A sliding cavity is provided at the bottom of one side of the support seat 2, and a slide plate 11 is provided in the sliding cavity. One end of the slide plate 11 extends out of the sliding cavity and is connected to the support plate 12 through an angle adjustment component. A pair of first straps 13 and a pair of second straps 14 are respectively provided on the support plate 12, and the first straps 13 and the second straps 14 are bonded by Velcro, and the base 1 and the horizontal plate 6 are connected by a lifting component.

[0031] By adopting the above technical solution, the angle of the support seat 2 can be adjusted through the transmission of the rotating cylinder 7 and the gear, so that the patient's ankle joint can be automatically turned inward or outward, thereby adjusting to a position suitable for filming. The design of the support plate 12 and the strap ensures the fixation of the foot to prevent movement during the filming process. The design of the lifting assembly makes the height of the support seat 2 adjustable to accommodate patients of different heights. The doctor does not need to manually adjust the patient's ankle joint, but only needs to control the rotating cylinder 7 to adjust the position of the patient's ankle joint, thereby reducing the doctor's contact time with X-rays and improving the protection of the doctor.

[0032] This embodiment is further configured as follows: the angle adjustment assembly includes a pair of supports 15 arranged at one end of the skateboard 11, an adjustment shaft 16 is rotatably installed between the pair of supports 15, the lower end of the support plate 12 is fixedly connected to the adjustment shaft 16, one end of the adjustment shaft 16 passes through one side support 15 and is fixedly installed with an adjustment wheel 17, the outer circle of the adjustment wheel 17 is provided with a plurality of positioning holes 18 along the circumferential direction, the side wall of the skateboard 11 is provided with a positioning frame 19, the positioning frame 19 is provided with a through hole, a positioning pin 20 is slidably inserted in the through hole, one end of the positioning pin 20 is inserted into the positioning hole 18, and the other end is fixedly provided with a pull plate 21, and a return spring 22 is installed between the pull plate 21 and the positioning frame 19.

[0044] This embodiment is further configured such that a fixing seat for fixing the rotating cylinder 7 is provided on the transverse plate 6 .

[0045] By adopting the above technical solution, the design of the fixing seat improves the reliability of the rotary cylinder 7 and ensures the stability of the transmission.

[0046] By those skilled in the art, the components in this case are connected in sequence. The specific connection and operation sequence should refer to the following working principle. The detailed connection means are well-known technologies in the field. The following mainly introduces the working principle and process.

[0047] Embodiment: During the inspection, the height of the support seat 2 can be adjusted according to the inspection requirements. The wire drawing rod 23 can be rotated to make the pair of sliders 25 screwed thereon move relative to each other, and then the pair of connecting rods 26 push the cross plate 6 and the slide seats 4 on both sides to slide up and down to achieve the height adjustment of the support seat 2. After the adjustment is completed, the patient puts the leg into the leg support cavity of the support seat 2, and makes the foot close to the support plate 12, and fixes the leg with the Velcro strap 27 to ensure the stability of the leg, and then fixes the patient's foot to the support plate 12 with the first strap 13 and the second strap 14 to ensure the stability of the foot, and then adjusts the inclination angle of the support plate 12 and the foot according to the shooting requirements, and the pull plate 21 can be pulled to separate the positioning pin 20 from the positioning hole 18. At this time, the adjustment can be rotated. The section wheel 17 rotates the adjustment shaft 16, thereby driving the support plate 12 and the patient's foot to flip over. After flipping to a suitable angle, the pull plate 21 is released, and the reset spring 22 drives the positioning pin 20 to reset, so that the positioning pin 20 is reinserted into the corresponding positioning hole 18, thereby fixing the adjustment wheel 17 and the support plate 12. At this time, the patient's ankle joint can be filmed. When the patient's ankle joint needs to be inverted or everted, the rotating cylinder 7 is driven by compressed air to rotate the main gear 8. The main gear 8 and the sub-gear 9 cooperate to rotate the rotating shaft 5, adjust the angle of the support seat 2, and realize automatic flipping of the ankle joint. By controlling the rotating cylinder 7, the angle of the support seat 2 is made to reach a position suitable for filming, which meets different filming requirements and is easy to use.

[0048] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions. The sentence "includes an element defined by ... does not exclude the existence of other identical elements in the process, method, article or device including the element".

[0049] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
