Abstract

The utility model belongs to the technical field of electricity and magnetism, particularly a tool for magnetization and demagnetization, which comprises a shell body and a magnetic body. The inner portion of the shell body is provided with an upper slot and a lower slot. An upper magnetic body and a lower magnetic body are respectively arranged in the upper slot and the lower slot. A through hole is arranged between the upper slot and the lower slot. The two sides of the through hole are respectively provided with a left through slot and a right through slot. The portions of the outer portion of the shell body corresponding to the left through slot and the right through slot are respectively provided with a left boss and a right boss. The utility model has small size and convenient use and carrying with the purpose of one device with two functions. The utility model is an ideal tool used for magnetization and demagnetization.

Description

Magnetize, demagnetizer

The utility model belongs to electricity, magnetic technology field, the instrument of particularly a kind of magnetization, degaussing.

At present, have only magnetic screw driver on the market, magnetic weakened or disappeared long afterwards service time, when not required, can't demagnetize again, thereby give in the use of electrician's instrument and bring many inconveniences, though magnetizing apparatus or demagnetizer are arranged, use and carry equal inconvenience, all have single performance.

The purpose of this utility model is to overcome above-mentioned deficiency and to design an a kind of device dual-purpose, can magnetize, but again little, the low price of a kind of volume of demagnetization, easy to use and carry a kind ofly magnetize, demagnetizer.

The purpose of this utility model is achieved in that it is made up of housing and magnet, be provided with upper and lower two grooves in the housing, between upper and lower two grooves, be provided with through hole, the through hole both sides are respectively equipped with left and right groove, be respectively equipped with magnet in upper and lower two grooves in housing, outside housing, be respectively equipped with left and right convex with left and right groove corresponding section.

The utility model is owing to put into a housing to two magnets, and to the utlity model has a device dual-purpose so make, and volume is little, and use and carry all a kind ofly easily magnetize, demagnetizer.

Accompanying drawing is the utility model concrete structure and embodiment.

Fig. 1 is the utility model structural representation;

Fig. 2 is the A-A cutaway view of Fig. 1;

Fig. 3 is the utility model through hole 6 A-A cutaway view during for the hole, garden;

The A-A cutaway view that Fig. 4 is the utility model housing 1 when square;

Fig. 5 is the utility model housing 1 A-A cutaway view during for polygon.

Among the figure: 1-housing, the last groove of 2-, 3-upper magnet, groove under the 4-, 5-lower magnet, 6-through hole, 7-left side groove, the right groove of 8-, 9-left side convex, the right convex of 10-.

Below in conjunction with accompanying drawing the utility model is further elaborated:

By accompanying drawing as can be known, the utility model is by housing 1, on,

lower magnet

3,4 form, be provided with in the housing 1, following

groove

2,4, on,

lower magnet

3,4 be located at respectively in the housing 1 on, following groove 2, in 4, on in housing 1, following groove 2, be provided with through hole 6 between 4, both sides at through hole 6 are respectively equipped with a left side, right groove 7,8, outside housing 1 with a left side, right groove 7,8 corresponding sections are respectively equipped with a left side,

right convex

9,10, the cross section of housing 1 can be square, garden arc protrusion-shaped, trapezoidal or polygon, in the housing 1 on, following groove 2, through hole 6 between 4 can be square hole or hole, garden.

When using the utility model, in the in-line or the through hole 6 in cruciate flower shape screwdriver insertion the utility model with required usefulness, extract screwdriver then, screwdriver promptly is magnetized, also screwdriver can be inserted in the utility model and use, when screwing, can support like this, only need a hand just can to assemble at an easy rate or take off, when not needing to use magnetic, surperficial parallel the moving of instrument being pasted housing 1 gets final product degaussing, thereby it is dual-purpose to have reached a device, but can magnetize and the purpose of demagnetization.
