3. The multi-angle rotatable table top clamping device according to any one of claims 1-2, wherein: the top of the base (1) is provided with a storage groove (103) for storing tools.
4. The multi-angle rotatable table top clamping device of claim 3, wherein: the chopping block (102) for hammering the workpiece is arranged at the top of the storage groove (103), the length of the chopping block (102) is smaller than that of the storage groove (103), and the width of the chopping block (102) is the same as that of the base (1).
5. A method of using the multi-angle rotatable table top clamping device of claim 2, wherein: the method comprises the following steps:
s1, adjusting the rotation angle of the base (1) in the Z-axis direction: unscrewing the second hand wheel (201), rotating the base (1) to enable the second hand wheel to rotate along the Z-axis direction, and re-screwing the second hand wheel (201) after adjustment is completed;
s2, adjusting the rotation angle of the sleeve seat (3) in the Y-axis direction: unscrewing the first hand wheel (101), rotating the sleeve seat (3) to a horizontal position by referring to the bubble level meter (302), or rotating the sleeve seat (3) to a specified angle by referring to the relative position of the first angle mark (1041) and the first angle scale (105), and re-screwing the first hand wheel (101) after adjustment is completed;
s3, installing a workpiece: the workpiece is stretched into the clamping sleeve (4), and the upper clamping block (405) and the lower clamping block (402) are driven to move through the upper clamping hand wheel (404) and the lower clamping hand wheel (401) respectively so as to adjust the size of the jaw (403), so that the workpiece is clamped in the clamping sleeve (4);
s4, processing the workpiece;
s5, when the rotation angle of the workpiece in the X-axis direction needs to be changed, unscrewing the third hand wheel (301), referring to the relative position of the second angle mark (4041) and the second angle scale (406), driving the workpiece to rotate to a specified angle by rotating the clamping sleeve (4), and re-screwing the third hand wheel (301) after adjustment is completed;
s6, continuously processing the workpiece;
s7, repeating S2 or S5 according to the processing process until the processing is completed.
