Abstract: Disclosed is a pneumatic nailing gun with an adjustable nailing force, which solves the technical problem that a nailing force adjusting precision of an existing pneumatic nailing gun cannot be kept for a long time. The pneumatic nailing gun comprises a housing and a striking pin, a first cylinder and a second cylinder are further arranged in the housing, and the first air chamber and the second air chamber are communicated with each other through a fully-closed ventilation channel, so that the first air chamber, the ventilation channel and the second air chamber form a pneumatic structure closed relative to the outside, and an air hole capable of keeping the pneumatic structure in communication with the outside is arranged in the pneumatic structure, and a handle capable of adjusting a ventilation capacity between the air hole and the outside is arranged on the housing.

Abstract: The present invention provides a nail gun, which belongs to the field of mechanical technologies, and solves a problem of how to prolong a service life of the nail gun. The nail gun comprises a housing and a driving arm capable, the housing is provided with a stopper and a locking block capable, the locking block is arranged between the stopper and the driving arm, and the locking block is respectively provided with a first locking portion and a second locking portion capable of being pawled in the driving arm; the stopper is capable of abutting against the first locking portion and preventing the locking block from moving relative to the housing to keep the second locking portion pawled with the driving arm, or the stopper is capable of releasing blocking so that the second locking portion is capable of moving and disengaging from the driving arm.

Abstract: A nail gun, comprising a first piston moveably disposed in the first cylinder, a second piston moveably disposed in the second cylinder, a driving ram, a pawl, a linear motion actuator electrically coupled to the control circuit unit, the linear motion actuator capable of driving the pawl to retain or release the driving ram. The adjustment button is configured to select a selected pressure rating of the pressure ratings, during the compression stroke, the pawl retains the driving ram, and the control circuit unit is configured to calculate a predetermined distance value of the second piston and control the second piston to move and form a predetermined compressing pressure in the second working chamber. The control circuit unit is configured to control the linear motion actuator to release the driving ram when the second piston moves the predetermined distance.

Abstract: The nailing machine includes a closed first cylinder and a closed second cylinder, a working chamber of the first cylinder and a working chamber of the second cylinder are communicated with each other. A first piston inside a first cylinder is fixedly connected with a striker that has a locking part. The locking part could be locked by a pawl. The second cylinder is provided with a second piston reciprocated by a motor between a first position and a second position. When the second piston is in the first position, after the first piston moves inward, the pawl snaps at the locking part of the striker. When the second piston is in the second position, the motor drives the pawl to disengage from the locking part. the motor drives the second piston to compress air, and triggers the pawl, achieving the rapid and continuous firing of strip nails.

Abstract: The new invention is a portable tool, specifically directed electric motor driven nail gun. It has a nail push system, also a motor. The motor uses a flywheel as a speed reduction mechanism, the main characteristic is that the drive unit of the driving mechanism is connected to a pitman by a pin axis on one end, and the other end is connected to the pin axis which does the arc movement. The end of the drive unit props up the long slot by a spring and enclosed by the long slot in a sliding movement. The rectilinear reciprocating drive unit is governed by a clutching mechanism mounted on the speed reduction mechanism. The new invention can provide a powerful impacting force. The clutch bar of the driving mechanism has an outer bulge and inner bulge, it controls the tension spring which makes the drive unit impact nails and recover after impacting nails, without any memory of the rotating state.

Abstract: The new invention is a portable electric power tool, specifically directed to driving a fastener into a substrate as an electric motor driven nail gun. It has a bracket, switch, control unit, magazine and nail push system, also a motor which derives its power from a power supply or rechargeable batteries. The motor drive uses a flywheel as a speed reduction mechanism, a main characteristic is that the drive unit of the driving mechanism is connected to a pitman by a pin axis on one end, and connected to the pin axis on the other link which does the arc movement. The other end of the drive unit is connected with a spring and long board to the long slot in a sliding movement. The clutching mechanism of the speed reduction mechanism controls the anvil to do linear movement driven by the rotational motion of the flywheel. The new invention can be slim, simply and easily assembled, and provide a powerful impacting force.
