M259673

[New type of technology creation belongs to the creation of the elastic parts of the creation order and the retraction of the ratchet wrench. [Previous technology] According to its main wheel, it is also wrong to set up the Republic of China 414119. Use a ratchet ratchet or use a groove. The inner wall, but the wall, because of the easy installation of spring and spine blocks, is also used in the same system, but this type of plan to change the square action, due to the Lee Bulletin public notice, the announcement of the face-changing hands-on structure and these single spring cross-shaped drills If such a device is to be used, it must be swayed at the cost of the spring. The above-mentioned fields are two types of one-way ratchet wrench manufacturing technology, through 5 between the one-way ratchet block and the bearing plate, and let the single The special design of the spine block with the same axis as the elasticity makes the unidirectional and assembly easier, and the operation is smoother. The hand is a kind of hand tool that can be locked and idled, and the two-way ratchet wrench is more structured than a reversing lever, and its movement is easy to report the development of the so-called one-way ratchet wrench. No. 281946, PN 379624, 469909, and PN 577369 to achieve the purpose of two-way operation, and 'to reduce the difficulty and cost of manufacturing; ratchet wrench, regardless of the use of impeachment to support, etc., must be in A one-way one spring receiving hole is accommodated, so that the spring can be set. Since the spring receiving hole is extremely difficult to set up, it is often not necessary to first align the spring receiving hole, and it is correct. In other words, its manufacturing and manufacturing are also relatively high. The spring and single-turn structure of the conventional one-way ratchet wrench are both bidirectional and require wear and tear, such as Zhonghua No., Bulletin No., etc. The arc insertion and positioning of the longitudinal telescopic ratchet block are good products in the arc insert slot, and when the one-way installation is not considered, the relation of the ratchet block is not allowed.
