Then, when the user no longer exerts any force to pull the gripping portion 521 and the sliding frame 600, the restoring force of the elastic restoring member 701 drives the gripping portion 521 and the sliding frame 600 in the opposite direction (eg, the movement direction D1), so that the hook portion is The hook body 811 of the 802 is moved to the end surface 453 of the second plate member 450 ( FIG. 7A ), and the hook body 811 of the hook portion 802 can be fastened to the end surface 453 of the second plate member 450 ( FIG. 7B ) , so that the tenon mechanism 302 is temporarily unlocked.

It should be understood that the clip 514 has a hook shape with a beveled edge 518 , and the opening 430 has an inner edge 431 . Therefore, when the sliding frame 600 is pulled toward the moving direction D2, the inner edge of the opening 430 pushes the beveled edge 518 of the clip 514, so that the protruding portion 613 can move in more smoothly and expand the gap between the elongated sheet body 510 and the frame 400. gap between.

In addition, in this embodiment, the hook portion 802 of FIG. 6A can also be replaced with the hook portion 801 of FIG. 5A , as long as the free end of the elastic arm of the second piece of the bracket extends toward the ring-shaped handle , so that the hook can be fastened to the end surface 453 to store the restoring force of the elastic reset element 701 .

FIG. 8 is a perspective view of the tenon mechanism 303 according to the fourth embodiment of the present invention. As shown in FIG. 8 , the tenon mechanism 303 of FIG. 8 is substantially the same as the tenon mechanism 302 of FIG. 6A , the difference is that the gripping portion 523 of the tenon mechanism 303 is pivoted on the bracket 610 , not fixedly connected to the bracket 610 on.

Specifically, the chassis 200 has a blocking surface 210 facing the holding portion 523 . The holding portion 523 includes a body 550 , a pivot shaft 553 and a handle 555 . The handle 555 is connected to one side of the body 550 . The body 550 is pivotally connected to the end of the bracket 610 away from the fixing portion 515 through the pivot shaft 553 , so that the body 550 can rotate relative to the sliding frame 600 around the axis of the pivot shaft 553 . More specifically, the body 550 includes an abutting portion 551 and an inclined portion 552 . The abutting portion 551 is adjacent to the inclined portion 552 and is disposed opposite to the handle 555 . The minimum linear distance 551L from the pivot shaft 553 to the abutting portion 551 is greater than the minimum linear distance 552L from the pivot shaft 553 to the inclined portion 552 . In other words, the pivot shaft 553 is not on the centroid of the body 550 .

FIG. 9A is an operation diagram of the tenon mechanism 303 of FIG. 8 in the buckled state. FIG. 9B is an operation diagram of the tenon mechanism 303 of FIG. 8 in a permanent unlocked state. FIG. 9C is an operation diagram of the tenon mechanism 303 of FIG. 9B no longer being fastened by the fastening portion. As shown in FIG. 9A , when the user pulls the grip portion 523 and the sliding frame 600 to the left (eg, the movement direction D2 ), the hook portion 802 is fastened to the fastening portion (ie, the end surface 453 of the frame 400 ), and the The tenon mechanism 303 is in an unlocked state (FIG. 9A). Next, the user rotates the holding portion 523 again, so that the abutting portion 551 of the holding portion 523 directly abuts against the blocking surface 210 of the rack 100 ( FIG. 9B ). Therefore, the movement of the sliding frame 600 is respectively restricted by the blocking surface 210 and the buckle portion (ie, the end face 453 of the frame 400 ), and the elastic restoring member 700 is continuously in a deformed state and is prevented from releasing the restoring force, so the sliding frame 600 cannot be moved. The elastic return member 700 is pulled back to its original position.

In this way, even if the hook body 811 is pushed back into the accommodating space 420 by the triggering portion 150 , the blocking of the sliding frame 600 by the end surface 453 is released ( FIG. 9C ), however, the blocking surface 210 stops the gripping portion 523 Therefore, the sliding frame 600 cannot be pulled back to the original position by the elastic reset member 700, so that the tenon mechanism 303 of this embodiment can be permanently unlocked, and the sliding frame 600 cannot be blocked by the buckle portion (ie, the end surface 453 of the frame 400). The stopper is released (Fig. 9B).

Since the abutting portion 551 of the holding portion 523 is farther away from the pivot shaft 553 than the inclined portion 552 , when the holding portion 523 rotates relative to the sliding frame 600 in the rotation direction C1 , the blocking surface 210 of the rack 100 can directly abut against the holding portion 552 . On the other hand, when the holding portion 523 rotates relative to the sliding frame 600 in the rotation direction C2, the abutting portion 551 of the rack 100 does not directly abut against the blocking surface 210 of the rack 100, and the The blocking surfaces 210 of the rack 100 maintain the spacing.

In this way, when the holding portion 523 is rotated so that the abutting portion 551 of the rack 100 faces the blocking surface 210 of the rack 100 , since the abutting portion 551 of the rack 100 cannot directly stop the blocking surface 210 , once the sliding frame The sliding frame 600 can be pulled back to the original position by the restoring force of the elastic restoring member 700 when the 600 is no longer blocked by the buckle portion (ie, the end surface 453 of the frame 400 ).

Finally, the above disclosed embodiments are not intended to limit the present invention.
