This utility model discloses an auxiliary planting tool for cherry seedlings, belonging to the field of cherry seedling planting technology. Its key technical features include a fixed frame with a marking mechanism inside, a spacing mechanism on the rear side of the fixed frame, and a lifting rod on the top of the fixed frame. The spacing mechanism includes an indicator cone, a through hole, several graduated grooves, a spacing rod, and a limiting frame. The through hole is located inside the limiting frame, the top of the indicator cone is fixedly connected to the top of the inner wall of the through hole, the spacing rod is movably inserted into the limiting frame, and the graduated grooves are located on the rear side of the spacing rod. This invention solves the problem that existing methods for spacing cherry seedlings require prolonged bending and measuring with a ruler to mark the planting position on the ground, which is inconvenient, consumes a lot of physical strength, affects efficiency, and provides limited assistance for cherry seedling planting.

An aero-engine part marking device comprises a marking device body, a part moving tool, a guide rail and a workbench, and the marking device body is arranged on the workbench; the part moving tool and the workbench are arranged adjacently, and a guide rail is arranged in a matched mode and used for guiding the part moving tool to be close to the workbench. The guiding track limits the butt joint track of the part moving tool, and the part moving tool is in butt joint with the positioning part B of the workbench through the positioning part A, so that the working area of the marking device falls on a part fixed to a rotary disc of the part moving tool. The marking device comprises a controller, a marking device body, a marking supporting rack and a cantilever. A marking pen of the marking device body is arranged towards a rotary disc of the part moving tool. The marking supporting rack is fixed to the workbench, the cantilever is arranged on the marking supporting rack and can rotate relative to the marking supporting rack, the marking device is arranged on the cantilever, and the position of the marking device on the cantilever is adjustable.
