[0023] like Figures 1-4 As shown, a portable lightweight electric scissors includes a handle 1 and a blade assembly 2, which are rotatably connected to the handle 1. The blade assembly 2 includes a fixed base 3 and a fixed blade 4 and a movable blade 5 disposed on the fixed base 3. A connecting shaft 6 is provided on the fixed base 3, which passes through the fixed blade 4 and is rotatably connected to the movable blade 5. The front end of the handle 1 is provided with an adapter 8 having a vertical rotation axis 7. A connecting rod 9, which is rotatably connected to the vertical rotation axis 7, is fixedly connected to the fixed base 3. The handle 1 has a recessed storage groove 10 on its front side, and the blade assembly 2 can rotate along the vertical rotation axis 7 into the storage groove 10. The handle 1 is also provided with a blade working position locking structure 11 and a movable blade driving assembly 12.

[0024] In this invention, when the cutter head assembly 2 is in the working position, the cutter head working position locking structure can lock the cutter head assembly. At this time, the movable cutter head can be driven by the movable cutter head drive assembly 12 to swing up and down slightly along the connecting shaft, thereby cooperating with the fixed cutter head to complete the cutting action. When carrying it out, the fixed seat inside the cutter head assembly can rotate along the vertical rotation axis so that the cutter head assembly enters the storage slot, which can reduce the risk of the cutter head assembly causing injury to the human body when going out. Therefore, it can be carried directly with you without having to be put in a toolbox, and it is highly portable.

[0025] Specifically, the movable cutter head drive assembly 12 includes a drive cavity 13 disposed inside the handle 1. The upper part of the drive cavity 13 is provided with a drive rod 15 supported by two springs 14. The outer end of the drive rod 15 extends out of the handle 1 and is provided with a rectangular slot 16. The inner end of the movable cutter head 5 is fixedly connected to a connector 17 that can form a snap-fit ​​with the rectangular slot 16. An electromagnet 18 is disposed between the two springs 14 and fixed to the bottom of the drive cavity 13. The drive rod 15 is made of a magnetic material that can form a magnetic attraction with the electromagnet 18. When the cutter head assembly 2 is in the working position, the connector at the inner end of the movable cutter head 5 can be inserted into the rectangular slot at the outer end of the drive rod. When the electromagnet is energized, it can attract the drive rod to move downward, thereby driving the outer end of the movable cutter head to move away from the fixed cutter head. After the electromagnet is de-energized, the spring can push the drive rod to move upward, thereby driving the outer end of the movable cutter head to move closer to the fixed cutter head. Through the cooperation of the electromagnet and the spring, a small reciprocating motion of the movable cutter head can be realized, so that the movable cutter head and the fixed cutter head can complete the cutting action.

[0026] Specifically, the handle 1 also contains a battery 19 that is electrically connected to the electromagnet 18.

The micro switch is connected to the power line connecting the electromagnet 18 and the battery 19. Pressing the reed-type button can activate the micro switch to energize the electromagnet and generate magnetic force. Releasing the press of the reed-type button will deactivate the electromagnet and the electromagnetic force will disappear.

[0028] Specifically, the cutter head working position locking structure 11 includes a locking rod 21 that can be horizontally inserted into a locking groove inside the fixed cutter head 4. A sliding groove 22 is provided on the back of the handle 1, and a pull rod 23, whose inner end is fixed to the locking rod 21, is slidably connected within the sliding groove 22. The outer end of the pull rod 23 protrudes outward from the sliding groove 22. When the cutter head assembly 2 is in the working position, moving the locking rod via the pull rod allows the locking rod to be inserted into the locking groove on the fixed cutter head. The locking rod can lock the fixed cutter head, preventing the cutter head assembly from rotating along the vertical rotation axis.

[0029] Preferably, the storage slot 10 is further provided with a blade storage position limiting structure 24, which includes an elastic band 25 fixed in the storage slot 10. After the blade assembly is folded into the storage slot, the elastic band can restrict the blade assembly in the storage slot.

[0030] Specifically, the magnetic material used to make the drive rod 15 is steel.
