Detailed Description

The utility model is further illustrated by the following examples in conjunction with the accompanying drawings:

referring to fig. 1-4, a keycap blanking assembly, comprising:

the connecting top frame is fixed on the injection molding machine 16 and comprises an upper connecting plate 1, at least one sliding rod 2 is fixed below the upper connecting plate 1, a lower connecting plate capable of sliding is fixed on the sliding rod 2, and a supporting piece for supporting the lower connecting plate is also fixed on the sliding rod 2;
