360-degree rotation adjusting device and police law enforcement equipment

The utility model discloses a 360-degree rotation adjusting device and police law enforcement equipment comprising the 360-degree rotation adjusting device. The 360-degree rotation adjusting device comprises a rotatable main body, and a clamping seat which is embedded into the rotatable main body, wherein the rotatable main body is a cylinder of which the two ends are open; the inner wall of the rotatable main body is provided with a plurality of clamping grooves along the axial direction of the rotatable main body; the clamping seat is a cylinder of which one end is open; buckles are arranged on two opposite sides of the clamping seat respectively; the two buckles are fixedly connected through a first spring; the two buckles are embedded into the corresponding clamping grooves for positioning the rotatable main body. The clamping grooves and the buckles are matched with each other, thus the buckles are pushed inwards when the rotatable main body rotates, and the two buckles are ejected back through the first spring when the rotatable main body stops rotating, so that the two buckles are embedded into corresponding clamping grooves, and the positioning of the rotatable main body is realized. By adopting the 360-degree rotation adjusting device, optional 360-degree rotation of the rotatable main body can be realized smoothly, and the rotatable main body can be positioned at a target angle conveniently and rapidly.
