Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Example 1
Referring to fig. 1-3, in the embodiment of the present invention, a pair of scissors for plant tissue culture includes an arc-shaped blade 1 and a pin 2, wherein the arc-shaped blade 1 is fixedly connected with a knife bar 4, one end of the knife bar 4 away from the arc-shaped blade 1 is fixedly connected with a holding ring 5, the two arc-shaped blades 1 are rotatably connected through the pin 2, and a springback assembly is further disposed between the two knife bars 4;
the upper end of the arc-shaped blade 1 is fixedly connected with two sliding seats 7, limiting rods 9 are slidably connected in the two sliding seats 7, limiting caps 6 are arranged at the ends, far away from the cutting edge of the arc-shaped blade 1, of the limiting rods 9, a toothed plate 10 is fixedly connected between the ends, far away from the limiting caps 6, of the two limiting rods 9, and first springs 8 penetrate through the positions, located between the toothed plate 10 and the sliding seats 7, of the limiting rods 9; one end of the arc-shaped blade 1, which is far away from the pin 2, is in a pointed cone shape; the shape of the holding ring 5 is semicircular; the limiting cap 6 is in threaded connection with the limiting rod 9.
