Example one

Referring to fig. 1-5, a headrest bracket assembly with an improved structure comprises a base plate 1, a buffering mechanism 2 is fixedly connected to one side of the base plate 1, a fixing mechanism 3 is fixedly connected to the other end of the buffering mechanism 2, a sleeve 4 is arranged in the fixing mechanism 3, a sliding groove 5 is formed in the inner wall of the sleeve 4 at the rear side, a plurality of limiting holes 6 are formed in one side of the outer portion of the sleeve 4, a magic tape 7 is fixedly bonded to the side, a fixing arm 8 is movably connected to the inner portion of the sleeve 4, a limiting chuck 9 is fixedly connected to one side of the fixing arm 8, the size of the limiting chuck 9 is matched with that of the limiting holes 6, a sliding rail 10 is fixedly connected to the other side of the fixing arm 8, and the size of the sliding rail 10 is matched with that of the sliding groove 5;

further, a fixing sleeve 22 is arranged on the other side of the substrate 1, two ends of the fixing sleeve 22 are of rectangular block structures, two sides of the fixing sleeve 22 are both provided with unthreaded holes 21, and fixing bolts 23 are connected to the inner threads of the unthreaded holes 21;

furthermore, a plurality of mounting holes 20 are formed in the substrate 1 at the same side as the fixing sleeve 22, the mounting holes 20 correspond to the unthreaded holes 21 in the fixing sleeve 22, and the fixing bolts 23 penetrate through the unthreaded holes 21 and are in threaded connection with the mounting holes 20;

when using the device, firstly fixing the device;

sleeving a fixing sleeve 22 on one side of a substrate 1 on a framework in an automobile seat, then firmly fixing the fixing sleeve 22 on the substrate 1 through a fixing bolt 23, and further fixing the whole device on the automobile seat through the fixing effect of the fixing sleeve 22;

when the installation headrest, place the headrest in one side of sleeve 4 in fixed establishment 3, the user need set up the device of bonding usefulness with the position of headrest with sleeve 4 contact to can tightly bond together with magic subsides 7, and when the headrest to equidimension not, the user can stretch fixed arm 8 in fixed establishment 3 to the outside, makes 9 cards of spacing dop inside spacing hole 6 near the outside, and then improves the extension length of fixed arm 8.

Example two

Based on the first embodiment, as shown in fig. 1 to 5, the buffer mechanism 2 includes a fixture block 12, one end of the fixture block 12 is fixedly connected with a backing plate 13, the other end of the backing plate 13 is fixedly connected with a fixing rod 14, a second clamping groove 15 is formed in a side surface of the fixing rod 14, a support rod 16 is fixedly clamped inside the second clamping groove 15, one side of the support rod 16 is fixedly connected with a spring 17, the other end of the spring 17 is fixedly connected with a joint rod 18, and the other end of the joint rod 18 is fixedly connected with the side wall of the sleeve 4 in the fixing mechanism 3;

further, one end of the fixed rod 14 is movably connected with a movable arm 19, and the other end of the movable arm 19 is movably connected with the joint rod 18;

furthermore, a first clamping groove 11 is formed in the base plate 1 at the same side as the buffering mechanism 2, the size of the first clamping groove 11 is matched with that of a clamping block 12 in the buffering mechanism 2, and meanwhile, the clamping block 12 is fixedly clamped inside the first clamping groove 11.

When the buffer mechanism 2 is used, the head of a user swings backwards, then certain pressure is applied to the buffer mechanism 2, when the buffer mechanism 2 is under the pressure, the movable arm 19 can swing, when the buffer mechanism contracts inwards, because the movable arm 19 and the spring 17 are connected with the joint rod 18, the spring 17 can be compressed to generate outward thrust, so that the whole device has a swinging effect, and a certain buffering effect is generated

The working principle is as follows: when using the device, firstly fixing the device;
