[0002] Electric welding is a welding operation that uses welding rods to melt the metal parts that need to be connected at high temperature through electric arc. It is more commonly used in the mechanical engineering industry. The plastic-handled brush is a cleaning and grinding tool used in welding work. Grinding is mainly to remove the oxide film on the welding surface of metal materials, or iron filings will adhere to the surface of the material after welding. It is difficult to remove them with an ordinary brush. Some rusty materials also need to be polished and rusted with a plastic-handled brush before processing.

[0003] The plastic handle brush of the prior art consumes a lot in electric welding work, and its structure is mostly one-piece casting, and the brush head and the brush handle cannot be disassembled. If the brush head is worn, the brush handle must be scrapped together, which is quite wasteful. In addition, the existing plastic handle brush can only be cleaned with the brush head, and the means are single and the rust removal effect is not good. For some workpieces with smaller diameters, the arm cannot be inserted, resulting in incomplete cleaning of the inner wall of the workpiece, and due to the cramped space, cleaning is more laborious. Utility Model Content

[0004] The utility model aims to provide a plastic-handled brush with a shovel head for polishing and rust removal. The brush handle and the bristles can be separated and disassembled so that the bristle blocks can be replaced separately, saving resources. A shovel is assembled at one end of the brush handle to cooperate with the bristles for polishing and rust removal, enriching the rust removal methods and achieving better results. The bristle blocks can also slide, so that the plastic-handled brush can be extended so that it can be inserted into workpieces with smaller openings for cleaning, which is more labor-saving and flexible.

[0018] In order to make the purpose and advantages of the utility model more clear, the utility model is specifically described in combination with the following embodiments. It should be understood that the following text is only used to describe one or several specific implementations of the utility model, and does not strictly limit the protection scope of the specific request of the utility model.

[0019] like Figure 1-3As shown, a plastic handle brush with a shovel head for polishing and rust removal comprises a brush handle 1 and a scraper blade 2. A bristle block 101 is slidably connected inside the brush handle 1. The bristle block 101 is slidably embedded with the brush handle 1 through an embedded column 102. The bottom of the bristle block 101 is fixedly connected with bristles 103 in an array. A screw 206 is movably connected inside the brush handle 1 and located above the bristle block 101. A screw tube 210 is rotatably screwed on the outer wall of the screw 206. The brush handle 1 is rotatably connected to the screw tube 210 at the same time. A rotating handle 211 is rotatably connected to the top of the brush handle 1 near one end of the scraper blade 2. A bevel gear 207 is fixedly connected to one end of the rotating handle 211 and located inside the brush handle 1. The outer wall of the screw 206 is rotatably screwed. The brush handle 1 is also rotatably connected to the screw tube 210. The wall is fixedly connected with bevel gear 208, bevel gear 1 207 is meshed with bevel gear 208, one end of screw 206 is rotatably connected with transfer tube 209; the scraper 2 is movably assembled at one end of the brush handle 1, one side of the scraper 2 is fixedly connected with a sub-plate 201, and one end of the bristle block 101 is fixedly connected with a clamping plate 104 for sliding engagement with the sub-plate 201; the middle part of the scraper 2 is detachably rotatably screwed with screw 1 202, screw 1 202 penetrates the sub-plate 201 and is detachably connected with transfer tube 209, the scraper 2 is detachably connected with a fixed seat 203 through screw 205, and the top of the fixed seat 203 is rotatably connected with a pulley 204 in an array.
