13 synchronous axial system；During use, bolt head is inserted in one end that extending part is used for elasticity bolt
Tighten in hole, turning handle 11, make extending part and polygon prism 13 synchronous axial system, so that it may real
The installation or removal of existing bolt.
Extending part is connected with polygon prism 13, and the polygon prism 13 on spanner 12 can be four ribs
Post can also be six prisms etc., and common wrench body 1 mostly is four square head wrenches, i.e. spanner 12
On polygon prism 13 be tetragonal body, one end that extending part is connected with wrench body 1 can have
Four square holes.
The spanner that this utility model detailed description of the invention provides, extending part specifically includes rotor
2 and branch sleeve 3, one end of rotor 2 is connected with polygon prism 13 by branch sleeve 3,
The other end is used for elasticity bolt；Branch sleeve 3 connects polygon prism 13 and rotor 2, then connect
Sleeve 3 two ends are equipped with connecting hole so that polygon prism 13 is inserted into one end of branch sleeve 3
Realization is connected, and rotor 2 is inserted into the other end of branch sleeve 3 and realizes connecting.
Rotor 2 can elasticity bolt, tighten hole due to common bolt head and mostly be interior hexagonal
Shape, so rotor 2 specifically can select interior six sides, interior six sides are simply light and handy, all may be used in two ends
To use, contact area is big during use and between hexagon socket head cap screw, and stress is abundant, is hardly damaged.
Rotor 2 can also select interior four directions wait other instruments, as long as can elasticity bolt, all this
Within the protection domain of utility model.
