Detailed Description

The following are specific embodiments of the present utility model and the technical solutions of the present utility model will be further described with reference to the accompanying drawings, but the present utility model is not limited to these embodiments.

As shown in fig. 1 to 4, the present utility model can be realized by the following embodiments: a single-shot and continuous-shot switching structure of a nail gun comprises a nail gun main body 1, wherein a trigger 3 is arranged on the nail gun main body 1, and a trigger reed 31 is arranged in the trigger 3.

The switcher component 2 is arranged in front of the trigger 3, the switcher component 2 takes the shell 21 as a frame, a mounting groove 211 is formed in the shell 21, a switching wheel 22 is arranged in the mounting groove 211, a shifting block 221 is arranged on the outer wall of the switching wheel 22, and a user can conveniently shift the switching wheel 22 in a single-click and continuous-click mode; the switching wheel 22 is internally and coaxially provided with a switching shaft 23, the switching shaft 23 is internally provided with a contact bar 24, one part of the contact bar 24 extends into the switching shaft 23, the other part extends out of the eccentric position of the end face of the switching shaft 23, and when the switching shaft 23 rotates, the Y-axis of the contact bar 24 changes to realize the switching between the single-shot and the continuous-shot of the nail gun.

As shown in fig. 4 and 5, a bump 222 is disposed on the inner wall of the switching wheel 22, a groove 231 is disposed on the switching shaft 23, and the bump 222 is abutted with the groove 231. The protrusion 222 and the groove 231 play a role in key slot connection, so that when the dial block 221 is dialed, torque is transmitted to the switching shaft 23, and synchronous rotation of the switching shaft 23 and the switching wheel 22 is ensured.

As shown in fig. 5 and 6, two limiting blocks 223 are provided on the switching wheel 22, and two corresponding limiting grooves 211a are provided on the mounting groove 211 of the housing 21. The limiting groove 211a and the limiting block 223 limit the rotation of the switching wheel 22 to a certain extent, and the switching wheel 22 can be rotated by a larger torque, so that the phenomenon that the mode is not switched in place due to the fact that the switching wheel 22 is touched by mistake in the working process is prevented, and the normal operation of the nail gun main body 1 is influenced; while also preventing the shift wheel 22 from being deflected by torque from the contact strip 24 due to multiple firings of the staple gun in the burst mode.

As shown in fig. 3, the front end of the contact bar 24 is a "U" shaped end 241, and the "U" shaped end 241 is inserted into the switching shaft 23 to hook the inside of the switching shaft 23. The U-shaped end 241 of the contact strip 24 can increase the contact area of the contact strip 24 and the switching shaft 23, so that the contact strip 24 transmits force to the switching shaft 23, the contact strip 24 is prevented from being deformed due to stress, the firing function of the nail gun cannot be normally operated, and the service lives of the switching shaft 23 and the contact strip 24 are prolonged.

As shown in fig. 1, the nail gun body 1 is provided with a mode identifier 11 at the switcher assembly 2, which facilitates the user to grasp which mode the nail gun is in, while facilitating the discrimination of whether the nail gun is malfunctioning.

As shown in fig. 3 and 4, a fixer 4 is arranged outside the switching shaft 23, and the fixer 4 guides the switching shaft 23 to axially move so that the nail gun can normally fire; the switching shaft 23 is provided with a limiting plate 232, and a compression spring 5 is arranged outside the switching shaft 23 between the fixer 4 and the limiting plate 232, and the compression spring 5 enables the switching shaft 23 to reset after being pushed by the trigger reed 31 to move, so that the next firing is prepared.

The working principle of the utility model is as follows: before the nail gun is fired, the shifting block 221 of the switching wheel 22 is shifted, so that the shifting block 221 points to the single-firing mode identifier 11 or the continuous-firing mode identifier 11 of the nail gun main body 1, the switching wheel 22 synchronously rotates with the switching shaft 23 in the rotating process, and the contact strip 24 contacted with the trigger 3 stretches out at the eccentric position of the switching shaft 23, so that the Y-axis position of the contact strip 24 is changed when the switching shaft 23 rotates, and the contact stroke of the contact strip 24 and the trigger reed 31 is changed when the nail gun is fired, so that the firing mode of the nail gun is changed.

The specific embodiments described herein are offered by way of example only to illustrate the spirit of the utility model. Those skilled in the art may make various modifications or additions to the described embodiments or substitutions thereof without departing from the spirit of the utility model or exceeding the scope of the utility model as defined in the accompanying claims.

Although various terms are used more herein, the use of other terms is not precluded. These terms are used merely for convenience in describing and explaining the nature of the utility model; they are to be interpreted as any additional limitation that is not inconsistent with the spirit of the present utility model.
