[0023] In the present embodiment, the damping seat 5 comprises a seat body 51 with two open ends, the two open ends are defined as an inlet and an outlet, the seat body 51 is in a plate-shaped structure; one end of the seat body 51 is connected to the right movable plate 3 by a fastener, so that the seat body 51 moves with the right movable plate 3; a torsion spring is mounted on the left movable plate 4 by a fastener; the inlet of the seat body 51 faces the torsion spring; two torsion spring arms 6 of the torsion spring are inserted simultaneously from the inlet and exit from the outlet; since the two torsion spring arms 6 are in an opened state, when the two torsion spring arms 6 exit from the outlet, the two torsion spring arms exit closely against both sides of the outlet, so that the two torsion spring arms 6 are respectively abutted against both sides of the outlet; when the right handle 1 and the left handle 2 rotate with each other, the right movable plate 3 and the left movable plate 4 are also opened and closed therewith; in an initial state, the left movable plate 4 and the right movable plate 3 are tightly fitted with each other, at this point, the damping seat 5 is located near a bottom end of the torsion spring arm 6, and the torsion spring is in a natural state; when the left movable plate 4 and the right movable plate 3 are separated from each other, the damping seat 5 and the torsion spring slide in a reverse direction to separate, at this point, the damping seat 5 slides along the torsion spring arm 6, and the damping seat 5 slides from the bottom end of the torsion spring arm 6 to an opened top end, so that the two torsion spring arms 6 are gradually tightened by the damping seat 5, thereby forming a damping motion; when the wire stripping action is completed, as the left movable plate 4 and the right movable plate 3 approach each other, the damping seat 5 and the torsion spring arm 6 also slide relative to each other, at this point, the damping seat 5 slides from the opened top end of the torsion spring to the bottom end, and the torsion spring returns from the tightened state to the opened state; and finally, a restoring force of the torsion spring drives the damping seat 5 to a bottom portion of the torsion spring arm 6, and the left movable plate 4 and the right movable plate 3 return to the initial state of tight fit.

[0024] In addition, both sides of the seat body 51 are bent towards the direction where the torsion spring arm 6 is located to form guide side plates 52, and the guide side plates 52 can not only protect the torsion spring, but also guide the torsion spring arm 6 in the relative sliding between the seat body 51 and the torsion spring arm 6, so as to make the sliding more stable.

[0025] It should be noted that the torsion spring arms 6 can be formed into a multi-section structure, that is, each torsion spring arm 6 presents a multi-section structure according to different opening angles, so that when the damping seat 5 slides along the two torsion spring arms 6 and tightens the two torsion spring arms 6, different damping sense can be achieved.
