New description: [New technical field] This creation is related to a wrench', especially a one-way ratchet wrench. [Prior Art], according to the first figure, is a cross-sectional view of a conventional one-way ratchet wrench. The head position of the conventional one-way ratchet wrench 10 defines a chamber 11 and is worn. A perforation 12 is provided, and a recess 13 is recessed in the direction of the grip on the inner wall m formed by the chamber U, and the half-moon stop block 14 and the spring 15 are placed, and then the perforation 12 is A ratchet member 16 is disposed therein, wherein the ring side of the ratchet member 16 is a first ratchet surface 161, and one side of the stop block 14 is fastened to the inner side surface 131 formed by the recess 13 The other side is a second ratchet surface 141, and is engaged with the first ratchet surface 61 of the ratchet member 16 by the elastic force provided by the spring 15, whereby the ratchet member 6 When turning against the clock, 'will not be able to rotate due to the stop of the stop block 14, and when the ratchet member rotates 16% clockwise, the stop block 14 will be driven to slide in the direction of the spring cymbal 5, and The return elastic force provided by the spring 15 re-engages to achieve the one-way clutch effect. However, the conventional one-way ratchet wrench must provide a large elastic force by a high-number (K-value) elastic to increase the torque that the stop can withstand, and avoid the tripping of the stop block during operation. However, this method not only improves the difficulty of assembling the ratchet wrench, but after long-term use, the spring will still reduce the elastic force due to the elastic fatigue, so that the stop block cannot effectively mesh with the ratchet member, resulting in energy The 3 M395549 is lowered, and the ratchet member will not slide the slide block to the left because the spring force provided by the spring is large during the clutch operation, causing slippage between the ratchet surfaces. The clutching effect is achieved, but in the long-term, the tooth portion of the ratchet surface such as f is easily damaged, affecting the bite force between the ratchet surfaces, and the rebounding phenomenon occurs when the bombs of the Γ7 square are easy to be separated, that is, After the operating force of the ratchet member in the clockwise direction is stopped, the high-number of bullets will push the ratchet block to slide to the right and drive the ratchet member to rotate counterclockwise by an angle, so that the user must use a larger swing angle. Or for increasing the oscillating number of operations, inviting to plague 'so that there is a real need of improvement. [New content] The present invention provides a ratchet wrench (2), which mainly comprises a main body, a ratchet member, a connecting member and a - limiting unit, wherein the main system is composed of an upper cover and a lower cover stacked on each other.

The large torque does not avoid the effect of returning to the easy to install and cost-saving, and at the same time, it can improve the efficiency of the work. L only mode] Please refer to the -m Λ _ the ratchet wrench main θ kg, is a perspective view of the preferred embodiment of the creation, the pivot 捍 21 drag has a handle 2 〇, and the handle One end of 20 operates through one degree ^. The ratchet unit 30* is connected to the ratchet unit 30*, and the ratchet unit 3* has a plurality of angles and a fourth part of the ratchet unit of the fourth embodiment. The main body 31, a ratchet connector 33 and a limiting unit 34, wherein: the main body of the seven-neck neck 312 defines a head 311, the other end defines a M w, and the main body 31 is composed of a The upper cover 313 and the lower cover 314 are stacked on each other. Further, the φ is extended, and the peripheral edges of the upper cover 313 and the lower cover 314 are adjacent to each other to form a side wall 315. When the upper cover 313 and the lower cover 314 are combined with the M395549, a side is formed between the opposite sides thereof. The upper cover 313 is provided with a first through hole 3131 at the end of the head 311, and the lower cover 314 is provided with a corresponding second through hole 3141, and the main body 31 is at the neck position. The first through hole 317 is inserted through the upper cover 313 and the lower cover 314. The ratchet member 32 is disposed in the chamber 316 of the main body 31 and adjacent to the end of the head portion 311. The two sides of the ratchet member 32 are respectively provided with a locking portion 321 . In this embodiment, The locking portion 321 is a protrusion protruding from the two sides of the ratchet member 32, and the locking portions 321 are respectively pivotally disposed on the first through hole 3131 and the lower cover 314 of the upper cover 313. In the second through hole 3141, the ratchet member 32 can be rotated only around the central axis of the first through hole 3131 and the second through hole 3141. Further, the ring side of the ratchet member 32 is further defined with a first ratchet. The third through hole 331 is formed in the first through hole 317 of the main body 31, and is fixed to the first through hole 317 through the two locking elements 35 to the second through hole.
