When block 12 just can ensure that locking hand goes to specified location 16 with locking the distance between shifting block 11 locking act on will not too tightly or
Not tight.Certain machine was used after certain time, it is also possible to the shape of head not tight is caused because of the prolonged vibrations of machine
State, at this moment can realize that regulation regulation shifting block, with locking the distance between shifting block, makes dress by adjusting the second screw and nut
The locking effect put is more preferable.
The present invention operation principle be：
The operation principle of detent mechanism is to fall when angle positions the resilient key 8 on knob 7 in the resilient key locating surface of workbench 1
When 9, latch 72 does not occur simultaneously with the angle positioning hole on angle location-plate 4, and now head section can arbitrarily beat, rotational angle
Knob 7 is positioned, resilient key 8 above it is deviateed workbench resilient key locating surface 9, in the presence of stage clip, latch 72 is to branch
Arm direction is acted, and in the angle positioning hole of the insertion angle location-plate of latch 72, head is not rotated further by, but now head is not exclusively locked
It is fixed, there is certain interval between latch 72 and positioning hole, and it is only also unreliable by latch and positioning hole locking.
The similar lever principle of operation principle of retaining mechanism, stirs both sides and locks hand 16, make the surface of locking roller 24
When being contacted with the locking positioning face 32 on support arm 3, now the distal shaft end of the lock cam 14 on lock shaft 13 and locking shifting block 11
Rear-face contact, locking the stress of shifting block 11 after, this be lever principle in the point of application, its bottom also just gradually withstands on the first connection
On pin 18, and it is final by maximum, force, now turn into the distal shaft end on the fulcrum in lever principle, lock cam 14 and lock herein
After the rear-face contact of tight shifting block 11, regulation shifting block 12 drives the second connecting pin 19 to be acted in the cunning elongated slot 111 of locking shifting block 11
To the most side end of sliding elongated slot, the locking roller 24 on the second connecting pin 19 is acted also with to the direction of support arm 3, and this is stress point.
So that the locking positioning face 32 on the surface and support arm of locking roller 24 is tightly sticked together, it is no longer able to turn head, really
Protect head fixed.
When rotational lock hand is 16, locking limited block 22 is rotated with the rotation of lock shaft 13, until locking spacing
When the plane positioning face 221 of block is in contact with support arm, locking hand is no longer able to turn 16, and now head is locked.
After the contact surface of locking shifting block 11 is gradually left at the distal shaft end of lock cam 14, in the effect of spring bearer plate 15
Under, regulation shifting block 12 is gradually acted under the drive of the second connecting pin 19 to the opposite direction of support arm 3, then the table of locking roller
Face is contacted with the locking positioning face 32 of support arm 3 and gradually decreased, until transfering to, head can be rotated again.
Finally illustrate, preferred embodiment above is merely illustrative of the technical solution of the present invention and unrestricted, although logical
Cross above preferred embodiment the present invention is described in detail, it is to be understood by those skilled in the art that can be
Various changes are made to it in form and in details, without departing from claims of the present invention limited range.
