When the third motor 218 is started, the sixth fixing block 213 can be moved left and right as a whole through the thread, facilitating the processing of hole positions at different locations. When the material is clamped by the support plate 208, the motor 105 drives the gear 106 to rotate. The gear 106 meshes with the first gear 107 to make the threaded rod 108 rotate. At the same time, the threaded rod 108 is rotationally connected to the first fixing plate 104, and the bottom of the threaded rod 108 is rotationally connected to the table body 101. When the motor 105 is started, the threaded rod 108 rotates and is threadedly connected to the fixing plate 103, so that the fixing plate 103 can move up and down along the outer wall of the support column 102 as a whole, facilitating the processing of some large materials. At the same time, a first fixing block 110 is fixedly connected to the top of the fixing plate 103, and a first motor 113 is fixedly connected to the top of the first fixing block 110.

The spring 305 at the bottom of the third fixing plate 307 is compressed, and the fixing column 304 limits the spring 305 to prevent the spring 305 from shifting. When the material reaches the specified position, the spring 305 rebounds to lift the third fixing plate 307. At this time, the cylinder 206 releases the material.The motor three 218 drives the fixed block six 213 to reset as a whole. At this time, the motor four 309 operates to drive the threaded rod three 310 to rotate. The threaded rod three 310 is threadedly connected to the slider two 302.
