Oil level gauge

The utility model provides an oil level gauge which comprises the following components: an oil level gauge handle, an oil level gauge body and a spherical guiding member, which are connected with one another, wherein the oil level gauge body comprises a connection part and an oil surface detection part. The oil surface detection part and the connection part of the oil level gauge body are formed integrally, wherein the cross section of the oil surface detection part is rectangular and is twisted for a first angle from the lower end of the connection part. The first angle is not equal with 0 DEG or 180 DEG. The oil level gauge has the following advantages: simple structure, easy pulling-out and easy insertion. Furthermore because the oil surface detection part is twisted for a certain angle from the lower end of the connecting part, so the liquid level height of the machine oil can be clearly kept on the surface of the oil surface detection part of the oil level gauge, which comprises a connecting edge with a
