[0027] A movable blade 4 is provided on the top surface of the fixed blade 2 away from the mounting bracket 3. A snap-fit ​​bracket 5 is provided on the top surface of the movable blade 4. Mounting holes 51 are provided on both sides of the snap-fit ​​bracket 5. The first twist wall 34 snaps into the mounting holes 51. After the first twist wall 34 is away from the mounting holes 51, the snap-fit ​​bracket 5 and the movable blade 4 are removed from the fixed blade 2. Then the snap-fit ​​bracket 5 and the movable blade 4 are separated. After replacing the new movable blade 4, the installation can be carried out in the reverse order. Example

[0028] Please see Figure 1-3This is the second embodiment of the present invention. This embodiment is based on the previous embodiment. A groove 21 is provided on one side of the top surface of the fixed blade 2. The groove 21 can make the moving blade 4 swing left and right in a specified direction.

[0029] Two torsion springs 33 are fixedly connected to one end of each other with a second torsion wall 35. The second torsion wall 35 is snapped into the middle of the mounting bracket 3. A snap-fit ​​strip 36 is fixedly connected to one side of the mounting bracket 3. The snap-fit ​​strip 36 is snapped into the mounting part of the electric scissor body 1. The snap-fit ​​strip 36 can snap the mounting bracket 3 into the electric scissor body 1. The setting of the second torsion wall 35 installs the torsion springs 33 onto the mounting bracket 3, so that they are in a pre-torsion state.

[0030] The moving blade 4 has round holes 41 through both sides, a square hole 42 through the middle of the moving blade 4, and a snap-fit ​​groove 43 on one side of the moving blade 4; the round holes 41, the square hole 42 and the snap-fit ​​groove 43 on the moving blade 4 facilitate its installation with the snap-fit ​​bracket 5.

When it is necessary to replace the moving blade 4, remove the fixed blade 2, mounting bracket 3, moving blade 4, and snap-fit ​​bracket 5 from the electric scissors body 1. Then rotate the rotating rod 31. The rotation of the rotating rod 31 drives the connecting plate 32 to rotate. The end of the connecting plate 32 contacts the bottom of the first twisted wall 34 and lifts the first twisted wall 34. The first twisted wall 34 moves out of the mounting hole 51. At this time, the snap-fit ​​bracket 5 and the moving blade 4 can be removed normally. After removal, remove the snap-fit ​​bracket 5 from the moving blade 4, find the new moving blade 4, align the round hole 41 of the new moving blade 4 with the cylindrical rod 55, the square hole 42 with the slider 52, and the snap-fit ​​groove 43 with the snap-fit ​​plate 53. Install the new moving blade 4 and the snap-fit ​​bracket 5. The mounting bracket 5 is placed on the top surface of the fixed blade 2, the slider 52 is inserted into the slide groove 21, the rotating rod 31 is rotated, the rotating rod 31 rotates and drives the connecting plate 32 to lift the first twisted wall 34, the user holds the first twisted wall 34 and installs the end of the first twisted wall 34 into the mounting hole 51, thus completing the installation. Then the fixed blade 2, the mounting bracket 3 and the mounting bracket 5 are installed as a whole onto the electric scissor body 1. The threaded rod 6 can fix the mounting bracket 3 and the fixed blade 2. The connecting bracket 54 is connected to the motor shaft of the electric scissor body 1, and the mounting strip 36 is connected to the mounting point on the electric scissor body 1. In this utility model, the moving blade 4 is installed with the fixed blade 2 through a simple installation structure.
