[0014] Figure 4 This is a schematic diagram of the decomposition structure of Example 2 of the present invention. DETAILED DESCRIPTION

[0015] Example 1: Figure 1-Figure 3 As shown, an electric scissors with anti-slip teeth includes a fixed plate 1, a swing blade 2, an output tooth 3 and a base 4 for installing various components. The swing blade 2 includes a fixedly assembled cutter head 5 and a tail piece 6. The cutter head 5 and the tail piece 6 form the swing blade 2, which is conducive to replacing parts and reducing the cost of use. A connecting shaft 7 that runs through the cutter head 5, the tail piece 6 and the base 4 is provided. An auxiliary fixed connection point is provided between the cutter head 5 and the tail piece 6. The connection point can be formed by the matching of a convex column and a hole, but this is not the only limitation. There are two assembly points between the cutter head 5 and the tail, namely the connecting shaft 7 and the connecting point, so that the relatively fixed assembly relationship between the two can be confirmed. One end of the connecting shaft 7 is provided with a stopper 8 that limits the swing blade 2 from disengaging. The stopper 8 limits the disengagement of various components and strengthens the tightness of the structure. The tail piece 6 has a connecting tooth part 9 that meshes and links with the output tooth 3. The connecting tooth part 9 is used for meshing transmission, and no further explanation and limitation are made here. The base 4 is also provided with a connection block 10, a pressure plate 11 and a movable part 12. The two ends of the pressure plate 11 are respectively fixedly assembled at the connection shaft 7 and the connection block 10. The movable part 12 is limitedly assembled between the two ends of the pressure plate 11, and the movable part 12 abuts and slides against the tail piece 6. It should be pointed out that the pressure plate 11 plays a role of connection and pressing, and the movable part 12 cooperates to make up for the empty space of the pressing, that is, the part between the ends of the pressure plate 11. At the same time, the movable part 12 is relatively movable, which greatly weakens its friction resistance to the tail piece 6 and hardly affects normal use.

[0016] The movable member 12 is a ball-shaped structure, the pressure plate 11 is provided with a mounting groove 13 for limiting the movable member 12, the tail piece 6 is provided with an arc-shaped slide groove 14 for the movable member 12 to move, and the movable member 12 is arranged between the mounting groove 13 and the arc-shaped slide groove 14 for clamping and limiting. The ball-shaped structure is simple, easy to process and assemble, and the arc-shaped slide groove 14 with an arc-shaped track is synchronously provided to reduce the slide groove resistance as much as possible, and also prevent the movable member 12 from being disengaged from the displacement.

[0017] The pressing plate 11 is a T-shaped structure, and the two colinear ends of the pressing plate 11 are threadedly connected and fixed to the connecting block 10. Compared with the general shape, the T-shaped structure reduces the cost, and the multiple connection points are conducive to improving the connection tightness and compensating for the looseness of the threaded connection after long-term use.

[0018] The stopper 8 is flange-shaped, and the stopper 8 and the pressure plate 11 are axially stoppered and limited, and a plane bearing 15 is also provided between the pressure plate 11 and the tail piece 6. The friction loss of the parts is reduced, the smoothness is improved, and the stoppering and limiting are also effectively performed.

[0019] The mounting groove 13 is hemispherical in shape, and the outer diameter of the mounting groove 13 is larger than the diameter of the movable part 12. The mounting groove 13 passes through the pressure plate 11 to form an opening 16 for filling lubricating oil, and the diameter of the opening 16 is smaller than the diameter of the movable part 12. The mounting groove 13 can be processed without too much thickness of the pressure plate 11, which is convenient for meeting the design and use requirements. The opening 16 can be filled with lubricating oil to improve smoothness, and can also be ventilated to avoid interference with the movable part 12.

[0020] Embodiment 2: Different from embodiment 1, as Figure 4 As shown, the pressing plate 11 is provided with a slot 17 penetrating the pressing plate 11, and the inner wall of the slot 17 is provided with a transverse axis 18 for the movable member 12 to be movably assembled. The movable member 12 is a roller-shaped structure. In this embodiment, auxiliary structures such as grooves do not need to be processed, and the movable assembled roller can be directly used.

[0021] In the description of the present invention, it should be noted that the terms "center", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention. At the same time, the basic principles, main features and advantages of the present invention are shown and described above, which should be understood by technicians in this industry.
