Handheld Ground Drill

Abstract

The invention discloses a hand-held drill. The hand-held drill belongs to the technical field of the garden machine. The drill comprises a drill bit and a working head, wherein the drill bit comprises a shell, a hand shank placed on the shell, a generator and a transmission gear both located inside the shell. The transmission gear comprises an output shaft which is connected with the working head. The generator drives the working head to rotate through the transmission gear which comprises a speed controller for adjusting the speed of the output shaft. The prepared product is an improvement in respect of the transmission gear. More Assembly for regulating speed is added. The speed of the output shaft is thus changed. The speed of the working head is adjusted because of the change. It is important to note that the speed of the working head can be changed according to the specific work, which, in turn, improves the commonality of the hand-held drill. Besides, the reform in the speed of the working head may prevent the working head or the generator or the transmission gear from damage, prolonging the life of each component.

Description

technical field [0001] The invention relates to the technical field of garden machinery, in particular to a hand-held ground drill. Background technique [0002] In order to plant trees or set up stake guardrails etc. in gardens, it is necessary to dig holes on the ground, and people generally use tools such as shovels to dig holes and plant trees. In order to improve work efficiency and reduce labor intensity, people have successively developed some motorized tools for gardening operations, which have greatly improved the mechanization of gardening operations. [0003] Currently, commercially available hand-held ground drills are generally driven by gasoline engines, which will generate exhaust gas and noise during use, which will pose a hazard to the health of the operator. There are specific restrictions on the transportation and use of gasoline, and gasoline is easy to cause fires. When gasoline is used as the power source of the engine, the environmental pollution caus...

AI Technical Summary

Problems solved by technology

[0003] At present, the commercially available hand-held ground drills are generally driven by gasoline engines, which will generate exhaust gas and noise during use, which is harmful to the health of operators

There are specific restrictions on the transportation and use of gasoline, and gasoline is easy to cause fires. When gasoline is used as the power source of the engine, the environmental pollution caused is relatively serious, and the maintenance cost of the engine is also high

In addition, the existing hand-held ground drills generally do not have the function of speed regulation, and the drill bit can only work at one speed, which cannot be adjusted according to the geology and the size of the pit, and cannot well meet the use requirements.
