The cylinder 101 is fixed to the frame 4 by bolts, the cylinder 101 and the cylinder connecting block 102 are fixedly connected by bolts, the cylinder connecting block 102 and the internal stamping block 103 are fixedly connected by bolts, the internal stamping block 103 is cooperatively arranged in the external stamping block 105 (a blind hole is opened in the center of the external stamping block 105), the stamping spring 104 is sleeved on the internal stamping block 103, and its bottom end is in contact with the external stamping block 105, wherein the external stamping block 105 is cooperatively arranged on the frame 4, the frame 4 is provided with a through hole, the external stamping block 105 is cooperatively arranged in the through hole, and can move up and down relative to the frame 4.

[0023] The punching mechanism 2 is arranged at the middle position of the frame 4 and is located below the stamping mechanism 1. The punching mechanism 2 includes a contact head 201, an outer punch connection block 202, an inner punch 203, an outer punch 205, an inner spring 204 and an outer spring 206. There are three contact heads 201, two of which are screwed on the outer punch connection block 202 at the top of the outer punch 205 (the outer punch connection block 202 and the outer punch 205 are connected by a fixing nail), and the remaining one is screwed on the top of the inner punch 203; a punching punch 207 is welded and fixed on the outer punch 205. A stamping punch 208 is welded on the inner punch 203; the inner spring 204 is sleeved on the inner punch 203, and the inner punch 203 is cooperatively arranged inside the outer punch 205 (a blind hole is opened in the outer punch 205), the bottom end of the inner spring 204 is in contact with the inside of the outer punch 205, the outer spring 206 is sleeved on the outer punch 205, and the outer spring 206 and the outer punch 205 are both arranged on the frame 4 (a step hole is opened in the frame 4, the bottom of the external spring 206 is in contact with the step hole, and the outer punch 205 is cooperatively arranged in the step hole), and can move up and down relative to the frame 4.

[0024] The test paper platform 5 includes a platform base 501, a platform surface 503 and a platform through hole 502. The platform base 501 is arranged at the bottom of the frame 4, the platform surface 503 is fixedly arranged on the platform base 501, and the platform through hole 502 is arranged at the center of the platform surface 503 and is located directly below the punching mechanism 2.

[0025] The push plate mechanism 3 is arranged at the bottom position of the frame, and the push plate mechanism 3 includes a push plate 306, a slide rail 301, a positioning head 302, a positioning spring 303 and a test paper holder 304. The push plate 306 is fixed on the slide rail 301, and positioning grooves are arranged on the two side walls of the push plate 306. A plurality of test paper holder placement holes for placing the test paper holder 304 are opened on the top of the push plate 306.

The push plate 306 can be positioned on the slide rail 301 through the positioning head 302, thereby realizing the precise positioning of the test paper holder.

[0026] Working process:

[0027] The inner cylinder of the cylinder 101 extends out, and drives the inner punch block 103 to move downward through the cylinder connecting block 102. At this time, due to the existence of the punch spring 104, the outer punch block 105 is driven to move downward together; the inner punch block 103 and the outer punch block 105 are respectively in contact with the contact head 201, and the inner punch 203 and the outer punch 205 move downward together. At this time, the punching punch 208 on the inner punch 203 has not yet extended the punching punch 207 on the outer punch 11 (the punching punch 207 is sleeved on the outside of the punching punch 208), thereby realizing the punching action of the test paper on the test paper platform 5. When the inner cylinder of the cylinder 101 runs to a certain extent, the outer spring 206 reaches the limit of compression, and the outer punch 205 no longer moves. At this time, the inner punch 203 drives the punching punch 208 to continue to move downward under the action of the inner punch block 103, thereby realizing the test paper being pressed tightly on the test paper holder 304.
