The utility model discloses a reciprocating saw that aims at passes through pinion rotation by electric motor, drives the gear wheel and rotates, and the eccentric round pin of gear wheel drives the reciprocating lever and is reciprocating motion. No matter what transmission mode is adopted, the reciprocating motion of the reciprocating rod is required to drive the saw blade to do reciprocating saw cutting motion. When the reciprocating rod does reciprocating motion, the supporting block is required to support the reciprocating rod to do reciprocating motion. However, in the prior art, because the supporting block is in direct contact with the reciprocating rod, after the electric reciprocating saw is started, the supporting block continuously rubs against the reciprocating rod back and forth, so that the supporting block and the reciprocating rod generate heat, a moving part is quickly abraded, and a reduction box in the electric reciprocating saw generates heat. Long-time use can lead to the reducing gear box to generate heat seriously, and the reducing gear box sealing member can be because of high temperature rapid melting, and the damage of sealing member will lead to inside external iron fillings dust etc. get into the reducing gear box, destroys reciprocating saw inner structure, makes reciprocating saw life-span shorten.

In order to solve the problem, the utility model adopts the technical scheme that an independent lubricating device of reciprocating saw is provided, its characterized in that: comprises a reciprocating rod, a supporting block, an oil storage tank and an oil hole; the reciprocating saw is internally provided with a front supporting block and a rear supporting block, through holes are formed in the supporting blocks, and the reciprocating rod penetrates through the through holes of the front supporting block and the rear supporting block; the upper end surface of the supporting block parallel to the through hole is provided with an oil hole which is communicated with the through hole penetrating the reciprocating rod; the upper end surface of the supporting block is provided with an oil storage tank.
Preferably, the bottom of the oil storage tank is the upper end surface of the supporting block, and the side wall and the upper cover of the oil storage tank are structural members integrally formed with the housing of the reciprocating saw.
Preferably, the reciprocating saw shell corresponding to the oil storage tank is provided with an oil filling hole of the oil storage tank.
Preferably, the number of the supporting blocks is more than or equal to 2.
Preferably, the number of the oil holes formed in the upper end surface of the supporting block is greater than or equal to 1.

Detailed Description
In order to make the present invention more comprehensible, preferred embodiments are described in detail below with reference to the accompanying drawings.
As shown in fig. 1 and 2, the reciprocating saw of the present invention is adapted to drive the gear 4 to rotate by the rotation of the electric motor 6 through the pinion 5, and the eccentric pin of the gear 4 drives the reciprocating rod 3 to reciprocate. The utility model provides an independent lubricating device of a reciprocating saw, which comprises a reciprocating rod 3, a supporting block 2, an oil storage tank 7 and an oil hole 8; the reciprocating saw is internally provided with a front supporting block 2 and a rear supporting block 2, a through hole is formed in each supporting block 2, and a reciprocating rod 3 is arranged in the through holes of the front supporting block 2 and the rear supporting block 2 in a penetrating manner; the upper end surface of the supporting block 2 parallel to the through hole is provided with an oil hole 8, and the oil hole 8 is communicated with the through hole through which the reciprocating rod 3 passes; an oil storage tank 7 is arranged on the upper end face of the supporting block 2, the bottom of the oil storage tank 7 is the upper end face of the supporting block 2, and the side wall and the upper cover of the oil storage tank 7 are structural members integrally formed with the reciprocating saw shell 1; the housing 1 of the reciprocating saw is provided with an oil hole of the oil storage tank 7. Grease is added into the oil storage tank 7 through the oil filling hole on the reciprocating saw shell 1, and then the oil filling hole is sealed. When the reciprocating saw works, the reciprocating rod 3 linearly reciprocates, the reciprocating rod 3 rubs with the supporting block 2, the machine vibrates, the temperature in the reciprocating saw is raised, the fluidity of the grease is increased, and the grease flows down from the oil hole 8 at the bottom of the oil storage tank 7.
