Description

Sleeve structure

The invention relates to a sleeve structure, in particular to a sleeve structure provided with a sleeve member and sleeved in the body. The sleeve structure has only the body and the sleeve member, and has less Component costs.

According to my previous knowledge, the conventional sleeve structure, such as U.S. Patent No. 5960682, Taiwan Patent Application No. 87108371, patent name: Wrench for Martian Plugs, a wrench for Mars Plugs, is composed of the following (A), ( B) and (C) are composed of three elements: (A) On the opposite side of the angle wrench body 1 provided with the operation part 2 for fitting the front corner of the handle, a Mars plug 3 for inserting a Mars plug 3 is formed. Fitting portion 4; (B) A ring surface provided with a bottom surface of the fitting recess 4 is inserted into the bottom of the fitting recess 4 of the Mars plug 3, and the edge portion of the ring surface extends upward to communicate with A plurality of buckling plate springs 5b, 5c of the spark plug 3 fixing member 5 in contact with the inner wall surface of the fitting recess 4; and (C) the bottom of the above-mentioned fitting recess 4 is inserted into the bottom of the fitting recess 4, such as yellow Low-hardness guide member 6 such as copper.

But the lack of this conventional structure lies in:

1. A fixing member 5 and a guide member 6 need to be provided in the fitting recess 4. As shown in the third figure of the bulletin, the guide member 6 should be fixed to the fixing member 5. Generally speaking, the guide The component 6 should be a plastic part. The wrench body 1 has about dozens of specifications. In this way, there are different sizes of the guide member 6 to match the wrench body 1 of various specifications. The guide member 6 will increase. The Mars plug sleeve cost.

2. The fitting recess 4, the fixing member 5 and the guide member 6 should be a tight fit structure. When the fixing member 5 and the guide member 6 are assembled in the fitting recess 4, assembly will be increased. Difficulty.

In view of the lack of the conventional sleeve structure mentioned above, the inventor has, through many years of experience in manufacturing, production and design in related industries, finally came up with a sleeve structure product that can solve the disadvantages of conventional use.

The sleeve structure should be used in different sizes. The plurality of guide members are matched with wrench bodies of various specifications, and the guide members increase the cost of the spark plug sleeve. The sleeve member of the sleeve structure of the present invention is integrally formed and is sleeved in the body. The sleeve structure has only two components of the body and the sleeve member, and has less component cost.

A sleeve structure includes: a body and a The end is provided with a first fitting portion, a plurality of receiving portions, a first clamping portion and a protruding portion; a set of fittings is fitted in the first fitting portion, and the fitting is provided with a plurality of connecting portions Each connection part is accommodated at each accommodation part, and one end of each connection part is connected with a spring abutment part and a spring abutment surface, and the spring abutment surface is slightly protruded from the end surface of the projection part. A second clamping portion is extended at the end of the resilient portion, and the second clamping portion is clamped at the first clamping portion so that the engaging piece does not come out of the first sleeve. Outside the joint.

The engaging piece is engaged with the first set of the body At the joint portion, each resilient portion of the set is accommodated at each receiving portion, and the resilient portion is connected with the receiving portion. The wall surfaces of the accommodating part are separated from each other. The resilient part has a first length, and each of the to-be-rotated parts has a different length. The first length of the resilient part can be used for the rotating parts of various specifications. Set. The sleeve is integrally formed, and the sleeve structure has only two components of the body and the sleeve, and has less component cost. The second clamping portion is clamped at the first clamping portion, so that the engaging member is restricted by the first clamping portion and the second clamping portion without falling out of the first engaging portion. Therefore, it is only necessary to drill the main body with the first clamping portion, which will not increase the cost of processing the main body.

In order to fully understand the effects of the present invention by members of the Bureau and those skilled in the art, the structure and composition of the present invention are described in conjunction with the drawings and figures, but the following are only used to explain the implementation of the present invention For example, it is not intended to limit the present invention in any form, and any modification made under the spirit of the present invention should still fall within the protection scope of the present invention.
