In the daily production process, because round wire spiral springs of standard components such as ball jackscrews and sliding block positioners are smaller, after a period of stretching and compressing, the springs are easy to fatigue, and the ball or boss block cannot be pushed out or cannot be pushed out to be high enough, so that the function of positioning the sliding block stroke cannot be achieved. Thus, the slider positioning structure often requires replacement of the spring (see fig. 1-4).

However, existing standard components with ball head jackscrew positioning or slider positioning are seals, and it is not desirable to replace the spring, if it is necessary to replace the spring, the standard component needs to be replaced again. Because the bulb jackscrew location or slider locator is the standard component commonly used, the use amount is big, and the change volume is great, changes whole standard component because of spring fatigue and has the wasting of resources condition, has increased manufacturing cost.
