Description

A kind of fool proof reciprocating saw
Technical field
The present invention relates to field of power tools, and in particular to a kind of reciprocating saw.
Background technology
Reciprocating saw is the most-often used electric tool of people, and that it has the advantages that is convenient, inexpensive, is easy to carry, and depth is by five The favorable comment of worker in gold, decoration industry.But operator is frequently necessary to change saw blade when using reciprocating saw, because the side of seeking Just, operator is directly to change saw blade in the case where reciprocating saw does not power off, if oneself or other people when changing saw blade Switch has been touched by mistake and has caused saw blade motion, is extremely dangerous.
The content of the invention
For the deficiencies in the prior art, the present invention provides a kind of reciprocating saw, can not in the case of reciprocating saw energization Change saw blade.
The present invention is achieved through the following technical solutions:A kind of fool proof reciprocating saw, including saw body and saw blade, institute State saw blade to be driven by reciprocating lever, described reciprocating lever one end is provided with the fixing device for being used for fixing saw blade, and the fixing device includes First sleeve and second sleeve, the second sleeve are set on the first sleeve, are set between first sleeve and second sleeve There is torsion spring, first sleeve is provided with saw blade fixing groove, and the both ends of the saw blade fixing groove are provided with ball base, the ball base It is interior to be provided with ball, the groove with ball engagement is provided with the second sleeve, when saw blade inserts saw blade fixing groove, the ball Ball base is stuck in by groove so that saw blade is fixed in fixing groove, rotating second sleeve makes ball depart from ball base, and saw blade is consolidated Determine status releasing, the groove is provided with electromagnet base, is provided with electromagnet in the electromagnet base, first sleeve is provided with Block groove, the block groove is interior to be provided with block, and the block is made of magnetic material, is provided between block and the block groove Back-moving spring, when electric saw is powered, the electromagnet holds block so that ball can not depart from ball base.
Further, the second sleeve is provided with antiskid thread.
Compared with prior art, for the present invention in the case of energization, electromagnet holds block, block when rotating the first sleeve Ball is blocked so that ball can not depart from ball base, operator can not just change saw blade, and they can only power off to reciprocating saw, at this moment The magnetic force of electromagnet is disappeared, and block is returned in the presence of back-moving spring in block groove, and operator can change saw blade, above-mentioned knot Structure effectively prevents operator from changing saw blade in the case where reciprocating saw is powered, and avoids causing danger.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention.
Fig. 2 is the structural representation of saw blade clamping of the present invention.
Fig. 3 is the structural representation of fixing device of the present invention.
Fig. 4 is another structural representation of fixing device of the present invention.
Embodiment
The present invention is described in further detail with embodiment below in conjunction with the accompanying drawings.It is a kind of referring to Fig. 1 to Fig. 4 Fool proof reciprocating saw, including saw body 1 and saw blade 2, the saw blade 2 are driven by reciprocating lever 3, and described one end of reciprocating lever 3 is provided with For fixing the fixing device 4 of saw blade 2, the fixing device 4 includes the first sleeve 41 and second sleeve 42, the second sleeve 42 are set on the first sleeve 41, are provided with torsion spring between first sleeve 41 and second sleeve 42, on first sleeve 41 Provided with saw blade fixing groove, the both ends of the saw blade fixing groove are provided with ball base 5, are provided with ball 51 in the ball base 5, and described the The groove 421 coordinated with ball 51 is provided with two sleeves 42, when saw blade 2 inserts saw blade fixing groove, the ball 51 is by groove 421 are stuck in ball base 5 so that saw blade 2 is fixed in fixing groove, and rotating second sleeve 42 makes ball 51 depart from ball base 5, saw blade 2 Stationary state release, the groove 421 is provided with electromagnet base 6, and the electromagnet base 6 is interior to be provided with electromagnet 61, described the One sleeve 41 is provided with block groove 7, block 71 is provided with the block groove 7, the block 71 is made of magnetic material, described Back-moving spring 72 is provided between block 71 and block groove 7, when electric saw is powered, the electromagnet 61 holds block 71 and causes ball 51 can not depart from ball base 5.
The second sleeve 42 is provided with antiskid thread.
For the present invention in the case of energization, electromagnet holds block, and block blocks ball so that rolling when rotating the first sleeve Pearl can not depart from ball base, and operator can not just change saw blade, and they can only power off to reciprocating saw, and at this moment the magnetic force of electromagnet disappears Lose, block is returned in the presence of back-moving spring in block groove, and operator can change saw blade, and said structure effectively prevents from grasping Author changes saw blade in the case where reciprocating saw is powered, and avoids causing danger.
