Abstract

The invention discloses a pair of pruning shears. The pair of pruning shears comprises a shell, a knife bar assembly, a driving device and a transmission mechanism, wherein the shell comprises a first shell and a second shell; the transmission mechanism is accommodated in the first shell; the knife bar assembly is connected with the first shell; the driving device is accommodated in the second shell; a main handle is arranged between the first shell and the second shell. According to the pruning shears, the first shell is connected with the knife bar assembly and is used for accommodating the transmission mechanism, the second shell is used for accommodating the driving device, and the main handle is arranged between the first shell and the second shell, so that the fore-and-aft gravity balance of the machine body of the pruning shears facilitates the operation of a user.

Description

technical field [0001] The present invention relates to a kind of pruning shears. Background technique [0002] The main handle of the existing pruning shears is arranged at one end of the housing, and the motor is arranged in the housing between the main handle and the blade assembly. When holding the pruning shears, since the gravity is biased toward one end of the blade assembly, the front and rear gravity is unbalanced, which is inconvenient for the user to operate. Therefore, the existing pruning shears are also provided with an auxiliary handle near the blade assembly on the housing, and the user holds the main handle and the auxiliary handle with both hands, so as to achieve the purpose of gravity balance. [0003] However, in some cases, the user needs to hold the pruning shears with one hand. At this time, no matter holding the main handle or the auxiliary handle, the gravity of the pruning shears cannot be balanced. Cut to improve. Contents of the invention ...
