[0026] Specifically, refer to Figure 1 The top of the processing table 1 is fixedly connected with two symmetrically distributed linear slide rails 11, and a linear motor 12 is arranged on the outer side of the linear slide rail 11. The top of the linear motor 12 is fixedly connected with a hydraulic rod 13, and the output shaft of the hydraulic rod 13 is fixedly connected with a mounting plate 14. The relatively inner sides of the two mounting plates 14 are rotatably connected with a one-way threaded rod 15, and the outer side of the one-way threaded rod 15 is threadedly connected with the support plate 2.
