Plate 3, the middle lower surface of locking rod 16 has a V-type face 31；The V-type face 31 can connect with the groove 30 on sheave 19
Touch, when locking rod 16 is being in extreme lower position in the presence of back-moving spring 27, V-type face 31 coordinates with the groove 30, limitation
The rotation of sheave 19；Left Drive bar 17 and right drive link 18 are lifted in the presence of left unblock cam 11 and right unblock cam 14
It when rising, can be lifted locking rod 16, no longer limit sheave 19.
When the left hand sleeve 8 that the left operating shaft 4 of correspondence is inserted using handle and after connect left operating shaft 4, left operating shaft 4 can be with
The operation of operation handle and rotate, when left operating shaft 4 turns an angle, left unblock cam 11 promotes Left Drive bar 17,
Locking rod 16 is lifted, sheave 19 is unlocked, the V on positioning disk 22 is pushed down under the twisting force of torsion spring 21 due to positioning connecting lever 20
Type groove 32, so output shaft 5 will not be rotated freely；It is rotated further left operating shaft 4, the first footpath that left wheel 12 enters on sheave 19
To groove 28, sheave 19 is promoted to rotate, the concomitant rotation of output shaft 5, positioning connecting lever 20 is lifted.It is rotated further left operating shaft 4, left wheel
12 separate with the first radial slot 28 on sheave 19, now because sheave 19 is no longer influenced by the effect of left wheel 12, so no longer
Rotate；Connecting lever 20 is positioned in the presence of torsion spring 21, another V-groove on positioning disk 22 is pushed down, now sheave 19 will not be because of outer
Force-disturbance and freely rotate.
Left operating shaft 4 is rotated further, now sheave 19 will not be rotated, left unblock cam 11 is separated with Left Drive bar 17, is locked
Only bar 16 is resetted in the presence of back-moving spring 27, and sheave 19 is locked, and output shaft 5 is thus fixed.
Left operating shaft 4 is rotated further, when the breach of operation handle and left hand sleeve 8 coincide, handle can be extracted.
Under handle extraction state, left operating shaft will not be rotated freely under the pressuring action of the first ripple pearl screw 25.Simultaneously
Left limit block 23 limits left driving wheel, prevents left driving wheel 10 from surmounting setting corner.
When stirring door guard plate 7, when exposing right hand sleeve 9, right operating shaft 6 is in upstate.Operation handle is inserted into
Right hand sleeve 9, you can rotate right operating shaft 6.Because left operating shaft 4 is identical with the course of work of right operating shaft 6, therefore it is not repeated
Describe the course of work of right operating shaft 6.In the right course of work of operating shaft 6, the second footpath that right roller 15 can enter on sheave 19
To groove 29.
It is specifically by left wheel 12 and sheave 19, the right side because the output angle of output shaft 5 is determined by the precision of Geneva mechanism
The machining accuracy and installation accuracy of roller 15 and sheave 19 determine that output angle is not by operation handle, left hand sleeve 8 and right handles
The influence of 9 precision is covered, thus improves the precision of whole mechanism.
During left operating shaft 4 or right operating shaft 6 are persistently rotated, can be continuously finished the unblock of output shaft 5, driving,
Lock again, it is not necessary to operation bidirectional, it is very easy to use.
