如第7圖所示，為習用之棘輪板手結構，A 於握柄9 0頂端之頭部9 1，且該頭部9 !係具 空間9 2而可供-棘輪9 3容置，並於該容置空間^置 壁面上係設有一穿孔9 4，而於該穿孔94中則依序= 有一掣動塊95、一彈簧96以及一鎖固座97，並 彈簧9 6係用以頂撐該掣動塊9 5，而使該掣動塊9 5 = 得與該棘輪9 3之外周相互嚙合’並藉以提供該棘於^ 一單向卡掣之功能。 由圖中可見，此種習用之棘輪扳手於製造時，係直接 於該容置空間9 2之壁面上貫設有該穿孔9 4，然而，如 此一來，勢必會破壞該頭部9 1之結構強度，而導致該棘 輪扳手於受較大之施力時，會有從該頭部9 1折斷而損壞 之情形發生。 丄处秫輸孜乎之棘輸y J田於受到該掣動塊9 5所提供之單向卡掣作用，而使該棘輪9 3僅具有一固定 之可旋轉方向，因此並紐依照工作需求，而隨意變換二 輪9 3之可運轉方向，故，上述習用之棘輪板手仍有 完善，而尚有需要改進之處。 【發明内容】 5 200944334 本發明目的之一，在於提供一種棘輪扳手，其具有結 構簡單’並兼具有良佳之結構強度，而可降低製造成本並 且延長棘輪扳手之使用壽命者。 本發明目的之二，在於提供一種棘輪扳手，其具有可 依照工作需求之不同，而隨意變換棘輪之可運轉方向。 為達前述之目的’本發明係提供一種棘輪扳手，其包 含有：As shown in Fig. 7, in the conventional ratchet wrench structure, A is at the head 9 of the top end of the grip 90, and the head 9 is provided with a space 9 2 for the - ratchet 9 3 to be accommodated, and A through hole 94 is disposed on the wall of the accommodating space, and in the hole 94, there is a swaying block 95, a spring 96 and a locking seat 97, and the spring 96 is used for topping. The ram block 9 5 is supported so that the sway block 9 5 = engages with the outer circumference of the ratchet 9 3 and provides the function of the unidirectional click. As can be seen from the figure, the conventional ratchet wrench is constructed to directly penetrate the perforation 94 on the wall surface of the accommodating space 92. However, in this case, the head 9 1 is bound to be destroyed. The structural strength causes the ratchet wrench to be broken and damaged from the head 9 when subjected to a large force.棘 秫 y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y However, the freewheeling direction of the second wheel 9 3 can be changed at will, so that the above-mentioned conventional ratchet wrench is still perfect, and there is still a need for improvement.

The inner diameter of the guide groove 7 is limited to: ', and the stroke of the shaft block 3 2 during sliding is effectively guided, and the end of the movable block 32 facing the receiving portion 14 is formed with a latch 4, and the The latching teeth 4 4 and the ring teeth 2 2 on the ratchet wheel 2 i correspond to each other such that the engine block 3 2 is supported by the elastic member 33, and the teeth 34 are unidirectionally cut. The ring gear 2 2 of the ratchet 2 1 has a pressure receiving surface on the latching teeth 3 4 3 6 ; The control member 41 ' is rotatably mounted in the % recess 416 of the active end 1 2 ' and has a groove 4 2 ' buckle on the circumferential surface of the control member 4 4 4 is embedded in the recess 4 2, and the control: 4: 3:: = the annular recess 16 in the receiving portion 14 abuts, the retaining ring 44 on the circumferential surface and the concave positioning The groove 46 is engaged with each other, so that one side of the ratchet 21 is abutted against the control member 41 by the upper edge of the abutment cylinder 4, and the control and the annular recess 16 are mutually exchanged. The abutting on the end face and the red is rotated by the #41, the pushing surface 47 is selected to be pressed against the pressure receiving surface 36 of the one of the latching members 31 of the one of the latching assemblies 31, and Forcing the squeezing block 3 2 to retract to release the latching action of the ratchet 2 i, and the control member 41 extends a switch portion 4 8 toward the trigger end 3 of the wrench body 1 The switch portion 48 extends rearward through the notch 8 and a plurality of positioning slots 4 9 are disposed inside the switch portion 48. The positioning slots 49 are respectively associated with the control apertures 8 i Pressing button 1 9 2 corresponds to each other; ❿

