Locating part 9 is positioned at the cavity that surface frame 2 is formed with clamp 104, and locating part 9 includes body 91, extension 92, torsion spring location division 93 and extension 94.The shape of cross section of body 91 is ring-type, is set in the connecting shaft that rocking handle is connected with power transmission shaft II 7.Extension 92 is connected with body 91 and is positioned at the top of bayonet socket 22, is not the surface of bayonet socket 22 above bayonet socket 22 herein, only refers only to extension 92 and there is difference in height with bayonet socket 22.Torsion spring 8 is set in one end on body 91 and is connected with torsion spring location division 93, and the other end offsets with surface frame 2.When extension 92 does not extends into bayonet socket 22, torsion spring 8 is in deformed state, such design makes torsion spring 8 give extension 92 1 downforce, it is made to withstand on slide plate 19 upper surface, when slide plate 19 motion drives bayonet socket 22 to move to extension 92 place plane, torsion spring 8 recovers deformation, and extension 92 enters bayonet socket 22 and slide plate 19 is locked.Extension 94 is connected with body 91 lower right of the center of rotation being positioned at body, extension 94 is in bending, and extension 94 end be shaped as major arc, extension 94 end has contact point I 95 and contact point II 96, the position of contact point I 95 is higher than the position of contact point II 96, and the position of contact point II 96 is higher than the position in the major arc center of circle.
When breaker body needs to advance, (namely power transmission shaft II 7 rotates clockwise, slide plate 19 is promoted to make extension 92 and bayonet socket 22 form clamping, when during power transmission shaft II 7 constantly rotates, breaker body can arrive correct position, now lobe I 151 acts on and makes extension 94 offset downward on contact point I 95, extension 92 leaves bayonet socket 22 and unlocks, and clutch button I 4 and clutch button II 5 are in released state.
When breaker body needs rollback (namely power transmission shaft II 7 rotates counterclockwise), slide plate 19 is promoted to make extension 92 and bayonet socket 22 form clamping, when during power transmission shaft II 7 constantly rotates, breaker body can arrive correct position, now lobe I 151 is squeezed on contact point II 96 generation power F, this power F can be analyzed to power F1 towards body center of rotation and power F2 promoting extension 94 to offset downward, under the effect of power F2, extension 92 leaves bayonet socket 22 and unlocks, and clutch button I 4 and clutch button II 5 are in released state.
Being in transmission connection between rotating shaft 15 and planker 3 belongs to routine techniques, use rotating shaft 15 surface axially on offer the sliding tray of distortion, sliding part it is fixed with on base, sliding part part is close to sliding tray, owing to planker 3 is moved with power transmission shaft II 7 rotation, sliding part is close to sliding tray motion and rotating shaft 15 is rotated.When power transmission shaft II 7 rotates clockwise, rotating shaft 15 is for rotating counterclockwise；When power transmission shaft II 7 rotates counterclockwise, rotating shaft 15 is for rotating clockwise.Position relationship between quantity and the lobe I 151 of the lobe I 151 in rotating shaft 15 is arranged (operating position refers to testing position, link position, separation point position the most herein) according to the quantity of the operating position of chopper, and the tip position of lobe I 151 is arc.
Operation principle is as follows: when needs promotion breaker body motion, and artificial promotion slide plate 19 makes clutch buckle I 4 and buckles II 5 clampings formation transmissions with clutch, and extension 92 enters bayonet socket 22 under the effect of torsion spring 8 and locks slide plate simultaneously.Persistently shake rocking handle, when breaker body reaches corresponding operating position, owing to rotating of rotating shaft 15 drives corresponding lobe I 151 to rotate, lobe I 151 acts on extension 94 and makes body 91 rotarily drive extension 92 to leave bayonet socket 22, the locking of slide plate 19 is released from, under the effect of spring I 10 and spring II 11, clutch button I 4 and clutch button II 5 produce mobile and both separate the drive connection released between the two, when shaking rocking handle the most again, power transmission shaft II 7 is in idle running power transmission shaft I 6 will not be driven to rotate.
Said mechanism is used to promote slide plate 19, there is not fastening state in latch I and latch II, the situation that the end face of the such as end face of latch I and latch II offsets, owing to clutch button I 4 stress makes spring II 11 crimp, owing to latch I will not rotate, now rotating drive shaft II 7 makes latch II reach anastomotic site, and spring II 11 recovers deformation latch I and completes clamping with latch II；Therefore, when promoting slide plate 19, clutch button I 4 and clutch button II 5 can be made to complete clamping.
