electric garden shears

Abstract

The invention relates to motor-driven tools, and in particular relates to a pair of novel motor-driven garden shears. The novel motor-driven garden shears comprise an upper machine shell, a lower machine shell, a cutter head part and a switch part, wherein the cutter head part is fixed on the upper machine shell; the switch part is fixed on the lower machine shell; an anti-rotating locking piece is arranged on the cutter head part; the anti-rotating locking piece is matched with a transmission gear which is used for connecting two cutter blades; the upper machine shell and the lower machine shell are internally provided with a motor controller and transmission mechanism; the motor controller and transmission mechanism comprises a circuit controller, a direct-current brushless motor, a planet wheel speed reducing box and a ball screw rod mechanism which are connected together; the circuit controller is positioned at the rear side of the direct-current brushless motor; the ball screw rod mechanism is arranged at the front side of the planet wheel speed reducing box; the front end of the ball screw rod mechanism is fixedly provided with two connecting plates; and the connecting plates are fastened on two sides of the connecting plates by clamping rings. The novel motor-driven garden shears adopt a backpack type lithium battery as a power supply, the power supply can be connected or disconnected by a battery switch, the equipment motor is started, and a trigger can be pulled by holding equipment, so that work is performed.

Description

technical field [0001] The invention relates to an electric tool, in particular to an electric garden shear. Background technique [0002] Cutting fruit tree branches and vines are now commonly used manual garden shears, which are not only laborious and labor-intensive to use, but also have low work efficiency, and are not suitable for pruning large-scale fruit trees and vines. At present, there are also electric garden shears on the market, which are powered by motors. After gear reduction, the blades are driven to cut, so as to achieve the purpose of pruning and trimming, and also improve work efficiency. However, the shortcomings of existing electric garden shears are as follows Two points: 1. The locking device of the cutter head part is easy to loosen during use; 2. The transmission structure uses gear transmission, the transmission is not stable, and the service life is low. Contents of the invention [0003] In order to solve the above problems, the present inventi...
