By adopting technique scheme, chek bolt is fixedly connected with two mechanical parts with through hole, tighten after chek bolt, rotary gland makes it move to groove diapire, order about anti-release member moves and exposes outside through hole in groove, elastic component is compressed simultaneously, anti-release member is connected mechanical parts mounting surface and stings mutually tightly with being fixed, reach anti-loosing effect, in the time that needs are dismantled chek bolt, first rotary gland moves it outside groove, anti-release member can be under the resilient force of elastic component in indentation through hole, remove anti-release member tight to stinging of mechanical parts mounting surface, being convenient to bolt back-outs, be convenient to dismounting.
The utility model is further set to: it is cone shape that described anti-release member is exposed the outer one end of through hole.
By adopting technique scheme, be convenient to anti-release member and sting the connection mechanical parts mounting surface that is tightly fixed, improve anti-loosing effect.
The utility model is further set to: the spherical that the inconsistent end face of described anti-release member and gland is outwardly convex.
By adopting technique scheme, reduce anti-release member and gland area of contact, rotary gland drives anti-release member to move down, and can reduce, to anti-release member lateral force, to be convenient to anti-release member and to move down.
The utility model is further set to: the relative anti-release member of described gland other end is provided with straight groove, and two madial wall intermediate portions of described straight groove are equipped with the rectangle groove caving inward, and the diapire intermediate portion of described straight groove is provided with the square groove caving inward.
By adopting technique scheme, rotary gland, can use a word spanner, cross like spanner and one of them spanner of square spanner tighten or unclamp, and makes bolt using scope wider.
The utility model is further set to: described deep gouge is four and evenly circle distribution is on groove diapire, and on described deep gouge, central axis and through hole central axis are same straight line.
By adopting technique scheme, it is more reasonable that described deep gouge distributes, and is convenient to manufacture, and on described deep gouge, central axis and through hole central axis are same straight line simultaneously, are convenient to process deep gouge and through hole, reduce manufacture cost.
