Abstract
The utility model relates to a saw, comprising a saw body, an output rotating shaft driven by a power mechanism on the saw body and a cutting part with sawing bits, which is arranged on the output rotating shaft and is driven to rotate by the output rotating shaft; the saw is characterized in that: a screwed hole is arranged on the output rotating shaft, a bolt which penetrates through the cutting part and is connected in the screwed hole of the output rotating shaft in a screwing way is used for connection and fixation between the cutting part and the output rotating shaft. Compared with the prior art, the saw has the advantages that: as the cutting part and the output rotating shaft are fixed and connected by the bolt, when the sawing bit is excessively wore, the whole cutting part is disassembled, the sawing bit is replaced, and the usage is convenient; in addition, a connecting piece with a locating pin is arranged between the cutting part and the output rotating shaft, a locating hole matched with the locating pin is arranged on the output rotating shaft, thereby leading the cutting part and the output rotating shaft to be not easily slipped when the saw is under higher using power, and the usage is more safe.
Description
Technical field
The utility model relates to a kind of saw.
Background technology
Saw is widely used in daily life as a kind of cutting tool, at present most of saw that uses generally comprises the saw body, be arranged on saw on one's body the output revolving shaft that drives by actuating unit and be installed on the output revolving shaft and by its driven rotary the cutting part of band saw blade, but, owing to be generally non-removable fixedly connected between cutting part and the output revolving shaft, and the saw blade on the cutting part is because long-term use wearing and tearing easily, when blade wear excessively can not use, whole saw just can not use.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of output revolving shaft and the removable lining saw of cutting part at above-mentioned prior art.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: a kind of saw, comprise output revolving shaft and be installed on the output revolving shaft and by the cutting part of the band saw blade of its driven rotary, it is characterized in that: described output revolving shaft is provided with screwed hole, runs through described cutting part by one between described cutting part and the described output revolving shaft and the screw that is threaded in the screwed hole of described output revolving shaft is connected and fixed.Like this, when the blade wear on the cutting part excessively need be changed, only screw need be extracted from the screwed hole of output revolving shaft, and be changed new cutting part again, and then with screw new cutting part is fixed on the output revolving shaft and get final product.
Use power at saw causes more greatly under the excessive situation of cutting part torque, cutting part relies on screw to fix easy slippage merely, more firm in order to guarantee to be connected between cutting part and the output revolving shaft, as improvement, be provided with a connection piece between described cutting part and the described output revolving shaft, this connector is provided with the through hole that passes for described screw, and this connector and the contacted position of described output revolving shaft are provided with at least two alignment pins, and are provided with locating hole with the corresponding position of described alignment pin on the described output revolving shaft.By the cooperation of alignment pin and locating hole, even the use power of saw is bigger, also be not easy slippage between cutting part and the output revolving shaft, use safer.
Further improve, described connector and the contacted position of described cutting part also are provided with at least two described alignment pins, and also are provided with locating hole with the corresponding position of described alignment pin on the described cutting part.
Improve again, be provided with a pad between described cutting part and the described screw.
In order to guarantee also to use under the insufficient situation of light, the head of the utility model saw body is provided with illuminating lamp.
Compared with prior art, advantage of the present utility model is: owing to will be connected and fixed by a screw between output revolving shaft and the cutting part,, whole cutting part can be unloaded, change saw blade when blade wear excessively takes, and easy to use.In addition,, the locating hole that cooperates with alignment pin is set on output revolving shaft, makes saw when using power, be not easy slippage between cutting part and the output revolving shaft, use safer than ambassador by between cutting part and output revolving shaft, being provided with the connector that has alignment pin.
