Hutonglin, Datong Primary School, Furong District, Changsha City, nowadays more and more people like online shopping, but whether it is the packaging and unpacking staff of the merchants or the buyers, they often encounter the problem of cutting transparent tape: cutting tape with scissors or a knife is not only inconvenient. Moreover, it is easy to get glue on the blade.
Can you invent a simple and practical tape cutter? In combination with the invention, a "ring-shaped tape cutter" composed of a knife holder and a fixing ring is designed, which can effectively solve the problem of tape cutting.
The ring on the cutter is placed on the second knuckle of the right index finger, and then the button on the blade is pressed. After the telescopic blade is pushed out, we can freely cut the tape. When it is used up, the blade is pushed back. Original place.
The ring-shaped tape cutter is small and practical, easy to carry. Its elastic ring is placed over the second knuckle of the index finger, which is stable and does not prevent people from doing other things. The blade is short and sharp, and it can be easily and quickly telescoped into and out of the tool holder. Not only can the transparent tape be cut quickly, but also the contents of the box will not be cut when cutting.
If you often need to cut the scotch tape, do you really want to have such a tape cutter? The instructor Ding Hui, Yongjia City, Yongshui City, Yongshuitan District, Yangjiaqiao Primary School, Tan Junwei, snail snails, the New Year, my family bought a Small metal water tower, ready to be installed on the platform. Out of curiosity, I followed the installer to the platform, and happened to encounter a scene where the installer was smashed and dropped a bolt into the water tower. Only the person drilled into the water tower could find the bolt, the water inlet and the water outlet of the water tower. So small, they can't get in, they can only be anxious.
help. Fortunately, there is no water in the water tower, I can't help them get it.
If you encounter this problem frequently, you will be in trouble. Is there a bolt that can fix the water pipe from the outside? Under the guidance of the new expansion bolt.
The bolt consists of a screw, an expansion sleeve and a nut. The expansion sleeve has three small ends at the expansion end, and the other end has an inner wire and an outer wire, which expands when the screw and the nut are co-extruded.
We drilled a hole in the thin wall of the sealed container, and one end of the new expansion bolt protruded into the container through the small hole. The part of the bolt inside the container expands against the inner side, and the outer part is tightened with a nut, so that the device can be easily fixed. The problem that it is difficult to penetrate the bolt from the inside and tighten the nut on the outside is solved.

With the development of LED, the requirement of brightness of white LED is also getting higher and higher.
In the brightness of the 0.06W LED lamp can reach the highest 8-9LM and 0.2W LED lamp can reach about 24LM. White SMD LED is brighter than the white LED lamp. The power can reach 0.5W 1W 3W. Excellent consistency of the white LED is our advantage.
