Description
Technical Field
The utility model belongs to the clearance instrument, specifically speaking are a device that stores up debris in the thread groove of screw rod and clear up.
Background
Before the bolt is manufactured, a protective oil film is generally coated on the surface of the bolt to prevent the threads on the screw from being corroded and damaged due to moisture, and meanwhile, the threads are more smooth due to the oil film on the surface when being screwed into the screw hole. However, since the oil film is easy to adhere to impurities such as dust, when the bolt is not stored properly, the impurities are adhered and accumulated in the groove of the thread to prevent screwing installation, and the influence on the bolt is particularly obvious for the bolt with a small screw diameter and a small screw pitch.
At present, the problem that the bolt adhered with impurities is generally solved by manual treatment before use is that a worker holds an iron brush with one hand and pinches the end of the bolt with the other hand, the iron brush is tightly attached to the surface of a thread, and the bolt is rotated to brush and clean brush wires along the thread groove.
The mode has low working efficiency and high labor intensity, is easy to brush hands carelessly and has no way of thoroughly brushing sundries in bolts with small diameter or small thread pitch because the thread grooves of the bolts are narrow; moreover, brushing and scraping the oil film on the surface of the thread by using an iron brush can damage the oil film, the bolt without the oil film can not be smoothly screwed into the screw hole, the screw thread can be broken by overlarge force if the bolt is screwed by applying force, and the bolt and the screw thread on the screw hole can be broken even in serious cases, so that the waste of parts is caused.
