The disclosure of the utility model of Taiwan Utility Model Registration Certificate No. M591462 (Patent Document 1) can be referred to, and in the above-mentioned prior art, the disclosed coupling member is a square drive for assembling the socket with a sleeve. A housing recess having a portion having a portion and having an outer diameter larger than that of the square drive portion is formed at one end of the square drive portion so that the cylindrical portion formed on the base is correspondingly assembled by a sleeve. A fall-prevention component and a step-by-step positioning component are formed on the accommodating recess and the columnar structure, and the fall-prevention component is used to prevent the base and the coupling member from falling off from each other and is step-by-step. When the coupling member is rotated, the positioning component provides a feeling of fitting positioning step division having two direction change angles.

However, in the actual application experience, it was found that the structural form of the conventional socket stand described in the previous paragraph still has some problems. For example, a fall-prevention component and a stepped positioning component are formed in the same ring ring portion region on the accommodating recess and the cylindrical structure, and under this type of morphological construction design, the peripheral wall of the accommodating recess is formed. In, a multi-location introverted convex mass morphology is adopted, and this kind of structure is relatively complicated in the mold if the mold release is to be achieved smoothly during the injection molding operation. Since it is necessary to add a sliding mass and an interlocking mechanism related thereto, there is a problem that the manufacturing cost is significantly increased. In addition, the standard of the coupling member is set according to the standard of the socket. Therefore, when the standard of the socket is relatively small, the standard of the coupling member also needs to be relatively reduced. be. However, under this state, due to the under-inner diameter of the accommodating recess, the installation space for the above-mentioned slide mass for mold release may be insufficient, which causes a problem that it cannot be concretely realized.
