[0036] like Figures 1 to 8 As shown;

[0037] In order to achieve convenience and reduce fatigue on the doctor's arm during treatment, this rheumatism ultrasonic treatment device includes an ultrasonic box 1 and a connecting line 13 fixedly connected to the inside of the ultrasonic box 1, one end of the connecting line 13 passes through the surface of the ultrasonic box 1, and the end of the connecting line 13 away from the ultrasonic box 1 is fixedly connected to the treatment head 12, and also includes a positioning component 2 arranged on the surface of the connecting line 13 and an adjusting component 3 arranged on the surface of the positioning component 2, and a locking component 4 is arranged on the surface of the positioning component 2;

[0038] The positioning assembly 2 includes a limiting shell 22 sleeved on the surface of the connecting line 13, the limiting shell 22 and the connecting line 13 are slidably connected, two positioning rings A21 are symmetrically arranged on the surface of the limiting shell 22, and a positioning groove 25 is opened on the adjacent side of the two positioning rings A21, and a gear ring A23 is arranged inside the positioning groove 25. The gear ring A23 is slidably connected to the positioning ring A21 through the positioning groove 25, and two gears A24 are symmetrically arranged on the surface of the limiting shell 22. The two gears A24 are meshed and connected with the corresponding gears A24. Two connecting blocks 27 are symmetrically arranged on the surfaces of the two positioning rings A21. The connecting blocks 27 are threadedly connected to the positioning ring A21 through bolts 214, and the adjacent sides of the two connecting blocks 27 on the same side are fixedly connected with toothed plates A28 The two tooth plates A28 are arranged alternately, each tooth plate A28 has a tooth groove 29 inside, each tooth groove 29 has a tooth plate B210 inside, the tooth plate B210 is meshed and connected with the tooth plate A28 through the tooth groove 29, the two tooth plates B210 are fixedly connected to each other through a fixed plate 212, a gear B211 is arranged between the two tooth plates A28, the gear B211 is meshed and connected with the two tooth plates A28, a positioning shaft A213 is fixedly connected to the surface of the gear B211, the end of the positioning shaft A213 away from the gear B211 passes through the fixed plate 212 and is slidably connected to the fixed plate 212, a spring A26 is arranged inside each positioning groove 25, and the two ends of the spring A26 are respectively fixedly connected to the gear ring A23 and the positioning ring A21.

[0039] In this embodiment: when rheumatism needs to be treated, the two positioning rings A21 are put on the legs so that the two positioning rings A21 are respectively located on both sides of the joint, so that the treatment head 12 can be directly opposite the joint position, thereby realizing the positioning of the treatment head 12 and avoiding the traditional treatment head 12 being limited by hand support during treatment. Then, the spacing between the two positioning rings A21 is adjusted according to the size of the joint, and force is applied to the fixing plate 212 to make the tooth plate B210 slide out from the inside of the tooth groove 29, and then the positioning shaft A213 is rotated to drive the gear B211 to rotate, and the gear B211 will apply force to the two tooth plates A28, indirectly causing the two positioning rings A21 to move in opposite directions until the two positioning rings A21 move to a comfortable position for the patient, and then force is applied to the fixing plate 212 to make the two tooth plates B210 insert into the inside of the tooth groove 29 to tighten the two tooth plates A28 The two positioning rings A21 are positioned by limiting the position of the two positioning rings A21.

When the gear ring B31 rotates, it will drive the gear C32 to rotate on the surface of the positioning ring A21. When the gear C32 rotates, the screw 33 extends toward the inside of the positioning ring A21, and the three clamping plates 35 are driven closer to each other. Because the legs have a certain curvature, when the clamping plates 35 are in contact with the legs, the positioning shaft B34 connected to the clamping plates 35 rotates inside the screw 33, thereby achieving the clamping of legs with different diameters.

[0043] Going further:

[0044] In an optional embodiment, a plurality of sponge strips 310 are evenly fixedly connected to the surface of each clamping plate 35 , and a plurality of air holes 311 are evenly opened inside each clamping plate 35 .

[0045] In this embodiment: In order to make the patient more comfortable when clamping, the sponge strip 310 will be softer and more comfortable when clamping due to the characteristics of its own material, while preventing the clamping plate 35 from being stuffy when clamping. The air hole 311 has a certain degree of air permeability, making the clamping more comfortable.

[0046] Going further:

[0047] In an optional embodiment, a plurality of fixed grooves are evenly provided inside the positioning ring A21, a tooth plate C36 is provided inside each of the fixed grooves, the tooth plate C36 is slidingly connected to the positioning ring A21 through the fixed groove, one end of the tooth plate C36 is fixedly connected to the clamping plate 35, a plurality of limiting holes 37 are evenly provided inside the positioning ring A21, a gear D38 is provided inside each of the limiting holes 37, the gear D38 is rotatably connected to the positioning ring A21 through the limiting shaft, the gear D38 and the tooth plate C36 are meshingly connected, an elastic volute 39 is provided inside the limiting hole 37, and the two ends of the elastic volute 39 are respectively fixedly connected to the positioning ring A21 and the limiting shaft.

