It is a retractable hand tool with a spring that tucks into shell after use to avoid contamination of your pocket. If no spring is used, it will still work.
In addition, a hidden hole is designed to hang on the keyring.
Model of sping: 1093M
Update(2020/04/14):
Add veion2.1 for spring models 1093M and 1091E and veion2.2 for 1093N.
Veion 2 revised the track of the push rod from the original C-type to L-type.
It would increase the strength of shell when italling the spring.

==================================================
這是給不想用手碰電梯鈕之類按鈕的人用的防疫小物。
放彈簧進(jìn)去可以有自動伸縮效果，不放也沒關(guān)係。
另外設(shè)計了一個隱藏式鑰匙圈孔。
建議使用彈簧型號：1093M
更新(2020/04/14):：
新增適用彈簧型號1093M及1091E的v2.1版及適用1093N的V2.2版，第二版修正了推桿的軌道從原來的C型改為L型。這樣在裝彈簧時，外殼軌道部分較不易被弄斷。
更新(2020/04/15)：
第三版修改推桿的軌道改為Z型，並新增了左撇子版及右撇子版的v3.1L及v3.1R
