The other end is stretched out outside pedestal, and semicircular hand is installed with the rear side of the pedestal and two sides adjacent with rear side
Handle.The side that pedestal installs balladeur train in the technical program is front side, and relative opposite side is rear side.By installing multiple handles,
When using this electric saw, no matter towards which orientation, can conveniently it grip, it is easy to use.
In above-mentioned hand-held translation electric saw, the joint face of the gear accounts for the half in whole drive wheel circumferences face.Drive
During wheel rotation half, just gear is contacted with the rack engagement in a flat segments, and contacts the tooth in another flat segments
Bar, is achieved in that seamless connection, prevents from skidding, and can realize precisely quick engagement driving every time.
In above-mentioned hand-held translation electric saw, the quantity of the sawtooth has several and uniform intervals are distributed, each saw
Tooth is all obliquely installed, and the sawtooth incline direction in same flat segments is identical, and the sawtooth incline direction in two flat segments is opposite.
This ensure that the smoothness and stability of sawing, it is ensured that electric sawing efficiency.
Compared with prior art, motor can be moved in one direction always in the utility model, pass through rack-and-pinion
Coordinate and drive the movement of sawtooth reciprocating linear, substantially increase movement velocity, and sawtooth is moved back and forth, be not in stuck and beat
Tooth phenomenon.

Embodiment
The following is specific embodiment of the utility model and with reference to accompanying drawing, further is made to the technical solution of the utility model
Description, but the utility model is not limited to these embodiments.
As depicted in figs. 1 and 2, this hand-held translation electric saw includes being installed with motor 2 on pedestal 1, pedestal 1, and hand-held is put down
Moving electric saw also includes the balladeur train 3 of annular, the flat segments 31 of balladeur train 3 including both sides and is put down positioned at the two ends of flat segments 31 and connection two
The segmental arc 32 of straight section 31, one end of balladeur train 3 is slidably connected in pedestal 1 and can moved reciprocating linear on pedestal 1, two
The outside of flat segments 31 is installed with sawtooth 33, and the inner side of two flat segments 31 is installed with rack 34；Between two flat segments 31
Be provided with gear 5 provided with driving wheel 4 and the part-circular periphery face of driving wheel 4, gear 5 can respectively with the rack in two flat segments 31
34 are meshed；Motor 2 is connected with driving wheel 4 by belt 6.In use, motor 2 drives driving wheel 4 to rotate by belt 6, drive
Gear 5 on driving wheel 4 is meshed with the rack 34 in one of flat segments 31, drives the flat segments 31 and whole balladeur train 3
Rectilinear movement, driving wheel 4 is rotated further, and is contacted when the gear 5 on driving wheel 4 is engaged with the rack 34 in a upper flat segments 31,
And when being meshed with the rack 34 in another flat segments 31, the flat segments 31 and whole balladeur train 3 can be driven reverse straight again
Line is moved, so as to realize the reciprocating linear movement of whole balladeur train 3, realizes that straight line sawing is acted by the sawtooth 33 in the outside of balladeur train 3.
Motor 2 can be moved in one direction always in the technical program, alternately and repeatedly moved without positive and negative, substantially increased fortune
Dynamic speed, and sawtooth 33 moves back and forth is not in stuck and beats tooth phenomenon.
The length of flat segments 31 is 3~8 times of the arc length of segmental arc 32 in the present embodiment, preferably 5 times, driving wheel 4 and
The output shaft of motor 2 is respectively positioned on the middle position between two flat segments 31, and the flat segments 31 for so installing sawtooth 33 are enough
Long, balladeur train 3 makes a round trip, and the displacement produced by the sawing of sawtooth 33 is bigger, so that more efficient.
As shown in figure 1, pedestal 1 is in cuboid, the one end of balladeur train 3 is located in pedestal 1, and the other end is stretched out outside pedestal 1, pedestal 1
The side for installing balladeur train 3 is front side, and relative opposite side is rear side, the rear side of pedestal 1 and two sides adjacent with rear side
On be installed with semicircular handle 7, by installing multiple handles 7, when using this electric saw, no matter towards which orientation, all
Can conveniently it grip, it is easy to use.
The joint face of the present embodiment middle gear 5 accounts for the half of the whole periphery of driving wheel 4, when driving wheel 4 rotates half, just
Good gear 5 is contacted with the engagement of rack 34 in a flat segments 31, and contacts the rack 34 in another flat segments 31, so real
Now it is seamlessly connected, prevents from skidding, and precisely quick engagement driving can be realized every time.
As shown in Fig. 2 the quantity of sawtooth 33 has several and uniform intervals are distributed, each sawtooth 33 is obliquely installed, together
The incline direction of sawtooth 33 in one flat segments 31 is identical, and the incline direction of sawtooth 33 in two flat segments 31 is on the contrary, so protect
The smoothness and stability of sawing are demonstrate,proved, it is ensured that electric sawing efficiency.
