【考案の詳細な説明】本考案は、ヒートガンに使用するヒータ線ホル
ダーの改良に関する。[Detailed Description of the Invention] The present invention relates to an improvement of a heater wire holder used in a heat gun.

尚、ヒートガンとは、モータフアン、ヒータを

ので、本考案で提示するのは、上記ヒータ線を保
持するためのホルダーに関する。 A heat gun is equipped with a motor fan and a heater, and the hot air generated by bringing the air sent from the fan into contact with the heater is ejected through a nozzle to bend, weld, etc. plastic materials. In place of the torch lamp, the present invention proposes a holder for holding the heater wire.

のであつた。 Needless to say, this type of holder has a honeycomb-shaped end face as shown in Fig. 2, and each hole serves as a heater wire insertion path that also serves as an air path, and the heater wire is inserted into this insertion path. However, since the conventional holder is an integrally molded product, the heater wire must be inserted into each insertion path of the honeycomb in the axial direction from the opening at one end to the opening at the other end.
However, since the heater wire is coiled, the insertion operation is extremely troublesome and complicated, and the insertion operation takes a long time, resulting in extremely inefficient operation.

そこでこの考案では、この不都合欠点に鑑み、
上記ホルダーに工夫を加え、もつてヒータ線のホ

るものである。 Therefore, in this invention, in view of this inconvenience,
The present invention is intended to greatly simplify the operation of assembling the heater wire into the holder by adding some innovation to the holder.

以下図面について実施例の詳細を述べる。 The details of the embodiment will be described below with reference to the drawings.

And, by inserting a cylindrical ceramic sleeve C onto the outermost bobbin B,
A heater wire insertion passage 3 which also serves as an air passage and has a honeycomb cross section is formed inside this sleeve.

It is formed approximately equal to the inner diameter of the cylinder of bobbin B, and
The outer diameter of the bobbin B up to the tip of the fin is the outer diameter of the cannula C.
Of course, the inner diameter is approximately equal to the inner diameter of

るものである。 As mentioned above, in the present invention, the heater wire holder is composed of independent bobbins A and B and the sleeve C, which are fitted concentrically. To assemble the heater wires, first, with the bobbins A and B and the sleeve C separated, first run the heater wires from the outside between the fins of the innermost bobbin A, and then attach the heater wires to the innermost bobbin A.
is inserted into the bobbin B, the heater wire is run along from the outside between the fins of the bobbin B as above, and then the sleeve C is inserted, which is a very simple operation that substantially This makes it possible to assemble the heater wires in the same manner as when inserting them into the conventional honeycomb-shaped heater wire insertion passages, which greatly simplifies the work of assembling the heater wires. In addition, since the structure of the bobbin mold is simplified, the mold manufacturing cost is also reduced, and the manufacturing cost of the bobbin can be kept low, which has excellent practical effects.
