And a smoothing section 25, wherein the smoothing section 25 has an outer diameter greater than an outer diameter of the ratchet section 24, and the ratcheting section 24 of the control 1 is comparable to the second jaw 5 The tooth 1 5 1 is relatively locked, so that the control ring 2 is configured to be in a fixed state, and the smoothing section 25 of the control ring 2 1 can be used to push the two; K1 5 to release the spine with the control ring 2 1 The palm portion of the tooth segment 24 is in a fixed state, and a contracting neck portion 26 and a positioning recess portion 27 are formed in a predetermined position from the bottom to the top of the inner wall surface of the control ring 2 1 . / The trigger 3 1-end is provided with a through hole 3 2, and the trigger 3 1 is provided with a hole 3 2 (4). The control ring 2 R is connected to the end 2 2 The two fixing pins 3 3 are respectively disposed in the triggering groove 3 i and the positioning groove 23 of the connecting end 2 2 , so that the trigger 3 can be connected with the control ring 21 and integrated with each other. Gearing. The top column 43 is disposed in the inner wall surface of the control ring 2, and the control ring 2 i is movable along the top column 4 - up and down. In the embodiment, the top column 4 1 is downwardly extended to form a bottom engraving 2 ′ and the top post 4 1 is fixed to the bottom surface of the u-axis of the driving head by the base 42 , and a protrusion is further protruded on the base 42 Corresponding to the reading portion 42 1 at the bottom end of the valley portion 14 to ensure that the top pillar 4 i is fixed to the bottom surface of the shaft hole 13 of the driving head 1 1 by its 201121718 base 4 2 , the base 4 thereof The end portion of the second portion of the receiving portion X 2 and the end portion of the receiving portion X 4 can be used to block the edge of the claw 1 5 to prevent the two claws 15 from coming out of the receiving portion 1 4; The top end of the top post 4 1 passes through the connecting end 2 2 of the control ring 2 并 and is exposed outside the through hole 3 2 of the trigger 3 1 to form a pressing portion 4 3 for the user. The pressing portion 43 is used as a fulcrum, and the force is applied to move the trigger 3 1 upward relative to the driving head 丄2, and at this time, the trigger 31 moves synchronously to move the control ring 2 1 up and The smoothing section 2 5 of the control ring 2 1 is movable to be associated with the second jaw 5, relative position ', so that the two jaws 5 can be pushed back by the smoothing section 25 to release the locking state with the ratchet section 24 of the control ring 2 1 , and the top pillar 4 The column of the column 1 is provided with a perforation 44, and the positioning block 45 is disposed in the opposite direction of the perforation 44, and the second positioning block 45 is provided with a second The elastic member 46 is further provided with a third elastic member 47 between the base 42 and the control ring 2 1 , and the second elastic member 46 is provided for the two positioning blocks 45 to The control ring 2 is in the direction of the inner wall surface of the control ring 2, and when the ratcheting section 2 4 of the control ring 2 1 and the molar 151 of the pawl 15 are oppositely locked to form a fixed state, the second positioning block 4 5 The control card 2 1 has a positioning function, and the control ring 2 i is synchronously driven by the trigger 3 i. When the card is moved up and the card is fixed, the card is in a fixed state, and the card is corresponding to the positioning recess 27 of the inner wall of the control ring 2 The same can be provided Position the player. 201121718, as shown in Figures 3 and 4, for displaying the state when the ratchet section 2 4 of the control ring 2 1 and the molar 1 1 1 of the two jaws 15 are mutually engaged. The driving head 丄i is fixed to the trigger 3丄, and the third elastic member 47 between the base 4 1 and the control ring 21 is in a compressed state, and the two positioning is performed. The block 4 5 corresponds to the card in the positioning recess 26 of the inner wall surface of the ring 2 1 , and the elastic member provided by the second elastic member 46 for bucking the two positioning blocks 45 is larger than the first 3. The returning elastic force generated by the sexual component 47, and thereby causing the control ring 2 to be clamped at a position fixed to the two jaws 15 so as to be in a fixed state. The wrench is capable of performing a large force application. While the user holds the trigger 3 1 by hand and applies the force to move the trigger 3 2 upward by using the top portion 4 1 pressing portion 4 3 as a fulcrum, 'when the applied force is greater than the second elasticity When the spring provided by the member 46 is resistive, the singapore positioning block 45 is forced to retract and the positioning of the control ring 2 i is released, and thus the trigger 3 1 can drive the control ring 2 2 relative to The drive head worker moves up. At this time, as shown in FIG. 5 and FIG. 6, when the control ring 2 is moved up relative to the drive head 11, the smoothing section 2 of the control ring 2 will be Pushing the two jaws 15 to compress the two first elastic members 26 and then moving back ' and thereby releasing the two teeth 5 of the second jaw 5 and the ratchet segment 2 of the control ring 2 1 4 is in a fixed state, and when the contracted neck 26 of the inner wall surface of the control ring 2 is relatively moved to a position opposite to the two positioning blocks 45, the two positioning blocks 45 are topped against the The inner wall surface of the control ring 2 1 is contracted on the neck portion 26 to position the control ring 2丄, and since the control ring 21 is not fixed by the latch of the two jaws 15 in 201121718, the trigger is 3 1 can be rotated relative to the driving head i to perform a fast rotation of the author. Furthermore, when the user wants to return the control ring 2 to a fixed state again, the user only needs to press the trigger 3 i and overcome the elastic force provided by the second elastic member 46. Forcing the two positioning blocks 45 to retract to release the positioning effect, and when the control ring 2 1 smoothing section 25 moves downward from the position opposite to the two jaws 15 , the two jaws i 5 can be subjected to The first elastic member 16 is supported by the ratchet segment 24 of the control ring 2 1 and is restored to a fixed state as shown in FIG. 3 . It can be seen from the above description that the two jaws 15 of the present invention are respectively supported by the two first elastic members 26 so that the teeth can be directly locked to the control ring. The ratchet segment 2 of the 2 1 can provide a relatively accurate fixing effect, and the wrench provided by the invention has the characteristics of simple structure, and thus can have better structural strength, and is easy to manufacture and assemble. The advantage of being relatively inexpensive, and the invention is also relatively simple and fast in operation, and therefore can be quite convenient in use. The disclosure of the above-described embodiments is intended to be illustrative of the present invention and is not intended to limit the scope of the invention. From the above detailed description, it will be apparent to those skilled in the art that the present invention achieves the foregoing objects and is in accordance with the provisions of the Patent Law.
