[0022] The connecting tube 5 is provided with a fixing ring 6, and the fixing ring 6 is provided with a limiting rod 7 for fixing it to the connecting tube 5. A first connecting plate 8 is fixed horizontally to the side wall of the fixing ring 6, and the movable end of the first connecting plate 8 is hinged to the second connecting plate 11 which swings back and forth with it, and the movable end of the second connecting plate 11 is hinged to the third connecting plate 10 which swings back and forth with it. The third connecting plate 10 is provided with a supporting assembly which rotates left and right with it, so that the supporting angle can be adjusted according to different examination parts of the patient, thereby providing better support when the patient is in different examination postures, making the examination easier.

[0023] like Figure 2 As shown, the support assembly includes a support plate 9, a third connecting plate 10 is provided with a through slot communicating with each other from top to bottom, the support plate 9 and the through slot are connected by a connecting ring 15, and the connecting ring 15 is freely rotatable left and right in the through slot, and a fixing belt 14 for fixing the patient's arm is provided on the support plate 9, which is convenient for fixing the patient's arm on the support plate 9 for support, and is convenient for the patient to valgus and internally rotate the arm when performing medial and lateral elbow joint examinations, and can also provide support when the arm is valgus and internally rotated, thereby improving the comfort of the patient during the examination;

[0024] The support plate 9 can be made of transparent material, so that the doctor can observe the arms of the patient when the arms are turned outward or inward.

[0025] The second connecting plate 11 is composed of the first fixed block 12 and the second fixed block 13. One end of the first fixed block 12 is hingedly connected to the first connecting plate 8 to swing forward and backward. One end of the second fixed block 13 is hingedly connected to the movable end of the second fixed block 13 to swing up and down. The other end of the second fixed block 13 is hingedly connected to the third connecting plate 10. The hinge connection portions of the first fixed block 12 and the second fixed block 13 are provided with an adjusting assembly to improve the supporting effect. The adjusting assembly can be switched between the posture of the patient during the examination of the rear elbow joint and the posture of the patient during the examination of the front elbow joint. Therefore, the patient can be flexibly changed during the examination of different parts without complicated operation steps to adjust the support, thereby improving the comfort and the work efficiency of the medical staff.

[0026] The first connecting plate 8 and the first fixed block 12 are hingedly connected by bolts. The second fixed block 13 and the third connecting plate 10 are hingedly connected by bolts. In use, a gasket can be added between the nut and the connecting plate to adjust the fit and make the support more stable.

[0027] Embodiment 4

[0028] In this embodiment, the connecting ring 15 is connected to the through groove through a connecting block. The two ends of the connecting block are fixedly provided with spherical bodies. The outer side wall of the connecting ring 15 is provided with a first sliding groove for the circumferential movement of the spherical body at one end of the connecting block. The inner side wall of the through groove is provided with a second sliding groove for the forward and backward sliding movement of the spherical body at the other end of the connecting block. The connecting ring 15 can be freely rotated left and right in the through groove while moving the support plate 9 forward and backward. Therefore, the flexibility is higher and the applicability is improved.

[0029] As shown in Figure 4 The adjusting assembly includes a connecting rod 16. The first fixed block 12 is provided with a first through hole that is open forward and backward. The second fixed block 13 is provided with a second through hole that is open forward and backward. The first through hole and the second through hole are connected and communicated. The connecting rod 16 is independently arranged in the first through hole and the second through hole. The connecting rod 16 located at the outer side is fixedly connected to the first fixed block 12 through a nut. A ratchet wheel 18 is sleeved on the connecting rod 16 between the nut and the first fixed block 12. The first fixed block 12 is provided with a pawl 17 matched with the ratchet wheel 18. The cooperation of the ratchet wheel 18 and the pawl 17 enables the second fixed block 13 to only swing upward. When the patient changes from the curved arm to the straight arm for examination, the second fixed block 13 is swung upward to form support for the arm. When the arm needs to be bent, the nut is loosened to move the connecting rod 16 forward and backward, so that the ratchet wheel 18 and the pawl 17 are disconnected. Therefore, the second fixed block 13 can swing downward. After adjustment to the horizontal state, the ratchet wheel 18 and the pawl 17 are reconnected.

[0030] The connecting rod 16 can also be replaced by a screw rod with a head, and the end without the head is connected with the ratchet 18, so that the nut at one end can be adjusted alone;

[0031] The first fixed block 12 and the second fixed block 13 can also be connected by a hinge with adjustable damping, and the support and swing are converted by adjusting the damping size during use.

[0032] The fixing belt 14 at the end of the patient's finger is in a wave structure as a whole, and the support plate 9 is provided with a plurality of passages for the fixing belt 14 to pass through, and a buckle is arranged at the bottom of the support plate 9 to fix the fixing belt 14, so as to fix the patient's finger alone, so that the support effect is better when the patient's arm is turned outward or inward, and adjustment is facilitated.

[0033] The fixing rod 4 is sleeved with a clamping plate 3 in threaded cooperation therewith, the diameter of the clamping plate 3 is consistent with that of the bottom plate 1, and the contact surfaces of the clamping plate 3 and the bottom plate 1 are both provided with anti-skid layers, so as to facilitate clamping and fixing by the clamping plate 3 and the bottom plate 1. During use, the connecting pipe 5 can be rotated to the lowest position first, and then clamped on the table plate or bed plate by the bottom plate 1 and the clamping plate 3 for use, so as to further improve the applicability and make the operation mode more flexible during use.

[0034] The working principle is that the positions of the connecting pipe 5 and the fixing ring 6 are first adjusted to a suitable support height, and then the patient's arm is fixed on the support plate 9 by the fixing belt 14. When the patient's arm wants to turn outward or inward, the connecting ring 15 will rotate in the through slot, and the patient's arm will always be supported at different angles by the fixing belt 14. When the patient's arm wants to stretch forward and backward or swing left and right, the first fixed block 12 and the third connecting plate 10 will swing, so as to support at different angles in the horizontal direction. When the patient's arm wants to be completely straightened, the second fixed block 13 will swing upward, and the position of the second fixed block 13 is fixed by the cooperation of the pawl 17 and the ratchet 18 after the arm is straightened, so that the third connecting plate 10 and the support plate 9 also support the patient's arm which is lifted after being straightened. When the arm needs to be curved, the position of the nut on the connecting rod 16 is adjusted first, then the connecting rod 16 is pulled to make the ratchet 18 and the pawl 17 disengage, so that the second fixed block 13 is horizontal, and then the connecting rod 16 and the ratchet 18 are reset.
