Embodiment Construction

[0020] Such as figure 1 As shown, it is Embodiment 1 of the present invention. The anti-stall electric pruning shears include a motor, a blade and a motor control circuit. The motor control circuit is used to supply a driving current to the motor, and also includes a motor control circuit electrically connected The detection device is used to detect the current passing through the motor in the working state. When the detection device detects that the current passing through the motor in the working state exceeds the set value, the motor control circuit controls the motor to reverse periodically, so that the blade is reversed to release the blade from being locked. stuck state. Specifically, the detection device is a detection resistor 1 connected in series in the positive and negative circuit of the drive motor to detect the current passing through the motor in working state, and the detection resistor is electrically connected to the motor control circuit; the motor control c...

Abstract

The invention discloses anti-jamming electric pruning scissors, which comprise a motor, blades, a motor control circuit and a detection device. The motor control circuit is used for supplying drive current to the motor. The detection device electrically connected with the motor control circuit is used for detecting rotation speed of the motor or detecting current flowing through the motor in operation. When the detected rotation speed of the motor is not matched with a preset value or the current flowing through the motor in operation exceeds a preset value, the detection device starts the motor control circuit to control the motor to rotate reversely and periodically, so that the blades are drawn back and freed from jamming. The anti-jamming electric pruning scissors can be used for simply, quickly and effectively solving the problem of jamming of the pruning scissors.

Description

technical field [0001] The invention relates to electric tools, in particular to electric pruning shears. Background technique [0002] When the pruning shears (high-branch shears) are working, when the branches are too thick, or many branches get stuck in the middle of the blade at the same time, the blade will be stuck. At this time, it is necessary to clean up the stuck branches before continuing to work. This cleaning work is very difficult, especially on high-pruning shears, where it is very difficult to clean out branches where hands cannot reach. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an anti-stall electric pruning shears, which can simply, quickly and effectively solve the problem of stalling of the pruning shears. [0004] In order to solve the above-mentioned technical problems, the present invention adopts the following technical solutions: a kind of anti-lock electric pruning shears, includ...
