The present invention mainly relates to a grinding device, in particular to a hand-held livestock teeth grinding device.

According to the human, when raising livestock, there is often a need to trim the teeth of livestock. Take pigs as an example. When piglets are born, they have a pair of long and sharp deciduous teeth at the front four corners of their upper and lower jaws, which are the third incisors and canine teeth of piglets, also known as "needle teeth"; these eight sharp deciduous teeth often cause the sow's nipples to be injured when the piglets are suckling, causing the sow to be unwilling to breastfeed, or when the piglets are playing with each other, they scratch the skin of their companions, causing wounds on the piglets' bodies, which in turn leads to subsequent infection problems. Therefore, the sharp deciduous teeth of piglets are usually trimmed within a few hours after sucking colostrum to protect the sow and other piglets.

Among them, tooth scissors were used to trim the teeth of newborn piglets in the early days. However, different tooth-cutting pliers are prone to have different sharpness levels due to wear, and the breeders’ technical level and work proficiency are different. Broken tooth sections, tooth root injuries, and gum bleeding often occur after tooth-cutting. If you are not careful, it is easy to cut the piglet's tongue or mouth. Therefore, in general, using tooth scissors to trim the needle teeth of piglets often causes problems such as tooth root inflammation, gingival redness or ulcers, and oral erosion, which in turn can lead to disease and food refusal in piglets. Even the consequences of death. On the other hand, the teeth of piglets with uneven sections after trimming can easily puncture the sow's udder when sucking, causing the sow's udder inflammation.

In order to improve the above problems, a known teeth grinding device has been available in the market in recent years, which can be inserted into the piglet pincers to be ground and the ends of the pincers can be ground flat by a grinding wheel; for example, a similar known teeth grinding device is disclosed in China Publication No. 1915187.
