[0020] In the embodiment, the protection cover mechanism comprises a lifting plate 17, a rectangular vertical hole is formed in the mounting plate 16, and the four sides of the lifting plate 17 are in sliding contact with the four inner walls of the rectangular vertical hole.

[0021] In the embodiment, a connecting seat 18 is fixedly installed on the top of the lifting plate 17, and a protection cover 19 is fixedly installed on one side of the connecting seat 18.

[0022] In the embodiment, a limiting groove is formed in one side of the lifting plate 17, and a limiting block is fixedly installed on the inner wall of one side of the rectangular vertical hole, the outer side of the limiting block is in sliding contact with the inner wall of the limiting groove, and the limiting block and the limiting groove limit the sliding distance of the lifting plate 17.

[0023] In the embodiment, a locking bolt 20 is threadedly installed on one side of the mounting plate 16, and one end of the locking bolt 20 is in contact with one side of the lifting plate 17.

[0024] In the embodiment, the screw transmission mechanism comprises a screw rod 9 rotatably installed in the rectangular groove 7, the screw rod 9 is threadedly connected with the rectangular seat 8, one side of the horizontal plate 6 is fixedly installed with a motor 10, and an output shaft of the motor 10 is fixedly connected with one end of the screw rod 9.

[0025] In the embodiment, a sliding groove is formed in one side of the rectangular groove 7, and a sliding block is fixedly installed on the outer side of the rectangular seat 8, and the outer side of the sliding block is in sliding contact with the inner wall of the sliding groove.

[0026] In the embodiment, the top of the workbench 2 is fixedly installed with a placement table 3, a baffle 4 and a main control table 5.

[0027] Working principle: The electronic piano to be tested is placed on the placement table 3 of the workbench 2, and is positioned by abutting against the baffle 4 on one side.

[0028] The locking bolt 20 is loosened, the protection cover 19 is lifted upwards, and then the locking bolt 20 is tightened to fix it at a high position, so that the camera 13 and the laser device 14 are completely exposed and in a working state.

[0029] The laser device 14 is adjusted to a suitable height by the electric push rod 15, so that the line laser emitted by the laser device 14 can be clearly projected on the piano key plane.

[0030] The motor 10 is started by the main control table 5, the motor 10 drives the screw rod 9 to rotate, and drives the rectangular seat 8 to move stably and uniformly along the horizontal plate 6, so as to scan the entire piano key area.
