New description: [New technical field] This creation is about a positioning structure of a toggle device, especially for lotus use--a positioning device for a ratchet wrench in a ratchet wrench, wherein the ratchet wrench is equipped with A toggle device is used to move a ratchet block to change the yaw direction or angle to achieve the direction of the shift operation. [Prior Art] The structure of a general ratchet wrench is a head group formed at one end of a rod body, and a dialing device is provided for shifting the angle or direction of a ratchet block disposed in the head, according to which The effect of changing the direction of operation. Further, the dialing device is provided with a protruding shaft portion, and the shaft portion is radially assembled with a pressing unit composed of a spring and a positioning post. When the shaft portion and the pushing unit are assembled in the head of the rod body, the positioning column of the pushing-unit protrudes and abuts against the surface of the ratchet block. Rotating the toggle device allows the positioning post to rest at different positions of the ratchet block, so that the ratchet block can be swung in different directions or angles. ^ It can be seen from the above description that the dialing device only uses the pushing unit to contact the ratchet block to achieve the positioning effect, so in the case of improperly operating the dialing device, the positioning between the pushing unit and the ratchet block is easily caused. Invalid' and the toggle device is disengaged from the shaft of the ratchet wrench. [New content] In view of the disadvantages of the prior art that the ratchet wrench does not have a structure for fixing the dialing device, which causes the dialing device to fall off, the present invention provides a positioning structure, in particular, a ratchet wrench. The moving device positions the 5 M311533 structure. The purpose of the present invention is to provide a ratcheting device locating device positioning structure that includes a limiting slot and an elastic limiting component, wherein the limiting slot is formed on the surface of the shaft of the dialing device, and the elastic limit The component group is disposed between the shaft portion and a pivot for pivoting a ratchet block, and one side of the elastic limiting component is embedded in the limiting slot, and the other side is opposite to the pivot axis, thereby achieving the dialing The moving device is limited by the elastic limiting element and does not come out. Another object of the present invention is to provide a ratchet wrench toggle device I positioning structure, which comprises a limiting slot, a slot and an elastic limiting component, wherein the limiting slot is formed on the axis of the dialing device a surface of the portion, the recessed groove is formed in the inner wall of the hole of the actuating seat, and the elastic limiting member is disposed in the limiting slot and the recessed groove, thereby achieving the limitation of the toggle device by the elastic limiting component The effect of the escape. The above is a further preferred embodiment according to the purpose, function and structural configuration disclosed by the present invention, and is described in detail in conjunction with the drawings. [Embodiment] > Referring to Fig. 1, a ratchet wrench (1〇) has a rod body (12), and one end of the rod body (12) forms a head (14), and A dialing device (2 〇) is disposed in the head (14). I wish to refer to the W苐2 diagram. The head (14) has an accommodation space (16) and a toothed portion (18) on the inner wall surface. Please refer to Figures 2 and 3 for an actuator (30). A portion (32) and an actuator head (34) are included, and the actuator head (34) protrudes from the seat portion (32). Further, a shaft hole (36) is defined in the axial direction of the seat portion (32), and an opening (38) 6 M311533 is defined in the side surface. A ratchet block (40) is disposed in the opening (38), and a pivot (42) extends through the opening (38) and the ratchet block (40) such that the ratchet block (4〇) and the actuating block Block (3〇) combined. The dialing device (20) includes a dialing portion (22), a shaft portion (24) and a pushing unit (26). The g-helmet portion (22) may be a circular disk-shaped body, the shaft portion (24) is a cylinder and is formed on the side of the dial portion (22), and the shaft portion (24) is vertically aligned. Moving part (22). The pushing unit (26) includes a spring (27) and a positioning post (28) and is assembled in the radial direction of the shaft portion (24), and the positioning post (28) protrudes from the surface of the shaft portion (24). The shaft portion (24) of the dialing device (20) is disposed in the shaft hole (36) of the actuator (30), and the positioning post (28) can be placed against the surface of the ratchet block (40). The combination of the dialing device (20), the actuating seat (30) and the ratchet block (4〇) is mounted in the accommodating space (16), and the movable seat can be assembled by a positioning ring (19). 30) Between the head (14), the actuator (30) is not released. Further, the tooth portion (44) of the ratchet block (40) faces the tooth portion (18) on the inner surface of the head portion (14). Referring to Fig. 4, a limit groove (50) is formed on the surface of the shaft portion (24). Referring also to Figures 3 and 4, an elastic limiting member (60) is disposed between the shaft portion (24) and the pivot shaft (42), and the elastic limiting member (60) is laterally embedded in the limit. The groove (50) is formed on the other side with an arc portion (62) resting on the surface of the pivot (42). The position of the limiting slot (50) can be adjacent to the dialing portion (22). Referring to Fig. 5, the limiting slot (50) is located away from the dial portion (22) adjacent to the other end of the shaft portion (24). The structure and arrangement of the elastic limiting member (60) are the same as those described above, and will not be described again. Since the elastic limiting member (60) is disposed inside the ratchet wrench (10), the elastic limiting member (60) can provide a blocking function when the M311533 is moved in the disengaging direction. The dialing device (20) is restricted from coming out. Referring to FIG. 6, another embodiment of the present invention has a recessed groove (37) at a wall surface of the shaft hole (36) adjacent to the bottom portion, and a surface of the shaft portion (24) is provided with a - limiting groove (50). . An elastic stop member (60), such as a C-shaped buckle, is received in the limit groove (50) and extends into the shaft hole (36) along with the shaft portion (24). When the limiting slot (50) is opposite to the slot (37), the elastic limiting component (60) is expanded, so that the elastic limiting component (60) can be embedded in the limiting slot (50) and the embedded In the groove (37), the dialing device (20) is thus restricted by the elastic limiting member (60) and cannot be removed. The above embodiments are merely illustrative of the techniques and effects of the present invention, and are not intended to limit the present invention. Anyone skilled in the art can modify and change the above embodiments without violating the technical principles and spirit of this creation. Therefore, the scope of protection of this creation should be as listed in the patent application scope mentioned later. .
