The side wall of the neck is provided with the positioning hole one connected with bolt rostral wall, and the side wall of the screw rod is provided with perpendicular to screw rod
The positioning hole two of axis, the connection-peg is provided with through hole, screw rod and positioning hole one, positioning hole two and through hole after bolt head assembling
Center line be located along the same line, through there is alignment pin in the positioning hole one, positioning hole two and through hole.
It is preferred that, the groove is hexangle type or cross.
It is preferred that, the positioning hole one and positioning hole two are square or circle.
It is preferred that, the connection-peg and slot are square or cross.
The invention discloses a kind of bolt, it is detachably connected between bolt head and screw rod, so when the groove on bolt head
After being damaged, replaceable complete bolt head realizes tightening or unscrew to screw rod, in the present invention, the lower surface of bolt head
The neck being engaged with screw rod outer wall is set, and when mounted, the outer wall of screw rod is contacted with the side wall of neck, the connection-peg in neck
Be engaged between the slot of screw rod upper surface, by neck, connection-peg and slot can more stablize realize bolt head with
Circumferentially positioned after screw rod installation, the positioning hole one on bolt head, the positioning hole two on the wall of screw rod side and alignment pin can be realized
Bolt head and screw rod install after axially position, by being positioned to circumferential and axial, prevent the mechanical parts that connect by
Violent vibration makes bolt head be come off from screw rod during rocking, it is ensured that the stability installed therebetween.
Positioning stablity between bolt head and screw rod of the present invention, it is not easy to the phenomenon that bolt head comes off from screw rod occur, leads to
Dismountable mounting means is crossed, is easy to change the bolt head of damage, so as to not interfere with the assembly and disassembly of mechanical parts.
