[0018] The technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0019] like Figure 1 as well as Figure 2 As shown, an embodiment of the present invention proposes an insulating rod electric cutter, comprising: a mounting column 1, a telescopic column 3, a mounting box 5, a driving mechanism and a cutter assembly, wherein the top of the mounting column 1 is recessed to form a first slide groove 2, one end of the telescopic column 3 is slidably connected to the first slide groove 2, the telescopic column 3 is locked with the mounting column 1 by a bolt 4, a plurality of mounting holes evenly distributed in the vertical direction and matching the bolt 4 are provided on the telescopic column 3, the mounting box 5 is detachably fixed to the top of the telescopic column 3 by the mounting assembly, the cutter assembly is fixed to the side wall of the mounting box 5, and a driving mechanism is also provided on the mounting box 5, the driving mechanism is used to drive the cutter assembly to cut the cable.

[0020] By slidingly connecting the telescopic column 3 with the mounting column 1 and providing a plurality of mounting holes matching the bolts 4 on the telescopic column 3, it is convenient for operators to reasonably adjust the length of the telescopic rod extending out of the mounting column 1 according to the construction scene, and then adjust the height position of the cutter assembly on the side wall of the mounting box 5 located at the top of the telescopic column 3, so that the insulating rod electric cutter can be suitable for cutting cables of different heights. At the same time, the length adjustment structure of the insulating rod electric cutter (i.e., the mounting column 1 and the telescopic column 3) is simple in structure and easy to operate.

[0021] Furthermore, a rubber protective layer 6 is wrapped around the outer wall of the installation column 1 , and the rubber protective layer 6 plays a role of insulation protection. At the same time, in order to facilitate the operation of the operator, an arc-shaped handle 23 is provided on the side wall of the installation column 1 .

[0022] like Figure 2As shown, the cutter assembly includes: a movable blade 9 and a fixed blade 7, both of which are arc-shaped structures, and the fixed blade 7 is fixed to the side wall of the installation box 5 through a mounting rod 8, and the movable blade 9 is hinged to the fixed blade 7, and the output end of the driving mechanism is connected to the movable blade 9, and the driving mechanism is used to drive the movable blade 9 to move toward the fixed blade 7. The driving mechanism includes: a hydraulic rod 10, a push plate 11 and a connecting rod 12, the hydraulic rod 10 is arranged in the installation box 5, the output end of the hydraulic rod 10 passes through the installation box 5, and the output end of the hydraulic rod 10 is slidably connected to the installation box 5, the push plate 11 is fixed to the end of the output end of the hydraulic rod 10, and the two ends of the connecting rod 12 are respectively hinged to the push plate 11 and the end of the movable blade 9.

[0023] The hydraulic rod 10 drives the push plate 11 to move closer to or away from the movable blade 9. When the hydraulic rod 10 drives the push plate 11 to move closer to the movable blade 9, the connecting rod 12 pushes the movable blade 9 to rotate relative to the fixed blade 7, so that the free end of the movable blade 9 moves closer to the end of the fixed blade 7, so that the movable blade 9 cooperates with the fixed blade 7 to cut the cable. When the hydraulic rod 10 drives the push plate 11 to move in a direction away from the movable blade 9, under the transmission action of the connecting rod 12, the movable blade 9 is driven away from the fixed blade 7, which is convenient for the next cable cutting work. Further, a control panel 24 can be set on the side wall of the mounting column 1, and a controller is set in the control panel 24. The controller is electrically connected to the hydraulic rod 10. A control button 25 is set on the control panel 24, and the control button 25 is electrically connected to the controller, so that the first hydraulic rod 10 can be controlled to work through the control button 25.

[0024] Furthermore, the installation assembly includes: a connecting plate 13 and a mounting plate 14 , the connecting plate 13 is fixed to the bottom of the installation box 5 , and the mounting plate 14 is fixed to the top of the telescopic column 3 , and the connecting plate 13 and the mounting plate 14 are locked by a screw 15 .

[0025] Furthermore, the interior of the installation box 5 is an installation cavity 16, the top of the installation cavity 16 is open, and a cover plate 17 for closing the installation cavity 16 is provided at the opening of the installation box 5, one end of the cover plate 17 is hinged to the top of the installation box 5, and the other end of the cover plate 17 is locked by a locking mechanism provided in the installation cavity 16. By providing an opening at the top of the installation cavity 16, the opening is opened and closed by the cover plate 17, so that the opening is opened by the cover plate 17, so that the hydraulic rod 10 in the installation cavity 16 can be inspected.

[0026] Specifically, Figure 2As shown, the locking mechanism includes: a mounting seat 18, a spring 20 and a limiting column 19. The mounting seat 18 is fixed at the bottom of the mounting cavity 16. The top of the mounting seat 18 is recessed to form a mounting groove. The limiting column 19 is slidably set in the mounting groove. The spring 20 is also set in the mounting groove. A limiting hole for the limiting column 19 to pass through is set on the cover plate 17. The limiting column 19 is inserted into the limiting hole under the elastic force of the spring 20.

[0027] When it is necessary to open the opening at the top of the rotating chamber, it is only necessary to push the limiting column 19 from the top of the limiting hole to push it into the installation chamber 16, and then the free end of the cover plate 17 can be pushed to rotate relative to the installation box 5 to open the opening at the top of the installation chamber 16; further, a second slide groove 21 is provided on the side wall of the mounting seat 18 and the side wall of the installation box 5, and the two second slide grooves 21 are connected.
