Specific embodiment
The utility model is described in further detail with specific embodiment with reference to the accompanying drawing, a kind of quick despatch company
Connected components, the component are made of screw assembly and nut assembly, wherein
The screw assembly includes screw 1 and mandril 3, which has through-hole, and the upper end of through-hole is two-stage step hole,
Lower end is stepped hole, and screw 1 is also with the notch 10 of tail portion, and with the head of a nail 4, mandril 3 can be in screw 1 for 3 lower end of mandril
It moves in through-hole and is limited by the stepped hole at both ends；
The nut assembly includes nut 6, spring 7 and snap-gauge 9, which is open-ended cylindrical structure, in
Chamber top has screw thread, and radial through-hole 11 is provided on cavity, and snap-gauge 9 passes through the radial through-hole 11 and can axially move, in advance
The spring 7 of compression is mounted between inner cavity lower end surface and snap-gauge 9, and the snap-gauge 9 is embedded in the notch 10 of screw 1 in connected state
In.
The screw assembly further includes external retaining ring 2.The nut assembly further includes nut supporting plate 5.The nut 6
Bottom end limits spring 7 by blocking film 8.The radial through-hole 11 determines the scope of activities of snap-gauge 9 along axial length.It is described
The screw thread of screw assembly uses double thread form.The screw thread of the nut assembly uses double thread form.
For the utility model during being screwed into, the cross recess of screw 1, the mandril 3 of screw assembly are withstood in operational instrument head
Quickly sink, and then the head of a nail 4 is pushed to sink, the head of a nail 4 pushes the snap-gauge 9 of nut assembly to move downward in sinking watching；At this time
Operational instrument starts to rotate, and under the action of double thread, 1 sharp downward movement of screw, spring 7 is compressed.Screw 1 is screwed into
Behind position, operational instrument is unclamped, the snap-gauge 9 of nut assembly is moved upwards under the action of the spring, is sticked into the notch of 1 tail portion of screw,
So that screw assembly is opposing stationary with nut assembly, so far connector and connected piece complete Quick fastening.
During back-outing, the cross recess of screw 1 is withstood on operational instrument head, and the mandril 3 of screw assembly quickly sinks, into
And the head of a nail 4 is pushed to sink, the head of a nail 4 pushes the snap-gauge 9 of nut assembly to move downward in sinking watching；Operational instrument starts at this time
It reversely rotates, under the action of double thread, 1 fast upward motion of screw, spring 7 extends.After screw 1 exits screw thread, unclamp
Operational instrument, 1 head of screw is unlikely under the action of retaining ring 2 to be fallen from connected piece, and so far connector and connected piece are complete
At fast quick-detach.
