The chin support block 10 is installed on the support base 1 to support the user's chin, thereby correcting the user's head posture. The shoulder support assembly 11 is used to support the support base 1 to maintain the stability of the support base 1. The neck support assembly 12 is used to support the back of the user's head, thereby reducing the fatigue caused by the user's head continuously leaning back.

[0032] refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the shoulder support assembly 11 includes two end blocks 110 installed on one side of the support seat 1, an arc-shaped pressing plate 111 is arranged on the lower side of the end block 110, a first sliding hole 112 and a second sliding hole 115 are opened at the bottom of the end block 110, and the second sliding hole 115 has two, and the two second sliding holes 115 are symmetrical with the arc-shaped pressing plate 111 as the center, and the first sliding hole 112 is located between the two second sliding holes 115, and the interior of the first sliding hole 112 is slidably connected to the trapezoidal linkage block 1 114, a first reset spring 113 is fixed between the top of the trapezoidal linkage block 1114 and the inner top wall of the end block 110, which is used to support the arc pressure plate 111, so as to facilitate the arc pressure plate 111 to reset, and both sides of the arc pressure plate 111 are hinged with limit plates 114, and the limit plates 114 are arc-shaped, and the insides of the two arc pressure plates 111 are slidably connected with lifting plates 116, and the lifting plates 116 are provided with through holes, and the first rotating shaft 117 is movably installed inside the through holes.

[0033] Both ends of the first rotating shaft 117 are provided with connecting plates 1116, and the bottom of the connecting plates 1116 is fixed on the outer wall of the limiting plate 114. When the lifting plate 116 moves downward inside the second sliding hole 115, the limiting plate 114 is driven to rotate on the arc-shaped pressing plate 111 through the first rotating shaft 117 and the connecting plates 1116, so as to fit the back of the user. A section of the outer wall of the lifting plate 116 located inside the end block 110 is fixed with a side plate 118, and the bottom of the side plate 118 is fixed to the side plate 118. A second return spring 119 is fixed between the inner bottom wall of the end block 110 for supporting the side plate 118, thereby facilitating the return of the limit plate 114 through the lifting plate 116. A linkage block 1110 is provided inside the end block 110, and the linkage block 1110 has an arc surface on the side facing the trapezoidal linkage block 1114. An inclined block 1115 is fixed to the bottom of the linkage block 1110 for pushing the lifting plate 116 downward, thereby facilitating the adjustment of the angle of the limit plate 114.

[0034] A third reset spring 1113 is fixed between one side of the linkage block 1110 and the inner wall of the end block 110, which is used to support the linkage block 1110, so as to facilitate the reset of the linkage block 1110. A slide rail 1111 is fixed to the inner top wall of the end block 110, and a sliding plate 1112 is slidably connected to the inner top wall of the slide rail 1111. The bottom of the sliding plate 1112 is fixed to the top of the corresponding linkage block 1110, which is used to support the linkage block 1110, so as to maintain the stability of the linkage block 1110.

[0035] When the bracket is placed on the user's shoulder, the user's chin is placed on the chin support block 10, and the arc pressure plate 111 is against the user's shoulder, and the user's shoulder will drive the arc pressure plate 111 to move upward. At this time, the arc pressure plate 111 drives the trapezoidal linkage block 1114 to move upward inside the end block 110, and the trapezoidal linkage block 1114 pushes the linkage block 1110 to compress the third return spring 1113. Since the top to the bottom of the inclined block 1115 is inclined, and the initial position of the lifting plate 116 is located at the top of the inclined block 1115.

[0036] When the linkage block 1110 slides toward the third return spring 1113, the inclined block 1115 of the linkage block 1110 drives the lifting plate 116 to move downward. At this time, the lifting plate 116 slides from the top end of the inclined block 1115 to its bottom end, and the lifting plate 116 drives the limiting plate 114 to rotate on the arc pressure plate 111 through the first rotating shaft 117 and the side plate 118, so that the two arc pressure plates 111 are respectively attached to the back and front of the user, thereby maintaining the stability of the end block 110.

[0038] A plurality of first limiting grooves 127 are provided on the rotating disk 124, and the plurality of first limiting grooves 127 are arranged in a ring shape on the rotating disk 124, for accommodating the first limiting protrusions 126, so as to facilitate the first limiting protrusions 126 to limit the rotating disk 124, and fourth reset springs 125 are fixed to the tops of the plurality of first limiting protrusions 126, and the tops of the plurality of fourth reset springs 125 are fixed to the inner top wall of the hollow concave block 121, for supporting the first limiting protrusions 126, so as to facilitate the first limiting protrusions 126 to reset.

[0039] When the bracket is placed on the user's shoulder, the rotating member 122 is rotated, and the first limiting protrusion 126 can slide from the corresponding first limiting groove 127 to the surface of the rotating disk 124. After the angle adjustment of the rotating member 122 is completed, the first limiting protrusion 126 can be inserted into the corresponding first limiting groove 127, so that the connecting member 123 on the rotating member 122 is against the back of the user's head. The first limiting protrusion 126 can maintain the stability of the bracket because the connecting member 123 is against the back of the user's head. At the same time, the user's neck can be relaxed, reducing the user's neck fatigue.

[0040] refer to Figure 2 and Figure 3 As shown, a receiving slot 13 is provided on one side of the support seat 1 facing the end block 110 , and a limiting assembly 20 is installed inside the receiving slot 13 for limiting the end block 110 , thereby maintaining the stability of the end block 110 .
