[Prior Art] rn 7Γ: The open-end wrench in the telescopically positionable position is changed by the extension of the length to achieve the effect of the force: the opening plate ... contains - (four) f. Degree—= The expansion and contraction inside the outer tube 10 is recognized by the hai cup 11, the operation set outside the outer tube 1G, the clothes 12, the balls 13, the string of pins, the buckles 15, and the elastic element 16 and a resisting member 17 that abuts against the inner side wall surface of the outer tube 10. The foreign official ίο has a perforation 101 to provide the ball 13 setting. The telescopic rod 11 has a plurality of positioning holes U1 and a groove ι2. The positioning holes 111 are provided to engage the balls 13 to fix the telescopic length. The groove 112 is engaged with the string 14 when the telescopic rod n is When the end is pulled, the party will reach the top of the string 14 without coming out. When the operating ring 12 is pulled toward the buckle 15, the elastic member 16 is in a compressed state, and the ball 13 can be pulled out of the positioning hole U1 to pull the telescopic rod 1 out. Although the telescopic rod 11 can be expanded and contracted relative to the outer tube 10 to achieve the effect of adjusting the length of the arm, there are still the following disadvantages: 1) Since the open end wrench 1 〇〇 only uses one ball 13, the snap positioning The lack of force is not even, so the user often feels the feeling of shaking when pulling the outer tube 10. 5.2. Since the positioning hole lu of the open-end wrench 100 is a concave hole located at a local position, the gap between the groove 112 and the string 14 has a tolerance, so the telescopic rod u tends to be pulled out. Turning to the left and right offset, the ball 13 is not easily engaged into the A-position hole 111, so the length of the pull-out can easily exceed the position of the positioning hole Ui that the user wants to fix, which causes the operation to be quite unsatisfactory, often It takes time to repeatedly adjust the operating ring 12 and the telescopic rod 11 to reach the desired length. 3. The outer wrench (7) and the open-end wrench 100 are engaged in a telescopic operation. The singular operation % 12 must be applied in the opposite direction so that the ball 13 can be disengaged from the positioning hole m, so that the telescopic rod u can adjust the extension length in the direction desired by the user, and since the user must use one Only one hand adjusts the telescopic rod 11, and the other hand also needs to make two opposite directions of force to pull the outer tube (7) and push the "Xuan operation % 12", so the operation is quite inconvenient for the user. It is also not easy to handle. The composition of the open σ wrench touch is not intuitive and user-friendly.
