[0031] Referring to FIGS. 5-6, and FIG. 3, FIG. 5 is a cross section diagram of the connector along line A-A shown in FIG. 4; FIG. 6 is a cross section diagram of the connector along line B-B shown in FIG. 4.

[0032] In the exemplary embodiment, the connecting member 500 includes a sleeve 520 and an inserting element 540. And, the sleeve 520 is fixedly connected with the box fastener 400; the inserting element 540 is fixedly connected with the frame fastener 200; the sleeve 520 is clamped with the inserting element 540, and can rotate relative to the inserting element 540. Preferably, the sleeve 520 is integrated with the box fastener 400; the inserting element 540 is integrated with the frame fastener 200.

[0033] In detail, in the exemplary embodiment, one end of the sleeve 520 is fixedly connected with the box fastener 400, the other end of the sleeve 520 is defined with a receiving cavity (not labelled) for receiving the inserting element 540; an inner

2019100231 04 Mar 2019 surface of the receiving cavity is defined with a plurality of sliding grooves 522, the extending direction of the sliding groove is perpendicular to the axial direction of the sleeve 520, and the sliding grooves 522 are arranged in order along the axial direction of the sleeve 520.

[0034] One end of the inserting element 540 is fixedly connected with frame fastener 200, the other end of the inserting element 540 is defined with a bolt plunger 542; the bolt plunger 542 can be received in any one of the sliding grooves 522, and can slide in the sliding groove 522 along the length direction of the sliding groove 522, as such the inserting element 540 can be clamped and rotatably connected with the sleeve 520.

[0035] Furthermore, referring to FIG. 3, in the exemplary embodiment, an outer surface of the inserting element 540 define an odontoid structure 544; the inner surface of the sleeve 520 defines a notched structure (not labelled) which matches with the odontoid structure 544. The odontoid structure 544 matches with the notched structure, further ensuring the connecting strength between the inserting element 540 and the sleeve 520.

[0036] In detail, in the exemplary embodiment, the inserting element 540 includes a first inserting plate 546 and a second inserting plate 548 which both extend along a direction from an end of the frame fastener 200 to the box fastener 400; the first inserting plate 456 is parallel to the second inserting plate 548; the odontoid structure 544 is defined at two sides of first inserting plate 546 and two sides of the second inserting plate 548 the direction from the frame fastener 200 to the box fastener 400 (that is, the extending direction of the first inserting plate 546 and the second inserting plate 548); the position of the notched structure matches with the position of the odontoid structure 544.

[0037] When assembling, the odontoid structure 544 is misplaced with the notched structure first, and the inserting element 540 is inserted in the sleeve 520, at this time, the spring 543 of the bolt plunger 542 is in a compressed state. After the inserting element 540 is inserted in the sleeve 520 in place, the bead 545 of the bolt plunger 542 slides in one of the sliding grooves 522 by rotating the inserting element

2019100231 04 Mar 2019

540 and/or sleeve 520, at the same time, the odontoid structure 544 matches with the notched structure. When the bead 545 slides in one of the sliding grooves 522, the spring 543 of the bolt plunger 542 is in the nature state (that is a state which is uncompressed or unstretched).

[0038] When adjusting the position, the odontoid structure 544 is misplaced with the notched structure, and the inserting element 540 and/or the sleeve 520 is pulled or pushed, at this time, the spring 543 of the bolt plunger 542 is gradually compressed, the bead 545 of the bolt plunger 542 is escaped from the original sliding groove 522, and then enters into an adjacent sliding groove 522, until the bead 545 of the bolt plunger 542 is received in a proper sliding groove 522, the inserting element 540 and/or sleeve 520 is rotated until the odontoid structure 544 matches with the notched structure.

[0039] Furthermore, the portion of the sleeve 520 corresponding to the sliding groove 522 defines an opening 526, the opening 526 is used for a screwdriver passing through, as such the locking position of the bolt plunger 542 can be adjusted, and then the clamping strength between the bolt plunger 542 and the sliding groove 522 can be adjusted.

[0040] Referring to FIGS. 2-3, the box fastener 400 includes a base 420 and a clinching stud 440; the sleeve 520 and the clinching stud 440 are respectively located at two sides of the base 420; the clinching stud 440 is configured to match with a through hole (not shown) of the box of the LED display screen 300; two sides of the base 420 both define a lug 422; the lug 422 defines a gourd hole 424; the gourd hole 424 is configured to match with a clamper of the box of the LED display screen 300.

[0041] In detail, after the clinching stud 440 is inserted in the through hole of the box of the LED display screen 300, the clinching stud 440 is locked with the box of the LED display screen 300 through screw, etc. After the gourd hole 424 matches with the clamper, the clamper can be clamped in the gourd hole 424 by rotating the base 420, and then the box fastener 400 can be fixedly connected with the box of the LED display screen 300.

[0042] The technical solution of the present disclosure has simple structure and

2019100231 04 Mar 2019 low cost, and can effectively connect the box of the LED display screen 300 with the frame 100, and the location can be realized through the bolt plunger 542, the accuracy of the location is relatively high; in addition, when the frame fastener 200 is connected with the frame 100, the frame fastener is connected with the frame through the clamping mode and the hand screw 260, the operation is much simple and convenient.
