A quick-release wrench capable of driving two different bolts includes a head and a handle extending from the head. The head includes first and second jaws. The first jaw includes a plate for contact with a head of a bolt and defines a space. The plate defines a hole in communication with the space. An engagement device includes first and second teeth projecting from a slide and a spring. The first tooth is shorter than the second tooth. The first tooth includes a top and a slope extending from the top. Similarly, the second tooth includes a top and a slope. The top of the first tooth is smaller than the top of the second tooth. The engagement device is received in the space so that the first and second teeth extend through the hole and that the slide is biased by the spring.

1. Field of Invention
The present invention is related to a wrench and more particularly to a quick-release wrench for driving two bolts of different sizes.
2. Related Prior Art
The present invention is described through detailed illustration of embodiments referring to the attached drawings wherein:
FIG. 1 is a perspective view of a wrench capable of driving two bolts of different sizes according to an embodiment of the present invention;
FIG. 2 is an exploded view of the wrench shown in FIG. 1;
Referring to FIGS. 1 and 2, a wrench 10 capable of driving two bolts of different sizes according to the present invention includes a head 14 and a handle 11 extending from the head 14.
Two jaws 12 and 13 extend from the head 14. The jaw 12 includes a plate 121 for contact with a head of a bolt 50 (see FIG. 3) and defines a space 122. The plate 121 defines a hole 123 in communication with the space 122. Similarly, the jaw 13 includes a plate 131 and defines a space 132 and the plate 131 defines a hole 133.
The wrench 10 includes two engagement devices 20 and 30. The engagement device 20 includes teeth 21 and 22 projecting from a slide 23. The tooth 21 is shorter than the tooth 22. The tooth 21 includes a top 24 and a slope 25 extending from the top 24. Similarly, the tooth 22 includes a top 26 and a slope 27. The top 24 is smaller than the top 26. Similarly, the engagement 30 includes teeth 31 and 32 and a slide 33, and the tooth 31 includes a top 34 and a slope 35, and the tooth 32 includes a top 36 and a slope 37.
