The two clamping plates 403 are respectively threadedly connected with two thread grooves opened in opposite directions on the first double-headed screw 404, and one end of the first double-headed screw 404 is fixedly connected to the output shaft of the first motor 405, and the first motor 405 is fixedly installed on the support plate 401;

[0028] The distance adjustment component 5 includes a second slide groove 501 symmetrically opened on the base 1, a slider 502 is installed at the bottom end of the movable support platform 3, the slider 502 is slidably installed inside the second slide groove 501, and a second double-headed screw 503 is rotatably installed inside the two second slide grooves 501, and the two sliders 502 are respectively threadedly connected with two thread grooves opened in opposite directions on the second double-headed screw 503, and one end of the second double-headed screw 503 is fixedly connected to the output shaft of the second motor 504, and the second motor 504 is fixedly installed on the base 1. The three support plates 401 support the rod, and the second motor 504 is turned on to rotate the second double-headed screw 503. Since the sliders 502 on the two movable support platforms 3 are respectively threadedly connected with the two thread grooves opened in opposite directions on the second double-headed screw 503, the support plates 401 on both sides are driven to move relative to each other, which is convenient for supporting and processing rods of different lengths;

[0029] The angle adjustment component 6 includes a connecting block 603 fixedly installed at the bottom end of the support plate 401, and rotating shafts 604 are symmetrically installed on both sides of the connecting block 603.
