[0067] With the above structure, the circular locking frame 71 is inserted into the circular locking block 73. When the circular locking hole 72 is aligned with the sliding cylinder 76, the sliding cylinder 76 is inserted into the circular locking hole 72 under the action of the return spring 77. At this time, the threaded adjusting rod 79 is rotated so that it can extend and retract within the inner wall of the threaded cylinder 78, thereby allowing the base 710 to contact the ground. At this time, the support block 713 can be inserted into the support frame 716, thereby providing support.

[0068] The overall working principle is as follows:

[0069] In use, the mounting plate 1 is fixed to the tunnel sidewall. At this time, the circular clamp 55 on the adjusting rod 52 is fixed to the circular clamp 53 on the connecting plate 65. The circular clamp 53 on the adjusting cylinder 51 is fixed to the circular clamp 55 on the rotating disk 43. The fourth threaded clamp 56 is inserted into the insertion hole 54. At this time, the nut 57 is fixed to the fourth threaded clamp 56. At this time, the adjusting rod 52 is inserted into the adjusting cylinder 51 so that the semi-circular strip 510 is inserted into the semi-circular groove 58. After the position is adjusted, the fifth threaded clamp 511 is rotated to fix it to the rectangular fixing groove 59.

[0070] Rotating the threaded rod 62 allows it to move the threaded hole block 64, which in turn moves the connecting plate 65, which in turn moves the mounting platform 2, thus allowing the height of the mounting platform 2 to be adjusted.

[0071] Rotate the fixed plate 41 so that it can rotate at one end of the auxiliary rod 42, thereby driving the mounting platform 2 to rotate. When it is rotated to the appropriate position, rotate the third threaded clamp 44 to fix it to the inner wall of the second annular fixing groove 45.

[0072] At this point, the laser emitter 326 is inserted into the fixed circular frame 324. The second threaded locking rod 325 is then rotated to fix the laser emitter 326. The pointer block 35 is then pushed, causing the first sliding rod 34 to slide along the inner wall of the annular groove 31. After sliding to the initial position, the first threaded locking rod 36 is rotated, allowing the first rubber block 37 to be fixed to the first annular fixing groove 33. Simultaneously, the pointer block 35 causes the second sliding rod 38 and the connecting block 39 to move synchronously, thereby moving the arc-shaped block 313 to the designated position, and the pointer... The angle between block 35 and connecting circular block 39 is the maximum allowable offset angle. At this time, according to the change of the center point, the controller 317 controls the drive motor 315 to start and stop, thereby driving the transmission rod 316 and U-shaped frame 320 to rotate, which in turn drives the laser emitter 326 to change position. When the angle offset is too large, the auxiliary ball 329 will move downward along the arc block 313, thereby driving the fixed circular block 322 and rotating rod 321 to rotate, which in turn drives the laser emitter 326 to rotate, so that the beam rotates to the top, thus indicating that the angle offset is too large.

[0073] When the circular locking frame 71 is inserted into the circular locking block 73, and the circular locking hole 72 is aligned with the sliding cylinder 76, the sliding cylinder 76 is inserted into the circular locking hole 72 under the action of the return spring 77. At this time, the threaded adjusting rod 79 is rotated so that it can extend and retract within the inner wall of the threaded cylinder 78, thereby allowing the base 710 to contact the ground. At this time, the support block 713 can be inserted into the support frame 716, thereby providing support.

[0074] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
