According to the bolt structure, a bolt head comprises a step-shaped clamping block and a top block, and an elastic piece is installed on the side, back on to a screw rod, of the top block; during installation, the screw head penetrates through a through hole of a part and then is rotated by a certain angle, the elastic piece ejects the screw head and the screw rod outwards, the clamping block clamps the inner wall of the through hole, the ejection block abuts against the side face of the part, and then the nut is screwed in. The bolt is simple in structure and convenient to operate, the bolt and the nut can be operated from the same side, hindrance caused by the shape structure, the size or the installation environment of parts is avoided, connection and fixation between the parts are achieved, and the connection strength between the parts can be improved. 一种螺栓结构，螺头包括阶梯状的卡块和顶块，顶块背向螺杆的一侧装有弹性件；安装时将螺头穿过零部件通孔，然后转动一定的角度，弹性件将螺头和螺杆向外顶，使卡块卡紧通孔内壁、顶块抵紧零部件侧面，再旋入螺母即可。该种螺栓的结构简单、操作方便，可从同一侧操作螺栓和螺母，避免因零部件形状结构、体积或安装环境带来的阻碍，实
