Therefore, when one end of the protrusion 3 at the top end of the supporting frame 2 and the connecting block 31 pass through the opening 428 between the first partition plate 426 and the second partition plate 427 and then enter the limiting groove 55 of the transfer frame 5, the two sides of the first horizontal ribs 53 and the second horizontal ribs 54 are pressed by being guided by the top end of the guide groove 551, so that the connecting block 31 and one end of the protrusion 3 can be limited simultaneously; after the second connecting portion 64 of the connecting member 6 is screwed upwards to pass through the limiting hole 415 on the bottom surface of the adapter 41, the second connecting portion 64 continues to pass upwards through the circular hole 56 on the bottom surface of the adapter frame 5 and the avoiding groove 33 on the bottom end of the connecting block 31 to lock and connect the first connecting portion 34 on the bottom surface of the connecting block 31, so that the connecting block 31 and one end of the protruding portion 3 are stably combined with the neck quick-release member 4 at the same time, and the shaking is eliminated by the adapter frame 5 together with the annular elastic washer 65, so that the connecting member 6 can still be stably combined with the connecting block 31 and is not easy to loosen after the whole is adjusted and lifted for many times. As shown in fig. 5, after the handle 62 is unfolded and rotated in the opposite direction to release the first connecting portion 34 and the second connecting portion 64, the connecting block 31 and one end of the protruding portion 3 can be quickly separated from the neck quick-release member 4, and since the outer diameter of the second connecting portion 64 of the connecting member 6 is larger than the inner diameter of the screw thread of the limiting hole 415 of the adapter 41, the second connecting portion 64 of the connecting member 6 can be limited in the limiting groove 55 of the adapter 5 and cannot be separated from the adapter 41.

Based on the structure, the utility model discloses be equipped with the slider in the first half of support frame, the one end of slider has the bulge, and the one end of bulge has the connecting block, and the connecting block is through a connecting piece with the mutual lock joint of mode that can release with neck quick detach spare, can make things convenient for the equipment or dismantle. The adapter frame made of the POM material is correspondingly locked in the positioning groove of the adapter seat, the two opposite sides of the connecting block respectively extend downwards to form abutting connection with the plurality of convex ribs on the inner wall surface of the adapter frame, the gap can be eliminated, the abutting effect can be generated, and after the connecting block is locked by the connecting piece, the display is stably assembled on one side of the top end of the support frame. And, because the bottom of the connecting block forms one and keeps away the position groove, can guide the position locked effectively, in order to lock connecting piece and connecting block fast. When the connecting block is separated from the neck quick-dismantling piece, the connecting piece is retained on the adapter, so that the connecting block can be prevented from being lost or forgotten by workers, and the space occupied by separating each element is saved in the transportation process. In addition, because the bottom of the bulge extends downwards to form a supporting part, and the supporting part is positioned at the front side of the constant force spring, the structural strength can be effectively increased, the display can be safely hung, and the effect of protecting the constant force spring can be achieved.

Although the present invention has been described with reference to specific preferred embodiments for achieving the above objects, it is not intended to limit the present invention to the specific features of the present invention, and it should be understood by those skilled in the art that any changes or modifications that can be easily conceived are possible and covered by the claims of the present invention.
