[specific embodiment]

Please cooperate and consult shown in Fig. 1 a, Fig. 1 b, Fig. 1 a and Fig. 2-6, the utility model is a kind of interchangeable many specifications spanner, and it comprises:

One wrench body 10, these wrench body 10 at least one ends have two relative pivot ears 11, this pivot ear 11 has a perforation 111, and these 111 convexes of boring a hole set out one first retaining edge 112, and the lateral location of these pivot ear 11 contiguous these perforation 111 is installed certain hyte part 12;

Two buttons 20, the both sides outer peripheral edges of this button 20 are convexly equipped with out one first flange 21 respectively, and this button 20 is to be installed in the perforation 111 of this pivot ear 11, make this button 20 be able to be kept out and unlikely dropping out by this first retaining edge 112;

One pivotal part 30, the outer peripheral edges of this pivotal part 30 are respectively equipped with some operating portions 31, and the side that this pivotal part 30 is positioned at this positioning component 12 is provided with the recessed edge 32 in location that this positioning component 12 of some confessions is located, and the central authorities of this pivotal part 30 have a perforation 33, installing one elastic parts 34 in this perforation 33, and a pushing block 35 is installed at the two ends that are positioned at this elastic parts 34 in this perforation 33 respectively, and this pivotal part 30 is to be installed in this pivot ear 11, this pushing block 35 is able to the elasticity pushing and pressing by this elastic parts 34, makes this pushing block 35 be pushed against this button 20.
