Abstract

The invention relates to an electric lopping device. The electric lopping device comprises pruning shears (1), a driving device (2) and a support frame (3), wherein the pruning shears (1) comprise anupper shear stem (11), a lower shear stem (12), an upper lopping edge (13), a lower lopping edge (14) and a lopping stem spring (15) located between the two lopping stems; the driving device (2) comprises a connecting rod (21), a driving rod (22), a motor rotating shaft (23), a rotating shaft transverse rod(24) and a motor (25); the support frame (3) comprises a front support rod (31), a rear support rod (32) and a bottom plate (33); the top end of the front support rod (31) and the top end of the rear support rod (32) are connected, and the lower ends of the front support rod (31) and the rear support rod (32) are fixed to the bottom plate (33) to form a triangle; the middle of the pruning shears(1) is fixed to the upper part of the support frame (3); and the driving device (2) drives theupper lopping stem (11) to move up and down so as to drive the lower lopping edge (14) and the upper lopping edge (13) to close or open. The motor is used for driving the pruning shears, so that theworking efficiency is improved.

Description

technical field [0001] The invention relates to an electric pruning device, in particular to a pruning device which drives the pruning shears by pedaling, and belongs to the field of forestry machinery. Background technique [0002] Pruning shears are commonly used tools for forestry pruning, but pruning shears are generally held by the handle; when the workload is large and the use time is long, it is more laborious; especially with large scissors, it is difficult to operate the scissors with one hand. Both hands need to hold the scissor handle, which is inconvenient when the workload is heavy, and the work efficiency is not high. [0003] After searching the Chinese patent document publication number "CN107734963A", the scissors including the first cutting part and the second cutting part provide no [0004] The movement of laminated or flat spring elements with or with very little friction to avoid noise or wear; the scissors have a lot of operation, and it is still rela...
