When in use:

when the eddy current dynamometer 1 is required to be used for measuring output torque, in order to avoid using over-torque, over-rotating speed and over-power, the invention uses the forcing mechanism 5 to make high decibel sound when the eddy current dynamometer 1 is powered on, so as to force a worker to close the forcing mechanism 5, and in the operation process of closing the forcing mechanism 5, the current rated rotating speed, rated torque and rated power of the eddy current dynamometer 1 are memorized again, and the worker is reminded to avoid using over-torque, over-rotating speed and over-power to cause damage to the eddy current dynamometer 1, and the specific operation steps are as follows:

because the USB male port 504 and the USB female port 108 are in plug fit under the ordinary extension state of the reset piece C503, when the electric eddy current dynamometer 1 is powered on, the buzzer 502 is also powered on through the plug fit of the USB male port 504 and the USB female port 108, so that high decibel sound is emitted (in the step, a worker mainly forgets to cut off the power supply of the forcing mechanism 5 when starting the electric eddy current dynamometer 1, and can perform the power supply cut-off operation of the forcing mechanism 5 before the electric eddy current dynamometer 1 is powered on);

firstly, a worker can rotate five groups of identification mechanisms 2 corresponding to the positions below three signboards 105 according to the rated rotation speed, the rated torque and the rated power of the current eddy current dynamometer 1, for example, the rated torque of the current eddy current dynamometer 1 is 1000, at this time, the worker can rotate the five groups of identification mechanisms 2 to enable the corresponding 1000 digital identifiers 203 in the five groups of identification mechanisms 2 to face to the right front, such as 01000, the opening positions of the inserting hole positions B204 in the five groups of identification mechanisms 2 correspond to the positions of the corresponding 1000 digital identifiers 203 at the beginning of design, so that after the rotation adjustment of the five groups of identification mechanisms 2 is completed according to the rated torque of the current eddy current dynamometer 1, the inserting hole positions B204 of the five groups of identification mechanisms 2 correspond to the inserting hole position a109, and therefore the smooth insertion of the subsequent extrusion columns 401 is facilitated;

secondly, when the worker regulates the identification mechanism 2 correctly according to the rated rotation speed, the rated torque and the rated power of the current eddy current dynamometer 1, the limited block 402 pushes the extrusion column 401 rightwards, so that the extrusion column 401 penetrates through the plug hole site A109 and the plug hole site B204 to extrude the shell 501, the USB male port 504 is separated from the USB female port 108, and the power supply of the forcing mechanism 5 is cut off;

step three, after the power supply of the forcing mechanism 5 is cut off, in order to ensure that the power supply is cut off for a long time, the limiting column 301 is inserted into the limiting jack 403 of the limiting block 402, so that the limiting block 402 is limited, and the forcing mechanism 5 is prevented from being powered on again under the resetting action of the resetting piece B405 and the resetting piece C503;

after the output torque measurement is completed, the limit column 301 is pulled upwards only by the top block 302, so that the limit column 301 is separated from the limit jack 403, at this time, under the action of the reset piece B405 and the reset piece C503, the extrusion column 401 is separated from the plug hole site B204 and the plug hole site a109 without the obstruction of the limit column 301, the USB male port 504 is inserted into the USB female port 108 again, and then the worker can rotate the mixing identification mechanism 2 to continuously play a role in memorizing the current 'rated rotating speed', 'rated torque', 'rated power' of the eddy current dynamometer 1 for the next use.
