Description

Casing knife

Technical field

The utility model relates to a kind of flexible pipe cutting device, has related in particular to a kind of casing knife.

Background technology

At present, the shearing of flexible pipe completes with casing knife, as patent 200820118720.8 disclose a kind of for shearing the device of flexible pipe, but when the blade in this device because repeatedly shear when passivation, cause for this reason blade can not be removed polishing, and casing knife apparatus can only be discarded by entirety. In the time not using pipe cutter, this pipe cutter may be owing to dropping and accidentally injuring people from eminence, and in use, user must carry measurer to realize the measuring of pipe shearing length to this pipe cutter simultaneously, very inconvenient simultaneously.

Summary of the invention

The utility model, for above-mentioned shortcoming, provides a kind of casing knife.

In order to solve the problems of the technologies described above, the utility model is solved by following technical proposals:

Casing knife, comprises knife rest and is hinged on the tool rest on knife rest, the head of knife rest is provided with blade, and tool rest is provided with cutter groove, and described blade is regular polygon. The blade that is regular polygon has multiple nose angles for cutting, and when a cutter pin is used for a long time and when passivation, only needs the more setting angle of allowing blade replacement, cuts and cuts flexible pipe with original nose angle.

As preferably, blade is regular hexagon. Regular hexagon contains six nose angles, and be six times of blade that only contain single nose angle the normal service time of this blade.

As preferably, knife rest comprises left halfbody and right halfbody, between left halfbody and right halfbody, is screwed connection, and blade is between left halfbody and right halfbody, and blade is provided with through hole, and described screw is through the through hole on blade. When needs are more when tool changing pin, only need turn on screw, blade is taken out between left halfbody and right halfbody, after the angle of adjustable blade, put into, again tighten the screws.

As preferably, knife rest is provided with snap close, and snap close is provided with limited block, and tool rest is provided with stopper slot, and limited block stretches in stopper slot. In the time not using this casing knife, can use snap close to pin this casing knife, knife rest and tool rest can not open, and prevent that blade from surprisingly hurting sb.'s feelings.

As preferably, snap close comprises slider and the extension bar perpendicular to slider, and slider is positioned at knife rest outside, extends bar and stretches in knife rest, extends bar and is provided with extension stick, extends stick and contacts with knife rest madial wall, and slider can slide above knife rest outer surface. When closed between knife rest and tool rest, while promoting slider to knife rest head movement, limited block stretches in stopper slot, between knife rest and tool rest, can not again open, and therefore promotes the state that slider motion can realize snap close and switches, simple in structure, practical.

As preferably, in knife rest, be provided with tape measure, the chi hook of tape measure stretches out from the afterbody of knife rest. The length that the tape measure person of being easy to use measures the required flexible pipe cutting is set.

The utility model has adopted technique scheme, can greatly extend the service time of blade, and casing knife can just not gone out of use because of single nose angle passivation, again can person easy to use measures the length of flexible pipe, is also provided with locker and prevents that blade from surprisingly hurting sb.'s feelings.

Detailed description of the invention

Below in conjunction with accompanying drawing and embodiment, the utility model is described in further detail.

Embodiment 1

Casing knife, as shown in Figure 1 to Figure 3, comprises knife rest 1 and is hinged on the tool rest 3 on knife rest 1, the head of knife rest 1 is provided with blade 2, is provided with built-in tape measure 5 in knife rest 1, and tool rest 3 is provided with cutter groove 302, and described blade 2 is regular hexagon, as shown in Figure 6.

Knife rest 1 comprises left halfbody 101 and right halfbody 102, between left halfbody 101 and right halfbody 102, is screwed connection, and blade 2 is between left halfbody 101 and right halfbody 102, and blade 2 is provided with through hole 201, and described screw is through the through hole 201 on blade 2.

Knife rest 1 is provided with snap close 4, and as shown in Figure 4, snap close 4 is provided with limited block 401, and tool rest 3 is provided with stopper slot 301, and limited block 401 stretches in stopper slot 301. Snap close 4 comprises slider 404 and the extension bar 403 perpendicular to slider 404, slider 404 is positioned at knife rest 1 outside, extending bar 403 stretches in knife rest 1, extend bar 403 and be provided with extension stick 402, extending stick 402 contacts with knife rest 1 madial wall, slider 404 can slide and can not come off on knife rest 1 outer surface, as shown in Figure 5.

Embodiment 2

Identical with embodiment 1, difference is that blade is regular pentagon, as shown in Figure 7.
