[0022] The present invention has the following beneficial effects:

[0023] When the present invention is in operation, when a shaft workpiece enters the device, the shaft workpiece will come into contact with the elastic sleeve in the clamping component. When the elastic sleeve is rotated under force, the circular arc push rod will be driven to rotate. When the circular arc push rod rotates, it will come into contact with the push vertical plate, pushing the push vertical plate to move forward. When the push vertical plate moves forward, it will push the internal threaded sleeve to rotate along the surface of the external threaded rod and move forward. When the internal threaded sleeve rotates, it will drive the rotating belt on the surface to transmit, and the rotating belt will drive the rotating wheel on the inner wall of the other end to rotate with the rotating wheel The inner wall of the vertical plate rotates, and when the wheel rotates, it drives the gear to rotate. When the gear rotates, through the meshing connection on the surface, it drives the two sets of sliding racks to slide along the inner wall of the fixed slide groove. When the fixed slide groove slides, it drives the stretching splint to run. At this time, the splint will contact and fix the shaft workpiece. At the same time, when the arc push rod runs, it will drive the pull rope to run, pulling the tension spring at the other end of the pull rope to bend. When the tension spring bends, it will drive the clamp block to run, and finally contact the surface of the shaft workpiece and clamp it.

[0024] When the present invention is in operation, when the shaft workpiece enters the device, in the auxiliary clamping component, when the clamping block is in operation, it will drive the pulling block to operate, the pulling block will pull the spring plate to operate, and the spring plate will pull the fixed spring plate to operate. When the fixed spring plate is in operation, it will drive the clamping plates on both sides to operate, thereby generating an auxiliary force on the clamping plates, so that the auxiliary clamping plates can further clamp the shaft workpiece. At the same time, when the internal threaded sleeve is in operation, it will drive the auxiliary rotating wheel to rotate along the inner wall of the anti-loosening vertical plate. When the anti-loosening vertical plate rotates, it will drive the connecting spring plate to operate, and the connecting spring plate will drive the connecting shaft to operate. Because the end face of the connecting shaft is in contact with the surface of the stretching clamping plate, when the stretching clamping plate is in operation, it will generate an auxiliary force on it, thereby assisting it in having a better clamping force on the shaft workpiece.

[0025] When the present invention is in operation, when a shaft workpiece enters the device, it is adsorbed and fixed in the fixing component. When the end face of the shaft workpiece contacts with the adsorption component, the air pump operates to absorb the air in the adsorption port of the air pump, adsorbs the shaft workpiece, and fixes it to a certain extent. Then, the gas in the adsorption port of the air pump enters the rotating air pipe through the adsorption tube of the air pump. At the same time, the air suction pipe mouth adsorbs the gear close to one end of the inner shell to fix it. When the gear is fixed, the fixed slide groove is fixed, and then the clamping plate is stretched and fixed at the end, so that the clamping plate provides auxiliary force for the shaft fixation. Then, air enters the air outlet pipe through the air outlet pipe, and then the adsorption gear is driven to operate by the ejected gas. When the adsorption gear operates, it drives the adsorption rack to operate along the adsorption slide groove through the meshing action. When the adsorption rack operates, it drives the adsorption arc plate to operate, so that it contacts the clamping plate, applies thrust to it, and makes the clamping force of the clamping plate on the shaft workpiece more stable.
