New description: [New technical field] This is a kind of ball screw device, especially a ball screw which is easy to install and has a wiping device consisting of a detachable kit and a scraping device. The annular groove formed on the outer circumference is matched with the fixing hole of the nut, so that it can be stabilized without fixing the position, and the separate structure makes it easy to replace after the brush is worn. [Prior Art] The scraping device of the conventional ball screw is made of plastic material, and there is also a wiping device composed of two materials, which has better scraping effect than the former, and the two are fixed. The main method is that the screw is inserted through the nut to the hole of the brush-mounting device, and the main disadvantage of the configuration is that the excessive tightening of the screw easily causes the deformation of the wiping device to affect its function, so to prevent this from happening, Generally, after the fixing screw is locked, it will be retracted to the proper position, but there is no standard•• distance limitation, and the distance of the exit is too large to effectively fix the brush device, causing the brush device to fall off when the ball screw is actuated. In the case where the wiping device is installed, it is necessary to first mount the tooth on the end of the nut, and then open a screw fixing hole at the opposite position of the nut fixing hole, and then lock the nut on the nut. The method is easy to cause waste of time in assembly, and it is necessary to improve. The use of the ball screw cup to the brush device is also made by injection, wherein the spoon comprises a fixed cover and a brush portion, and the fixed cover is provided with a shell-shaped missing M381010 port at one end for discharging the foreign matter scraped. In addition, in order to prevent the wiping portion from falling off from the fixing cover, a blocking portion is also disposed on the notch end of the fixing cover to prevent the wiping portion from falling off, and the fixing manner is different from the screw fixing, and the positioning pin is disposed on the nut. The hole is further broken into the hole in the fixing cover of the wiping device; the main disadvantage of the structure is that although the pin fixing method can avoid the excessive deformation of the wiping device due to the force applied, the manufacturing method is too complicated and assembled. It is also necessary to align the teeth and the fixing pin holes, resulting in waste of time and improvement.
