Furthermore, the number of the thread end clamping holes is four, and the four thread end clamping holes are uniformly distributed on the bottom plate.

Furthermore, the lower end face of the bottom plate is provided with four positioning bulges, and the four positioning bulges are uniformly distributed on the bottom plate. It is thus clear that, after carrying out the point to the wire end of a thread and gluing the solidification, the lower terminal surface of bottom plate may remain the surplus glue that oozes, when placing inductance support on the platform, inductance support can be owing surplus glue that the bottom plate epirelief came out appears and unstable problem, consequently the lower terminal surface of bottom plate is protruding through evenly being provided with four location, makes there is certain width between the lower terminal surface of bottom plate and the platform, and then can avoid the surplus glue that the protrusion came well right the utility model discloses it is right to cause the problem of unstable placement.

Further, the upper end face of the bottom plate is provided with an arc-shaped groove. Therefore, after the inductance coil is hooped on the isolation clamping plate, the arc surface on the outer side of the inductance coil can be matched with the arc-shaped groove.

Further, keep apart the cardboard and include support bar and locating plate, the support bar is vertical to be set up on the bottom plate, the locating plate sets up on the support bar, inductance coils cramps on the locating plate.

Furthermore, the locating plate is made by the plastic material, be provided with the open slot on the locating plate, the top of locating plate is provided with spacing arch, the open slot is close to spacing arch, spacing arch top is leaned on the inductance coils. Therefore, the locating plate is made of a plastic material, the top of the locating plate has certain elasticity, when the inductance coil is sleeved on the locating plate, the limiting protrusions can abut against the inductance coil, the top end of the locating plate can be extruded by the inductance coil to be bent and deformed, the open slot can be narrowed, and therefore the inductance coil is clamped on the locating plate.
