The first knife handle and the second knife handle are rotationally connected through a pin shaft. One end of the first knife handle is fixed with a first connecting piece, and one end of the second knife handle is fixed with a second connecting piece. A housing is fixed on the first connecting piece. A strip-shaped through hole is opened on the housing. The second connecting piece is located in the strip-shaped through hole. An arc-shaped rack is fixed inside the housing. The output shaft of the motor is fixedly sleeved with a gear meshing with the arc-shaped rack. A sleeve is rotatably sleeved on the output shaft of the motor. The second connecting piece is fixed on the sleeve.

[0006] Preferably, the side of the first knife handle is provided with a first anti-slip pattern, and the side of the second knife handle is provided with a second anti-slip pattern.

[0007] Preferably, one end of the first knife handle is fixed with a first knife head, and one end of the second knife handle is fixed with a second knife head.

[0008] Preferably, an arc-shaped sliding rod is fixed inside the housing. A sliding sleeve is slidably sleeved on the arc-shaped sliding rod. The motor is installed on the sliding sleeve.

[0009] Preferably, the arc-shaped sliding rod and the pin shaft are coaxial, and the arc-shaped rack and the pin shaft are coaxial.

[0010] Compared with the prior art, the beneficial effects of the utility model are:

[0011] In the present utility model, the motor drives the gear to rotate. The gear can push the sliding sleeve on the motor to slide on the arc-shaped slide bar through meshing with the arc-shaped rack. Therefore, the second connecting piece can be driven to move through the sleeve, and the second connecting piece drives the second knife handle to rotate. Thus, the second knife handle and the first knife handle rotate about the pin shaft, so as to realize the electric shearing operation of the first knife head and the second knife head. Through the electric operation, the operation is more labor-saving and accurate, and the convenience of use is improved; the first anti-slip pattern and the second anti-slip pattern can improve the stability of holding the first knife handle and the second knife handle, and reduce the crosstalk and sliding.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0019] Referring to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5, A micromanipulation scissors structure, comprising a motor 15, a first knife handle 1 and a second knife handle 2. The first knife handle 1 and the second knife handle 2 are rotatably connected by a pin shaft 9. One end of the first knife handle 1 is fixed with a first connecting piece 5, and one end of the second knife handle 2 is fixed with a second connecting piece 6. A housing 7 is fixed on the first connecting piece 5. A strip-shaped through hole 14 is opened on the housing 7. The second connecting piece 6 is located in the strip-shaped through hole 14. An arc-shaped rack 12 is fixed inside the housing 7. The output shaft of the motor 15 is fixedly sleeved with a gear 17 that meshes with the arc-shaped rack 12. A sleeve 16 is rotatably sleeved on the output shaft of the motor 15. The second connecting piece 6 is fixed on the sleeve 16. The motor 15 drives the gear 17 to rotate. The gear 17 can push the sliding sleeve 13 on the motor 15 to slide on the arc-shaped slide bar 11 through meshing with the arc-shaped rack 12. Therefore, the second connecting piece 6 can be driven to move through the sleeve 16, and the second connecting piece 6 drives the second knife handle 2 to rotate. Thus, the second knife handle 2 and the first knife handle 1 rotate about the pin shaft 9, so as to realize the electric shearing operation of the first cutting head 10 and the second cutting head 8. Through the electric operation, the operation is more labor-saving and accurate, and the convenience of use is improved. First anti-slip lines 3 are arranged on the side of the first knife handle 1, and second anti-slip lines 4 are arranged on the side of the second knife handle 2. The first anti-slip lines 3 and the second anti-slip lines 4 can improve the holding stability of the first knife handle 1 and the second knife handle 2, and reduce crosstalk and sliding. One end of the first knife handle 1 is fixed with a first cutting head 10, and one end of the second knife handle 2 is fixed with a second cutting head 8. An arc-shaped slide bar 11 is fixed inside the housing 7. A sliding sleeve 13 is slidably sleeved on the arc-shaped slide bar 11. The motor 15 is installed on the sliding sleeve 13. The arc-shaped slide bar 11 is coaxial with the pin shaft 9, and the arc-shaped rack 12 is coaxial with the pin shaft 9.

[0020] Working principle: When in use, the motor 15 drives the gear 17 to rotate. The gear 17 can push the sliding sleeve 13 on the motor 15 to slide on the arc-shaped slide bar 11 through meshing with the arc-shaped rack 12. Therefore, the second connecting piece 6 can be driven to move through the sleeve 16, and the second connecting piece 6 drives the second knife handle 2 to rotate. Thus, the second knife handle 2 and the first knife handle 1 rotate about the pin shaft 9, so as to realize the electric shearing operation of the first cutting head 10 and the second cutting head 8. Through the electric operation, the operation is more labor-saving and accurate, and the convenience of use is improved; the first anti-slip lines 3 and the second anti-slip lines 4 can improve the holding stability of the first knife handle 1 and the second knife handle 2, and reduce crosstalk and sliding.
