Description

Technical Field

[0001] The utility model relates to the technical field of cutting saws, in particular to an angle adjustment structure of a cutting saw. Background Art

[0002] A cutting saw is a tool widely used in the industrial and construction fields for cutting various materials such as metals, woods, plastics, stones, etc. Structurally, a cutting saw generally consists of a motor (or a manual driving device), a saw blade, a protection device, a handle, an adjustment device, etc.

[0003] With the development of technology, existing cutting saws can adjust the angle, enabling the wood to be cut with a bevel edge by an inclined saw blade. However, when adjusting in the longitudinal direction, most of these cutting saws adjust the angle of the cutting saw. Due to the large weight of the cutting saw, the greater the adjustment angle of inclination, the greater the shaking generated by the downward pressure of the cutting saw, and the worse the quality of the wood at the cutting position. Therefore, it is necessary to design an angle adjustment structure of a cutting saw to solve the above problems. Content of the Utility Model

[0004] The purpose of the utility model is to solve the defects existing in the prior art, and to propose an angle adjustment structure of a cutting saw.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

A placing plate is fixedly connected to the side wall of the rotating shaft. Limiting mechanisms for restricting the position of the placing plate are arranged on both side walls of the installation frame. The limiting mechanism includes a plurality of tightening screws arranged on the side wall of the installation frame. A friction block is movably arranged on the tightening screw. Two arc-shaped plates are fixedly connected to the lower end of the placing plate. A rotating disc is rotatably connected to the upper end of the placing plate. A second scale disc is arranged on the placing plate. A first scale disc is arranged on the side wall of the installation frame. A fixing mechanism for fixing the wood is arranged on the side wall of the rotating disc.

[0007] Preferably, the fixing mechanism includes two fixing frames fixedly connected to the side wall of the rotating disc. A double-headed screw is rotatably connected to the side wall of the fixing frame. Two clamping plates are arranged on the double-headed screw.
