AI Technical Summary
Technical Problem
Existing electric pruning shears may result in users being distracted and accidentally cutting off their left-hand fingers, lacking an effective protection mechanism.
Method used
Infrared and temperature sensors are installed on the electric pruning shears. By sensing the proximity of the left hand to the shears, the motor is stopped to prevent accidental cutting. Combined with mechanical structures such as locking posts, pressing plates, and limiting cones, the safety of button operation is ensured.
Benefits of technology
It effectively avoids cutting the left hand fingers due to distracted operation, improves safety, and ensures that the electric pruning shears will not malfunction in abnormal conditions.

Abstract
The utility model relates to the technical field of electric branch shears, and discloses an electric branch shear capable of preventing fingers from being cut by mistake, which comprises a shear, an infrared sensor arranged on one side of the shear, a temperature sensor arranged on the surface of one side, close to the infrared sensor, of the shear, a start button arranged inside the shear, and a lock hole arranged at the bottom of the start button. An extrusion groove is formed in one side of the lock column, an extrusion plate is slidably connected into the extrusion groove, an adjusting mechanism used for adjusting the extrusion plate is arranged on one side of the extrusion plate, a sliding groove is formed in one side of the extrusion plate, and a restraining mechanism used for restraining the extrusion plate is arranged in the sliding groove. Through the arrangement of the sensor, the left hand can be protected so as to avoid the phenomenon of finger cutting, the sensor is connected with the controller in the scissors, so that after the controller receives information, an instruction can be given to the motor driving module, and the motor stops running; therefore, the phenomenon that the fingers are sheared by the scissors is avoided.
