[0017] It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict.The utility model will be described in detail below with reference to the drawings and in combination with embodiments.

[0018] It should be noted that, unless otherwise specified, all technical and scientific terms used in the present application have the same meaning as generally understood by those skilled in the art to which the present application belongs.

[0019] In the utility model, unless otherwise stated, the direction such as "up, down" used is generally for the direction shown in the drawing, or for the vertical, perpendicular or gravity direction;Similarly, for the convenience of understanding and description, "left, right" is generally for the left and right shown in the drawing;"Inner, outer" refers to the inner and outer of the contour of each component itself, but the above direction words are not used to limit the utility model.

[0020] Please refer to Figs. 1-3 A kind of steel head of while drilling inclinometer, including pulse steel head 1, push rod 2 and end bolt 3 are arranged on the pulse steel head 1, the push rod 2 and end bolt 3 are connected, mud hole 4 is arranged on the end bolt 3, the mud hole 4 is straight hole, the push rod 2 is set as upper end is thicker than lower end, installation groove 5 is arranged on the upper end of the push rod 2, and sealing ring is arranged on installation groove 5.

[0021] In the embodiment, the installation groove 5 is provided with multiple.

[0022] In the embodiment, the sealing ring is provided with a plurality of mounting grooves 5.

[0023] In the embodiment, the mud holes 4 are provided with two, and are respectively arranged on both sides of the end bolt 3.

[0024] The mud hole 4 on the end bolt 3 is changed from the original angled hole to a straight hole, which is not easy to cause the sand in the mud to deposit; the structure of the end of the push rod 2 is changed from the original straight rod to a structure with a thick upper end and a thin lower end, and a sealing ring is additionally arranged on the mounting groove 5 of the thick end to improve the influence of the mud and the fine sand in the mud on the sealing during movement. After the improvement, the installation of the sealing ring is also facilitated, the sealing ring seat part is omitted, and the machining of the structural parts is reduced.
