Background
The existing electric nail gun has the working principle that after being electrified, a motor starts to rotate to drive a speed reducer, a punch slide block is driven by a transmission device to slide from the lowest point of a stroke to the highest point to compress an elastic element, and when the highest point of a nailing stroke is reached, the restoring force of a spring pushes the punch slide block to realize the nailing action. Therefore, after the electric nail gun is started, the punch slide block needs to be lifted to the highest position of the stroke to realize the nailing action, corresponding waiting time is brought to an operator, the nailing speed is slow, and the nailing frequency is low. The existing nail gun has poor nailing effect, and needs to be operated by two hands because the nailing is not deep enough (nails are overflowed).

Furthermore, the proximity switch is arranged at the position 5-10mm away from the highest position of the nailing stroke below the stroke of the punch slide block, and the energy storage release mechanism is an intermittent mechanism.
Furthermore, the intermittent mechanism is a sector gear which can be driven by a motor and a rack which can be driven by a punch slide block, and the sector gear is meshed with and separated from the rack in the rotating process, so that compression energy storage and release of the elastic element are realized.

FIG. 1 is a schematic illustration of an electric nailer in a preferred embodiment of the present invention;
FIG. 2 is a partial cross-sectional view of an electric nailer in a preferred embodiment of the present invention;
fig. 3 is a schematic view of the assembly of the drive gear, sector gear and rack in a preferred embodiment of the utility model.
Detailed Description
The technical contents of the preferred embodiments of the present invention will be more clearly and easily understood by referring to the drawings attached to the specification. The present invention may be embodied in many different forms of embodiments and the scope of the utility model is not limited to the embodiments set forth herein.
As shown in fig. 1-3, the present invention provides an electric nail gun 100, which comprises a housing 10, wherein the housing 10 is provided with a motor 1 for providing power, a speed reducer 2, a gear 21, a punch slide block 3, a striker 31, a transmission gear 4 for transmitting power, a sector gear 41, a rack 5, an elastic element 6, a nail cabin 7 and a proximity switch 8. When the nailing machine works, the torque output by the motor 1 is reduced by the speed reducer 2 and then output by the gear 21, the gear 21 drives the transmission gear 4, when the transmission gear 4 rotates, the sector gear 41 fixed on the transmission gear rotates along with the transmission gear, the sector gear 41 is meshed with the rack 5 to drive the punch slide block 3 to compress the elastic element 6 backwards, and after the elastic element 6 is compressed until the sector gear 41 is separated from the rack 5, the punch slide block 3 can drive the striker 31 to nail towards the nail cabin 7 under the action of the elastic restoring force of the elastic element 6 to finish a nailing action.
A proximity switch 8 is arranged at the position 5-10mm away from the highest position of the nailing stroke below the stroke of the punch slide block 3. After completing one nailing action, if the button switch is released, the sector gear 41 will rotate again under the action of the motor to engage with the rack 5, thereby compressing the resilient member 6 again until the punch slide 3 is moved to the position of the proximity switch 8. The proximity switch 8 senses the punch slide block 3, namely, the power of the motor is cut off, so that the punch slide block 3 stays at a stroke position above the proximity switch 8 under the resistance action of the transmission gear, the speed reducer and the motor. That is, after the electric nail gun 100 releases the starting switch, the elastic element 6 is in a compressed state under the action of the proximity switch 8, and the punch slide block 3 always stays at the position 5-10mm away from the highest position of the nailing stroke for the next nailing, so that the waiting time is shortened, and the triggering can be realized once being triggered. The electric nail gun has the advantages of high nailing speed, more compact structure, higher response speed, better nailing effect and simpler operation.
In the present embodiment, the speed reducer 2 is a planetary speed reducer, but other speed reducing structures in the prior art can be adopted, and the present invention is not intended to limit the speed reducer.
In the present embodiment, the elastic element 6 is a compression spring, but it may be another type of elastic element in the prior art, and the present invention is not intended to limit the present invention.
In the present embodiment, the proximity switch 8 is a magnetic proximity switch, but may be other types of proximity switches known in the art, and the present invention is not intended to be limited thereto.
The foregoing detailed description of the preferred embodiments of the utility model has been presented. It should be understood that numerous modifications and variations could be devised by those skilled in the art in light of the present teachings without departing from the inventive concepts. Therefore, the technical solutions available to those skilled in the art through logic analysis, reasoning and limited experiments based on the prior art according to the concept of the present invention should be within the scope of protection defined by the claims.
