Detailed Description
As can be seen from fig. 1 and 2, the manual separator for girdling the high-voltage cable insulation layer disclosed in the present embodiment mainly comprises a rotary disc 1, a blade 2, an adjusting screw 3, a spring 4 and a positioning sleeve 5.
The rotating shaft 11 of the rotating disc 1 is a T-shaped shaft and is fixedly connected to the axial center of the rotating disc 1, and a section of the small-diameter section of the rotating shaft 11 extends out of the rotating disc 1.
The knife arm of the blade 2 is a crank arm, and the corner of the crank arm is rotatably hinged on the turntable 1 through a pin shaft. The thickness and the angle of the cutting edge of the blade are determined according to actual requirements.
A screw hole seat 6 is fixed above the turntable 1 corresponding to the outer section of the cutter arm, an adjusting screw rod 3 is vertically connected in the screw hole seat, and the lower end face of the adjusting screw rod 3 is an inclined plane matched with the outer section of the cutter arm.
A fixed seat 7 is arranged below the outer section of the cutter arm on the rotary table 1, and the transverse position of the fixed seat is staggered with the screw hole seat 6.
Two ends of the spring 4 are respectively fixed with the fixed seat 7 and the outer section of the knife arm.
