TECHNICAL FIELD OF THE INVENTION The present invention relates to a muscle strength meter, and more particularly to a muscle strength meter that can display an instantaneous speed state. [Prior Art] The muscle strength meter measures the muscle strength of a person's limb to provide a reference for athletes with muscle strain or muscle strength. In general, the hand-held muscle φ force meter is in contact with the subject's limbs and exerts force on the dynamometer to obtain the muscle strength of the limb. However, the measurement of the muscle strength of the limb is dynamic, and the limb system is an irregular surface, so that the state of contact between the limb and the dynamometer cannot be reliably grasped. As a result, the muscle strength measured by the dynamometer may lack accuracy and cannot be used by the user. In addition, when measuring with a hand-held dynamometer, it is necessary to follow the standard operating specifications and repeatedly perform muscle strength measurements in order to reduce the human error during the test to evaluate the muscle performance. However, the subject is often unclear about the immediate state of the operation, and it is often necessary to perform multiple invalid tests to complete an effective test. Therefore, the number of tests and the time of testing have increased relatively. Hey.

The controller outputs, for example, a pulse ▲ to indicate the magnitude of the instantaneous change amount 0. When the pulse signal is a positive voltage, indicating that the instantaneous change amount 4 is greater than zero, at least one of the plurality of light-emitting diodes 152 correspondingly generates a light signal or a changed state (blinking or discoloration, etc.). When the pulse signal is a negative voltage, it means that the instantaneous change amount must be less than zero, and at least one of the plurality of material diodes 152 correspondingly generates another light signal or changed state (? or discoloration, etc.). When the controller does not generate a pulse signal, f does not instantaneously change = the amount 0 is equal to zero, and at least one of the plurality of light-emitting diodes 152 maintains the current state. Therefore, the user can instantly know the current speed state based on the LED 152 = lamp number change. Further, the number of light-emitting diodes is not limited to a plurality. In the implementation of the shot, when the light is two poles! For example, the current speed can be expressed by the color change of the light. 2. The flute, for example, the red light indicates that the first light blue indicates the second light, and the green nine indicates the third light. - In another embodiment, the speed indicator A 150 is, for example, an audio finger = 2 using the frequency of the octave, the magnitude of the timbre, or the tempo of the timbre. The sound indicating unit is, for example, a speaker. For example, when the instantaneous amount of change is zero, the sound is fingered.

The speed indicating unit 150' is, for example, a display panel. The display panel has an image interface 154 for displaying the light level to indicate the current speed state. In the second figure, when the instantaneous change amount 0 is zero, the image interface 154 displays the first light number Βι, and the state in which the display is not visible is the iso-velocity motion. When the instantaneous change amount 0 is greater than zero, the I side 154 shows no second light number B2, indicating that the current state is the acceleration motion. When the instantaneous change amount 0 is less than zero, the image interface 154 displays the second light number B3 indicating that the current state is the deceleration motion. Therefore, the user can instantly know the current speed state based on the change of the light number of the speed indicating unit 15〇. In addition, the display panel further has a muscle strength value display area 156, which can display a muscle strength value according to the muscle force sensing signal VMS. The mode of operation of the muscle force sensing unit 120 will be described below. Referring to the figure, the muscle force sensing unit 120 includes a load cell 12 and a timer 126. The street weight element 121 is disposed in the body 11 〇. The sensing plate 124 is spaced apart from the load cell 121 by a distance, and the sensing plate 124 has a sensing surface 124a. The timer 126 is used to provide a plurality of measurement periods for the processor 14 to calculate the amount of change in speed per unit time. In the present embodiment, the timer 126 interrupts the timing every other measurement period, for example, when the user starts to measure the muscle strength using the muscle strength meter 100 to provide a measurement period. In general, the time to measure muscle strength by muscle strength is about 3 to 4 seconds. During the measurement of muscle strength, multiple isokinetic muscle strength tests were repeated ' until the muscle strength test was completed.

The insulating pad 123 is for contacting the object to be tested 10 such that the subject 10 contacts the sensing surface 124a via the insulating pad 123. The washer 128 is disposed between the sensing plate 124 and the load cell 121, and the sensing plate 124 is force-bonded to the load cell 121 to measure the muscle force. Next, reference is made to Figures 1 and 4, wherein Figure 4 depicts a measurement of the angular displacement in accordance with an embodiment. The speed sensing element 13 is, for example, a gyroscope or an accelerometer. The function of the gyroscope or accelerometer is to measure the angular displacement, angular velocity or angular acceleration when the subject 10 is oscillating, and store the measured result in the dynamometer 1 , for calculating the instantaneous variation 0 . The angular velocity, that is, the amount of change in angular displacement versus time, is usually expressed as an angular velocity. Angular acceleration produces the amount of angular velocity versus time. In Fig. 4, when the change 1 of the angular displacement is constant, it means that the angular velocity is not constant. If the slope L is expressed as the angular velocity, the larger the slope L is, the larger the angular velocity is; the smaller the slope L is, the smaller the angular velocity is. When the angular displacement versus time is linear, it means that the angular velocity is constant and the angular acceleration is zero, which is a constant velocity motion. Therefore, in the present embodiment, the angular velocity measured by the gyroscope or the angular acceleration measured by the acceleration gauge can be used to estimate the angular change when the subject 10 performs the rotational motion within a specific time period to calculate the instantaneous variation amount 0 of the angular velocity. The muscle strength meter disclosed in the above embodiment of the present invention uses the speed indicating unit to instantly display the speed state so that the subject can know whether the speed set by the operating specification is met during the test. In addition, the subject can immediately adjust the current speed according to the light and dark changes of the displayed light, the frequency of the sound, the amplitude or the color change, to avoid invalid test results. Therefore, the testee does not need to perform multiple invalid tests to complete a 201225921. 1 wooz^r/\ effective test, which improves the test validity and shortens the test time. In summary, although the invention has been disclosed above by way of example, it is not intended to limit the invention. A person skilled in the art can make various changes and modifications without departing from the spirit and scope of the invention. Therefore, the scope of the invention is defined by the scope of the appended claims.
