Description

Technical Field

[0001] The utility model relates to the technical field of planing, in particular to a cutting saw capable of preventing sparks from flying. Background Art

[0002] A cutting machine refers to a device used to cut materials, which is usually divided into large machine tools and small manual types. Large machines are efficient, but the cost is also high. Manual cutting is flexible and convenient. The Chinese utility model patent, authorization announcement number "CN219464925U", discloses a new type of cutting device for electromechanical engineering. The new type of cutting device for electromechanical engineering includes a base, a support seat is fixedly connected to the left middle section of the upper surface of the base, a load-bearing rod is hinged at the top of the support seat, a motor is fixedly connected to the middle part of the load-bearing rod, a circular saw blade is fixedly connected to the outer end of the motor shaft, a handle is fixedly connected to the upper end of the load-bearing rod, a switch is fixedly connected to the top of the upper surface of the load-bearing rod, and a transparent shield is fixedly connected to the rear section of the upper surface of the base. The transparent shield design is adopted. Through the mutual cooperation of the handle and the transparent shield, when the circular saw blade is working and cutting, the debris of the material can be resisted to prevent the debris from splashing or bouncing and causing damage. At the same time, it can also resist the influence of sparks during cutting, thereby improving the reliability of the equipment, protecting the health of the operator, and increasing work efficiency.

[0003] The above technical solution is to carry the material on top of the roller and push it so that the front end of the material enters under the circular saw blade, turn the knob to drive the threaded rod to rotate, operate the control panel to power on the equipment, press the handle down to drive the load-bearing rod to be pressed down, and press the switch to power on the motor, so that the circular saw blade rotates and moves downward to complete the material cutting operation. After cutting, lift the handle to complete the reset, turn the knob slightly to loosen the moving clamp, and then the material can be loaded through the roller again, thereby performing a cyclic cutting operation. However, the above technical solution still has certain defects. For example, the above equipment uses a transparent shield to prevent sparks from flying when cutting materials. However, when the transparent shield needs to be removed for cleaning or maintenance after long-term use, the staff needs to carry tools to remove it, which greatly increases the workload of the staff. Utility Model Content

[0023] (1) The spark-proof cutting saw drives the return spring to contract and drives the limit rod to move in the opposite direction by twisting the rotating block in the limit device. Then, the limit rod moves in the opposite direction and disengages from the inside of the limit rod groove, so that the protective cover can be removed from the workbench. This is simple and quick to operate, and it is convenient for workers to remove the protective cover from the workbench, avoiding the need for workers to carry tools to remove the protective cover, effectively reducing the workload of workers and increasing the service life of the protective cover.

[0024] (2) The spark-proof cutting saw places the material on a roller, pushes the material into the protective cover according to the required cutting length, rotates the crank handle to drive the threaded rod to rotate and move it toward the fixed block on the workbench, and then drives the clamping block to approach the fixed block on the workbench to clamp the material. This greatly improves the stability of the equipment during cutting, effectively reduces the deviation of the equipment when cutting the material, and thus greatly improves the practicality and flexibility of the equipment.
