Abstract

A composite wrench kit includes a handgrip 10 coupling with a mating sliding cap 15 to hold a hex wrench (a) for turning and fastening. The handgrip further is coupled with a coupling ring 20 which has a wedge flute 21 on the periphery to engage with a first wrench housing 30. The periphery of the first wrench housing 30 may be coupled with a second wrench housing 40 and a hanging hook 50. One or two sets of hex wrenches of British system and metric system and varying sizes may be held in the kit for use. The first and second wrench housing and the hanging hook may also be coupled to become one set for sales. The kit may be configured in various combinations and hung on user'"'"'s waist belt to facilitate carrying and use.

Claims

1. A composite wrench kit, comprising:

a rod-shaped handgrip which has at least one bulged wall on the outer periphery and a brake section formed radially on an inner wall;

a hollow coupling ring for coupling on the handgrip having a trough on an inner wall corresponding to the bulged wall, an indented retaining port on one end of an inner side of the trough, and at least one wedge flute on an outer wall;

a first wrench housing having a plurality of first insertion bores of varying sizes formed on one end surface, a coupling section on an outer wall to wedge in the wedge flute of the coupling ring, and a retaining ring formed on the outer wall; and

a second wrench housing formed substantially an annular hook to couple on the first wrench housing having a coupling member on an inner wall to couple with the retaining ring of first wrench housing, and a plurality of insertion bores of varying sizes formed on an outer end surface of the second wrench housing.

2. A composite wrench kit as claimed in claim 1, wherein the handgrip has two ends of different diameters, a first end having a diameter greater than that of the second end and a plurality of hex insertion bores of varying sizes formed therein, the second end having hex clipping troughs of varying sizes to couple respectively a hex wrench, the second end further being coupled with a hollow sliding cap.

3. A composite wrench kit as claimed in claim 1, wherein the handgrip and the sliding cap have respectively a plurality of stripe notations formed on an outer wall, the handgrip having an axial guiding trough on the second end and an anchor plate on a rear end of the guiding trough, the sliding cap having a latch hook on an inner wall slidable in the guiding trough to be stopped by the anchor plate.

4. A composite wrench kit as claimed in claim 1, wherein the coupling ring has two troughs on the inner wall opposing each other, two wedge flutes on two opposite outer sides and an ear on one end of an inner side, the handgrip having two bulged walls on the outer periphery opposite to each other.

5. A composite wrench kit as claimed in claim 1, wherein the first wrench housing is hollow and substantially annular having one side to receive a holding member, the holding member having a plurality of first insertion bores of varying size formed on an outer side, at least one latch spot on a upper side and a lower side of the outer wall to be confined by an inner wall of the first wrench housing, the coupling section of the first wrenching housing having a retaining section on an outer end to rest on one end surface of the wedge flute of the coupling ring.

6. A composite wrench kit as claimed in claim 1, wherein the retaining ring of the first wrench housing has an indented ditch on each of two opposite sides, the second wrench housing having a latch ridge on the inner wall corresponding to the ditch.

7. A composite wrench kit as claimed in claim 1, wherein the coupling section of the first wrench housing is engageable with a hanging hook, the hanging hook having an outer wall and an inner wall to form a slot therebetween that has an opening directing downwards, the outer wall having a bottom to couple with a clipping blade which is extended inwards to taper the opening, the inner wall having a wedge trough to couple with the coupling section of the first wrench housing.

8. A composite wrench kit, substantially as described and illustrated herein with reference to FIGS. 2, 3, 4, 5, 6, 7, 8, 9, 10, 11 and 12.
