Existing screw is all whether artificial judgment tightens in assembling process, and this, which is resulted in, may assemble pine or mistake
Tightly, cause to damage.
The content of the invention
In order to solve the above technical problems, the invention provides a kind of torque take-up screw assemblies, torsion during assembling can control
Power, screw, which turns clockwise, locks the ratchet skidding when reaching certain moment of torsion, and screw does not continue to receive bigger torsion to lock
Tightly, driving pawl counterclockwise, screw release, and prevent assembling process pine or tension excessively from causing to damage.
The technical solution adopted for the present invention to solve the technical problems is：A kind of torque take-up screw assemblies, it includes handle
Hand, ratchet, jump ring and screw；The centre position of the side of the ratchet is provided with the first tread；The upside of first tread is small
Diameter end, its top surface are provided with jack；The downside of first tread is larger diameter end, and its bottom surface is provided with ratchet slot；The screw head
The centre position of the side of socket cap is provided with the second tread；The upside of second tread is larger diameter end, the excircle of its top surface
On be provided with neck；The jump ring includes C-shaped body, and one end of C-shaped body upwardly extends and to form ratchet, the other end extends downwardly
Form card column；The handle is the hollow cylinder that both ends are closed up, and the bottom surface of ratchet contacts with the top surface of screw, and handle sleeve is in ratchet
And screw, and by the first tread and the second tread by ratchet and screw riveted；The jump ring is arranged in ratchet, and its ratchet is inserted
In the ratchet slot of ratchet, card column is inserted in the neck of screw.
The ratchet rotates freely with screw in handle.
The bottom of the screw is provided with threaded portion.
During tight condition, ratchet is rotated clockwise, the ratchet of jump ring is stuck in the ratchet slot of ratchet, drives screw to be twisted
Tight action.
When being screwed to the torsion upper limit, the ratchet of jump ring skids in the ratchet slot of ratchet, and screw stops tightening action.
When unscrewing state, ratchet is rotated counterclockwise, the ratchet of jump ring is stuck in the ratchet slot of ratchet, drives screw to be twisted
Loosen and make.
Beneficial effects of the present invention：A kind of torque take-up screw assemblies of the present invention, it can control torsion during assembling, screw
The locking ratchet when reaching certain moment of torsion that turns clockwise skids, and screw does not continue to receive bigger torsion to lock, the inverse time
Pin driving pawl, screw release, and prevent assembling process pine or tension excessively from causing to damage.
