Description

Technical Field

[0001] The utility model relates to the technical field of electric screwdrivers, in particular to a multifunctional electric screwdriver. Background Art

[0002] Electric screwdriver, also known as electric screwdriver, is an electric tool used to tighten and loosen screws. This electric tool is equipped with a mechanism to adjust and limit torque. It is mainly used in assembly lines and is one of the essential tools for most manufacturing companies.

[0003] In factories, electric screwdrivers are very common. When working, workers usually hold an electric screwdriver in one hand and multiple screws in the other hand. After tightening one screw, they immediately use both hands to match the groove on the screw nut with the screwdriver head of the electric screwdriver. However, in this process, the matching of the groove and the screwdriver head often requires the worker to either turn the screwdriver head or the screw to adjust the position of the two in the circumferential direction so that they can be matched. This requires the worker to divide his attention, which affects the speed of screw tightening. In addition, in practice, product parts are usually placed in a box. To open the box, you need to use a blade to cut the transparent sealing tape (transparent tape) of the box. It is more troublesome to take the blade and put it back, especially in assembly line work, it is easy to forget to put the blade back. Therefore, it is necessary to propose a new solution to the above problems. Utility Model Content

[0004] In view of this, the present invention aims at the defects of the prior art, and its main purpose is to provide a multifunctional electric screwdriver, which is used to solve the above problems.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] As a preferred solution, the handle and the electric head are connected so that the relative angle can be adjusted in multiple stages.

[0008] As a preferred solution, an adjusting member is fixedly connected to the rear end of the second shell, the adjusting member has a connecting shaft, the adjusting surface has a plurality of slots, and the plurality of slots are arranged in a circular trajectory around the rotating shaft, the first shell is rotatably connected to the connecting shaft, and a toggle button is provided at the front end of the first shell, the toggle button is connected to a card block and controls the card block to enter / exit the corresponding card slot.

[0009] As a preferred solution, the toggle button, forward and reverse control button, and slow control button are all arranged at the front end of the first housing.

[0010] As a preferred solution, the lower outer surface of the first shell has a finger gripping portion corresponding to the shape of a finger gripping portion, and the upper surface of the first shell is also provided with a plurality of anti-slip lines arranged at intervals along the length direction of the finger gripping portion.

[0011] As a preferred solution, the plastic cutting portion is arranged on the upper surface of the rear end of the second shell, and the plastic cutting portion is a triangular piece.

[0012] As a preferred solution, the upper surface of the rear end of the second housing is further provided with two guide ridges extending forward and backward, and the two guide ridges are arranged on both sides of the plastic cutting portion.

[0013] Compared with the prior art, the utility model has obvious advantages and beneficial effects. Specifically, it can be seen from the above technical solution that the main advantages are:

[0014] A slow-speed control button is designed, which can control the screwdriver head to rotate slowly when it is pressed. When the matching groove on the screw nut needs to be matched with the screwdriver head, the staff only needs to focus on the screwdriver head hitting the screw nut, and there is no need to adjust the angle position of the screwdriver head or the screw nut in the circumferential direction by hand. The screwdriver head can automatically rotate to the position corresponding to the groove of the screw nut, which can speed up the staff's screwing speed. It should be noted that although the forward and reverse control buttons can control the rotation of the screwdriver head, it is used for screwing and has a fast rotation speed, and cannot be used to adjust the circumferential position of the screwdriver head relative to the groove of the screw nut; in addition, the plastic cutting part is designed, so when the parts box needs to be opened at work, there is no need to find a blade to cut the transparent sealing tape of the box. Only the plastic cutting part of this product is needed, which is very convenient and it is not easy to forget to put the blade back in place after taking it.
