The abutting surface 112 of the body 10 is abutted against one side of the screwing member 50. The first locking portion 21 and the second locking portion 22 of the locking block 20 are adjacent to the screwing member 50. At the two sides, the screw member 50 has three side faces which are abutted against each other and have a more rotational torque. The open-end wrench structure can have a better rotational torque state.

3. The elastic member 30 is received in the elastic groove 24 of the clamping block 20, and one end is abutted by the pivot rod 46. When the screwing member 50 is rotated, the moving range of the elastic member 30 is received by the elastic groove 24. Limit, not to disengage.

4. The card block 20 is provided with a curved groove 25 extending therethrough. The arc groove 25 is a guiding path for the displacement and return of the pivot rod 46. The two cover plates 40 are respectively coupled to the two bodies 10 At the upper and lower sides, the two cover plates 40 can cover the curved groove 25, and the elastic member 30 is hidden inside, so that the appearance is better.

5. The body 10 is two-shaped, so that each body 10 has a small thickness. If the body 10 is formed by a stamping machine forming method, the punching force can be small, and the body 10 has a smaller size. Stamping stress.

Therefore, the open-end wrench structure of this creation has profound industrial value, novelty and progress, and can meet the application requirements of the new patent, and apply in accordance with the law.
