During the passing process, the inclined surface 403 of the support plate 402 on the outer support component of the positioning cylinder 303 abuts against the inner wall of the positioning hole 301. During the abutment process, the support plate 402 is pushed toward the inside of the installation groove 401 for contraction movement and the first spring 503 is deformed by force to generate elastic force. After the positioning cylinder 303 is pushed, the elastic force of the first spring 503 pushes the support plates 402 on each group of support components to abut against the inner side of the positioning hole 301, so as to support the placed bottom plate boss 201, the capacitor ceramic body 202 and the capacitor pressure plate 203, so as to facilitate the more stable use of the bottom plate boss 201, the capacitor ceramic body 202 and the capacitor pressure plate 203.

[0041] In this scheme: a radio frequency laser capacitance adjustment device comprises the following steps:

[0042] During the use of the RF laser capacitor, the capacitor ceramic body 202 and the capacitor pressure plate 203 are stacked on the capacitor adjustment base 101 in sequence, and during the stacking process, the capacitor ceramic body 202 is abutted against the bottom plate boss 201 on the capacitor adjustment base 101;

[0043] After the capacitor ceramic body 202 and the capacitor pressing plate 203 are stacked, the bottom plate boss 201, the capacitor ceramic body 202 and the capacitor pressing plate 203 are limited and supported by the positioning component, the supporting component and the limiting component to assist the stable use of the RF laser capacitor. In the process of adjusting the capacitor, the capacitor pressing plate 203 and the bottom plate boss 201 are controlled by the amount of the two fan-shaped overlapping areas when the capacitor ceramic body 202 is isolated. The capacitor pressing plate 203 is rotated to obtain different capacitance values, and the circuit startup capacitance path of the laser is easily corrected, which has a significant promoting effect on the production efficiency of the laser during long-term use.

In the process of passing, the inclined surface 403 of the support plate 402 on the outer support component of the positioning cylinder 303 abuts against the inner wall of the positioning hole 301. In the process of abutting, the support plate 402 is pushed toward the inside of the installation groove 401 for contraction movement and the first spring 503 is deformed by force to generate elastic force. After the positioning cylinder 303 is pushed, the elastic force of the first spring 503 pushes the support plates 402 on each group of support components to abut against the inner side of the positioning hole 301, so as to support the placed bottom plate boss 201, the capacitor ceramic body 202 and the capacitor pressure plate 203, so as to facilitate the bottom plate boss 201, the capacitor ceramic body 202 The capacitor pressure plate 203 is more stably used, and after the support is completed, the T-bolt 603 is passed through the through hole 602 of the positioning tube 303 and threadedly connected with the thread groove 601. After the T-bolt 603 is connected, the driving ring 702 is rotated. During the rotation of the driving ring 702, the driving ring 702 is meshed with the thread on the outer side of the T-bolt 603 to make the driving ring 702 move toward the annular baffle 304 on the T-bolt 603. During the movement, the second spring 701 is compressed and deformed to generate elastic force. The elastic force of the second spring 701 pushes the annular baffle 304 and the upper end of the capacitor pressure plate 203 to be pressed against each other, and the stacked and supported bottom plate boss 201, the capacitor ceramic body 202 and the capacitor pressure plate 203 are squeezed and limited, which is convenient for the bottom plate boss 201, the capacitor ceramic body 202 and the capacitor pressure plate 203 to be more stably used.
