[0022] Please see Figs. 1-3 An electric screwdriver with an adjustable handle angle includes a screwdriver body 1, a connecting rod 2 installed at one end of the screwdriver body 1, a connecting sleeve 3 provided on one side of the outer wall of the connecting rod 2, a first mounting seat 4 installed on the upper and lower sides of one end of the connecting sleeve 3, a second mounting seat 5 provided between the two first mounting seats 4, an adjustment mechanism 6 provided on the inner side of the second mounting seat 5, and an adjustable length handheld part 7 installed at one end of the second mounting seat 5.

[0023] like Figs. 1-3 As shown, one end of the connecting rod 2 is provided with a first threaded groove 8, and one end of the inner side of the connecting sleeve 3 is provided with a first threaded rod 9 that mates with the first threaded groove 8. The first threaded groove 8 and the first threaded rod 9 allow the connecting rod 2 to move inside the connecting sleeve 3, thereby adjusting the distance between the screwdriver body 1 and the connecting sleeve 3 to adapt to different working environments.

[0024] like Figs. 1-3 As shown, the adjustment mechanism 6 includes a first circular plate 601 that is installed through the top of the second mounting base 5. The upper and lower ends of the first circular plate 601 are provided with second circular plates 602 installed inside the first mounting base 4. The top of the upper second circular plate 602 is provided with a first mounting groove 603. The first mounting groove 603 is threadedly connected to a mounting rod 604. The top of the mounting rod 604 is connected to an adjustment handle 605. When it is necessary to adjust the angle between the handle 7 and the connecting sleeve 3, it is only necessary to control the adjustment handle 605 so that the bottom of the mounting rod 604 does not extend below the first mounting base 4. At this time, the first mounting base 4 and the second mounting base 5 are rotatably connected and the angle can be freely adjusted.

[0025] like Figs. 1-3 As shown, a second mounting groove 10 is provided through the top center of the first circular plate 601. The second mounting groove 10 and the mounting rod 604 are threadedly connected. When it is necessary to fix the angle between the handheld part 7 and the connecting sleeve 3, it is only necessary to control the adjusting handle 605 to make the mounting rod 604 rotate and extend into the second mounting groove 10 so that the first circular plate 601 and the second circular plate 602 are integrally fixed. At this time, the first mounting base 4 and the second mounting base 5 are fixedly connected.

[0026] like Figs. 1-3 As shown, the outer sides of the upper and lower ends of the first circular plate 601 are provided with annular grooves 11. Inside the annular grooves 11, there are annular blocks 12 fixed to the end of the second circular plate 602 facing the first circular plate 601. The annular grooves 11 and the annular blocks 12 make the first circular plate 601 and the second circular plate 602 rotatably connected, and can move freely without the restraint of the mounting rod 604.

[0027] like Figs. 1-3 As shown, the handheld part 7 includes a fixed rod 701 fixed to one end of the second mounting base 5. One end of the fixed rod 701 is provided with a second threaded groove 702. The second threaded groove 702 is internally threaded with a second threaded rod 703. One end of the second threaded rod 703 is connected to a rotating sleeve 704 rotatably disposed on the outer wall of the fixed rod 701. The second threaded groove 702 and the second threaded rod 703 allow the rotating sleeve 704 to move left and right on the outer wall of the fixed rod 701, thereby adjusting the length of the handheld part 7 to adapt to work under various conditions.

[0028] Working principle: During use, the first threaded groove 8 and the first threaded rod 9 allow the connecting rod 2 to move inside the connecting sleeve 3. The second threaded groove 702 and the second threaded rod 703 allow the rotating sleeve 704 to move left and right on the outer wall of the fixed rod 701, thereby adjusting the length of the handle 7. This allows for free control of the extension length of the screwdriver body 1 and the length of the handle 7, adapting to different working environments. When it is necessary to adjust the angle between the handle 7 and the connecting sleeve 3, simply control the adjusting handle 605 so that the bottom of the mounting rod 604 does not extend below the first mounting base 4. At this time, the first mounting base 4 and the second mounting base 5 are rotatably connected and the angle can be freely adjusted. When it is necessary to fix the angle between the hand handle 7 and the connecting sleeve 3, it is only necessary to control the adjusting handle 605 to make the mounting rod 604 rotate and extend into the second mounting groove 10 so that the first circular plate 601 and the second circular plate 602 are integrally fixed. At this time, the first mounting base 4 and the second mounting base 5 are fixedly connected. The circular groove 11 and the circular block 12 make the first circular plate 601 and the second circular plate 602 rotatably connected and can move freely without the restraint of the mounting rod 604.

[0029] 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.
