Problems solved by technology

[0003] However, there are deficiencies in this pruning machine
The movable blade of this kind of pruning machine is driven by the elastic force of the spring. When cutting branches, manual operation is required to push the movable blade to overcome the elastic force of the spring to open the knife edge, and then use the spring restoring force to drive the movable blade to reset to cut the branches. Troublesome and laborious, labor-intensive, people are prone to fatigue, which greatly affects work efficiency
It can only cut relatively small branches. When encountering relatively thick branches, the spring force is not enough to generate high shearing force, resulting in failure to cut and greatly reducing work reliability.

Embodiment Construction

[0052] Such as figure 1 Shown is a trimmer 1 according to one embodiment of the invention. The shell 2 of the trimmer 1 extends along a longitudinal direction. The housing 2 has a front end 21 and a rear end 22 in the lengthwise direction. At the rear end 22 of the housing 2 is provided a grip portion 12 for gripping. The grip part 12 can be set to rotate at a certain angle relative to the housing 2 . Such as figure 2 As shown, a rotating shaft 15 is provided between the housing 2 and the holding portion 12 , and the holding portion 12 can rotate around the rotating shaft 15 . A more preferred rotation angle of the handle portion 12 is 0 to 90 degrees. This makes it easier to cut branches in corners. The rear end 22 of the housing 2 is also provided with a switch 13 for starting the pruning machine 1 . Certainly, the position of the switch 13 can be set at any suitable position of the housing 2 , as long as the position of the switch 13 is convenient for the operator t...

Abstract

The invention relates to a tree trimmer, comprising a shell extending in the longitudinal direction, a motor located in the shell and providing rotary output, a transmission mechanism connected with the motor, a first auxiliary piece driven by the motor and the transmission mechanism, and a second auxiliary piece connected with the shell. An accommodating space for at least partly accommodating workpieces is arranged between the first auxiliary piece and the second auxiliary piece, and at least one of the first auxiliary piece and the second auxiliary piece is provided with a cutting blade. The transmission mechanism comprises a motion converting mechanism for driving the first auxiliary piece to cut the workpiece relatively to the second auxiliary piece, wherein the first auxiliary piece pivots around a first pivotal axis relatively to the second auxiliary piece. According to the tree trimmer, the first auxiliary piece pivots around the first pivotal axis relatively to the second auxiliary piece, therefore, the tree trimmer can cut trees more stably and has stronger cutting capability.

Description

technical field [0001] The invention relates to a pruning machine. Background technique [0002] At present, the structure of the pruning machine mainly uses the relative reciprocating motion of two blades to cut. Its function is to cut the branches of trees and flowers. Compared with the manual pruning scissors, it has the advantages of reducing work intensity and improving work Features that increase efficiency and improve work safety. A kind of pruning knife disclosed as Chinese Patent No. 99213524.9, which adopts a fixed blade and a moving blade that moves forward and backward relative to the fixed blade to form a cutting edge, so the cut branches are not easy to slip out of the edge, and at the same time The movable and fixed blades are in a linear motion state when they work, and will not increase the volume of the whole machine, which is convenient for cutting a single branch from the bushes. [0003] However, there are deficiencies in this type of pruning machine. ...
