The prompt
Create a mechanical assembly for a spring-loaded floor scraper blade holder. The assembly is mounted vertically under a steel frame. IMPORTANT MECHANICAL FUNCTION: The blade holder must move approximately 25 mm vertically up and down to follow uneven flooring, but it must absolutely NOT rotate left or right. Use THREE vertical rods: 1. One central M12 threaded rod. 2. Two smooth guide rods, 10 mm diameter, positioned symmetrically on the left and right of the M12 threaded rod. The M12 threaded rod is ONLY for adjusting spring preload. It is NOT the sliding guide. The two smooth guide rods are the actual vertical guides. Construction: - Upper mounting plate: 80 mm wide x 60 mm deep x 8 mm thick steel plate. - Central M12 threaded rod fixed vertically to the upper plate. - Two Ø10 mm smooth steel guide rods fixed vertically to the upper plate. - Distance between the two guide rods: 50 mm. - A movable steel blade-holder block slides vertically on the two Ø10 mm guide rods. - The movable block must contain two Ø10 mm sliding bushings. - The block must slide freely up and down approximately 25 mm. - The two guide rods prevent the block from rotating. - Put a compression spring around the central M12 threaded rod. - The spring sits between the upper mounting plate and the movable blade-holder block. - Add a large washer and adjustment nut above the spring on the M12 threaded rod. - Turning the M12 adjustment nut changes the spring preload. - Add mechanical stops so the movable block cannot fall off the guide rods. At the bottom of the movable block, create a replaceable steel blade clamp. The blade clamp holds a standard replaceable carpet/floor scraper blade. Use two horizontal M6 bolts to clamp the blade. Make the blade removable without removing the spring mechanism. The blade should point slightly forward in the pulling direction, approximately 20 degrees from vertical. Show the complete mechanism as a realistic mechanical assembly. IMPORTANT: Make every component clearly visible as a separate solid. Show a transparent/section view through the assembly so the spring, M12 threaded rod, two guide rods, sliding bushings, movable block and blade can all be seen. The critical requirement is: THE BLADE HOLDER SLIDES VERTICALLY ON TWO GUIDE RODS AND CANNOT ROTATE.
