Coordinate, driver flutes are offered on the top of mounting cap, be provided with the bottom of nut a plurality of along the radially-arranged anti-skidding of nut
Convex tendon, the cutter head of screwdriver can be used to be stuck in driver flutes to be rotatablely installed cap so that pacifying when the bolt is being used
Threaded portion in behaveing affectedly coordinates with the second screw flight section screw thread so that mounting cap is screwed into the on the second screw rod, works as installation
Cap is rotated further mounting cap after being tightened, and the first screw rod can be driven to rotate for mounting cap so that the first screw rod pierces interior of articles,
, it is necessary to rotate backward mounting cap when the bolt is being dismantled, now mounting cap can release, and mounting cap will not give the first spiral shell
The counter-rotational power of bar so that the bolt is not easy to be removable, due to being provided with anti-skidding convex tendon in the bottom of nut, when bolt is tight
Gu when anti-skidding convex tendon in insert body and then can prevent the bolt from producing loosening due to vibrations, compared with prior art, can
Effectively prevent bolt from arbitrarily being dismantled by other people, effectively prevent bolt looseness, improve the safety and reliability that bolt uses, tie
Structure is simple, easy to use, easy to utilize.
Feature and advantage of the present utility model will be described in detail by embodiment combination accompanying drawing.
【Brief description of the drawings】
Fig. 1 is a kind of structural representation of anti-theft bolt of the utility model.
Fig. 2 is a kind of structural representation of the mounting cap of anti-theft bolt of the utility model.
In figure：The anti-skidding convex tendon of 1- nuts, 11-, the screw rods of 2- first, 3- mounting caps, 4- installation cavitys, 5- threaded portions, 6- are smooth
