Abstract
The invention relates to a saw which comprises an H-shaped saw body with the two sides provided with opening gaps, a first saw blade and a second saw blade, wherein the first saw blade and the second saw blade are arranged in the opening gaps in the two sides. The first saw blade is fixedly connected to the two ends of the opening gap in the corresponding side through connecting seats at the two ends. The second saw blade is connected to the two ends of the opening gap in the corresponding side through connecting seats at the two ends in a sliding manner. The outer sides of the connecting seats at the two ends of the second saw blade are fixedly provided with sliding blocks respectively. Sliding grooves corresponding to the sliding blocks are embedded into the portions, on the second saw blade, of the side wall of the saw body. The portions, corresponding to the sliding grooves and on the second saw blade, of the top face of the saw body are provided with fixing grooves communicated with the sliding grooves. The sliding blocks are fixedly provided with stand columns with threads. The stand columns penetrate the fixing grooves to be in threaded connection fit with fastening nuts. Saw teeth of the first saw blade and saw teeth of the second saw blade are arranged in the manner of facing the outer side of the saw body. By the adoption of the saw, it can be guaranteed that cutting is timely and continuous, and the service life is prolonged.

Technical field
The present invention relates to cutting processing technical field of tools, specifically relate to saw.
Background technology
In current vehicle component processing process; often need to use saw to carry out cutting processing operation; saw in use often there will be breakage phenomenon, but conventional saw is only equipped with single saw blade, can not ensure the continuous of cutting operation in time when single saw blade breaks down.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of being convenient to and ensures that cutting is timely continuously, the saw of long service life.
For solving the problems of the technologies described above, the invention provides following technical scheme: saw, comprise H type saw body, the first saw blade being arranged at both-side opening gap respectively and the second saw blade that both sides offer opened gap, described first saw blade is fixedly connected on the two ends in this side opening gap by the Connection Block at two ends; Described second saw blade is slidably connected to the two ends in this side opening gap by the Connection Block at two ends, slide block is fixed with respectively outside the Connection Block at described second saw blade two ends, this side saw body sidewall is embedded with the chute corresponding with slide block, this side saw body end face corresponds to runner position and offers the holddown groove be connected with chute, described slide block is fixed with threaded column, and described column is threaded through holddown groove and is combined with clamp nut; The sawtooth of described first saw blade and the second saw blade is all towards saw body arranged outside.
Preferential on such scheme basis, also include a protective sleeve, described protective sleeve side is embedded with the holding tank corresponding with the second saw blade, and described protective sleeve two ends are connected in this two ends, side opening gap respectively.
Preferential on such scheme basis, described Connection Block offers standing groove, described Connection Block, the first saw blade and the second saw blade two ends all offer installing hole, and described Connection Block corresponds to position of mounting hole place and is provided with project-welding nut, has fastening bolt to pass installing hole and is matched with project-welding nut.
Preferential on such scheme basis, described saw body is provided with length scale line.
The beneficial effect that the present invention compared with prior art has is: saw provided by the invention, and the first fixing saw blade is established, for daily cutting work in its saw body side; Opposite side establishes slidably the second saw blade; when the first saw blade can normally work; being slided by second saw blade, it is impaired to protect the second saw blade to reduce to move into inside saw body; improve service life; when the first saw blade break down can not work time, the second saw blade is slided and removes to serve as saw blade backup to ensure that cutting is continuous in time.Meanwhile, the second saw blade is convenient to change it by slide block and is stretched into saw body inner distance, and be applicable to some special cutting situation demand, applicability is strong.

Detailed description of the invention
In order to make object of the present invention, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
In describing the invention, it will be appreciated that, term " longitudinal direction ", " transverse direction ", " on ", D score, "front", "rear", "left", "right", " vertically ", " level ", " top ", " end ", " interior ", the orientation of the instruction such as " outward " or position relationship be based on orientation shown in the drawings or position relationship, only the present invention for convenience of description, instead of indicate or imply that the device of indication or element must have specific orientation, with specific azimuth configuration and operation, therefore can not be interpreted as limitation of the present invention.
Known referring to figs. 1 through Fig. 4, saw, comprise both sides to offer the H type saw body 1 of opened gap 2, be arranged at first saw blade 3 and second saw blade 4 in both-side opening gap 2 respectively, described first saw blade 3 is fixedly connected on the two ends in this side opening gap by the Connection Block 5 at two ends; Described second saw blade 4 is slidably connected to the two ends in this side opening gap by the Connection Block 5 at two ends, slide block 6 is fixed with respectively outside the Connection Block at described second saw blade 4 two ends, this side saw body sidewall is embedded with the chute 7 corresponding with slide block 6, this side saw body end face corresponds to runner position and offers the holddown groove 8 be connected with chute, described slide block 6 is fixed with threaded column 9, and described column 9 is threaded through holddown groove 8 and is combined with clamp nut 10; The sawtooth of described first saw blade 3 and the second saw blade 4 is all towards saw body 1 arranged outside.
