[0027] See also Figure 1-6 An L-rod 305 is hinged on one side of the workbench 101 , one end of the L-rod 305 is hinged to the other end of the mounting rod 304 , and a pull rod 306 is hinged on the other end of the L-rod 305 , and a slide groove 307 is provided on the surface of the pull rod 306 .

[0031] See also Figure 1-6 The placement mechanism 4 includes a rotating shaft 401 rotatably connected to the top of the workbench 101, the rotating shaft 401 is coaxially arranged with the placement wheel 314, and the upper end of the rotating shaft 401 passes through the placement wheel 314, the inner edge of the placement wheel 314 is fixedly connected to the surface of the rotating shaft 401, the inner wall of the rotating shaft 401 is rotatably connected with a connecting shaft 402, and the upper end of the connecting shaft 402 passes through the rotating shaft 401 and is fixedly connected with a knob 403.

[0032] The inner wall of the connecting shaft 402 is slidably connected with a limiting plate 406 , one end of which passes through the connecting shaft 402 and the rotating shaft 401 in sequence, and the cross-sectional shape of the limiting plate 406 is a right triangle, and a second spring 404 is fixedly connected between the other end of the limiting plate 406 and the inner wall of the connecting shaft 402 .

[0033] An extrusion groove 405 is provided at the bottom of the connecting shaft 402, an annular protrusion is provided on the surface of the rotating shaft 401, and a top plate 407 is slidably connected to the inner wall of the annular protrusion, the top of the top plate 407 penetrates the annular protrusion, one side of the top plate 407 penetrates the rotating shaft 401 and is fixedly connected to a trigger block 408 located inside the extrusion groove 405, a wedge surface is provided on the top of the trigger block 408, and a third spring 409 is fixedly connected between the bottom of the trigger block 408 and the bottom of the rotating shaft 401;

[0034] The mounting hole on the blade is passed through the rotating shaft 401 so that the placement wheel 314 supports the blade, and then the knob 403 is rotated to drive the limit plate 406 to move to the penetration point with the rotating shaft 401. In this process, the limit plate 406 is driven by the second spring 404 to penetrate from the inside of the connecting shaft 402 and the rotating shaft 401 to the top of the blade, and the extrusion groove 405 moves to the top of the trigger block 408. At this time, the trigger block 408 is driven to move upward under the action of the third spring 409, and then the top plate 407 can be driven to move upward synchronously to achieve the limit of the blade position through the top plate 407 to drive the blade to cooperate with the limit plate 406, so as to facilitate the punching process;

[0035] When disassembling, it is only necessary to rotate the knob 403 in the opposite direction so that the limit plate 406 is squeezed by the inner wall of the place where the limit plate 406 and the rotating shaft 401 pass through, causing it to shrink to the inside of the connecting shaft 402. At the same time, the inner wall of the extrusion groove 405 squeezes the inclined surface of the trigger block 408 to drive the top plate 407 to move downward. At this time, the limit on the blade is released and the blade can be removed. Compared with the traditional method that requires the staff to use fasteners for fastening, this method is simpler and can improve the efficiency of placing and removing the blade.

[0036] Working principle: the mounting hole on the blade passes through the rotating shaft 401 so that the placement wheel 314 supports the blade, and then rotating the knob 403 can drive the limit plate 406 to move to the point where it penetrates the rotating shaft 401. In this process, the second spring 404 drives the limit plate 406 to penetrate from the inside of the connecting shaft 402 and the rotating shaft 401 to the top of the blade, and at the same time, the extrusion groove 405 moves to the top of the trigger block 408. At this time, under the action of the third spring 409, the trigger block 408 is driven to move upward, and then the top plate 407 can be driven to move upward synchronously to achieve the limit of the blade position through the top plate 407 to drive the blade to cooperate with the limit plate 406, so as to facilitate punching processing. When disassembling, you only need to rotate the knob 403 in the opposite direction to release the limit and remove the processed blade.
