A second connecting arm 111 is arranged at intervals on one side of the lower support plate 110, and the second connecting arm 111 is arranged corresponding to the first connecting arm 101. The first end of the sliding rod 104 is connected to the first connecting arm 101, and the second end of the sliding rod 104 is slidably connected to the second connecting arm 111. The positioning device 120 is rotatably arranged on the upper support plate 100 close to the side of the lower support plate 110. The positioning device 120 is bound to the user's leg through a strap, and the user can continuously rotate the calf at a fixed angle.

[0039] By setting the sliding rod 104, the upper support plate 100 and the lower support plate 110 can slide relative to each other, and move closer to or away from each other by sliding. The lower support plate 110 is used to place the user's thigh. The bandage is stably wrapped around the user's thigh through the through groove, the sinking groove and the abutment strip, and the positioning device 120 is used to assist in binding the bandage, so as to improve the stability of fixing the user's thigh.

[0040] See also Figure 2 , Figure 3 As shown, the knee joint auxiliary rotation brace also includes a rotation positioning seat 121, a clamping arm 125 and a fixing arm 126.

[0041] The rotational positioning seat 121 is arranged on the upper support plate 100 close to the side of the lower support plate 110. The rotational positioning seat 121 includes a connecting portion 122 connected to the upper support plate 100, and a bearing portion 123 connected to the connecting portion 122. The connecting portion 122 and the bearing portion 123 are cylindrical structures. The radial dimension of the bearing portion 123 is smaller than the radial dimension of the connecting portion 122. A plurality of positioning holes 124 are arranged around the outer periphery of the bearing portion 123. The positioning device 120 includes a circular clamping arm 125 with an opening at one end, and a fixed arm 126 connected to the clamping arm 125. The fixed arm 126 is integrally arranged with the clamping arm 125. The fixed arm 126 is a straight plate structure. Positioning balls 127 are arranged at intervals on the inner side of the connecting arm. The positioning balls 127 are arranged corresponding to the positioning holes 124. The positioning device 120 is installed on the bearing portion 123 by snapping the clamping arm 125, and the fixed arm 126 is bound to the user's calf by a strap.

[0042] By adopting the above technical solution, through the setting of the rotating positioning seat 121, the clamping arm 125 and the fixed arm 126, since the clamping arm 125 is a circular ring structure with one end open, the clamping arm 125 can be buckled on the outer periphery of the bearing part 123, and through the setting of the positioning hole 124 and the positioning ball 127, the clamping arm 125 can be fixed at any angle through the positioning ball 127 and the positioning hole 124 after rotation.

[0043] See also Figure 2 As shown, the positioning device 120 also includes a through groove 128, which is arranged on the side wall of the fixed arm 126 and is used to pass a bandage.

The rotating cover 129 is also connected to the clamping arm 125. A avoidance groove 130 for avoiding the fixed arm 126 is provided on one side of the rotating cover 129. By setting the rotating cover 129, the assembly stability of the clamping arm 125 and the fixed arm 126 is improved, and the fixed arm 126 is rotated by toggling it.

[0045] See also Figure 1 As shown, the lower support plate 110 is provided with sinking grooves 114 at intervals, and the sinking grooves 114 are provided on the lower support plate 110 near the side of the upper support plate 100, and abutting strips 115 are provided in the sinking grooves 114. The sinking grooves 114 and the abutting strips 115 are used to cooperate with the fixed arm 126 to bind the bandage, and the bandage is bound to the user's thigh through the bandage. Through the setting of the sinking grooves 114, after the bandage passes through the through grooves 128 on the fixed arm 126, the bandage goes around the user's leg, and then the bandage is passed into the sinking grooves 114 from one side of the abutting strip 115, and then passes out of the sinking grooves 114 through the other side of the abutting strip 115, and the bandage is stably wrapped around the user's thigh through the through grooves 128 of the fixed arm 126, the sinking grooves 114 and the abutting strips 115, thereby improving the stability of fixing the user's thigh.

[0046] See also Figure 1As shown, the first connecting arm 101 includes a first arc portion 102 connected to the upper support plate 100 and a first straight arm portion 103 extending toward the lower support plate 110, and the second connecting arm 111 includes a second arc portion 112 connected to the lower support plate 110 and a second straight arm portion 113 extending toward the upper support plate 100. The second straight arm portion 113 provides a sliding range for the sliding of the sliding rod 104. The arrangement of the first arc portion 102 and the second arc portion 112 improves the safety of the knee joint auxiliary rotation brace and reduces the damage caused by collision during use.

[0047] See also Figure 1 As shown, the knee joint auxiliary rotation brace also includes an adjustment knob 116, which is rotatably arranged on one side of the second straight arm portion 113. The adjustment knob 116 is arranged through the second straight arm portion 113 and is used to adjust the fixed slide bar 104. Through the setting of the adjustment knob 116, after sliding and adjusting the distance between the upper support plate 100 and the lower support plate 110, the slide bar 104 is fixed by adjusting and tightening the adjustment knob 116.

[0048] See also Figure 1 As shown, a positioning circular groove 117 is provided on the lower support plate 110 near the upper support plate 100. The positioning circular groove 117 is used to assist the user in placing the knee joint, so as to facilitate the user to place the leg.

[0049] To summarize, the overall structure of the knee joint auxiliary rotation brace provided by the present application is simple. When taking multi-angle photos of the user's knee joint, the strap is tied to the user's thigh through the sinking groove 114 and the abutment bar 115 on one side to fix the user's thigh, and then the strap is tied to the calf and the fixed arm 126 through the sinking groove 114 and the abutment bar 115 on the other side, and the upper support plate 100 is lowered to cooperate with the lower support plate 110 to clamp the user's thigh, so that the fixed arm 126 fits on the user's calf. After taking a knee joint image, the calf is driven to rotate continuously at a continuous angle by rotating the fixed arm 126, and finally a knee joint image of the continuously rotating calf is obtained.

[0050] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
