Hand tool magnetic switching structure

The present invention relates to a hand tool, and more particularly, to a hand tool having a magnetic attraction effect and capable of switching a magnetic state.

Press, in order to easily store hand tools, or to easily fix hand tools in the working environment, using a magnet to provide magnetic adsorption combined with the tool storage box or workplace tabletop has been widely cited in the industry; for example, Taiwan's new patent No. M342246 "Clamp with magnet" or Taiwan invention patent No. I265846 "Improvement of the magnetic structure of the handle of the screwdriver".

However, the aforementioned patent discloses a hand tool with continuous magnetic adsorption characteristics, which can certainly meet the above requirements; however, the application of hand tools to some workplaces with precision instruments may cause magnetic field interference with electronic components in the instrument. Affecting its performance; or, hand tools in the operating state, attracting unnecessary components and causing trouble. Therefore, switching the state of magnetic adsorption seems to be the solution to the aforementioned troubles.

The hand tools disclosed above are still inconvenient and need to be improved.

SUMMARY OF THE INVENTION A primary object of the present invention is to provide a magnetic switching structure for a hand tool that has a magnetic attraction effect and is capable of switching a magnetic state.

It is still another object of the present invention to provide a magnetic switching structure for a hand tool that utilizes the radial displacement of the effective magnetic region to achieve the effect of switching magnetic attraction.

It is still another object of the present invention to provide a magnetic switching structure for a hand tool that achieves low cost and easy operation with a simple structure.

In order to achieve the above object, the present invention provides a magnetic switching structure for a hand tool, comprising a body, at least one magnetic member, and an adjustment ring. The body has a central shaft having a grip portion at one end and at least one recess in the radial direction. The magnetic member is correspondingly disposed in the recess, and has a magnetic member having a magnetic field. The adjusting ring sleeves the handle portion and is angularly displaceable; the inner peripheral wall is recessed with at least one magnetic force switching portion to correspond to the recess; the magnetic switching portion includes a proximal portion and a distal portion; the proximal portion The wall thickness is greater than the wall thickness of the distal segment. When the adjustment ring is angularly displaced, the angular displacement of the distal segment is displaced to the recess such that the effective magnetic region of the magnetic member falls outside the handle portion. Conversely, if the proximal segment angle is displaced to the recess, the effective magnetic region of the magnetic member moves into the handle portion. Therefore, the radial movement of the effective magnetic region of the magnetic member enables the hand tool to achieve magnetic attraction switching.

Referring to the first and second figures, the present invention discloses a perspective view and an exploded view of a first preferred embodiment of a magnetic hand shifting structure of a hand tool; the magnetic switching structure of the hand tool includes: a body 10; At least one magnetic member 20 and an adjustment ring 30.

The body 10 has a central axis X having a handle portion 12 at one end and an operating portion 14 at the other end. The handle portion 12 is recessed with a ring groove 122, and at least one recess 124 is disposed in the radial direction. The ring groove 122 and the recess 124 communicate with each other while referring to FIG. The magnetic member 20 is disposed in the recess 124. The adjusting ring 30 sleeves the ring groove 122 of the handle portion 12 and is angularly displaceable.

The magnetic member 20 has a resilient member 22 and a magnetic member 24 sequentially embedded in the recess 124. Referring to FIG. 3B, the magnetic member 24 has a predetermined range of effective magnetic regions, and the magnetic member 24 can receive the magnetic member 24. The elastic member 22 is pushed against and can be radially displaced by retraction or outward movement. The inner peripheral wall 32 of the adjusting ring 30 can abut against the outer peripheral wall of the ring groove 122 of the handle portion 12 of the body 10; further, the adjusting ring 30 is recessed by the inner peripheral wall 32 by at least one magnetic force switching portion 34. The recess 124 should be formed, and the front end of the magnetic member 24 protrudes from the recess 124 to abut the magnetic switching portion. The number of the recesses 124, the magnetic member 20, and the number of the magnetic switching portions 34 are corresponding to each other. In the embodiment, the number of the recesses is 4.

