As shown in fig. 2 and 6, in the present embodiment, a first through hole 32-1 is formed at the center of the bottom of the sliding block 32 and penetrates upward, and a threaded rod 33-1 at the top of the inverted T-shaped suspension rod 33 sequentially passes through the first through hole 32-1 and a second through hole correspondingly formed at the bottom of the cross beam 1 and is in threaded connection with the fixing nut 7 formed at the top of the cross beam 1, so that the sliding block 33 and the two arcuate clamping arms 35 are integrated with the cross beam 1. Meanwhile, the bottom of the inverted T-shaped suspension rod 33 is also provided with a suspension rod base 33-2. In the embodiment shown in fig. 6, a pair of limit shafts 31-3 are disposed between the slide block 33 and the suspension rod base 33-2. The suspension rod base 33-2 is provided with a compression spring 34 on the upper surface thereof, which is sleeved on the threaded rod 33-1, and in some embodiments, a groove is further provided on the top surface of the suspension rod base 33-2, and the bottom of the compression spring 33 can be inserted into the groove, so that the position of the compression spring 34 is fixed. When the device is unloaded, the compression spring 35 can jack the sliding block 33, so that an adjusting gap is formed between the sliding block 33 and the suspension rod base 34-2, and at the moment, the top ends of the pair of arc-shaped clamping arms 31 can be rotatably adjusted in the adjusting gap so as to ensure that the sliding block 33 and the suspension rod base can be opened back and forth to form an angle matched with an object to be suspended. When the hanging part 31-4 bears, the compression spring 35 is compressed under the action of the gravity of the object to be hung, the sliding block 33 moves downwards along with the compression spring, the arc-shaped clamping arms 31 on the two sides slide inwards along with the compression spring, and clamping force on the two sides of the object to be hung is formed preliminarily. At this time, the pair of stopper shafts 31-3 are also sandwiched between the slide block 32 and the suspension lever base 33-2, and the pair of stopper shafts 31-3 abut on the upper surface of the suspension lever base 33-2. Meanwhile, in the embodiment, the locking nut 35 is arranged between the sliding block 32 and the bottom of the cross beam 1, the locking nut 35 is in threaded connection with the threaded rod body 33-1, after bearing, the locking nut 35 is screwed down, the positions of the pair of limiting shafts 31-3 are further clamped between the sliding block 32 and the suspension rod base 33-2, the positions of the arcuate clamping arms 31 clamped at the left side and the right side of the object to be lifted are also fixed, the pair of arcuate clamping arms 31 form stable clamping force on the object to be lifted, the object to be lifted is lifted at the moment, and the lifted object can be lifted more stably. When the object is unloaded, the locking nut 35 is unscrewed upwards, the hanging part 31-4 is separated from the object to be hung, the pair of arc-shaped clamping arms 31 are opened towards two sides again, and at the moment, the object to be hung can be unloaded.

As shown in fig. 1 and 2, in this embodiment, in order to prevent the object to be hung from falling off during hanging, a plurality of fixing elements 4 for being connected with the object to be hung in a matching manner are arranged inside the first connecting portion 351, and the fixing elements 4 may be fixing pins or buckles or other prior arts.

When the hanger is unloaded, the compression spring 33 can jack up the sliding block 32, so that the front end limiting shafts 31-4 of the two arc-shaped clamping arms 31 and the suspension rod base 33-2 of the inverted T-shaped suspension rod 33 are separated and do not contact. At this time, the two arcuate clamping arms 31 can be driven by external force to open back and forth to form an angle matched with the size of the object to be hung. After the object to be hung is hung on the hanging part 31-4, the compression spring 34 is compressed under the action of the gravity of the object to be hung, the sliding block 32 moves downwards, and the arched hanging arms 31 on the two sides rotate inwards, so that clamping force is formed on the two sides of the object to be hung. Meanwhile, the sliding block 32 and the pair of arc-shaped clamping arms 31 are locked and fixed by threads by screwing the locking nut 35, so that the hung object is clamped, and the stability is higher during hoisting.

The utility model discloses an automatic clamping anticreep hoist can treat the automatic clamping-force that forms of hanging the thing when will treating that the thing is hung, thereby presss from both sides tightly it and prevents that it from droing, safe and reliable more. The lifting appliance does not need to be additionally provided with an additional clamping tool, so that the lifting appliance is simpler in structure, more novel in design and more convenient and faster to operate.

As shown in fig. 2, in the present embodiment, each of the arms of the pair of arcuate clamping arms 31 is provided with an operating handle 5, which is convenient for manual or mechanical operation during working. Meanwhile, the lifting appliance is also provided with an operating wrench 6 for adjusting the locking nut 35 in a matching way, so that manual rotation and screwing can be carried out at any time.
