The specific embodiment
In order more clearly to understand above-mentioned purpose of the present invention, feature and advantage, below in conjunction with the drawings and specific embodiments, the present invention is further described in detail.
In description below specifically, a lot of details have been set forth so that fully understand the present invention; but the present invention can also adopt other to be different from other modes described here and realize; therefore, protection scope of the present invention is not subject to the restriction of following public specific embodiment.
It should be noted that, in the situation that not conflicting, the application's implementation column and the feature in embodiment can combine mutually.
As shown in Figure 1, pipe cutting cutter of the present invention, comprises cutter hub 1, handle 2, feeding ratchet 3, ratchet integrated wheel 4, rack blade 5, retaining ratchet 6, torsion spring 7, the first extension spring 8, limit switch 9, the second extension spring 10 and wear-resisting spacing cutting 11.
Described cutter hub 1 comprises upper tool post 101 and lower slide 102, described upper tool post 101 and lower slide 102 are fastened togather, and by fastened by screw, described upper tool post 101 and lower slide card 102 with together with leave afterwards the hole that can make described rack blade 5 stretch out, described cutter hub 1 and handle 2 are combined into rifle formula.
The first end of described handle 2, feeding ratchet 3, ratchet integrated wheel 4 and rack blade 5 are all arranged on described cutter hub 1, the second end of described handle 2 stretches out outside cutter hub 1, and can move forward and backward around the first end of described handle 2 and the contact point of described cutter hub 1, the tooth bar engagement of the tooth bar of described rack blade 5 and described ratchet integrated wheel 4, one side of described handle 2 is connected with described feeding ratchet 3, described handle 2 drives described feeding ratchet 3 pushing away described ratchet integrated wheel 4 rotations, described ratchet integrated wheel 4 drives described rack blade 5 to do one direction rectilinear motion, described rack blade 5 can stretch out outside described cutter hub.Described cutter hub 1 front end arranges pipe rest portion 103, and described rack blade 5 can be to described pipe rest portion 103 displacements.While needing cutting pipe, pipe is shelved on to described pipe rest portion 103, pulls handle 2, by the transmission of feeding ratchet 3, ratchet integrated wheel 4, make rack blade 5 to 103 displacements of pipe rest portion, target pipe is cut.
Described retaining ratchet 6 is arranged on described cutter hub 1, and contacts with described feeding ratchet 3, and in described feeding ratchet 3 reciprocating motion at intermittence processes, described retaining ratchet 6 maintains the lock status with described ratchet integrated wheel 4, to stop described rack blade 5 rollbacks.
