The wheel is equipped with a tilting member to selectively control the single-handed wrench. The ricket effect is used to solve the problem that the previous need to be repeated and the card is engaged and then rotated. In order to improve the manual == the sleeve wheel system is a single size specification, == part, but this design will make the ratchet wrench only the size - so the user must prepare a variety of different rules; the wrench can meet different Operational requirements, this will increase the consumption of this, and also increase the weight of the toolbox' does not meet the development direction of the existing hand tools, which is more standardized and easy to carry. In recent years, the ratchet wrench with replaceable sleeve wheel has been developed. In the figure, the ratchet wrench is formed with a wheel groove (12) in the head (11) at both ends of the trigger (10), and an outer f ratchet is provided in the wheel groove (12). The wheel (20), the sleeve f nut, and the bottom edge of the wheel groove are opened to have a flange for the fitting wheel (other) to be abutted (120) 4 the head (11) is adjacent to the wheel groove (12) The circumference of the rod (1〇) is raised into a trough (13), and the trough (13) is accommodated - with a spine 3 201038365 teeth (26) The piece (25) is for rotating the control sleeve wheel (2〇), and the head (11) is formed with a horizontal socket (14) on the inner wall surface of the dial (13), and the socket (14) is inside. The push rod (29) and the elastic member (29〇) are provided with a back edge of the tilting member (-25), and the head portion (the top surface of the ιυ is formed with a recess at the corresponding dial (13) ( 15;, a cover sheet (16) for restricting the swaying member (25), wherein the cover sheet (16) is formed with a curved shift groove (I?) at the proximal wheel groove (12). And the cover sheet (16) is formed on a side edge of the shifting groove (17) with a downwardly-faulted release groove (18), and the top surface of the tilting member (25) has a through-draw (17) a push rod (28) for the user to control the position of the swaying member (25), and the middle portion of the opposite surface of the arranging wheel (2 〇) and the raking member (25) is formed with a limit ring groove that can be relatively inserted And the limiting protrusion (27), and when the user pushes the lever (28) to actuate the moving member (25) to move along the release groove (18), the limiting protrusion of the foregoing moving member (25) can be 27) Separate from the limit ring groove (22) of the sleeve wheel (2〇) The set wheel (2()) can be taken out to replace the different specifications of the sleeve wheel (20). , \ Θ But in actual use, there are some problems, such as the first, second, shown The swaying member (25) is embedded in the limiting ring groove (22) of the splicing wheel (20) by the limiting protrusion (27) of the middle section, and the urging member (25) is affected by the processing precision. The bottom edge cannot be effectively attached to: the surface of the groove (12) (12〇), so the tilting member (25) is suspended and passes through the push rod (28) that passes through the cover sheet (16). To move the swaying member (25), since the user pushes the push rod (28) with a finger, the urging point is easy to form a urging arm with the ejector pin (29) of the top abutting swaying member (25). Thus, the phenomenon that the actuating member (25) is tilted toward the pusher (28) force-applying side 4 201038365 [as shown in the second figure], thereby causing the limit projection (27) of the tilting member (25) The limit ring groove (22) of the sleeve wheel (2〇) causes the problem of jamming and abrasion, which affects the convenience of replacing the sleeve wheel (2〇), and even shortens its service life; (2〇) limit ring groove (22) and tilting (25) The limit projections (27) are located in the middle section, so when the two are combined, they are affected by the processing difficulty, and the ratchet (2) and the ratchet (21) of the tilting member (25) (26) ) The number and area will be reduced, so that it is easy to cause gaps and inaccurate problems in the tooth surfaces of the ratchet (26) and the ratchet (26) (21) of the sleeve wheel (20), resulting in a sleeve wheel. (2G) and the ratchet (21) of the engine (25) (26) The phenomenon of tooth jump or chipping occurs due to the fact that the click is not correct, so there is a problem of insufficient torque resistance. In addition, the flap (25) is restricted by the cover sheet (16) so as not to fall off when the sleeve wheel (20) is replaced. In order to restrict the flap (25), the shift groove (17) cannot be formed into an open shape. The diameter of the pusher (25) pusher (28) will be limited, affecting its structural strength and service life. Further, if the shift groove (17) of the cover sheet (16) is changed to an open shape in order to increase the diameter of the push rod (28), the tilting member (25) may be removed after the pull-out wheel (2) is taken out. Since the scale is no longer restricted, it will cause the push column (29) and the elastic member (290) behind the swaying member (25) to be disengaged, and the pusher column (29) and the elastic member (29 〇) The volume is not large, and there are problems of missing components, resulting in inconvenience in replacement and use. In view of this, the present inventors have intensively discussed the problems faced in the replacement structure and operation of the above-mentioned existing ratchet wrenches, and actively seek solutions by years of experience in research and development and manufacturing of related industries, 5 201038365 After long-term efforts The research and development finally succeeded in developing a ratchet wrench replacement structure, which can solve the inconvenience and trouble of the structural strength of the existing ratchet wrench and the loss of components.

The clickability of the cassette is reduced, and the occurrence of the jump or the collapse is reduced, so that the torque resistance value can be increased. 3, the mobility surface · According to the previous description, because the limit = moving parts (10) adjacent to the top edge, it can be increased, so that not only can increase the number of 掣 掣 * (71), and because of its no-fault The authenticity of the card can be confirmed. Port A: In addition, due to the cover sheet (56), the push-pull is 73) mu - so the connecting rod of the push piece (75) can be enlarged (the diameter is improved compared with the formula). The moving parts (70) and the closing wheel (6〇) 1 are effective, and the problem of reading the teeth is invisible, and the life of the (4) is extended invisibly. 5. The components are not lost: in addition, although the gap (57) is open Shape, and make the swaying piece (7 pieces () of the plucking wheel (6 〇) when there is a possibility of escaping, but by 掣 ^ change the set with a push piece ("大其赵积, because 11 201038365 lost" And the push rod (78) and the elastic member (79) are disposed in the fixing seat (76), so when the tilting member (7〇) falls behind, the smaller pushing rod (78) and the elastic member ( 79) No arbitrarily detached, so there is no problem of missing components, and the convenience of replacement can be improved. In summary, the present invention has many practical values as described above, and thus the present invention is indeed a novel and progressive creation.
