Electric nail gun

The invention relates to a nailing device for an electric nailing gun, which provides a stable and reliable practical effect of the electric nailing gun and the nail action.

Press, as shown in the eighth figure, the nailing device of the conventional electric nailer is generally as follows: a motor (70), a push switch (71), the motor (70) has a drive shaft (72), A drive lever (72) is connected with a cam lever (73), and a pusher portion is provided with a nail piece (74), a paddle (75) and a spring (77), the paddle (75) Cooperating with a casing (76) integrally on the outer side of the spring (77), the convex transfer lever (73) is in contact with the paddle (75), so that the paddle (75) is compressed and extended synchronously with the spring (77). Actuated, the nail piece (74) is connected above the paddle (75); the user can actuate the push switch (71) to activate the motor (70) drive shaft (72) to drive the cam lever ( 73) Rotating, the cam lever (73) pushes the paddle (75) by the power of the cymbal, and synchronously compresses the spring (77) to gradually shift in the opposite direction of the pin to store the elastic force; As shown, when the rotational stroke of the cam lever (73) passes over the paddle (75), the paddle (75) is not pushed by the cam lever (73) and bears against the paddle (75). The inner spring (77) immediately releases the spring force; see the tenth figure, the spring (77) is released According to the driving force of the striking plate (74) striking the staple (78), so that the staple (78) to be hit into the work piece.

However, according to the above structure, there is actually the following disadvantage: since the cam lever (73) and the paddle (75) are in contact with the top surface, and the cam lever (73) is formed by a smooth cylinder, when the cam is dialed When the rod (73) and the pick (75) are rotated, the spring force is exerted by the spring (77), and under long-term use, a strong frictional contact is formed between the two, and there is wear and tear. It is easy to cause the nail to be correct.

The designer's main purpose is to use the transmission of the gear and the rack to drive the elastic nailing operation, instead of the existing cam dialing, in view of the lack of the operation of the electric nailing gun. The top smashing nail design of the rod and the plucking wheel is used to obtain a hammering actuating device for the electric nail gun which is effective and stable.

In order to achieve the foregoing objective, the technical means utilized by the present invention is to provide a nailing device for an electric nail gun, comprising a nail gun body, a motor, a push switch, a push nail portion and a spring plate The nail gun body provides the above-mentioned component in the body, the motor is connected to the half moon gear, and the half moon gear is driven by the motor; the nail pushing portion is disposed at the upper end of the nail gun body, and the nail pushing portion is The utility model has a sliding seat and a punching piece, wherein the upper end of the sliding seat bears against the spring plate piece, and the inner edge of the sliding seat is provided with a rack corresponding to the half moon gear, the breaking piece is pivotally connected to the sliding seat, and the shooting piece is pivoted Nested on a guide plate; accordingly, the motor drives the half moon gear to rotate the rack to rotate the slider in the opposite direction of the nail and bend the spring plate, and the toothed stroke of the half moon gear is disengaged from the rack. The spring plate piece immediately displaces the slider and the pin piece in the direction of the nail and strikes the nail, so as to obtain a correct and stable device for the nailing action.

A brief description of the functions that can be obtained by the present invention according to the technical means of the present invention is as follows:

1. The electric nail gun of the present invention is connected to the shaft of the output end of the motor, and the half-moon gear is pivotally actuated. After the motor is started, the half-moon gear is rotated, because the tooth shape of the half-moon gear directly meshes with the sliding seat. The rack is so stable that the transmission between the two is stable, which can improve the nailing effect of the nail gun and reduce the situation of the empty needle or the needle.

2. The nailing device of the electric nailing gun of the present invention is engaged with the sliding seat, and the upper end of the sliding seat is connected with the spring plate piece, so that the tooth shape of the half moon gear meshes with the rack of the sliding seat to transmit power. Time, The transmission components associated with the connection can be synchronized to achieve a stable nailing effect.
