The elongated slot 33 of the end portion 31 . Each slot 33 extends axially and communicates with the mounting hole 32 .

The pull rods 4 are slidably inserted axially into the installation holes 32 from the two ends 31 respectively, each pull rod 4 is a hollow long tube, and has an indented section 41 capable of retracting into the edge strip 3 , a protruding section 42 constantly protruding from the edge strip 3 and a collapsed portion 46 disposed on the protruding section 42 . Each pull rod 4 also has a post 44 mounted on the indented section 41 and protruding outwards into the elongated slot 33 , a sleeve section 43 located on the side of the indented section 41 away from the extended section 42 , A connecting piece 45 installed on one side of the retracting section 41 close to the sleeve section 43 .

The protruding section 42 has a rod end 421 remote from the retracting section 41 . In this embodiment, the socket sections 43 of the two tie rods 4 are inwardly and externally connected to each other, that is to say, the diameter of one of the socket sections 43 of the said socket sections 43 is smaller than that of the other socket sections 43. The diameter of the sleeve section 43, of course, can also omit the setting of the sleeve section 43 in practice. Each boss 44 is slidably located in the long slot 33. In assembly, the indented section 41 is inserted into the mounting hole 32 of the edge strip 3, and then the boss 44 is passed through the long slot 33. The sockets on the indented section 41 are inserted into the indented section 41 , so that each tie rod 4 can move left and right relative to the edge bar 3 .

The crush portion 46 of each tie rod 4 has at least one notch 461 corresponding to the radially inward recess from the outer peripheral surface of the protruding section 42 . Each notch 461 can be V-shaped or U-shaped, so the shape and quantity of the notches 461 are not limited to this embodiment. And by the setting of the notch 461, the tie rod 4 is easier to collapse, deform or break at the position of the collapsed portion 46 than other parts, at least relative to the indented section 41 of the pull rod 4, and the crushed portion 46 is the 4 The part where the shape changes rapidly, so when the external force is applied, due to the stress concentration, the collapsed part 46 will collapse and deform or break first, reducing the damage probability of other parts of the tie rod 4, especially the retracted section 41.

It should be noted that the form of the collapsed portion is not limited to a notch, and may also be formed by at least one protrusion protruding radially outward from the outer peripheral surface of the protruding section, or other feasible forms. It only needs to make the crush portion 46 and the extension section 42 bend and connect, so as to concentrate the stress.

The elastic member 5 is a tension spring, which is located in the installation hole 32 of the side strip 3, and is connected to the indented section 41 of the pull rod 4, and has two springs respectively connected to the connecting parts 45 of the pull rod 4 Foot 51.
