At this time, due to the small magnetization, the magnetic repulsion of the mosquito will increase (according to the principle of magnetic force: the magnitude of the magnetic force is the ratio of the squared to the square), thereby providing The pawl 30 resets the force. Since the magnetic force of the magnetic member retreats much longer than that of the conventional spring, the ratchet wrench i of the present invention can maintain a normal operation after a long period of use of °. Referring to the figure of the first and the ninth, the magnetic member 4 of the present invention is composed of a magnet 41 and a housing 42. The housing 42 is made of a magnetically permeable material or a non-magnetically permeable material, thereby eliminating or reducing the magnetism of the magnet 41 to the shank 30 and the shank 1 。. The accommodating body 42 has a hole 乂 and a vent hole 44 located beside the hole 43 in parallel with the hole 43. The magnet 41 is inserted into the hole 43 of the accommodating body 42 in a tight fit manner, and the vent hole 44 is a duct for discharging the gas remaining in the hole 43 when the magnet 41 is inserted. The tenth view is another housing 42 in which the venting opening 44' is located rearward of the opening 43 and perpendicular to the opening 43. In addition, as shown in the eleventh figure, the outer end of the magnet 41" is located in the hole 43 of the receiving body 42, so that the shielding magnetic effect of the receiving body can be improved. Twelfth and tenth 3 is a ratchet wrench 2 according to a second preferred embodiment of the present invention, which is similar to the first embodiment except that the pawl 5〇 is located in the middle of the alcove& the two magnetic members 52 are opposite poles, in other words, The magnetic force is generated between the two magnetic members 7 52. When the multi-wrench 2 _ needle rotates, as shown in the twelfth figure, the end abuts against the concave chamber 51 and acts as a magnetic attraction force, The scoop is on the side wall, and the brother is from the mountain—it seems that you are still not green (2) to the mouth, and the silky red, 'the crotch part 53 is rotated with the ring tooth 55 of the driving member 54, or? Cap (not shown). When the ratchet wrench 2 counterclockwise causes two] 5" read the thirteenth figure shown 'the bolt (or nut) does not turn ' : ^ iS_ ^ claw 3 〇 back 'to make the 掣The tooth portion 32 of the claw 30 is separated from the driving member 20 from the unloading portion 22, and the magnetic attraction between the two magnetic members 4 提供 provides the force for resetting the 掣 掣 claw 30. There are also inventions using magnets in hand tools, such as the national patent certificate number 1224989 patent and the inventor's previous invention (application No. 94203657), which is the active neck and chute of the adjustable wrench. The magnets are arranged on the two sides, and the movable jaws are maintained in the center of the chute by the magnetic force. These two previous cases are completely different in structure and function from the case. 1270443 [Simple diagram of the diagram] The diagram of the first conventional ratchet wrench The first diagram is the schematic diagram of the second conventional ratchet wrench The first diagram is the schematic diagram of the third conventional ratchet wrench, and the fourth diagram is the fourth conventional ratchet Schematic diagram of the wrench, the fifth figure is a schematic diagram of the fifth conventional ratchet wrench, and the sixth figure is the read state of the first preferred embodiment of the present invention when the wrench is turned smoothly; #图'显10 is 拓七图A partial cross-sectional view of a first preferred embodiment of the present invention, showing a state of a dry hand and a clockwise rotation; FIG. 8 is a bottom view of the magnetic member of the first preferred embodiment of the present invention; 9-9 is a cross-sectional view of the line; f is a schematic view of the second magnetic member; the eleventh is a schematic view of the third magnetic member; __ shows a second embodiment of the second preferred embodiment of the present invention The partial cross-sectional view shows the state when the hand frequency is rotated, and __ shows a partial view of the second preferred embodiment of the present invention, showing the state when the hand is rotated counterclockwise. 1270443 [Main component symbol description]
