Description

Technical Field

[0001] The utility model relates to the technical field of air shovels, in particular to a handheld air shovel. Background Art

[0002] An air shovel is a tool that uses compressed air as a power source, and is mainly used for digging, excavation, crushing and other work. Its working principle is to drive the pneumatic motor through compressed air, and then transfer energy to the tool through the movement of the cylinder and piston, so as to achieve the working purpose. Specifically, when the air shovel is needed, high-pressure gas is sent into the cylinder, and the gas pressure at the cylinder air inlet drives the cylinder piston to move up or down. During this process, the spring mechanism ensures that the piston always remains in the lower position for the next operation. When the cylinder piston moves upward, it drives the bucket to move upward; conversely, when it moves downward, the corresponding work is performed.

[0003] The air shovel is widely used, mainly including casting sand removal, deburring of large, medium and small castings, cutting weld slopes, and correcting the openings of stone, concrete and brick walls. In addition, the air shovel is also used for cutting various metal components in boiler shipbuilding, metallurgical industry and other industries, especially for cutting irregular or narrow and inconvenient surfaces.

[0004] As shown in the application document with the prior art publication number CN202781070U, it includes a gun body, a handle is provided at the bottom of the gun body, a tension spring is provided at the front end of the gun body, and an exhaust hood is provided on the gun body. The exhaust hood is connected to the gun body by threads. The technical solution is provided with an exhaust hood that can rotate at a certain degree, and the exhaust hood can be rotated at will during use to prevent gas from directly spraying the user.

[0005] However, during actual operation, the above technical solution is prone to falling out of hands due to shaking, thereby damaging the air shovel. At the same time, the fallen air shovel is also likely to cause harm to the staff. As a result, this technical solution has certain limitations and cannot enable the staff to operate it more conveniently and effectively. Utility Model Content
