According to the attached

drawing

1, 3 show, the outer fixed surface of protection casing 2 in the device installs connecting seat 8, the internal rotation of connecting seat 8 is connected with dwang 9, the fixed cover of surface of dwang 9 has connected connecting plate 10, one side fixed mounting of connecting plate 10 has protective cover 11, protective cover 11 rotates and connects the side at protection casing 2, be equipped with cutting blade 14 between protective cover 11 and the protection casing 2, effect through protective cover 11, can protect cutting blade 14 when not using cutting blade 14 to cut the guide rail, thereby it touches cutting blade 14 that is in naked state to reduce the staff mistake and causes the condition of injury, and this protective cover 11 is transparent material, its turned angle's furthest is ninety degrees.

As shown in fig. 4-5, the device includes a fixing mechanism 12, the fixing mechanism 12 includes a threaded rod 121, a first positioning hole 122 and a second positioning hole 123 are respectively formed on an outer surface of one end of the rotating rod 9, the upper surface of the connecting seat 8 is rotatably connected with the threaded rod 121, a thread of one end of the threaded rod 121 is inserted into the first positioning hole 122 or the second positioning hole 123, a connecting groove 15 is formed on a side surface of the connecting seat 8, a thread of one end of the rotating rod 9, which is provided with the first positioning hole 122 and the second positioning hole 123, is rotatably connected into the connecting groove 15, a threaded hole is formed on the upper surface of the connecting seat 8, one end of the threaded rod 121 is rotatably connected into the connecting groove 15 through the threaded hole, the rotating rod 9 can be fixed by the inserting connection between the threaded rod 121 and the first positioning hole 122 and the second positioning hole 123 formed on the outer surface of the rotating rod 9, so that the protecting cover 11 passing through the fixed state between the connecting plate 10 and the rotating lever 9 is in a fixed state, so as to fix the position of the protecting cover 11.

According to fig. 5, in the device, the first positioning hole 122 and the second positioning hole 123 are perpendicular to each other, the diameters of the first positioning hole 122 and the second positioning hole 123 are equal, when the threaded rod 121 is inserted into the first positioning hole 122, the protective cover 11 and the protective cover 2 are in a parallel state, at this time, the protective cover 11 covers the cutting blade 14, when the threaded rod 121 is inserted into the second positioning hole 123, the protective cover 11 and the protective cover 2 are in a perpendicular state, at this time, the cutting blade 14 is in an exposed state.

The working principle is as follows:

this cutting device is when initial condition, is in the parallel state between protective cover 11 and the protection casing 2, and protective cover 11 shelters from cutting blade 14 this moment, and the threaded rod 121 that connecting seat 8 upper surface was rotated and is connected this moment pegs graft in the inside of the first locating hole 122 that the dwang 9 surface was seted up.

Furthermore, when cutting the guide rail of the elevator, a worker can firstly place the guide rail to be cut on an operation platform in the elevator shaft, then, threaded rod 121 mounted on the upper surface of coupling holder 8 may be rotated, so that threaded rod 121 is gradually removed from the inside of coupling holder 8, so that one end of the threaded rod 121 is moved out of the interior of the first positioning hole 122 formed in the outer surface of the rotating lever 9, so that the rotating lever 9 is in a movable state, then the protective cover 11 is rotated clockwise ninety degrees by taking the rotating rod 9 as an axis, so that the protective cover 11 and the protective cover 2 are in a vertical state, at the moment, the cutting blade 14 rotating inside the protective cover 2 is in an exposed state, then, the threaded rod 121 is rotated again, so that the threaded rod 121 is inserted into the second positioning hole 123 formed in the outer surface of the rotating rod 9, and the protective cover 2 and the protective cover 11 are kept in a fixed vertical state.

Further, after cutting blade 14 is in the naked state, the staff can hold handle 4 and supplementary handle 6 and take up this cutting machine wholly this moment, press the switch 5 of handle 4 one side installation afterwards for motor 3 drives axostylus axostyle 13 and rotates, thereby makes the cutting blade 14 of axostylus axostyle 13 one end surface mounting rotate, carries out the cutting operation to the guide rail of required cutting through cutting blade 14 afterwards.

Finally, after the guide rail cutting is completed, the protective cover 11 can be rotated by ninety degrees anticlockwise to restore the original state, so that the cutting blade 14 is shielded, and when a worker stands on the operating platform to install the cut guide rail in the elevator shaft, the situation that the cutting blade 14 in the exposed state is touched by mistake to cause injury can not occur.

The foregoing shows and describes the general principles and broad features of the present invention and advantages thereof.
