In addition, some orthopedic traction devices cannot be adjusted at multiple angles, making it impossible for some patients to exercise in the most comfortable posture.

[0005] The technical solution adopted by the present invention to solve the technical problem is: to provide an auxiliary traction device for trauma orthopedics, including: a moving device, a clamping device and a positioning device;

[0006] The mobile device comprises an electric telescopic rod, a first connecting rod, a second connecting rod and a bottom plate, wherein the three electric telescopic rods and the second connecting rod are respectively located at the top of the bottom plate at equal angles, and the electric telescopic rod and the second connecting rod are respectively hinged to the bottom plate, the first connecting rod is located at the top of the second connecting rod, one end of the first connecting rod is hinged to an end of the second connecting rod away from the bottom plate, one side of the second connecting rod is hingedly provided with an electric telescopic rod, a top plate is provided on the top of the first connecting rod, and an end of the first connecting rod away from the second connecting rod is hinged to the top plate;

[0008] The positioning device includes a first fixed platform and a second movable platform, the first fixed platform and the second movable platform are two semi-cylinders, the first fixed platform and the second movable platform are respectively located on the top of the top plate, the first fixed platform is fixedly connected to the top plate, a rack is provided on one side of the first fixed platform, a notch is provided on the side of the second movable platform close to the rack, the notch passes through the second movable platform, the rack passes through the notch and extends to the inside of the second movable platform, a square cavity is provided inside the second movable platform, a gear is rotatably provided on the top of the square cavity, and the gear and the rack are meshed with each other.

[0009] During operation, according to the needs of the patient, if double-leg exercise is performed, the two clamping devices are placed in the second slots on both sides of the first fixed platform; if single-leg exercise is performed, one clamping device is placed in the second slot in the middle, and then the second motor is started. The rotation of the second motor drives the gear to rotate. Since the gear and the rack are meshed with each other, and the rack is fixedly connected to the top plate, the gear drives the second mobile platform to move. The movement of the second mobile platform will squeeze and fix the clamping device. By starting the first motor, the rotation of the first motor drives the first gear to rotate, and the rotation of the first gear drives the second gear to rotate in the opposite direction.

[0038] The positioning device 30 includes a first fixed platform 3001 and a second movable platform 3002. The first fixed platform 3001 and the second movable platform 3002 are two semi-cylinders. The first fixed platform 3001 and the second movable platform 3002 are respectively located on the top of the top plate 1005. The first fixed platform 3001 is fixedly connected to the top plate 1005. A rack 3007 is provided on one side of the first fixed platform 3001. A notch is provided on the side of the second movable platform 3002 close to the rack 3007. The notch passes through the second movable platform 3002. The rack 3007 passes through the notch and extends to the interior of the second movable platform 3002. A square cavity is provided inside the second movable platform 3002. A gear 3011 is rotatably provided on the top of the square cavity. The gear 3011 and the rack 3007 are meshed with each other.

[0039] During operation, according to the needs of the patient, if it is a double-leg exercise, the two clamping devices 20 are placed in the second slots 3009 on both sides of the first fixed platform 3001; if it is a single-leg exercise, one clamping device 20 is placed in the middle second slot 3009, and then the second motor 3013 is started, and the second motor 3013 rotates to drive the gear 3011 to rotate. Since the gear 3011 and the rack 3007 are meshed with each other, and the rack 3007 is fixedly connected to the top plate 1005, the gear 3011 drives the second movable platform 3002 to move.

If three electric telescopic rods 1001 are activated at the same time, When the electric telescopic rod 1001 is retracted, the top plate 1005 can be driven down by the swing of the three groups of first connecting rods 1002 and second connecting rods 1003. Conversely, the top plate 1005 can be driven up by the swing of the three groups of first connecting rods 1002 and second connecting rods 1003, so that the patient can get multi-directional, multi-angle and multi-height exercise. When the device is not in use, the three electric telescopic rods 1001 can be started to retract, so that the top plate 1005 is lowered to the lowest height. In this state, the first connecting rod 1002 and the second connecting rod 1003 are folded with each other for easy storage.

The user's legs can be heated by the setting of the heating block 3006 to further promote blood circulation.

[0050] The specific workflow is as follows:

[0051] According to the needs of the patient, if the patient is doing double-leg exercise, two clamping devices 20 are placed in the second slots 3009 on both sides of the first fixed platform 3001. If the patient is doing single-leg exercise, one clamping device 20 is placed in the middle second slot 3009, and then the second motor 3013 is started. The second motor 3013 rotates to drive the gear 3011 to rotate. Since the gear 3011 and the rack 3007 are meshed with each other, and the rack 3007 is fixedly connected to the top plate 1005, the gear 3011 drives the second mobile platform 3002 to move.

When the patient puts his legs between the two clamp rings 2002, the first gear 2005 is rotated in the opposite direction to make the two clamp rings 2002 move closer to each other, thereby clamping the patient's legs. Then, one of the electric telescopic rods 1001 is started according to the direction the patient needs to rotate. When the electric telescopic rod 1001 contracts, the electric telescopic rod 1001 drives the second connecting rod 1003 to swing, and the second connecting rod 1003 drives the first connecting rod 1002 to swing, thereby driving the top plate 1005 to deflect in the direction of the activated electric telescopic rod 1001. When the three electric telescopic rods 1001 are started to retract, the three groups of first connecting rods 1002 and second connecting rods 1003 can swing to drive the top plate 1005 to descend. Conversely, the three groups of first connecting rods 1002 and second connecting rods 1003 can swing to drive the top plate 1005 to rise, so that the patient can get multi-directional, multi-angle and multi-height exercise. When the device is not in use, the three electric telescopic rods 1001 can be started to retract, so that the top plate 1005 is lowered to the lowest height. In this state, the first connecting rod 1002 and the second connecting rod 1003 are folded with each other for easy storage.
