Taking the example that the cylinder 310 is disposed downward at one end of the connecting lever 330, please refer to fig. 5 again, when the cylinder 310 is disposed downward, the cylinder 310 extends out and then generates pressure on the first elastic member 321 under the action of the lever 330, the elastic force of the first elastic member 321 is smaller than the elastic force of the second elastic member 322, taking the stress of the cylinder 310 as an initial state, when the cylinder 310 extends out and presses the second elastic member 322 through the lever 330, the pressing plate 211 rises under the influence of the restoring force of the first elastic member 321, the inner supporting pieces 214 are greatly influenced by the limiting hole 110, the plurality of inner supporting pieces 214 are aggregated, and the inner supporting stretching shell 212 is in an aggregated state. When the inner supporting piece 214 of the inner supporting jig is stretched into an inner groove of a product to swing the inner hole in advance, the air cylinder 310 is contracted, the air cylinder 310 releases the force application on the lever 330, the second elastic piece 322 presses the pressing plate 211 downwards, the first elastic piece 321 is compressed under the force, the inner supporting piece 214 has small effect on the limiting hole 110, the inner supporting pieces 214 are expanded, the inner supporting stretching shell 212 is in an expanded state, the inner supporting jig clamps the product and transports the product, the air cylinder 310 is contracted after the inner supporting jig reaches a preset position, the air cylinder 310 stretches out to apply force to the lever 330 again, the second elastic piece 322 is compressed under the force, the first elastic piece 321 lifts the pressing plate 211, the inner supporting piece 214 is polymerized by the inner supporting pieces 214 under the effect of the limiting hole 110, the inner supporting jig is separated from the product, and the product is transported. According to the scheme, the air cylinder 310 only acts on the second elastic piece 322, no force is applied to the inner supporting piece 210, and the part applying force to the inner supporting piece 210 is the second elastic piece 322, so that the second elastic piece 322 applies variable force to the inner supporting piece 210 in the clamping process, the friction force is increased when the inner supporting piece 214 of the inner supporting piece 210 abuts against the inner groove wall or the inner hole wall of the product, the elastic force of the second elastic piece 322 is increased and decreased due to the increased distance, the second elastic piece 322 stops pressing by the pressing plate 211 after the inner supporting piece 214 abuts against the product, the phenomenon that the inner supporting piece 214 is still pressed downwards to generate obvious scratches on the inner groove wall of the product when the inner supporting piece 214 abuts against the inner groove wall of the product is avoided, and the reliability of the product is improved.
