[0026] In the embodiment of the present disclosure, a switching protrusion 2021 is provided inside the positioning block 202, and a switching groove is provided outside the switching rod 203, and the switching protrusion 2021 is inserted into the inside of the switching groove, and the switching groove is composed of a locking groove 2031 with an arc direction and a guide groove 2032 with a spiral direction, and the locking groove 2031 is connected to one end of the guide groove 2032. In use, when the positioning assembly 2 is in a reset state (the switching rod 203 is not rotated by external force), it is in a threaded adjustment mode. At this time, the switching protrusion 2021 is located inside the locking groove 2031, which limits the radial movement of the positioning block 202 on the adjusting screw 102, that is, the positioning block 202 cannot move in the radial direction of the adjusting screw 102, so that the adjusting screw 102 can stably cooperate with the side thread of the positioning block 202 to achieve locking adjustment. The screw 102 and the support frame 103 have the function of adjusting the use height, and in this state, the use height of the support frame 103 can be slowly and finely adjusted by directly rotating the regulating knob 201. When the regulating knob 201 rotates, it can drive the positioning block 202 to rotate synchronously. A track groove 1021 is provided inside the adjusting screw 102, and a track block 1011 is provided inside the fixing column 101. The track block 1011 is inserted into the track groove 1021. Under the cooperation of the track block 1011 and the track groove 1021, the adjusting screw 102 cannot rotate. Therefore, when the positioning block 202 rotates, the rod thread of the adjusting screw 102 can drive the adjusting screw 102 to rise and fall to change the use height, thereby changing the use height of the support frame 103. The regulation is convenient and flexible, the support height can be finely controlled, and the use is stable.

[0027] In the embodiment of the present disclosure, a switching rack 2041 is provided on the side of the reset block 204, and a switching gear 2033 is provided on the outside of the switch rod 203. The gear teeth of the switching rack 2041 and the switching gear 2033 are meshed for transmission. A reset top spring 2042 is provided at the bottom of the reset block 204, and the two ends of the reset top spring 2042 are respectively against the inside of the reset block 204 and the inside of the regulating rotary block 201. Under the action of the reset top spring 2042, when the switch rod 203 is not rotated by external force, the switching protrusion 2021 is located inside the locking groove 2031, and the side of the positioning block 202 and the adjusting screw 102 are threadedly matched. In use, when the positioning assembly 2 is adjusted to a pulling adjustment mode, it is only necessary to rotate the switch rod 203. When the switch rod 203 rotates, it can guide the switching protrusion 2021 into the guide groove 2032, thereby When the switching rod 203 is subsequently rotated, the guide groove 2032 can drive the positioning block 202 to move in the direction away from the adjusting screw 102 through the switching protrusion 2021, thereby releasing the threaded matching relationship between the adjusting screw 102 and the positioning block 202, that is, the locking state of the adjusting screw 102 is released. After that, the function of adjusting its use height can be achieved by directly pulling the adjusting screw 102. The regulation is convenient and fast. At the same time, during the rotation of the switching rod 203, the switching gear 2033 can drive the reset block 204 to move downward through the switching rack 2041 and compress the reset top spring 2042 to store energy. When the adjusting screw 102 is adjusted to the appropriate height, the switching rod 203 is released and then the positioning assembly 2 can automatically reset and restore the threaded adjustment mode under the action of the reset top spring 2042 and lock the current use height of the adjusting screw 102. It is flexible and convenient to use.

[0028] The specific usage and function of this embodiment are as follows:

[0029] In the present invention, the height of the support frame 103 is adjusted according to the actual inspection needs. The positioning component 2 has two usage modes: threaded height adjustment and height adjustment when pulling. The appropriate adjustment mode can be selected as needed. When the positioning component 2 is in the reset state (the switching rod 203 is not rotated by external force), it is in the threaded adjustment mode. At this time, the switching protrusion 2021 is located inside the locking groove 2031, which limits the movement of the positioning block 202 in the radial direction of the adjusting screw 102, that is, the positioning block 202 cannot move in the radial direction of the adjusting screw 102, so that the adjusting screw 102 can be stably adjusted with the positioning block The side threads of 202 cooperate to realize the function of locking the adjustment screw 102 and the support frame 103 in the use height. In this state, the use height of the support frame 103 can be slowly and finely adjusted by directly rotating the adjustment knob 201. When the adjustment knob 201 rotates, it can drive the positioning block 202 to rotate synchronously. Under the cooperation of the track block 1011 and the track groove 1021, the adjustment screw 102 cannot rotate. Therefore, when the positioning block 202 rotates, the rod thread of the adjustment screw 102 can drive the adjustment screw 102 to rise and fall to change the use height, thereby changing the use height of the support frame 103. The invention is convenient and flexible, and the supporting height can be finely controlled. When the positioning assembly 2 is adjusted to the pull-type adjustment mode, it is only necessary to rotate the switching rod 203. When the switching rod 203 is rotated, the switching protrusion 2021 can be introduced into the guide groove 2032, so that when the switching rod 203 is subsequently rotated, the guide groove 2032 can drive the positioning block 202 to move in a direction away from the adjusting screw 102 through the switching protrusion 2021, thereby releasing the threaded matching relationship between the adjusting screw 102 and the positioning block 202, that is, the locking state of the adjusting screw 102 is released, and the adjusting screw 102 can be directly pulled thereafter. 102 can realize the function of adjusting its use height, and the adjustment is convenient and fast. At the same time, when the switching rod 203 is rotated, the switching gear 2033 can drive the reset block 204 to move downward through the switching rack 2041 and compress the reset top spring 2042 to store energy. When the adjusting screw 102 is adjusted to a suitable height, the switching rod 203 is released and then the positioning component 2 can automatically reset and restore the threaded adjustment mode under the action of the reset top spring 2042 and lock the current use height of the adjusting screw 102. After the adjustment is completed, the patient lies on the examination bed and supports his legs with the support frame 103, and then various inspection operations can be started.

[0030] In another embodiment, the fixing column 101 is rotatably connected to the top of the mounting fixture 104. This design enables the support frame 103 to freely rotate to adjust the support angle, thereby improving the comfort of supporting the patient's legs.
