Detailed Description

For the purpose of illustrating the spirit and purposes of the present invention, the present invention will be further described with reference to the accompanying drawings and specific embodiments.

A first embodiment, as shown in fig. 1 to 5, an angle adjuster includes an upper rotation arm 10, a lower rotation arm 20, a movable stopper 30, a rotation shaft 50, a return spring 60, and a rotation disc 40; go up pivot 10 and pivot 20 down and rotate and connect, pivot 20 one end down is equipped with first articulated portion 21, the upper surface of first articulated portion 21 is equipped with first holding tank 22 to the indent, the internal perisporium of first holding tank 22 is equipped with arc draw-in groove 23, arc draw-in groove 23 is semi-circular structure, arc draw-in groove 23 equipartition is at the internal perisporium of first holding tank 22, adjacent arc draw-in groove 23 connects gradually, first articulated portion 21 is circular structure, the thickness of first articulated portion 21 is less than pivot 20 thickness down. The outer wall of rolling disc 40 is equipped with the elastic tooth 41 with the mutual chucking of arc draw-in groove 23, and rolling disc 40 runs through to have first logical groove 42 and first logical groove 42 to be close to elastic tooth 41, and elastic tooth 41 has certain elasticity, and elastic tooth 41 is semi-circular structure, and when external force butt elastic tooth 41, elastic tooth 41 takes place elastic deformation to first logical groove 42. The movable plug 30 comprises a chassis 31, a boss 32 which is arranged on the upper surface of the chassis 31 and matched with the first through groove 42 and a pin 33 which is arranged on the upper surface of the boss 32 and inserted into the first through groove 42, a gap exists between the pin 33 and the inner wall of the first through groove 42, the size of the boss 32 is slightly smaller than that of the first through groove 42, when the boss 32 is positioned in the first through groove 42, the outer wall of the boss 32 is in contact with the inner wall of the first through groove 42, at the moment, when external force abuts against the elastic teeth 41, the elastic teeth 41 are deformed less. One end of the return spring 60 contacts with the bottom of the first receiving groove 22, and the other end contacts with the lower surface of the chassis 31, and the return spring 60 pushes the boss 32 so that the boss 32 is located in the first through groove 42; one end of the upper rotating arm 10 is provided with a second hinge part 11, the second hinge part 11 is fixedly connected with the rotating disc 40, and the rotating shaft 50 sequentially passes through the second hinge part 11, the rotating disc 40, the movable plug 30 and the return spring 60 and then is fixedly connected with the bottom of the first accommodating groove 22; under the action of the return spring 60, the boss 32 is clamped into the first through groove 42, the outer wall of the boss 32 is in contact with the inner wall of the first through groove 42, the upper rotation arm 10 is stationary relative to the lower rotation arm 20, when the boss 32 is separated from the first through groove 42 under the action of external force, the upper rotation arm 10 is rotated, the elastic tooth 41 can be clamped into and separated from the arc-shaped clamping groove 23, and at this time, the upper rotation arm 10 can rotate relative to the lower rotation arm 20.
