一种千分尺固定装置
摘要：
本实用新型公开了一种千分尺固定装置，以解决目前用千分尺测量试样原始横截面时操作不方便、效率低的问题。它主要由底座、半环形滑动槽、圆柱形滑块、拧紧手柄组成，半环形滑动槽固定在底座上，圆柱形滑块可以在半环形滑动槽中转动；拧紧手柄穿过半环形滑动槽插入圆柱形滑块的螺孔中，将圆柱形滑块和半环形滑动槽紧固在一起；在圆柱形滑块中部开有一个缺口，可将千分尺的握柄插入该缺口中；在圆柱形滑块上装配有定位螺钉，用于固定千分尺的握柄，以匹配不同规格型号的千分尺。使用本装置操作方便，测量的准确性和工作效率都得到提高。
摘要（英）：

The utility model discloses a micrometer fixing device, which solves the problems of inconvenient operation and low efficiency when a conventional micrometer is used for measuring the original cross section of a sample. The device is mainly composed of a base, a semi-ring shaped chute, a cylindrical slide block and a tightening hand shank, wherein the semi-ring shaped chute is fixed on the base, and the cylindrical slide block can rotate in the semi-ring shaped chute; the tightening hand shank passes through the semi-ring shaped chute and is inserted into the screw hole of the cylindrical slide block, and the cylindrical slide block and the semi-ring shaped chute are fastened together; a notch is formed at the middle part of the cylindrical slide block, and the handle of the micrometer is inserted into the notch; and a fixing screw is assembled on the cylindrical slide block and used for fixing the handle of the micrometer so as to be matched with micrometers with different specifications and models. The use and the operation of the device are convenient, and the measuring accuracy and the work efficiency are improved.
