[0015] The present invention has the following beneficial effects: When the present invention is in use, after the device is installed on the patient to be used, the two shells are installed along the surface of the nut, and the screws are turned to fix the two shells to each other. At this time, in the end fixing component, after the shell is placed in the required position, the rope turning plate is rotated along the inner wall of the rope box. When the rope turning plate rotates, it will drive the pull rope to slide along the surface of the rope groove. When the pull rope runs, it will drive the pull sleeve plate to run along the surface of the fixed arc rod, and the pull sleeve plate will drive the elastic rope to run. When the elastic rope runs, it will shrink inward. When the elastic rope shrinks, it will slide along the surface of the telescopic pull rod, and drive the telescopic pull rod to telescope along the inner wall of the card plate. When the telescopic pull rod is telescopic, it will drive the push plate to run, and finally fix the push plate to the corresponding position of the patient, so that the top of the device is fixed to the patient's body part, preventing the top of the device from being unstable during use, affecting the use of the device, and even causing further injury to the patient.

[0016] When the present invention is in use, after the end of the device is fixed, the card block is inserted into the shell in the rotating component. When the patient uses it, the telescopic rotating rods on the surfaces of both ends of the sensor rotate along the surface of the steering base. When the telescopic rotating rods rotate, they will drive the arc telescopic rods to telescope. The arc telescopic rods and the telescopic rotating rods at both ends form a triangular stable structure to prevent the device from tilting during operation, affecting the use of the device. At the same time, when the telescopic rotating rod is away from the inner wall of the steering base, it rotates with the surfaces of the end base and the bottom base respectively. When the bottom base runs, it drives the control board to run, and the control board drives the shaft rod to rotate along the inner wall of the balance seat. Through the two-way rotation, the operation of the device is better protected, and excessive angular movement is avoided to avoid damage to the device and affect the patient's use.

[0017] When the present invention is in use, the bottom shell plate is slid along the inner wall of the bottom shell groove and the cross plate in the bottom stabilizing component, and the bottom shell plates of each group are installed corresponding to each other. After the bottom shell plates are installed, the slot plate is slid along the inner wall of the slide groove, and the slot plate is slid into the bottom shell groove to clamp the bottom shell plate and fix the bottom of the device. At the same time, when the device is running, the shaft rod will drive the heat dissipation fan to run, and the heat dissipation fan will perform heat dissipation treatment on the corresponding installation parts, so as to avoid the device from being damaged by sweat due to long-term use, which will affect the use of the device. At the same time, according to the patient's physical condition, the telescopic positioning rod operates to perform positioning. At the same time, the surface of the folding shell and the patient's body surface protect each other and prevent the device from being damaged by directional forces in other directions during operation. At the same time, when the bottom shell plate is fixed to the patient's body surface, the bottom telescopic plate will contact the patient's body surface to produce a telescopic effect. When the bottom telescopic plate is extended and retracted, it will drive the telescopic plate spring to operate. The telescopic plate spring reacts to the bottom telescopic plate through its own elastic force, so that the contact between the device and the patient's body surface is more stable, and the device can operate better.

[0018] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS
