Low-branch scissors

Abstract

The invention discloses a pair of low-branch scissors and relates to the field of equipment for trimming of a garden. The pair of low-branch scissors comprises a casing as well as a blade mechanism, a transmission mechanism and a drive mechanism which are arranged in the casing, wherein one end of the transmission mechanism is in transmission connection with the drive mechanism, and the other end of the transmission mechanism is in transmission connection with the blade mechanism; the blade mechanism comprises an upper blade and a lower blade which are rotationally connected, and a blade locking gear and an anti-rotating spring piece which are matched with each other are arranged in the connecting position of the upper blade and the lower blade; the transmission mechanism comprises a ball screw and a ball screw nut nested on the ball screw; the ball screw and the drive mechanism are in universal connection, a bearing block and a bearing block support which are matched mutually are arranged in the connection position, and the bearing block is arranged in the bearing block support and can swing in the bearing block support. The service life of the blades can be prolonged within a certain wear range by adjusting the travel of the upper blade, and the blades are simpler and more convenient to replace; the problem of high probability of breakage of the ball screw of the transmission mechanism is solved by the aid of the design of the swingable bearing block, and accordingly, the low-branch scissors are more durable and practical.

Description

technical field [0001] The invention relates to the field of garden pruning equipment, in particular to a low-branch shears. Background technique [0002] Electric low-branch scissors, as a garden tool, are small in size and easy to carry, and are a commonly used tool in gardening pruning. This type of electric low branch scissors includes a movable blade and a fixed blade, the fixed blade is fixedly installed on the casing, the movable blade is rotatably connected to the fixed blade, and the movable blade is driven by the motor through the transmission mechanism to reciprocate and swing, thereby implementing shear action. [0003] On the one hand, during the use of low-branch shears, the fixed blade is mainly responsible for supporting, and the movable blade is responsible for cutting, and the cutting edge angle of the movable blade is small, so the movable blade is relatively easy to wear, and the wear of the movable blade will affect the cutting efficiency and Therefore...
