[0032] like Figure 1 , Figure 2 as well as Figure 4 As shown, the scraping mechanism includes a movable ring 6, an elastic petal 7, a rubber scraper sleeve 601 and a rubber scraper strip 701; the number of the elastic petals 7 is several, and the several elastic petals 7 are fixedly installed in a ring array around the top of the movable ring 6, and the tops of the several elastic petals 7 are fixedly connected to a rubber scraper strip 701, and the several rubber scraper strips 701 are surrounded to the rod surface of the extension rod 3, and the inner ring wall of the movable ring 6 is fixedly installed with a rubber scraper sleeve 601 that adapts to the outer wall of the suction cylinder 1.

[0033] Through the multi-petal elastic petals 7, when the extension rod 3 is scraping material, it is in a closed state, so that the rubber scraper strip 701 surrounds the extension rod 3 on all sides; in conjunction with the design of the tapered connecting cover 2 with an outer diameter that gradually increases from top to bottom, the movable ring 6 moves to the position of the suction cylinder 1. When scraping material from the outer wall of the suction cylinder 1, the tapered connecting cover 2 squeezes the elastic petals 7 to open them, and the entire scraping mechanism can continue to move downward.

[0034] The elastic flap 7 is made of spring steel.

[0035] like Figure 4-8 As shown, the vertical driving mechanism includes an end seat 18, a screw rod 19, a nut 13 and a guide block 12; the number of the end seats 18 is two, and the two end seats 18 are fixedly installed at the top and the bottom of the inner cavity respectively, the screw rod 19 is rotatably installed between the two end seats 18, the nut 13 is threadedly connected to the screw rod 19, the guide block 12 is fixedly connected to an outer wall of one side of the nut 13, a guide groove 301 is opened on one side of the extension rod 3 along the length direction, the guide block 12 is slidably connected to the guide groove 301, and the guide block 12 extends to the outside of the extension rod 3; a shielding mechanism is provided on the inner side of the guide groove 301; the end of the guide block 12 away from the nut 13 is fixedly connected to the connecting rod 5, and the bottom end of the connecting rod 5 is fixedly connected to an outer wall of one side of the movable ring 6; the top of the screw rod 19 is fixedly connected to the knob 8, and the knob 8 is rotatably installed to the top of the handle 4.

[0036] The vertical driving mechanism can be used to drive the scraper mechanism to move along the length direction of the extension rod 3.

[0037] The shielding mechanism includes a fixed frame 15, a round roller 16 and a shielding belt 17; one end of the shielding belt 17 is fixedly connected to the guide block 12, and the shielding belt 17 covers the inner side of the guide groove 301 below the guide block 12, and the other end of the shielding belt 17 is wound around the cylindrical surface of the round roller 16; the fixed frame 15 is fixedly installed inside the conical connecting cover 2, the round roller 16 is rotatably connected to the fixed frame 15, and a spring 1601 is arranged between one end of the round roller 16 and the fixed frame 15, and the spring One end of 1601 is fixedly connected to the end cylindrical surface of the round roller 16, and the other end of the clockwork spring 1601 is fixedly connected to the fixed frame 15; one side of the end seat 18 is elastically connected to two pressure strips 21 through a spiral spring 20, and the two pressure strips 21 are respectively pressed to the two sides of the shielding belt 17, so that the shielding belt 17 is pressed and covered to the inner side of the guide groove 301, so as to prevent the protein peptide liquid from entering the inner cavity of the extension rod 3 through the guide groove 301 during sampling; an intermediate groove is formed between the two pressure strips 21 for the guide block 12 to pass through.

[0038] The shielding belt 17 in the shielding mechanism moves with the guide block 12. When the guide block 12 is in the highest position, the guide groove 301 can be blocked to prevent the material from entering the extension rod 3 during the sampling process. When the guide block 12 moves downward, the position of the end of the shielding belt 17 can be changed. The deformation elastic force of the spring 1601 can be used to drive the round roller 16 to rotate and reel in the shielding belt 17 to ensure that the shielding belt 17 is straightened. When the guide block 12 is reset upward, the shielding belt 17 on the round roller 16 can be pulled out, and the round roller 16 rotates to twist the spring 1601 to generate deformation and restore the elastic force.

[0039] The screw rod 19 and the knob 8 are provided with a circular hole 11 along the axial direction, and the circular hole 11 is loosely connected with a lifting rod 9, the bottom end of the lifting rod 9 is fixedly connected with a piston disk 14, and the piston disk 14 is connected to the inside of the suction barrel 1; the top end of the lifting rod 9 passes through the circular hole 11, and the top end of the lifting rod 9 is fixedly connected with a lifting handle 10, and the lifting handle 10 is located above the knob 8, and the bottom end of the suction barrel 1 is connected with a suction port 101; the above structure can enable the suction barrel 1 to perform suction; and after suction and sampling, the lifting rod 9 is pushed to discharge the material from the suction port 101 through the piston disk 14.

