Magnetic woodworking pen

Abstract

This invention discloses a magnetic woodworking pen, belonging to the field of tool pen technology. It includes a pen cap and a woodworking pen; the pen cap has a hollow interior, with its bottom shaped to fit the pen tip; an iron ring is fixedly fitted onto the pen near the writing end; a magnet is fixedly installed at the bottom of the pen cap, and the iron ring and magnet magnetically engage to secure the pen inside the cap. The magnet is located at the bottom of the pen cap, and when the user uses it with one hand, force is applied to the end of the pen. A long lever arm is formed between the point of force application and the magnetic attraction point, significantly reducing the pushing force required to overcome the magnetic attraction, thus achieving effortless and convenient one-handed operation.

Claims

1. A magnetic woodworking pen, characterized in that it comprises: Pen cap (1), the upper part of the pen cap (1) is set with an opening (13) and the inside is a hollow tubular structure; writing piece (2), the writing piece (2) is placed inside the upper opening (13) of the pen cap (1); iron ring (3), fixedly sleeved on the writing piece (2), and the position of the iron ring (3) on the writing piece (2) is close to the writing end (21) of the writing piece (2); magnet (4), fixedly set inside the pen cap (1) near the bottom of the pen cap (1); wherein, the writing piece (2) is configured to be inserted into the pen cap (1) from the upper part of the pen cap (1) and the lower part of the writing piece (2) is wrapped by the pen cap (1), and the iron ring (3) and the magnet (4) are attracted to each other by magnetic attraction, so as to realize the separable fixation between the pen cap (1) and the writing piece (2).

2. The magnetic woodworking pen as described in claim 1, wherein, The pen cap (1) has a limiting step (11) near the bottom inside. The magnet (4) is inserted through the upper opening (13) of the pen cap (1) and abuts against the limiting step (11) to limit the axial position of the magnet (4) inside the pen cap (1).

3. The magnetic woodworking pen as described in claim 2, wherein, The pen cap (1) is also provided with a limiting ring (5) inside. The limiting ring (5) is located on the side of the magnet (4) away from the bottom of the pen cap (1) to prevent the magnet (4) from moving backward toward the opening (13) of the pen cap (1).

4. The magnetic woodworking pen as described in claim 3, wherein, The outer surface of the limiting ring (5) is provided with a protrusion (51), and the inner wall of the pen cap (1) is provided with a groove (12) that matches the protrusion (51). The limiting ring (5) is fixed in the pen cap (1) by being inserted into the groove (12) through the protrusion (51).

5. The magnetic woodworking pen as described in claim 4, wherein, The limiting ring (5) is an annular part, and its inner ring edge is provided with a chamfer (52).

6. The magnetic woodworking pen as described in claim 1, wherein, When the writing piece (2) is placed inside the pen cap (1) and the iron ring (3) and the magnet (4) are in a magnetic attraction state, there is a radial gap between the outer wall of the writing piece (2) and the inner wall of the pen cap (1).

7. The magnetic woodworking pen as described in claim 1, wherein, The outer wall of the pen cap (1) is provided with a hook (14).

8. The magnetic woodworking pen as described in claim 7, wherein, The inner surface of the hook (14) is provided with a number of barbs (141).
