At this time, the adjustment plate 102 will move in the direction close to the placement slot 202 under the action of the elastic force of the return spring 108, and generate reverse stress on the inclined plate 106. At the same time, the support spring 109 will also apply elastic force to the driven plate 107, so that the driven plate 107 also moves in the direction close to the placement slot 202, and push the slider 103 into the inside of the placement slot 202, so that the slider 103 is engaged with the groove 302 on the surface of the RF receiver 301, and the block 104 is engaged with the slot 303, and the RF receiver 301 is fixed inside the placement slot 202.
