Problems solved by technology

At the same time, there is a limitation in this solution, that is, MCU failure handling
When the MCU is disturbed and fails, it may issue a wrong command, that is, when the switch of the pruning shears is not pressed, the MCU sends a command to make the motor rotate, thereby driving the blade to perform a cutting action. This wrong command The resulting misoperation of the electric scissors will most likely injure the user

Embodiment Construction

[0013] specific implementation plan

[0014] There are various shapes and types of electric scissors. In this embodiment, pruning shears are used as an example. refer to figure 1 , The pruning shears 10 include a casing 1 and a motor 2 (not shown) installed in the casing 1 . The cutter part of pruning shears 10 is made up of fixed blade 3 and movable blade 4, wherein, fixed blade 3 is fixedly installed relative to casing 1, and movable blade 4 is connected with motor 2 through a power transmission device. A knife edge 5 is formed between the fixed blade 3 and the movable blade 4 . The switch 6 is installed on the casing 1 . In order to be suitable for different workplaces, the pruning shears 10 are powered by a battery pack, which can be installed at the end of the casing 1 (not shown in the figure).

[0015] refer to figure 2 , which shows a block diagram of the circuit principle of the first embodiment of the control system of the pruning shears 10 . In order to meet ...

Abstract

The invention relates to a control method of electric clippers, which comprises the following steps of: pressing a switch to ensure that a power supply module works and a microprocessor starts; when the switch and the microprocessor are simultaneously effective output, controlling the motor to operate by a control system; when the switch is released, maintaining the power supply module to be switched on by the microprocessor, and controlling the motor to reversely rotate by the control system to drive a movable blade to spread; and when the movable blade is spread to the maximum position, controlling the motor to stop rotating by the microprocessor, and switching off the power supply module. Only when the switch and the microprocessor are effective output simultaneously, the control controls the motor to operate, therefore, the electric clippers with the control method effectively avoid the risk caused because the microprocessor becomes invalid to send an error command.

Description

technical field [0001] The invention relates to a control method of electric scissors, in particular to a safety control method of electric scissors. Background technique [0002] As a category of electric tools, electric scissors include electric scissors for cutting thick fibers such as carpets, electric scissors for cutting cables, and electric scissors for pruning branches. These electric scissors usually consist of a fixed blade and a movable blade forming a cutting edge between the two blades. The movable blade swings back and forth under the forward and reverse drive of the motor, so that the knife edge is opened and closed continuously. In order to reduce accidents during use, electric scissors must meet the requirements of safety standards. Taking pruning shears for pruning branches as an example, the safety standard stipulates that once the switch is disconnected, the blade of the pruning shears should automatically open to the maximum to ensure safety.
