Problems solved by technology
[0005] However, due to the small space inside the chainsaw, the debris generated during the operation of the chainsaw will be brought into the gap between the saw blade, the back plate and the splint under the action of the saw blade, and will accumulate in it and cannot be discharged, resulting in two A saw blade is squeezed and dislocated, which affects the cutting effect; at the same time, it leads to difficulty in driving the motor, increased power consumption, and heat of the saw blade until the saw blade cannot move, which affects the service life of the motor.

Embodiment Construction
[0016] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.
[0017] like Figure 1 to Figure 6 Shown, the chainsaw with dual saw blades includes:
[0018] The first saw blade 1, the tail of the first saw blade is connected to the first driving mechanism (not shown in the figure) of the electric saw, and the structure of the first saw blade is a conventional saw blade structure. The side of the first saw blade is welded with a back plate 4, the thickness of the back plate 4 is slightly greater than the thickness of the second saw blade 3, the thickness of the back plate is designed not to hinder the second saw blade 3 between the first saw blade and the splint 2 Under the premise of moving in the gap between them, the smaller the better.
[0019] The splint 2 is parallel to the first saw blade and welded on the back plate 4, so that the back plate 4 is sandwiched between the first saw blade 1 and the s...

The invention relates to a double saw blade for an electric saw. The double saw blade comprises a first saw blade body, a second saw blade body, a clamping plate and a back plate. The first saw blade body and the second saw blade body are used for being connected with a first driving mechanism and a second driving mechanism of the electric saw respectively; the first saw blade body and the clamping plate are connected to the back plate; and a containing groove used for containing the second saw blade body is formed between the clamping plate and the first saw blade body after the first saw blade body, the back plate and the clamping plate are connected. The double saw blade for the electric saw is characterized in that saw teeth are also arranged on the back face of the second saw blade body. Compared with the prior art, the saw teeth are also designed on the back face of the second saw blade body so that wood bits brought into the containing groove when the double saw blade works can be discharged in time, the cutting precision and the cutting efficiency of the double saw blade can be ensured, and the problems that cutting is in disorder and power consumption is increased due to saw blade dislocation caused by wood bit extruding and plugging in the prior art can be solved.
Description
technical field [0001] The invention relates to a double saw blade for an electric saw. Background technique [0002] The double-blade chainsaw is popular because it can work conveniently without supporting the workpiece to be cut when it is used, and the cutting action is smooth and the operation is labor-saving. The existing double saw blade structure usually includes a first saw blade and a second saw blade arranged parallel to each other, and the first saw blade and the second saw blade are arranged in the slot of the guide sleeve. To maintain the opposite movement of the two saw blades, it is necessary to have a certain fit gap between the two, and a certain gap must also be maintained between the two saw blades and the slot to facilitate the reciprocating movement of the two saw blades, so the The width of the slot in the guide sleeve is greater than the sum of the thicknesses of the two saw blades. The guide sleeve is arranged on the main body of the electric saw, t...
