Description

Tweezers

for vasosuyvayuschie apparatus known.

In the proposed pipette, in contrast to the known, one of its sponges is made with a segmental groove, and the second is provided with a corresponding protrusion. Such an embodiment of the tweezers creates comfort when charging the sleeves with brackets and allows the backs of the brackets to give the necessary curvature.

FIG. 1 shows the proposed PNPT when bending brackets (a - the sponges of tweezers are divorced, b - compressed); in fig. 2 - tweezers when charging the sleeve with a staple (Q - tweezers' jaws are divorced, b - squeezed).

The tweezers consist of two branches with pa6o4HNrii sponges / and 2, one of which (/) is made with a segment groove 3. The diameter of the groove is equal to the diameter of the vase of the sleeve of the vessel. The other sponge 2 has a protrusion 4 corresponding to the groove 3. When the jHiH sponges are closed, the protrusion 4 of the sponge 2 enters the groove 3 of the sponge /. Since the width of the groove 3 and the protrusion 4 is very small than the height of the bracket 5, its spike will protrude from the ini- cet when charging the bushing of the vessel.

The tweezers are operated in the following way.

The bracket 5 places the notch 3 of the spnpcon inside the groove (see Fig. 1. o) on both branches with a force of compressed;) (see Fig. 1, 6i. At the same time, the radius is bent according to the direction of the sleeve. Then, opening, insert the bracket 5 into the groove 3 so that its brackets, and it protrudes 1h (see Fig. 2, o). P 1 nce, insert the bracket 5 into the groove of the vascular sleeve of the device;

brackets (see. 2. b).
