Back-out screw rod embodiment:
By the rotation direction of non-cap screw rod be dextrorotation namely clockwise for, when need to back-out screw rod from threaded hole come
When:
Positive six side of 306 clamping of regular hexagon boss in the second wrench portion 2 under reset condition, in third wrench portion 3
In shape hole 205；
When limited block 5 is opened (plucking out out of limited block mounting groove 303) and is locked by Spring lock catch 4, bullet at this time
Spring 10 is original state, and third wrench portion 3 can be moved up and down along the inner hole in the second wrench portion 2, at this point, by third spanner
The second threaded hole 302 in portion 3 is directed at screw rod to be back-outed, and rotates clockwise spanner handle 6 and is screwed into, at this point, due to pawl 8
It exerts a force to the first wrench portion 1, the first wrench portion 1 can follow handle 6 to rotate, and continue to rotate handle 6, third wrench portion 3 enters
In second wrench portion 2；Continue to be screwed into screw rod, until the first threaded hole 104 in the first wrench portion 1 is also fully screwed into screw rod, it
Another mistake hour hands swing handle 6 afterwards, 8 rotation direction reversed of pawl, no longer exerts a force to the first wrench portion 1 at this time, and the second wrench portion 2
It is rotated counterclockwise relative to the first wrench portion 1, internal screw thread that this rotation direction opens up on the side wall with annular groove 102, second
The rotation direction of the first external screw thread 201 in wrench portion 2 is identical, and the first external screw thread 201 in the second wrench portion 2 is gradually screwed into annular groove
In 102, so that the contact surface of third wrench portion 3 and the first wrench portion 1 occurs to top, simultaneously because having grease lubrication, ring to top surface
Also have lubrication between shape slot 102 and the first external screw thread 201, compared to the frictional force to top surface cause the first wrench portion 1 rotate and
Speech, the first external screw thread 201, which is screwed into annular groove 102, will be easy many, therefore can become better and better to top effect, in the case where acting on top,
Axial compression power between third wrench portion 3 and the second wrench portion 2 is transmitted to the first threaded hole 104, the second threaded hole 302 and spiral shell
On the contact surface of bar screw thread, so that entire spanner is increased with respect to the frictional force that screw rod rotates, until opposite turn cannot occur
It is dynamic, as long as continuing to rotate counterclockwise spanner at this time, so that it may back-out screw rod from matched screw thread and come.
It is screwed into screw rod embodiment:
The prior step of screw rod is screwed into back-outing and being, i.e. first another mistake hour hands rotating spanner handle 6 clockwise, waited
Occur to top effect and then turn clockwise, 8 rotation direction of pawl commutates at this time, applies clockwise to the first wrench portion 1 again
Rotating torque, due to top effect have already appeared, as long as the first wrench portion 1, which is rotated clockwise, is screwed into target for screw rod
Threaded hole.
Spanner is screwed out into embodiment from screw rod after having used:
Spanner and screw rod separately need to release the first wrench portion 1 with third wrench portion 3 to top, when releasing to top, only need
The Spring lock catch 4 is opened, so that the limited block 5 is closed (limited block 5 is loaded in limited block mounting groove 303), i.e.,
Complete release of the Spring lock catch 4 to limited block 5；
Then the handle 6 for rotating counterclockwise spanner, since limited block 5 no longer works at this time, handle 6 can only be driven
The rotation of second wrench portion 2, third wrench portion 3 not followed by rotation in situ motionless, with the rotation of the second wrench portion 2, the
One external screw thread 201 is slowly screwed into annular groove 102, and because the length of the first external screw thread 201 is longer than annular groove 102, is screwed to
After bottom, the second wrench portion 2 can start that the first wrench portion 1 is driven to rotate counterclockwise, and release immediately to top.
Continue to rotate counterclockwise handle 6, the contact surface of the first wrench portion 1 and third wrench portion 3 starts to separate, until third
The bulge-structure 306 of wrench portion 3 is fallen into the hexagonal hole 205 of the second wrench portion 2, at this point, due to bulge-structure 306 and
It is the cooperation of regular hexagon cylinder between hexagonal hole 205, the second wrench portion 2 starts that third wrench portion 3 is driven to rotate counterclockwise,
Until entire spanner screws out completely from screw rod.
