Further, the blade is a detachable scalpel blade.

Furthermore, the end part of the knife handle is provided with a knife handle head protrusion for mounting a scalpel blade.

Furthermore, the right knife handle is provided with a knife sleeve formed by a sliding groove.

Furthermore, the rear end of the handle of the right side connecting blade is fixed on the slide plate in the slide groove.

Further, the blade at the front end of the end part of the right knife handle can slide along the groove rail and retract into the knife sleeve.

Further, the depth of the knife pouch can fully accommodate the retracted blade.

Further, the right knife handle, the knife sleeve and the blade are connected into a whole.

Further, under the normal state, an angle of 10 degrees is formed between the two tool handles.

Furthermore, the single-side telescopic tweezer knife body is made of stainless steel.

Compared with the prior art, the utility model discloses have following advantage when cutting electrophoresis adhesive tape and other samples:

(1) The cutting of the gel is rapid, two cutters can be cut during each cutting, the cutting is convenient, and the efficiency of cutting gel and other samples is improved.

(2) Surely glue accurately, compare in traditional cutting gel piece cutter, the utility model discloses distance between two adjustable blades, accurate cutting is glued the piece, avoids repeated cutting.

(3) Convenient clamp is got and is glued the piece, the utility model discloses a back is accomplished in overall structure similar traditional tweezers, will glue the piece clamp with the blade and get and put into the centrifuging tube.

(4) When the use of cutting gel is reduced, the gel cutting efficiency is improved, the ultraviolet irradiation time is reduced, the base mutation probability is reduced, and the hands, eyes and the like of experimenters are prevented from being subjected to ultraviolet radiation for a long time.

(5) Removable blade, the utility model discloses a scalpel blade installation notch and the protruding phase-match of handle of a knife head, the same with the scalpel structure, can change the blade after the blade is impaired.

(6) The sword and the changeable of tweezers function, the utility model discloses in the right side blade can be followed the grooved rail and slided the withdrawal cutter cover, can use left side blade single-edged cutting, when both sides blade and when neat, can the twolip cutting, also can exert tweezers and press from both sides and get the function.

Drawings

The accompanying drawings, which form a part hereof, are included to provide a further understanding of the invention, and are incorporated in and constitute a part of this specification, illustrate embodiments of the invention and together with the description serve to explain the invention without undue limitation. In the drawings:

fig. 1 is a schematic structural diagram of the present invention.

In the figure: 1. a scalpel blade; 2. the blade mounting groove and the tool shank head are protruded; 3. a knife handle; 4. a cutter tail; 5. the knife handle and the sliding block are fixed; 6. the rear end of the right knife handle; 7. a slider; 8. a groove rail; 9. a sliding groove knife sleeve;

Detailed Description

It should be noted that, in the present invention, the embodiments and features of the embodiments may be combined with each other without conflict.

When cutting the gel block, the right blade can slide out of the knife sleeve 9, the two blades 1 are in a tweezers shape after being aligned, the two blades 1 are mutually closed by fingers, the distance between the blades is adjusted to be suitable for the width of the gel block to be cut, the blades are moved to cut, and the gel block to be cut is clamped and placed in the centrifugal tube after cutting. If only one-side blade is needed for cutting in the cutting process, the sliding block 7 can be pushed slightly to enable the right-side blade to slide along the groove rail 8 and be retracted into the cutter sleeve 9, so that flexible cutting is facilitated; and meanwhile, the knife handle is prevented from being scratched by the blades which are retracted and placed when the knife handle is held by a hand. The blade can be replaced by oneself after the blade is damaged in use.
