[0038] The power assembly 100 also includes a power slot 102a disposed in the carrier frame 301, and the power rod 102 is connected to the power slot 102a. Through the power rod 102 disposed inside the carrier frame 301, the power gun 101 and the power rod 102 drive the internal components of the carrier frame 301 to move.

[0039] Usage process: When it is necessary to work on multiple bolts, first align the multiple external components 400 with the screws to be worked on, drive the driving key on the power gun 101, drive the power rod 102 to rotate through the power gun 101, drive the linkage component 300 to rotate through the power rod 102, and drive the front external component 400 through the linkage component 300 to work on the multiple bolts, so as to quickly disassemble or install them, thereby improving work efficiency.

[0040] Example 2

[0041] Reference Figures 1 to 4, which is the second embodiment of the utility model. Different from the previous embodiment, it also includes: the linkage assembly 300 also includes a driving gear 302 arranged inside the carrier frame 301, a transmission gear 303 is provided above the driving gear 302, a fixed gear 304 is provided above the transmission gear 303, a first connecting gear 304a and a first linkage gear 304b are provided on both sides of the fixed gear 304, and a second connecting gear 304a-1 is provided on one side of the first connecting gear 304a, and transmission is performed through multiple gears arranged inside the linkage assembly 300, thereby driving multiple screwdriver bits 402 to work on the bolts.

[0042] A second linkage gear 304b-1 is provided at one end of the first linkage gear 304b, and the power rod 102 is connected to the driving gear 302. The power rod 102 is connected to the driving gear 302 through the power rod 102, so that when the power rod 101 drives the power rod 102 to rotate, the power rod 102 drives the driving gear 302 to rotate, and the driving gear 302 drives the subsequent components to move.

[0043] The external component 400 further includes a connection slot 401 disposed at one end of the carrier frame 301 , in which a screwdriver bit 402 is disposed. The multiple screwdriver bits 402 disposed in the carrier frame 301 can enable the multiple screwdriver bits 402 to work.

[0045] The screwdriver bits 402 are arranged in an array in the carrying frame 301 .

[0046] Usage process: First, multiple screwdriver bits 402 are calibrated with multiple bolts. After the screwdriver bits 402 are calibrated with the bolts, the power gun 101 drives the power rod 102 to rotate, and the power rod 102 drives the driving gear 302 to rotate, and then the driving gear 302 is meshed with the transmission gear 303, so that the transmission gear 303 rotates. After the transmission gear 303 rotates, the transmission gear 303 meshes with the fixed gear 304, so that the fixed gear 304 rotates. After the fixed gear 304 rotates, the fixed gear 304 and the first connecting gears 304a on both sides are connected. The first connecting gear 304a and the first connecting gear 304b are meshed with each other, and the first connecting gear 304a and the first connecting gear 304b are respectively meshed with the outer second connecting gear 304a-1 and the second connecting gear 304b-1, so that the second connecting gear 304a-1 and the second connecting gear 304b-1 rotate, and the screwdriver bit 402 is driven to rotate at the same time through the fixed gear 304, the second connecting gear 304a-1 and the second connecting gear 304b-1, thereby achieving work on multiple bolts, thereby reducing time loss and improving work efficiency.

[0047] Example 3

[0048] Reference Figures 1 to 6 , which is the third embodiment of the utility model, and further provides an electric screwdriver. It includes an adjustment assembly 500, including an adjustment frame 501 disposed inside the carrying frame 301, a threaded rod 502 disposed inside the adjustment frame 501, and a fixing frame 504 disposed inside the carrying frame 301; and

[0049] The connecting rod assembly 200 includes a first connecting rod 201 and a first operating rod 202 which are disposed at one end of the fixing frame 504 .

[0050] The adjustment component 500 also includes a rotating shaft 503 arranged at one end of the threaded rod 502, and a rotating plate 503a is provided on the outside of the rotating shaft 503, a sliding block 503a-1 is provided at one end of the rotating plate 503a, and a fixed block 503a-2 is provided at one end of the rotating plate 503a. A second elastic member 504a is provided inside the fixed frame 504, and the second elastic member 504a is connected to the sliding block 503a-1. The rotating shaft 503 is driven by the threaded rod 502. When the rotating shaft 503 moves downward, the rotating shaft 503 drives the fixed frame 504 to gradually move toward both ends, and then drives the subsequent components to move through the rotating shaft 503.

[0051] The connecting rod assembly 200 also includes a second connecting rod 201a arranged at one end of the first connecting rod 201 and a second operating rod 202a arranged at one end of the first operating rod 202. The second connecting rod 201a is connected to the second operating rod 202a. An adjustment groove 203 is provided inside the supporting frame 301. The fixed frame 504 is respectively connected to the second linkage gear 304b-1 and the second connecting gear 304a-1. The adjusting assembly 500 drives the connecting rod assembly 200 to move, so that the connecting rod assembly 200 is in a parallel state. The connecting rod assembly 200 drives the linkage assembly 300 to move, thereby realizing the adjustment of the spacing of the linkage assembly 300.

[0052] Usage process: when the spacing of the bolts to be worked on is too large, the threaded rod 502 is rotated, and the rotating shaft 503 is driven downward by the threaded rod 502. During the downward movement of the rotating shaft 503, the rotating shaft 503 drives the center position of the rotating plates 503a on both sides to deflect, so that the angle of the rotating plates 503a on both sides is reduced, and the two ends of the rotating plates 503a drive the fixed frame 504 to gradually move toward the two ends. After the fixed frames 504 on both sides move to both sides, the fixed frame 504 drives the first connecting gear 304a and the first linkage gear 304b to move, so that the first connecting gear 304a and the first linkage gear 304b are in a parallel position. When the second connecting gear 304a-1 and the second linkage gear 304b-1 move to both sides, the second connecting gear 304a-1 and the second linkage gear 304b-1 drive the front screwdriver bit 402 to move to both sides until it is aligned with the bolts, thereby working on bolts with different spacings, increasing its applicability.
