Problems solved by technology
[0002] Mailboxes are carriers for storing letters. People often use them in their daily lives. When processing letterboxes, the outer surface needs to be polished to increase the surface smoothness of the letterbox. Traditionally, manual hand-held grinders are used. work, its work efficiency is low, and a large amount of debris will be produced during grinding, which is harmful to the human body. Therefore, there is an urgent need for a safe, efficient and high-quality letterbox device

The invention discloses a letter box device. The letter box device comprises a main seat body. Support feet are fixedly arranged on the bottom end face of the main seat body and mounted in an inclinedmanner. A storage cavity is formed in an inner wall body of the main seat body. A mounting connection seat is mounted on the bottom end wall of the storage cavity in a sliding-fit manner. A mountingconnection cavity is formed in the top end face of the mounting connection seat. Sunken cavities are symmetrically formed in the inner walls of the left side and the right side of the mounting connection cavity. An elastic strip is fixedly arranged in each sunken cavity. Pushing and pressing plates are mounted in the mounting connection cavity in a sliding-fit manner, wherein the pushing and pressing plates are fixedly connected with the elastic strips at the left side and the right side. A storage connection cavity is formed in the portion, at the bottom end of the mounting connection cavity,in the mounting connection seat. A grid strip is arranged between the storage connection cavity and the mounting connection cavity. A valve is arranged at the bottom end of the right side of the storage connection cavity, wherein the valve penetrates the end face of the right side of the mounting connection seat. A notch is formed in the end face of the right side of the main seat body in a manner that the notch communicates with the storage cavity. A first sliding cavity is formed in the bottom wall inside the storage cavity. A sliding block is mounted in the first sliding cavity in a sliding-fit manner.
