[0034] The specific structure of this application includes:
[0035] Base 1, on which an assembly groove 2 is opened. The assembly groove 2 is convenient for the subsequent assembly of other components. Specifically, the assembly groove 2 is composed of outer edges to form a blocking member, thereby ensuring the stability during the subsequent assembly of components;
[0036] The limit cover 3 is installed in the assembly groove 2, and a receiving cavity 301 is arranged inside the limit cover 3. An opening 302 is arranged on one side of the limit cover 3. The limit cover 3 is used to provide a processing space for facilitating the placement of the resonant column and then processing it. Among them, the opening 302 is for facilitating the picking and placing of the resonant column to ensure the processing effect;
[0037] The pressing head 4, one end of the pressing head 4 passes through the limit cover 3 and extends into the receiving cavity 301. The outer side of the pressing head 4 is threaded. The up and down movement of the pressing head can realize the pressing of the resonant column, so as to complete the shaping of the corresponding workpiece;
[0038] The positioning column 5, one end is installed in the base 1, and the other end extends into the pressing head 4. The positioning column 5 is used to limit the workpiece to prevent the resonant column from shaking during the shaping process.
[0039] Regarding the structure of the present application, the resonant column is placed through the opening 302, and then the pressing head 4 is twisted so that the pressing head 4 abuts against the resonant column, and the positioning column 5 extends into the resonant column, which can ensure the stability of the resonant column during processing.
[0040] In order to ensure the stability of the resonant column after being placed in the receiving cavity 301, a groove 6 is opened inside the base 1 of the present application, and a support column 7 is installed inside the groove 6 to support the corresponding workpiece to be processed through the support column 7.
