Description

Adapter structure

The invention relates to a joint structure, in particular to a joint structure, the sleeve is sleeved at the first sleeve portion, and the ratchet wrench is sleeved with the second sleeve portion, the ratchet wrench The working end is close to or fastened to the first abutting portion of the first bead body, and the first bead body is restricted by the active end of the ratchet wrench without a large retracting distance, and the sleeve cannot be self-contained The first set of joints is removed.

As previously known to us, the conventional adapter structure, such as U.S. Patent No.: US5509333, is supplemented by the eleventh and twelfth drawings of the patent publication, the structure of which is: a body 172, A first sleeve portion 174 having a quadrangular shape is disposed at one end of the body 172, and a second sleeve portion 184 is disposed in the body 172. The second sleeve portion 184 is in the shape of a square groove for the hand tool member. The sleeve 208 is formed in a circular groove shape on one side of the body 172. The elastic member 212 and the bead body 214 are disposed on the elastic member 212 and the bead body 214. In the pocket 208, the elastic member 212 is elastically engaged between the pocket 208 and the bead 214.

However, the absence of the conventional structure is as follows: the first set of portions 174 and the sleeve 30 of the body 172 are shown in Figure 14 of the bulletin. When the sleeve is engaged, the user needs to apply a slight force to fit the sleeve 30 to the first sleeve portion 174. The inner circumferential surface of the sleeve 30 is pressed against the beads 214 to make the beads. The body 214 is retracted against the elastic member 212. When the sleeve 30 is completely engaged with the first sleeve portion 174, the elastic member 212 is elastically returned, so that the bead body 214 abuts against the sleeve 30. In the bead pocket 230, the sleeve 30 is limited by the elastic force of the bead body 214 and the elastic member 212, but when the sleeve 30 rotates the screwing member, the sleeve 30 is outwardly received. When the force is removed, the bead body 214 can be pressed against the sleeve 30 and completely immersed in the pocket 208, and the sleeve 30 is disengaged from the first sleeve portion 174. 30 is only disengaged from the first nesting portion 174 by the elastic force of the elastic member 212, and the fitting is unacceptable.

In view of the above-mentioned lack of the conventional 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 drawbacks of the adapter structure.

In the conventional adapter structure, the sleeve is only disengaged from the first fitting portion by the elastic force of the elastic member, that is, the sleeve is unconfirmable. In the adapter structure of the present invention, the sleeve is sleeved at the first sleeve portion, and the ratchet wrench is engaged with the second sleeve portion, and the working end of the ratchet wrench is close to or tied to Abutting the first abutting portion of the first bead body, the first bead body is restricted by the active end of the ratchet wrench without a large retracting distance, and the sleeve cannot be self-contained Removing the portion, if the sleeve is to be removed from the first sleeve portion of the body, the active end of the ratchet wrench is first disengaged from the second sleeve portion, so that the first The bead system is not limited to the ratchet wrench, and the sleeve can be self-contained Take off the ministry.

An adapter structure includes: a first sleeve portion and a second sleeve portion at one end of the body, wherein the second sleeve portion is such that the first sleeve portion has a slightly thin shell shape. The system is provided with a first receiving groove, the opening of the first receiving groove is disposed on one side of the first fitting portion, and the first receiving groove is in communication with the second fitting portion; a first bead system a first semi-circular bead shape, the first bead system is disposed at a near opening of the first cavity of the body, and one end of the first bead is exposed outside the first cavity, the first bead The system is provided with a first abutting portion, the first abutting portion is opposite to the second fitting portion, and the first abutting portion is aligned with the inner side surface of the second fitting portion; In the first receiving groove, the elastic member is elastically engaged between the first receiving groove and the first bead, and the elastic member is provided with an elastic portion, and the elastic portion is opposite to the second engaging portion. .

The sleeve is sleeved on the first sleeve portion, and the bead system is abutted against the inner wall surface of the sleeve by the elastic top of the elastic member, and the ratchet wrench is coupled to the second sleeve portion. Engaging, the working end of the ratchet wrench is close to or fastened to the first abutting portion of the first bead body, and the first bead body is limited by the active end of the ratchet wrench without being larger Shrinking distance, that is, the sleeve is limited to the first bead body, the first bead system is limited to the ratchet wrench, and the sleeve cannot be removed from the first fitting portion, if The sleeve is removed from the first sleeve portion of the body, and the active end of the ratchet wrench is first disengaged from the second sleeve portion, so that the first bead system is not limited to the ratchet The wrench can be removed from the first sleeve.
