Shafts 37 are rotatably installed on both sides of the inner bottom of the charging chamber 33, and the leaf springs 36 and 36 'are installed at appropriate positions of the shafts. Thus, the leaf springs 36 and 36 'have a constant trajectory in the charging chamber 33 as it rotates with the shaft 37. Therefore, when the leaf springs 36 and 36 'installed in the opposite state rotate, the space size therebetween is varied.

In addition, one end of the shaft 37 is provided with teeth 371 and 371 ′ for receiving power from the outside of the charging chamber 33, and one tooth 371 ′ arbitrarily selected among the teeth is a drive gear. The disk 40 knob 38 and the drive gear 39, which are provided outside the charging chamber 33, are integrally connected by the screw 40 which engages the 39 and inserts it into the center of the shaft.

The pinion 391 is installed between the driving gear 39 and the other gear 37 to be connected.

In the circumference of the disk-shaped knob 38, an irregular shape may be formed to enhance friction with the finger.

After setting the angle of the contact piece 36 with the disc-shaped knob 38, a control protrusion 382 protrudes in a semicircular shape on the inner surface of the disc-shaped knob 38 in contact with the side of the charger. To form.

Then, the side of the charger 32, the disk-shaped knob 38 is installed through the through hole 324 through which the square shaft 381 of the disk-shaped Novo and the stop around which the control projections 382 are joined. A plurality of grooves 325a and 325b are formed, but are formed in a circular shape.

According to the present invention having the above configuration, the shaft 37 provided in the charging chamber 32 can rotate, and the rotation thereof is performed at the same time as the rotation control of the disc-shaped knob 38.

The leaf spring 36 coupled to the axle 37 is formed as shown in FIGS. 2 and 3. Since the plate spring 36 is rotated to face each other, the outer surface of each communication device having a different size can be pressed with a bombardment.

In addition, since the shaft 37 on which the contact piece 36 is installed is fitted at both ends of the bushings 321 and 322 formed on the inner wall of the charger 32, the shaft 37 is rotated from the bushing.

The sliding gear boss 323 is projected between the bushings 321 and 322 of the charging chamber 33 in the above configuration so that the sliding gear 391 is rotatably installed by the screw 40.

In addition, a square shaft 381 of the disk-shaped knob 38 is inserted into the through hole 324 bored between the boss 323 and the bushing 322 so that the square hole 392 of the drive gear 39 is square. When fitted to the screw 40 so as not to be separated, the control projection 382 is fitted into the stop grooves (325a, 525b ...) which are dug at regular intervals around the through hole (324) and the drive gear (39) The pinion 391 and the gear 371 is engaged.
