Specific implementation mode

Below in conjunction with description of the drawings specific embodiment of the present utility model.As shown in Figure 1, Figure 2, Figure 3 shows：It is a kind of electronic Shell 1 based on nailing gun, including one is provided with motor 2, the driving on 2 output shaft of motor in one end of shell 1 Tooth is meshed with the external tooth for the gear ring 3 being rotatably supported in shell 1, and also there are three trapezoid buckle screw rods for rotational support in shell 1 4, the end of each trapezoid buckle screw rod 4 is both provided with the gear being meshed with the internal tooth of the gear ring 3, i.e., when gear ring 3 rotates, Three above-mentioned trapezoid buckle screw rods 4 can be driven while being rotated, the pressure being distributed along 1 length direction of shell is provided in shell 1 Power spring 5, and compression spring 5 passes through the central opening of gear ring 3, and one end of compression spring 3 is withstood on shell 1, and the other end It then withstands in hammer 6, at one end of the hammer 6 far from compression spring 5 is also associated with rifle needle 7, and 7 company of being actively socketed on of rifle needle It is connected in the gun barrel 8 on shell 1, is also mutually furnished with nail clip 9 with the rifle needle 7, gun barrel 8, dress is additionally provided in the lower section of shell 1 The battery case and handle 11 for having battery 10, are provided with the switch 12 that can control 2 working condition of motor on handle 11,

Above-mentioned hammer 6 includes a discoidal ontology 13, and there are three prominent for setting on the excircle of ontology 13 Portion 14, and these three protruding portions 14 are uniformly distributed in a circumferential direction, and it is semicircle that section is both provided on each protruding portion 14 The opening portion 15 of shape is provided with trapezoid buckle screw thread in opening portion 15, and the opening portion 15 on above three protruding portion 14 is divided It does not correspond and is threadedly coupled with three trapezoid buckle screw rods 14, the one end of trapezoid buckle screw rod 4 far from gun barrel 8 is additionally provided with separation Round platform 16, and described separation relatively small one end of 16 diameter of round platform is towards the direction of gun barrel 8, be additionally provided in shell 1 with The sliding rail 17 that the outer wall of one protruding portion 14 matches, when hammer 6 is transported in shell 1 from the direction of gun barrel 8 toward the direction of motor 2 When dynamic, the sliding rail 17 is in contact with the outer wall of a protruding portion 14, and when hammer 6 is interior from the direction of motor 2 in shell 1 When being moved toward the direction of gun barrel 8, sliding rail 17 is not contacted with protruding portion 14, is additionally provided with and is hit close to one end of gun barrel 8 in shell 1 Hammer playback block 18 is beaten, this hammer playback block 18 is connected with the insurance institution of gun barrel, is provided on hammer playback block 18 The curved surface 19 to match with the outer wall of a protruding portion 14 in hammer 6, the curved surface 19 can drive hammer 6 to rotate.

The course of work of the electric nail gun of the utility model embodiment is as follows：When needing using nail-shooting gun nail nail, press Dynamic switch 12, control motor 2 work, and motor 2 is rotated by the gear driven gear ring 3 on its working end, and then drives three ladders Shape button screw rod 4 rotates simultaneously, due to all opening portions 15 in hammer 6 in the initial state all respectively with corresponding trapezoid buckle It is threadedly coupled between screw rod 4, therefore under the action of three trapezoid buckle screw rods 4 of synchronous rotation, hammer 6 can be along sliding rail 17 The movement in shell 1, the direction of motion are far from the direction of gun barrel 8, and in the process, compression spring 5 is compressed；In this process In, sliding rail 17 is contacted with the outer wall of a protruding portion 14 always, is sliding friction between sliding rail 17 and protruding portion 14；This sliding rail 17 can ensure that hammer 6 will not rotate during movement along the central axes of itself, allow each opening portion 15 can be with Stable connection is formed between trapezoid buckle screw rod 4；

When hammer 6 moves to the end of trapezoid buckle screw rod 4, the separation round platform 16 of opening portion 15 and trapezoid buckle screw rod 4 Contact, since the side of separation round platform 6 carries certain angle, and the relatively small one end of round platform diameter is towards hammer 6 direction, therefore when hammer 6 moves, opening portion 15 can be in the effect of side of the separation round platform 16 with certain angle Lower to be detached with the threaded portion of trapezoid buckle screw rod 4, in this way under the action of compression spring 5, hammer 6 is quickly moved along sliding rail 17 It is dynamic, finally the nail at gun barrel 8 is got, realizes the purpose of nailing；During 6 returning quickly of hammer, due to impact Hammer 6 has rotated certain angle under the action of detaching round platform 16, therefore protruding portion 14 will not be with sliding rail in this state 17 contacts, in this way during 6 return of hammer, can't collide with sliding rail 17, but directly quickly return to just Beginning position；

When needing to project nail again, operating personnel hold handle 11, by 1 front end of shell withstand on one it is fixed flat On face, shell 1 is integrally pressed, the insurance institution of gun barrel can drive hammer playback block 18 to act together（The insurance institution of gun barrel It is the mechanism just having in traditional nailing gun）, curved surface and some protruding portion 14 in hammer 6 that hammer playbacks on block 18 Contact, during above-mentioned movement, under the action of this curved surface, hammer 6 can rotate certain angle, allow all prominent The opening portion 15 gone out in portion 14 contacts and is threadedly coupled with corresponding trapezoid buckle screw rod 4 again, when motor 2 next time works, Hammer 6 is can be driven to move to the rear of shell 1 again；At the same time, nail clip can also be by the ejection one upwards of nail A gauged distance waits for impact of the rifle needle 7 to the nail positioned at the top；

As the above process works repeatedly, you can realize the continual purpose for launching nail.
