2.4 are overlapped, and limitation nail housing-case 11 is rotated around shell 2.
Schematic diagram is set as Fig. 7 stirs assembling structure for nail case.It is the function of moving nail certainly of realizing continuous nail feeding machanism that it, which is acted on,.Cone
Gear I 5 and bevel gear II 13 are installed on T-shaped pedestal 6 by transmission shaft 7 and horizontal axis 14, realize the engagement of two bevel gears, then by
The fixation of T-shaped pedestal 6 and shell 2, and realize the position restriction to two gears；Bevel gear II 13 is equipped with and stirs platform 12.1, dials
Dynamic platform 13.1 passes through the poke hole 2.1 of shell 2, is just spaced and suits between nail frame platform 10.1 on horizontal position, when cone tooth
It (turns right) when half-turn before taking turns I 5 turns, stirs platform 13.1 and turn upwards without work, after I 5 turns of bevel gear when half-turn (to the left
Turn), stir platform 13.1 will stir nail case 10 rotate, make it is next deposit nail slot 10.4 position alignment nail housing-case 11 ejector pin hole III
11.2.To achieve the effect that move nail certainly.
If Fig. 9 is pushing device structural schematic diagram.It is to realize automatic nail feeding that it, which is acted on,.Transmission shaft 7 is installed on T-shaped pedestal 6
In pedestal 15, its upper end is equipped with bevel gear I 5, and lower end is equipped with 75 ° of motion angle for actuating travel of cam 16(cam, far angle of repose
30 °, 75 ° of motion angle for return travel, 180 ° of near angle of repose), when bevel gear I 5 rotates, band moving cam 16 is rotated, on driven push rod 17
Roller bearing 17.1 suit with cam groove 16.1, the sliding eye at I 18 middle part of the other end of driven push rod 17 and elevating lever
18.1 are connected, and when sliding causes 18.1 upper end of sliding eye, elevating lever I 18 is in minimum state, under sliding eye 18.1
When end, elevating lever I 18 are raised to highest；The lower end of elevating lever I 18 is connected with the hinge base 2.3 on shell 2, realizes around hinge
The rotation of pedestal 2.3, in the upper end of elevating lever I, by pivot pin 17 and II 20 hinge of elevating lever, the upper end of elevating lever II 20 with push away
The hinge seat 21.1 of rivet nut 21 is connected, and ejector pin body 21 is placed in the ejector pin slot 2.5 of shell 2.When bevel gear I 5 rotates (to the right)
At 180 °, synchronous also rotate by cam 16, and nail is sent in the realization of ejector pin body 21, and returns to original position.At 0 ° ~ 75 °,
Elevating lever I 18, elevating lever II 20 and ejector pin body 21 are in propradation；When going to 75 °, ejector pin body 21 rises to maximum position；
At 75 ° ~ 105 °, ejector pin body 21 is remained stationary；When going to 105 °, ejector pin body 21 is begun to decline；105 ° ~ 180 ° elevating levers I 18 rise
Drop bar II 20 and ejector pin body 21 are in decline state；When going to 180 °, pushing meanss are restored as former state.After bevel gear I 5 rotates
It (turns left) when half-turn, nail case striking gear is started to work, and cam 16 is near angle of repose at this time, and pushing device is without work
Make.
