[0018] 2. The cross slider is driven to rotate by the threaded adjustment rod, and the cross slider drives the limit slider to move through the force transmitted by the extrusion spring. When the patient has been fitted with the mammography machine, the cross slider will move relative to the limit slider to further compress the extrusion spring. When the cross slider contacts the travel limit switch, the travel limit switch will send a signal to stop the drive motor from working, to avoid the situation where the patient is already fitted with the mammography machine and the device still pushes and squeezes the patient under misoperation, thus playing a certain protective role.

[0019] 3. Starting the adjustment motor can drive the adjustment screw to rotate, and the second threaded sleeve cooperates with the adjustment screw thread, so that the rotation of the adjustment screw can drive the seat cushion to move up and down as a whole, thereby adjusting the height of the affected breast, so that the patient's breast is aligned with the height of the breast molybdenum target machine support plate.

[0020] 4. After loosening the extrusion nut, the limit collar will reset under the push of the return spring. At this time, the limit block will move out of the limit slot, releasing the restriction on the backrest. At this time, the backrest can be easily rotated to adjust the angle and adjust the inclination angle of the backrest so that when the patient is sitting, both breasts can be kept as vertical as possible on the pallet of the breast molybdenum target machine.

[0032] In this embodiment, the first threaded sleeve 307 is threadedly matched with the threaded adjustment rod 102. Rotating the threaded adjustment rod 102 can drive the cross slider 306 to move. The movement of the cross slider 306 will drive the limit slider 3 to move. The limit slider 3 is used to drive the support frame 2 and the seat cushion 4 to move synchronously. After the patient sits on the seat cushion 4, the threaded adjustment rod 102 can be used to control the device to continuously approach the breast molybdenum target machine, and the patient does not need to pull and adjust it by himself. Secondly, the seat cushion 4 is slidably matched with the connecting through hole 202 through the limit connecting rod 401, and is slidably installed above the support frame 2. The seat cushion 4 can move up and down to adjust the height, and then the height of the patient sitting on the seat cushion 4 is adjusted, so that the patient's bilateral breasts can be placed on the breast molybdenum target machine tray according to the shooting position requirements.

[0033] Example 2

[0034] A driving motor 103 is fixedly connected to one side of the base 1, and the output end of the driving motor 103 is fixedly connected to the threaded adjustment rod 102. A sliding wheel 201 is symmetrically installed at the front and rear sides of the support frame 2 near the lower edge. A second threaded sleeve block 203 is embedded and installed on the support frame 2. Avoidance holes 301 are opened on both sides of the limit slider 3. The avoidance holes 301 are communicated with the inside of the cross slide 302. A sleeve rod 303 is symmetrically fixed in the cross slide 302, and an extrusion spring is sleeved on the sleeve rod 303. Spring 304, a through hole is opened in the cross slider 306, the through hole and the sleeve rod 303 are slidably matched, the cross slide 302 is embedded with a travel limit switch 305, the travel limit switch 305 and the cross slider 306 cooperate with each other, the lower end of the limit connecting rod 401 is fixedly connected to a support frame 402, the support frame 402 is fixedly connected to an adjusting motor 403, the output end of the adjusting motor 403 is fixedly connected to an adjusting screw 404, and the adjusting screw 404 is threadedly matched with the second threaded sleeve block 203.

[0035] In this embodiment, the threaded adjustment rod 102 can be driven to rotate by starting the driving motor 103, and the rotation of the threaded adjustment rod 102 drives the cross slider 306 to move. The movement of the cross slider 306 compresses the squeezing spring 304, and the squeezing spring 304 transmits the force to the inner wall of the cross slide 302. The cross slider 306 drives the limit slider 3 to move by the squeezing spring 304, and the movement of the limit slider 3 drives the upper support frame 2 and the cushion 4 to move. When the patient has been fitted with the breast mammography machine, the patient's body will apply a certain amount of reverse thrust to the device, and then the squeezing spring 304 will be further compressed. When the cross slider 306 is aligned with the stroke When the limit switch 305 is in contact, the travel limit switch 305 will send a signal to stop the driving motor 103 from working, so as to avoid the patient being pushed and squeezed by the breast molybdenum target machine device when the patient is already in contact with the breast molybdenum target machine device due to misoperation, thereby playing a certain protective role. Starting the adjustment motor 403 can drive the adjustment screw 404 to rotate, and the second threaded sleeve block 203 and the adjustment screw 404 thread are matched, so that the rotation of the adjustment screw 404 can drive the seat cushion 4 to move up and down as a whole. By using the sliding wheel 201 to contact the base 1, the friction can be minimized, so that the device can move forward and backward easily, and the avoidance hole 301 can prevent the limit slider 3 from interfering with the threaded adjustment rod 102.

[0036] Example 3

[0038] In this embodiment, the backrest 5 is rotatably installed on the seat cushion 4 by rotating the connecting screw 502, the connecting shaft 505 and the hinge seat 405, and the inclination angle of the backrest 5 is adjusted so that when the patient is sitting, the bilateral breasts can be kept as vertical as possible on the breast molybdenum target machine support plate, and tightening the extrusion nut 7 can squeeze the limiting ring 6, and the limiting ring 6 will be squeezed and fit against the side of the hinge seat 405. At this time, the limiting block 602 will be stuck in the limiting slot 406, and the limiting slot 406 and the limiting block 602 cooperate with each other to limit the rotation of the backrest 5 and keep the backrest 5 at a specified inclination angle. When the extrusion nut 7 is loosened, the limiting ring 6 will be reset under the push of the return spring 504, and the limiting block 602 will move out of the limiting slot 406 to release the restriction on the backrest 5, and the backrest 5 can be easily rotated to adjust the angle.

[0039] The working principle and use process of the present invention are as follows: when in use, the patient needs to sit directly on the cushion 4, maintain a sitting posture, so that the back is in contact with the backrest 5, and then loosen the squeezing nut 7 to release the restriction on the backrest 5. When adjusting the angle of the backrest 5, the patient's bilateral breasts are in a relatively vertical state. After adjusting the backrest 5 to a suitable angle, the squeezing nut 7 can be tightened again to fix the angle of the backrest 5, and the adjusting motor 403 is started to drive the adjusting screw 404 to rotate. The rotation of the adjusting screw 404 can drive the cushion 4 to move, and then adjust the height of the affected breast, so that the patient's breast is aligned with the height of the breast molybdenum target machine support plate, and finally start the driving motor 103 to drive the threaded adjusting rod 102 to rotate. The rotation of the threaded adjusting rod 102 will drive the cushion 4 to move through the limiting slider 3, so that the patient is in contact with the breast molybdenum target machine, so that the patient's bilateral breasts can be placed on the breast molybdenum target machine support plate according to the shooting position requirements.
