When the shaft tool 4 is combined (such as a word, cross or a hexagonal screwdriver rod), the clutch unit 2 can be pulled up to be opened, and then the required shaft tool 4 is placed in the first group. The portion 12 is released from the clutch unit 2, and the clutch unit 2 is fastened to the shaft tool 4, and the assembly of the shaft tool 4 is completed. Thus, the adapter 1 can be driven by the power tool 3, and The shaft tool 4 locks or removes a word, cross or hexagon socket screw. When the shaft tool 4 is to be removed or replaced, the clutch unit 2 is pulled up to be in an open state, and then a pulling force is applied to the shaft tool 4 to remove the shaft tool 4 or perform Replace the other shaft tool 4 (as shown in Figure 3).

When the sleeve tool 5 is combined (such as a hexagonal sleeve of different sizes), after the shaft tool 4 is removed, the sleeve tool 5 is directly sleeved to the second assembly portion 13 and utilized. The socket tool 5 locks or unloads the hex bolts (as shown in Figure 4).

In this way, the adapter 1 and the clutch unit 2 can be used to make the power tool 3 applicable to the shaft tool 4 or the sleeve tool 5 respectively, thereby achieving the advantages of convenient carrying and easy operation.

In a preferred embodiment of the present invention, the first assembly portion 12 has a through hole 121 and a plurality of first restriction surfaces 122. The through hole 121 is disposed at a central axis of the shaft 11 and the first restriction surface. The 122-phase connection is disposed on the inner circumference of the shaft 11 and opposite to the through-hole 121. The first restriction surfaces 122 are six, so that the first assembly portion 12 forms a hexagonal perforation.

Thereby, the shaft tool 4 of the outer hexagon can be inserted into the first set of the joints 12 which are the hexagonal perforations; and the shaft tool 4 can be directly inserted into the through holes 121 when being worn, and The plurality of flat portions 41 of the outer peripheral edge of the shaft tool 4 are respectively abutted against the first restricting surfaces 122, and the clutch unit 2 is fastened to the shaft tool 4, thereby the first group connecting portion 12 is borrowed. Cooperating with the first limiting surface 122, the through hole 121 is provided with an outer hexagonal shaft tool 4 for radial limitation, and the clutch unit 2 is coupled to the shaft tool 4 for axial limitation. The shaft tool 4 is firmly coupled to the first set of joints 12 to achieve the effect of avoiding falling off.

In a preferred embodiment of the present invention, the second assembly portion 13 has a plurality of second restriction surfaces 131, and the second restriction surfaces 131 are connected to the outer circumference of the shaft 11. The face 131 is six, so that the second set of joints 13 form an outer hexagonal rod body.

Thereby, the socket tool 5 in the hexagonal socket can be sleeved on the second set portion 13 which is the outer hexagonal rod body; and the socket tool 5 can be directly sleeved on the second group connection when the socket is sleeved. The portion 13 and the plurality of flat portions 51 on the inner circumference of the sleeve tool 5 abut against the second limiting surfaces 131, respectively, so that the second connecting portion 13 is matched by the second limiting surfaces 131. The sleeve tool 5 is provided for radial limitation after it is provided. The sleeve tool 5 is firmly coupled to the second set of joints 13 to achieve the effect of avoiding falling off.

In the preferred embodiment of the present invention, the clutch unit 2 includes a movable sleeve 21, a pushing portion 22, a first elastic member 23, a limiting member 24, a buckle 25, and a spacer 26. And a second elastic member 27, the movable sleeve 21 is movably disposed on the shaft body 11. The urging portion 22 is disposed on the inner edge of the movable sleeve 21. The first elastic member 23 is sleeved on the shaft 11 The two ends of the first elastic member 23 are respectively abutted against the shaft 11 and the pushing portion 22, and the limiting member 24 is movably disposed on the shaft 11 and adjacent to the pushing portion 22, and the buckle 25 is fastened. In the shaft 11, the spacer 26 is sleeved on the shaft 11 and abuts against the buckle 25, and the second elastic member 27 is sleeved on the shaft 11. The two ends of the second elastic member 27 are respectively The pushing portion 22 and the spacer 26 are abutted. The rod body 11 has a matching hole 111 that communicates with the first group of the connecting portions 12 . The limiting member 24 is movably disposed on the through hole 111 , and the limiting member 24 can be a ball. The pushing portion 22 can be The movement of the movable sleeve 21 abuts or disengages the limiting member 24, so that the limiting member 24 moves in the through hole 111 to move in or out of the first assembly portion 12.

Therefore, when the adapter 1 is coupled to the shaft tool 4, the movable sleeve 21 of the clutch unit 2 can be pulled up to disengage the pushing portion 22 that originally abuts the limiting member 24. And the limiting member 24 is removed from the first connecting portion 12 by the through hole 111, the first connecting portion 12 is opened, and the second elastic member 27 is compressed, and then the required shaft tool is used. 4 is disposed in the first set of joints 12 and releases the movable sleeve 21, so that the second elastic member 27 pushes the movable sleeve 21 downward due to elastic release (at this time, the first elastic member 23 is In the compressed state, the pushing portion 22 is abutted against the limiting member 24, so that the limiting member 24 moves in the through hole 111 and moves into the first connecting portion 12, thereby allowing the limiting member 24 to buckle The fitting 42 of the shaft tool 4 is connected to complete the assembly of the shaft tool 4. When the shaft tool 4 is to be removed or replaced, the movable sleeve 21 is pulled up to disengage the pushing portion 22 that originally abuts against the limiting member 24, and the limiting member 24 is allowed to pass through the through hole. The first set of joints 12 are removed from the first set of joints 12 and the retaining grooves 42 are removed from the through-holes 111 to open the first set of joints 12 . Then, by applying a pulling force to the shaft tool 4, the shaft tool 4 can be removed or another shaft tool 4 can be replaced. And achieve the function of easy to use.