[0048] In this embodiment: when the clamping plates 35 approach each other, the tooth plate C36 will slide inside the fixed groove. When the tooth plate C36 moves, it will drive the gear D38 to rotate inside the limiting hole 37, so that the elastic volute 39 is stretched and deformed, so that the clamping plate 35 is always in an arc shape for easy clamping.

[0049] Going further:

[0050] In an optional embodiment, the surface of the gear ring B31 is slidably connected to a positioning ring B41, the surface of the positioning ring A21 is evenly fixedly connected to a plurality of fixing rods 42, the surface of each fixing rod 42 is slidably connected to a limiting block 43, the surface of the positioning ring B41 is evenly provided with a plurality of limiting grooves 45, each limiting groove 45 is provided with a limiting plate 44 inside, the limiting plate 44 is slidably connected to the positioning ring B41 through the limiting groove 45, the surface of the fixing rod 42 is wrapped with a spring B46, the two ends of the spring B46 are respectively fixedly connected to the limiting block 43 and the fixing rod 42, the positioning ring B41 has an inclined surface on one side adjacent to the limiting block 43, and the positioning ring B41 and the limiting block 43 fit each other, and the surface of the positioning ring B41 is evenly fixedly connected to a plurality of rubber blocks 47.

[0051] In this embodiment: when it is necessary to rotate the gear ring B31, force is applied to the positioning ring B41 to make the positioning ring B41 slide on the surface of the gear ring B31 toward the direction of the fixed rod 42. Due to the matching of the shapes of the positioning ring B41 and the limit block 43, the positioning ring B41 squeezes the limit block 43, and the limit block 43 slides on the surface of the fixed rod 42, and the spring B46 is squeezed. When the limit block 43 slides on the surface of the fixed rod 42, the limit block 43 drives the limit plate 44 to slide out of the inside of the limit groove 45, thereby releasing the limit on the positioning ring B41. Then, force can be applied to the positioning ring B41 to make the positioning ring B41 drive the gear ring B31 to rotate, and the rubber block 47 will increase the friction with the positioning ring B41 to prevent it from slipping out.

[0052] The working principle and use process of the present invention:

[0053] When the device is in use, firstly, the two positioning rings A21 are put on the legs, so that the two positioning rings A21 are respectively located on both sides of the joint, so that the treatment head 12 can be directly opposite to the joint position, thereby realizing the positioning of the treatment head 12 and avoiding the traditional treatment head 12 being limited by hand support during treatment. Then, the spacing between the two positioning rings A21 is adjusted according to the size of the joint, and force is applied to the fixing plate 212 to make the tooth plate B210 slide out from the inside of the tooth groove 29, and then the positioning shaft A213 is rotated to drive the gear B211 to rotate, and the gear B211 will apply force to the two tooth plates A28, indirectly moving the two positioning rings A21 in opposite directions until the two positioning rings A21 move to a comfortable position for the patient, and then force is applied to the fixing plate 212 to make the two tooth plates B210 insert into the inside of the tooth groove 29 to limit the two tooth plates A28, thereby realizing the positioning of the two positioning rings A21.

[0054] When the distance between the two positioning rings A21 changes, the toothed ring A23 will slide inside the positioning groove 25 due to the limiting of the gear A24 and the elastic potential energy of the spring A26, so that the treatment head 12 is always located between the two positioning rings A21. During the treatment process, the treatment head 12 needs to be moved back and forth to expand the treatment area. When the treatment head 12 needs to be moved, force is applied to the limiting shell 22 to make the limiting shell 22 slide on the surface of the positioning ring A21, and the gear A24 will engage with the toothed ring A23 to make the gear A24 rotate on the surface of the limiting shell 22, so that the movement of the limiting shell 22 is smoother. The connecting line 13 can slide inside the limiting shell 22, and the position of the treatment head 12 can be adjusted according to the diameters of different legs, thereby achieving the limitation of the treatment head 12.

[0055] In order to make the patient more comfortable during clamping, the sponge strip 310 will be softer and more comfortable during clamping due to the characteristics of its own material, while preventing the clamping plate 35 from being stuffy during clamping. The air holes 311 have a certain degree of air permeability, making the clamping more comfortable.

[0056] When the clamping plates 35 are close to each other, the tooth plate C36 will slide inside the fixing groove. When the tooth plate C36 moves, it will drive the gear D38 to rotate inside the limiting hole 37, so that the elastic volute 39 is stretched and deformed, so that the clamping plate 35 is always in an arc shape for easy clamping.

[0057] When it is necessary to rotate the gear ring B31, force is applied to the positioning ring B41 to make it slide on the surface of the gear ring B31 toward the direction of the fixed rod 42. Due to the matching of the shapes of the positioning ring B41 and the limit block 43, the positioning ring B41 squeezes the limit block 43, and the limit block 43 slides on the surface of the fixed rod 42, and the spring B46 is squeezed. When the limit block 43 slides on the surface of the fixed rod 42, the limit block 43 drives the limit plate 44 to slide out of the inside of the limit groove 45, thereby releasing the limit on the positioning ring B41. Then, force can be applied to the positioning ring B41 to make it drive the gear ring B31 to rotate, and the rubber block 47 will increase the friction with the positioning ring B41 to prevent it from slipping out of the hand.
