The end of the reinforcing plate 7 is provided with a rubber pad 9 in contact with the inner side of the support seat 6, the inner side of the support seat 6 is provided with anti-slip lines 14 relative to the rubber pad 9, the overall shape of the anti-slip lines 14 is a circular ring structure with the shaft hole 13 as the center, the inner wall of the fixed frame 5 is symmetrically provided with a clamping pad 10, and the inner end of the clamping pad 10 is connected to the inner wall of the fixed frame 5. The spring 12 is arranged between the inner wall of the fixed frame 5.

[0004] The deficiency of the above-mentioned patent technical solution is that different size specifications of the same electronic component product may exist, such as capacitors and resistors, whose capacitance and resistance values are related to their own volume, so there will be products of different sizes.

Since the connecting shaft is also rotatably connected to the shaft hole of the support seat, when the clamping force is not enough, the product may fall off the fixed frame during the turning process.
