The metal connector 30 may be made of metal such as iron, copper or stainless steel. The movable knife 40 is a metal knife, and the part of the movable knife support 10 used for being connected with the movable knife 40 is a metal piece, so that the connection strength of the movable knife 40 and the metal connecting piece 30 can be improved, and the structural stability of the movable knife assembly is ensured. It will be appreciated that the volume of the plastic support 20 may be greater than the volume of the metal connector 30 to increase the specific gravity of the plastic support 20 in the movable blade support 10, thereby effectively reducing the processing cost of the movable blade support 10.

There are many ways to connect the movable blade 40 to the metal connector 30, such as adhesive, clamping, or screw connection.

Illustratively, as shown in fig. 2 and 3, fig. 3 is a cross-sectional exploded view of an embodiment of a movable blade assembly of the electric shearing apparatus of the present utility model. The metal connecting piece 30 is convexly provided with a connecting rib 31, the movable knife 40 is provided with a fixing groove 41, and the connecting rib 31 is fixedly matched with the fixing groove 41.

The movable blade 40 includes a base plate and blade teeth connected to the side of the base plate, and the fixing groove 41 is formed in the base plate. The fixing groove 41 may be square, circular, or other shapes, and the shape of the connecting rib 31 corresponds to the shape of the fixing groove 41. The connecting rib 31 is protruding on the top of the metal connecting piece 30, and may be formed integrally with the metal connecting piece 30, or may be connected and fixed by other means, and only the same material of the connecting rib 31 and the metal connecting piece 30 is required.

Specifically, the connecting rib 31 is welded and fixed to the groove wall of the fixing groove 41. It should be noted that, the connecting rib 31 is a metal structure in this embodiment to achieve the welding fixation with the movable blade 40. The connecting rib 31 is welded and fixed with the groove wall of the fixed groove 41, so that the connecting rib 31 can be prevented from being separated from the fixed groove 41, and the connection strength of the metal connecting piece 30 and the movable knife 40 can be further improved.

The number of the fixing grooves 41 may be one, or two or more, and the number and positions of the connection ribs 31 correspond to those of the fixing grooves 41.

As shown in fig. 2, the fixing grooves 41 are formed in the middle part of the moving blade 40 in the width direction, and the number of the fixing grooves 41 is at least two, and the two fixing grooves 41 are spaced apart along the length direction of the moving blade 40; the number and the positions of the connecting ribs 31 correspond to those of the fixing grooves 41, and each connecting rib 31 is fixedly matched with each fixing groove 41. Thus, the connection position between the movable blade 40 and the metal connecting piece 30 can be increased, so as to further improve the connection stability.
