AI Technical Summary
Technical Problem
Existing scanning tunneling microscopes suffer from severe wear of elastic components during coarse approximation and needle retraction processes in low-temperature, high-magnetic-field environments, leading to scanning accuracy issues.
Method used
A radially expandable contact part is provided on the inner wall of the fixed cylinder. Through the cooperation of the telescopic unit and the rotating cylinder, the friction between the elastic plate and the inner wall is reduced. A telescopic arc plate is used as the contact part to reduce wear.
Benefits of technology
This effectively reduces wear between the elastic sheet and the inner wall, improving scanning accuracy and extending the equipment's lifespan.

Abstract
本实用新型公开了扫描隧道显微镜技术领域的一种适用于低温强磁场的扫描隧道显微镜，包括框体、同轴设置在框体内壁的固定筒、滑动设置在固定筒内的滑动部以及用于带动滑动部升降的驱动单元，滑动部底部设置有压电扫描管及探针，其中，滑动部的侧表面设置有弹簧片，用于贴合在固定筒内壁，且固定筒上与弹簧片的贴合处设置有沿固定筒径向伸缩的伸缩单元，该扫描隧道显微镜通过在固定筒的内壁设置沿径向伸缩的接触部位，在滑动部进行升降时，也即进行粗逼近和退针的过程前，可以使弹簧片沿径向向外侧滑动，脱离与弹簧片的接触，进而降低弹性片与固定筒内壁的磨损程度，可以有效降低因弹性片与内壁磨损而带来的轴向精度问题。
