[0026] like Figure 1 , Figure 3 and Figure 4 As shown, the driving mechanism 4 includes two groups of rotating rods 405, two groups of fixing blocks 401 and a fastening block 402. The backs of the two groups of supporting mechanisms 7 are provided with grooves. The two groups of rotating rods 405 are respectively rotatably connected to the inside of the grooves of the two groups of supporting mechanisms 7. The outer surfaces of the two groups of rotating rods 405 are provided with circular saw teeth 406. One side of the left group of circular saw teeth 406 is installed on the side of the connecting block 3 away from the U-shaped block 101. The fastening block 402 is installed on the back of the left group of supporting mechanisms 7. A positioning groove is provided on the side of the fastening block 402 away from the U-shaped block 101. A fixing plate 403 is slidably connected inside the positioning groove of the fastening block 402. A through hole is provided at the bottom of the inner wall of the positioning groove of the fastening block 402. An electric telescopic rod 411 is provided inside the through hole of the fastening block 402. The output of the electric telescopic rod 411 The outlet end is installed on the lower surface of the fixing plate 403, and the side of the fixing plate 403 away from the U-shaped block 101 is installed on the side of a group of circular saw teeth 406 on the right side close to the U-shaped block 101. The two groups of fixing blocks 401 are respectively installed on the backs of the two groups of supporting mechanisms 7. Through holes are opened inside the two groups of fixing blocks 401, and the insides of the through holes of the two groups of fixing blocks 401 are slidably connected with fixing rods 408. The outer surfaces of the two groups of fixing rods 408 are provided with fixing rings 410. The sides of the two groups of fixing rings 410 away from the U-shaped block 101 are provided with return springs 404.

[0027] Specifically, when the subsequent positioning mechanism 1 is installed on the outer surface of the bedside on the patient's arm side, the two sets of handles 409 are pulled to drive the two sets of fixing rods 408 to pull the two sets of racks 407 out of the outer teeth of the two sets of circular saw teeth 406, and then the two sets of support mechanisms 7 are pushed to drive the two sets of support mechanisms 7 to rotate, and the positions of the two sets of support mechanisms 7 are adjusted and moved to the lower end of the patient's arm respectively, and then the two sets of handles 409 are released, so that the two sets of reset springs 404 push the two sets of fixing rings 410 to drive the two sets of fixing rods 408 and the two sets of racks 407 to reset, and the two sets of racks 407 are clamped in the outer teeth of the two sets of circular saw teeth 406, so that the two sets of support mechanisms 7 are positioned and installed at the lower end of the patient's arm to support the patient's arm, so that the subsequent two sets of support mechanisms 7 can be adjusted at multiple angles during use, thereby expanding the support range of the device during use, and thus improving the practicality of the device.
[0028] At the same time, when the subsequent right-side group of support mechanisms 7 are adjusted and moved, the electric telescopic rod 411 is started to drive the fixed plate 403 to move inside the positioning slot of the fastening block 402, so that the right-side group of support mechanisms 7 can synchronously adjust the up and down positions during the left and right adjustment and movement, and then the right-side group of support mechanisms 7 can move up and down, left and right during use, thereby expanding the support range of the right-side group of support mechanisms 7 during use, thereby improving the practicality of the device.
[0029] like Figure 1 As shown, the outer surfaces of the two groups of fixed rods 408 are slidably connected with positioning blocks 6, and the two groups of positioning blocks 6 are respectively installed on the back sides of the two groups of supporting mechanisms 7; specifically, the outer surfaces of one end of the two groups of fixed rods 408 close to the rack 407 are respectively slidably connected to the outer surfaces of the two groups of positioning blocks 6, so that the two groups of positioning blocks 6 limit the movement path of the two groups of fixed rods 408 close to the adjacent group of racks 407, thereby trying to avoid the subsequent deviation of one end of the two groups of fixed rods 408 close to the adjacent group of racks 407, which causes the two groups of fixed rods 408 to bend, thereby improving the service life of the two groups of fixed rods 408.
[0030] like Figure 1 As shown, the storage mechanism 5 includes a Velcro hook surface 501 and a Velcro fleece surface 502, and the Velcro hook surface 501 and the Velcro fleece surface 502 are respectively installed on the back sides of the two groups of support mechanisms 7; specifically, when the device is idle later, the front sides of the two groups of support mechanisms 7 are fitted together by flipping the right group of support mechanisms 7, and then the Velcro fleece surface 502 is pulled to adhere the Velcro fleece surface 502 to the side of the Velcro hook surface 501 away from the adjacent group of support mechanisms 7, so that the storage mechanism 5 limits the position of the two groups of support mechanisms 7 during the fitting and storage process, so that subsequent staff members do not need to disassemble the device when taking it, thereby facilitating the subsequent staff members to take the device and move it, thereby reducing the labor consumed by the subsequent staff members in carrying and moving the device, thereby improving the practicality of the device.
[0031] like Figure 2As shown, the support mechanism 7 includes a phenolic resin plate 701 and a cast aluminum plate 702. The phenolic resin plate 701 is provided with a groove inside, and the cast aluminum plate 702 is installed inside the groove of the phenolic resin plate 701; specifically, the phenolic resin plate 701 has good high elasticity and durability, so that the two groups of phenolic resin plates 701 are not easy to deform during use, and the two groups of phenolic resin plates 701 are not easy to be damaged during use, thereby improving the service life of the two groups of support mechanisms 7; the two groups of cast aluminum plates 702 are positioned inside the grooves of the two groups of phenolic resin plates 701, so that the two groups of cast aluminum plates 702 support the inside of the two groups of phenolic resin plates 701, thereby trying to avoid the two groups of phenolic resin plates 701 from bending when the upper end of the two groups of phenolic resin plates 701 carries too much weight, resulting in the two groups of support mechanisms 7 being unable to effectively support the patient's arms during use, thereby improving the practicality of the device.
[0032] In summary: by pulling the two sets of handles 409, the two sets of fixing rods 408 are driven to pull the two sets of racks 407 out of the outer teeth of the two sets of circular saw teeth 406, and then by pushing the two sets of support mechanisms 7, the two sets of support mechanisms 7 are driven to rotate, and the positions of the two sets of support mechanisms 7 are adjusted and moved to the lower end of the patient's arm respectively, and then by loosening the two sets of handles 409, the two sets of reset springs 404 push the two sets of fixing rings 410 to drive the two sets of fixing rods 408 and the two sets of racks 407 to reset, and the two sets of racks 407 are clamped inside the outer teeth of the two sets of circular saw teeth 406, so that the two sets of support mechanisms 7 are positioned and installed at the lower end of the patient's arm. The patient's arm is supported, so that the subsequent two groups of support mechanisms 7 can be adjusted at multiple angles during use, thereby expanding the support range of the device during use; by flipping the right group of support mechanisms 7, the front sides of the two groups of support mechanisms 7 are fitted together, and then the Velcro fur surface 502 is pulled to adhere the Velcro fur surface 502 to the side of the Velcro hook surface 501 away from the adjacent group of support mechanisms 7, so that the storage mechanism 5 limits the position of the two groups of support mechanisms 7 during the fitting and storage process, so that subsequent staff do not need to disassemble the device when taking it, thereby facilitating subsequent staff to take the device for movement.
