[Prior Art] According to the 'the ratchet wrench on the market, it can be divided into one-way drive or two-way drive type. However, the two-way type ratchet wrench can be used to switch the steering due to the external setting. The disadvantages of replenishing materials (IV) and high manufacturing costs exist. As shown in FIG. 7, the unidirectionally driven ratchet wrench structure has a head portion 6 located at the top end of the handle 6, and the head portion 61 has an accommodation space 62 for use. The ratchet wheel 63 is received, and a slot hole 64 is defined in the wall surface of the space 62, and the (4) block 6 5 and the spring 6 6 are mounted in the slot hole 64 in sequence. The moving block 65 is displaced by the moving block 65 to provide a ratcheting of the ratchet 6 3 . However, if a ratchet 6 3 having a small excess tooth shape is used, a larger slot 6 4 square is required. The engine block 6 5 is sufficient: the shifting space is not applicable to the ratchet with a small number of teeth. ^ Figure 8 is a (four) alternative type of one-way driven ratchet wrench, 4' The hole 7 is used for accommodating the slot 5 of the movable block. The through hole 7 7 is provided for the spring 7 6 to provide sufficient displacement space for the ram block 75, but It will increase the difficulty of assembly. 3 M438351 _ , 2012/06/26 Correct the replacement page degree, and the drilling process is time-consuming, so it can not be effectively reduced. In view of this, how to solve the above problem is the creation To solve the first problem, therefore, the present case is the creator of constantly trying to come up with after a test for, has finally produced this creation. [New content] The main purpose of this creation is to provide a ratchet wrench with an improved structure, which has a simple structure and is easy to manufacture, and can effectively reduce the cost of manufacturing φ. For the purpose of the foregoing, the present invention provides a ratchet wrench having an improved structure, comprising: a body having a head end and a grip, the head end having a receiving groove, and the peripheral wall of the receiving groove is further recessed and a ratcheting chamber; a ratchet wheel disposed in the pocket; the outer peripheral ring of the ratchet is provided with a ratchet portion composed of a plurality of ratchet teeth, and an actuating portion is formed at a center position of the ratchet; , the pivoting member is disposed in a direction of the ratchet portion of the ratchet wheel, and the latching member is formed with a blocking portion on a side opposite to the latching portion; The elastic member is disposed in the concave chamber, and one end of the elastic member is elastically abutted against the peripheral wall of the concave chamber, and the other end is elastically abutted against the blocking portion of the braking member, so that the engaging portion of the braking member is unidirectionally clamped to the ratchet On the ratchet. Further, the ratchet portion of the ratchet is formed by a plurality of arcuate ratchets extending in the longitudinal direction. Further, the actuating portion is a class hole penetrating the ratchet wheel, and the 4 M438351 2012/06/26 modified replacement page is sequentially formed on the inner wall of the δ Xuan actuating portion, and the first set having one of different inner diameters is formed. - Interface and a second set of interfaces. Further, a pin hole is defined in the brake member, and a positioning pin passes through the pin hole through the head end of the body to pivot the brake member to the recess. Of course, this creation is tolerated on certain parts or arrangements of parts, but the selected embodiments are described in detail in this specification. [Embodiment] Referring to Figures 1 to 3, the present invention provides a ratchet wrench having an improved structure, which is mainly composed of a body cymbal, a ratchet 2 丄, a brake member 3 1 and an elastic member 4 1 , wherein: The body 1 1 has a head end 丄 2 and a handle 13 extending from the opposite end of the head end 丄 2, and the head end i 2 of the body 1 is integrally formed with an outer space by dewaxing casting. The groove 12 1 is connected to the groove 12 1 , and the groove 1 2 1 has an alcove 1 22 communicating with the 5 hole receptacle 1 2 1 on the peripheral wall of the handle 13 . The ratchet 21 is received in the pocket 121 and looped by a retaining ring 24 to prevent the ratchet 2 1 from coming out of the pocket i 2 , and the outer peripheral ring of the ratchet 2 is provided with a majority The ratchet portion 22 is formed by the extended arcuate ratchet, and an actuating portion 23 is formed at a central position of the ratchet 21 for contacting the workpiece to be locked. In the embodiment, the actuating portion 23 is a class hole penetrating through the ratchet wheel, and the inner wall of the actuating portion 23 is modified according to M438351 2012/06/26.

The 5th brake member 3 1 is disposed in the recess 丄 2 2 of the body i 丄 end i 2 'The brake member 3 1 is provided with a pin hole 3 2, and a positioning pin 3 3 is passed through the body! The head end 2 of the crucible passes through the pin hole 3 2 , and the braking member 3 1 is pivoted to the recess 1 2 2 so that the braking member 3 can be rotated by the positioning pin 3 3 The swaying action, and the braking member 3 is convexly disposed toward the ratchet portion 22 of the ratchet 2 1 - a latching portion 34, and the braking member 31 is formed on the opposite side of the engaging portion 34 a retaining portion 3 5 is formed, and the retaining portion 3 is formed on the side of the latching portion 3 4 and the retaining portion 35 to form a limiting portion 3 protruding toward the bottom edge of the recessed chamber 1 2 2. The member 4 is disposed in the recess 2 2 of the head end 1 of the body 11. In the embodiment, the elastic member 4 is formed by a compression spring, but may also be a torsion spring or other elastic. The elastic member 41 is replaced by one end of the elastic member 41 against the peripheral wall of the recess chamber 2, and the other end is elastically engaged with the broadcasting portion 3 of the brake member 3 1 , and thereby the braking member 3 is thereby 1 can be pivoted toward the ratchet portion 2 2 of the ratchet 2 1 by the top support of the mysterious elastic member 4 1 and unidirectionally clamped to the ratchet portion 2 of the ratchet 2 2 by its engaging portion 34 2 on. Then please refer to Figure 4, when the operator uses the ratchet 2 1 to actuate 6 2012/06/26 to correct the replacement page 3 2 3 of the first set of interfaces 2 3 1 or the second set of interfaces 2 3 2 fit in one - When the workpiece is to be locked on the workpiece (not shown), when the operator swings the ratchet wrench counterclockwise, the latching portion 34 of the braking member 3 1 will be ratcheted with the ratchet 2 1 when & The portion 2 2 forms a state of engagement with each other, and thereby the operation of the workpiece to be locked fitted in the ratchet 2 i actuating portion 23 can be synchronously driven for locking or loosening. Conversely, when the ratchet wrench is swung clockwise, the ratchet 2 on the ratchet 2 will be pressed against the ratchet of the brake member 31 as shown in Fig. 5. 3 4 'and forcing the brake member 3 to swing and shrink the elastic member 4 i, thereby releasing the card state between the engaging portion 3 of the braking member 3 and the ratchet portion 2 of the ratchet 21, In one case, the ratchet wrench can be swung clockwise without the ratchet 2 带. In addition, since the ratchet wheel 2 1 of the wood creation has a circular arc shape, a deflection adjustment operation can be performed in the pocket 1 1 1 in use, and when the ratchet 2 1 is deflected to the actuation portion 2 3 and the When the latching portion 3 of the brake member 3 is opposite and cannot be sprayed with the ratchet portion 22, the brake member 3i is biased by the elastic member 41 as shown in FIG. The outer swing ▲' and the stop portion 36 abut against the bottom edge of the recess 丄2 2 to limit the swing angle of the brake member 31, so that the elastic member 4 does not work due to the brake member 3 1 If the angle of the swivel is too large, the contact with the blocking portion 35 is lost, causing the elastic member 4 1 (4) to escape in the recess 1 2 2 .
