Referring to fig. 3 and 4, fig. 3 shows a left side view of an embodiment of the invention, and fig. 4 shows a cross-sectional view of fig. 3 along section a-a.
In some embodiments, the ratchet 440 includes ratchet teeth 450 and curved surfaces 470, the ratchet teeth 450 and the curved surfaces 470 are distributed along the inner wall of the ratchet 440, the ratchet teeth 450 are shaped and sized to fit the pawl 230, the number of the ratchet teeth 450 is set according to the maximum rotation angle, the maximum rotation angle can be set according to the user's requirement, the arrangement and number of the ratchet teeth 450 are related to the maximum rotation angle and the angle of each rotation, and the ratchet teeth 450 are used to engage with the pawl 230, so that the rotating assembly 100 can rotate and stay at a certain angle, thereby achieving the function of adjusting the rotation angle.
In some embodiments, the first elastic member 430 is a compression spring, one end of the compression spring abuts against the shaft 110, and the other end of the compression spring abuts against the pawl 230, and the compression spring gives the pawl 230 a force close to the ratchet 450, i.e., the first elastic member 430 is used for providing an axial elastic force to the pawl 230. When the ratchet 440 performs a forward rotation, the first elastic member 430 applies an elastic force to the pawl 230 so that the pawl 230 can rotate from one ratchet tooth 450 to another ratchet tooth 450, and the pawl 230 and the ratchet teeth 450 can always maintain an engaged state without other external force, thereby supporting the rotating assembly 100 to adjust various angles.
In some embodiments, the shaft body 110 is provided with a receiving groove 530, and a hole is formed in the receiving groove 530 and is used for receiving the first elastic member 430, so as to stabilize the first elastic member 430 and prevent the first elastic member 430 from shaking greatly.
In some embodiments, a return mechanism 240 is also included, the return mechanism 240 for moving the pawl 230 away from the ratchet teeth 450. Ratchet 440 can only rotate in a forward direction due to the blocking of pawl 230, and reverse rotation is often required when rotating assembly 100 is in use, and when reverse rotation is required, pawl 230 can be disengaged from ratchet teeth 450 by return mechanism 240 to allow reverse rotation of ratchet 440 without being blocked by pawl 230.
In some embodiments, a second hole is formed at one end of the returning mechanism 240, the connecting column 510 can pass through the second hole to fix one end of the returning mechanism 240, at this time, the connecting column 510 can simultaneously pass through the first hole and the second hole, and the pawl 230 and the returning mechanism 240 can both rotate around the connecting column 510. When the rotating assembly 100 needs to rotate in the forward direction, the return mechanism 240 can disengage from the pawl 230, and when the rotating assembly 100 needs to rotate in the reverse direction, the return mechanism 240 also rotates to contact with the pawl 230 and pushes the pawl 230 away from the ratchet 450, so that the ratchet 440 can rotate freely, and the function of reverse rotation is realized.
In some embodiments, the pawl 230 is provided with a first engaging groove 420, a retaining surface 460 is provided between the ratchet 450 and the arc surface 470, the return mechanism 240 is rotatably connected to the shaft 110, the return mechanism 240 is located in the ratchet 440, the retaining surface 460 can clamp the return mechanism 240 into the first engaging groove 420, during the rotation of the ratchet 440, when the retaining surface 460 rotates to the pawl 230, the retaining surface 460 can slowly clamp the return mechanism 240 into the first engaging groove 420, so that the pawl 230, the return mechanism 240 and the first elastic member 430 are in a stress balance state and are away from the ratchet 450, at this time, the first elastic member 430 applies a first axial force to the pawl 230, the return mechanism 240 applies a second axial force to the pawl 230, the first axial force is opposite to the second axial force, and the first axial force and the second axial force are mutually offset, so that the pawl 230, the return mechanism 240 and the first elastic member 430 are in a relatively fixed state, since the abutment 460 pushes the return mechanism 240 and the pawl 230 away from the ratchet teeth 450, the pawl 230 cannot engage with the ratchet teeth 450, and the ratchet 440 can rotate in both forward and reverse directions.
In some embodiments, after the holding surface 460 rotates past the pawl 230, the holding surface 460 does not completely clamp the return mechanism 240 to the first slot 420, and at this time, the arc surface 470 continuously clamps the return mechanism 240 until the return mechanism 240 does not touch the ratchet 440 after the return mechanism 240 clamps the first slot 420.
In some embodiments, the receiving groove 530 may also be used to place the detent 230, and the detent 230 is pushed into the receiving groove 530 after the return mechanism 240 is snapped into the first card slot 420.

Through the blocking of the first baffle plate 410, the rotating assembly 100 can be adjusted in angle through the mutual matching of the return mechanism 240 and the first baffle plate 410 in the rotating process, and the rotating assembly 100 can be restored to the original state when the rotating assembly 100 is not needed to be used.
In some embodiments, the shaft body 110 is provided with a second baffle 520, the second baffle 520 is used to adjust a rotation amplitude of the return mechanism 240, when the return mechanism 240 rotates away from the first slot 420, if the rotation amplitude is too large, the return mechanism 240 cannot contact the abutting surface 460, and the abutting surface 460 is blocked between the return mechanism 240 and the pawl 230, so that a return function cannot be realized, and therefore, the rotation amplitude of the return mechanism 240 cannot exceed a plane where the abutting surface 460 is located, so that the return mechanism 240 can contact the abutting surface 460, and a return function is realized.
In some embodiments, the shaft body 110 is provided with a second elastic element 250, the second elastic element 250 may be a spring, a torsion spring or other elastic elements, the second elastic element 250 is sleeved on the shaft body 110, the second elastic element 250 is disposed between the shaft body 110 and the housing 130, and one end of the second elastic element 250 abuts against the rotating element 120 to stabilize the rotating element 120, so as to prevent the rotating element 120 from shaking too much to affect the rotating effect.