[0040] Working principle: When the entire protein peptide detection sampling device is in use, the handle 4 is held in one hand, and the lower end of the whole, that is, the suction cylinder 1, is inserted into the cylinder containing the protein peptide liquid to move the suction port 101 to the depth position to be sampled; then, the lifting handle 10 is pulled up to make the lifting rod 9 slide along the length direction of the circular hole 11, and the lifting rod 9 drives the piston disc 14 to move upward in the suction cylinder 1 to suck the material, and the protein peptide material can be sucked into the suction cylinder 1 through the suction port 101 for sampling. When sampling, the amount sucked in the suction cylinder 1 can be judged by observing the length of the lifting rod 9 extending on the knob 8, wherein the top part of the lifting rod 9 can be set with a scale to assist in judgment;

[0041] In the above sampling process, the scraping mechanism is at the upper end of the extension rod 3, that is, close to the handle 4. Figure 1-2 As shown, the guide block 12 is close to the upper end of the guide groove 301, wherein the shielding belt 17 covers and shields the guide groove 301, as shown in FIG. Figure 7-8 As shown, when sampling, it is prevented that the protein peptide enters the inner cavity of the extension rod 3 through the guide groove 301;

[0042] The suction barrel 1 sucks the sample, and after sampling is completed, the whole is pulled out from the protein peptide and moved to the liquid surface; then the knob 8 is turned to provide drive for the vertical drive mechanism, so that the screw 19 rotates, and the screw 19 and the nut 13 are threaded, and the guide block 12 and the guide groove 301 are guided, so that the nut 13, the guide block 12, the connecting rod 5 and the scraping mechanism are moved together along the length direction of the extension rod 3 to move closer to the suction barrel 1; during the movement, the rubber scraper 701 is used to scrape the extension rod 3 around to scrape off the protein peptides adhered to the extension rod 3 during sampling, and after scraping, the protein peptides fall into the barrel; when the rubber scraper 701 contacts the bottom of the extension rod 3, the scraper mechanism continues to move downward, and the rubber scraper 701 contacts the conical connecting cover 2, such as Figure 1As shown, the outer diameter of the conical connection cover 2 gradually increases from top to bottom. At this time, when the scraper mechanism moves downward, it can provide gradually widening extrusion for the elastic petals 7 around it. Through the elasticity of the elastic petals 7, all the elastic petals 7 are opened outward without causing obstruction and affecting the continued downward movement of the scraper mechanism. The rubber scraper strip 701 can scrape the conical connection cover 2. Although after opening, the rubber scraper strip 701 cannot completely surround the surface of the conical connection cover 2 after the diameter is increased, the rubber scraper strip 701 can scrape the protein peptide at a part of the surface of the conical connection cover 2 and fall back to In the barrel; while the scraping mechanism is moving downward, the rubber scraping sleeve 601 moves to the suction barrel 1, and the material on the outer wall of the suction barrel 1 can be scraped off by the rubber scraping sleeve 601; after scraping, the scraping mechanism is reset upward by turning the knob 8 to complete the scraping. Through the above-mentioned scraping operation, the material attached to the extension rod 3, the suction barrel 1 and a part of the conical connecting cover 2 can be scraped off and fall into the barrel, thereby avoiding waste and reducing the labor intensity of subsequent cleaning of attached materials. Only the material on the conical connecting cover 2 needs to be cleaned, which provides convenience for the overall use;

[0043] During the scraping process, the guide block 12 moves downward, and one end of the shielding belt 17 moves with the guide block 12. With the elastic force of the spring spring 1601, the round roller 16 can be driven to rotate to reel in the shielding belt 17, and the shielding belt 17 can be kept taut all the time. During the process of the shielding belt 17 being reeled in by the round roller 16, the shielding belt 17 is pressed against the inner side of the guide groove 301 because the shielding belt 17 is pressed by the compressed coil spring 20 and the pressure plate. When the shielding belt 17 is reeled and moved, the lower end of the guide groove 301 is close to the shielding belt 17, and the material adhering to the shielding belt 17 can be scraped off, and the material on the shielding belt 17 can be automatically removed.

[0044] After scraping the material, when the guide block 12 moves upward, the guide block 12 drives one end of the shielding belt 17 upward for resetting; the shielding belt 17 can be pulled out from the round roller 16, and the round roller 16 is unwound and rotated, and the spring spring 1601 can be twisted to restore the elastic force of the spring spring 1601.

[0045] When the entire extension rod 3 is inserted into the protein peptide for sampling, the scraper mechanism is located at the highest position, that is, close to the handle 4, and the scraper mechanism cannot be inserted into the protein peptide to avoid the scraper mechanism adhering to the protein peptide.
