Description

Technical Field

[0001] This utility model relates to the field of woodworking machinery technology, specifically to a mother-and-child saw. Background Technology

[0002] Currently, traditional cutting equipment mostly uses a single saw blade structure, achieving board cutting through manual or electric adjustment. Such equipment requires frequent saw blade changes or parameter adjustments for complex processing tasks (such as chamfering and multi-angle cutting), resulting in low efficiency. Furthermore, the sawdust generated during cutting is difficult to collect effectively, affecting the cleanliness of the working environment, and traditional guide structures are prone to insufficient cutting accuracy due to board misalignment.

[0003] In existing technologies, saw blade height adjustment relies on a single mode (manual or electric), which lacks flexibility; when the mother and daughter saws work together, it is difficult to maintain coplanar accuracy, which can easily lead to processing errors; the dust collection device is separated from the cutting structure, resulting in low integration and poor cleaning efficiency; the guiding mechanism lacks dynamic locking function, and the cutting path is prone to deviation.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content
