The engineer shovel is the conventional equipment of the engineer. For the purpose of facilitating military operations, many engineering shovels contain multiple functions such as shovel, pickaxe, saw, and some have added a bottle opening function. Many engineering shovels are designed to be foldable for easy carrying. It was originally used for military functions, but later the engineer shovel was also often used in ordinary mountaineering, camping and other activities or gardening, disaster relief and other work. The current military engineer shovel is the third-generation engineer shovel, and its identification method is as follows:
1. First of all, the paint is wrong. Small vendors dare not use real military green. People can't see it anyway. The first, second and third generations of real shovel only have military green on the shovel surface, and the third-generation handles and connecting rods are both. Black.
2. Secondly, the appearance of the imitation shovel is outrageous, and there are all kinds of them. Taking the three generations of shovel as an example, some people sell "flat-head military shovel" and "pointed military shovel". Military equipment is the most durable and reliable. It is important to know that the sharper the shovel head, the more the force will be applied. The smaller the force surface, the greater the force. Also look at the handle part. The real military shovel has a very weird corner, which is the strongest mechanically, avoiding wavy wrinkles, and the manufacturing process of this shape is difficult to achieve. Compared to imitations, there are similar shapes in comparison, but they look like they are folded.
3. For the technical parameters of the engineer shovel, the imitation trader can buy a real shovel and can make exactly the same, but he still can't do one thing: that is the detailed index of the product after mass production! The most important thing for mass production of this kind of steel products is the mold. The cost of accurate molds is very expensive. Only the molds are good and do not deform after years of use can guarantee the production of high-quality products. Military factories have to produce for more than ten years without changing molds. Under normal circumstances, the fake production line has errors before production, and after a few productions, the error is getting bigger and bigger. And as long as it is any two of the same type of shovel produced by the 6411 military factory, even if the production date differs by several years, the error rate will not exceed 1 mm.
4. The strength of the engineer shovel. The production process of the real engineer shovel shovel head and pickaxe has changed the internal molecular structure, which can make the shovel face not bounce, crack or deform after being bent at 45 degrees for 3000 times. It has super strength. The flexibility; while having flexibility, its hardness is not achievable by ordinary shovel. A real engineer shovel can easily cut off the 8# steel wire (like the thickness of the connecting line of a laptop, which is slightly thinner than the network cable.), and the shovel The head will not be damaged. Many imitation shovels can meet one of the standards of toughness and hardness, but they cannot break through the two-in-one problem.
