DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
[0021] Referring to FIGS. 1 and 2, the tool of the present invention comprises an elongate body 10, a first engaging portion 11 formed at the first end of the body 10 and a first groove 12. A passage 15 is defined in the body 10. The first groove 12 is circularly along the central axe of the body 10 and the passage 15, and defined in the outside of the first engaging portion 11. The first engaging portion 11 is a non-circular portion. The first groove 12 is a semi-circular groove viewed in transversal cross section and located substantially at the middle portion of the first engaging portion 11. A second engaging portion 13 is located at the distal end of the first engaging portion 11 and is a tubular portion. A second groove 14 is circularly along the axe of the passage 15 defined in the outside of the second engaging portion 13 and located close to the distal end of the second engaging portion 13. The second groove 14 is a semi-circular groove viewed in transversal cross section. The diameter of the second groove 14 is smaller than that of the first groove 12. A function end 16 is formed at the second end of the body 10. The passage 15 is defined axially through the body 10 and communicates with the function end 16. In this embodiment, the body 10 is a socket, and the passage 15 is a circular passage or a rectangular passage. The function end 16 is a polygonal recess.
[0022] As shown in FIG. 3, a first hand tool 20 such as a ratchet wrench or a box-end wrench as shown, the first hand tool 20 has a polygonal third engaging portion 21 with which the first engaging portion 11 is engaged. The first engaging portion 11 is a hexagonal portion. The third engaging portion 21 has a bead 22 resiliently engaged with the first groove 12. When the first engaging portion 11 is engaged with the third engaging portion 21, the bead 22 can roll within the first groove 12.
[0023] As shown in FIGS. 4 and 5, a second hand tool 30 such as a ratchet wrench or a box-end wrench as shown, the second hand tool 30 has a polygonal fourth engaging portion 31 with which the first engaging portion 11 is engaged. The fourth engaging portion 31 is a hexagonal recess. The second hand tool 30 has a switch 300, and the switch 300 has a connection member 32 which has a rounded distal end 320. When the first engaging portion 11 is engaged with the fourth engaging portion 31, the rounded distal end 320 of the connection member 32 is engaged with the second groove 14 to prevent the body 10 from dropping from the fourth engaging portion 31.
[0024] FIG. 6 shows that the body 10 is a connector and the function end 16 is a rectangular head which is engaged with a rectangular recess of other tools.
[0025] FIGS. 7 and 8 show that the cross section of the second engaging portion 13 is the same as that of the first engaging portion 11. The second engaging portion 13 and the first engaging portion 11 are a hexagonal portion respectively.
[0026] FIGS. 9 and 10, the cross section of the second engaging portion 13 is the same as that of the first engaging portion 11. Each of the first and second engaging portions 11, 13 is a tubular portion and has multiple grooves 17 in equidistance defined in the outside thereof and parallelly extending along the axe of the passage 15.
[0027] FIG. 11 shows that the body 10 is a connection rod. FIG. 12 shows that the body 10 is a pivotable connector. The passage 15 is a rectangular passage so as to be connected with a rectangular head.
[0028] Yet another embodiment of the present invention shows that the first groove 12 has a color and the second groove 14 has another color, such that the users can quickly distinguish the first and second grooves 12, 14.
[0029] The advantages of the present invention are that the body 10 has a first groove 12 and a second groove 14. A shown in FIGS. 3 to 5, the body 10 is engaged with the third engaging portion 21 of the first hand tool 20, the bead 22 is engaged with the first groove 12.
[0030] When the first engaging portion 11 is engaged with the fourth engaging portion 21 of the second hand tool 30, the connection member 32 of the second hand tool 30 is engaged with the second groove 14. The body 10 of the present invention can be cooperated with the first and second hand tools 20, 30.
[0031] As shown in FIGS. 6, 11 and 12, the body 10 of the present invention can be a socket, a connector, connection rod or a pivotable connector. The body 10 may be used in different ways.
[0032] As shown in FIG. 9, there are multiple grooves defined in the outside of the first and second engaging portions 11, 13. The multiple grooves are annular grooves. The hand tool to be cooperated with the body 10 of the present invention has multiple ridges protruding therefrom, so that the ridges are engaged with the grooves when the body 10 of the present invention is connected to the hand tools. Therefore, the body 10 of the present invention can be cooperated with at least three different ratchet wrenches.
[0033] While we have shown and described the embodiment in accordance with the present invention, it should be clear to those skilled in the art that further embodiments may be made without departing from the scope of the present invention.
