When positioning the workpiece, one end of the workpiece is pushed toward the support plate 37 until it is completely parallel to the support plate 37, so that it is easy to position it in the X-axis and Z-axis directions.

[0023] The inner cavity of the mounting groove 35 is provided with a positioning assembly 36, and the positioning assembly 36 includes a mounting sleeve 361 mounted in the inner cavity of the mounting groove 35, the mounting sleeve 361 is connected to the fixing sleeve 363 via a spring 362, a fixing column 364 is mounted in the middle of the fixing sleeve 363, one end of the fixing column 364 passes through the mounting sleeve 361 and extends to the outside thereof, one end of the fixing column 364 is rotatably connected to the push column 365 via a bearing 366, and the outer side of the push column 365 is integrally connected to the push plate 367.

[0024] By rotating the two push pillars 365, the push plates 367 outside the two push pillars 365 are rotated to be perpendicular to the base 1, and then the two push pillars 365 are pushed, and then the two push pillars 365 drive the fixed pillar 364 to move toward the inner cavity of the installation groove 35 through the bearing 366, and compress the spring 362 through the fixed sleeve 363 outside the fixed pillar 364.
