Description

Technical Field

[0001] This utility model relates to the field of drill bit protection technology, and in particular to a drill bit with a depth positioning capability. Background Technology

[0002] A drill bit is a tool used to drill holes in hard objects, typically wood, metal, concrete, and other materials. A drill bit usually consists of a metal shaft and a tip, which is often inlaid with carbide or diamonds to allow it to cut and penetrate hard materials. Drill bits are typically used in conjunction with equipment such as drill presses and electric drills.

[0003] However, in existing technologies, conventional drill bits typically use a hexagonal shape and are locked onto the electric drill. The drill then drives the drill bit to drill holes. However, in actual use, the high-speed rotation of the electric drill can easily cause the locking mechanism to disengage, resulting in the drill bit detaching from the drill and damaging it. This reduces its practicality in actual use. Therefore, we provide a drill bit with a depth-positioning feature. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of existing technologies and provide a drill bit with a depth-positionable function.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a drill bit with a depth-positionable design, comprising: a drilling mechanism, the drilling mechanism including a drill joint, a locking rod provided at the lower end of the drill joint, a fixing screw provided on the outer surface of the locking rod, a fixing disc provided between the six fixing screws, a nut provided on each of the six fixing screws, a spring provided on the lower side of the fixing disc, a buffer mechanism provided at the end of the spring away from the fixing disc, the buffer mechanism including a movable pad, a protective cylinder provided at the top of the movable pad, and a fixing mechanism provided at the lower end of the movable pad.

[0006] In a preferred embodiment, the fixing mechanism includes a snap-fit ​​cylinder, the top of which is provided with a fixing cylinder, and a buffer is provided in the fixing cylinder.

[0010] In a preferred embodiment, the top end of the protective cylinder is fixedly connected to the bottom end of the fixed plate by welding, and the movable pad is limited to the outer surface of the fixed screw and the buckle rod for lifting and adjustment.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows: This utility model fixes the bottom end of the drill bit to the top end of the snap-fit ​​rod, and then sets a fixing plate and a fixing screw on the outer surface of the snap-fit ​​rod.
