Description

Technical Field

[0001] The utility model relates to the field of electric tools, in particular to a handheld electric tool. Background Art

[0002] In the prior art, the arrangement of the motor and the output shaft of the electric tool is mostly such that the motor axis is parallel to the output shaft, and the power can be directly output. For the arrangement in which the motor axis is parallel to the output shaft, the axial dimension of the motor is larger than the diameter of the motor, and the axial dimension of the motor occupies most of the axial direction of the output shaft, making it inconvenient to operate the whole machine in a small space. The electric tool as a whole will appear relatively wide, the entire structure is not small enough, and the space occupied is too large. In addition, the center of mass of the whole machine is biased to one side of the motor housing. When holding it, the torsional torque needs to be overcome, which makes it uncomfortable to operate for a long time. As a result, the operability and accessibility are relatively poor, which greatly affects the work efficiency and brings great troubles to the user. Utility Model Content
