[0041] The implementation principle of a construction site engineering quality detection device according to an embodiment of the present invention is as follows: when it is necessary to detect the wall surface, the motor 31 is started, the motor 31 drives the first slide 12 to move downward, the first slide 12 drives the laser rangefinder 13 to detect the flatness of the wall surface, and at the same time, the first slide 12 drives the adjustment scraper 23 to move to clean the dust and stains on the wall surface. When the laser rangefinder 13 detects that the wall surface is uneven, the laser rangefinder 13 sends a signal to the control switch, the control switch controls the battery to energize the electromagnet 61, and the iron sheet 62 drives the motor 31 to move, so that the first gear 311 is separated from the second gear 321, the first gear 311 is engaged with the sixth gear 331, the motor 31 drives the driving guide rod 33 to rotate, and the driving guide rod 33 drives the marking pen 54 to flip and engage with the wall. When the marking plate 53 contacts the abutting inclined surface, the abutting plate 57 pushes the marking plate 53 to slide, and the limit block 82 is inserted into the limit slot again to lock the marking plate 53; when the first slide 12 moves to the bottom, the locking block 43 locks the first slide 12, and the motor 31 is started to reverse. The motor 31 drives the adjusting scraper 23 to move upward. When the adjusting scraper 23 moves to the top of the laser rangefinder 13, the locking block 43 disengages from the locking slot, and the motor 31 drives the first slide 12 to move upward.

[0042] The above are all preferred embodiments of the present invention, and are not intended to limit the scope of protection of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the scope of protection of the present invention.
