Magnetic sleeve structure

The invention relates to a magnetic sleeve structure, in particular to a magnetic sleeve structure, the clamping member is fastened on the body, and the clamping component is received in the collar, the clamping component and the sleeve The inter-ring system is loosely fitted, so that the collar system can be displaced on the clamping member, and the system does not need to be processed.

As previously known by us, the conventional magnetic sleeve structure, such as the US Patent No.: US7107882B1, Taiwan Patent Application No.: 093126912, certificate number I254660, patent name: anti-loose screwdriver head attached magnetic sleeve, The structure of the patent system is: an anti-loose screwdriver head-attached magnetic sleeve, the magnetic sleeve 10 is a hollow sleeve body, and the sleeve hole 11 can be sleeved on the existing screwdriver head rod 20, and by the same The magnetic member 40 provided at one end provides an auxiliary adsorption force, thereby increasing the close adhesion between the screwdriver head rod 20 and the screwing member 40. The feature is that the sleeve hole 11 of the magnetic sleeve 10 and the driver head rod 20 are more corresponding. The card edge portion 12 and the card slot portion 21 are provided, wherein the card slot portion 21 is configured to allow the card edge portion 12 to be displaced by a predetermined distance therein, and the magnetic sleeve 10 can be slid at a predetermined distance and can be The magnetic head sleeve 10 is made of a tough material so that the card edge portion 12 of the sleeve hole 11 can be forced to pass over the screwdriver head end 22 in a tight manner, and the card edge portion is repeated. 12 When the card slot portion 21 of the screwdriver head 20 is reached, the original inner diameter can be retracted to achieve the card. The state's.

However, the lack of this conventional magnetic sleeve structure is:

1. The sleeve hole 11 and the driver head rod 20 are correspondingly provided with a card edge portion 12 and a card slot portion 21, and the card slot portion 21 is configured to allow the card edge portion 12 to be displaced by a predetermined distance therein. That is, the card holder portion 21 needs to be separately processed in the outer periphery of the screwdriver head 20 to displace the card edge portion 12 of the magnetic sleeve 10 at the card slot portion 21, that is, the magnetic sleeve 10 can only be provided. The hand tool member of the card slot portion 21 is sleeved, that is, the sleeve hole 11 of the magnetic sleeve 10 cannot be set on the existing driver head rod, and the expandability is insufficient.

2. In addition, as shown in Figures 1 and 2 of the U.S. Gazette, the inner diameter of the card edge portion 12 of the sleeve hole 11 of the magnetic sleeve 10 needs to be smaller than the outer diameter of the driver head end 22 of the driver bit rod 20. Basically, the magnetic sleeve 10 should be made of a hard plastic material, and the card edge portion 12 is forced to pass over the screwdriver head end 22, and when the card edge portion 12 reaches the card slot portion 21 of the screwdriver head rod 20, the retraction is restored. The original inner diameter, and the card edge portion 12 is required to be slightly supported, the pressing force of the card edge portion 12 needs to be large, and the card edge portion 12 of the magnetic sleeve 10 is easily damaged.

In view of the above-mentioned lack of the conventional magnetic sleeve structure, the inventors have been engaged in the manufacturing, production and design experience of related industries for many years, and finally have a product that can solve the disadvantages of the magnetic sleeve structure.

The outer circumference of the screwdriver head of the conventional magnetic sleeve structure The card slot portion needs to be separately processed to make the card edge portion of the magnetic sleeve displace at the card slot portion, and the present invention is related to a magnetic sleeve structure, especially a magnetic sleeve structure. The clamping member is fastened on the body, and the clamping member is received in the collar, the clamping member and the collar The inter-system is loosely fitted, so that the collar can be displaced on the clamping member, and the system does not need to be processed.

A magnetic sleeve structure, comprising: a system The utility model has a working end; a ring system is sleeved with the body, the ring system is provided with a first receiving groove, a first pivoting portion, a second receiving groove and a flange; and a clamping member is provided with a locking portion The clamping portion is fastened to the body, and the locking portion is fastened to the body. The clamping member is received in the first pivot portion, and the clamping member is loosely engaged with the first pivot portion. Disposing the collar system on the clamping member, that is, the collar is displaceable on the body, the clamping member is provided with a first end and a second end, the first end is aligned The abutting edge has a spacing distance between the first end and the abutting edge, that is, a maximum distance that the collar can be displaced on the body, the second end is aligned with the first receiving groove; The magnetic component is fixed to the first cavity, and one end of the magnetic component is abutted against the second end, and the magnetic component is provided with a third cavity, the third cavity and the first pivot The portion is relatively positive, and the working end portion is exposed outside the magnetic member.

The carding portion of the card member is tightly coupled to the body The card member is disposed in the first pivot portion of the collar, and the card member is loosely engaged with the collar, so that the first pivot portion can be on the card member. Displacement of a distance, the system does not need to process any ring groove, the magnetic sleeve structure can be combined with any body, that is, more practical and expandable.
