[0040] As shown in Figure 1 , Figure 2 and Figure 5 , the telescopic mechanism comprises a plurality of telescopic rods 2, a connecting rod 201, a rotating rod 202 and a driving motor 203, the upper side of the mounting plate frame 1 is fixedly connected with a plurality of telescopic rods 2 which are symmetrical left and right, the telescopic ends of the telescopic rods 2 are connected with the adjacent connecting plates 105, the upper side of the mounting plate frame 1 is fixedly connected with the driving motor 203, the output shaft of the driving motor 203 is fixedly connected with the connecting rod 201, and the rotating rod 202 is rotatably connected between the connecting rod 201 and the adjacent connecting plate 105.

[0042] Example 2: on the basis of example 1, as shown in Figure 1 ,Figure 2 、 Figure 6 、 Figure 7 and Figure 8 As shown in FIGS. 1-4, the width adjusting mechanism further comprises a cover shell 3, a limiting pull rope 301, a torsion bar 302, a ruler block 303, and a clamping rod 304. The mounting plate frame 1 is fixedly connected with symmetrically arranged cover shells 3 on the left and right sides. The mounting plate frame 1 is rotatably connected with symmetrically arranged torsion bars 302 on the left and right sides. The torsion bar 302 penetrates the mounting plate frame 1 and extends into the adjacent cover shell 3. The outer end of the torsion bar 302 is fixedly connected with the ruler block 303. The inner end of the torsion bar 302 is wound with the limiting pull rope 301. The limiting pull rope 301 penetrates the cover shell 3 and is connected with the connecting plate 105 away from the cover shell 3. The mounting plate frame 1 is slidably connected with symmetrically arranged clamping rods 304 on the left and right sides. The outer end of the torsion bar 302 is provided with circumferentially equidistantly arranged clamping grooves. The clamping rod 304 is clamped into the adjacent clamping groove.

[0043] The arms of different patients have different thicknesses. The width adjusting mechanism can adjust the width of the connecting plate 105, so that the connecting plate 105 is more fitted to the patient's arm. The specific operation is as follows: the staff member pulls the clamping rod 304 upward, and the clamping rod 304 no longer clamps the torsion bar 302. At this time, the torsion bar 302 can be rotated to wind the limiting pull rope 301. When the torsion bar 302 winds the limiting pull rope 301, the limiting pull rope 301 also pulls the two ends of the connecting plate 105 inward. Since the middle part of the connecting plate 105 is fixed by the rotating rod 202, when the limiting pull rope 301 pulls the two ends of the connecting plate 105, the connecting plate 105 will be bent downward to reduce the width and be fitted to the patient's arm. The bending of the connecting plate 105 also drives the covering cloth 106 to bend, so that the covering cloth 106 is better fitted to the patient's arm. When the covering cloth 106 and the connecting plate 105 are adjusted, the staff member pushes the clamping rod 304 downward, and the clamping rod 304 is inserted into the torsion bar 302, thereby fixing the position of the torsion bar 302, so that the covering cloth 106 and the connecting plate 105 remain in the state of being fitted to the patient's arm. In this way, the width of the covering cloth 106 and the connecting plate 105 can be adjusted to fit different thicknesses of arms of patients.

[0044] As Figure 1 、 Figure 2 、 Figure 9 、 Figure 10 and Figure 11As shown, the temperature adjusting mechanism is capable of adjusting the temperature in the liquid guide pipe 104, and comprises a storage box 4, a contact plate 401, a top block 402, a top frame 403, a guide rod 404 and a pressing valve 405. The storage box 4 is fixedly connected to the rotating rod 202, and the contact plate 401 is fixedly connected in the rotating rod 202. The lower side of the contact plate 401 is in contact with the adjacent liquid guide pipe 104, and the contact plate 401 is a hollow structure with a narrow inside and a wide outside. The storage box 4 is in communication with the contact plate 401. The top block 402 is fixedly connected to the upper side of the outer end of the connecting rod 201. Two guide rods 404 are fixedly connected to the storage box 4, and the top frame 403 is slidingly connected between the two guide rods 404. The inner end of the top frame 403 is in extrusion fit with the top block 402. The pressing valve 405 is fixedly connected to the communication part of the storage box 4 and the contact plate 401, and the outer end of the top frame 403 is in extrusion fit with the pressing valve 405.

