Description

Technical Field

[0001] The utility model relates to the technical field of cutting machines, in particular to a cutting machine capable of preventing a cutting blade from being damaged. Background Art

[0002] As a common cutting tool, cutting machines are widely used in both metal and non-metal industries. These include desktop cutting machines, which consist of a cutting table and a cutting device mounted on the table. Generally, desktop cutting machines are bulky and difficult to carry.

[0003] When using an existing cutting machine, the worker usually presses down the circular saw by holding the handle of the circular saw part, so that the circular saw part cuts the workpiece to be processed. However, after the cutting is completed, in order to separate the circular saw part from the workpiece to be processed, the worker needs to lift the circular saw part again, which increases the worker's workload. At the same time, the cutting blade is easily clamped when it is lifted, causing damage to the cutting blade. Therefore, we propose a cutting machine that prevents the cutting blade from being damaged. Utility Model Content

After fixing, the pipe fitting can be prevented from moving after cutting and damaging the cutting disc;

[0014] 2. After fixing the pipe fitting, press the handle to make the cutting assembly move downward to cut the pipe fitting. In the process of the cutting assembly moving downward, it will drive the two gears to rotate, and the rotation of the two gears will drive the two tooth plates to move upward. The upward movement of the two tooth plates will pull the two steel ropes to move, thereby causing the two springs to contract. After the cutting is completed, the two steel ropes can be driven to reset under the action of the two springs. In this case, the cutting assembly can automatically move upward to reset, which not only reduces the workload of the staff, but also prevents the cutting blade from being clamped and damaged.
