Description of the Invention: [Technical Field] The present invention relates to a muscle function measuring device, and more particularly to a measuring device for measuring the function of the palm muscle. [Prior Art] In the judgment of the upper limb limb disorder, whether the thumb function is normal or not has a great influence on the judgment result, and the classification of the limb disorder level is related to the degree of thumb damage. Therefore, the test of the thumb function is very important. Referring to Figure 1, when the thumb 10 moves left and right (in the direction indicated by the double arrow in the figure), it is mainly driven by three palm finger muscles located at the root of the plum finger, wherein the thumb 1〇 moves toward the palm of the hand ( As shown in the figure! (to the left), mainly driven by the "outside buckling short muscles", while the thumb moves toward the back of the hand (as shown in Figure i to the right), mainly by "stretching the longus muscles" and " Stretching the short and short muscles together. When any of the above three finger muscles is injured, it affects the left and right movement of the thumb. However, there is currently no instrument for testing the above-mentioned palmar muscles, such as the commonly used dynamometer, which needs to be gripped by the thumb 10 and the other four fingers to measure the hand grip, but the thumb 1G and the four fingers match. During the process of holding the 4 grip force meter, the movement of the thumb W is affected by multiple muscles (four). At this time, the muscles that move the thumb 1G move in addition to the above-mentioned abductor short muscles, long plum muscles and short muscles. It also includes other muscles, so the previous instruments cannot be single: It is measured whether the muscle functions of the three muscles that move the thumb 10 or so are normal - 〇 [Summary] Therefore, the object of the present invention is to provide a simple structure and use 5 200946082 Convenient and measurable measuring device for the muscle function of the palm of your hand. Thus, the finger muscle measuring device of the present invention comprises: a base, a pick-up piece, and a measuring unit. The base includes a grip for a hand held by a subject. The pick-up piece includes a fixing portion fixedly coupled to the base and a dialed portion for the thumb of the subject to be dialed. The measuring unit is connected to the picked-up piece' and measures the amount of stress generated by the thumb being deflected by the thumb. [Embodiment] The foregoing and other technical contents, features and effects of the present invention will be presented in the following detailed description of the preferred embodiments of the drawings. Before the present invention is described in detail, it is noted that in the following description, similar elements are denoted by the same reference numerals. Referring to Figures 2, 3 and 4, the first preferred embodiment of the muscle function measuring device of the present invention is for holding the hand of a subject and for measuring the normal function of the palm of the subject. Or, the metacarpophalangeal muscle is used to drive the left and right fingers to move left and right, and the metacarpophalangeal muscle of the embodiment refers to the abductor thumb muscle, the extension of the thumb muscle, or the short thumb muscle, wherein the thumb is toward the palm of the hand. The direction of movement is ^ driven by the abductor's buckling short muscles, and the movement of the thumb toward the back of the hand is driven by the extension of the longissimus dorsi - with the extension of the buckling short muscles. The palm finger muscle function measuring device of the present embodiment comprises: a base i, a pick-up piece 2 disposed on the base 1, and a measuring unit 3 connected to the picked-up piece 2. The base 1 includes a horizontal substrate 11, a cylindrical grip 12 extending upward from the substrate n, a support post 13 spaced behind the grip 12 and extending upward from the substrate a 200946082, and a horizontally disposed grip 12 A rectangular frame 14 at the top of the support column 13 and a pad joint 15 which is welded to the top surface of the frame 14 corresponding to the position of the support post 13 has a joint surface 151 facing the front side. The pick-up piece 2 of the present embodiment is made of a resilient metal elastic piece and has a rectangular plate shape extending in the front-rear direction. The pick-up piece 2 is spaced above the frame plate 14 and includes a rear end portion and The fixing portion 21 that is coupled to the φ surface 151 is fixedly welded, and the dial portion 22 is located at the front end and is slidable by the thumb of the subject. The measuring unit 3 comprises two strain gauges 31 and an oscilloscope 32 electrically connected to the stress gauges 31. Each of the stress gauges 31 includes a sensing member 311 'and a connecting line 312 electrically connecting the sensing member 311 and the oscilloscope 32. The sensing members 311 of the two stress gauges 31 are respectively disposed on the pick-up sheet. 2, the left and right sides of the surface 2, when the pick-up piece 2 is bent or deformed from the original position by the external force, the measuring unit 3 is used to measure the magnitude of the stress generated by the pick-up piece 2 due to the external force. The sensing component 311 detects the shape variable signal of the picked-up piece 2 and transmits it to the oscilloscope 32 via the connecting line 312. The oscillating device 32 displays a waveform for representing the magnitude of the stress, which can be converted from a large waveform. The magnitude of the stress of the pick-up piece 2, wherein the sensing member 311 adhered to the right side is used to detect the stress generated by the outward force of the pick-up piece 2, and the mold-like sensor 311 attached to the left side is used. In the detection of the received sheet 2, the stress generated by the external force is left. When the invention is used, the subject first holds the grip 12 by hand, and then rests against the right side surface of the pick-up piece 2 and Left-handed force, the pick-up piece 2 is bent and deformed by the external force applied by the 7 200946082 4, the imaginary line is shown), and the measuring unit 3 measures the magnitude of the stress of the pick-up piece 2 to measure the force of the thumb to the left. Since the pick-up piece 2 has elasticity, the pick-up piece 2 is toggled. After that, it will automatically reset to the state where it was not toggled. Then re-adjust the thumb position. Place the thumb against the left side surface of the paddle 2 and apply force to the right to measure the force of the thumb to the right. The magnitude of the stress is positively related to the external force applied to the paddle 2 by the thumb of the subject. Therefore, it is known by the magnitude of the stress that the palm muscle function for controlling the left and right movement of the thumb is normal, and whether the muscle exerting force is Sufficient. When the muscle function of the subject is normal and the thumb can be used to move the paddle 2, the waveform of the oscilloscope 32 will be clearly observed. When the muscle function of the subject is impaired and the force or force is insufficient, The waveform on the oscilloscope 32 will be weak or almost invisible. In summary, the stress of the paddle 2 is measured by the present invention to know whether the thumb of the subject can move left and right arbitrarily, due to the thumb. Left and right. The movement to the left is mainly controlled by the exoskeleton buckling muscle, the extension of the longus muscle, and the metacarpophalangeal muscles such as the buckling short muscles. Therefore, the present invention can test whether the muscle functions are 'normal.' 5, 6, the second preferred embodiment of the palm finger muscle function measuring device of the present invention also includes: a base 1, a pick-up piece 2 disposed on the base 1, and a connection to the dialed Measuring unit 3 of sheet 2.
