Huai's knowing that the one-way ratchet wrench must be twisted by the elastic force of the high-week (kappa) magazine, and avoid the miscellaneousness of the miscellaneous in operation. However, this method will not only Improve the difficulty of assembling the ratchet wrench, and after long-term use, the spring will still have a low elasticity, so that the support block can not effectively squirt with the miscellaneous wheel parts, resulting in a large drop in the tolerable torque, X, when When the ratcheting device is in the clutching operation, the elastic force provided by the spring is large, and it is not easy to drive the blocking block to slide to the left, causing slippage between the ratcheting surfaces. Although the clutching effect is achieved, the long-term 3 201041696 is down. It is easy to cause damage to the teeth of the ratchet surfaces, affecting the bite force between the ratchet surfaces, == 魏之科_龄___象, scales the ratchet pieces two movements! After the power stops, the high Weizhi The spring will push the ratchet block to the swinging _===, causing the flapper to be larger.

[Ambodiment] A j / H51 7^, a perspective view of a preferred embodiment of the invention, the ratchet stern mainly has a handle 20, and The & pivoting through the pivoting lever 21 _ ' enables the miscellaneous wheel unit 3 〇 to operate in a variety of degrees. =_三_四图, which is an exploded view of the ratchet unit of the present invention, and a 30 31 ^ 32 ^ piece 33 and a limit unit 34, wherein: 〇 the end of the body 31 is defined with a head 3 ιι, the other end is defined as - neck batch, ^ body 31 is composed of: the upper cover 313 and the lower cover 314 are stacked one on another, wherein the periphery of the eclipse 13 and the 5 hai 盍 314 extend close to each other to form When there is a side wall 315, the upper plate (four) is combined with the lower cover 314, a chamber is formed between the opposite sides thereof, and the upper plate 313 is provided with a first perforation at the end of the head 311, and: The running body is provided with a corresponding second through hole 3i4i. The main body 31 is provided with two first through holes 317 extending through the upper cover 313 and the lower cover 314 on the neck scale. The wheel member 32 is placed in the housing of the main body and is adjacent to the head. The two side faces of the X ratchet member 32 are respectively provided with a locking portion milk. In this embodiment, the "stop portion 321" The first perforation 3131 of the upper cover 313 and the second perforation of the lower cover 314 are respectively pivoted from the two sides of the upper cover 313. In the embodiment, the ratchet member 32 can only be rotated about the central axis of the first perforation coffee and the second perforation 3141, and the ring side of the ratchet member is further defined with a first ratchet surface 3211; The connecting member 33 is disposed in the first through hole 317 and the second through hole 331 through the two locking members 35. In the actual remuneration, the element 35 is a rivet, and the connecting piece is fixed in the chamber 316 of the main body 31, and the left side of the connecting member 33 is recessed near the ratchet member 32. There is an open slot 332, and the connecting member 33 is provided with a connecting portion 333 away from the end of the ratchet member 32, and the side of the connecting portion is threaded through The locking hole 334 is disposed in the open slot micro of the connecting member 33, and mainly includes: a supporting block 341 and an elastic member 342, wherein the front end of the supporting block 341 has - The second ratchet surface 34U′ is in contact with the first ratchet surface of the ratchet member 32, and the two sides of the stop block 341 are respectively tightly fitted to the side wall 315 of the main body 31 and the connecting member 33. The inner side of the open groove 332 is formed, and the elastic element is a low-numbered bullet in the embodiment and is disposed between the end of the supporting block and the bottom surface formed by the connecting member and the opening groove 332. For the purpose of this invention, it is believed that the invention can be used in a more in-depth and specific understanding, as follows: (9) The fifth rider is not the moving wire S® of the present invention, and the ratchet member is unable to be clutched by 6 201041696. 'When the ratchet member is in the clockwise direction, the first ratchet face 32U will be the same. The second ratchet surface 34U ^ σ of the stop block 341, and the front portion of the miscellaneous block 341 and the view 315 of the main body 31 will The rear end of the stop block 341 will generate another reaction force due to the action of the lever and the inner side of the open groove 332, so that the support block 341 will be forced toward the ratchet member. The ratchet member 32 can not be rotated. ο shows 'sneak whip _ _, the ratchet member and the = early reading, the situation 'When the slap 32 is called the clock direction, the first ratchet surface _ will be The second ratchet surface 34 of the stop block 341 is in contact with each other, and generates a force toward the open groove 332, so that the support block 341 is slightly oriented toward the open groove = the elastic member 342 is depressed. In conjunction with the ratchet member 32, the ratchet member is slid into the original position by the force of the material, the read, and the thinner, and the ratchet member 32 is re-sprayed, and Since the elastic element is torn into a low-velocity spring, no feedback will occur. Please refer to the seventh figure _, the other part of the system (four) - a partial exploded view of the preferred embodiment, the main structure is the same as the above, and the title is the connection member 33 of the ratchet unit 30. It is made integrally with the handle 2〇, whereby the joint strength can be effectively enhanced, so that the ratchet unit 3 can be applied to a large 'workland'. Please refer to the eighth embodiment, which is a partially exploded view of another preferred embodiment of the present invention. The main structure is the same as the preferred embodiment described above, and the ratchet single microfiber is at both ends. 31I, ^=u 7 201041696 More extensions - _ section (10), sold in the county, and each of the ratchet parts are cut, q head. The inner diameter of the I5 311 wheel member 32 can be: no interesting unit, the workpieces of different sizes can be spurred, and the miscellaneous wheel can be used to facilitate the operation of the user. Effect = The characteristics of this turn and its achievable functions are stated below. The wrench structure (2) can reach -1 force through the (four) design and the above structure, and between the block and the connector The resulting miscellaneous wheel plate H is to make the low Wei installation more __. h is not only convenient, but also has its excellent progress and practicality in similar products. At the same time, the technical information about such structures at home and abroad, the same structure is not found in the literature. 'The invention has the invention patent requirements, and loves to apply according to law. The above is only one of the preferred embodiments of the present invention, and it is intended that the equivalent of the application of the present invention and the patent application are included in the scope of the present invention. 201041696 f BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a cross-sectional view of a head of a conventional ratchet wrench.
