Detailed Description

The following detailed description of the preferred embodiments of the present invention will be provided in conjunction with the accompanying drawings, so as to enable those skilled in the art to more easily understand the advantages and features of the present invention, and thereby define the scope of the invention more clearly and clearly.

The first embodiment is as follows:

the utility model discloses a laboratory is with sealer is used for sealing the processing in the bottleneck of reagent bottle and sealing it with the sealing film cladding. Referring to fig. 1, the sealing machine of the present embodiment includes a supporting plate 1, a fixing shaft 2 for sleeving a sealing film is disposed on the supporting plate 1, a blade fixing rod 3 is disposed on the supporting plate 1 in parallel with the fixing shaft 2, a cutting blade 4 is disposed on the blade fixing rod 3 along a length direction thereof, and the cutting blade 4 is zigzag.

A plurality of clamping grooves 31 recessed toward the axial center line thereof are formed in the blade fixing rod 3, and the clamping grooves 31 are sequentially arranged along the length direction of the blade fixing rod 3.

The utility model discloses a laboratory is with sealer still includes that at least one can block into the joint ring 5 that is "C" shape in the joint groove 31 (see that fig. 2 shows), is provided with cutting blade 51 on joint ring 5, the utility model discloses a joint ring 5 adopts and prepares with elastic material (like silica gel or rubber) and comes, therefore, can ensure that joint ring 5 and blade dead lever 3 are connected stably, can adjust the position of joint ring 5 as required again. The cutting blade 51 is disposed on the outer surface of the snap ring 5 and extends in a direction away from the center of the snap ring 5. Therefore, the cutting blade 51 can push up the sealing film, and the sealing film can be cut easily.

The end of the fixing shaft 2 far away from the supporting plate 1 is detachably provided with a limit cap 6. Therefore, when the rolled sealing film is sleeved on the fixed shaft 2, the position of the sealing device can be moved as required, and the sealing film can not fall off even if the sealing film is positioned below the supporting plate 1.
