Description

Socket

The present invention relates to a hand tool, and more particularly to a socket joint for splicing a workpiece.

Typically, when a workpiece is driven by a pneumatic or electric tool, a set of joints is typically placed between the pneumatic or power tool and the workpiece. The conventional sleeve joint includes a receiving groove. In order to enable the workpiece to be more stably positioned in the receiving groove, a tip is formed at one end of the workpiece, and the workpiece ring is provided with a tenon, and the sleeve is attached to the bottom of the receiving groove. A limiting slot is further defined in the wall, the limiting slot is configured to receive a body, and a magnet is fixed on the body, the top of the magnet protrudes from the seat body, and the groove of the head of the workpiece is grooved The bottom portion can abut against a portion of the magnet protruding from the seat body, and the remaining portion of one end of the head of the workpiece abuts against the bottom wall of the pocket, the tenon abutting against one end of the sleeve. Wherein, the seat system is made of aluminum-containing material such as aluminum or aluminum alloy, so that the width of the seat body can be slightly larger than the width of the limit groove, so that when it is installed in the limit groove, it can be slightly deformed and limited The groove wall of the groove is tightly fitted.

However, when the seat body is installed in the limiting slot, it is difficult to control the depth at which the seat body is inserted into the limiting slot. When the depth of the seat plug is too shallow, the magnet is too convex. In this case, except for the head of the workpiece. The groove bottom of the groove of the portion can abut against the portion of the magnet protruding from the seat body, the tenon cannot abut against one end of the sleeve joint, and the rest of the end of the head of the workpiece cannot be abutted The bottom wall of the tank, in this way, the reaction force generated by the impact force of the workpiece on the pneumatic or electric tool will be directly absorbed by the magnet, causing the magnet to be easily crushed by the workpiece.

In the case where the depth of the body plug is too deep, the groove bottom of the groove of the head of the workpiece cannot be abutted against the portion of the magnet protruding from the seat body, so that the magnet has an adsorption force on the workpiece. Greatly weakened, causing the workpiece to easily fall out of the pocket.

In order to improve the above problems, the conventional sleeve connector of TW M402173 is available, but when the head of the workpiece is accommodated in the groove of the sleeve, the head of the workpiece only abuts against the magnet, and the rest is suspended. When the elastic member is contracted to the bottom of the groove of the limiting groove to the minimum, although the elastic member has absorbed the reaction force generated by most of the workpiece, the remaining reaction force is still absorbed by the magnet, so that the magnet is still easily crushed.
