In the technical scheme, when the ball to be measured is fixed, the piston head is pushed to the placing end through the piston rod, air in the through cavity is discharged, the ball to be measured is placed at the placing end, and the piston head moves towards one side far away from the placing end through the piston rod, so that pressure difference exists inside and outside the through cavity, and the fixing of the ball to be measured is realized.

As a further arrangement of the utility model, the spring of the driving piston far away from the placing end is also included.

Among the above-mentioned technical scheme, the spring makes the piston automatically keep away from and places the end, convenient operation, and guarantees that the piston rod can not be close to placing the end because of the relation of pressure difference, guarantees that the ball that awaits measuring can be stable fixes placing the end.

As a further setting of the utility model, be equipped with the mounting groove on the base, be equipped with the release link with the piston rod linkage in the mounting groove, the spring sets up between the tank bottom of release link and mounting groove.

Among the above-mentioned technical scheme, the spring is placed in the mounting groove, guarantees that the elasticity direction of spring is unanimous or opposite with the moving direction of piston, and the spring does not lead to the fact the damage with piston direct contact, prevents that the spring from to the piston.

As a further setting of the utility model, place the end and be equipped with the elasticity seat that supplies the ball installation that awaits measuring, the elasticity seat is including the portion of placing of bowl form, the bottom of the portion of placing is equipped with and leads to the through-hole of chamber intercommunication.

Among the above-mentioned technical scheme, the ball that awaits measuring of fixed that the elasticity seat can be better, the portion of placing of bowl form simultaneously can be better with the outer wall laminating of the ball that awaits measuring, make the ball that awaits measuring more stable, convenient follow-up detection.

As a further setting of the utility model, the mounting groove is the ring channel that uses the axis that leads to the chamber as the axle center, the spring sets up with the mounting groove is coaxial.

Among the above-mentioned technical scheme, spring, mounting groove and logical chamber coaxial setting make the whole operation in-process atress of piston stable, can not like one side skew, convenient operation.

The present invention will be further described with reference to the accompanying drawings.
