[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] This embodiment provides a multifunctional automobile adjustment tool. One end of the top of a support frame 1 is fixedly connected to a seat 2. Leg support plates 3 are fixedly connected to both sides of the top of the support frame 1. A suspension column 4 is fixedly connected to the top of the support frame 1 away from the seat 2. An elastic strap 7 is fixedly connected to the inner wall of the leg support plate 3 located in the middle of a movable plate 6.

[0030] The inner wall of the leg placement plate 3 is provided with an arc-shaped groove, which fits the patient's legs better and improves the patient's comfort when using it.

[0031] Example 1

[0032] like Figures 1 to 3 As shown, this embodiment proposes an adjustable traction frame, wherein a fixing frame 11 is fixedly connected to one side of the support frame 1, and a square plate 10 is slidably inserted into the interior of the fixing frame 11, and the top of the square plate 10 is fixedly connected to the traction frame body 9, and the top of the fixing frame 11 is fixedly connected to the fixing plate 13, and a first motor 14 is installed on one side of the fixing plate 13, and the output end of the first motor 14 is fixedly connected to the rotating block 12;

[0033] By starting the first motor 14 on one side of the fixed plate 13, the output end of the first motor 14 drives the rotating block 12 to rotate. When one end of the rotating block 12 rotates upward, one end of the rotating block 12 rotates in the square plate 10, so that the square plate 10 moves upward in the fixed frame 11, thereby driving the slider 16 to move upward in the fixed frame 11. At this time, the square plate 10 moves upward to push the traction frame body 9 in the ring 8. When one end of the rotating block 12 rotates downward, the use positions of the square plate 10 and the traction frame body 9 in the reverse direction are lowered, and the tension spring 15 expands and contracts with the movement of the square plate 10.

[0034] A circular ring 8 is fixedly connected to one side of the support frame 1, and a traction frame body 9 is slidably inserted into the circular ring 8. The circular ring 8 limits the moving position of the traction frame body 9, making the traction frame body 9 more stable when moving up and down, reducing displacement after long-term use;

[0035] Tension springs 15 are fixedly connected to both sides of the bottom end of the square plate 10, and the bottom end of the tension spring 15 is fixed to one end of the fixing frame 11. Sliders 16 are fixedly connected to both sides of the square plate 10, and the slides 16 are slidably inserted into the fixing frame 11. The tension springs 15 are mainly used to withstand tension. When stretched, they will generate restoring force and provide resistance during stretching, making the square plate 10 more stable during use, providing support for the square plate 10, and reducing shaking during use.

[0036] One side of the rotating block 12 is rotatably inserted into the inner wall of the fixed plate 13, and the other end of the rotating block 12 is rotatably inserted into the square plate 10. The rotating block 12 is rotated and moved to different positions in the square plate 10, so that the use position of the square plate 10 and the slider 16 is moved up and down, which is convenient for adjustment according to different traction requirements.

[0037] Example 2

[0038] like Figure 4 and Figure 5 As shown, based on the same concept as the above embodiment, this embodiment further proposes: both sides of the bottom end of the support frame 1 are fixedly connected to the limit plates 21, and the limit plates 21 are rotatably inserted with a ball screw 18, the other end of the limit plate 21 is fixedly inserted with a round rod 20, the surfaces of the ball screw 18 and the round rod 20 are movably sleeved with a ball sleeve 19, and the top of the ball sleeve 19 is fixedly connected to the movable plate 6, one side of the ball screw 18 is installed with a second motor 17, and the side of the ball screw 18 that passes through the limit plate 21 is installed with the second motor 17;

[0039] After starting the two sets of second motors 17, the output end of the second motor 17 drives the ball screw 18 to rotate in the limit plate 21. When the second motor 17 drives the ball screw 18 to rotate clockwise, the ball screw 18 rotates clockwise and drives the ball sleeve 19 to move leftward in the square groove 5. The movement of the ball sleeve 19 drives the connecting plate 22 to move, and the connecting plate 22 drives another set of ball sleeves 19 to move on the surface of the round rod 20. Finally, the movement of the ball sleeve 19 drives the movable plate 6 to move, so that the position of the patient clamping is adjusted. When it is necessary to move to the right, the output end of the second motor 17 drives the ball screw 18 to move counterclockwise.

[0040] A square groove 5 is provided at the top of the support frame 1, and a ball sleeve 19 is movably inserted into the square groove 5. There are multiple sets of square grooves 5 and ball sleeves 19, and the multiple sets of ball sleeves 19 are arranged in a "T" shape, so that the ball sleeves 19 can move vertically to the left or right when moving, thereby maintaining a stable fixation on the patient's limbs;

[0041] Some ball sleeves 19 are sleeved on the surface of the ball screw 18 by means of a threaded rotation, and other ball sleeves 19 are movably sleeved on the surface of the round rod 20. Every two groups of ball sleeves 19 are fixed to each other by a connecting plate 22. The connecting plate 22 allows one group of ball sleeves 19 to drive the other group of ball sleeves 19 to move, so that the two groups of movable plates 6 can maintain a consistent moving position and prevent the ball sleeves 19 from rotating with the rotation of the ball screw 18.

[0042] Working principle: Place the whole device in a suitable position, use an external power supply to provide power source for the device, and the staff starts the work through the external remote control. The first motor 14 and the second motor 17 are stepping motors, which have relatively precise position control capabilities, can rotate forward and reverse, and also have a self-locking function;

[0043] During use, let the patient sit on the seat 2 and place the patient's legs on the two sets of leg placement boards 3. Fix the relative position of the thigh or calf according to the position where the patient needs traction, adjust the use position of the movable plate 6 by starting the second motor 17, and then fix the patient's legs by adjusting the two ends of the elastic strap 7. Subsequently, adjust the use height of the traction frame body 9 according to the use requirements, and finally wrap one end of the traction rope around and fix it on the traction frame body 9 and the suspension column 4, and fix the other end to the patient's affected part. After fixation, traction can be performed. Traction is an existing technology and will not be described here.

[0044] The above is the entire working principle of the utility model.

[0045] Finally, a few points should be explained: First, in the description of this application, it should be noted that, unless otherwise specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense, and may refer to mechanical or electrical connections, internal communication between two components, or direct connection. "Up," "down," "left," and "right" are only used to indicate relative positional relationships. When the absolute positions of the objects being described change, the relative positional relationships may also change.

[0046] Secondly: The drawings of the embodiments disclosed in this utility model only involve structures related to the embodiments disclosed in this utility model. Other structures can refer to common designs. In the absence of conflicts, the same embodiment and different embodiments of the utility model can be combined with each other.

[0047] Finally: The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
