Slip assembly and bridge plug

The invention relates to the field of mechanical structures, aims to solve the problem that an existing slip structure is prone to happening lateral offset or slip sitting is prone to being insecure and instable, and provides a slip assembly and a bridge plug. The slip structure comprises a central tube, end pieces and a plurality of slip sheets; the front end of the central tube is arranged to bea tube head section, the center of the tube head section inwards concaves to form a sliding hole, the outer circumference edge of the tube head section is provided with a plurality of circumferentially-distributed sliding grooves, and the bottom surfaces of the sliding grooves are outward sliding slopes; the end pieces include a front end head portion and a rear sliding shaft portion, and the sliding shaft portion is slidably matched into the sliding hole of the central tube in the axial direction; the rear end faces of the inner sides of the slip sheets in the radial direction are in wedge fit with the sliding slope
