[0049] A rack 612 is fixed to the bottom of the fixed frame 10, and a gear 613 meshing with the rack 612 is fixed to the middle of the transmission rod. The gear 613 is fixed in the middle of the transmission. When the rack 612 is driven to move by the fixed frame 10, the rack 612 drives the gear 613 meshing with it to rotate, and the gear 613 drives the transmission plate 614 to rotate through the transmission rod.

A rectangular groove adapted to the insert block is opened on the crossbeam, and a slide rod is fixed in the rectangular groove. A lifting groove adapted to the slide rod is provided on the insert block.

[0050] By adopting the above technical solution:

[0051] When in use, when the output end of the electric hydraulic rod 4 pushes the fixing frame 10 to move downward, the fixing frame 10 drives the rack 612 to move downward, and the rack 612 drives the gear 613 meshing therewith to move downward. When the gear 613 contacts the transmission plate 614, the fixing frame 10 drives the slide bar to move downward, so that the slide bar moves to the bottom of the installation groove and continues to push the rack 612 to move downward, so that the gear 613 drives the transmission rod to rotate, and the transmission rod drives the transmission plate 614 to rotate, so that the transmission plate 614 cooperates with the plurality of first convex teeth and the plurality of second convex teeth, so that the transmission plate 614 drives the force-bearing plate 605 to rotate, so that the force-bearing plate 605 The force disk 605 drives the sealing disk 602 to rotate, so that the sealing disk 602 drives the annular groove to move, and drives the plurality of second limiting posts 610 to move through the annular groove, so that the plurality of second limiting posts 610 drive the plurality of moving blocks 604 to move, and at the same time, the plurality of first limiting posts 609 cooperate with the plurality of slide grooves, so that the plurality of moving blocks 604 rotate on the sealing disk 602, so that the plurality of moving blocks 604 drive the plurality of cleaning blocks 608 to rotate, so that the spacing between the plurality of cleaning blocks 608 becomes larger, so that the plurality of cleaning blocks 608 are separated from the sampling needle of the sampler 5, so that the sampling needle of the sampler 5 can quickly pass through the sampling hole for sampling;

[0052] When sampling is completed, the fixing frame 10 drives the sampler 5 to move upward, and at the same time, the fixing frame 10 drives the sliding rod to move upward, so that the sliding rod moves to the top of the mounting groove and then drives the rack 612 to move upward, so that the rack 612 drives the moving block 604 to rotate through the cooperation of the gear 613 and the transmission disk 614, so that the multiple moving blocks 604 drive the multiple cleaning blocks 608 to move, and the sampling needle of the sampler 5 after sampling is wiped by the multiple cleaning blocks 608 to prevent the sampling needle of the sampler 5 from moving to the top of the sampler 5 and residual protamine sulfate injection liquid.

[0053] Secondly, refer to Figure 6 and Figure 7 As shown, a protrusion is fixed at one end of the cleaning block 608, and a groove matching the protrusion is provided at the end of the moving block 604 away from the first limiting column 609. The cleaning block 608 is installed on the moving block 604 through the protrusion, and a cleaning cloth can be provided on the outer wall of the cleaning block 608, and the sampling needle of the sampler 5 is cleaned by the cleaning cloth.

[0054] By adopting the above technical solution:

[0055] When in use, push multiple cleaning blocks 608 to move, so that the cleaning blocks 608 drive the protrusions to move, and after the protrusions move to the outside of the grooves, separate the cleaning blocks 608 from the moving blocks 604, and disassemble the cleaning blocks 608, thereby facilitating people to quickly replace the cleaning blocks 608, which is convenient and quick.

