Abstract
The invention discloses a drilling positioning support which comprises a casing, wherein the bottom surface of the casing is fixedly connected with the top surface of an annular magnetic base, a circle of annular convex blocks is arranged on the top surface of the magnetic base in the casing, a positioning sleeve is sleeved on the inner wall of the casing, the positioning sleeve drives a spring to move vertically by being attached to the inner wall of the casing through the spring connected with the bottom end of the positioning sleeve, the top end of the spring is clamped in a circle of grooves disposed at the bottom end of the positioning sleeve, and the bottom end of the spring is clamped in grooves formed between the convex blocks and the casing. Therefore, the drilling positioning support is accurate in positioning and ensures that drill bits are vertically hit into metal parts when the positioning support is used for drilling of the metal parts.
Description
Technical field
The present invention relates to the electric drill technical field of tools, particularly relate to a kind of boring locating support.
Background technology
Electric drill is widely used in industrial production and daily life, particularly when commercial Application, when some metalworks are holed, tends to because the location is inaccurate electric drill is squeezed into according to the precalculated position influence boring effect.
Summary of the invention
The technical problem that the present invention mainly solves provides a kind of boring locating support, can accurately locate when metalwork is holed, and the assurance drill bit is vertically squeezed into metalwork.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: a kind of boring locating support is provided, comprise shell, fixedly connected with the end face of an annular magnet base in described shell bottom surface, magnetic bases end face in the described shell is provided with a circle annular lug, described outer casing inner wall is with a positioning sleeve, described positioning sleeve drives it by a spring that is connected with its bottom and is adjacent to outer casing inner wall and moves up and down, described spring top is stuck in the circle groove of positioning sleeve bottom, and described spring bottom is stuck in the groove that forms between projection and the shell.
In a preferred embodiment of the present invention, described positioning sleeve is inverted cone, and its bottom dead center position is provided with the opening that passes through for drill bit.
In a preferred embodiment of the present invention, described shell is hollow cylinder.
The invention has the beneficial effects as follows: can accurately locate when metalwork is holed, the assurance drill bit is vertically squeezed into metalwork.
