The top cover 2 and the receiving barrel 1 are detachable structures and can be reused after disinfection, reducing the use cost.

[0047] As Figures 2 to 4 shown, in a specific example provided by this application, the connecting member 4 includes a pillar 41 installed on the top cover 2, and an outer flange 42 is provided at the outer peripheral top of the pillar 41; the clamping member 3 is rotatably sleeved on the pillar 41, and the clamping member 3 is located between the outer flange 42 and the top cover 2. In this embodiment, the clamping member 3 can rotate on the pillar 41, and the outer flange 42 can prevent the clamping member 3 from slipping off the pillar 41, ensuring the stable operation of the clamping member 3 and thus ensuring the safety of needle separation.

[0048] In a specific example provided by this application, an external thread is provided on the outer periphery of the lower half of the pillar 41; the top cover 2 is provided with a connection hole, and an internal thread for cooperating with the external thread on the pillar 41 is provided in the connection hole. In this embodiment, the pillar 41 is detachably connected to the top cover 2 by threads, which is convenient for later replacement and maintenance.

[0049] As Figures 1 to 3 shown, in a specific example provided by this application, a gasket 32 is provided on the pillar 41 between the clamping member 3 and the top cover 2. In this embodiment, the gasket 32 between the clamping member 3 and the top cover 2 can reduce the wear between the clamping member 3 and the top plate, and improve the service life of the clamping member 3.

[0050] As Figures 1 to 3As shown, in a specific example provided by the present application, the clamping member 3 includes a clamping plate 31; one end of the clamping plate 31 is rotatably sleeved on the support column 41, and at least one side of the two sides in the length direction of the clamping plate 31 is provided with a clamping arc surface 311. In this embodiment, the clamping arc surface 311 on the clamping plate 31 is used to increase the contact area between the clamping plate 31 and the needle, ensuring the stability of the clamping plate 31 for clamping the needle. In other embodiments, there is no clamping arc surface 311 on the clamping plate 31, and the side surface of the clamping plate 31 is used to squeeze and hold the needle to be separated. Therefore, the present application does not limit the specific structure of the clamping plate 31, and any specific structure that can cooperate with the top cover 2 surrounding the side surface of the placement hole 21 to complete the clamping and limiting of the needle to be tested is within the protection scope of the present application.

[0051] As Figures 1 to 3 shown, in a specific example provided by the present application, the clamping member 3 further includes a dial block 33; the dial block 33 is installed at one end of the clamping plate 31 away from the support column 41. In this embodiment, a dial block 33 is installed at one end of the clamping plate 31 away from the support column 41, and the dial block 33 and the clamping plate 31 are integrally formed structures, ensuring the connection strength between the dial block 33 and the clamping plate 31, and the dial block 33 facilitates the user to rotate the clamping plate 31.

In this embodiment, the first semi-circular hole 211 and the second semi-circular hole 212 are used to cooperate with the outer peripheral surface of the needle, ensuring the stable clamping of the needle after cooperating with the clamping plate 31.

[0053] Furthermore, as Figure 1 and Figure 3 shown, in a specific example provided by the present application, the aperture of the first semi-circular hole 211 is smaller than the aperture of the second semi-circular hole 212. This embodiment provides a specific shape of the placement hole 21. Among them, the sizes of the first semi-circular hole 211 and the second semi-circular hole 212 are different, which are used to adapt to needles of different specifications, improving the applicability of the needle separation device of the present application. In other embodiments, the aperture of the first semi-circular hole 211 is larger than the aperture of the second semi-circular hole 212, or the aperture of the first semi-circular hole 211 is the same as the aperture of the second semi-circular hole 212. Here, the present application does not make any restrictions, and it can be selected according to actual needs.

[0054] As Figure 2As shown, in a specific example provided by the present application, the accommodating barrel 1 and the top cover 2 are connected by threads. Specifically, the bottom of the top cover 2 has a stepped ring 22 that is close to the center of the top cover 2 and extends downward. An external connecting thread 23 is provided on the outer periphery of the stepped ring 22; the top of the accommodating barrel 1 has an internal connecting thread 11 that mates with the external connecting thread 23. Specifically, both the external connecting thread 23 and the internal connecting thread 11 are single-turn threads. In actual use, the single-turn threads of the external connecting thread 23 and the internal connecting thread 11 can limit the connection between the top cover 2 and the accommodating barrel 1. In other embodiments, the number of turns of the connecting thread 23 and the internal connecting thread 11 is not limited and can be set according to actual needs.

[0055] During actual use, the external connecting thread 23 of the stepped ring 22 mates with the internal connecting thread 11 at the top of the accommodating barrel 1, causing the top cover 2 to cover the top of the accommodating barrel 1. It is worth noting that this embodiment provides a specific structure for the detachable connection between the accommodating barrel 1 and the cover plate. In other embodiments, the top cover 2 is snapped onto the top of the accommodating barrel 1. Thus, the present application does not limit the specific structure of the detachable structure between the top cover 2 and the accommodating barrel 1, and can be selected and set according to actual needs.

[0056] The specific embodiments of the present invention have been described above. It should be understood that the present invention is not limited to the above specific embodiments, and those skilled in the art can make various changes or modifications within the scope of the claims, which do not affect the essence of the present invention. Without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other arbitrarily.
