[0025] Through the above-mentioned arrangement, the cross-sectional dimensions of the second chute 10 are equal to those of the first chute 3. When the movable plate 9 is moved to the upper side to be flush with the mine measurement platform 1, the end faces of the first chute 3 and the second chute 10 coincide with each other. At this time, the mounting plate 6 can be slid to the inside of the second chute 10 through the slider 5 at the bottom, that is, it is now within the inner protection range of the shell cover 16.

[0026] In this method, a driving assembly is provided at the bottom of the mine measuring platform 1, and the driving assembly includes a limit column 11 and a threaded rod 13.

[0036] The working principle of the laser pointer slope determination device for mine surveying provided by the utility model is as follows:

[0037] When in use, the rotating plug cap 14 drives the threaded rod 13 to rotate, so that the threaded rod 13 drives the movable plate 9 to move downward, so that the shell cover 16 on the movable plate 9 exits the measurement field of view of the laser pointer 7, and prevents the shielding of the shell cover 16 from affecting the measurement work of the laser pointer 7. After the measurement work is completed, the rotating plug cap 14 drives the movable plate 9 to move upward, so that the upper side of the movable plate 9 is flush with the upper side of the mine measurement platform, and then the torsion block 81 is rotated to drive the friction chassis 83 at the bottom of the screw 82 to move upward, so that the friction chassis 83 is not aligned with the upper side of the mine measurement platform 1. Side contact, at this time move the mounting plate 6, move the mounting plate 6 and the laser pointer on the mounting plate 6 to the inner side of the shell cover 16 on the movable plate 9 through the first slide groove 3 and the second slide groove 10, twist the torsion block, drive the friction chassis 83 at the bottom of the screw 82 to conflict with the upper side of the movable plate 9, complete the positioning of the mounting plate 6 on the movable plate 9, then slide the door panel 17 to the front side of the shell cover 16, and insert the lateral positioning rod 18 into the limiting hole of the door panel 17. At this time, the laser pointer 7 is located within the protection range of the shell cover 16 to avoid being bumped during transportation.

The transmission assembly provided in the utility model can smoothly drive the movable plate 9 to move up and down on the mine measurement platform 1. A shell cover 16 is provided on the movable plate 9 to facilitate daily protection of the laser pointer 7 and avoid damage caused by bumps during daily transportation. When not in use, the threaded rod 13 can be driven to drive the movable plate 9 to move downward so that the shell cover 16 on it withdraws from the measurement field of view of the laser pointer 7. The operation is simple and quick, and the practicality is improved.
