The elastic bracket buckle 42 adopts any structure of the clamping seat of the existing neck support, which can realize the fast connection of the clamping seat 4 to the side of the U-shaped bracket 3, or the fast removal of the elastic bracket buckle from the side of the U-shaped bracket 3.

[0025] The connecting belt locking member 43 of the utility model is provided with a connecting belt channel 431 for the connecting belt to pass through, the cross-sectional width of the connecting belt channel 431 is greater than the thickness of the connecting belt 2, and a one-way block 432 corresponding to the connecting belt channel is provided on the connecting belt locking member 43; Figure 5 As shown, when the connecting belt locking member 43 is pushed, there is a movable space in the connecting belt channel 431 for the connecting belt 2 to move; the base 41 is provided with an elastic support member 45 for applying elastic force to the inner side of the connecting belt locking member 43 so that the one-way block 432 on the connecting belt locking member 43 cooperates with the latching teeth 21 on the connecting belt 2; the elastic support member 45 is a cylindrical elastic support body made of elastic material; the base 41 is provided with a support body positioning groove 411 for the elastic support member to lie horizontally and position. The elastic material is preferably a silicone material, which has the elasticity of a metal spring and avoids the influence of the metal material on the X-ray inspection. A connecting belt limiting hole 441 for the connecting belt to freely enter and exit is provided on the shell 44 at a position corresponding to the connecting belt channel 431, and an unlocking operation hole 442 is provided at a position corresponding to the outer side of the connecting belt locking piece 43. When the connecting belt locking piece 43 is pressed through the unlocking operation hole 442, the connecting belt 2 is supported by the connecting belt limiting hole 441 on the shell, and the one-way clamping block 432 on the connecting belt locking piece 43 is separated from the clamping tooth 21 on the connecting belt, so that the connecting belt 2 can be freely pulled out from the clamping seat 4, thereby achieving the purpose of releasing the connecting belt 2.

[0026] In order to prevent the connection belt limiting hole 441 of the shell 44 from causing a jamming effect on the process of releasing the connection belt 2, the latching tooth 21 is arranged at a non-edge position of the connection belt, and the connection belt 2 is provided with smooth support areas 22 on both sides of the latching tooth 21; the connection belt limiting hole 441 on the shell 44 is a T-shaped hole, and the two sides of the connection belt limiting hole 441 are slidably matched with the smooth support areas 22 on the connection belt 2, that is, the connection belt limiting hole 441 does not hinder the insertion or withdrawal of the connection belt 2, and when the connection belt locking member 43 is pressed, the connection belt 2 and the shell 44 will not be displaced. The preferred solution is: an extension part 434 is provided on the connection belt locking member 43 at the exit of the connection belt channel, and the one-way block 432 is provided on the extension part 434. In the specific implementation process, in order to avoid the connection belt limiting hole 441 of the shell 44 causing a jamming effect on the process of releasing the connection belt 2, the hole edge of the connection belt limiting hole 441 of the shell 44 can also be designed to be an inclined structure to prevent the connecting belt 2 from being stuck at the hole edge of the connection belt limiting hole 441.

[0027] The connecting belt locking member 43 comprises a square main body and a button portion 433 protruding from the square main body, and the button portion 433 is placed in the unlocking operation hole 442 on the housing. The outer surface of the button portion 433 is provided with a pressing anti-slip pattern on one side corresponding to the one-way block 432 of the connecting belt locking member; when the connecting belt 2 needs to be released, the one-way block 432 on the connecting belt locking member 43 is pressed on the anti-slip pattern, and the one-way block 432 on the connecting belt locking member 43 is separated from the latching teeth 21 on the connecting belt.

[0028] In order to achieve uniform force support for the connecting belt locking member 43, there are two elastic support members 45, which are respectively supported at positions corresponding to the inner side surface of the connecting belt locking member 43 and the entrance and exit of the connecting belt channel.

[0029] In order to guide and position the connecting belt 2 during the insertion or extraction process of the connecting belt 2 into the card seat 4, a longitudinal guide groove 23 is provided on the outer side of the connecting belt 2, and a guide limit block 443 cooperating with the guide groove 23 is provided on the inner side of the shell 44.
