ​​bottom shell 2 can be effectively prevented, thereby improving the stability and reliability of the screwdriver.

[0035] In a preferred embodiment, the second locking member 3 includes a locking ring 301, a threaded ring 302, an adjusting nut 303, and a clamping block 304. The threaded ring 302 is fixedly connected to the end of the snap-fit ​​base 2 away from the handle 1. The locking ring 301 is fixedly connected to the side of the locking ring 301 away from the snap-fit ​​base 2. The adjusting nut 303 is used to be sleeved on the outside of the bit 4. The clamping block 304 is fixedly connected to the side of the adjusting nut 303 away from the threaded ring 302. The adjusting nut 303 is used to be threadedly connected to the threaded ring 302 so that the clamping block 304 presses and fixes the locking ring 301, which is inserted into the clamping block 304, against the bit 4. The structure of the second locking member 3 allows for easy adjustment and locking of the bit 4, ensuring the stability of the bit 4 under different working conditions.

[0036] In a preferred embodiment, the locking ring 301 is a conical ring with a first anti-slip groove 17 circumferentially provided and a second anti-slip groove 18 axially provided for the adjusting nut 303. By setting the locking ring 301 as a conical ring, the more the conical ring extends into the clamping block 304 during the tightening process between the adjusting nut 303 and the threaded ring 302, the more firmly the clamping block 304 locks the conical ring and the screwdriver bit 4, improving the reliability of the screwdriver. The first anti-slip groove 17 can further enhance the friction between the conical ring and the screwdriver bit 4, making the locking more secure. The second anti-slip groove 18 makes it easier to tighten the adjusting nut 303.

[0037] In a preferred embodiment, the maintenance screwdriver with a detachable protective structure also includes an anti-slip sleeve 12, which is fitted and fixed to the outer periphery of the handle 1. The anti-slip sleeve 12 can improve the stability of the maintenance personnel when holding the handle 1, prevent hand slippage, and improve work safety.

[0038] In a preferred embodiment, the repair screwdriver with a detachable protective structure further includes an LED bead 13 and a push-button switch 14. The LED bead 13 is fixedly connected to the end of the handle 1 facing the bit 4. The push-button switch 14 is electrically connected to the LED bead 13 to turn the LED bead 13 on or off. The push-button switch 14 is located at the end of the handle 1 away from the bit 4. The LED bead and push-button switch 14 can provide illumination in low-light environments, making operation convenient and improving work efficiency.
