Through adopting above-mentioned technical scheme, the mechanic at first overlaps gold jewelry on the locating plate that diameter size is suitable, and the outer wall of locating plate will laminate with gold jewelry's inner wall, and the motor is started afterwards and is rotated the location axle, and connecting plate, locating plate and gold jewelry will take place the rotation along with the location axle is synchronous, and all locating plates can be driven outwards to open the mechanism immediately to realize the tight effect of propping up to gold jewelry, promoted the stability between gold jewelry and the location axle. In addition, when the locating shaft rotates at a high speed, the connecting plate and the locating plate have a tendency to be outwards opened under the action of centrifugal force, and the gold jewelry can be tightly supported, so that the stability between the gold jewelry and the locating shaft is further enhanced. The technical scheme utilizes the arrangement of the connecting plate, the locating plate, the rotating shaft and the opening mechanism, firstly facilitates a craftsman to install gold jewelry, secondly increases the contact area between the gold jewelry and the locating shaft, protects the gold jewelry, improves the stability of the gold jewelry in the processing process, and thirdly can further lock the gold jewelry when the locating shaft rotates at a high speed, so that the gold jewelry can be firmly located on the locating shaft.
Preferably, the opening mechanism comprises a sliding sleeve sleeved on the side wall of the positioning shaft, a connecting rod hinged between the sliding sleeve and the positioning plate and used for driving a plurality of positioning plates in the same group to rotate, a reset spring arranged between the positioning shaft and the sliding sleeve and used for keeping the positioning plate and the positioning shaft coaxial, and a driving piece arranged on the sliding sleeve and used for enabling the sliding sleeve to compress the reset spring and automatically slide to the rotating shaft when the positioning shaft rotates.
Through adopting above-mentioned technical scheme, when the location axle is rotatory, the driving piece will order about sliding sleeve compression reset spring and automatic slip to the pivot, and the connecting rod changes vertical state from the incline gradually, and the connecting rod will jack up polylith connecting plate and polylith locating plate in the same group, and the locating plate just can successfully outwards rotate and prop up the inner wall of tight gold jewelry. When the rotating speed of the positioning shaft is reduced or even stopped, the reset spring pushes the sliding sleeve, the positioning rod puts down a plurality of connecting plates and a plurality of positioning plates in the same group, the positioning plates do not support the gold jewelry, and a craftsman can take off the gold jewelry smoothly.

By adopting the technical scheme, when the positioning shaft does not rotate, the control mechanism drives the clamping column to be contracted in the groove, and the gold jewelry can be smoothly sleeved on the positioning plate. When the locating shaft rotates at a high speed, the control mechanism can cancel the position constraint of the clamping columns, the locking spring can push the corresponding clamping columns out of the grooves, a part of the clamping columns can directly prop against the inner wall of the gold jewelry, the stability of the gold jewelry is further improved, the other part of the clamping columns can penetrate out of the grooves to limit the gold jewelry to be separated from the locating plate, and the gold jewelry can be firmly located on the locating plate.
Preferably, the clamping column is arranged as an iron column; the control mechanism comprises a centrifugal groove arranged on the positioning plate, one end of the centrifugal groove is close to the positioning shaft and is positioned in the same radial direction of the positioning shaft with the plurality of grooves, the other end of the centrifugal groove is far away from the positioning shaft, and the two ends of the centrifugal groove are not positioned in the same radial direction of the positioning shaft; the control mechanism also comprises a magnet block which is embedded in the centrifugal groove in a sliding way and always keeps attraction with the clamping column.
Through adopting above-mentioned technical scheme, when the locating shaft did not take place to rotate, the magnet piece was located the one end that the centrifugal groove was close to the locating shaft, and the magnet piece is the biggest to the appeal of card post this moment, and card post just can compress locking spring and contract in the recess. When the locating shaft rotates, the magnet blocks slide to one end of the centrifugal groove away from the locating shaft due to inertia, and meanwhile, due to the fact that the magnet blocks are subjected to centrifugal force, the magnet blocks are always located at one end of the centrifugal groove away from the locating shaft, and the attraction force of the magnet blocks on the clamping columns is smaller than the elastic force of the locking springs on the clamping columns, so that the locking springs can push the clamping columns out of the grooves. When the rotation speed of the positioning shaft is reduced or even stopped, the magnet blocks slide to one end of the centrifugal groove, which is close to the positioning shaft, again under the mutual attraction of the magnet blocks and the clamping columns, so that the reset is realized. The control mechanism utilizes the centrifugal force to realize automatic control of the clamping column position, is flexible and smart in structure and brings convenience for a craftsman to assemble and disassemble gold jewelry.
Preferably, the positioning plate is provided with a scale groove for displaying the diameter of the positioning plate.
