Abstract

The invention provides a pneumatic nailing gun, and belongs to the technical field of electric tools. Through the pneumatic nailing gun, the problem that in order to enable a power piston to be unlocked more stably and reliably, the nailing strength of an existing pneumatic nailing gun is difficult to adjust is solved. The pneumatic nailing gun comprises a shell, wherein a pressurizing cylinder body and a power cylinder body are arranged in the shell, a pressurizing piston is arranged in the pressurizing cylinder body, a power piston capable of being locked when the pressurizing piston pressurizes an inner cavity is arranged in the power cylinder body, a motor can unlock the power piston when the pressurizing piston completes a pressurizing stroke, a pressure relief channel is formed between the power piston and the power cylinder body, the pneumatic nailing gun further comprises a rotational speed control module capable of controlling the rotational speed of the motor, the rotational speed control module adjusts the time required for the pressurizing piston to complete the pressurizing stroke by controlling the rotational speed of the motor, and the rotational speed control module can control the motor to output at least two different rotational speeds. The pneumatic nailing gun can control the nailing strength through the rotational speed of the motor.

Description

technical field [0001] The invention belongs to the technical field of electric tools and relates to a pneumatic nail gun. Background technique [0002] The pneumatic nail gun is composed of the gun body and the nail box. The gun body is composed of the gun shell, cylinder, trigger assembly, firing pin assembly, gun nozzle and bumper assembly, etc., and the pressure difference is formed after the air is compressed by the cylinder. , through the trigger switch to make the striker reciprocate in the cylinder, usually the pneumatic nailing gun is driven by the air pressure in the power cylinder to drive the power piston, and then the steel nail is driven out, so the air pressure in the power cylinder determines the steel nail. strength. [0003] In order to ensure the accuracy of the air pressure value, and thus ensure the accuracy of the driving force of the steel nails, the patent document (application number: 201920866981.6) discloses a multi-functional air nozzle and a con...
