[0002] MPP cable protection pipe, also known as MPP power pipe, MPP pipe, or MPP power cable protection pipe, is a type of pipe made of modified polypropylene as the main raw material for protecting cables. When burying cables, the protection pipe needs to be cut on-site to make it suitable for the burial size.
[0003] Existing MPP protective pipe cutting equipment uses a threaded lifting shearing blade inside a gantry structure. Users manually rotate the threaded rod to lower the shearing blade and cut the pipe. However, due to its narrow main structure, it requires multiple users to step on it for support. Additionally, it lacks a pipe-restricting structure at the bottom, requiring manual support from the user during pipe cutting, making it inconvenient for users.

[0018] Please see Figure 1-5 A field processing and cutting structure for laying MPP cable protection pipes includes a manual cutting tool body 1. An auxiliary cutting mechanism 2 is provided at the bottom of the manual cutting tool body 1. The auxiliary cutting mechanism 2 includes a fixing component 201 and a limiting component 202. The fixing component 201 is provided at the bottom of both sides of the manual cutting tool body 1, and the limiting component 202 is provided at the bottom of the manual cutting tool body 1.

At this time, the limiting plate 202a can receive and restrict the limiting arc rod 202b, the sliding plate 202c, the push rod 202d, and the positioning plate 202e. At the same time, the positioning plate 202e is slidably connected to the edge of the support seat 201c, so that the user can use the push rod 202d to move the sliding plate 202c and the limiting arc rod 202b to contact the pipe surface from the top of the support seat 201c. Then, the user can rotate the positioning plate 202e to contact the inside of the support seat 201c and fix the limiting arc rod 202b by pressing down and friction to reinforce and restrict the MPP cable protection pipe.
[0024] Specifically, such as Figure 1 , Figure 5As shown, an auxiliary component 3 is provided on the front side of the manual cutting tool body 1.

[0026] In this embodiment: by setting the clamping rod 301, spring 302 and anti-slip pad 303, the clamping rod 301, spring 302 and anti-slip pad 303 cooperate with each other to assist the limiting arc rod 202b in clamping and fixing the MPP cable protection pipe, so as to avoid it from shaking during shearing and causing shearing failure.
[0027] Specifically, such as Figure 3 As shown, the top of the inner side of the expansion support frame 201a is provided with a threaded fixing hole, and the inner side of the adjusting base plate 201b is threaded with a fixing bolt.

Simultaneously, the user can install and adjust the base plate 201b according to their arm length, so that the support seat 201c can be installed on top of the extension support frame 201a. At this time, the user can sit on top of the support seat 201c, with their feet on the leverage pedal 201d, allowing them to rotate the top drive handle on both sides of the manual cutting tool body 1 to cut the MPP cable protection pipe. This process reinforces the cut cable protection pipe. When the user installs the limiting plate 202a on the front side of the manual cutting tool body 1, the limiting plate 202a can receive and restrict the limiting arc rod 202b, the sliding plate 202c, the push rod 202d, and the positioning plate 202e. At the same time, the positioning plate 202e is slidably connected to the edge of the support seat 201c, so that the user can use the push rod 202d to move the sliding plate 202c and the limiting arc rod 202b to contact the pipe surface from the top of the support seat 201c. Then, the user can rotate the positioning plate 202e to contact the inside of the support seat 201c and fix the limiting arc rod 202b by pressing down and friction to reinforce and restrict the MPP cable protection pipe.
