Technical Field
[0001] The present application relates to the technical field of desktop drilling rigs, and in particular to a locking mechanism for a lifting body of a desktop engineering drilling rig. Background Art
[0002] In the mechanical processing and manufacturing industries, bench drills are a common processing equipment, widely used in various process operations such as drilling, reaming, and tapping. Traditional bench drills are usually equipped with manual or automatic lifting mechanisms to achieve precise positioning and depth control of the drill bit on the workpiece.
[0003] Traditional desktop drilling rig lifting mechanisms usually use gears and toothed plates to achieve lifting. When performing certain tasks, the lifting body needs to be locked. In the existing technology, a common locking method is to press the studs that pass through the lifting body onto the lifting guide rail and achieve locking through friction. This method can easily cause irreversible damage to the surface of the lifting guide rail. At the same time, its locking strength is not high, and it is easy to slip when subjected to large gravity or external force.
