Description

A kind of grinding device for coating wall cut-off rule

Technical field

The utility model relates to building implement technical field, specially a kind of grinding device for coating wall cut-off rule.

Background technique

For safety and environmental protection, more and more external walls largely use exterior coating, first is that beautiful, second is that heat preservation or It is heat-insulated.In order to enable exterior wall to reach the stereoscopic effect as ceramic tile as stone material, construction party is not often complete in exterior coating Exsiccation when by manually extruding the isolation lines of trench, looking far into the distance is like the ceramic tile or stone the same by one piece of block size specification The stereoscopic effect that material posts.After isolation lines are worked it out, in order to allow lines to seem more three-dimensional more attractive.

Traditional way is：One section of plastic tube is taken, then encases plastic tube with sand paper, then pinched with two hands by construction personnel The plastic tube that firmly sand paper encases carries out friction beauty repair process on exterior coating shielding wire, because sand paper is not to be fixed on modeling In expects pipe, the weight of tool itself is again light, and when construction just needs construction personnel both to clutch using a large amount of strength, then with energetically It goes to repair isolation lines, construction gets up to take time and effort, the suitable height of cost of labor, and this tool and method are not applied people very much Member welcomes.For this purpose, it is proposed that a kind of grinding device for coating wall cut-off rule.

Utility model content

The purpose of this utility model is to provide a kind of grinding devices for coating wall cut-off rule, and sand paper is passed through spring Folder is fixed on metal bar, and construction personnel removes fixed sand paper without additional flower strength, whole-heartedly all one's effort in polishing, add The weight of metal bar itself, construction personnel will be more laborsaving when constructing, very convenient using rising, to solve above-mentioned background technique The problem of middle proposition.

To achieve the above object, the utility model provides the following technical solutions：A kind of polishing for coating wall cut-off rule Device, including metal bar and support rod, the support rod both ends are equipped with screw thread, and threaded hole is equipped in the middle part of the metal bar, described The threaded connection of threaded hole and support rod one end, the other end of the support rod are threadedly coupled with the side of handle, the handle Outside be bonded with foam-rubber cushion, rubber layer is socketed on the outside of the foam-rubber cushion, the both ends of the metal bar are symmetrically welded with U-shaped Shape metal frame is respectively and fixedly provided with spring clip on the upside of the U-shaped metal frame, and the two sides of the metal bar are equipped with dust excluding plate, described The both ends of dust excluding plate, which are screwed between metal bar both ends, the two sides and dust excluding plate of the metal bar, is equipped with gap, institute It states and bracelet is connected with by stretch cord between U-shaped metal frame and U-shaped metal frame.

Preferably, the surface of the rubber layer is equipped with anti-skid chequer, and side is equipped with the first groove.

Preferably, the upper end of the support rod is equipped with the second groove.

Preferably, the both ends of the metal bar are semicircular structure.

Preferably, the threaded hole of the screw thread and handle and metal bar at the support rod both ends matches.

Preferably, the inside of the bracelet is equipped with rubber mount.

Compared with prior art, the utility model has the beneficial effects that：

1, sand paper is fixed on metal bar by the spring clip in U-shaped metal frame, makes its sand paper not by the utility model Easy to fall off, spring clip crystallized ability is good, is also conducive to the replacement of sand paper, and due to the weight of metal bar itself, when polishing reduces physical strength It pays, the dust excluding plate of metal bar two sides can reduce human body sucking, protection health with blocks dust；

2, the utility model production is simple, and low in cost, easy to operate, working efficiency greatly improves, to substantially reduce Cost of labor can select different materials to replace metal bar, also can choose different sizes, pass through according to different constructions Bracelet is connected with by stretch cord between U-shaped metal frame and U-shaped metal frame, can be fallen to avoid tool when high altitude operation.
