Nail gun with reliable working

Abstract

The invention provides a nail gun with reliable working. The main gun comprises a gun shell, a trigger, a motor, a first air cylinder, a second air cylinder, a crank, a connecting rod, a nailing assembly and a nail conveying assembly. The second air cylinder is located in the first air cylinder. A first piston is arranged in the first air cylinder. A second piston is arranged in the second air cylinder. The connecting rod is connected with the first piston in a transmission mode. The motor is connected with the crank in a transmission mode through the transmission mechanism and drives the first piston to move in the first air cylinder in the axial direction through the connecting rod. The nail gun comprises a triggering switch. A triggering ejecting rod is arranged on the trigger. The transmission mechanism comprises a decelerator, a transmission shaft and a sleeved cam. A self-locking ejecting rod is arranged between the cam and the triggering switch. When the cam moves to a high point, the self-ejecting rod is pushed to trigger the triggering switch and separate the triggering ejecting rod from the triggering switch. When the cam moves to a low point, the self-locking ejecting rod separates from the triggering switch. Through the mechanical structure, the motor is controlled to complete a cyclic action, and working reliability of the main gun is well guaranteed.

Description

technical field [0001] The invention relates to the field of electric tools, in particular to a reliable nail gun. Background technique [0002] A nail gun is a tool that can quickly drive nails into objects such as wood. It is very commonly used in the woodworking field, and an air nail gun is one of the more commonly used types of nail guns. Existing air nail guns generally use air pipes to connect to external compressed air sources with a certain pressure as power to drive the striker to move, that is, another set of equipment that generates high-pressure air sources, such as an air compressor, is required to cooperate. There will be a lot of inconvenience. [0003] There is an existing nail gun that sets a large cylinder and a small cylinder in the casing, and uses the pressure difference generated by the volume difference between the large and small cylinders to perform impact nailing, which can well solve the above problems. But it still has certain problems, such as...

AI Technical Summary

Problems solved by technology

But it still has certain problems, such as by setting a position sensor to detect the position of the piston to ensure that the piston stops and is ready for the next striker movement when it moves to a certain position, that is, it is electronically detected and controlled, but This kind of electronic detection and control will have instability, which will affect the reliability of nailing, that is, the working reliability of the nail gun is not good
