High-precision oil filling pen

Abstract

The invention provides a high-precision oil filling pen used for filling oil into shaft holes and drill holes of clocks in the manufacture and maintenance of the clocks. The high-precision oil fillingpen comprises a first pen container, a second pen container, a pen point, a refill and a compression spring, wherein the first pen container and the pen point are respectively installed on two ends of the second pen container. The compression spring is installed in the first pen container, and the pen point is filled with lubricating oil. The pen point is sequentially inserted into the first pencontainer, the second pen container, the compression spring and the pen point. The refill is pressed, so that the refill extends out from one end of the pen point, and the lubricating oil flows out from the pen point end along the refill. The components of the oil filling pen provided by the invention are stably installed and are not easy to loose, an oil storage tank has a large wall thickness and thus is not easy to be broken; and the service life is long. Due to the arrangement of a plurality of push rod parts and needle point parts with different outside diameters of the refill, the oil filling control of the oil filling pen is more accurate, the structure is smart and exquisite, the use is extremely convenient, and the high-precision oil filling pen provided by the invention has highpracticability and relatively strong promotion significance.

Description

technical field [0001] The invention relates to an oil filling pen, in particular to a high precision oil filling pen used for watch maintenance and manufacture. Background technique: [0002] Watch manufacturing and maintenance is a very meticulous work. When adding oil to the clock shaft eye and drill hole in watch manufacturing and maintenance, it is very important to control the amount of oil. The amount of oil should not be sloppy at all. degree played a crucial role. If the amount of oil is too much, the running resistance of the gear teeth will be increased; if the amount of oil is too small, the lubrication effect will not be achieved, resulting in a large travel time error. [0003] At present, oiling pens are usually used for oiling clocks and watches. However, most of the traditional oiling pens have defects such as rough processing, easy loosening of the needle tube, oil leakage, easy rupture of the oil tube, difficulty in controlling the amount of oil added, an...
