At the same time, the slide block 12, the connecting rod 9, and the triangular block 8 are interlocked and moved, whereby the cutting block 5 moves upward, and the connecting spring 11 and the return spring 4 are compressed, thereby creating an external space. Communicating with the pressurizing chamber 3, the friction block 53 slowly descends under the action of friction and gravity, the exhaust hole 13 is not communicating with the exhaust pipe 24, and the push block is pushed quickly to push the piston 20. By moving downward, the portion of the telescopic rod 15 located in the external space is gradually lengthened, and the telescopic spring 18 is compressed.

When shortening the device, the push block 40 is pushed for a long time, the friction block 53 is gradually lowered, the closing block 23 is lowered and interlocked by the friction rod 49, the exhaust hole 13 communicates with the exhaust pipe 24, and the piston 20 and the telescopic spring. 18 and 18 are restored, and then the push block 40 is rotated to restore the device.

The beneficial effect of the present invention is: The device is simple to configure and convenient to operate, and when used, it can complete the expansion and contraction of the coffee spoon through the operation according to the customer's needs, and also control the length of expansion and contraction. Can meet the needs for coffee spoons when using coffee cups of different depths, expand the scope of coffee spoons, and after stretching and contracting this coffee spoon compared to traditional stretchable coffee spoons The stability of the shape can still be guaranteed.