[0056] Again, reference Figure 1 , Figure 8 and Fig. 9 As shown, the clamping device 7 includes a bidirectional threaded rod 702 and a baffle rod 703 rotatably mounted at the bottom of the fixed frame 10, and two movable clamping blocks 701 are symmetrically arranged on the bidirectional threaded rod 702 and the baffle rod 703. A triangular slot is arranged on the opposite side of the two clamping blocks 701, and an adjusting button 705 is fixed to the middle of the bidirectional threaded rod 702. The two clamping blocks 701 are respectively provided with threaded holes matched with the bidirectional threaded rod 702 and limiting holes matched with the baffle rod 703. The bidirectional threaded rod 702 is rotated by rotating the adjusting button 705, so that the bidirectional threaded rod 702 is matched with the threaded hole. At the same time, the clamping blocks 701 are limited by the baffle rod 703, so that the spacing between the clamping blocks 701 becomes larger or smaller, and the sampler 5 is clamped and fixed.

[0057] Two liftable lifting rods 704 are arranged at the ends of the two clamping blocks 701 away from the card slots, and extension rods are arranged on the opposite sides of the two lift rods 704. The two extension rods are in contact with the bottom of the sampler 5, and two baffles are arranged on the top of the lift rods 704. Mounting holes for facilitating the lifting of the lift rods 704 are arranged on the clamping block 701. The diameters of the two baffles are smaller than the mounting holes, and the lift rods 704 are limited by the two baffles to prevent the lift rods 704 from separating from the clamping block 701. The lifting and lowering of the lift rods 704 drives the two extension rods to be lifted and lowered, thereby adjusting the length of the sampler 5 after passing through the card slot, thereby facilitating the adjustment of the depth of the sampling needle of the sampler 5 entering the sample storage tube 2.

[0058] By adopting the above technical solution:

[0059] When in use, rotate the adjusting knob 705, and the adjusting knob 705 drives the bidirectional threaded rod 702 to rotate, so that the bidirectional threaded rod 702 cooperates with the threaded hole to drive the clamping block 701 to move, and the clamping block 701 moves along the outer wall of the blocking rod 703, and adjusts the distance between the two clamping blocks 701 to make the distance between the clamping blocks 701 larger or smaller, so as to clamp samplers 5 of different sizes, thereby further improving the convenience of the device.

[0060] Finally, reference Figure 8 , Fig. 9 and Fig.11As shown, two retractable locking rods 706 are provided on the opposite sides of the two clamping blocks 701, and two springs 707 are fixed between the two locking rods 706 and the two clamping blocks 701. A plurality of locking holes compatible with the locking rods 706 are provided on the opposite sides of the two lifting rods 704. The locking rods 706 penetrate the clamping blocks 701 and are inserted into the locking holes. After the locking rods 706 are pulled to the outside of the locking holes, the lifting rods 704 are pushed to move, so that the lifting rods 704 drive the extension rods to move. Through the cooperation of the locking rods 706 and the locking holes, people can quickly adjust the distance between the extension rods and the clamping blocks 701.

[0061] By adopting the above technical solution:

[0062] When in use, pull the locking rod 706 to move the locking rod 706 to the outside of the locking slot, push the lifting rod 704 downward to move the lifting rod 704 downward, and the lifting rod 704 drives the extension rod to move downward, adjust the distance between the extension rod and the clamping block 701, and adjust the length of the sampler 5 after passing through the slot, thereby adjusting the length of the sampling needle of the sampler 5 passing through the sampling hole, so as to facilitate people to sample the protamine sulfate injection solution at different depths inside the sample storage tube 2.

[0063] In addition, according to Figure 1-Figure 11 As shown, the present invention also provides a method for using a protamine sulfate injection detection sampling device, comprising the following steps:

[0065] S2. After the sampler 5 is installed inside the clamping device 7, the fixed frame 10 is driven to move through the output end of the electric hydraulic rod 4, so that the fixed frame 10 drives the sampler 5 to move downward through the clamping device 7, and at the same time, the fixed frame 10 drives the rack 612 to move downward, so that the rack 612 cooperates with the gear 613 to drive the transmission mechanism to rotate, so that the transmission mechanism drives the multiple moving blocks 604 to move, and the moving blocks 604 drive the cleaning block 608 to move, so that the sampling needle of the sampler 5 enters the interior of the sample storage tube 2 to sample the protamine sulfate injection solution;
