[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-6 As shown, this utility model provides a technical solution:

[0025] A disposable live body sampling forceps includes a fixed shell 1. A control rod 2 is movably disposed inside the fixed shell 1. An adjustment mechanism is movably disposed on one side of the control rod 2. The adjustment mechanism includes a connecting rod 3, an adjustment rod 4, an auxiliary rod 5, and a clamping block 6. The connecting rod 3 is movably disposed at both ends of one side of the control rod 2. The other side of the connecting rod 3 is movably connected to the outside of the fixed shell 1. An adjustment rod 4 is movably disposed at the connection between the connecting rod 3 and the fixed shell 1. An auxiliary rod 5 is movably disposed on the outside of the fixed shell 1 near the connecting rod 3. A clamping block 6 is movably disposed on the side of the adjustment rod 4 away from the connecting rod 3. One side of the clamping block 6 is movably connected to the other end of the auxiliary rod 5.

[0026] A fixed post 7 is fixedly installed on one side of the outer shell 1. The fixed post 7 is movably connected to the control rod 2. An elastic locking mechanism is fixedly installed on both sides of the outer shell 7. The elastic locking mechanism includes a fixed block 8, a linear spring 9, a telescopic rod 10 and a locking block 11. The fixed blocks 8 are fixedly installed on both sides of the outer shell 7. A linear spring 9 is fixedly installed on the side of the fixed block 8 away from the fixed post 7. A telescopic rod 10 is fixedly installed inside the linear spring 9. A locking block 11 is fixedly installed on the side of the telescopic rod 10 away from the fixed block 8. One end of the locking block 11 is fixedly connected to the linear spring 9.

[0027] In this embodiment, preferably, an anti-slip pad 12 is fixedly provided on the inner side of the clamping block 6. The anti-slip pad is designed to increase the friction between the clamping block and the living body to achieve stable sampling.

[0028] In this embodiment, preferably, a handle 13 is fixedly provided on the side of the fixed column 7 away from the fixed shell 1, and a pressing handle 14 is fixedly provided on the side of the control rod 2 away from the fixed shell 1. Through the cooperation between the handle and the pressing handle, the staff can complete the sampling of the live body by simply pushing and pulling.

[0029] In this embodiment, preferably, a protective shell 15 is movably provided on the outside of the fixing column 7. The setting of the protective shell effectively protects the fixing shell after the disposable sampling forceps are used, avoiding direct contact with the external environment and causing unnecessary environmental pollution.

[0030] In this embodiment, preferably, a plurality of engaging grooves 16 are provided on both sides of the interior of the protective shell 15. The engaging grooves 16 are movably connected to the locking block 11. Through the movable connection between the locking block and the corresponding engaging groove, the protective shell can be moved and fixed, and the fixed shell can be effectively protected.

[0031] In this embodiment, preferably, the protective shell 15 has a placement groove 17 inside, and a connection hole 18 is provided on the outside of the protective shell 15 near the handle 13. The connection hole 18 is movably connected to the fixing post 7. The placement groove is designed to completely enclose the fixing shell inside the protective shell, preventing it from directly contacting the external environment.

[0032] In this embodiment, a disposable live sampling forceps is used to perform live sampling. The palm rests against the handle 13, and the fingers are inserted into the sides of the pressing handle 14 to squeeze. The control rod 2 moves to one side inside the fixed post 7, and the connecting rods 3 at both ends extend outwards, thereby causing the adjusting rod 4 to retract inwards. With the support of the auxiliary rod 5, the clamping block 6 shifts to clamp the live sample. After removing the sample, the pressing handle 14 is pulled in the opposite direction to unfold the clamping block 6 to place the live sample. After processing, the sampling forceps can be dragged by the operator for protection. The shell 15, through the elastic deformation of the linear springs 9 at both ends of the fixing column 7, allows the locking block 11 to be movably connected to the locking groove 16, which can completely wrap the fixing shell 1 and finally discard it. The device has a layered adjustment mechanism, and the staff can achieve the gripping of the live body by simply pushing and pulling. The entire gripping process is more stable and the gripped object is not easy to fall off. The movable protective shell 15 can effectively protect the sampling forceps itself after the disposable sampling forceps are used and discarded, avoiding direct contact with the external environment and causing unnecessary environmental pollution.
