Specific implementation mode
In the following, in conjunction with attached drawing and specific implementation mode, the utility model is described further, it should be noted that
Under the premise of not colliding, it can be formed in any combination between various embodiments described below or between each technical characteristic new
Embodiment.
A kind of spanner as shown in Figs. 1-3, including it is provided with the wrench body 30 of open slot；The spanner further includes slidably
Ground is mounted on sliding block 10, the first elastic element 20 in wrench body 30；Arc groove 11 is provided on the sliding block 10, it is described to pull
Round pin 40 is fixed on hand ontology 30, the round pin 40 is inserted into arc groove 11, and arc groove 11 is slidably matched with round pin 40；
First elastic element 20 is mounted in arc groove 11, and is supported between round pin 40 and sliding block 10；The sliding block 10 stretches into
In open slot, and threaded fittings nestion mouth is cooperatively formed with the cell wall of open slot；The cell wall shape of wherein one end of the open slot
As for threaded fittings against against wall surface 35, the sliding block 10 far from should be formed as against one end of wall surface 35 for to
It is opposite by wall surface 35 and for threaded fittings against abutment end 12.
When in use, can by threaded fittings in the threaded fittings nestion mouth, and make the threaded fittings be clamped in against
Between wall surface 35 and abutment end 12, at this point, the first elastic element 20 is in compressive state and then rotates forward spanner, to drive spiral shell
Line accessory rotates, and in threaded fittings rotation process, the first gradually elongation of elastic element 20, if at this point, spanner encounters the external world
When component, spanner can be rotated backward, and sliding block 10 is with the generation of spanner opposite thread accessory in spanner counter rotation
Counter motion, and first elastic element 20 that gradually reduces, and after spanner rotates backward in place, continue to rotate forward spanner, with
