[0023] Please see Figure 1-6 This utility model provides a technical solution:

[0024] A portable lithium battery-powered electric screwdriver includes an electric screwdriver body 1, a protective component 2, and an anti-dislodgement component 3. The electric screwdriver body 1 includes a screwdriver body 11, with a wear-resistant and anti-slip sleeve 15 fixedly connected to the outer side of the screwdriver body 11. A first threaded sleeve 16 is fixedly connected to the upper outer part of the screwdriver body 11, and a second threaded sleeve 17 is fixedly connected to the lower outer part of the screwdriver body 11. The protective component 2 is provided on the upper side of the electric screwdriver body 1. The protective component 2 includes a protective sleeve 21 threadedly connected to the first threaded sleeve 16, and a limiting seat 22 is fixedly connected to the inner side of the protective sleeve 21. The lower side of the limiting seat 22 is provided with a receiving groove 23, and the upper side of the limiting seat 22 is provided with multiple limiting grooves 24. Each limiting groove 24 is provided with a spare cutting head 25. The outer side of the limiting seat 22 is threaded with a protective cover 26. The outer side of the electric screwdriver body 1 and the protective component 2 is provided with an anti-detachment component 3. The anti-detachment component 3 includes a fixing ring 31 that is fixedly connected to the outer side of the wear-resistant and anti-slip sleeve 15. Above the fixing ring 31 is a rotating ring 32 that is rotatably connected to the outer side of the protective sleeve 21. The front side of the rotating ring 32 is fixedly connected with a portable 33, and the lower end of the portable 33 is fixedly connected to the front side of the fixing ring 31.

[0025] A rechargeable lithium battery 12 is installed on the lower rear side of the screwdriver body 11, and a push switch 13 is installed on the upper rear side of the screwdriver body 11. A screwdriver head 14 is installed on the upper side of the screwdriver body 11, and the screwdriver body 11 can rotate the screwdriver head 14. The rechargeable lithium battery 12 passes through the rear opening of the wear-resistant anti-slip sleeve 15. The first threaded sleeve 16 and the second threaded sleeve 17 are at the same height. The internal thread of the protective sleeve 21 matches the second threaded sleeve 17. The protective sleeve 21 can be screwed onto the outside of either the first threaded sleeve 16 or the second threaded sleeve 17. The outer diameter of the protective sleeve 21 and the protective cover 26... The outer diameter of the protective sleeve 21 is equal to the outer diameter of the wear-resistant and anti-slip sleeve 15. The lower side of the protective sleeve 21 is fitted with the upper end of the wear-resistant and anti-slip sleeve 15, and the lower end of the protective cover 26 is fitted with the upper end of the protective sleeve 21. The limiting seat 22 and the spare blade 25 can be stored through the protective sleeve 21 and the protective cover 26. The upper end of the screwdriver body 11 and the screwdriver blade 14 are both located in the receiving groove 23. The diameter of the limiting groove 24 is equal to the diameter of the spare blade 25. The spare blade 25 is tightly fitted with the limiting seat 22. The side of the limiting groove 24 of the limiting seat 22 is relatively rough. The friction of the limiting seat 22 can fix the screwdriver blade 14 in the limiting groove 24.

[0026] Workflow: Before use, fully charge the rechargeable lithium battery 12 and check if the device is intact. If intact, the device can be used. Before using the device, the operator can carry the device with them by hand. When using the device, the operator first unscrews the protective cover 21 from the outside of the first threaded sleeve 16, then screws the protective cover 21 onto the outside of the second threaded sleeve 17. Then, unscrew the protective cover 26 from the limiting seat 22, take out the required spare screwdriver bit 25 from the limiting groove 24 of the limiting seat 22, remove the screwdriver bit 14 from the screwdriver body 11, and install the specific spare screwdriver bit 25 into the screwdriver body 11. On the screwdriver body 11, the screwdriver bit 14 is placed into the limiting groove 24. The side of the limiting groove 24 of the limiting seat 22 is relatively rough. The friction of the limiting seat 22 can fix the screwdriver bit 14 in the limiting groove 24. Then, the operator screws the protective cover 26 back onto the outside of the limiting seat 22. The device can then be used. The operator holds the wear-resistant and anti-slip sleeve 15 and presses the push switch 13. The rechargeable lithium battery 12 can power the screwdriver body 11. Pressing the push switch 13 can start the screwdriver body 11, causing the screwdriver body 11 to drive the screwdriver bit 14 to rotate. The device is then ready for normal use. After use, the operator can unscrew the nut protective sleeve 21 from the outside of the second threaded sleeve 17 and then screw the protective sleeve 21 back onto the outside of the first threaded sleeve 16. The limiting seat 22 inside the protective sleeve 21 can protect the screwdriver head 14. The side of the receiving groove 23 of the limiting seat 22 is relatively smooth, and the contact area between the limiting seat 22 and the upper end of the screwdriver body 11 is small, so the limiting seat 22 will not damage the screwdriver body 11. The portable 33, together with the fixing ring 31 and the rotating ring 32, can limit the relative distance between the protective sleeve 21 and the wear-resistant and anti-slip sleeve 15, preventing the protective sleeve 21 from being lost. When the operator twists the protective sleeve 21, the rotating ring 32 will rotate relative to the protective sleeve 21, ensuring that the portable 33 will not get tangled on the outside of the wear-resistant and anti-slip sleeve 15. The device can protect the screwdriver head 14 through the limiting seat 22 inside the protective sleeve 21, and at the same time store multiple spare heads 25. The portable 33 can prevent the protective sleeve 21 from being lost, and at the same time make the device easier to carry or hang. The device is more convenient to carry or store, and can protect the screwdriver head 14 from being bumped and avoid the screwdriver head 14 from causing injury to the carrier.
