[0033] A gear 22 is fixedly mounted on the front end of the rotating shaft 21, a rack 23 is meshedly connected to the lower part of the gear 22, and a slide groove 11 for the rack 23 to move is provided on the workbench 1 at a position corresponding to the rack 23;

[0034] A limiting mechanism is provided on the front vertical plate 2, which includes a fixed plate 41 fixedly mounted on the vertical plate 2 and a movably connected ratchet bar 42, the right end of the fixed plate 41 is rotatably connected to the right end of the ratchet bar 42, and the left end of the fixed plate 41 is connected to the left end of the ratchet bar 42 via a spring 43;

[0035] An equal-dividing disk 44 fixedly mounted on the rotating shaft 21 is provided below the ratchet strip 42 , and four notches 45 are evenly spaced on the circumferential surface of the equal-dividing disk 44 .

[0036] Optionally, in the above technical solution, the positioning assembly includes two positioning plates 31 fixedly mounted on the rotating shaft 21 , a bidirectional screw rod 32 is rotatably connected inside the two positioning plates 31 , and two adjustment columns 33 are connected to the external threads of the positioning plates 31 .

[0037] Optionally, in the above technical solution, a positioning seat 34 is fixedly installed on one side of the two adjustment columns 33 away from the rotating shaft 21 , an opening is provided on the opposite side of the two positioning seats 34 , and the positioning seat 34 is slidably connected to the positioning plate 31 through a telescopic rod 37 .

[0038] Optionally, in the above technical solution, a threaded hole is provided at the top of the positioning seat 34 , a bolt 35 is threadedly connected to the threaded hole, and an adjustment seat 36 is fixedly installed at the bottom of the bolt 35 .

[0039] Optionally, in the above technical solution, a driving motor 30 is fixedly installed on the outside of the rear positioning plate 31 , and an output end of the driving motor 30 passes through the positioning plate 31 and is fixedly connected to the bidirectional screw rod 32 .

[0040] Optionally, in the above technical solution, the rack 23 is fixedly connected to the driving rod 24 .

[0041] In the initial state, the connecting line of the left and right notches 45 is parallel to the upper surface of the workbench 1 , and there is a 90-degree angle between two adjacent notches 45 , so as to make the sheet material parallel and vertical to the bottom surface.

[0042] The gear 22, the dividing plate 44 and the rotating shaft 21 are coaxially arranged;

[0043] The width of the chute 11 is adapted to the width of the rack 23 to reduce the deviation of the rack 23;

[0044] Wherein, a rubber pad is provided at the bottom of the adjustment seat 36 .

[0045] Working principle:

[0046] When in use, place the sheet between the two positioning seats 34, start the drive motor 30 to drive the two bidirectional screws 32 to rotate, so that the two adjustment columns 33 drive the two positioning seats 34 to move relative to each other, clamp the sheet, and then rotate the bolt 35 to press the adjustment seat 36 against the upper surface of the sheet to achieve secondary fixation and improve the fixing effect;

[0047] At this time, the upper surface of the sheet can be processed. After the processing is completed, the moving drive rod 24 drives the rack 23 to move, so that the meshing gear 22 rotates counterclockwise, driving the parts on the rotating shaft 21 to rotate synchronously, thereby driving the sheet on the positioning seat 34 to rotate.

[0048] When the sheet needs to be made perpendicular to the workbench 1 (i.e. flipped 90 degrees), the rack 23 is moved to a position where the ratchet 42 extends into the notch 45 adjacent to the initial notch 45;

[0049] When the sheet needs to be made parallel to the workbench 1 (ie, flipped 180 degrees), the rack 23 is moved to a position where the ratchet bar 42 extends into a notch 45 that is not adjacent to the initial notch 45 .

[0050] The above description is only the preferred implementation of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
