The right half part of the bolt mandrel is of a slope structure.
The number of the steel ball limiting grooves is two.
The bayonet lock sleeve is integrally formed by a steel machine.
The core rod guide sleeve is a PE core rod guide sleeve.
The gasket is a nylon gasket.
The utility model discloses a theory of operation: the bayonet lock sleeve pipe is connected through cooperating with bolt dabber, plug direction, nylon gasket, spring, snap ring, steel ball, and through pressing the bolt dabber, compression spring, the steel ball of steel ball spacing inslot portion contracts through the slope of bolt dabber, makes quick self-tightening locating pin pack downthehole, then loosens the bolt dabber, and the spring replies, makes bolt dabber auto-eject, and the steel ball is automatic ejecting, and the card is in the hole steel ball spacing groove to reach quick location and self-tightening effect.
After the technical scheme is adopted, the utility model discloses beneficial effect does: it can fix a position fast and from tighting, and the application is more nimble convenient than traditional locating pin.
