Hydraulic Assisted Garden Shears

Abstract

The invention provides a hydraulic power assisted garden shear which comprises two shear half portions which are hinged each other. Each shear half portion comprises a cutter head and a cutter handle,the cutter handles comprise main rods and holding portions, shaft channels are formed in the main rods, the upper ends of the shaft channels are closed, the lower ends of the shaft channels penetratethe lower end surfaces of the main rods, the holding portions comprise porous cylinders, through holes are distributed in the periphery walls of the porous cylinders, each porous cylinder extends outan oil conveying rod inserted into the corresponding shaft channel upwards along the axis direction of the porous cylinder, sliding plungers are connected at the ends of the oil conveying rods, oil conveying shaft holes communicated with the shaft channels and the porous cylinders are formed in the oil conveying rods and the sliding plungers, cylindrical cavities can be radially deformed and formed in the outer side of the porous cylinders in a surrounding manner, mutually communicated hydraulic oil is closed in the cylindrical cavities, the porous cylinders, the oil conveying shaft holes andthe shaft channels, and sleeves are arranged on the periphery surfaces of the main rods in a sleeving manner and fixedly connected at the upper ends of the porous cylinders. When trimming resistanceis high, the garden shear can automatically extend force arms, trimming difficulty is reduced, and a trimming process is easier.

Description

technical field [0001] The invention relates to the field of garden tools, in particular to a self-garden shear. Background technique [0002] In the process of landscaping maintenance, it is often necessary to use garden shears to prune branches; and there are many kinds of plants in the garden, and the branches of various plants are often different, so when using fixed garden shears for pruning, encounter relatively strong Branches, the pruning process is often more difficult. Contents of the invention [0003] In view of the above problems, the purpose of the present invention is to provide a hydraulic power-assisted garden shears, which can automatically extend the force arm when the pruning resistance is relatively large, so as to reduce the difficulty of pruning and make the pruning process more labor-saving. [0004] The technical solution adopted by the present invention to solve the technical problem is: the hydraulic power-assisted garden shears include two scis...
