Manual cat food machine

I have been preparing to make an automatic pet feeding device so that I can feed pets regularly and quantitatively. For various reasons, I was only halfway through the process, so I temporarily changed it to a manual cat food machine. In the actual photo, the black color is not very clear. You can twist a mineral water bottle on top and fill the cat food into the bottle. This way you can see the amount and prevent it from drying out. Perspective view, glue needs to be used between the bracket and the main body. The knob and the screw rod are connected with a hexagon. The protrusion of the knob can be stuck with the groove of the body, and it will not fall off without using a screw. There are 4 pieces in total. You can just change the knob when you change it to electric in the future. It was originally designed to be designed for automatic feeding. Now the function is the same, but it needs to be done manually (dog head??). After all, it still has some uses. For example, I feed cats now. You don’t need to stick your hands when feeding, and you don’t need to wash your hands after feeding. If you say it’s better to just use the bag? But it’s hard to control the quantity when pouring it into a bag, right? Well, I really can’t find any more reasons. At least, I'm using it now and it works very well. 一直在準(zhǔn)備做一個(gè)自動(dòng)給寵物喂食的裝置，這樣就可以定時(shí)定量的給寵物投食，種種原因，只進(jìn)行到一半，所以暫時(shí)改成手動(dòng)貓糧機(jī)好了。 實(shí)物照片，黑色不太清楚，上面可以擰一個(gè)礦泉水瓶子，貓糧灌到瓶子里，既可以看到量，還可以防止變干。 透視圖，支架與主體之間需要用膠水粘。 旋鈕和螺旋桿用六角鏈接，旋鈕的凸起與主體凹槽可以卡住，不用一顆螺絲也不會(huì)掉。 一共4件，日后改電動(dòng)時(shí)候直接換旋鈕即可，原本是準(zhǔn)備設(shè)計(jì)自動(dòng)投喂的，現(xiàn)在功能是一樣的，只是需要手動(dòng)(狗頭??)，畢竟還是有些用處的，比如我現(xiàn)在給貓喂貓糧時(shí)候就不用粘手了，喂完不用洗手，如果你說直接用袋子倒不好么？但是用袋子倒它不好控制量不是么？好吧，我實(shí)在找不到更多理由了。至少，我現(xiàn)在是在用的，還很好用。
