Abstract
The invention discloses an anti-misoperation reciprocating saw which comprises a saw body and a saw blade, wherein the saw blade is driven by a reciprocating lever; a fixing device used for fixing the saw blade is arranged at one end of the reciprocating lever; the fixing device comprises a first sleeve and a second sleeve; the second sleeve is arranged on the first sleeve in a sleeving manner; a torsional spring is arranged between the first sleeve and the second sleeve; a saw blade fixing groove is formed in the first sleeve; ball seats are arranged at the two ends of the saw blade fixing groove; balls are arranged in the ball seats; grooves matched with the balls are formed in the second sleeve; an electromagnet seat is arranged on the grooves; an electromagnet is arranged in the electromagnet seat; a stop block groove is formed in the first sleeve; a stop block is arranged in the stop block groove; the stop block is made of a magnetic material; a reset spring is arranged between the stop block and the stop block groove; and when the electric saw is energized, the electromagnet absorbs the stop block, and the balls cannot be separated from the ball seats. According to the anti-misoperation reciprocating saw, the saw blade cannot be changed under the energized situation, so that the danger is effectively avoided.
Description
Technical field
The present invention relates to field of power tools, be specifically related to a kind of reciprocating saw.
Background technology
Reciprocating saw is the electric tool that people the most often use, and it has conveniently, inexpensive, the advantage such as be easy to carry, deeply by the favorable comment of workman in five metals, decoration industry.But operator often needs when using reciprocating saw to change saw blade, because seek conveniently, operator directly changes saw blade when reciprocating saw does not have power-off, if oneself or other people have touched switch and make saw blade move when changing saw blade by mistake, is very dangerous.
Summary of the invention
For the deficiencies in the prior art, the invention provides a kind of reciprocating saw, can not saw blade be changed in reciprocating saw energising situation.
The present invention is achieved through the following technical solutions: a kind of fool proof reciprocating saw, comprise saw body and saw blade, described saw blade is driven by reciprocating lever, described reciprocating lever one end is provided with the fixture for fixing saw blade, described fixture comprises the first sleeve and the second sleeve, described second jacket casing is located on the first sleeve, torsion spring is provided with between described first sleeve and the second sleeve, described first sleeve is provided with saw blade holddown groove, the two ends of described saw blade holddown groove are provided with ball base, ball is provided with in described ball base, the groove with ball engagement is provided with in described second sleeve, when saw blade inserts saw blade holddown groove, described ball is stuck in ball base by groove and makes saw blade be fixed in holddown groove, rotating the second sleeve makes ball depart from ball base, the stationary state of saw blade is removed, described groove is provided with electromagnet base, electromagnet is provided with in described electromagnet base, described first sleeve is provided with block groove, block is provided with in described block groove, described block adopts magnetic material to make, back-moving spring is provided with between described block and block groove, when electric saw is energized, described electromagnet holds block and makes ball to depart from ball base.
Further, described second sleeve is provided with antiskid thread.
Compared with prior art, the present invention is in energising situation, electromagnet holds block, and when rotating the first sleeve, block blocks ball and makes ball to depart from ball base, and operator just cannot change saw blade, they can only give reciprocating saw power-off, at this moment the magnetic force of electromagnet disappears, and block is got back in block groove under the effect of back-moving spring, and operator can change saw blade, said structure effectively prevents operator from changing saw blade when reciprocating saw is energized, and avoids causing danger.

Fig. 2 is the structural representation of saw blade of the present invention clamping.
Fig. 3 is the structural representation of fixture of the present invention.
Fig. 4 is the another kind of structural representation of fixture of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing and detailed description of the invention, the present invention is described in further detail.See Fig. 1 to Fig. 4, a kind of fool proof reciprocating saw, comprise saw body 1 and saw blade 2, described saw blade 2 is driven by reciprocating lever 3, described reciprocating lever 4 one end is provided with the fixture 4 for fixing saw blade 2, described fixture 4 comprises the first sleeve 41 and the second sleeve 42, described second sleeve 42 is set on the first sleeve 41, torsion spring is provided with between described first sleeve 41 and the second sleeve 42, described first sleeve 41 is provided with saw blade holddown groove 411, the two ends of described saw blade holddown groove 411 are provided with ball base 5, ball 51 is provided with in described ball base 5, the groove 421 coordinated with ball 51 is provided with in described second sleeve 42, when saw blade 2 inserts saw blade holddown groove 411, described ball 51 is stuck in ball base 5 by groove 421 and makes saw blade 2 be fixed in holddown groove 411, rotating the second sleeve 42 makes ball 51 depart from ball base 5, the stationary state of saw blade 2 is removed, described groove 421 is provided with electromagnet base 6, electromagnet 61 is provided with in described electromagnet base 6, described first sleeve 42 is provided with block groove 7, block 71 is provided with in described block groove 7, described block 7 adopts magnetic material to make, back-moving spring 72 is provided with between described block 71 and block groove 7, when electric saw is energized, described electromagnet 61 holds block 71 and makes ball 51 cannot depart from ball base 5.
Described second sleeve 42 is provided with antiskid thread.
The present invention is in energising situation, electromagnet holds block, when rotating the first sleeve, block blocks ball and makes ball to depart from ball base, operator just cannot change saw blade, and they can only give reciprocating saw power-off, and at this moment the magnetic force of electromagnet disappears, block is got back in block groove under the effect of back-moving spring, operator can change saw blade, and said structure effectively prevents operator from changing saw blade when reciprocating saw is energized, and avoids causing danger.