The wall thickness of the magnetic switching portion 34 of the adjusting ring 30 is not a single wall thickness, and referring to the third drawing C, the magnetic switching structure of the hand tool of the present invention uses the wall thickness of the magnetic switching portion 34 to change. To adjust the radial displacement of the magnetic member 24, the effective magnetic region of the magnetic member 24 can be moved inside and outside the grip portion 12 of the hand tool. The magnetic switching portion 34 may include a proximal section 342, a distal section 344, a transition section 347 connecting the proximal section 342 and the distal section 344, and adjacent to the proximal section 342, respectively. Two limiting walls 348, 349 with the distal segment 344. The wall thickness of the proximal section 342 is greater than the wall thickness of the distal section 344, such that the proximal length 342 and the diameter D1 of the body central axis X are shorter than the distal section 344 and the body central axis X. The path length D2 is such that the range of movement of the magnetic member 24 is switched between the path length D1 and the path length D2. The transition section 347 has a plane 345 and a slope 346 adjacent to each other. The plane 345 of the transition section 347 is in contact with the proximal section 342, and the slope 346 of the transition section 347 is connected to the remote section 344. The adjusting ring 30 abuts the ring groove 122 of the grip portion 12 with the limiting walls 348 and 349 .

As shown in the third figure, when the proximal portion 342 of the magnetic switching portion 34 is angularly displaced and aligned to the recess 124 of the grip portion 12, the front end of the magnetic member 24 abuts the proximal portion 342, and the rear end presses the same. The elastic member 22 causes the elastic member 22 to accumulate an elastic energy. At this time, the effective magnetic region of the magnetic member 24 falls within the handle portion 12 of the hand tool, and the hand tool can be regarded as a demagnetized state; In the fourth figure, when the adjusting ring 30 is angularly displaced, the distal portion 344 of the magnetic switching portion 34 is angularly aligned and aligned to the recess 124 of the grip portion 12, and the magnetic member 24 is received by the elastic member 22. Pushing, the elastic energy is converted into the radial energy, so the magnetic member 24 is radially outward and can be partially moved into the distal segment 344. At this time, the effective magnetic region of the magnetic member 24 is tied to the hand tool. Outside the grip portion 12, the hand tool can be considered to be in a magnetic state. Therefore, the magnetic switching portion 34 is operated to angularly displace the proximal portion 342 or the distal portion 344 to the recess 124, so that the magnetic member 24 changes in radial displacement, thereby making the magnetic member 24 effective. The magnetic zone moves in a radial direction, and the hand tool not only has the characteristics of magnetic adsorption, but also has the effect of switching the magnetic state.

Referring to the fifth figure, when the hand tool of the present invention is in the magnetic state, the magnetic component 40 of the workplace can be adsorbed for easy access or storage; when there is demagnetization demand, the hand tool of the present invention only needs a slight angular displacement. Adjusting the ring 30 allows the magnetic member to be radially retracted.

In the hand tool of the present invention, the adjusting ring 30 and the handle portion 12 of the body 10 are selected from the influence of the magnetic member 24 to avoid magnetization and interfere with the magnetic member 24; Referring to the second and third figures, in the embodiment, the operating portion 14 is made of a metal material and is disposed on the handle portion 12, and the effective magnetic region of the magnetic member 24 is attached to the operating portion 14. In addition, it is also possible to prevent the operation portion 14 from being magnetized by the magnetic member 24 to interfere with each other or cause work inconvenience.

The above embodiments are merely illustrative of the invention and not to be limiting. The invention can achieve magnetic switching only by simple structure, without complicated design and parts, and has low cost effect on the manufacturing side; in addition, it only needs angular displacement of the adjusting ring to achieve magnetic switching, and the utility model has the advantages of simple operation. .

In view of the magnetic switching structure of the hand tool, the magnetic member has an effective magnetic region, so that the effective magnetic region of the magnetic member has a radial displacement, thereby switching the magnetic state, which can be solved by the invention. The purpose is to refer to the structure of the first-class items, which is progressive, and is in line with the requirements of invention patents.
