[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Reference Figures 1-4 This utility model provides an embodiment of a power pipe cutter for electrical construction, comprising a support frame 104. The lower part of the support frame 104 has a contact portion 1043, which contacts the inner side of a chain 108. The contact portion 1043 provides downward support to the chain 108 for easy cutting. A handgrip frame 1 is fixedly connected to the left side of the support frame 104 for handheld use. A force-applying rod 101 is fixedly connected to the side of the handgrip frame 1, and the force-applying rod 101 is horizontally positioned. The force bar 101 is located above the cutting motor 102. The left side of the support frame 104 is provided with a lifting groove 113. A slider 111 is slidably connected in the lifting groove 113. A lifting spring 112 is provided in the lifting groove 113. The upper end of the lifting spring 112 is fixedly connected to the slider 111. A lifting sprocket 110 is rotatably connected to the slider 111. The lifting sprocket 110 is located above the drive sprocket 103. A protective shell 2 is provided on the outside of the lifting sprocket 110. The protective shell 2 is used to provide protection and increase the safety of use.

[0023] The protective shell 2 is fixedly mounted on the support frame 104. A cutting motor 102 is fixedly mounted on the lower part of the support frame 104. A drive sprocket 103 is fixedly connected to the output end of the cutting motor 102. A movable plate frame 105 is slidably mounted on the right side of the support frame 104. The support frame 104 is provided with multiple adjustment holes 1041. The movable plate frame 105 is fixedly connected to the support frame 104 through the adjustment holes 1041 by adjusting screws 1042. The movable plate frame 105 is provided with an operating cavity 106 for controlling the movable plate frame 105. 5. Mobility and easy operation: The end of the movable plate frame 105 is rotatably connected to a movable sprocket 107. The movable sprocket 107 is located to the right of the drive sprocket 103. The drive sprocket 103, the lifting sprocket 110 and the movable sprocket 107 are all composed of two component sprocket pieces 1071. The component sprocket pieces 1071 have chain teeth for driving the chain 108 to rotate. The drive sprocket 103, the lifting sprocket 110 and the movable sprocket 107 are connected by a chain 108. Cutting blades 109 are evenly fixed to the outer side of the chain 108.

[0024] The position of the movable sprocket 107 can be changed by the set support frame 104, movable plate frame 105, adjustment hole 1041, and adjustment screw 1042, so as to be suitable for cutting power pipes of different radii and has a wide range of applications.

[0025] In use, the cutting motor 102 is powered on, driving the drive sprocket 103 to rotate. The drive sprocket 103, lifting sprocket 110, and moving sprocket 107 can drive the chain 108 to move. The chain 108 drives the cutting blade 109 to move, thereby enabling the cutting of the power pipe. When it is necessary to adjust the moving sprocket 107, the adjusting screw 1042 is unscrewed to change the position of the moving plate 105. When the moving plate 105 moves outward, it drives the moving sprocket 107 to move outward, which can accommodate power pipes with larger radii. Conversely, it can accommodate power pipes with smaller radii. After moving, the adjusting screw 1042 is used to fix the moving plate 105 back in place, making adjustment convenient.

[0026] Working principle: When in use, the cutting motor 102 is powered on, driving the drive sprocket 103 to rotate. The drive sprocket 103, lifting sprocket 110, and moving sprocket 107 can drive the chain 108 to move. The chain 108 drives the cutting blade 109 to move, thereby enabling the cutting of the power pipe. When it is necessary to adjust the moving sprocket 107, unscrew the adjusting screw 1042 to change the position of the moving plate 105. When the moving plate 105 moves outward, it drives the moving sprocket 107 to move outward, which can accommodate power pipes with larger radii. Conversely, it can accommodate power pipes with smaller radii. After moving, use the adjusting screw 1042 to fix the moving plate 105 back in place. Adjustment is convenient.
