Condition.
S1. point switch connection operation:
The initial position that push rod 24 is arranged is to execute convex block 241 to be in the top executed in gap 27 towards the second convex block 222
The position when side of portion side, push rod 24 at this time is contraction state;Wherein, the first rotating cylinder 21, the second rotating cylinder 22 and shell 1
Axis it is consistent;Contact switch is connected on the bottom position of shell 1;
It is shape since the first convex block 212 and the second convex block 222 are formed by between execution gap 27 and the axis of shell 1
Angle at an acute angle, therefore knob 11 is screwed counterclockwise, during so that the first rotating cylinder 21 and the second rotating cylinder 22 is rotated counterclockwise, hold
Row convex block 241 will be moved along execution gap 27 backwards to the side of 222 top-side of the second convex block;Again due to one end of push rod 24
It is inserted into locating slot 127, therefore so that push rod 24 is merely able to move along the axis direction of shell 1;
To sum up, the mobile route in conjunction with execution convex block 241 in execution gap 27 and push rod 24 are in locating slot 127
Execution route will be it is found that rotating counterclockwise with the first rotating cylinder 21 and the second rotating cylinder 22, push rod 24 will be moved towards the bottom of shell 1
Dynamic, after knob 11, which rotates counterclockwise, reaches designated position, executing convex block 241 will be from gap 27 be executed towards the second convex block 222
The side at top is moved to and executes side of the gap 27 towards 212 bottom of the first convex block, to realize push rod 24 by contraction state
Switch to the effect of stretching state so that the bottom of push rod 24 can be contacted with the hard contact of contact switch, and make contact switch
It connects;
It will be by during the first rotating cylinder 21 rotates, between the locking convex block 311 of locating convex block 214 and locking sleeve 31
It is aligned condition that occlusive state before is gradually mobile, at this point, locking sleeve 31 will backwards to the movement of the first circular protrusion 213 and
Compressed spring 32 makes spring 32 have elastic potential energy;
When the first rotating cylinder 21 rotates again, locating convex block 214 and locking convex block 311 between will by aligned condition again by
Gradually restore to occlusive state, and during restoring to occlusive state, spring 32 makes locking sleeve 31 by elastic potential energy is discharged
It is moved towards the first circular protrusion 213, locking convex block 311 is made to be engaged again with locating convex block 214;Wherein, spring 32 is entire
It is compressive state in the process, locking convex block 311 is enable closely to be pressed together on locating convex block 214, makes the first sleeve and lock
Fixed cylinder 31 is fixed to each other, and receives the situation that slight external force can push push rod 24 to move to avoid knob 11, ensure that half
The safety and stability of 11 safety switch of automatic knob.
S2 contact switch opening operations:
The initial position that push rod 24 is arranged is to execute convex block 241 to be in the bottom executed in gap 27 towards the first convex block 212
The position when side of portion side, push rod 24 at this time is stretching state;Knob 11 is screwed clockwise, makes the first rotating cylinder 21 and
During two rotating cylinders 22 rotate clockwise, executing convex block 241 will be along executing gap 27 towards 222 top-side of the second convex block
It moves side;Again since one end of push rod 24 is inserted into locating slot 127, so that push rod 24 is merely able to along shell 1
Axis direction moves;
To sum up, the mobile route in conjunction with execution convex block 241 in execution gap 27 and push rod 24 are in locating slot 127
Execution route will be it is found that rotating clockwise with the first rotating cylinder 21 and the second rotating cylinder 22, push rod 24 will be moved backwards to the bottom of shell 1
Dynamic, after knob 11, which rotates clockwise, reaches designated position, executing convex block 241 will be from gap 27 be executed towards the first convex block 212
The side of bottom is moved to the side for executing gap 27 towards 222 top of the second convex block, to realize push rod 24 by stretching state
Switch to the effect of contraction state so that the bottom of push rod 24 and the hard contact of contact switch are detached from, and contact switch is made to disconnect;
It will be by during the first rotating cylinder 21 rotates, between the locking convex block 311 of locating convex block 214 and locking sleeve 31
It is aligned condition that occlusive state before is gradually mobile, at this point, locking sleeve 31 will backwards to the movement of the first circular protrusion 213 and
Compressed spring 32 makes spring 32 have elastic potential energy;