[0045] The temperature adjusting mechanism can adjust the temperature in the liquid guide pipe 104, so that the temperature in the liquid guide pipe 104 can be more obviously decreased. The specific operation is as follows: the staff puts ammonium chloride and other substances that can absorb heat in water into the storage box 4. When the cover cloth 106 is unfolded, the connecting rod 201 and the rotating rod 202 are rotated to be horizontally aligned, and the top block 402 also extrudes the top frame 403 to slide backward. The backward sliding of the top frame 403 extrudes the pressing valve 405 to open, and a part of the ammonium chloride in the storage box 4 falls into the contact plate 401, and then absorbs heat in the water in the contact plate 401. The contact plate 401 is in contact with the liquid guide pipe 104 and has a hollow structure with a narrow inside and a wide outside. Therefore, the cold produced by the heat absorbed by the ammonium chloride also increases from the inside to the outside, so that the temperature of the liquid guide pipe 104 decreases from the inside to the outside, and the cooling effect is more obvious. When the cover cloth 106 is folded, the connecting rod 201 and the rotating rod 202 are rotated to be folded, the top block 402 is separated from the top frame 403, and the pressing valve 405 is automatically closed. In this way, the temperature in the liquid guide pipe 104 can be gradually decreased from the inside to the outside, and the cooling effect is more obvious.

[0046] As Figure 1 , Figure 12 and Figure 13As shown, the height adjusting mechanism is capable of adjusting the height of the placing rack 102, and comprises an adjusting rod 5, a threaded rod 501, a top sleeve 502, a limiting rod 503 and a bevel gear 504. The adjusting rod 5 is rotatably connected to the lower part of the mounting rack 1, and the front part of the adjusting rod 5 is fixedly connected with a handle. The threaded rod 501 is rotatably connected to the lower part of the mounting rack 1, and the threaded rod 501 is threadedly connected with the top sleeve 502. The top sleeve 502 is pushed upward to move the placing rack 102 upward. The mounting rack 1 is fixedly connected with the left and right symmetrical limiting rods 503 at the lower side. The limiting rods 503 are slidably connected with the top sleeve 502. The rear part of the adjusting rod 5 and the lower part of the threaded rod 501 are fixedly connected with the bevel gears 504, and the two bevel gears 504 are meshed with each other.

[0047] The height adjusting mechanism is capable of adjusting the height of the placing rack 102, so that the placing rack 102 can better support the patient's arm to fix the device on the patient's arm. The specific operation is as follows: the staff drives the adjusting rod 5 to rotate through the handle, the adjusting rod 5 drives the threaded rod 501 to rotate through the two meshed bevel gears 504, the threaded rod 501 drives the top sleeve 502 to slide upward or downward, and the upward and downward sliding of the top sleeve 502 can extrude the placing rack 102, so as to adjust the height of the placing rack 102, so that the placing rack 102 can better support the patient's arm to fix the device on the patient's arm.

[0048] As shown in Figure 1 and Figure 14 The disinfection mechanism is capable of disinfecting the inside of the mounting rack 1, and comprises an ultraviolet lamp 6, a trigger switch 601 and a fixed block 602. The mounting rack 1 is fixedly connected with four equidistantly distributed fixed blocks 602 at the upper and lower sides, and the fixed blocks 602 are fixedly connected with the ultraviolet lamp 6. The upper side of the placing rack 102 is fixedly connected with the trigger switch 601, and the trigger switch 601 is electrically connected with the ultraviolet lamp 6.

[0049] The disinfection mechanism is capable of disinfecting the inside of the mounting rack 1. When the device is powered on, the water in the liquid storage tank 101 is heated, the ultraviolet lamp 6 operates to disinfect and sterilize the inner wall of the mounting rack 1, and cross infection is avoided. When the patient's arm contacts the trigger switch 601 on the placing rack 102, the ultraviolet lamp 6 can be automatically turned off. In this way, the inside of the mounting rack 1 can be automatically disinfected to avoid cross infection.

[0050] The above description is only the preferred embodiment of the present application, and it should be pointed out that those skilled in the art can make some improvements and refinements without departing from the principles of the present application, and these improvements and refinements should also be considered as the protection scope of the present application.
