[0006] A further setting of the utility model is: the adjusting nut includes a limiting part and an adjusting part coaxially connected and arranged, the limiting part is provided with a rotating hole adapted to the connecting seat, the adjusting part is provided with an adjusting threaded hole adapted to the adjusting threaded tube, the limiting device includes a limiting rod, the limiting part is relatively provided with limiting holes respectively passing through the rotating hole, the above-mentioned limiting rods are arranged in the limiting holes, the limiting part is sleeved on the connecting seat, and the limiting rods all pass through the limiting groove.
[0007] A further setting of the utility model is: the adjusting threaded tube includes a head and a threaded part, and the threaded part is in threaded fit with the adjusting threaded hole.
[0008] The utility model with the above features: When the adjusting nut rotates, due to the cooperation between the limiting rod and the limiting groove, the distance between the adjusting nut and the base remains unchanged during rotation. At the same time, the adjusting screw tube cooperating with the adjusting threaded hole moves forward and backward as the adjusting nut rotates, and the distance between the adjusting nut and the base is avoided from falling off and getting lost.
[0009] A further setting of the utility model is that: an elastic positioning mechanism is provided between the adjusting part and the base.
[0010] A further setting of the utility model is that: the elastic positioning mechanism includes a spring and a ball that abuts against one end of the spring. The base is provided with a spring hole adapted to the spring. The spring is arranged in the spring hole. The end face of the limiting part facing the base is provided with a circumferentially arranged positioning groove, and the positioning groove rotates past the ball along with the limiting part.
[0011] The utility model with the above features: When the adjusting nut rotates, the ball correspondingly enters different positioning grooves to position the adjusting nut. The rotation of the adjusting nut is positioned by the cooperation between the ball and different positioning grooves. At the same time, the impact sound generated when the ball enters the positioning groove serves as a prompt sound to notify the user of the rotation angle of the adjustment and avoid excessive rotation.
[0012] The beneficial effect of the utility model is that: when the adjusting nut rotates, the distance between it and the base remains unchanged, preventing it from completely coming out and avoiding the loss of the whole.
[0013] The following further describes the present utility model in detail with reference to the drawings and embodiments. Description of the Drawings
