Fig. 2 is a schematic structural diagram of the driving mechanism of the present invention.

Detailed Description

As shown in fig. 1 and 2, an electric nailing gun comprises a shell 1, a gun head 2 and a nail groove 3, wherein the nail groove 3 is connected on the gun head 2, and the gun head 2 is fixedly connected with the shell 1, and is characterized in that: a driving motor 11, a first cylinder 12 and a second cylinder 13 are arranged in the shell 1, an output shaft of the driving motor 11 is connected with a reduction gear 14, an output end of the reduction gear 14 is connected with a piston of the first cylinder 12 through a crankshaft 15 and a connecting rod 16, the first cylinder 12 is communicated with the second cylinder 13, the diameter of the first cylinder 12 is larger than that of the second cylinder 13, the piston of the second cylinder 13 is connected with a firing pin 6, and one end of the firing pin 6 is matched with the gun head 2; the handle 10 of the shell 1 is also provided with a battery 5 and a control switch, the battery 5 supplies power for the driving motor 11, and the control switch controls the power-on or power-off of the driving motor.

The first cylinder 12 and the second cylinder 13 are arranged in parallel in the axial direction, one end parts of the first cylinder 12 and the second cylinder 13 are communicated with each other, the connecting rod 16 and the firing pin 6 are respectively arranged at the other ends of the first cylinder 12 and the second cylinder 13, and the motor 11 is arranged in parallel with the nail groove 3 in the axial direction.

the utility model discloses the working process is such: the control switch is pressed down, the driving motor is electrified to rotate, an output shaft of the driving motor amplifies torque through the reduction gear, the crankshaft and the connecting rod convert the amplified rotating torque into thrust for driving a piston of a first air cylinder, the first air cylinder transmits pressure to a second air cylinder, and the difference between the cylinder diameters of the two air cylinders is large, so that the movement speed of the piston of the first air cylinder and the movement and cylinder diameter ratio of the piston of the second air cylinder are in inverse proportion, the larger the difference between the cylinder diameters is, the larger the amplification factor of the movement speed is, the higher the speed is compared with the cylinder diameter ratio of the two air cylinders, and the high-speed impact of a.
