Description

Technical Field

[0001] The utility model relates to the technical field of saw blades, in particular to a small-tooth bimetallic saw blade for bidirectional cutting. Background Art

[0002] A bi-directional cutting small-tooth bimetal saw blade is a tool for metal cutting, with a small tooth profile and capable of bi-directional cutting of metal. It usually includes a saw blade, a tooth pitch, an operating handle, and a saw blade coating. This bimetal saw blade is designed to be bi-directional, which means that it can cut metal in both directions, and can effectively cut whether moving forward or backward. The tooth profile on the saw blade is relatively small, which makes it suitable for precise cutting of small metal parts or thinner metal sheets, providing higher precision and more delicate cutting. This saw blade usually adopts a bimetallic construction, that is, it is composed of two different metal materials, one of which is usually high-speed steel, which provides cutting hardness and wear resistance, and the other metal may be a softer steel or alloy, which provides the toughness and elasticity of the saw blade.

[0003] In the prior art, saw blades are generally unidirectional saw blades, which can only cut in the same direction during use and cannot achieve bidirectional cutting, resulting in a long cutting process and low cutting efficiency. Utility Model Content

[0011] Preferably, a slot is provided inside the fixing frame, one end of the spring is fixedly connected to the inner wall of the slot, and the outer wall of the blocking sheet is slidably connected to the inner wall of the slot.

[0012] Preferably, a slide groove is provided inside the fixing frame, the outer wall of the saw blade body is slidably connected to the inner wall of the slide groove, and the outer wall of the shockproof layer is slidably connected to the inner wall of the slide groove.

[0013] Preferably, the outer wall of the handle is provided with a rubber sleeve.

[0014] The utility model has the following beneficial effects:

[0015] 1. In the utility model, by arranging the first tooth tip and the second tooth tip at the lower end of the saw blade, the sawing paths of the first tooth tip and the second tooth tip are uniform to make the saw surface flat. By arranging the first tooth tip and the second tooth tip in parallel at the lower end of the saw blade, metal can be cut in two directions. Whether moving forward or backward, cutting can be performed effectively, thereby achieving two-way cutting, reducing time consumption, and improving work efficiency.

[0016] 2. In the utility model, the handle can be pulled to drive the clamping column to slide on the inner wall of the fixing frame, and the sliding of the handle can drive the blocking plate to slide, thereby squeezing the spring, so that the clamping column can slide out of the inner wall of the saw blade body and the shockproof layer. After the clamping column slides out, the saw blade body can be slid out from the inner wall of the fixing frame 7 and removed, and conversely, the saw blade body can be slid into the fixing frame, and then the handle is released to allow the spring to rebound and fix the saw blade body and the fixing frame together, thereby achieving the effect of convenient disassembly and replacement of the saw blade body.
