[0033] The clamping plate 204 can vertically slide on one side of the vertical plate 201. By placing one end of the cutter between the clamping plate 204 and the fixed plate 202, then rotating the threaded rod 203 to lower the clamping plate 204 and clamp the cutter, then sliding the support plate 2061 according to the length of the cutter using the slide rail 205, so that the other end of the cutter is placed on the support plate 2061, then rotating the adjusting rod 2064 to lower the clamping plate 2063 along the T-shaped rod 2062, so as to clamp the other end of the cutter with the clamping plate 2063 and the support plate 2061, after fixing, deflect the protective cover 301 to cover the surrounding environment of the cutter to ensure the safety of the test environment, the protective cover 301 is made of explosion-proof tempered glass to facilitate observation of the bending change of the cutter.

[0034] Then the push plate 104 is raised by the electric push rod 103, so that the push plate 104 presses the bottom of the cutter upward to test the bending ability of the cutter. When the test is completed, the electric push rod 103 lowers the push plate 104, and the electric push rod 103 can be moved by the electric guide rail 102 to test the bending ability of the middle part and the cutting edge of the cutter. After the test is completed, the protective cover 301 is turned over, then the adjusting rod 2064 and the threaded rod 203 are rotated in turn, so that the clamping plate 2063 and the clamping plate 204 no longer clamp the cutter, then the cutter can be taken out.

When the cutter is bent from the horizontal state, the height of the bending point of the cutter can be observed through the scale plate 304. The straight plate 306 is moved above the bending point of the cutter, so that the straight plate 306 is lifted upward when the cutter is bent, so as to display the value of the cutter on the scale plate 304 by the rectangular frame 305.

[0041] During use, one end of the cutter is placed between the clamping plate 204 and the fixed plate 202, then the threaded rod 203 is rotated to clamp the cutter by the clamping plate 204, then the cutting edge of the cutter is placed on the disc 208, then the cutter is adjusted to the horizontal state by the limiting rod 207 and the disc 208, then the adjusting rod 2064 is rotated to clamp the other end of the cutter by the clamping plate 2063, after clamping, the scale plate 304 is moved to the bending point position of the cutter, and the straight plate 306 is moved above the bending point of the cutter, so that the straight plate 306 is lifted upward when the cutter is bent, then the shield 301 is deflected, and the push plate 104 is lifted upward by the electric push rod 103 to press the bottom of the cutter upward, so as to test the bending ability of the cutter.

[0042] When the cutter is bent, the straight plate 306 is lifted upward, and the rectangular frame 305 is lifted upward to display the value of the cutter on the scale plate 304. After the test is completed, the push plate 104 is lowered by the electric push rod 103, and the electric push rod 103 can be moved by the electric guide rail 102, so as to test the bending ability of the middle and cutting edge of the cutter. After the test is completed, the shield 301 is turned over, then the adjusting rod 2064 and the threaded rod 203 are rotated in turn, so that the clamping plate 2063 and the clamping plate 204 no longer clamp the cutter, then the cutter can be taken out.
