A slot 4 matching the lower end of the sleeve 1 is located in the sleeve head 2 above the partition 3. A cutting groove 5 for accommodating the cut agar blocks is located in the sleeve head 2 below the partition 3. A toothed cutting blade 6 is provided at the lower end of the sleeve head 2, with multiple cutting blades evenly spaced around the circumference of the sleeve head 2. In use, the clean sleeve head 2 is snapped onto the lower end of the sleeve 1, and the agar plate is punched and cut through the lower end of the sleeve head 2. The toothed cutting blade 6 allows part of the bottom of the cut agar to protrude. Since the agar has a certain degree of stickiness, the agar block inside the sleeve head 2 can be removed by adhering the bottom of the agar to the target location.

[0024] The upper end of the sleeve 1 is fixedly installed with a blocking head 7 through a bolt, the blocking head 7 is provided with a guide hole 8 penetrating along the axial direction of the sleeve 1, the guide hole 8 is slidably installed with a core rod 9, the lower end of the core rod 9 is fixedly installed with a plug head 10 for pushing the sleeve head 2 to fall off from the lower end of the sleeve 1 through a thread, the upper end of the core rod 9 is fixedly installed with a push head 11 through a thread, and the core rod 9 between the push head 11 and the blocking head 7 is sleeved with a spring 12. In the embodiment, the outer wall of the core rod 9 below the blocking head 7 is provided with an annular limiting part 13, when there is no external force, the spring 12 is stretched and pushes the core rod 9 to move upwards, and the limiting part 13 abuts against the lower end of the blocking head 7, at this time, the plug head 10 is retracted into the lower end of the sleeve 1 upwards. When the sleeve head 2 at the lower end of the sleeve 1 completes a punching and cutting, the push head 11 is pressed downwards against the elastic force of the spring 12, the push head 11 drives the plug head 10 to move downwards through the core rod 9, the plug head 10 extends out of the lower end of the sleeve 1 and pushes the sleeve head 2 to fall off from the lower end of the sleeve 1, then a new clean sleeve head 2 is reinstalled at the lower end of the sleeve 1, and then the next punching and cutting can be carried out.

[0025] In the embodiment, the upper end of the blocking head 7 is integrally formed with an annular handle 14 located outside the sleeve 1, so that the handle 14 is conveniently hooked by the index finger and the middle finger and the push head 11 is pressed downwards by the thumb.

[0026] In the embodiment, the lower end of the sleeve 1 is integrally formed with an annular protruding part 15 arranged around the circumferential direction, and the inner wall of the clamping groove 4 is provided with an annular groove 16 for clamping the protruding part 15, so as to improve the stability of the installation of the sleeve head 2.

[0027] In the embodiment, one side of the sleeve 1 is provided with an opening 28 arranged along the axial direction, so as to avoid a sanitary dead angle and facilitate disinfection.

[0028] In the embodiment, the sleeve head 2 is a disposable sleeve head, the sleeve head 2 can be made of plastic material, and the sleeve head 2 can be directly discarded after use. The sleeve 1, the blocking head 7, the core rod 9, the plug head 10, the push head 11 and the spring 12 are all made of high-temperature-resistant metal materials such as steel and copper, so as to be sterilized by burning after use.
