Detailed Description
A hand-held nail-shooting fastening tool is a device for shooting nails into workpieces by pushing a piston through closed high-pressure gas and pulling a hammer back to an initial position through a motor and a reduction gearbox transmission mechanism, and comprises a gun nozzle, wherein a striking rod is arranged behind the gun nozzle and is arranged in a nailing seat, and a hammer is arranged behind the nailing seat.
Specifically, the striking rod 2 and the gun nozzle 1 are screwed together to form a sliding pair, and move in the guide rail 3-1 of the nailing seat 3. The connecting shaft 14 passes through the hole 2-3 of the striking rod 2 and the hole 3-2 of the nailing seat 3, is connected with the contact rod 2 by a clamping ring 17 and moves back and forth along with the contact rod 2, and the other end of the connecting shaft 14 is fixedly provided with a magnetic disk 15. The connecting shaft 14 is provided with a striking spring 16 between the hole 2-3 of the striking rod 2 and the hole 3-2 of the nailing seat 3, so that the striking rod 2 can be normally reset after finishing the action. The connecting shaft 14 is also a guide rail of the impact spring 16, so that deformation failure of the impact spring 16 is avoided.
In order to avoid interference with the ratchet 11-1 on the firing pin 11 when the tool is fired, a containing cavity 2-1 for containing the ratchet 11-1 is designed on one side of the striking rod 2, and the containing cavity 2-1 is communicated with the nail shooting hole 2-2.
In a normal state, the magnetic disk 15 is spaced from the hall switch 10, so that the motor is not operated when the switch of the motor 6 is pressed. When the tool shoots nails, the components of the striking rod 2 and the gun nozzle 1 contact the surface of a workpiece and are pressed down, the magnetic disk 15 on the connecting shaft 14 is driven to approach the Hall switch 10, so that the Hall switch 10 is triggered, and the motor can normally work when the switch of the motor 6 is pressed, so that a safety function is realized.
When the striking rod 2 contacts the surface of a workpiece and is pressed down, the two insertion openings 2-7 of the nail inlet 2-6 are inserted between the plastic rows 18-1 of the first and second striking nails, so that the plastic rows 18-1 of the first striking nail are completely surrounded by the nail shooting holes 2-2 of the striking rod 2, and the striking nail is shot out along the nail shooting holes 2-2 after being struck, and the nail shooting holes 2-2 are an integral hole, thereby avoiding the occurrence of the phenomenon of clamping nails.
The front end of the nailing seat 3 is provided with two pin holes 3-3, a locating pin 13 is inserted into the pin holes, and two ends of the locating pin are respectively fixed by small sealing rings 12. After the firing is finished, the striking rod 2 is reset under the action of the striking spring 16, and the boss 2-4 on the striking rod 2 contacts the positioning pin 13, so that the striking rod 2 is limited.
The small boss 4-3 on the nail pusher assembly 4 can gradually move towards the nailing seat 3 along with the reduction of the nail, when the last two to three nails are left, the small boss 4-3 enters the notch 2-5 on the striking rod 2, so that the striking rod 2 cannot be pressed down, the magnetic disk 15 cannot approach the Hall switch 10, the motor cannot be started, and normal nail shooting cannot be performed, thereby realizing the protection function of no nail and no firing.
