Referring to fig. 3 and 4, in some embodiments of the present invention, the connection means is an internal threaded rod 510 and a threaded rod 520, one end of the internal threaded rod 510 is provided with a first end cap 511, the other end is provided with a threaded hole 512, one end of the threaded rod 520 is provided with a second end cap 521, the internal threaded rod 510 passes through the through holes 110 of the left clip 100 and the right clip 200, the threaded rod 520 is connected in the threaded hole 512, and the first end cap 511 and the second end cap 521 are respectively tightly attached to the left clip 100 and the right clip 200.

The inner screw 510 passes through the through holes 110 of the left and

right clips

100 and 200 and is screwed into the screw hole 512 using the screw 520, and the first and

second end caps

511 and 521 fix the left and

right clips

100 and 200 in the axial direction of the through holes 110 while the left and

right clips

100 and 200 are able to rotate around the shaft. Since the inner threaded rod 510 and the threaded rod 520 can be disassembled, it can be easily replaced and repaired in case of damage to the left or

right clip

100 or 200.

In some embodiments of the present invention, the connecting means is a rivet movably riveted in the through holes 110 of the left and

right jaws

100 and 200.

The rivet is adopted for movable riveting, when the cell climbing film clamp is used for a plurality of times for a long time, the left clamping piece 100 and the right clamping piece 200 can not be loosened, and the connection is simple and reliable.

In some embodiments of the present invention, the included angle formed between the left clip 100 and the right clip 200 is 10 ° to 40 °.

When the included angle formed between the left clamping piece 100 and the right clamping piece 200 is larger than 40 degrees, the distance between the front ends of the left clamping piece 100 and the right clamping piece 200 is far, a long picking piece 400 needs to be arranged, and the operation of supporting cell climbing is inconvenient; when the included angle formed between the left clamping piece 100 and the right clamping piece 200 is smaller than 10 degrees, the distance between the front ends of the left clamping piece 100 and the right clamping piece 200 is close, and the forceps head 300 is inconvenient to move away after the picking-up piece 400 contacts the cell climbing piece.

In some embodiments of the present invention, the left clip 100 and the right clip 200 are made of an elastic material.

Adopt left clamping piece 100 and right clamping piece 200 that elastic material made, conveniently hold between the fingers and hold the operation, after the cell climbing piece is colluded up to tweezers head 300, reuse pick up piece 400 contact cell climbing piece, can hold between the fingers at this moment and hold and be close to right clamping piece 200 with left clamping piece 100 incurvation, make tweezers head 300 not contact with cell climbing piece, then move aside left clamping piece 100, cell climbing piece can stably contact the bearing on picking up piece 400.

In some embodiments of the utility model, the forceps head 300 is a triangular structure, where two corners are connected to the left clip 100, the remaining one corner faces outward, and the corner is provided with a cutting edge.

When the cell climbing sheet is arranged in the culture dish, the gap between the cell climbing sheet and the bottom of the culture dish is smaller, the forceps head 300 is arranged to be of a triangular structure, and the outward angle is provided with a blade surface, so that the forceps head 300 is easier to stretch into the bottom of the cell climbing sheet.

In some embodiments of the present invention, the pick-up sheet 400 has a thickness of less than 0.5 mm. When the thickness of the picking-up piece 400 is larger than 0.5mm, the picking-up piece is easy to interfere with the bottom of the culture dish and is inconvenient to extend into the bottom of the cell climbing piece.
