Specific embodiment
The present invention is described in further details below.Referring to Fig. 1~4.
A kind of adjustable rotary motion trigger device of trigger angle, it is characterized in that: the motion triggers device includes upper
Cam 1, lower cam 2, rotary shaft 3, needle roller 4, pusher bar support 5, push rod 6, screw 7, gasket 8, rubber pad 9, microswitch 10 are micro-
Dynamic switch pedestal 11.
Threaded hole is provided on 3 boss of rotary shaft, overhead cam 1 is fixed on 3 boss of rotary shaft by two screws 7, and two
Lower cam 2 and overhead cam 1 are compressed and are fixed on 3 boss of rotary shaft by screw 7, and overhead cam 1 is circular ring shape, and edge is provided with fan
V notch v, lower cam 2 are also circular ring shape, are provided with sector notch identical with overhead cam 1,1 emargintion of overhead cam left side thereon
Scarf forming V-shape slot on the right side of inclined-plane and 2 emargintion of lower cam, 3 lower end of rotary shaft are placed in joint outer part housing bore, can
It rotates in a circumferential direction；In the V-shaped groove that right side protrusion is placed in overhead cam 1 and lower cam 2 is formed of push rod 6, it is tabular on the left of push rod 6, puts down
It is provided with U-lag on the downside of plate, pusher bar support 5 is fixed on the shell of joint outer part by two screws 7, and pusher bar support 5 is plate
Structure, upside are equipped with boss, set through-hole on boss and connect with push rod 6, set on boss on 6 left side U-lag corresponding position of push rod
There is through-hole to connect with needle roller 4.Needle roller 4 is placed in 6 left side U-lag of push rod, and microswitch pedestal 11 is fixed on outer by two screws 7
