Description

Technical Field

[0001] The utility model relates to the technical field of drug development, in particular to a pair of removal forceps. Background Art

[0002] The active ingredients used in some drugs are metabolites of bacterial species. In order to control the growth environment of the bacterial species and improve the yield of related products, the bacterial species need to be cultured. At present, when culturing, the culture solution is placed in a culture dish, and then a glass slide is placed in the culture dish, and then the bacteria are cultured. After the culture is completed, due to the large suction force generated between the glass slide and the culture dish, it is inconvenient to remove the glass slide. The conventional clamping tools such as tweezers provide limited clamping force, so the glass slide and tweezers are separated from each other when taking out. Utility Model Content

[0003] The utility model provides a taking-out pliers to solve the above-mentioned deficiencies in the prior art, solve the problem that the carrier sheet is difficult to take out, and has strong practicability.

[0005] A kind of removal forceps includes a concave frame, a concave rod is passed through the horizontal section of the concave frame, a concave piece is provided on the lower wall of the horizontal section of the concave frame, a concave spring piece is installed at the lower end of the concave piece, a pair of convex seats are symmetrically installed on the lower wall of the horizontal section of the concave frame, a clamp is hinged at the lower end of the clamp, the concave rod is passed through the concave spring piece, and both sides of the concave spring piece act on the inner wall of the clamp, a movable hole is opened on the clamp, a movable cross bar is provided at the lower end of the concave rod, and rollers are rotatably provided at both ends of the movable cross bar, and the rollers act on the outer wall of the clamp. By moving the concave rod downward, the rollers can act on the clamp, and then the clamp is rotated inward, and then the slide is stably clamped by the clamp, so as to facilitate the removal of the slide, and when the concave rod is pressed downward, the concave frame plays a supporting role to prevent the concave rod from causing damage to the culture dish when it moves downward. The concave spring piece facilitates the recovery movement of the clamp.

[0006] Furthermore, a placing platform is provided at the lower end of the vertical section of the concave frame, and the placing platform improves stability and avoids problems such as tilting of the concave frame.

[0007] Furthermore, the clamping plate has a V-shaped structure, which can achieve the clamping operation of the slide when rotating at a smaller angle.

[0008] Furthermore, the lower end of the splint is in a wedge-shaped structure, which facilitates inserting the splint into the culture medium.

[0009] Furthermore, an upper convex plate is provided on the upper wall of the horizontal section of the concave frame, a concave rotating part is hinged on the upper end of the upper convex plate, a handle is provided on the outer end of the concave rotating part, and a pressure wheel is rotatably provided inside the concave rotating part. Through the concave rotating part, the concave rod can be conveniently limited by the pressure wheel thereon, thereby ensuring that the splint provides sufficient clamping force during transfer.

[0010] The advantages of the above technical solution are:

[0011] The utility model facilitates the operations of clamping and taking out the slide glass. BRIEF DESCRIPTION OF THE DRAWINGS
