1. A light-emitting diode (LED) lamp bulb with crimped fixed wires, comprising a lamp base (1) and a shell (2) connected to the lamp base (1), and further comprising a stem assembly (3), wherein the stem assembly (3) comprises a plastic seat (31), and a first metal supporting wire (32), an LED bar (33) and a second metal supporting wire (34) which are electrically connected with each other in sequence; the plastic seat (31) is connected to an opening portion of the shell (2); one end of the plastic seat (31) is provided with a cavity (311) having an opening, and the other end is provided with a raised tongue portion (312); the raised tongue portion (312) is at least provided with a first wire guide hole (313) and a second wire guide hole (314); the first wire guide hole (313) and the second wire guide hole (314) are both communicated with the cavity (311); one end of the first metal supporting wire (32) is electrically connected to the LED bar (33) through the first wire guide hole (313); one end of the second metal supporting wire (34) is electrically connected to the LED bar (33) through the second wire guide hole (314); the other ends of the first metal supporting wire (32) and the second metal supporting wire (34) are both electrically connected to the lamp base (1);
the first metal supporting wire (32) is fixed by means of being crimped with an outer side of the first wire guide hole (313), and/or the second metal supporting wire (34) is fixed by means of being crimped with an outer side of the second wire guide hole (314);
the raised tongue portion (312) is provided with a first side surface (315) and a second side surface (316); and the first side surface (315) and the second side surface (316) are both provided with fixing regions (317); the first metal supporting wire (32) is fixed by means of being crimped with the fixing region (317) of the first side surface (315) and/or the second side surface (316) to narrow the first wire guide hole to clamp the first metal supporting wire (32);
wherein each of the first metal supporting wire (32) and the second metal supporting wire (34) comprises an antiskid section (4) with concave-convex surfaces configured to increase friction between the first and second metal supporting wires and walls of the first and second wire guide holes, respectively.
