On be provided with lock tooth, relative tooth of locking is provided with locking projections on the outer surface of another knife rest, and the locking projections, which fix, to exist
Locking is realized in the lock tooth.
Further, the lock tooth set in the elongated portion is along the multiple of pipe cutting circumferential array to be cut.
Further, the end set of the elongated portion has the handgrip being upturned.
To sum up content, a kind of pipe cutter described in the utility model is not only simple in construction and easy to operate, as long as will
Knife rest is clamped in the outside cutting for revolving the i.e. achievable pipe that turns around of pipe cutting to be cut, can greatly improve cutting efficiency, and can be significantly
The quality of otch is improved, otch specification impulse- free robustness, the proportion of goods damageds and useless pipe rate can all reduce.
Brief description of the drawings
Fig. 1 is the utility model pipe cutter structural representation;
Fig. 2 is structural representation of the utility model pipe cutter under clamp position.
As depicted in figs. 1 and 2, knife rest 1, cutter 2, latch-up structure 3, elongated portion 3a lock tooth 3b, locking projections 3c, and hand is grabbed
Portion 3d, handle 4, rotating shaft 5, cover plate 6, through hole 7, positioning convex 8.
Embodiment
The utility model is described in further detail with embodiment below in conjunction with the accompanying drawings:
As depicted in figs. 1 and 2, a kind of pipe cutter, for cut be connected with new blower fan, dehumidifier, indoor apparatus of air conditioner it is new
Airduct.Including two semicircle knife rests 1, it is rotatably connected together by rotating shaft 5 between two knife rests 1, two knife rests 1 fasten
Through hole 7 is formed afterwards, and fresh wind tube (not shown) to be cut is installed through the through hole 7 when needing cutting, utilized
Fresh wind tube to be cut is clamped in centre by two knife rests 1.
Cutter 2 is installed on knife rest 1, cutter 2 is passed from knife rest 1 and stretched out to the axis direction of through hole 7, i.e., in
Between fresh wind tube direction stretch out, cut through the tube wall of fresh wind tube in cutting.It is provided with least one of which knife rest 1 for hand
The handle 4 of gripping, operating personnel, which hold with a hand handle 4, can complete the cutting of fresh wind tube, not only facilitate operating personnel to operate, together
When also ensure operating personnel's working security, it is safe and reliable.
In order to ensure cutter 2 in cutting can fixation, in the present embodiment, one is set in handle 4 in flat
Cutter groove (not shown), cutter 2 are arranged in cutter groove, have opening on the wall of knife rest 1 of cutter groove side, and cutter 2 is from opening
In pass and stretch in through hole 7, this structure can ensure that cutter 2 does not produce in cutting and rock, and effectively avoid repeating to cut
The phenomenon cut, make otch specification smooth, and then ensure cut quality.The length that wherein cutter 2 stretches out can be open by limiting
Size limit, can also be limited by setting position limiting structure between cutter groove and the cutter 2.In the present embodiment, in cutter groove 2
On also set up a dismountable cover plate 6, cover plate 6 is fixedly connected by structures such as screw or buckles with handle 4, for being convenient for changing
Cutter 2.
At least one positioning convex 8 is provided with the inner surface of knife rest 1, positioning convex 8 is used to act against in clamping
On the outer surface of fresh wind tube, in the present embodiment, positioning convex 8 is two or three preferably along the circumferentially disposed of fresh wind tube, to protect
The fresh wind tube to be cut stable fixation in cutting is demonstrate,proved, and then ensures cut quality.Two or three positioning convex 8 can be set
In the same circumferential discontinuity of knife rest 1, cutter 2 is arranged on the side of positioning convex 8;Can also be in two circumference of knife rest 1
One group of positioning convex 8 is set respectively on section, and every group includes two or three positioning convex 8, and cutter 2 is arranged on two groups of convexes
Rise between 8.
Because fresh wind tube uses bellows more, in the present embodiment, more preferably positioning convex 8 along the ripple of bellows using walking
To extended structure, when clamping bellows, two or three positioning convex 8 in same circumferential discontinuity are embedded in simultaneously
In the groove of bellows, this way it is possible to avoid bellows to be cut moves radially, while bellows can also be avoided along axle
To movement, ensure stability during cutting, effectively avoid repeating the phenomenon cut, make otch specification smooth, and then ensure cutting
Quality.
Two knife rests 1 are locked after fastening by latch-up structure 3.Latch-up structure 3 is included from the end of a knife rest 1 to overhanging
The elongated portion 3a gone out, is provided with lock tooth 3b on elongated portion 3a, locks tooth 3b relatively and is provided with the outer surface of another knife rest 1
Locking projections 3c, locking projections 3c fix realizes locking in lock tooth 3b.In the present embodiment, it is preferably provided on elongated portion 3a
It is to adjust locking projections according to the caliber of fresh wind tube to be cut along the multiple of fresh wind tube circumferential array, operating personnel to lock tooth 3b
The lock tooth 3b fixed needed for 3c position, makes the device go for the cutting of the fresh wind tube of different tube diameters, versatility is able to
Improve.
The handgrip 3d being upturned is additionally provided with elongated portion 3a end, facilitates operating personnel's hand to catch handgrip 3d
Realize the unblock or locking of two knife rests 1.
The cutting process of the pipe cutter is described below in detail:
1st, two knife rests 1 are enclosed on fresh air bellows to be cut first, and mutually fastened.
2nd, the lock tooth 3b on the extension 3a of side and the locking projections 3c on another outer surface of knife rest 1 are connected and fixed,
Bellows is clamped in the through hole 7 surrounded by two knife rests 1, and now, positioning convex 8 is embedded in the groove of bellows real
Now position.
3rd, for two knife rests 1 while snap lock, cutter 2 cuts through the tube wall of bellows, and one hand of operating personnel is held
Fresh wind tube, another hand are held the handle 4 of pipe cutter, rotated a circle along the direction where blade, and cutter 2 can cut bellows
It is disconnected.
4th, operating personnel hold handgrip 3d, and elongated portion 3a is lifted up, and make locking projections 3c from lock tooth 3b
Abjection, two knife rests 1 separate, and take out the fresh wind tube after cutting.
The pipe cutter is simple in construction, easy to operate, as long as knife rest 1 to be clamped in the outside of fresh wind tube to be cut and rotation
The cutting of fresh wind tube can be achieved in one circle, can not only greatly improve cutting efficiency, can also greatly improve the quality of otch, the proportion of goods damageds
It can all be reduced with useless pipe rate, otch specification impulse- free robustness, the fitness of the pipe fitting with needing to connect improves, it is ensured that the sealing of pipeline
Can, effectively avoid falling off during Pipe installing, the problem of leaking out.
As described above, the plan content with reference to given by accompanying drawing, can derive similar technical scheme.In every case it is not de-
From the content of technical solutions of the utility model, above example is made according to the technical essence of the utility model any simple
Modification, equivalent variations and modification, in the range of still falling within technical solutions of the utility model.
