Description

Quick release socket tool

The invention relates to a hand tool, in particular to a quick release socket tool for installing a tool head.

Referring to FIG. 1 and FIG. 2, a quick-release socket tool 1 taking the Republic of China Invention Patent No. I544988 as an example, includes a rod body 11, a linkage device 12, and a fastening device 13. The quick release socket tool 1 is used for mounting a subhead 2. The rod body 11 extends in the axial direction with a slot hole 110 having an open front end, a fastening hole 111 adjacent to the front end and extending in the radial direction, and a long groove hole 112 penetrating radially and communicating with the slot hole 110. And a top edge 113 formed at the front end and surrounding the slot hole 110. The linkage device 12 has a first elastic member 121 compressively disposed on the bottom side of the slot hole 110, a sliding member 122 connected to the first elastic member 121 and having a through-limiting slot 120, and A guide pin 123 extending in the radial direction and movably penetrates the limiting groove 120 of the long groove hole 112 and the sliding member 122. The fastening device 13 has a beam ring 131 slidably mounted on the outside of the rod body 11 in the axial direction, and a first ring 131 compressively disposed between the beam ring 131 and the top edge 113 of the rod body 11. Two elastic members 132 and a positioning bead 133 movably received in the fastening hole 111. The bundle ring 131 is composed of an outer ring body 134 and an inner ring body 135, and has an inner ring groove 130 facing the positioning beads 133. Through the buckle of the positioning bead 133, the screwdriver head 2 can be positioned on the rod body 11 and the screwdriver head 2 can be installed on the quick release socket tool 1.

When the screwdriver head 2 is to be detached from the quick release socket tool 1, it is only necessary to push the beam ring 131 to move forward to the inner ring groove 130 pair located in the fastening hole 111 and retract the positioning bead 133 to The inner ring groove 130 reaches the position shown in FIG. 2. At this time, because the binding force applied by the positioning bead 133 to the screwdriver head 2 disappears, the elastic force of the first elastic member 121 is released, thereby pushing the slide. The piece 122 drives the guide pin 123 to move forward, and can automatically pull out the rod body 11 by moving the driver head 2 forward, thereby achieving the effect of replacing different driver heads.

Although the quick-release socket tool 1 can be used for assembling various screwdriver heads and applied to different working occasions, since the quick-release socket tool 1 uses the guide pin 123 and cooperates with the rod body 11 and the slide Only the long groove 112 and the limiting groove 120 passing through the element 122 can drive the first elastic member 121 and the second elastic member 132 to be squeezed to achieve the function of installing and removing the driver head 2. Therefore, the The quick release socket tool 1 has the problems of many components and complicated processing of the components. In addition, it is not easy to assemble the guide pin 123 to the outer ring body 134 and the inner ring body 135 of the beam ring 131 and the rod body 11, and there is still room for improvement.

Bonding strength of the header 72.

In actual use, the screwdriver head 9 is inserted into the hollow rod 41 of the main rod unit 4 of the first embodiment. The screwdriver head 9 presses the ejector seat 72 to move backward and makes the second elastic member 71 is compressed to accumulate an elastic restoring force. After the driver head 9 moves to the groove 91 aligned with the positioning hole 415 of the hollow rod 41, the stopper 43 will move toward the groove 91 and partly fall into the groove 91. The groove 91 allows the driver head 9 to be locked and positioned in the first embodiment. At this time, related operations such as screw lock can be started. It should be noted that, with the inclined surface q of the sliding surface portion 6211 of the inner casing 62, the stopper 43 can be smoothly moved between the sliding surface portion 6211 and the accommodating surface portion 6212, and the The stopper 43 is smoothly inserted into the groove 91 without pushing the sliding unit 6 to drive the stopper 43 into the groove 91, so that the user can install the screwdriver with one hand Head 9.

It should be particularly noted that the first embodiment makes the screwdriver head 9 more firmly assembled through the magnetic properties of the magnetic member 722, and does not accidentally come out during use, but in other variations, the first embodiment For example, the magnetic member 722 can be omitted, or the entire ejector seat 72 can be omitted, so that the free end 712 of the second elastic member 71 is in direct contact with the driver head 9, and the second elastic member 71 can also be Compression accumulates the effect of this elastic restoring force.

Referring to FIG. 6 and FIG. 7, when the operation is completed or needs to be replaced with another tool head (not shown), as long as the sliding unit 6 of the first embodiment is pushed forward (that is, pushed toward the driver head 9) ), So that the sliding unit 6 moves forward relative to the main lever unit 4 to the accommodating surface 6212 of the inner casing 62 to face the positioning perforation 415, and the stopper 43 moves to the accommodating surface 6212. And it is not exposed at the position of the inner peripheral surface 411 of the hollow rod 41. At the same time, the screwdriver head 9 is no longer restrained by the stopper 43 and the second elastic member 71 releases the elastic restoring force to drive the pusher. The jack 72 pushes the screwdriver head 9 to move forward, and because the elastic restoring force is greater than the magnetic attraction of the magnetic piece 722, the screwdriver head 9 can automatically disengage from the first embodiment. While pushing the sliding unit 6 forward, the movable end 52 of the first elastic member 5 will be driven by the outer casing 61 to be pressed in the direction of the fixed end 51 with an elastic restoring force. When the sliding unit is released At the moment of 6, the elastic restoring force of the first elastic member 5 will be released and pushed the outer casing 61 to move the sliding unit 6 back to the original position.

It should be particularly noted that, as shown in FIG. 8, in a variation of the first embodiment, the fixed end 51 of the first elastic member 5 does not need to be inserted into the snap ring groove 416 of the hollow rod 41, but passes through A C-shaped buckle 44 embedded in the snap ring groove 416 of the hollow rod 41 is used to achieve the limiting effect. At this time, the fixed end 51 and the movable end 52 of the first elastic member 5 respectively spring against the C-shape. The buckle and the outer casing 61 can also make the first elastic member 5 compressible to accumulate the elastic restoring force.

Through the above description, the advantages of the first embodiment can be summarized as follows:

1. In the first embodiment, the snap ring groove 416 is formed on the outer peripheral surface 412 of the hollow rod 41, and the fixed end 51 of the first elastic member 5 is embedded in the snap ring groove 416, and then respectively The front and rear sides of the hollow rod 41 can be assembled by inserting the inner casing 62 and the outer casing 61 into the hollow rod 41. Compared with the conventional technology, the present invention is more convenient in assembly.
