[0002] The wireless inclinometer while drilling is an earth exploration instrument used in the field of mining engineering technology. It can measure the trajectory and azimuth of the borehole, as well as the inclination angle of the drill bit and other information. This instrument has been widely used in the exploration and development of mining, oil, natural gas and other industries. However, the wireless inclinometer while drilling itself has great defects. It is easy to lose the key, resulting in no signal of the instrument, and there will be hidden dangers. Therefore, it is necessary to prevent the wireless inclinometer from falling off.

[0003] A Chinese patent discloses an anti-dropout device for a wireless while-drilling inclinometer (Announcement No. CN220302119U). The patented technology has a reasonable and compact structure and is easy to use.

Although this patent can achieve the purpose of preventing the wireless while drilling inclinometer from falling off, it can be seen from the drawings of this patent that this patent uses an anti-falling claw to achieve the purpose of preventing falling off, but this method requires the claw to be opened and contracted when in use, which affects its anti-falling efficiency and the structure is also relatively complicated.
