Accordingly, the first link plate 310 has a substantially '' shape.

As shown in FIG. 2, the second link plate 320 is formed to have a structure corresponding to the first link plate 310, and the upper portion of the first link plate 310 is formed on the second link plate 320. A second shaft 324 is provided to be slidably coupled to the first guide hole 314, and is spaced apart from the second shaft 324 by a predetermined distance to guide the sliding entrance of the first shaft 312. The guide hole 322 is provided below the second link plate 320. Like the first link plate 310, the second link plate 320 forms an operating space S between the second shaft 324 and the second guide hole 322. In addition, a second pin hole 324a is formed in the second shaft 324 as in the first shaft 312, and is coupled to the second shaft pin 120 of the fixed frame 100, and in the second pin hole 324a. An incision 324b is formed in the second shaft 324 so that the second shaft pin 120 is coupled to the second shaft 324.

The first link plate 310 and the second link plate 320 of the corresponding structure are connected to the plurality of tension springs 330, and circular hook rings 332 are formed at both ends of the tension springs 330. do.

A plurality of ring coupling grooves 318 and 328 are formed in both link plates 310 and 320 so that the hook ring 332 of the tension spring 330 is coupled to each other. On the upper inner circumferential surface of each of the ring coupling grooves 318 and 328 formed in a cylindrical shape, a pair of separation prevention rims 319 and 329 are formed to form a hook ring 332 coupled to the ring coupling grooves 318 and 328. This prevents the departure. 2 and 4, the upper edges of the departure preventing rims 319 and 329 are hooks that are elastically coupled to the ring coupling grooves 318 and 328 formed of inclined guide surfaces 319a and 329a. Guide the smooth entry of the ring 332. Here, the inner diameter of the ring coupling grooves 318 and 328 is similar to or slightly larger than the outer diameter of the hook ring 332, and is elastically deformed by a constant external force and coupled to the ring coupling grooves 318 and 328.

As shown in an enlarged view at the top of FIG. 2, flow preventing bosses 317 and 327 having an appropriate outer diameter are formed at the center of each ring coupling groove 318 and 328 to fit the inner diameter of the hook ring 332. In addition, the flow preventing bosses 317 and 327 are formed in a form in which the central part is pierced and partially symmetrical. Accordingly, the hook ring 332 is fitted into the outer diameter of the flow preventing bosses 317 and 327 to interrupt the flow in the direction in which the tensile force acts.

In addition, as shown in FIG. 2, both link plates 310 and 320 have a plurality of shoulders 315 and 325 formed to protrude between the ring coupling grooves 318 and 328, such shoulders 315.
