As shown in FIGS. 2 and 3, the choke holder 100 according to the first embodiment of the present invention is provided in a hollow cylindrical shape and has a holder groove 110 in which a groove groove 112 in a helical direction is formed therein. And guide housing 120 is provided in a hollow cylindrical shape is inserted and coupled to the inside of the holder case 110, the choke mounting portion 130 is mounted to the rear end of the choke 105 to the front and the back is possible to move forward and backward And a rear end cap 150 coupled to the rear end of the guide housing 120, and a front end cap 160 coupled to the front end of the guide housing 120.

Here, the slot 122 in the longitudinal direction is formed in the guide housing 120, and the through hole 135 formed through the choke mounting portion 130 in the radial direction is formed. 3, the guide member 140 is coupled to the slot 122 and the through hole 135, and both ends of the guide member 140 are grooved 112 of the holder case 110. It is interposed in (refer FIG. 6).

By this configuration, when the holder case 110 is rotated relative to the guide housing 120, the guide member 140 is moved in the helical direction along the groove groove 112, and accordingly within the guide housing 120 As the choke mount 130 moves forward and backward, the user can easily adjust the external exposure length of the choke 105 with respect to the holder case 110, and during this operation, the powder of the choke 105 is transferred to the holder case 110. It is possible to prevent the function of the choke holder 100 from being deteriorated because it does not accumulate inside the c).

When explaining each structure, first, the holder case 110 is a part which forms an external appearance, and is a part which a user grips directly. In the inner surface of the holder case 110, as shown in detail in Figures 3 and 5, the groove groove 112 having a spiral direction is formed. The groove groove 112 is provided with a guide member 140 coupled to the choke mounting portion 130 to be described later to allow the choke mounting portion 130 to move forward or backward in the guide housing 120. This will be described in detail later.

The holder case 110 may be injection molded using a synthetic resin such as ABS (Acrylonitrile Butadiene Styrene) resin having durability. In addition, since the holder case 110 is made of a transparent or translucent material, the user can identify the length of the choke 105 moving forward or backward from the inside of the holder case 110, and thus, the replacement time of the choke 105. Can be determined.

Meanwhile, as illustrated in FIGS. 3 and 4, the guide housing 120 is provided in a hollow cylindrical shape, and a pair of slots 122 are formed along the longitudinal direction. The guide housing 120 not only serves to guide the movement of the choke mounting portion 130, but also has a structure that covers the remaining portion of the choke 105, except for the portion exposed to the outside, the powder of the choke 105 The inner case of the holder case 110, in particular, serves to block the phenomenon accumulated in the groove groove (112).

The pair of slots 122 formed in the guide housing 120 are provided in parallel with each other, as shown in FIG. 3. More precisely, they are provided symmetrically with respect to the axis of the guide housing 120. The slot 122 is a portion through which the guide member 140 penetrated and coupled to the choke mounting portion 130 to be described later, and the choke mounting portion 130 when the holder case 110 is relatively rotated with respect to the guide housing 120. Ensures accurate forward and reverse movement in the guide housing 120.

On the other hand, the choke mounting portion 130, as shown in Figure 4, the choke 105 is a portion directly coupled, the choke mounting portion 130 is inserted into the guide housing 120, and then guide member 140 Is supported in the guide housing 120.

Referring to the configuration of the choke mounting portion 130 in more detail, the choke mounting portion 130, as shown in Figure 3, the mounting member 131 forming a basic frame, and the rear end of the choke 105 is fixedly coupled It includes a fixing member 133.

Mounting member 131 is provided in a cylindrical shape having an outer diameter substantially the same as the inner diameter of the guide housing 120, the through hole 135 for coupling the guide member 140 in the radial direction is formed.

The fixing member 133 is formed to extend from the outer side of the front end of the mounting member 131, and is a part to which the rear end of the choke 105 is partially inserted and coupled. As shown in FIG. 3, the fixing member 133 may be formed by cutting a portion of the fixing member 133. That is, the fixing member 133 is cut and formed so as to slightly open to the outside when the choke 105 is inserted, thereby facilitating the fastening of the choke 105 to the fixing member 133.

Since the fixing member 133 is made of a synthetic resin material having a slight restoring force, when the rear end portion of the choke 105 is pinched between the fixing members 133, the fixing member 133 presses the choke 105. It can be retracted to reinforce the fixing force of the choke 105, and by this structure, the choke mounting portion 130 to which the choke 105 is coupled can be easily introduced into the guide housing 120.

On the other hand, as described above, the choke mounting portion 130 may be supported in the guide housing 120 by the guide member 140.

As shown in FIG. 4, the guide member 140 is coupled to the through hole 135 and the pair of slots 122 formed in the choke mounting unit 130. However, it must be coupled to protrude slightly from the pair of slots 122. Therefore, the length of the guide member 140 of the present embodiment, as shown in Figure 6, slightly longer than the outer diameter of the guide housing 120, the groove groove 112 and the groove of the inner diameter of the holder case 110 It is provided to be shorter than the inner diameter between the grooves (112).

As shown in FIG. 3, the guide member 140 is provided in a pin shape having a diameter corresponding to the inner diameter of the through hole 135 formed in the choke mounting unit 130, and the choke mounting unit 130 may be formed. It may be made of a durable metal material to prevent breakage or bending during the forward and backward operations.

By this configuration, the choke mounting portion 130 is introduced into the guide housing 120, and then the guide member 140 is coupled to pass through the through hole 135 and the pair of slots 122 of the choke mounting portion 130. After applying the force to the guide member 140 along the longitudinal direction of the slot 122, the choke mounting portion 130 to which the choke 105 can be coupled may move forward or backward.

Meanwhile, as described above, when the guide housing 120 is rotated relative to the holder case 110 (that is, when the holder case 110 and the guide housing 120 are turned in opposite directions), the choke of the present embodiment is used. The mounting portion 130 may move forward or backward, thereby adjusting the external exposure length of the choke 105 coupled to the choke mounting portion 130.

Hereinafter, this operation principle will be described with reference to FIG. 6.
