10. The method for using the jig for preventing the surface damage of the workpiece as set forth in claim 1, wherein: the method comprises the following steps:
01. the workpiece is placed in the clamping seat (101) in a handheld mode, and the power supply of the driving motor (5) is connected through the control device;
02. when the driving motor (5) rotates, the driving motor (5) drives the two adjusting rods (6) to synchronously rotate through the gear;
03. when the clamping end face of the clamping block (2) is not contacted with a workpiece, the adjusting rod (6) can drive the prestress adjusting frame assembly (3) to move towards the workpiece through the movable threaded hole (3021), so that the clamping block (2) moves towards the workpiece to clamp and fix the workpiece;
03. when the clamping end face of the clamping block (2) contacts a workpiece, the right side linkage block (302) continues to move towards the workpiece at the moment, but the left side moving block (301) does not move under the obstruction of the workpiece, so that the whole prestress adjusting frame assembly (3) longitudinally extends;
04. when the prestress adjusting frame assembly (3) is longitudinally extended integrally, the fixed cylinder (401) and the support ring (405) can jointly extend the stress tension spring (4011), so that clamping and fixing force can be applied to a workpiece through the stress tension spring (4011);
05. when the application range of clamping force needs to be adjusted, only the adjusting nut is needed to rotate the adjusting ring (404), and the adjusting ring (404) moves on the surface of the cylinder body of the adjusting cylinder (402) through the adjusting threaded hole (4041), so that the initial elongation of the stress tension spring (4011) is changed;
06. when the adjusting ring (404) moves up and down, the linkage rod (4051) of the support ring (405) can drive the positioning rod (403) to move up and down synchronously to change the initial scale overlapping position of the positioning rod (403) and the top view reading block (304), so that the accuracy of scale display of the positioning rod (403) in use is ensured;
07. after clamping and fixing are completed, the workpiece can be processed;
08. after the machining is finished, the control device controls the driving motor (5) to rotate reversely to loosen the workpiece, and then the workpiece can be taken down.
