Description

Technical Field

[0001] The utility model relates to the technical field of sliding table saws, in particular to a sliding table saw with a protective device. Background Art

[0002] Sliding table saw, also known as panel saw, can be used for longitudinal and cross-cutting of various man-made boards, such as veneer particle board, fiberboard, plywood and solid wood board. It is a common equipment among woodworking machinery. When cutting wood boards, a large amount of waste chips will be splashed, and the splashed waste chips pose a safety hazard to workers.

[0003] Some devices on the market generally start the telescopic rod on the workbench to cause the protective plate to rotate along the rotating seat, and then rotate the connecting rod to drive the limit block to move, so that the threaded pin and the threaded hole are docked, thereby limiting and fixing the protective plate, and then blocking the debris generated during the cutting process to prevent the debris from splashing to the sides of the sliding table saw body and causing damage to the workers passing by the two sides of the sliding table saw body, thereby playing a role in protecting the workers during the operation of the sliding table saw.

[0004] However, in actual use of the above equipment, when a worker pushes a wooden board to perform a push saw, the cutting saw blade is close to the worker's hand, which poses a safety hazard to the worker's hand during operation. In view of this, we propose a push table saw with a protective device. Utility Model Content
