Pig sleeving device with protection function

The utility model provides a hog nesting device with a protection function, and relates to the technical field of hog nesting devices, the hog nesting device comprises a connecting plate, a U-shaped plate is fixed at one end of the connecting plate, first grooves are formed in the inner walls of the two sides of the U-shaped plate, second grooves are formed in the inner walls of one sides of the first grooves, limiting rods are fixed in the first grooves, and the limiting rods are fixed in the second grooves. The surfaces of the limiting rods are sleeved with T-shaped plates and pushing plates in a sliding mode, and pressure sensors are fixed to the positions, located on one sides of the pushing plates, of the surfaces of the limiting rods. The steel wire pulls the T-shaped plate to slide on the limiting rod, at the moment, the T-shaped plate and the pushing plate extrude the spring, the tension of the spring pushes the pushing plate to extrude the pressure sensor, when the pressure sensor is pressed to a cer
