First Claim
1. A slider with a reboundable pull-tab, comprising:
- A slider base, the pull-tab, a connecting shaft and a spring;
the slider base comprising an upper blade, a lower blade, and a connecting pin connecting the upper blade and the lower blade;
wherein,upper blade lateral sides are formed on two sides of the upper blade, each of the upper blade lateral sides has two through-holes, comprising a first through-hole and a second through-hole, for mounting the connecting shaft;
the upper blade further comprises a square-shaped notch for disposing the pull-tab;
the square-shaped notch comprises an arc-shaped notch, an anterior-end of the arc-shaped notch connects to sidewalls of the square-shaped notch and a posterior-end of the arc-shaped notch connects to a bottom surface of the square-shaped notch;
a locking through-hole is disposed at a joint portion between the square-shaped notch and the arc-shaped notch;
the locking through-hole separates the arc-shaped notch into a first arc-shaped notch on a side of the first through-hole and a second arc-shaped notch on a side of the second through-hole;
an anterior-end platform is disposed at a joint portion between an anterior-end of the first arc-shaped notch and the sidewalls of the square-shaped notch, and a posterior-end of the first arc-shaped notch connects to the bottom surface by a locking vertical plane;
a posterior-end of the second arc-shaped notch connects to the bottom surface directly and an anterior-end of the second arc-shaped notch connects to the sidewalls of the square-shaped notch;
the anterior-end platform has a lug boss at the second arc-shaped notch;
the pull-tab comprises a pull-tab body, a top-end of the pull-tab body has a spring mounting part and a locking part, wherein the spring mounting part and the locking part are adjacent to each other;
the spring mounting part has a cambered surface and the locking part has a locking cambered surface that is lower than the spring mounting part;
the top-end of the pull-tab body also has a connecting shaft through-hole for assembling the connecting shaft so as to fix the pull-tab to the slider base;
the spring mounting part has a spring mounting hole coaxially provided with the connecting shaft through-hole, and a radius of the spring mounting hole is larger than a radius of the connecting shaft through-hole;
a lateral side of the pull-tab body has a spring fixing hole communicating with the spring mounting hole;
two ends of the spring has a first extending end and a second extending end, wherein the first extending end has a corner;
when the slider is assembled, the spring is fit in the spring mounting hole;
wherein the corner is disposed at a joint portion between the lug boss and the second arc-shaped notch;
the second extending end inserts into the spring fixing hole;
when the slider is assembled, the spring is in a compressed state.

Abstract
The present invention discloses a slider with an reboundable pull-tab, comprising a slider base, a pull-tab, a connecting shaft and spring; the slider base has a connecting shaft through-hole for mounting the connecting shaft, which fixes the pull-tab and spring onto the slider base; one end of the spring inserts into the slider, and the other end inserts into the spring base; when the pull-tab is pulled, the spring will subject to torsional deformation; when the pull-tab is let go, the pull-tab will revert to the normal state under the impetus of the spring, then the slider is automatically locked, thus preventing unexpectedly sliding; There is also a locking part in the pull-tab, so that it is free from not being able to rebound due to over-rotation.
