[0013] The specific implementation of the utility model is further described in detail below with reference to the accompanying drawings.

[0014] Depend on Figures 1 to 6 It is given, including an L-shaped bottom plate 1 with a lower front and a higher rear, a rectangular groove 2 is opened on the lower side of the bottom plate 1, and the left and right sides of the rectangular groove 2 are rotatably connected with the front and rear axial swing rods 3 respectively, and the front end of the swing rod 3 is provided with an up and down axial guide tube 4, the upper end of the guide tube 4 passes through the bottom plate 1 and is slidably connected with the bottom plate 1, an auxiliary rod 5 is coaxially slidably connected in the guide tube 4, and a U-shaped leg frame 6 is provided on the upper end of the auxiliary rod 5, a cylinder 7 coaxial with the guide tube 4 is rotatably connected to the swing rod 3, the upper end surface of the cylinder 7 is located on an inclined surface with a lower front and a higher rear, the lower end of the auxiliary rod 5 contacts with the upper end surface of the cylinder 7 through the up and down axial top rod 8, a connecting block 9 is slidably connected in the rectangular groove 2, and connecting rods 10 are hinged on the left and right sides of the connecting block 9, and the free end of the connecting rod 10 is hingedly connected to the swing rod 3 on its corresponding side.

[0015] In order to facilitate the forward and backward sliding of the connecting block 9, a sliding groove 11 with a forward and backward direction and an upward opening is opened on the lower side of the rectangular groove 2. The connecting block 9 is slidingly connected to the sliding groove 11. A front-to-back axial screw rod 12 is rotatably connected in the rectangular groove 2, and the screw rod 12 is threadedly connected to the connecting block 9.

[0016] In order to facilitate the rotation of the cylinder 7, the front end of the rocker arm 3 is provided with an arc-shaped air cavity 13 which is coaxial with the cylinder 7, the lower end of the cylinder 7 is provided with an air cavity 13 and a pneumatic plate 14, the rectangular groove 2 is provided with an air box 15 located behind the slider, and air pipes 16 are respectively provided on the left and right sides of the rear end of the air box 15, the free end of the air pipe 16 is connected to the air cavity 13 on the corresponding side, and the pneumatic plate 14 is connected to the inner wall of the air cavity 13 via an arc spring.

[0017] In order to facilitate squeezing the gas in the air box 15 into the air cavity 13, a front and rear axial and T-shaped push rod 17 is tightly connected in the air box 15. The front end of the push rod 17 passes through the screw rod 12 and is coaxially provided with a knob 18. The push rod 17 is slidably connected to the screw rod 12.

[0018] In order to facilitate the sliding positioning of the push rod 17, the front side of the base plate 1 is slidably connected with an auxiliary block 19 located on the left side of the push rod 17. The right side of the auxiliary block 19 is provided with a plurality of limit grooves 20 evenly distributed along the front-to-back direction and opening to the right, and the knob 18 can be inserted into the limit groove 20 on its corresponding side.

[0019] In order to facilitate restraining the patient's legs, the leg frame 6 is provided with fixing belts 21 on the left and right sides respectively, and the free ends of the fixing belts 21 are provided with Velcro respectively, and the two Velcros on the same leg frame 6 can be bonded to each other.

[0020] When the utility model is used, the patient is first made to sit on the bottom plate 1, with both legs placed in the leg frames 6 on the corresponding sides, and then the fixing belt 21 is wrapped around the patient's legs, and after adjusting the tightness, the two Velcro strips are bonded together, so that the patient's legs are restrained, which is convenient for better inspection and care of the patient's perineum;

[0021] When the distance between the patient's legs needs to be adjusted, the knob 18 is first turned to drive the screw rod 12 to rotate via the push rod 17, and the screw rod 12 drives the connecting block 9 to slide forward along the slide groove 11, so that the connecting block 9 drives the front ends of the two swing rods 3 to swing away from each other along the rectangular groove 2 via the two connecting rods 10. Since the length of the trachea 16 is long enough, it is convenient for the swing rod 3 to swing. At this time, the swing rod 3 drives the leg frame 6 to swing away from each other along the bottom plate 1 via the guide tube 4 and the auxiliary rod 5, so that the leg frame 6 drives the patient's legs to swing away from each other to a suitable angle via the fixing belt 21, and the knob 18 is no longer turned. The threaded connection has a certain self-locking property, which can keep the patient's legs at a stable angle.

[0022] When it is necessary to adjust the height of the patient's legs, first push the knob 18 to drive the push rod 17 to slide backward along the air box 15. The push rod 17 pushes the gas in the air box 15 into the air cavity 13 on its corresponding side through the air tube 16. The inflation pressure in the air cavity 13 increases. Under the action of the air pressure, the air pressure drives the cylinder 7 to rotate along the rocker rod 3 through the pneumatic plate 14, and the arc spring is compressed. The rotation of the cylinder 7 drives the auxiliary rod 5 to slide upward along the guide tube 4 through the inclined surface and the top rod 8. After the auxiliary rod 5 drives the patient's legs to move upward to a suitable height through the leg frame 6, the knob 18 is no longer pushed, and the auxiliary block 19 is pushed to slide to the right along the bottom plate 1, causing the knob 18 to be inserted into the limiting groove 20 on its corresponding side, which is convenient for the rotation positioning of the cylinder 7 and can make the leg frame 6 at a stable height, which is convenient for effectively supporting the patient's legs and facilitating better care and treatment of the patient's perineum. When support is no longer required, the above operation is repeated in reverse.

[0023] The utility model has the advantages of simple structure, convenient operation, novel conception and strong practicality. The connecting block, screw rod, connecting rod, guide tube, leg frame and fixing belt are arranged, which not only facilitates the swing of the leg frame through the relative or opposite swinging of the two swing rods, thereby driving the patient's legs to swing to a suitable angle, but also can appropriately restrain the patient's legs through the fixing belt. The air box, air tube, air cavity, pneumatic plate, cylinder, push rod, push rod and auxiliary rod are arranged, which not only facilitates the rotation of the cylinder through the flow of gas, thereby enabling the auxiliary rod to drive the patient's legs to move upward through the leg frame, but also can effectively adjust the height of the patient's legs. Under the cooperation of the two, it is not only convenient to support the patient's legs, but also convenient to expose the patient's perineum, which is beneficial for medical staff to care for and treat the patient.
