step one: firstly, the regulating block (54) is pulled outwards to separate a clamping block (59) positioned in the movable groove (55) and at the rear end of the connecting rod (58) from the clamping groove (56), then a limiting block (57) at the rear end of the regulating block (54) moves out of the inside of the limiting groove (592) when being pulled, at the moment, the regulating block (54) is moved to one side, the fixed block (52) abutted by the moving block (51) is not abutted at the moment, and the reverse elasticity of the first spring (53) is utilized to separate from the inside of the fixed hole (3), so that the tray main body (41) can be moved out of the inside of the placing groove (2);

step two: after the tray main body (41) is moved out of the placing groove (2), the adjusting block (54) is moved to the side of the adjusting groove (591), and the top block (47), the ejector rod (48) and the supporting plate (49) can be lifted up by utilizing the cooperation between the moving block (51) and the top block (47) during the movement, so that the inclination angle of the keyboard (491) is adjusted, and the keyboard is suitable for the use of workers by adjusting the inclination angle;

step three: the workbench body (8) slides in the sliding groove (10) from the inside of the accommodating groove (11) through the second sliding blocks (9) at the two sides of the workbench body (8), so that the workbench body (8) can be conveniently moved out of the accommodating groove (11), and then the workbench body (8) is placed on the workbench body (8) for trimming and maintenance when a PCB needing trimming is started to work;

step four: after the work is finished, the tray main body (41) is pushed to the inside of the placing groove (2), and the surface of the keyboard (491) can be cleaned by utilizing the cleaning roller (71) in the placing groove (2) in the pushing process.
