4. In the process of calibrating the relevant parameters of the resiliometer (see fig. 21-22), the driving operation rod is rotated to enable the driving gear to drive the driving rack to act, so that the main sliding plate and the auxiliary sliding plate move to the right (at the moment, the fixed guide rail component is locked), at the moment, the right side of the flick rod is propped against the steel anvil after the previous flick unhooking, and the flick hammer moves relatively to the guide flange under the pushing action of the flick spring. Because the left notch and the right notch of the guide flange are embedded in the guide strip, the main sliding plate moves leftwards at the moment, the impact hammer is static relative to the main movable plate and has a downward movement amount, so that the highest position of the circumferential surface of the impact flange of the impact hammer is lower than the bending part of the scale, namely, the bending part is in a static state in the process of resetting the upper hook, the reset spring is gradually reset and lengthened from a compressed state, the unhooked connection part is contacted with the unhooked hook part and locked after being displaced to a certain distance (see figure 16), the upper hook resetting action is finished at the moment (before the upper hook is not reset, the impact hammer component is in a free state, and the length of the installation end of the impact tension spring seat and the installation end of the impact tension spring can be measured by a vernier caliper with specified precision, namely, the working length of the impact tension spring is measured); then, the driving gear is driven to drive the magnetic stripe to act through rotating the driving operation rod, the main sliding plate and the auxiliary sliding plate move rightwards, the impact spring is gradually stretched, the reset spring is gradually compressed, the stroke is displaced until the unhooking screw touches the unhooking impact part (an operation handle part of the locking part is screwed at the unhooking separation critical point, the distance between the impact surface of the impact rod and the impact surface of the impact hammer can be measured by a vernier caliper with specified precision, namely the impact length of the impact tension spring is measured), when the unhooking hook part is separated from the unhooking joint, the impact hammer moves rightwards under the elastic force of the impact tension spring, impacts the impact rod, when rebounding, the guide flange is positioned at the highest position of the guide strip, the rear side surface of the impact flange of the impact hammer contacts with the front end of the bending part, and the impact hammer drives the pointer component to displace by a certain distance in the rebounding process, namely the rebound quantity is measured.
