As preferably, push rod is provided with scale mark.After push rod was inserted into sense channel compression arc spring, the inlet of the relative sense channel of scale mark on the push rod can produce a reading, thereby can draw the length of push rod insertion or the length of length of spring compressed.
Another kind of scheme: offer chute on the sidewall of sense channel, the width of chute is less than the diameter of sense channel, pushed section on the power arm is a plectane, the shape of plectane and sense channel shape match, be connected by connecting portion between plectane and the power arm, the width of connecting portion and the width of chute match.Push pedal on the power arm is a plectane, and the thickness of plectane is little, and plectane is connected with power arm by connecting portion, offers chute on the sense channel sidewall, after push pedal is inserted into sense channel, and the power arm rotation, connecting portion just slides in chute.
As preferably, semi-circular plate is provided with scale mark.Scale mark can draw the length of plectane process after the power arm rotation on semi-circular plate, also can draw the length of the compression of arc spring simultaneously.
As preferably, power source is a motor, and motor is fixed on the circle centre position of sense channel place circle, and the rotating shaft of motor connects power arm.Motor select for use a kind of can control torque the motor of output, the moment of torsion output of regulating motor according to different arc spring to be meeting the stressing conditions of arc spring reality, and the tangential direction that the position of motor has guaranteed the power arm rotation is subjected to force direction identical with arc spring; Power source also can adopt hydraulic way, such as hydraulic cylinder and various hydraulic control valve.
As preferably, power arm is provided with sensor, and sensor connects data output table.The situation of sensor arc spring compression, the final parameter that meets of on data output table, exporting detected arc spring.
The beneficial effects of the utility model are: the sense channel that matches by a shape with arc spring carries out spacing to arc spring, use the drive power source power arm again, power arm drives the pushed section arc spring that is placed in the sense channel is carried out the compressed detected load, by sensor output, so just can detect the load performance parameter that obtains arc spring at last.
