Further, two groups of rubber bushs and metal sleeve are separately fixed on the bent axle of driving gear crank and driven gear crank by circlip for shaft.
Wherein, described slide block is hollow structure, the bent axle of driving gear crank and driven gear crank is inserted in the hollow open of slide block, motor drives the rotation of driving gear crank by rotating shaft, driving gear crank drives the rotation of driven gear crank by gear pair, pumps thereby promote slide block.
Wherein, described framework comprises housing, lower housing and stop sleeve, and upper housing, lower housing and two stop sleevees link together by two groups of bolt groups.
Further, also comprise energy-storaging spring, its one end is connected with upper housing or lower housing, and the other end is connected with housing of electric tool.
Further, described damping device is yielding rubber or damping spring.
Further, in stop sleeve one side, adjustment pad is set, adjusts pad and can regulate the pretightening force of damping device by increase and decrease.
Further, upper housing or lower housing are connected with processing device.
The advantages such as the beneficial effects of the utility model are, the rigid impulse of load in reciprocating electric tool processing is become to soft impulse by damping device, and it is less that this transmission device has vibrations compared with existing structure, and longer service life, machining locus are better.

Embodiment
Below in conjunction with accompanying drawing, the utility model is specifically described.
As Figure 1-4, upper housing 1, lower housing 8 and two stop sleevees 5 link together by two groups of bolt groups 3, two guide rods 2 are fixedly connected on housing 1, lower housing 8, slide block 6 is arranged between housing 1 and lower housing 8, slide block 6 can slide up and down along guide rod 2, between slide block 6 and upper housing 1 and lower housing 8, be provided with buffer unit 4, thereby slide block 6 and upper housing 1, lower housing 8 are combined into an entirety.Damping device can be yielding rubber or damping spring.
Two groups of rubber bushs 13 and metal sleeve 12 are separately fixed on the bent axle of driving gear crank 9 and driven gear crank 10 by circlip for shaft 14.Driving gear crank 9 and driven gear crank 10 form slidercrank mechanism with slide block 6, slide block 6 is hollow structure, the bent axle of driving gear crank 9 and driven gear crank 10 is inserted in the hollow open of slide block, and upper housing 1 or lower housing 8 are connected with processing device 11.
When work, motor drives driving gear crank 9 to rotate by the rotating shaft of driving gear crank 9, drive driven gear crank 10 to rotate by gear pair, the bent axle of driving gear crank 9 and driven gear crank 10 horizontally slips in slide block, thereby promoting slide block 6 pumps, slide block 6 drives upper housing 1, lower housing 8 to move by yielding rubber or damping spring 4, finally drives processing device 11 to pump.
Can arrange and adjust pad 7 in stop sleeve 5 one sides, adjust pad 7 and can regulate the pretightening force of yielding rubber 4 by increase and decrease.
On upper housing or lower housing 8, can also connect an energy-storaging spring, the other end of energy-storaging spring is connected with housing of electric tool.Move downward and be processed as example with processing device 11, upper housing 1, lower housing 8 move downward compress energy storage spring and store energy, move upward to unclamp energy-storaging spring and release energy.
