[0003] Traditional cutting devices mostly employ a fixed clamping structure. The workpiece is first positioned and secured using clamps, and then the cutting tool completes the machining process. However, in actual production, when dealing with parts of different sizes, especially larger workpieces, this fixed clamping structure, due to its fixed and non-adjustable clamping mechanism, often requires operators to change clamps of different specifications or adjust the workpiece's clamping posture to adapt to the cutting position. This series of operations is not only cumbersome and time-consuming, but also reduces the operator's work efficiency. Summary of the Invention

Both ends of the lead screw are rotatably connected to the base. The lead screw nut of the lead screw assembly is fixedly connected to the horizontal section of the L-shaped bracket. The horizontal section of the bracket is slidably connected to the base through an outer sliding groove.

[0011] Compared with the prior art, the beneficial effects of this utility model are: This invention utilizes a sliding connection between the movable block and the base, along with a limiting mechanism, to achieve adjustable clamping position to accommodate the cutting needs of parts of different sizes. This avoids frequent fixture changes or workpiece posture adjustments, improving operational efficiency. A lead screw assembly and motor drive ensure precise movement of the cutting mechanism, guaranteeing accurate matching between the cutting and workpiece positions, thus improving cutting precision and processing quality. The clamping mechanism employs a V-shaped structure and anti-slip groove design to enhance workpiece clamping stability and prevent slippage during processing.

The limiting mechanism, through spring reset and toothed plate groove engagement, enables rapid locking and releasing of the clamping position, making operation simple and efficient. This invention solves the problems of cumbersome operation and low efficiency inherent in traditional fixed clamping structures, meeting the dual requirements of precision and efficiency in mechanical engineering parts processing.
