Technical Field

[0001] The utility model relates to the technical field of steel bar rust removal at construction sites, in particular to a handheld vertical steel bar rust removal device. Background Art

[0002] At present, in many construction sites, the steel bars have been tied in place, but the concrete cannot be poured due to various reasons such as the failure to accept the hidden project, weather and rainfall, low temperature, dust control, etc., which makes the vertical steel bars exposed to the air for a long time and causes rust. In view of this situation, before pouring concrete, the site generally uses angle grinders to remove rust manually, which often results in accidents and phenomena such as angle grinders injuring people, inadequate rust removal, and serious dust pollution on the construction site. Summary of the invention

[0003] In order to solve the shortcomings existing in the prior art, the purpose of the utility model is to provide a handheld vertical steel bar rust removal device.
