(Reward post on April 11) During the process of disassembling and assembling the equipment, a name was involved: Which part of the cow specifically refers to?

Image word, two objects pushing up against each other, such as two pipes tilting upward to connect

【Word】: Dingniu [phonetic]: dǐng niú 【Definition】: 1. A way of playing dominoes. Two or more families take turns to draw cards, and those with the same number of points are connected to each other. The person who cannot catch up chooses a card from his hand and deducts it. The one who does not deduct the card in the end or deducts the smallest number of points wins. Also called Solitaire. 2. A metaphor for quarrels or conflicts. 3 Oxen fight with their heads against each other. 　　synonymous: disharmony, disharmony synonym: conflict antonym: He explains the terminology of He Yanhe [Ding Niu] Tai Chi. Refers to an incorrect method of exerting force. Both sides of Push Hands violate Tai Chi's martial arts principles of "conquering strength with softness" and "introducing failure" to fight with hard force. This lack of change and loss of flexibility has always been a taboo for boxers. It is named because it looks like a bull with its head on top. When specifically applied to engineering, I understand extension as a state of opposition. I don’t know whether it is the correct answer or not. Please continue the discussion!

Is it a place to put the jack or a place that can be supported?

It's really a new term. I've never heard of it before.

Literally means that the device is moved close to or in contact with another device. Personally, I think: A more reasonable explanation should be that when a piece of equipment is installed or dismantled, the moving space between it and adjacent equipment is small, and there is a minimum position point for disassembly. This point should be the top point of the equipment, which means the minimum assembly space.
