Embodiment approach 1

[0033] A kind of double saw blade reciprocating saw of the present invention such as Figures 1 to 9 As shown, it includes a plastic housing 1, the housing includes a first housing 2.1 and a second housing 2.2, the rear part 2.3 of the housing 1 is set as a hand-held part 2.4 and a positioning wire barrel 2 for the cable to move out , the switch button 3 for the user to turn on the power. The first reciprocating rod 5 and the second reciprocating rod 6 arranged in a vertical distribution, and the guide rail 33 sleeved in the first reciprocating rod and the second reciprocating rod, preferably, the guide rails in this embodiment are set to two, respectively The front guide rail 34, the rear guide rail 35, the front guide rail and the rear guide rail respectively cover the first reciprocating rod and the second reciprocating rod before and after. The motor 4 and the transmission mechanism 7 arranged in the housing, the saw blade clamping mechanism 8 arranged at the front end 2....

Embodiment approach 2

[0039] Such as Figure 10 , 11 As shown, the second embodiment is basically the same as the first embodiment, the difference is that the transmission mechanism 7 in this embodiment includes a bracket 100 arranged at an oblique angle, the main shaft 101 arranged on the bracket is arranged on the The bevel gear 102 on the main shaft is arranged on the double eccentric wheel 103 on the said bevel gear, and the said double eccentric wheel 103 comprises an upper eccentric wheel 104 and a lower eccentric wheel 105 arranged symmetrically with respect to said main shaft, and the bevel gear is provided with a shaft Hole 111, a first eccentric hole 112 is opened on the upper eccentric wheel, a second eccentric hole 113 is opened on the lower eccentric wheel, and the main shaft passes through the shaft hole, the first eccentric hole and the second eccentric hole in sequence. The upper eccentric wheel and the lower eccentric wheel are fixed to each other, the upper eccentric wheel 104 is...

Abstract

The invention discloses a double-saw-blade reciprocating saw. The double-saw-blade reciprocating saw comprises a shell, a first reciprocating rod, a second reciprocating rod, guide rails, a motor, a transmission mechanism and a saw blade clamping mechanism. The first reciprocating rod and the second reciprocating rod are distributed up and down; the guide rails are sleeved with the first reciprocating rod and the second reciprocating rod; the motor, the transmission mechanism and the saw blade clamping mechanism are arranged in the shell; the motor is arranged on the upper portion or the lower portion of the transmission mechanism and provides a power source for the transmission mechanism; the transmission mechanism drives the first reciprocating rod and the second reciprocating rod to do linear reciprocating motion; and the front end of the first reciprocating rod and the front end of the second reciprocating rod are connected with a first saw blade and a second saw blade respectively, and the first saw blade and the second saw blade are arranged on the saw blade clamping mechanism. The overall length of the double-saw-blade reciprocating saw is reduced, and therefore the double-saw-blade reciprocating saw is suitable for being operated and used in narrow and small space and also suitable for single-hand operation; and the saw blade clamping mechanism is used for positioning a gap between the two saw blades, and the effect of preventing the two saw blades from deviating is achieved.

Description

technical field [0001] The invention relates to a cutting device, in particular to a reciprocating saw with double saw blades. Background technique [0002] Similar double-blade reciprocating saws in the prior art have been disclosed by the following patent documents. [0003] Chinese Utility Model Patent Specification CN201220450374.X (published on March 27, 2013) discloses a double-saw reciprocating saw, which is mainly that the motor in the double-saw reciprocating saw can simultaneously drag two eccentric wheels, and drive two Two reciprocating rods make symmetrical reciprocating motions, so that the two saw blades always move in opposite directions, so that the double-saw reciprocating saw can bear two opposite forces at the same time, so that the resultant force of the double-saw reciprocating saw is almost Therefore, the vibration and recoil caused by reciprocating motion are effectively eliminated, the comfort of the operator is effectively guaranteed, and the inten...
