[0024] In the description of the present invention, it should be noted that the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the position or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0025] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, or integral connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of these terms in this utility model based on the specific circumstances.

[0026] like Figure 1-2 As shown, the utility model discloses a bolt with a rivet head, including a head 10, the head 10 is provided with a positioning boss 12, and the positioning boss 12 can facilitate quick positioning of the bolt, thereby improving installation efficiency; a screw 13 is provided on the positioning boss 12, and a rivet head 15 is provided at the free end of the screw, the head 10, the positioning boss 12, the screw 13 and the rivet head 15 are coaxially arranged, and the rivet head 15 is provided with a first conical groove 16 at one end away from the screw 13; by arranging the rivet head 15 at one end of the screw 13, the rivet head 15 and the thread 14 are used for double stable tightening during fixation, thereby avoiding the problem that the bolt falls off due to the vibration of the equipment, which leads to the occurrence of safety accidents.

[0027] The head 10 is provided with a second tapered groove 11 on the side away from the positioning boss 12, and the first tapered groove 16 and the second tapered groove 11 are coaxially arranged; the coaxial arrangement can facilitate better transmission of the force applied to the second tapered groove 11 to the first tapered groove 16.

[0028] The height of the head 10 is 2.95 cm to 3.25 cm.

[0029] The height of the positioning boss 12 is 5.70 cm-5.80 cm.
