It is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments in the present invention without creative efforts are within the scope of the present invention.

1 to 5, an electric nailing mechanism includes: a power transmission 1, a striker 4, a rotation output mechanism 6, and a gun body casing 7, and a gun body casing 7 for accommodating the power transmission 1, the striker 4. The spring 5 and the rotary output mechanism 6; the power transmission 1 includes a driven outer ring 2 and an active inner ring 3, and a one-way rotation restricting portion is provided between the driven outer ring 2 and the active inner ring 3, and the one-way rotation restriction The portion cooperates with the outer ring and the inner ring to lock or unlock between the driven outer ring 2 and the active inner ring 3; when the driven outer ring 2 and the active inner ring 3 are locked, the active inner ring 3 Synchronously rotating with the driven outer ring 2 lock, driving the striker 4 to rise to compress the spring 5; when the driven outer ring 2 and the active inner ring 3 are unlocked, the compressed spring 5 is reset to drive the striker 4 to lower the nail; The rotation output mechanism 6 is connected to the active inner ring 3, and the rotation output mechanism 6 provides rotational power; the bottom end of the striker 4 is synchronously connected with the driven outer ring 2, and the striker 4 is further provided with a spring 5, when the striker 4 rises, The spring 5 is compressed, and the deformation energy of the spring 5 is applied to the striker 4 so that when the striker 4 is lowered When the compression of the spring 5 is released, the deformation can be released, and the downward impact force of the striker 4 is improved.

In the use state, it outputs power through the rotation output mechanism 6, and the active inner ring 3 rotates, where the rotation direction should be the reverse direction of the driven outer ring 2 and the active inner ring 3, thereby realizing the locking effect, and the active inner ring 3 Rotate to rotate the position at the lowest point (ie, the 0 o'clock position) to the highest point. As shown in FIG. 3, since the reverse rotation, the driven outer ring 2 and the active inner ring 3 are locked, and the driven outer ring 2 is Following the rotation of the active inner ring 3, and the arrangement of the spring 5, the driven outer ring 2 always has a pull-down force (ie, the driven outer ring 2 always has a force that reverses the active inner ring 3) The rotation of the spring 5 is simultaneously achieved. When the active inner ring 3 is rotated to the highest point at the lowest point, it should be a critical point (ie, rotated by 180 degrees), as shown in FIG. At the critical point, 180 degrees of the previous rotation is the locked state. After more than 180 degrees, the slave is driven. The outer ring 2 and the active inner ring 3 are in the same direction of rotation, and become unlocked, and the 180 degrees of the preceding rotation causes the spring 5 deformation to be released, that is, the rotation of the driven outer ring 2 is accelerated, so that the rotation is completely fast. Rotate 180 degrees, rotate to 360 degrees position, that is, fall back to 0 o'clock position, at the same time of rapid rotation, that is, the impact of the fast impact of the striker 4 to achieve the nailing effect, as shown in Figure 5, the driven outer ring 2 rotates back to the At the same time of the 0 o'clock position, the active inner ring 3 is rotated at a constant angle by the rotation speed of the motor 8, and when the driven outer ring 2 is rotated back to the 0 o'clock position, the resetting of the two is achieved, and the rotation is continued.

The rotation output mechanism 6 includes a motor 8 , and the motor 8 is connected to the rechargeable battery 9 . The operation power consumption of the motor 8 is small, so the capacity requirement of the rechargeable battery 9 is also small, which is advantageous for miniaturization of the mechanism and weight and weight preparation. The output end of the motor 8 is provided with a speed reducer 10, and the speed reducer 10 is fixedly connected with the active inner ring 3, so as to facilitate the adjustment of the nailing speed.

A power switch 11 is further disposed between the motor 8 and the rechargeable battery 9. The nailing effect can be realized only by controlling the opening and closing of the motor 8, and the operation is simple and reliable, and no problem such as air pressure is required.

A first limiting portion 16 is disposed on a surface of the striker 4 corresponding to one end of the spring 5. The other end of the spring 5 is disposed with a second limiting portion 17 corresponding to the inside of the gun body casing 7.
