[0002] Car maintenance is a general term for car maintenance and repair. When repairing a car, a screwdriver is generally used. Traditional screwdrivers are all one-piece, with the handle and the shank fixedly connected. The metal shank is relatively long, and the front end is usually a straight or cross-shaped blade.
[0003] Since there are many parts inside the car and they are compactly arranged, such as in the front of the car and chassis, some screws are visible from the front and can be operated by simply inserting a screwdriver. However, there are also many screws facing sideways and in narrow spaces, and traditional screwdrivers cannot turn and reach in to operate them.
[0004] There are many improved screwdrivers for automobile repair in the prior art, such as CN207509108U, a screwdriver for automobile repair, CN206643831U, a screwdriver for automobile repair that is easy to replace the cutter head, etc. However, the cutter head and the cutter bar are still the traditional straight line design, which is not suitable for side screws in narrow spaces.

The hexagonal column can be magnetically plugged in and out with the hexagonal slot A, and the hexagonal slot B can be magnetically plugged in and out with the screwdriver head. When the tool head seat is inserted into the auxiliary sleeve, the bevel gear plate B can be vertically engaged with the bevel gear plate A and the port of the hexagonal slot B is limited.
[0010] As an improvement, the main sleeve is fixedly connected to the auxiliary sleeve and has an outer right-angle opening.
[0011] As an improvement, the secondary sleeve is 1-5 cm long.
[0012] As an improvement, the central axes of the tool rod, the hexagonal slot A, and the bevel gear disc A coincide.
[0013] As an improvement, the handle is rotatably connected to the rear end of the main sleeve via a thread.
[0014] As an improvement, the handle is magnetically connected to the rear end of the main sleeve, and the main sleeve can slide away from the handle to disengage from the magnetism.
[0015] As an improvement, a battery module and a motor are provided in the handle, the output shaft of the motor is fixedly connected to the rear end of the knife rod, and a button is provided at the rear end of the handle, and the button, battery module and motor are electrically connected.
[0016] The advantages of the utility model compared with the prior art are: open space usage, such as Figure 1 : Insert the screwdriver head into the hexagonal slot B of the bit seat and fix it magnetically, then insert the hexagonal column into the hexagonal slot A and fix it magnetically, and then hold the handle to turn and disassemble the screw.
[0017] Narrow space usage status, such as Figure 2 , Figure 7 : First pull out the cutter head seat, then rotate the main sleeve to extend it to the front end beyond the bevel gear plate A. Figure 4 State, then insert the cutter head holder and the screwdriver head into the auxiliary sleeve to the bottom, the cutter head holder is limited but can rotate, the hexagonal column faces the helical gear plate A, and the screwdriver head is exposed from the sleeve, refer to Figure 6 , Figure 3 Finally, rotate the main sleeve to return it until the bevel gear plate A and the bevel gear plate B are in contact and meshing. Then you can hold the handle and insert the screwdriver head into the narrow space, insert the screwdriver head 5 into the side screw and rotate it for disassembly and assembly.
[0018] The handle and the main sleeve can also be directly connected by magnetic attraction. To extend the main sleeve to the front end beyond the bevel gear plate A, the main sleeve can be directly pulled out.
[0019] A battery module and a motor are added to the handle, such as Figure 5 The motor can drive the tool rod to rotate. In the above two usage states, pressing the button can electrically control the rotation of the screwdriver head to improve the disassembly and assembly efficiency.
