Description

Provide hand tools with magnetic magnetizer

The present invention relates to a magnetizing device for hand tools, in particular to a magnetizing device that provides magnetism for hand tools.

Press, a screwdriver is a common hand tool in life. In order to facilitate the operation of the user, a magnet is usually added to the screwdriver, so that the screwdriver can absorb the screw and other coupling components.

For products such as PCB printed circuit boards, in order to be able to install different types of products, such as graphics cards, central processing units, fans and other equipment, hand tools need the assistance of magnets to attach smaller screws to the screwdriver. When using a screwdriver to lock the screw on the printed circuit board, the structure of the printed circuit board is quite precise. If a traditional screwdriver is used, it is easy to be interfered with by the handle. Therefore, sometimes the user will also hold the aforementioned magnetizer to assist. The screwdriver turns.

Since there are many sizes of screws on the printed circuit board, at least two types of screwdrivers must be prepared to perform the locking work. Therefore, some companies have developed the magnetizers shown in the first to third pictures. This type of magnetizer uses magnets to repel the same sex. , The principle of the attraction of opposite sexes, a body 11 is provided with two symmetrical grooves 12; these two grooves 12 have a movable distance, and a magnet 13 is assembled in each groove 12, of which, two magnets 13 Are opposite with the same polarity (as shown in the second picture), so that the two The magnet 13 is in the first position A1 with movable distance; when the screwdriver is placed, as shown in the third figure, the magnet 13 uses the magnetic attraction of the magnet 13 to move to the second position A2 and is attached to the screwdriver. , And magnetize the screwdriver.

Although the aforementioned design concept allows the magnet 13 to move and magnetize the screwdriver, in actual use, there is no big problem in the use of a screwdriver with the size of the combined hole of the body 11; but when the screwdriver has a larger specification Small, in use, because the magnet 13 is only attached to the surface of the screwdriver, the magnet will slip and spin when it is rotated by a magnetizer.

How to improve the lack of customary structure is a problem that the relevant industry actively overcomes.

The main purpose of the present invention is to provide a magnetizer that provides magnetism for hand tools. The magnetizer is reset so that the body can change the clamping distance with the diameter of the hand tool, so that the screw lock operation can be carried out smoothly.

The structure that can achieve the above-mentioned purpose includes: a body and two magnetic attraction units;

The aforementioned body includes a first housing, a second housing, and two connecting plates; the first housing and the second housing are arranged symmetrically, and the first housing and the second housing are respectively arranged at both ends There is a sliding groove, the sliding grooves of the first housing and the second housing are provided with a movable area along the direction of the connecting plate, and the center of the first housing and the second housing has a mounting groove for two The magnetic attraction unit is assembled; the two connecting plates are similar to an I-shaped structure, and the upper and lower ends of the two connecting plates are respectively inserted into the sliding grooves provided in the first housing and the second housing, by the connecting plates So that the first housing and the second housing are assembled to form the main body, and a coupling hole for accommodating a screwdriver is formed in the main body;

The two magnetic attraction units are respectively installed in the mounting groove, and the opposite faces of the two magnetic attraction units are of the same polarity; when the screwdriver is not assembled in the coupling hole, the magnetic poles of the two magnetic attraction units repel each other, allowing the first housing The body and the second housing are separated from each other by the movable area; when the screwdriver is assembled in the coupling hole, the two magnetic attraction units are adsorbed on the surface of the screwdriver, and the first housing faces the second housing through the movable area. Push in the direction of the housing, so that the body is tightly connected to the screwdriver.

In the embodiment of the present invention, the sliding groove of the first housing and the second housing is provided with a retaining wall, and an end cover is assembled opposite to the one end of the retaining wall, so that the two connecting plates and the second magnetic attraction The unit does not detach from the body.

In the embodiment of the present invention, the first housing and the second housing are further provided with meshable teeth.

In the embodiment of the present invention, the movable range of the coupling hole of the main body is between 4 and 7 mm.

Through the above description, the effects that the present invention can obtain are as follows:

1. The body of the present invention can change the suction distance according to the size of a screwdriver or a hand tool, so that the user can turn the body to perform the screw locking operation.

2. Since the body is tightly adsorbed on the surface of the screwdriver through the adsorption unit, it will not cause idling when rotating.

3. The main body is subject to the characteristics of variable distance, so the adsorption unit of the conventional structure will not interfere with the screw lock operation.
