Description

Technical Field

[0001] This utility model relates to the field of screwdriver technology, and in particular to a screwdriver with a grinding function. Background Technology

[0002] A screwdriver is a common tool used to tighten screws into place. It typically has a thin wedge-shaped head that inserts into the slot or recess of the screw head. There are two main types: flathead (minus sign) and Phillips head (positive sign). Hex screwdrivers are also common, including both internal hex and external hex types.

[0003] However, in the existing technology, screw holes or screw heads will rust, be damaged or worn after long-term use. After the screw is installed, the screw head or the surrounding surface needs to be polished. Existing screwdrivers do not have the function of polishing, and other tools are required, which is cumbersome, time-consuming and labor-intensive. In order to solve the above problems, a screwdriver with polishing function is proposed. Utility Model Content

[0004] The purpose of this invention is to solve the problem that existing screwdrivers do not have a grinding function, require the use of other tools, and are cumbersome, time-consuming, and labor-intensive to operate. Therefore, this invention proposes a screwdriver with a grinding function.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a screwdriver with a grinding function, comprising a handle, a servo motor, and a connecting rod. The output end of the servo motor is drivenly connected to a rotating shell. Multiple sets of limiting grooves are formed on the inner wall of the rotating shell. A screwdriver head is fixedly installed at one end of the connecting rod, and a grinding head is fixedly installed at the other end. A fixing sleeve is fixedly installed on the outer wall of the connecting rod, and a connecting sleeve is rotatably connected to the outer wall of the fixing sleeve. When it is necessary to replace the screwdriver head or grinding head, the correct end of the connecting rod is placed outside the handle, and the other end is inserted into the rotating shell, so that the outer wall of the fixing sleeve contacts the inner wall of the limiting groove, causing the inner wall of the rotating shell and the outer wall of the fixing sleeve to engage. As the connecting rod moves downwards, the connecting sleeve gradually enters the handle. At one end of the handle, rotating the connecting sleeve causes the connecting sleeve and the rotating shell to connect threadedly, thereby connecting the fixed sleeve and the rotating shell. Then, the servo motor is started to drive the rotating shell and the connecting rod to rotate, realizing the rotation of the cutting head and the grinding head. By setting the connecting rod, the fixed sleeve, and the connecting sleeve, the screwdriver can easily switch between the cutting head and the grinding head as needed, realizing multiple functions. It can tighten or loosen screws, and can also perform surface grinding and repair. Screw holes or screw heads may rust, be damaged, or wear after long-term use. The grinding head can be used to grind the screws. After installing the screws, the screw head or the surrounding surface can be ground, which improves the versatility of the tool. It eliminates the need for frequent tool changes. Simply changing the cutting head or the grinding head can quickly and conveniently complete different work tasks, improving work efficiency.

[0006] Preferably, the servo motor is fixedly installed inside the hand handle, and the outer wall of the rotating shell is rotatably connected to the inner wall of the hand handle. The servo motor is a bidirectional motor that can drive the connecting rod to rotate in different directions. The servo motor emits relatively little heat, which can be dissipated through the gap between the rotating shell and the hand handle, or through heat transfer from the hand handle. A push-button switch is provided on the side of the servo motor connected to the hand handle, and the operation and stop of the servo motor can be controlled by pressing the switch on the hand handle side.

[0007] Preferably, one end of the connecting rod is located inside the rotating shell, and the outer wall of the fixed sleeve is engaged with the inner wall of the rotating shell. By setting the fixed sleeve and the rotating shell, and the design of the outer wall protrusion of the fixed sleeve engaging with the inner wall of the rotating shell, the fixed sleeve is effectively prevented from sliding or rotating inside the rotating shell, ensuring that the position between the fixed sleeve and the rotating shell is fixed, avoiding misalignment or loss of control during use, improving the stability of the screwdriver, reducing shaking and loosening during use, reducing vibration and impact of the screwdriver during operation, and reducing the wear of parts.

[0008] Preferably, one end of the connecting sleeve is disposed inside the handle, and the inner wall of the connecting sleeve is threadedly connected to the outer wall of the rotating shell. By providing the connecting sleeve, as the connecting rod moves downward, the connecting sleeve gradually enters one end of the handle. At this time, rotating the connecting sleeve causes the connecting sleeve and the rotating shell to be threadedly connected, thereby realizing the connection between the fixed sleeve and the rotating shell.

[0009] Preferably, the outer wall of the handle has multiple sets of grooves. By setting multiple sets of grooves, the friction of the outer wall of the handle can be increased, so that the user can grip the handle more firmly during use and prevent the screwdriver from falling.

[0010] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0011] 1. In this utility model, by setting a connecting rod, a fixing sleeve, and a connecting sleeve, the screwdriver can easily switch between the cutting head and the grinding head as needed, realizing multiple functions.
