Electric tool

Abstract

The invention relates to an electric tool. The electric tool comprises a machine shell assembly, a blade assembly, a power supply assembly, a motor located in the machine shell assembly and a lead screw assembly in transmission connection with the motor and the blade assembly. The machine shell assembly comprises a trigger assembly, and the electric tool further comprises a dustproof assembly anda safety switch; a notch is formed in the attaching position of the machine shell assembly and the blade assembly, and the dustproof assembly is located at the notch so as to seal the notch in the using process of the blade assembly; and the safety switch is connected with the trigger assembly, and the safety switch is provided with a first position for locking the trigger assembly and a second position for unlocking the trigger assembly. According to the electric tool, the smooth shearing action of the blade assembly can be guaranteed, and meanwhile, good dust prevention, pollution preventionand use safety are achieved.

Description

technical field [0001] The invention relates to the technical field of garden instruments, in particular to an electric tool with easy operation. Background technique [0002] In garden fruit tree pruning, the powerful power and comfort of lithium electric scissors have gradually replaced the usual large manual scissors. While greatly improving work efficiency and quality, the user's work intensity is also reduced exponentially. In some working environments, there are many sand and dust particles. In this case, the failure rate of lithium electric scissors becomes very high. After dust particles enter the inside of lithium electric scissors with extremely precise transmission structure, the performance life of the scissors will be greatly reduced. , and may lead to direct failure, so in lithium electric scissors, the dust-proof structure during work is particularly critical. [0003] Lithium electric scissors, the fuselage is generally fully wrapped, two blades are exposed ...

AI Technical Summary

Problems solved by technology

[0003] Lithium electric scissors, the fuselage is generally fully wrapped, two blades are exposed from the fuselage, and the cutting is realized under the drive of lithium battery. The cutter head is mainly composed of fixed knife, moving knife and casing. During the cutting process, the finely divided wood slag and the sludge on the bark will be brought into the casing by the blade, and the dust in the environment will also enter the inside of the scissors through the pores of the casing and the blade, whether it is a screw or a pendulum. The tooth structure requires a good lubricating environment during transmission. If dirt enters the transmission system or contaminates the grease, the screw slide rail will be stuck due to the dirt, requiring the user or the maintenance point to dismantle the machine frequently to remove the dirt and clean it. There are many cases of failure of components and complete machines, and the dust-proof effect of the existing scissors dust-proof structure is not satisfactory

[0004] At the same time, the design of electric scissors is often accompanied by a trigger. When the trigger is pulled, the blade closes, and when the trigger is released, the blade opens, which makes cutting fruit tree branches very simple. The regulations require that tools such as electric scissors need to be operated with double actions, that is, a safety switch structure needs to be added to the current scissors. Considering the working process of lithium electric scissors, the blades need to be opened and closed frequently to achieve a large amount of cutting work. If you need to use double actions to open every time you cut, it will greatly reduce the user experience
