The first conductive metal member 321 and the second conductive metal member 322 are engaged with each other through the engaging component 320, and accordingly the second conductive metal member 322 and the working head 21 are driven to rotate, so that the nailing work is realized. After the user observes that the screw is installed in place, the user releases the pressing on the working head 21, so that the second conductive metal member 322 and the first conductive metal member 321 are bounced open under the action of the elastic member 323, and the corresponding conductive path where the motor 31 is located is also disconnected. When not using, then promote on & off switch 5 to the off-state, drive the contact of switch 4 this moment and move, corresponding switch 4 switches on, and then motor 31 is in the short circuit state, can't switch on work, has guaranteed the security that this drywall gun placed.
When the dry wall gun needs to be frequently used for a long period of time, the operating key 6 is pressed to turn on the operating switch 7, the switch key 5 is pushed upwards to a working state, the upper end of the switch key 5 clamps the hook 61 on the lower end of the operating key 6, the operating key 6 is continuously in a pressed state, namely, the operating switch 7 is continuously in a turned-on state, meanwhile, the switch 4 is always in a turned-off state in corresponding time, and the motor 31 is in a standby state. When the nailing machine is used, a user does not need to press the operation key 6, and only needs to press the working head 21 to electrify and conduct the second conductive metal member 322 and the first conductive metal member 321, so that the control circuit board 1 controls the motor 31 to rotate to complete the nailing work. When the nail is not driven, the pressing of the working head 21 is released. So made things convenient for the use of drywall rifle in automatic continuous shooting time range greatly, simplified the automatic continuous shooting operation of drywall rifle for the user can concentrate on looking over the condition that the screw was squeezed into with attention more, has promoted the nailing effect, has simplified user operation, has promoted user experience.
