[0031] The preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings, so that it is easy for a person skilled in the art to implement these embodiments. However, the present invention can also be implemented in various forms, so the present invention is not limited to the embodiments described below. In addition, in order to more clearly describe the present invention, parts that are not connected to the present invention will be omitted from the accompanying drawings.

[0032] An easily adjustable vehicle seat headrest, comprising: a headrest 1, a backrest 2, a plug rod 3, a rod sleeve 4, an adjustment box 5, a spring 6, a locking member, and a toggle block 8;

[0033] As Figure 2 shown, two parallel first jacks 22 are provided inside the backrest 2, and a groove 21 is provided at the top of the two first jacks 22;

[0034] As Figure 3 shown, two parallel plug rods 3 are connected to the bottom of the headrest 1; the plug rods 3 are inserted into the rod sleeve 4; the rod sleeve 4 is fixed in the first jack 22;

[0035] Both sides of the adjustment box 5 are respectively connected to the rod sleeve 4, and the adjustment box 5 is located in the groove 21;

[0036] As Figure 4 shown, a top cover 51 is connected to the top of the adjustment box 5;

[0037] As Figure 5 shown, each plug rod 3 is provided with a flat section 31, and a plurality of through holes 311 are provided on the flat section 31;

[0038] As Figure 7 shown, a through groove 511 is provided on the top cover 51;

[0039] As Figures 9 - 11 shown, a conduction tube 52 is provided inside the adjustment box 5, both ends of the conduction tube 52 are respectively communicated with the rod sleeve 4, and a notch 521 is provided in the middle of the conduction tube 52;

[0040] The spring 6 is arranged in the notch 521;

[0041] There are two locking members, each including: a moving rod 71, a positioning rod 72, and a vertical rod 73;

[0042] The moving rod 71 is located inside one end of the conduction tube 52, a positioning rod 72 is connected to the tail of the moving rod 71, and the positioning rod 72 penetrates into the spring 6; a vertical rod 73 perpendicular to the moving rod 71 is connected to the positioning rod 72, and a second jack 731 is provided at the top of the vertical rod 73;

[0043] The bottom of the toggle block 8 is connected with a short rod 81, the short rod 81 passes through the through groove 511 and cooperates with the second jack 731.

[0044] Furthermore, the head of the moving rod 71 is set to be ball-shaped, which is convenient for it to pass through the through holes 311 to fix the plug rod 3.

[0045] Furthermore, as Figure 11As shown, a corrugated strip 82 is provided on one side surface of the toggle block 8 to increase the friction force and facilitate the pinching by fingers.
