Further, the arranged outside of first connecting rod, second connecting rod has gum cover, and gum cover one end is arranged on projection outer wall, and the other end is arranged on sleeve outer wall.The setting of gum cover is convenient to extrude first connecting rod, second connecting rod, avoids first connecting rod, second connecting rod to scratch hand.
Further, sleeve comprises interconnective first sleeve, the second sleeve, and the first sleeve, the second sleeve have identical central shaft, internal diameter, and the external diameter of the first sleeve is less than the external diameter of the second sleeve, and described groove is arranged on the sidewall of the first sleeve.Described first set drum outer wall is slightly smaller than the inwall of quartz glass reaction cup, the external diameter of the second sleeve is consistent with projection, the external diameter of the second sleeve is arranged and is greater than the first sleeve outer diameter, be convenient on the one hand coordinating of the second sleeve and projection, guarantee that the second sleeve can not put in quartz glass reaction cup on the other hand, avoid elastic body by excessive compression.
Further, sleeve is provided with end, elastomeric one end and is set to blind end.Avoiding elastic body large in the axially change of sleeve when being squeezed, improving elastic body and becoming large efficiency in sleeve radial direction.
Further, groove is set to cambered surface outwardly in quill 2 ends upwards.Because elastic body is chondritic, chondritic has certain radian, elastic body be squeezed to become in sleeve radial direction protrude from greatly groove time, groove is set to cambered surface in quill end upwards, reduce resistance during elastic body protrusion groove, be conducive to elastic body convex for groove in sleeve footpath.
Further, elastic body is rubber ring.Rubber ring specifically refers to that center is provided with the spherical elastic construction of center pit, is conducive to elastomeric rapid deformation, improves the compression efficiency of elastic body and quartz glass reaction cup.
To sum up, the beneficial effects of the utility model are:
1, the utility model upwards arranges the elastomeric mandrel of extruding by being arranged on quill, being provided with in sleeve lateral wall to allow elastic body become large groove in sleeve radial direction, realize elastic body quartz glass reaction cup inwall Compliant pressure is taken out, guaranteeing, under the prerequisite of taking out quartz glass reaction cup, to avoid the breakage of quartz glass reaction cup.
2, the utility model is by arranging clamp in mandrel end, by the first connecting rod that is hinged, second connecting rod control mandrel on move or move down, realize elastomeric extruding, and then the Compliant pressure realized quartz glass reaction cup, the breakage of quartz glass reaction cup can not only be avoided, and more convenient control extruding elastic body.
