The present invention relates to a fast switch hand tool, more particularly to a fast switch hand tool having switch means.
Referring to Taiwan Patent No. 155346, discloses a prior wrench comprising a ratchet included on two ends thereof and provided for driving a screw. However, the prior wrench can only drive two standards screws and not provide the effect of fast poking. It's not convenient for a user to carry on several kinds of wrenches.
It is therefore the purpose of this invention to provide a fast switch hand tool, which comprising a base board, a plate, a shell, a cover, a driving shaft disposing in the said members and connecting to all of them, a switch means mounting on the base board and provided for the driving shaft the effect of driving to switch the direction, and a fast poke member disposing on the driving shaft and provided the effect of fast poking.
Other objectives, advantages, and features of the invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.

A space 11 is formed on an end of the base board 10, a hanging hole 12 is formed on another end thereof, a connecting portion 13 is defined between the space 11 and the hanging hole 12, and the two inside walls of the space 11 both includes a protrusion 14 and a slot 15. The connecting portion 13 is a thinner plate than the base board 10, a plurality of combining hole 16 and a through portion 17 are formed on the connecting portion 13, and a recess 18 is extended from a side of the space 11 to the connecting portion 13.
The plate 20 presses on the connecting portion 13 of the base board 10 and disposes in the combining holes 16 via a plurality of fixed element 21. A through hole 22 and three coupling holes 23 are formed on an end of the plate 20.
The shell 30 is U-shaped and includes a base 31 and a top 32. Two through holes 33 are respectively formed on an end of the base 31 and the top 32, and two concavities 34 are respectively defined on the side of another end thereof. A plurality of fixed hole 35 and three coupling holes 36 are formed on the base 31. The shell 30 couples to the base board 10 via the fixed elements 21 of the plate 20 fixing in the fixed holes 35 through the combining holes 16 of the base board 10.
The cover 40 includes a pivot portion 41, a compartment 42 and a poke portion 43. The pivot portion 41 which disposing in the shell 30 provides a pivot hole 44 corresponding to the through hole 33, and a concave portion 45 which is formed on a side of the pivot portion 41 exactly installs the fast poke member 70. A protrusion 46 is formed on the poke portion 43 corresponding to the concavity 34 of the shell 30, and the outer surface of the poke portion 43 is hollow such that it's easy to poke.
The driving shaft 50 which respectively through the through hole 22 of the plate 20, the through holes 33 of the shell 30 and the pivot hole 44 of the cover 40 disposes in the space 11 of the base board 10 and respectively hooks the through hole 22 of the plate 20 and the through holes 33 of the shell 30 via a C-clip. A driving hole 51 is defined on an end of the driving shaft 50 and a driving head 52 is formed on another end thereof. Further, the driving hole 51 exposes from the plate 20 and the driving head 52 exposes from the shell 30. A ratchet 53 which mounts on the driving shaft 50 near the driving hole 51 receives in the space 11 of the base board 10, a holding portion 54 which is situated on the driving shaft 50 where the shell 30 is disposed on, is embossed, and the fast poke member 70 retains on the holding portion 54 by means of installing between the base 31 and the cover 40.
The switch means 60 includes a poke member 61, an elastic portion 62, a ball 63, two poke blocks 64 and two elastic elements 65. Two pawls 611 which are formed on the two ends of the poke member 61 respectively dispose to the slots 15 of the base board 10. A retaining portion 612 is defined next to the two pawls 611 and having three concavities. A protruding block 613 is opposite to the retaining portion 612, and two recesses 614 are respectively formed on the two sides of the protruding block 613. A protruding portion 615 which is defined on the upper surface of the protruding block 613 exactly engages to the coupling hole 23 of the plate 20 and the coupling hole 36 of the shell 30. The elastic portion 62 receives in the recess 18 of the connecting portion 13, and the ball 63 receives between the elastic portion 62 and the retaining portion 612. The two poke blocks 64 dispose in the two recesses 614 on the two sides of the protruding block 613. An extending portion 641 which is formed on an end of the poke block 64 pivotally disposes to the coupling hole 23 of the plate 20 and the coupling hole 36 of the shell 30. An engaged portion 642 formed on another end of the poke block 64 exactly engages with the ratchet 53 of the driving shaft 50. The elastic element 65 mounts on the protrusion 14 of the base board 10 and pushes the poke block 64.
