[0003] After searching, the Chinese patent publication number CN220197970U discloses a cutting pull saw, which solves the problem that the existing device only cuts when cutting, has a simple structure, cannot adjust the position of objects such as wood to be cut, requires manual positioning, and shakes during the cutting process, which is prone to deviation. The cutting disc for cutting is basically installed by bolts, which is prone to shaking due to uneven force.

[0004] However, this device cannot adjust the tightness of the transmission belt or the height of the cutting blade. When cutting materials of different thicknesses, the height of the cutting blade needs to be adjusted. During the height adjustment of the cutting blade, the vertical movement of the cutting blade will cause the transmission belt to loosen, resulting in a reduction or disappearance of the cutting force of the cutting blade, affecting the cutting effect.

[0005] Therefore, a new solution needs to be proposed to solve this problem. Utility Model Content
