[0061] Principle: The curved design of the handle is designed to provide a comfortable grip and make operation easier.

[0062] Connection relationship: The handle is connected to the roller cutter and the punching mechanism, serving as the handheld part of the entire device.

[0063] Roller cutter:

[0064] Principle: The roller cutter is located on the top of the handle and cuts into the surface of the polyurethane material transport hose by rotating.

[0065] Connection relationship: The roller cutter is directly fixed on the top of the handle and connected to the handle through a rotating shaft.

[0066] Stamping mechanism:

[0067] Principle: The punching mechanism is located on the side of the handle, and the surface of the hose cut by the roller cutter is punched through by punching to complete the final cutting.

[0068] Connection relationship: The stamping mechanism is fixed on the side of the handle, tightly connected to the side of the handle, fixed by a fixing part, and connected to the stamping part by a tension spring.

[0069] Improvement plan:

[0070] Improvement of stamping mechanism: comprising a fixing part, a tension spring and a stamping part. The fixing part is connected to the tension spring through a through hole, and one side of the tension spring is connected to the stamping part.

[0074] Handle design: The handle surface is provided with threaded protrusions and is made of rubber material to increase the friction with the operator's hand and improve the operating comfort.

[0075] Specifically, the principle of the utility model is:

[0076] Step 1: Prepare the Cutting Device

[0077] Make sure the unit is in good condition, especially check that the handle, roller cutter and punch mechanism are functioning properly. Make sure the threaded projections on the handle provide a good grip.

[0078] Step 2: Select the cutting location

[0079] Select the location on the polyurethane material transport hose where you want to cut based on actual needs. Make sure there is no debris or obvious damage at the cutting location.

[0080] Step 3: Position the Roller Cutter

[0081] Place the unit's roller cutter in the chosen location. Since the roller cutter has teeth, this increases friction and makes it easier to enter the hose.

[0082] Step 4: Start Rotating the Roller Cutter

[0083] Hold the handle with one hand and cut the hose with the roller knife on the rotating shaft. At this time, ensure that the operation is stable and rotates at a constant speed to avoid excessive force.

[0084] Step 5: Cut the Hose

[0085] During the rotation, the roller cutter will gradually cut into the hose and continue to rotate until the hose is cut to a sufficient depth. At this point, you can use slight pressure to guide the roller cutter to continue cutting.

[0086] Step 6: Punch the Hose

[0087] When the roller cutter completes the initial cut, the punching mechanism completes the final cut. Since the punching part is made of memory metal, it can automatically adjust according to the outer diameter of the hose to ensure accurate punching of the hose.

[0088] Step 7: Securing the Punch Mechanism

[0089] Ensure that the fixings, tension springs and other parts in the punching mechanism operate normally. The gap between the fixings and the punching parts ensures flexible operation and prevents over-punching.

[0090] Step 8: Finish Cutting

[0091] Apply punching force by stretching the spring until the hose is completely cut off. Pay attention to safety during use to avoid pinching or cutting your fingers.

[0092] Step 9: Clean and Inspect

[0093] After cutting, clean the hose from the cut debris and check whether the various parts of the device are damaged or loose.

[0094] Step 10: Organize and store

[0095] After confirming that the device is intact, store it properly to avoid damage and dust accumulation.
