Pruner

Abstract

The invention belongs to garden maintenance equipment and specifically relates to a pruner. The pruner comprises a machine body, blades, a motor, a handle and a switch, wherein the blades are divided into an upper layer and a lower layer, the upper and lower layers of blades move back and forth to form a shear action, the motor drives the blades to move by a transmission mechanism, and the motor is installed in the machine body; and the handle is installed outside the machine body, the switch is installed on the handle, the switch is used to control starting and stopping of the motor, partial structures of the blades are located in the machine body, cutting edges of the blades are extruded and extend to exterior of the machine body, and an anti-locking device is disposed between the motor and the blades. According to the invention, an integral eccentric wheel in a traditional pruner is designed into a split structure; a limited locking device is added; and when foreign matters are clamped by the blades of the pruner, the limited locking device can eliminate limit to the movable eccentric wheel, so that loads of the motor can be reduced, and motor damage can be prevented.

Description

technical field [0001] The invention belongs to garden maintenance equipment, in particular to a pruning machine. Background technique [0002] The pruning machine is one of the important equipment for garden maintenance. It is mainly used to trim the branches and leaves of shrubs to make them look regular. The pruning machine is mainly composed of upper and lower layers of blades. The upper and lower layers of blades are equipped with serrated blades. The two layers of blades are driven by motors to reciprocate, so as to realize the shearing action between the blades. However, the defect of the pruning machine in the prior art is that when the pruning machine encounters some bushes with thick branches, or there are hard objects such as sarcoma on the branches, it is easy to cause the pruning machine to be stuck, which will cause the motor to Overload can even cause damage to the motor in severe cases; on the other hand, since pruning machines generally use one-way rotary m...

However, the defect of the pruning machine in the prior art is that when the pruning machine encounters some bushes with thick branches, or there are hard objects such as sarcoma on the branches, it is easy to cause the pruning machine to be stuck, which will cause the motor to Overload can even cause damage to the motor in serious cases; on the other hand, since the pruning machine generally uses a one-way rotary motor, when a hard object is stuck between the blades, it is difficult to separate the blades to remove foreign objects
