The rotating mechanism includes a fixed block 103, a vertical rod 104, a limiting rod 105, a disk 106, a rotating head 107, a rotating disk 108 and a small spring 109. The fixed block 103 has a groove 110, and the fixed block 103 also has an annular groove 111 and a limiting groove 112. The outer wall of the bolt body 101 has a thread line 113.
[0022] According to this specific embodiment, the limiting rod 105 is adapted to the limiting groove 112, and then the vertical rod 104 is pulled to make the limiting rod 105 enter the limiting groove 112, and then the vertical rod 104 is rotated, and then the limiting rod 105 is rotated, thereby driving the fixing block 103 and the bolt body 101 to rotate, so that the bolt body 101 enters the screw hole or rotates out of the screw hole, thereby the bolt body can be tightened or removed without the assistance of a wrench, and the operation is simple and fast. The setting of the disc 106 and the annular groove 111 can prevent the vertical rod 104 from being pulled outward due to excessive pulling distance, causing the vertical rod 104 to disengage from the groove 110. The setting of the rotating head 107 is convenient for the staff to perform the rotation operation and avoids direct rotation In the case where the vertical rod 104 is more laborious, the small spring 109 is provided to limit the disc 106 to prevent the limiting rod 105 from entering the limiting groove 112 when the vertical rod 104 is not rotated, and the rotating disk 108 is provided to enable the disc 106 and the spring to rotate together, so that the limiting rod 105 is rotated to other positions of the annular groove 111 and is not in the same position as the limiting groove 112. When the bolt body 101 needs to be disassembled or installed, the vertical rod 104 is rotated again to bring the limiting rod 105 into the limiting groove 112 for use, and the thread line 113 is adapted to the screw hole, so that the bolt body 101 enters the screw hole, and the gasket 102 can provide additional friction to prevent the bolt body 101 from loosening.
[0023] In which, the fixing block 103 has a groove 110, and the fixing block 103 also has an annular groove 111 and a limiting groove 112. The annular groove 111 is connected to the groove 110, and the limiting groove 112 is located above the annular groove 111 and is connected to the annular groove 111 and the groove 110.
