"Bu: operation: ring 12, - ball 13, a string 14, a buckle 15, an elastic element ", and a resisting member 17 that abuts against the inner side wall surface of the outer tube 10. The outer tube ίο has a perforation The ball 13 is provided. The telescopic rod 11 has a plurality of positioning holes U1 and a groove 112. The positioning holes 111 are provided for engaging the ball 13 to fix the telescopic length. The groove 112 is matched with the string 14 When the telescopic rod u is pulled to the end, it will be abutted by the string 14 without being pulled out. When the operating ring 12 is pulled toward the buckle 15, the elastic member 16 will be in a compressed state, and the ball is in a state of compression. 13 can pull out the telescopic rod 11 out of the state of the positioning hole. Although the 'distant telescopic rod 11 can be expanded and contracted relative to the outer tube 1 to achieve the effect of the arm length adjustment, there are still the following Disadvantages: 1_ Since the open-end wrench 100 only uses one ball 13, the force of the snap-in positioning is insufficient and not even, so the user often feels the feeling of shaking when the outer tube 10 is pulled. 2. 200914209 The positioning hole ill of the open-end wrench 100 is located The hole at the position of the hole has a gap between the groove 112 and the string 14 so that the telescopic rod 11 tends to turn left and right when pulled out, so that the ball 13 is not easily engaged to the positioning. In the hole 111, the length of the pullout easily exceeds the position of the positioning hole 111 that the user wants to fix, which causes the operation to be quite unsatisfactory. The crane often takes time to repeatedly adjust the operating ring 12 and the telescopic rod 11 to reach. The required length is 3. When the open-end wrench 100 is performing the telescopic operation, the outer tube 10 and the operating ring 12 must be biased in opposite directions, so that the ball 13 can be disengaged from the positioning hole lu, so that the telescopic rod u can adjust the extension length in the direction required by the user, and since the user has to adjust the telescopic rod 11 with only one hand, the other hand also has two opposite directions of force to pull the outer tube 10 And the operation of the operation ring 12 is not convenient for the user, and the composition of the open-end wrench 1〇〇 lacks an intuitive and user-friendly operation. [Invention] The purpose of the invention is to provide a ratchet wrench with a shank telescopic positioning device that can be quickly and firmly engaged to a desired length when performing the telescopic operation 2.
