Hole forming device used for melons and fruit

Abstract

The invention discloses a hole forming device used for melons and fruit. The hole forming device comprises a cylindrical hollow barrel. A cuboid lens is embedded in the side face of the barrel. A graduated scale is arranged on the lens. A drill bit communicating with the interior is arranged at one end of the barrel. The drill bit is in a cylindrical shape, and saw teeth are arranged on the periphery of the end portion of the drill bit. The drill bit is made of a ceramic material. A threaded rod is arranged at the other end of the barrel and can rotate into the barrel. The length of the threaded rod is equal to the length of the barrel. The lens with the graduated scale is arranged on the barrel, the hole opening depth can be precisely mastered, and therefore the judgment on the growth vigor of the melons and the fruit is improved; and the drill bit made of the ceramic material is arranged and is firm, durable in use and good in corrosion resistance, and time and labor are saved. In addition, the part material arrangement of the device is scientific and reasonable, the manufacture process is simple, and the hole forming device is green, sanitary and worthy of wide popularization.

Description

technical field [0001] The invention relates to a melon and fruit tool, in particular to a hole opening device for the melon and fruit. Background technique [0002] When identifying melons and fruits, such as watermelons, fruit growers or buyers generally open holes in the melons and fruits, take out a small sample to watch and taste, so as to identify the growth of the melons and fruits, and then combine picking or trading. And at present, the perforating utensil that adopts is generally the utensil that fruit knife is set simply, can only perforate on melon and fruit, and can not accurately grasp the depth of perforation, and the growing state of melon and fruit different depth is different, affects fruit grower or Buyers judge the growth of melons and fruits, and most of the existing perforating utensils are made of metal materials, which are easily corroded and bent during use, and the perforation is laborious. Contents of the invention [0003] Aiming at the deficie...
