Description

Hand tool fitting structure

The present invention relates to a hand tool fitting structure, and particularly refers to a hand tool fitting structure in which the second fitting piece is compatible with the first end, and the first fitting piece is matched with the accommodating groove. Specifications.

The commonly used hand tool sleeve joint structure, such as the sleeve joint structure previously applied by us, Taiwan patent application number: 102107972, certificate number: I444258, patent name: sleeve joint structure, its structure is: a body 10 is provided with a first end 11, a second end 12, a receiving groove 13 and an abutment 14; a fixed ring 20 is received in the receiving groove 13, the fixed ring 20 is provided with a abutment 21, the abutment 21 is tightly fitted at the inner circumference of the receiving groove 13; a sleeve 30 is received in the body 10, one end of the sleeve 30 is provided with a receiving groove 31, the other end of the sleeve 30 is provided with a ring-shaped clamping portion 32, the clamping portion 32 is circular The clamping part 32 is conical, and a plurality of through grooves 33 are provided at the clamping part 32. The sleeve 30 and the receiving groove 31 are provided with a convex ring 34 on the same side. The outer diameter of the clamping part 32 is larger than the inner diameter of the fixed ring 20. The clamping part 32 is provided with a plurality of through grooves 33, so that the clamping part 32 is easier to shrink and press into and pass through the fixed ring 20, so that the clamping part 32 is restricted by the fixed ring 20. The clamping part 32 is accommodated in the receiving groove 13, and the clamping part 32 is displaced a distance between the fixed ring 20 and the abutment 14; A magnetic body 40 is fixed in the receiving groove 31; an elastic element 60 is accommodated in the receiving groove 13, and the elastic element 60 is elastically abutted between the abutment 14 and the sleeve 30.

However, the deficiencies of this patent case are that the fitting part 30 is provided with the receiving groove 31 for the magnetic body 40 to be accommodated, and the other end of the fitting part 30 is provided with the locking part 32 and the plurality of through-slots 33 Nested with the fixing ring 20, the fitting piece 30 is accommodated between the accommodating groove 13 and the first end 11. The first end 11 has several different shapes, such as hexagonal grooves, twelve Angular grooves, polygonal grooves, gear shapes, or various shapes that can fit various screw parts. The size specifications of the receiving groove 13 will be produced in several specifications due to the size of the first end 11. The fitting parts 30 is due to the change in specifications of the first end 11 and the accommodation groove 13, and it is necessary to manufacture a variety of sizes to match the compatible device. For example, when there are 6 groove shapes and when there are 3 specifications of the accommodation groove 13, The kit 30 needs to be manufactured in 18 pieces, and the structure of the kit 30 that needs to be manufactured in various specifications is a drawback of this conventional patent.

In view of the shortcomings of the above-mentioned patent structure, the inventor has used many years of production, design and manufacturing experience in related industries to finally come up with a product that is practical and can improve the shortcomings of conventional use.

In the conventional hand tool sleeve structure, the sleeve part needs to be manufactured in various sizes to match the specifications of the first end and the receiving groove. In the hand tool sleeve structure of the present invention, the second sleeve part matches the first end, the first sleeve part matches the specifications of the receiving groove, the first sleeve part matches the receiving groove, and the second sleeve part matches the first end, so each has its own function, and the number of each can be less.

The invention relates to a hand tool fitting structure, which includes: a first system provided with a first end, a second end, a receiving groove and a first resisting edge; a fixed ring is accommodated in the In the accommodating groove, the fixed ring is provided with a resisting portion; a first fitting component is provided with a convex ring, a second resisting edge and a first locking portion; and a second fitting component is connected with the third fitting portion. A set of fitting parts is assembled. The second fitting part does not come out of the first body. The second fitting part is synchronously displaced with the first fitting part. One end of the second fitting part is A receiving groove and a second locking part are provided; a magnetic system is fixed in the receiving groove; an elastic element is accommodated in the receiving groove, and the elastic element springs against the first resisting edge and the first Between the set pieces, the first set piece has a return function.

When the first end is in various shapes, such as hexagonal slot, twelve-angle slot, polygonal slot, gear, star or various shapes that can be fitted with screw fittings, it is only necessary to change the specifications of the second fitting to match the first end, and the size of the receiving slot is relatively small. The first fitting matches the required specifications of the receiving slot, the first fitting matches the receiving slot and the second fitting matches the first end, and each has its own function. The number of the first fitting and the second fitting can also be small.

In order to enable the members of the Jun Bureau and those familiar with this technology to fully understand the effects of the present invention, the structure and composition of the present invention are explained below with diagrams and figure numbers. However, the following is only used to explain the implementation examples of the present invention and is not intended to limit the present invention in any form.
