DESCRIPTION OF THE INVENTION: TECHNICAL FIELD OF THE INVENTION The present invention relates to a device for measuring the activity of a knot. It is especially suitable for the test of the activity of the rehabilitation of patients. [Prior Art] Ten tools for clinical evaluation of joint mobility in limbs (4) _ 〇meter, the evaluator must follow standard test procedures (such as disease 2 and joint specific position, _ quantitative axis (four) and two The arm of the end must be aligned with the prescribed amount, and the singer must give a weight (〇verpressure) to evaluate the tissue sensation of the tissue. However, in the clinical implementation of scale assessment, often patients with weakness, poor control of movement, muscle tension, silk weight or body size is much larger than the evaluator, etc. often can not - people independently perform this assessment, if barely executed, may cause excessive error At the same time, the judgment of the nervous and strenuous hand on the terminal is prone to f mistakes, and the guidance of the data is recognized, and the clinical decision of the successive _. Therefore, if there is a digital protractor that automatically displays the data (appears like a watch), it is fixed to the distal end of the test joint limb, and the performer only needs to help the patient's Lai's more than the patient. This ^ can more easily give the weight evaluation terminal feeling at the end of the action, starting and ending the angle of 201002300 can directly read the value on the S-position protractor. In this way, the evaluator does not have to be busy supporting the patient's limbs _ _ still hiding the correct position of the fixed 4 New Zealand, and there will be no trouble to find the hand to give heavy pressure. Therefore, the digital angle display can make the clinical evaluation of limb joint mobility more accurate and correct. The correctness of the obtained data is guaranteed to facilitate the use of medical decisions. [Invention] An instrument for measuring the degree of activity of a joint includes: (a) a casing; (b) an instruction input device located in the casing a surface (c) a control device that accepts instructions from the input device; (d) an acceleration measuring device that outputs an acceleration analog signal to the control device and accepts a measurement start command from the control device; and (e) - a fastening device that connects the outer casing to the limb of the subject. The acceleration measuring device is an inertial sensor for detecting the closing activity. The command input device is a measurement start, stop and result button. The invention further comprises a display device or a voltage stabilizing circuit device, wherein the display device can be an LED ' with a voice reading function, and the voltage stabilizing circuit is used for a 3.3 volt voltage regulation. The fastening device is attached to the limb with a magic felt. 7 201002300 [Embodiment] Description of each device function: The design of the present invention is shown in FIG. 10, which is composed of a command wheeling device, a control device 30, an acceleration measuring device 40, a display device 5, and a voltage regulator. The circuit device 60 and a fastening device 7 are composed, and the realization diagram is as shown in Fig. 2. Each device is responsible for the following work: Display device: The device is composed of a four-segment seven-segment display, and its function is to display the joint angle size 'provided The immortal conducts an evaluation record. This device is changed to the device (5), and the amount is recorded in the voice mode. Command input device: This device consists of two buttons or other components in the form of switches. It is mainly responsible for receiving the control commands of the fairy. The three key phases of the device are the fine key 90, the start key 1 〇〇, the stop key, j 〇; the 〇ffeet key is the measurement zero setting, the start key measurement start setting, and the st〇p key is the measurement stop. set up. This command input device can also be controlled by voice control using a microphone. Acceleration measuring device: The device is composed of three mutually orthogonal accelerometers, which mainly use the two sensors to detect the gravitational acceleration of gravity, as the object to be tested 8 201002300 Figure 3 is the measuring principle Note that adding a/b' gives e = tan-i(a/b). The reference basis for setting the angle in space, such as the angle between the speed gauge and the gravity, is tane = control device: The device is composed of - microcomputer controller, its function is divided into three parts, 1) receiving control input device Control command, 2) according to the amount of triaxial acceleration change provided by the joint angle measuring device, perform the measurement of the activity to be measured _ activity angle, and 3) display the output of the control value display device to provide the manufacturer to read the joint movement angle Silk circumference. 4 is a flow chart of the action of the control device of the present invention. Regulator circuit device: It is used for 3.3 volt voltage regulation. Fastening device: The invention is fixed to the limb with magic bristles. Operation steps The proximal limb 120 (such as the arm), the closure 130, and the limb 140 to be tested (such as the forearm) remain stationary at the measurement starting point, as shown in Fig. 5: 1. Turn on the power of the present invention. Second, the invention is first attached to the limb to be tested. 2. Place the limb to be tested at the measurement starting position. 201002300 Four five seven eight, press the Of fset button to set the current joint angle position to zero degrees. Press the Start button to start (4). As the angle of the joint to be tested changes, the numerical display of the present invention shows a corresponding change in the degree of the chirp. When the limb to be tested is placed at the maximum joint movement angle, press the stop button, this
