As shown in fig. 5, the lifting plate 372 has a groove 398, and a magnetic body is disposed in the groove 398, and the groove 398 is arranged in an arc shape. The diameter of the arc formed at the center of each groove 398 is consistent with the diameter range of the iron drum curled edge, it should be noted that the diameter range of the iron drum curled edge is because the iron drum is processed by the curling process, the diameters of the curled edges formed after the curling process are inconsistent to form a diameter range, and the consistency of the diameter of the arc with the diameter range of the iron drum means that the diameter of the arc falls within the diameter range of the curled edge. The slot 398 may be open to the boss 397. Climbing mechanism 30's jacking speed is very fast, stops to the sudden stop when setting for the position with the bucket lifting at climbing mechanism 30, and the ladle body can have the risk of jumping from jacking board 372, and the setting of shape groove 398 and the setting of the interior magnetic body of shape groove 398 can make the iron bucket lift in-process attract the iron bucket, reduce the risk that the iron bucket breaks away from jacking board 372. In addition, the rib module 40 that expands can be outwards outstanding because of the ladle body when expanding the muscle to the iron ladle, and the effect of the rib module 40 that expands and the ladle body can be that the ladle body temporarily separates with jacking board 372 this moment, and at this moment, the fixed separation of magnetic substance to the ladle body need not to destroy any structure, and the effect that also can not produce great power between ladle body and climbing mechanism 30 takes place to warp, consequently, adopts the magnetic substance to attract to have comparable advantage to the iron ladle.

The reciprocating shaft 525 penetrates through the bearing and the clasping device 5241, the clasping screw 5247 is screwed, and the clasping device 5241 is fixed with the reciprocating shaft 525. The bearing housing 526 includes a clasper 5241, so that the bearing housing 526 can support the rotation of the reciprocating shaft 525 and can reciprocate along the length direction of the reciprocating shaft 525 along with the reciprocating shaft 525. The clasping force of the clasping device 5241 is adjusted through the clasping screw 5247, so that the clasping device 5241 and the reciprocating shaft 525 have a good fixing effect.
