Embodiment
With reference to specific embodiment, the invention will be further described.Following examples are only used for clearly illustrating
Technical scheme, and can not be limited the scope of the invention with this.
Patent of the present invention is further illustrated with reference to the accompanying drawings and examples.
As shown in Figure 1-2, the present invention, which provides a kind of screw rod, has the bolt of elongation function, including canned paragraph 8 and active segment,
The active segment is placed in the cavity inside the canned paragraph 8, and two U-shaped guide rails 6 are arranged with the inwall of canned paragraph 8,
Elastic button 7 is provided with the position of the active segment bottom correspondence U-shaped guide rail 6, the elastic button 7 is by compressing bullet
Spring is fixed on the wall of the active segment side, and the upper end of U-shaped guide rail 6 is provided with positioning hole, and the elastic button 7 is in U-shaped guide rail 6
Move up and down, so that drive active segment to move up and down, and because the restoring force of compression spring causes elastic button 7 to be connected to positioning
In hole, the positioning of active segment and canned paragraph 8 is realized；
The active segment includes screw body 1 and is arranged on the adjusting part of the periphery of screw body 1；The adjusting part is included extremely
Few 2 sector elements 2, the sector element 2 constitutes a circumference and is arranged on the periphery of the screw body 1, and the center of circle exists
The circumference of the center of the screw body 1, i.e. sector element 2 composition is concentric circles with screw body 1；The sector element 2
Inwall be connected by flexible 3 bars with the outer wall of the screw body 1, the outer circumferential walls that sector element is constituted are provided with and nut
The screw thread of matching, during 3 elongation state of expansion link, the active segment external diameter is equal with the external diameter of canned paragraph 8.
By the mutual cooperation of canned paragraph and active segment, length that can be according to actual needs to screw rod is adjusted, from
And meet the fixation of different-thickness；Use for convenience, by the flexible diameter that can adjust active segment of expansion link with
The paper pulp of canned paragraph is equal.
The one end of the expansion link 3 is put in and is fixed on inside screw body 1, and the other end is fixed with sector element 2
It is connected, and puts in the length and the exposed equal length in outer portion of the interior section of screw body 1, during contraction, exposed outer portion
