Abstract

An electric nail gun comprises a casing which comprises a transverse hammer head section and a vertical handle section. A hammer head is slidably arranged in the front of the inside of the hammer head section, a motor is arranged inside the handle section and connected with a transmission mechanism, the rear end of the hammer is connected with a swing mechanism pushing the hammer head, and the swing mechanism is connected with the transmission mechanism through a clutch mechanism. When the electric nail gun is used, power is transmitted to the wing mechanism by the transmission mechanism driven by the motor, and the hammer head is driven by the swing mechanism to swing back and forth in a reciprocated manner to strike nails. Since the swing mechanism is connected with the transmission mechanism through the clutch mechanism, the swing mechanism and the transmission mechanism can be separated if the machine idles, and the motor is operated under the unloaded state so that energy of batteries can be saved. When the electric nail gun is used for striking nails, the swing mechanism and the transmission mechanism are combined to smoothly realize nail striking. When the machine idles, an impact mechanism is not operated, the motor is operated under the unloaded state, and thereby energy of the batteries can be saved.

Fig. 1 is the cutaway view of the utility model.

(5) specific embodiment

Below in conjunction with the accompanying drawing and the specific embodiment the utility model is done further explain.

A kind of electric nail gun comprises casing 1, and described casing 1 comprises horizontal tup section and vertical handle section; In described tup section, its front portion is slidingly equipped with tup 2; In described handle section, be provided with motor 3, described motor 3 is connected with transmission mechanism, and the rear end of said tup 2 connects the swing mechanism of push-and-pull tup 2, connects through clutch between said swing mechanism and the transmission mechanism.

In the present embodiment, the concrete structure of swing mechanism, transmission mechanism and clutch and connected mode are:

The described tup 2 outer sliding sleeves 4 that are slidingly equipped with; Be provided with stage clip 5 between the front portion of said tup 2 and the sliding sleeve at rear 4: the front portion of said tup 2 has the tup step; The front end of said stage clip 5 withstands on the described tup step, and the rear end of said stage clip 5 withstands on the front end face of said sliding sleeve 4.

Be connected with a shift fork 6 on the described sliding sleeve 4; Said tup 2 belows are provided with a horizontal power transmission shaft 7; Be with an Oscillating lever bearing 8 on the described power transmission shaft 7, the fork 9 of said Oscillating lever bearing 8 is hinged with the rear end of said tup 2, and the front end of this Oscillating lever bearing 8 is corresponding with the bottom of said shift fork 6.

The top of said shift fork 6 is enclosed within on the described sliding sleeve 4, and the bottom of said shift fork 6 is enclosed within on the described power transmission shaft 7, convexes with a step lasso 10 on the described sliding sleeve 4, and described step lasso 10 is positioned at the place ahead of said shift fork 6.Also have a bearing pin 11 in the described casing 1, the lower end of said shift fork 6 is enclosed within on the described bearing pin 11.
