Abstract
The present invention relates to a kind of dust-proof perching knife, including blade, knife rest and support bar, described blade is fixed on the upper end of knife rest, it is characterised in that: the lower end of described knife rest is provided with connecting portion, and described support bar is movably connected with connecting portion, described support bar is provided with one and connects seat, being connected with an adjusting rod connecting on seat, described adjusting rod can rotate around connecting seat, is provided with locking nut at its connecting place, the tail end of described adjusting rod is provided with a lasso, and described lasso is provided with dust bag.After using said structure, knife rest can so facilitate blade to fit with metope in the rotation of 360 degree of the top of support bar；Also being connected with a dust bag on described support bar, in use, the coating shoveled can drop in dust bag, thus avoids the coating dropped to pollute surrounding or room air, reduces the dust actual bodily harm to workmen.
Description
Technical field
The present invention relates to a kind of construction and decoration instrument, a kind of dust-proof perching knife for removing wall covering.
Background technology
In life, some old houses are when finishing to be re-started, it is often necessary to first on metope coating (such as:
Powder of lacquer putty for use on) carry out large-area rooting out process, carry out construction in later period the most again.Existing perching knife, when rooting out dope layer, is all
Allow dope layer directly drop on ground, the most easily pollute environment, and overhead have a segment distance due to dope layer,
Can produce a lot of dust during dropping, these dust can descend slowly and lightly on health, or enters the internal of constructor along with breathing,
Badly influence the healthy of workman.
Disclosing a kind of perching knife in Chinese patent CN104563453A, including blade, knife rest and handle, described blade can
Releasably being inserted in cracking of described knife rest interior, described knife rest is connected in hinged way with described handle, and described handle is scalable
Structure, knife rest is provided with coating material recovery bath.Thus can change the direction of blade, the convenient metope to various location is carried out
Strike off, but it can only change vertical direction, it is impossible to change the level angle of blade；It addition, coating material recovery bath can be to dropping down
The coating come reclaims, and prevents coating from falling on health, but does not also reach the purpose preventing dust recycling.
Summary of the invention
For the deficiencies in the prior art, it is an object of the invention to provide a kind of dust-proof perching knife, the coating not only can will rooted out
Collect, prevent its contaminated air and environment, and the angle of knife rest can regulate, convenient use.
For reaching above-mentioned purpose, the present invention adopts the following technical scheme that
A kind of dust-proof perching knife, including blade, knife rest and support bar, described blade is fixed on the upper end of knife rest, it is characterised in that: institute
The lower end stating knife rest is provided with connecting portion, and described support bar is movably connected with connecting portion, and described support bar is provided with one and connects seat,
Being connected with an adjusting rod connecting on seat, described adjusting rod can rotate around connecting seat, is provided with locking screw at its connecting place
Mother, the tail end of described adjusting rod is provided with a lasso, and described lasso is provided with dust bag.
Preferably, the tail end of described support bar is provided with a hand-pushing handle.
Preferably, described connecting portion is the sleeve of a hollow, and described sleeve is equipped with the top of support bar, at set
It is provided with a circle annular slot in Tong, now, is provided with the elastic force pearl of projection in the side, top of support bar, packs into sleeve at support bar
Time interior, elastic force pearl can just be fastened in annular slot.
Preferably, described dust bag mouth is provided with the protective jacket of a taper.
After the invention have the advantage that the structure of the employing present invention, knife rest can be in the rotation of 360 degree of the top of support bar, this
Sample, when rooting out dope layer, facilitates blade to fit tightly with metope；Also it is connected with a dust bag on described support bar, is using
Time, the coating shoveled can drop in dust bag, thus avoids the coating dropped to pollute surrounding or room air, reduces
The dust actual bodily harm to workmen.
Accompanying drawing explanation
The present invention will be further described with detailed description of the invention below in conjunction with the accompanying drawings.
Fig. 1 is the structural representation of a kind of dust-proof perching knife of the present invention；
Fig. 2 is A-A ＇ sectional view in Fig. 1；
In figure: 1, blade；2, knife rest；3, support bar；4, connecting portion；5, seat is connected；6, adjusting rod；7, locking nut；8, lasso；
9, dust bag；10, hand-pushing handle；11, annular slot；12, elastic force pearl；13, protective jacket.
Detailed description of the invention
Before describing the embodiments in more detail, it should be understood that the invention is not restricted in the application hereafter or institute in accompanying drawing
The detailed construction described or arrangement of elements.The present invention can be the embodiment that alternate manner realizes.Furthermore, it is to be understood that this paper institute
The wording used and term are solely for describing purposes, should being construed as limiting property not explain.
As shown in Figure 1: a kind of dust-proof perching knife, including blade 1, knife rest 2 and support bar 3, described blade 1 is fixed on knife rest 2
Upper end, the lower end of described knife rest 2 is provided with connecting portion 4, and described connecting portion 4 is the sleeve of a hollow, and the size of sleeve is just
Can guarantee that the top of support bar 3 can pack into；Now, as in figure 2 it is shown, be provided with a circle annular slot 11 in sleeve, and propping up
The side, top of strut 3 is provided with the elastic force pearl 12 of projection, and when support bar 3 packs in sleeve, elastic force pearl 12 can just be fastened on
In annular slot 11, such knife rest 2 just in the rotation of 360 degree of the top of support bar 3, thus can facilitate it to make with metope laminating
With.Described support bar 3 is provided with one and connects seat 5, is connected with an adjusting rod 6 connecting, sets at its connecting place on seat 5
Having locking nut 7, the tail end of described adjusting rod 6 to be provided with a lasso 8, described lasso 8 is provided with dust bag 9, it should be understood that
It is that by the support of adjusting rod 6, described dust bag 9 can just be fixed on the lower end position of knife rest 2, and such blade 1 shovels
Dope layer, when dropping, will fall in dust bag 9, prevents it from dropping on ground or flying away in air, contaminated air and ring
Border.
In fig. 1 and 2, described support bar 3 is arranged to Collapsible structure, so convenient its length of regulation；At support bar 3
Tail end be provided with hand-pushing handle 10, when holding hand-pushing handle 10, the convenient support bar 3 that promotes the most forward, so convenient exert oneself when using.
In the present embodiment, 9 mouthfuls of described dust bag is provided with the protective jacket 13 of a taper, and the coating dropped can be from protective jacket
Leak down in the centre of 13.
During use, turning initially to adjusting rod 6, make dust bag 9 be positioned at the lower end position of knife rest 2, then will be adjusted by locking nut 7
Pole 6 is locked, and thus can hold support bar 3, is fitted on dope layer to be rooted out by blade 1, owing to knife rest 2 can be with 360
Degree rotates, and blade 1 so can be allowed tightr with what metope was fitted；Finally, by promoting hand-pushing handle 10 that dope layer is carried out
Thoroughly rooting out, when shovel is dynamic, the coating powder dropped just can be caught by dust bag 9, thus prevent it from dropping to ground or flying away
In air, pollute.When feeling that dust bag 9 is filled, as long as it is the most repeatable all to pour the garbage of the inside into refuse receptacle
Use.
The present invention is illustrated by above-described embodiment, but it is to be understood that, above-described embodiment is only intended to
Citing and descriptive purpose, and be not intended to limit the invention in described scope of embodiments.In addition people in the art
