Description

Title of Invention: A Tool for Screwing Cars

Technical field

[0001] The present invention relates to a screw tool, and more particularly to a tool for screwing a car.

Background technique

[0002] The tools for turning screws in automobiles are mainly wrenches, or hydraulic and electric wrenches. These wrenches are rigid. In actual use, due to structural limitations, some places are very difficult to place in places where screws need to be screwed. Or put it in, the amount of rotation is small, which makes car maintenance very inconvenient.

technical problem

[0003] The head space of some screws is very small, and the wrench cannot be put in. The soft shaft of the tool mentioned above in the application of the applicant is straight-in type and needs to occupy a part of the space.

Problem solution

Technical solution

[0004] The present invention is directed to the above-mentioned technical problem, and proposes a tool for screwing a car, by which a tool can be placed in a desired position with a small gap, which is very convenient.

[0005] The technical solution of the present invention is as follows:

[0006] A tool for screwing a car, the tool comprising a handle, a housing, a motor, an armrest, a switch, a flexible shaft connector, a flexible shaft, and a screw hole head;

[0007] the handle is connected to the housing, the motor is installed in the housing, and the armrest is disposed on two sides of the housing;

[0008] the guard is disposed on the armrest;

[0009] the motor output shaft is connected to the flexible shaft connector, the flexible shaft connector is connected to the flexible shaft, and the other end of the flexible shaft is connected to the side of the screw hole head;

[0010] The bevel gear pair is disposed in the threaded head, and the rotation of the side of the threaded head transmitted from the flexible shaft can be converted into a positive rotation.

[0011] Further, a reducer is further disposed in the housing between the motor and the flexible shaft output head.

[0012] Further, the armrest is further provided with a gear position controller, and the gear position controller is configured with at least two gears. Bit.

[0013] Further, the screw head can be replaced.

Advantageous effects of the invention

Beneficial effect

[0014] According to the above technical solution, first, since the flexible shaft can be bent and deformed to some extent, the user only needs to put the screw hole head into the place where the screw or the bolt is located, and the motor can be screwed or screwed. The operation of the upper screw, the second is that when the head space of the screw is very small, the movement can be converted into the front rotation by connecting the flexible shaft to the side of the screw head and the movement of the bevel gear pair, so that it can be connected very much. Large space.

Embodiments of the invention

Example embodiments will now be described more fully with reference to the accompanying drawings. However, the example embodiments can be embodied in a variety of forms, and should not be construed as being limited to the examples set forth herein; rather, these embodiments are provided to make the invention more comprehensive and complete, and the concept of the example embodiments is fully conveyed. To those skilled in the art. The drawings are only schematic representations of the invention and are not necessarily to scale. The same reference numerals in the drawings denote the same or similar parts, and the repeated description thereof will be omitted.

Furthermore, the described features, structures, or characteristics may be combined in any suitable manner in one or more embodiments. In the following description, numerous specific details are set forth However, those skilled in the art will appreciate that the technical solutions of the present invention may be practiced without omitting one or more of the specific details, or other methods, components, devices, steps, etc. may be employed. In other instances, various aspects of the invention may be <RTIgt; </ RTI> <RTIgt; </ RTI> <RTIgt; </ RTI> <RTIgt; </ RTI> <RTIgt;

[0019] As shown in FIG. 1, a tool for screwing a car, the tool includes a machine head and an execution end, and the head portion is packaged The handle 1 is included, and the handle 1 can be easily moved without the tool being used.

[0020] Motor 2, motor 2 includes an outgoing power cord that requires an external power source. The output of motor 2 has a reducer

, you can get the power of slow high torque.

[0021] The output end of the reducer is connected to the flexible shaft connector 5, the flexible shaft connector 5 is connected to the flexible shaft 7, and the other end of the flexible shaft 7 is connected to the screw hole head 8, and FIG. 2 is a view from the lower side of FIG. Schematic diagram of the screw head 8.

[0022] The flexible shaft is connected to the side of the screw head 8 , and the bevel gear pair is disposed in the screw hole head 8 , and the flexible shaft is connected to one of the gear shafts of the bevel gear pair, and the rotary shaft of the flexible shaft can be rotated by the action of the bevel gear pair Convert to a vertical direction.

[0023] In addition, the motor has a shut-off 4 and a gear position controller 6, and the gear position controller 6 can set two or more gear positions to accommodate different torques.

[0024] The screw head 8 of the present invention can be replaced to accommodate different sized screws or bolts.

[0025] According to the above technical solution, one is that since the flexible shaft can be bent and deformed to some extent, the user only needs to put the screw hole head into the place where the screw or the bolt is located, and then the motor can be screwed. Or the operation of the upper screw, the second is that when the space on the top of the screw is very small, the movement can be converted into the front rotation by connecting the flexible shaft to the side of the screw head and the movement of the bevel gear pair, so that the screw can be connected A lot of space.

[0026] Finally, it should be noted that the above embodiments are only for explaining the technical solutions of the present invention, and are not intended to be limiting; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should It is to be understood that the technical solutions described in the foregoing embodiments may be modified, or some or all of the technical features may be equivalently replaced; and the modifications or substitutions do not deviate from the essential embodiments of the present invention. The scope of the technical solution.
