Description
Technical field
The invention belongs to power tools technology field, it is related to a kind of grinding, cutting, grinding apparatus more particularly to a kind of band
There are the angle grinder and its application method of universal joint.
Background technique
Angle grinder, also known as grinder or disc mill are one for cutting and polishing for components such as metal, stone material, glass reinforced plastics
Kind electric tool is mainly used for cutting, grinding and brushing metal and stone material etc..It is divided into pneumatic and electronic two major classes.Electric angle mill
Machine is exactly to be carried out using high-speed rotating disc wheel and elastic grinding wheel, wire wheel etc. to metal component, stone material, glass reinforced plastic etc.
Grinding, cutting, derusting, polishing processing.Suitable attachment is installed on such machine, grinding and polishing operation can also be carried out.
In construction projects, usually using plank sheathing production concrete masonry or component.Thus the problem of bringing is: demoulding
Back stay needs to cut off；Concrete surface is inevitably present rough defect, and need to polish repairing.Ordinary circumstance
Under, ordinary residence layer height is about 2.8 meters, and public building is different depending on the application, and layer height is often higher, therefore, to its top plate
Gate-type frame need to be set up when carrying out pull rod excision and polishing operation with eminence wall, worker, which places oneself in the midst of, carries out operation on gate-type frame.Though
Right gate-type frame bottom has that wheel is easy to remove, but its layer high fixed, and it is inadequate often to will appear a layer height, and two layers of height is spent
Height interferes the case where worker operation.
The solution of the prior art is that worker places oneself in the midst of on gate-type frame, while angle grinder being bundled on rod and is beaten
Grind operation.Thus the problem of bringing is: 1, worker need to constantly move gate-type frame or the different suitable length rods of replacement when operation,
It is unfavorable for working continuously；2, angle grinder is bundled on rod using rope merely, and dust is larger when use, is unfavorable for seeing whether
There is the case where loosening and wire intertwist, there are security risks；3, cable can not be adjusted the angle freely, and cable joint-box is easy broken
Damage；4, under some operating conditions, since operating space is limited, and the grinding of the angle of angle grinder can not change tilt angle, to influence
