Fig. 4 is a schematic view of the use of the thermal nailer of fig. 1. Fig. 5 is a schematic circuit diagram of the thermal nailer of fig. 1. Referring to fig. 1 to 5, the hot nailing machine of the present embodiment includes a main body 10, two heat conducting members 20, an electric storage unit 30, a circuit 40, and a switch 50.

The body 10 includes a head 11 and a grip 12. The two heat conducting members 20 are adapted to be connected to two leg ends 61 of a patch 60, one end of each heat conducting member 20 is inserted through the head 11, and the other end is exposed outside the body 10. Each of the heat-conducting members 20 includes a guide rod 21, an insulating tube 22 fitted over the guide rod 21, and a metal cylinder 23 fitted over the insulating tube 22. Each metal cylinder 23 has a radial hole 231 and an axial hole 232, the axial hole 232 is disposed on the end surface of the metal cylinder 23 and is suitable for the insertion of the foot end 61 of the patch nail 60, and each metal cylinder 23 provides a heat dissipation effect.

The electric storage unit 30 is provided in the grip portion 12 and has a voltage value of not more than 6 volts. The electric storage unit 30 may include two or more disposable batteries connected in series, and the voltage value of each disposable battery is 1.5 volts. The power storage unit 30 may include one or more secondary batteries, which may be lithium batteries or nickel metal hydride batteries, and have a voltage value of 3.7 volts.

The circuit 40 includes a first lead 41 and a first resistor 42 electrically connected between one of the two heat-conductive members 20 and the electric storage unit 30, and a second lead 43 and a second resistor 44 electrically connected between the other heat-conductive member 20 and the electric storage unit 30. The first lead 41 is electrically connected to the negative electrode of the electric storage unit 30, the second lead 43 is electrically connected to the positive electrode of the electric storage unit 30, and the first lead 41 and the second lead 43 respectively penetrate through the guide rods 21 of the heat conducting members 20 and are bent to hook the diameter holes 231 of the metal cylinders 23. Both the first resistor 42 and the second resistor 44 can have a resistance value between 0.06 ohm and 0.2 ohm, and in addition, the first resistor 42 and the second resistor 44 can have the same resistance value.

The switch knob 50 is slidably disposed on the grip 12 and can be switched between an energized position and a de-energized position, so that the current supplied by the power storage unit 30 can flow to each of the heat conducting members 20 through the first conducting wire 41 and the first resistor 42, and the second conducting wire 43 and the second resistor 44, respectively, to generate heat energy and heat the patch 60.
