The invention provides a handheld tool for measuring the notch value of a point switch. The handheld tool can be used for measuring the notch value of an indication rod of a ZDJ9 type point switch, aZYJ7 type point switch and an SH6 type locker. The handheld tool comprises a base, a measuring scale, a pressing plate and a handheld handle. A clamping tongue on the base is hooked at the edge of thenotch of the indication rod or a locking rod; the measuring scale abuts against an inspection column through elastic force; and the current notch value is measured by reading scale values on the measuring scale and the pressing plate. The handheld tool for measuring the notch value of the point switch is easy and convenient to measure, simple and reliable in structure and capable of adapting to measurement of narrow spaces of various point switches.

    本发明提供了一种转辙机缺口值测量的手持工具,该手持工具可用于测量ZDJ9、ZYJ7型转辙机及SH6型锁闭器的表示杆缺口值。手持工具包括底座、量尺、压板和手持柄。底座上的卡舌钩在表示杆或锁闭杆的缺口边沿,量尺通过弹力顶在检查柱上,读取量尺与压板上的刻度值来测量当前缺口值。本发明所述的一种转辙机缺口值测量手持工具,已实现测量简便,结构简单可靠,可适应各类转辙机狭小空间的测量。
