The driver shaft 2 of the different working end 20 can be easily replaced (the fastening structure is a conventional technique, so it will not be described again), and the outer surface of the driver shaft 2 is covered with an insulating plastic 20, which can be used for holding. When the ratchet driver of the present invention is used to lock the object, the switching button 38 only needs to be pushed to one side, so that the switching button 38 is embedded in one of the positioning slots 305 of the base 30. (As shown in the seventh figure), when the switching button 38 is pushed to one side, the switching button 38 drives the linkage seat 31 provided in the base body 30 to move along with it, and the linkage seat 31 drives the two latching blocks 32. And 33 moves accordingly, wherein the ratchet teeth 320 of one of the latching blocks 32 are engaged with the ratchet teeth 370 of the ratchet wheel 37 (as shown in the eighth figure), and the bottom of the latching block 32 is resisted by one end of the elastic piece 35 The end 350 is elastically resisted, and the upper portion of the latching block 32 is held by the retaining body 314 at one end of the connecting base 31, and the user holds the grip 1 to rotate. And the screwdriver shaft 2 rotates together with the ratchet wheel 37. When the handle 1 rotates clockwise, the upper part of the latching block 32 is blocked by the blocking body 314 of the connecting seat 31, and cannot be rotated downward, so that the card is rotated. The ratchet teeth 320 of the block 32 and the ratchet teeth 370 of the ratchet wheel 37 are firmly engaged with each other, so that the ratchet wheel 37 is braked by the latching block 32 and cannot be rotated (as shown in the eighth figure), and the driver shaft 2 can be Performing a clockwise rotation locking action on the object; when the user directly holds the handle 1 to reverse the wrist to the positive direction (ie, rotates counterclockwise), the ratchet 37 rotates in the opposite direction (ie, rotates counterclockwise) And pushing the card block 32, the card block 32 is pivoted outwardly with the support shaft 321 as an axis (as shown in FIG. 9), and the bottom of the card block 32 is pressed against the end of the elastic piece 35. The end 350 is in an elastic compression state, and the elastic deformation of the elastic piece 35 causes the latching block 32 to generate a jumping state when the ratchet wheel 37 rotates in the reverse direction. When the handle 1 is rotated in the reverse direction, the handle 1 can be Forming an idling state, so that the user can hold the handle 1 and perform a reciprocating rotation quickly, so that the driver shaft 2 rotates rapidly in the same direction. The action of locking the object; when the object is to be loosened, the switching button 38 of the ratchet switching device 3 at the rear end of the handle 1 has to be moved to the other side, so that the switching button 38 is embedded in the base 30. In another positioning slot 305 (as shown in FIG. 10), the switching button 38 drives the linkage 31 to move to the other side, and the linkage 31 drives the two latching blocks 32, 33 to move. The latching block 32 that meshes with the ratchet 37 is disengaged from the ratchet 37, and the ratchet 330 of the other latching block 33 engages with the ratchet 370 of the ratchet 37 (as shown in FIG. 11). The bottom of the 33 is elastically resisted by the abutting end 351 of the other end of the elastic piece 35, and the upper part of the latching block 33 is held by the retaining body 314 of the other end of the connecting seat 31, and the user holds the grip 1 to rotate counterclockwise. And the screwdriver shaft 2 is rotated together with the ratchet wheel 37. As described above, the upper portion of the latching block 33 is blocked by the retaining body 314 of the connecting base 31 and cannot be rotated downward, so that the spine of the latching block 33 is reversed. The teeth 330 and the ratchet teeth 370 of the ratchet wheel 37 are firmly engaged with each other, so that the ratchet wheel 37 is braked by the latching block 33 and cannot be rotated, and the screwdriver shaft 2 can be When the user holds the handle 1 in the reverse rotation (ie, rotates clockwise), the ratchet 37 also rotates in the opposite direction (clockwise rotation) and pushes the card. In the block 33, the latching block 33 is pivoted outwardly about the pivot axis 331. The bottom of the latching block 33 presses the abutting end 351 of the other end of the elastic piece 35 in an elastic compression state, and the elasticity of the elastic piece 35 is achieved. When the ratchet block 33 rotates in the reverse direction of the ratchet wheel 37, a bounce state is generated, so that when the handle 1 is rotated in the reverse direction, the handle 1 can be in an idling state. Thus, with the ratchet switching device 3 of the present invention, The user can hold the handle 1 and perform a reciprocating rotation quickly, so that the driver rod body 2 is quickly rotated in the same direction for the work of locking or unscrewing the object without loosening the grip handle 1 It can prevent objects from falling when locked, and achieve the effect of fast operation.