At the same time, the first closing lever 4 of the control member 4 1 is firstly biased so that the side of the switch portion 48 8 is latched by the limiting portion 1 8 2 of the missing portion 1 8 . At the same time, one of the positioning slots 4 9 of the switch portion and the button 1 9 2 of the control hole 1 8 1 are engaged with each other, so that the position of the control member 4 1 after the swing can be positioned, and The urging surface of the control member 41 is pressed against the pressing surface 36 of the swaying block 32A, and the swaying ghost 3 2 8 is forced along the guiding bow groove 7 7 A. Retraction, at this time, the other side is supported by the elastic member 33B, and the ring teeth 2 2 of the wheel / 2 2 are mutually slid to provide a one-way: when the ratchet wrench is swivel in the moving direction, Synchronization, job. The ratchet 2 1 has a polygonal hole-shaped actuating portion 24 = a locking or loosening operation, and since the other is: the volume is the guide (4) in the i7B, so when == the shell of the shell 3 2B is jammed When the wrench body 丄i is swung, 9 200944334, the swaying block 3 2 can effectively increase the radial branch of the swaying block 3 2 藉 by blocking the inner wall of the guiding groove 丄 7 Β The force, and in turn ^# the service life of the ratchet wrench. When the wrench body 1 1 is swung toward the other side, the swaying block 3 2 is affected by the reaction force generated by the wrench when the money is used, so that the ring gear on the ratchet 2 1 2 2 press the rocking block 3 ^

There is a φ and when the operator wants to change the traversable direction of the ratchet 2, as shown in the figure 4, only the portion 48 of the control member 41 is to be moved toward the other ^, so that the top of the control member 41 The push surface 47 is changed to the engine assembly 31 (four) moving block 32 Β the pressure receiving surface 36 ,, so that the operator can select the _ block 32 eight, 32 coffee ratchet 21 card shackle by adjusting the pushing of the control member 4 i Acting 'money to change the direction of operation of the ratchet 2 1 , and by the control member = the side of the closed portion 48 is affected by the one of the missing slots 18 丄 8 2 , and the control member 4 ; The positioning groove 4 9 200944334 on the switch portion 4 8 and the press button 9 9 are engaged with each other to fix the position of the control member 4 1 after the rotation. Then continue to refer to FIG. 5, when the control is performed When the positioning groove 49 at the intermediate position of the switch portion 4 8 is engaged with the push button 1 9 2, since the control member 41 is at this position, the pushing surface 47 does not move with any one. The pressure receiving faces 36A, 36B of the blocks 3 2A, 32B are in contact with each other, so that the ring teeth 2 2 on the ratchet wheel 2 1 are simultaneously jammed by the swaying blocks 32A, 32B on both sides, thereby The ratchet 2 1 is in a fixed state in which it is absolutely fixed and cannot be rotated in either direction. However, the embodiments described above are for explaining the present invention, and are not intended to limit the present invention, as shown in FIG. In another embodiment of the present invention, the actuating portion 24 disposed at the center of the ratchet 2 1 can also be a quadrangular column structure, so that the ratchet wrench of the present invention can be used for locking the four-corner hole. On the workpiece, it can be seen that the shape of the actuator that can smoothly drive the workpiece for locking or relaxing should be an equivalent embodiment of the invention. Φ And after detailed description above, the skill can be familiar with the present invention. It is obvious that the present invention can achieve the above-mentioned objects, and has already met the requirements of the Patent Law, and has filed a patent application. 11 200944334 [Simplified illustration of the drawings] FIG. 1 is a perspective exploded view of the present invention.
