Described bolt head is made into cuboid, and the outside, cuboid right side of described bolt head has made the first chamfering, and the inner side, cuboid left side of described bolt head has made the second chamfering.Central axis with bolt head cuboid between the circular arc end face that the first described chamfering and the second chamfering form is symmetrical.
On the cuboid its right end face medial angle of described bolt head, made successively the first plush copper, the second plush copper and the 3rd plush copper, the groove that cuts off of circular arc is carved with in the connection place of the first described plush copper, the second plush copper and the 3rd plush copper.The inner surface of the first described plush copper, the second plush copper and the 3rd plush copper is made into circular arc, and the inner arc face of the first described plush copper connects with the first chamfering is smooth.
On the cuboid left end face lateral angle of described bolt head, made successively the 4th plush copper, the 5th plush copper and the 6th plush copper, the groove that cuts off of circular arc is carved with in the connection place of the 4th described plush copper, the 5th plush copper and the 6th plush copper.The inner surface of the 4th described plush copper, the 5th plush copper and the 6th plush copper is made into circular arc, and the inner arc face of the 6th described plush copper connects with the second chamfering is smooth.
Basic principle of the present utility model: use after the utility model, the cuboid of bolt head is rotated to parallel with bolt slot, the cuboid of bolt head is filled in to bolt slot, clockwise rotate shank of bolt, now the plush copper on bolt head both sides is blocked bolt slot, prevents whole bolt transfer.
The beneficial effects of the utility model are:
(1) bolt head is made into cuboid, can be at bolt slot optional position Fast Installation bolt.
(2) bolt head is provided with multistage spacing plush copper, can be according to the width adjusting in bolt slot.
(3) make and install simply, being easy to production operation.
