Background

The screwdriver bit is a common tool for dismounting screws, has various types, is not used independently due to small volume, and is matched with a screwdriver bit handle, an electric screwdriver and the like. In the prior art, the insertion and the extraction between the screwdriver head and the handle or the electric screwdriver are directly pinched by fingers to complete the replacement, and a plurality of problems exist in the use, such as: after the screwdriver bit is inserted into the sleeve at the top end of the handle, because the exposed part of the screwdriver bit top end (between the screwdriver bit top end and the sleeve) is small, sometimes fingers can not be pinched by slip, and often put in the screwdriver bit and are difficult to take out, if the screwdriver bit is subjected to long-time construction operation, the screwdriver bit top end can also generate heat and expand, the screwdriver bit can not be taken out in the sleeve of the handle for a long time, and the construction period is very delayed; moreover, the existing screwdriver head handle or the sleeve at the top end of the electric screwdriver does not have any fixing device, and the screwdriver head is easy to loosen and fall off after being inserted, so that safety accidents are caused.

Disclosure of Invention

The utility model aims at providing a novel structure, easy operation, can appurtenance criticize first quick detach magnetic head of installation use.

The utility model discloses a following technical scheme realizes: a quick-release magnetic head is characterized by comprising a shell base body provided with a hollow cavity, wherein the front end of the shell base body is a batch head mounting hole, a magnet is arranged in the cavity at the rear end of the shell base body, the rear end of the magnet is fixedly connected with the shell base body through a magnet fixing body, a magnetic isolation ring is arranged at the front end of the magnet, the magnetic isolation ring and the magnet are movably sleeved, the magnetic isolation ring and the shell base body are also movably sleeved, a limiting groove hole is formed in the side wall of the shell base body corresponding to the magnetic isolation ring, a limiting screw is movably arranged in the limiting groove hole, and the limiting screw penetrates through the limiting groove hole and is fixedly connected with the magnetic isolation ring.

Compared with the screwdriver head handle or the electric screwdriver in the prior art, the utility model discloses a make great structural improvement with the sleeve part that above-mentioned instrument top is used for the construction. Handle top among the prior art is simple sleeve structure only, only has connection function, the utility model discloses through improving the back, increased magnet and can be around gliding magnetic ring structure, the absorption function of magnet can be fixed male batch head, prevents to take place to take off the phenomenon that drops that takes off in the construction, stops the incident, and slide around the magnetic ring and can change batch head position in the housing base, supplementary batch head random plug in the sleeve is changed, convenient construction, improvement work efficiency.

The present invention will be described in detail with reference to the accompanying drawings and examples.

The drawings illustrate:

the magnetic head comprises a magnet fixing body 1, a shell base body 2, a magnet 3, a magnetic isolation ring 4, a limiting screw 5, a limiting slotted hole 6, a head 7, a clamp spring groove 8 and a head mounting hole 9.

Detailed Description

Referring to fig. 1, 2 and 3, a quick-release magnetic head comprises a housing base 2, a hollow cavity is arranged inside the housing base 2, an inner hexagonal batch head mounting hole 9 suitable for mounting a batch head is arranged at the front end of the housing base 2, a magnet 3 is arranged in the cavity at the rear end of the housing base 2, the rear end of the magnet 3 is fixedly mounted on a magnet fixing body 1, the magnet fixing body 1 is fixedly connected with the housing base 2, a magnetic insulating ring 4 is mounted at the front end of the magnet 3, the magnetic insulating ring 4 is movably sleeved on the magnet 3, the magnetic insulating ring 4 is movably sleeved with the housing base 2, namely, the magnetic insulating ring 4 can freely slide back and forth in the cavity of the movable base 2, a strip-shaped limiting slot hole 6 is arranged on the side wall of the housing base 2 corresponding to the magnetic insulating ring 4, as shown in the figure, two limiting slot holes 6 are symmetrically arranged on the side wall of the housing base 2, and a limiting screw 5 is movably mounted in the limiting slot hole 6, after the two limiting screws 5 penetrate through the limiting groove holes 6, the two limiting screws are respectively fixedly connected with the two sides of the magnetic insulating ring 4, after the magnetic insulating ring 4 is assembled, the magnetic insulating ring 4 is locked in the cavity of the shell base body 2 through the limiting screws 5 and cannot slide out and fall off, and the front and back sliding displacement of the magnetic insulating ring in the cavity of the shell base body 2 is equal to the sliding displacement of the limiting screws 5 in the limiting groove holes 6.

The utility model discloses be fit for and criticize first handle or the supporting use of instrument such as electric screwdriver.

The utility model provides a magnet fixed body 1's effect is fixed magnet 3 in housing base member 2, and during the in-service use, magnet fixed body 1's structural design can have two kinds of modes:

one way is that the magnet fixing body 1 is an independent structure, namely, a magnet fixing body 1 is independently arranged in a shell base body 2 for fixedly connecting a magnet 3, when the quick-release magnetic head adopting the way is matched with tools such as a screwdriver handle or an electric screwdriver, the rear end of the quick-release magnetic head (the rear end of the shell base body 2 or the magnet fixing body 1) is in interference fit or in threaded connection with the handle body of the tools, and the like, the structure is complicated, and the production cost is increased;

the second mode is that the magnet fixing body 1 is the handle body part of tools such as a screwdriver head handle or an electric screwdriver and the like, and the structure mode is simple and practical and has low cost.

The usage principle of the present invention will be briefly described below by taking the second structure as an example.

Referring to fig. 4, fig. 4 shows the application of the present invention to the handle of the screwdriver head, the handle of the screwdriver head handle is the magnet fixing body 1, and the housing base 2 is fixedly connected to the front end of the handle (the magnet fixing body 1). Referring to fig. 5, when in use, the bit 7 is inserted into the bit mounting hole 9 at the front end, and the rear end of the bit 7 abuts against the magnetic isolation ring 4 and moves to expose the magnet 3 and is fixed by the magnet; referring to fig. 6, after the construction is finished, the limiting screw 5 is pinched by fingers to push forwards, so that the magnetic isolation ring 4 moves forwards and pushes forwards against the bit 7, the rear end of the bit 7 is separated from the magnet 3 and is not adsorbed by the magnet any more, and the bit 7 is taken out for replacement.

In general, the sliding displacement of the limiting screw 5 in the limiting slot 6 is designed to be 3-5mm, so that the use requirement can be met.

In addition, a clamp spring groove 8 can be formed in the outer wall of the shell base body 2, and when the product is used with a handle body of a tool such as an electric screwdriver in a matched mode, a clamp spring can be installed in the clamp spring groove 8 so that the shell base body 2 can be fixed and prevented from falling off.
