Description

air tool

This creation is about a pneumatic tool.

Pneumatic tools use compressed air as the power source to make the driving mechanism rotate. Pneumatic tools include ratchet pneumatic wrench, T-shaped pneumatic wrench, gun-shaped pneumatic wrench, flat-shaped pneumatic wrench, etc. Taking the ratchet pneumatic wrench as an example, the known pneumatic tool includes a long rod end and a driving end, and the long rod end is provided with a driving switch.

In operation, one of the user's hands holds the end of the long rod to control the driving switch, while the other hand needs to hold the driving end to press the driving end to be stably combined with the workpiece to avoid slipping. However, it is necessary to hold the pneumatic tool with both hands, which causes inconvenience in use. For example, when dismantling and assembling workpieces, when it is necessary to replace the sleeve and take other workpieces, there is no hand to take them, and the disassembly and assembly must be stopped before they can be taken empty-handed, resulting in poor work efficiency.

Therefore, it is necessary to provide a novel and progressive pneumatic tool to solve the above-mentioned problems.

The main purpose of this creation is to provide a pneumatic tool that can simultaneously control the control handle with one hand while holding the driving head with one hand.

To achieve the above object, the invention provides a pneumatic tool, including: a main body, which includes a driving head and a grip, the driving head includes a driving shaft, the driving shaft is used to drive an object, the driving head and The grip is arranged in a first direction, the drive shaft extends in a second direction, the first direction is transverse to the second direction, a boundary line is defined between the drive head and the grip, and the boundary line is along One end of the drive head extends; and a control handle, which is swingably arranged on the main body, the handle includes a connecting portion and an operating portion, the connecting portion is pivotally arranged on the grip portion, and the operating portion is controlled by the handle. The joint extends at least through the boundary line.
