Description

Technical Field

[0001] The invention relates to the technical field of agricultural machinery and equipment, in particular to an electric saw. Background Art

[0002] The electric saw, also known as the "power saw", was invented by German Andreas Steele in 1926. It greatly saves the time and manpower spent on cutting materials. The electric saw uses electricity as a power source and is a cutting tool with sharp teeth on the edge for cutting wood, stone, steel, etc.

[0003] Conventional electric saws generally have a baffle at the rear end of the saw blade to prevent wood chips from splashing onto the operator. However, the baffles on electric saws are mostly fixed and cannot be adjusted. When using an electric saw to cut wood, for safety reasons and to protect the saw blade, the saw is generally cut with the front end of the saw blade. Therefore, when cutting thinner wood, the distance between the cutting point of the wood and the baffle is too large, and wood chips may still splash. Summary of the invention

[0004] In view of the above problems, the present invention provides an electric saw, in which the baffle is movably arranged, so that the position of the baffle can be adjusted according to needs, and wood chips can be prevented from splashing more effectively.

[0005] The technical solution of the present invention is as follows:

[0006] An electric saw comprises a casing, a saw blade is arranged at the front end of the casing, a handle is arranged at the rear end of the casing, a switch is arranged on the handle, a handle is arranged on the casing near the saw blade, a group of limit blocks are arranged on both sides of the casing, a sliding rod is slidably penetrated on each group of limit blocks, and a baffle is commonly connected to the front ends of the two groups of sliding rods.

[0007] The working principle of the above technical solution is as follows:

[0008] When the present invention is in use, the baffle is pushed to a suitable position according to the diameter of the cut wood, which can more effectively prevent wood chips from splashing and better protect the hands and body parts of the operator.

[0009] In a further technical solution, a push handle is provided on the slide rod.

[0010] In a further technical solution, the baffle is a curved plate bent toward the saw blade, which can rebound the flying wood chips toward the saw blade. Compared with the design of the baffle bent toward the hand in the prior art, the baffle of the same height can achieve a larger blocking angle.

[0011] In a further technical solution, the number of the limit blocks in each group is 2, and the push handle is located between two limit blocks.

[0012] In a further technical solution, the driving motor of the saw blade is a circuit board motor.

[0013] In a further technical solution, the circuit board motor includes a circuit board, a rotor and a rotating shaft, the circuit board is provided with a winding coil, and the circuit board is a PCB printed circuit board; a magnet is provided on the rotor, the rotor and the circuit board are arranged relative to each other, and the rotor is fixedly connected to the rotating shaft.

[0014] The beneficial effects of the present invention are:

[0015] 1. When the present invention is in use, according to the diameter of the wood being cut, the baffle is pushed to a suitable position, which can more effectively prevent wood chips from splashing and better protect the hands and body parts of the operator;

[0016] 2. The baffle plate of the present invention is designed as a curved plate that bends toward the saw blade, so that the flying wood chips can be rebounded toward the direction of the saw blade. Compared with the design of the baffle plate bending toward the hand in the prior art, the baffle plate of the same height can achieve a larger blocking angle;

[0017] 3. The present invention adopts a circuit board motor as the driving motor of the saw blade and a PCB printed circuit board as the motor stator. The overall structure is compact, the volume is small, the weight is light, the speed range is large, and it has higher portability, which can further improve the working efficiency of the electric saw.
