Detailed Description

The technical solution of the present invention will be more clearly and completely explained by the description of the preferred embodiments of the present invention with reference to the accompanying drawings.

As shown in fig. 1, the human face attendance machine support in the preferred embodiment of the utility model comprises a gooseneck 1, a connecting block 2, a rotating sleeve 3 and a mounting rack 4.

The one end of gooseneck 1 is fixed with clip 5, and connecting block 2 is fixed at the other end of gooseneck 1, and connecting block 2 is cylindrical, changes cover 3 and rotates to be connected on connecting block 2, changes cover 3 and is cylindrical equally, changes the axis of cover 3 and the coincidence of the axis of connecting block 2, and mounting bracket 4 rotates to be connected on changeing cover 3, and mounting bracket 4's pivot is along changeing the radial of cover 3, and the attendance machine is installed on mounting bracket 4.

The attendance machine can rotate through gooseneck 1, commentaries on classics cover 3 or mounting bracket 4 rotates and comes angle of adjustment, and clip 5 can press from both sides in positions such as table limit, makes the attendance machine no longer can only install on the wall.

As shown in fig. 2, a ratchet structure is arranged between the rotating sleeve 3 and the connecting block 2, and the ratchet structure comprises a bayonet 6, a ratchet groove 7, a sliding groove 8 and a spring 9.

The length direction of spout 8 is unanimous with the radial direction of commentaries on classics cover 3, bayonet lock 6 sliding connection in spout 8, and spring 9 is in spout 8, and spring 9's both ends are contradicted with bayonet lock 6 and the bottom side surface of spout 8 respectively, and ratchet groove 7 is on connecting block 2, and ratchet groove 7 is provided with a plurality ofly along the axis of connecting block 2, preferably 4. In a normal state, one end of the bayonet 6, which is opposite to the spring 9, is abutted against the ratchet groove 7, when the rotating sleeve 3 rotates relative to the connecting block 2, the bayonet 6 can compress the spring 9 until the bayonet 6 is completely retracted into the sliding groove 8 and does not protrude out of the outer surface of the rotating sleeve 3, and finally when the bayonet 6 rotates to the other ratchet groove 7, the bayonet 6 is driven by the spring 9 to be clamped at the position of the other ratchet groove 7.

The spring 9 with the ratchet structure provides resistance for the rotation of the rotating sleeve 3 relative to the connecting block 2, and the resistance of the deformation of the spring 9 is overcome when the rotating sleeve 3 rotates every time, so that the rotating sleeve 3 cannot rotate relative to the connecting block 2 at will and has certain stability.

A linkage seat 17 is fixed on the peripheral wall of the rotating sleeve 3, a linkage rod 18 is fixed on the mounting rack 4, and the linkage rod 18 is relatively rotatably arranged on the linkage seat 17, so that the mounting rack 4 can rotate relative to the rotating sleeve 3.
