DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

Referring FIGS. 1 through 4, a screwdriver kit in accordance with the preferred embodiment in the present invention includes a main body 10, a linkage 20, a bit storage member 30, a cap member 40, a locking member 50 and a chunk member 60.

The main body 10 includes a first end 11 and a second end 12. The first end 11 is adapted for connecting to a tool such as a chunk or things like that. In this case, the chunk member 60 is detachably installed to the first end 11 and includes a bore 61 formed thereon and a magnetic portion 62 provided in the bore 61. The bore 61 is adapted for receiving to a tool such as a screwdriver bit of things like that. The magnetic portion 62 is adapted for attaching with the tool which is received in the bore 61.

A column 13 longitudinally extends from the second end 12 of the main body 10 and includes an opening 131 longitudinally formed therein. The opening 131 communicates with the interior of the main body 10. A transverse cross-section of the column 13 is preferably hexagon, and a transverse cross-section of the opening 131 is preferably hexagon. A slot 132 is formed on the outer periphery of the column 13 and adjacent to the extremity of the column 13 opposite to the second end 12 of the main body 10. The slot 132 is preferably U-shaped and has two legs. The legs of the slot 132 and the opening 131 are in communication with each other. A U-shaped fastener 133 is received in the slot 132 and inserted into the opening 131.

An engaged portion 14 are provided around the column 13 and against the second end 12. A diameter of the engaged portion 14 is smaller than that of the main body 10. Numbers of engaged recesses 141 are longitudinally formed on the outer periphery of the engaged portion 14 and space from each other. A slide rail 142 and three notches 143 are transversely formed on the outer periphery of the engaged portion 14. And the slide rail 142 and the notches 143 are closer to the second end 12 than the engaged recesses 141. The slide rail 142 communicates with the opening 131. A longitudinal cross-section area of the slider rail 142 is larger than the transverse cross-section area of the opening 131. The length of the slider rail 142 is smaller than the diameter of the engaged portion 14, and the slider rail 142 has one opening (not numbered) which is open to the periphery of the engaged portion 14.

The linkage 20 is slideably disposed in the opening 131. The cross-section of the linkage 20 which is preferably hexagon corresponds to that of the opening 131 so that the linkage 20 cannot rotate with respect of the opening 131. The linkage 20 has a first end and a second end. An annular groove 21 is provided on the first end of the linkage 20 adjacent to the main body 10. A cross-section of the annular groove 21 is preferably circular. A first elastic element 22 is disposed in the opening 131 and sandwiched between the linkage 20 and the chunk member 60. The fastener 133 is inserted into the opening 131 through the slot 132 and enables to grip on the annular groove 21 so that while the linkage 20 is pressed by the first elastic element 22 outwardly with respect of the opening 131, the fastener 133 is provided to restrict the linkage 20 for preventing the linkage 20 from detaching from the opening 131.

The bit storage member 30 includes a hexagon coupled hole 31 formed on the center thereof. The bit storage member 30 is mounted on the column 13 via the coupled hole 31. Numbers of first storage holes 32 and a second storage hole 33 are arranged on the bit storage member 30 around the coupled hole 31. Each of the first storage holes 32 is preferably hexagon. The first storage holes 32 are adapted for receiving various bits, and the second storage hole 33 is adapted for receiving a bit shank (not shown). A receptacle 144 is formed on the engaged portion 14 and corresponds to the second storage hole 33 so that the bit shank can be inserted through the second storage hole 33 and the receptacle 144 into the interior of the main body 10. A diameter of the bit storage member 30 is smaller than the diameter of the main body 10. Numbers of engaged recesses 34 are formed on the outer periphery of the bit storage member 30 annularly and respectively correspond to and similar to the engaged recesses 141 of the main body 10. At least one of longitudinal extensions 134 is formed on the outer periphery of the column 13 and adjacent to the second end 12 of the main body 10 as to prevent the bit storage member 30 from abutting against the main body 10.

The cap member 40 is able to be attached with the engaged portion 14 of the main body 10, and the linkage 20 is received in the cap member 40. A compartment 41 is defined in the cap member 40, and a connected hole 411 is formed in the bottom of the compartment 41. The second end of the linkage 20 is installed to the connected hole 411. The cap member 40 is slideable along the linkage 20 between a first position and a second position. In the first position, the cap member 40 is attached with the main body 10. In the second position, the cap member 40 is detached from the main body 10. Furthermore, numbers of studs 412 are formed on the interior side of the compartment 41 and correspond to the engaged recesses 141 of the main body 10 as to couple the cap member 40 to the main body 10 as the cap member 40 is in the first position. Alternatively, the cap member 40 can be adapted for storing bits or a bit shank as to omit the bit storage member 30.

Referring to FIGS. 2 and 5, the locking member 50 is adapted for restricting the cap member 40 in the first position and includes a clip 51, a detent 52 and a second elastic element 53. The clip 51 is preferably C-clip and has a gap 511 and three notches 512. The width of the gap 511 is same as the width of the slide rail 142, and the notches 512 respectively correspond to the notches 143 as to couple the clip 51 on the outer periphery of the engaged portion 14 for preventing the engaged portion 14 from exposing outside. The detent 52 is slideably disposed in the slide rail 142 and has a first end and a second end. A through-hole 521 is defined on the detent 52 between the first and second ends of the detent 52 and corresponds to the opening 131. The second elastic element 53 is provided between the second end of the detent 52 and the slide rail 142 as to engage the through-hole 521 of the detent 52 with the annular groove 21 of the linkage 20. Hence, the cap member 40 is fixed to the first position and attached with the main body 10. A restricting portion 522 is provided on the detent 52 adjacent to the second end of the detent 52 and engaged with a receiving hole 145 formed on the main body 10 as to prevent the detent 52 from detaching from the slide rail 142. In addition, cooperation of the outer periphery of the second end of the detent 52 and the clip 51 exactly form a whole ring profile for aesthetic.

Referring to FIGS. 6 through 8, after pressing the detent 52 toward the main body 10, the through-hole 521 of the detent 52 is disengaged from the annular groove 21 and the linkage 20 is not restricted by the detent 52 any more. And then, the first elastic element 22 pushes the linkage 20 to detach from the main body 10 and the cap member 40 is driven to move to the second position from the first position till the fastener 133 is engaged with the annular groove 21. Therefore, the fastener 133 is adapted for preventing the linkage 20 from detaching from the opening 131, and in the same time, the bit storage member exposes outside so that it is easy and convenient to take the bits or the bit shank to connect with the chunk member 60 (as shown in FIG. 6).

Thus since the invention disclosed herein may be embodied in other specific forms with out departing from the spirit or general characteristics thereof, some of which forms have been indicated, the embodiments described herein are to be considered in all respects illustrative and not restrictive. The scope of the invention is to be indicated by the appended claims, rather than by the foregoing description, and all changes which come with the meaning and range of equivalency of the claims are intended to be embraced therein.
