It should be noted that even if the two toothed surfaces are in meshing, when the adjusting nut 104 rotates due to vibration, the two toothed surfaces will be in meshing in time, so as to play a fixing role.
[0031] The end of the handle 106 and the adjusting nut 104 is hingedly connected and is provided with a sliding groove 114, when the handle 106 is rotated, the position of the sliding groove 114 will also change, the top of the pressing rod 112 is located in the sliding groove 114, the top of the pressing rod 112 is rotatably connected with a roller, when the handle 106 is rotated to be horizontal, the sliding groove 114 is located directly above the pressing rod 112, at this time, the pressing rod 112 will move upwards, so as to enter the sliding groove 114 and drive the fixing block 113 at the bottom to be separated from the toothed ring 108.
[0032] When the toothed surfaces on the toothed ring 108 and the fixing block 113 are not aligned in use, the pressing rod 112 is located above, which will cause the handle 106 to be unable to be horizontal. The following provides a structure that can adapt to this situation: specifically, referring to Figure 2 , the inside of the fixing block 113 is provided with a second cavity 115, the bottom of the pressing rod 112 extends into the second cavity 115, when the two teeth are not aligned, the pressing rod 112 will move downwards in the second cavity 115 until the two teeth are aligned, the pressing rod 112 and the second cavity 115 are connected through the spring 111.
