Description

Technical Field

[0001] The utility model belongs to the technical field of wall saws, and in particular relates to a double-sided toothed wall saw. Background Art

[0002] Wall saws are an engineering tool consisting of a power station and a saw head. They were originally designed for cutting concrete walls and are used in construction engineering renovations.

[0003] Hydraulic wall saw is a special cutting tool, suitable for cutting hard materials such as reinforced concrete, rock, ceramics, brick walls, etc. It is widely used in opening doors, windows, vents on walls, cutting of reinforced concrete beams and columns, cutting of floor slabs and bridges, and stone processing.

[0004] Most of the existing wall saws on the market are single-sided toothed wall saws, and some double-sided toothed wall saws have teeth of different sizes on both sides, which are easy to jam the saw. After inserting the wall gypsum board, the saw teeth on both sides cannot work at the same time, which brings inconvenience to work and reduces work efficiency. For this reason, we propose a double-sided toothed wall saw. Utility Model Content

[0005] The utility model aims to provide a double-sided toothed wall saw to solve the problem that most of the existing wall saws mentioned in the background technology are single-sided toothed wall saws, and some double-sided toothed wall saws have teeth of different sizes on both sides, which are easy to get stuck. After inserting the wall gypsum board, the saw teeth on both sides cannot work at the same time, which brings inconvenience to work and reduces work efficiency.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a double-sided toothed wall saw, comprising a handle and a saw blade, a slot is provided inside the handle, a block is provided on the top of the saw blade, the block is adapted to the slot, the block is clamped in the slot, the saw blade is wide at the top and narrow at the bottom, saw teeth are provided on both sides of the saw blade, the number of the saw teeth is several, and the specifications of the saw teeth on both sides are the same.

[0007] Preferably, a through hole is provided inside the handle, and a screw is provided inside the through hole.

[0008] Preferably, a circular hole is provided above the handle, and the circular hole passes through the front and rear sides of the handle.

[0009] Preferably, the outer surfaces of both the front and rear sides of the handle are provided with anti-slip grooves, and the number of the anti-slip grooves is several.

[0010] Compared with the prior art, the beneficial effects of the utility model are:

[0011] 1. The utility model product is a double-sided toothed wall saw. After upgrading, the double-sided teeth can save steel, and the size of the double-sided teeth is the same. With the saw blade that is wide at the top and narrow at the bottom, the narrower saw blade at the bottom has less effort and can be inserted into the gypsum board faster. The saw will not get stuck when the saw blade is fully inserted. After the saw blade is inserted into the wall gypsum board, the saw teeth on both sides can work at the same time, which is convenient and greatly improves work efficiency. The wall saw is mainly used to saw gypsum boards used in house decoration, and can also be used to saw branches, wood, water pipes, etc., and is very practical.

[0012] 2. The symmetrical design of the handle allows both sides to be used. The handle is embedded in the saw blade through the set blocks, slots and through holes, and is fixed with screws for higher firmness. The handle has a hollow circular ring design to save materials and facilitate storage and hanging. The handle is designed with anti-slip grooves to prevent the wall saw from slipping when in use.
