In order to realize above-mentioned technical characteristic, the object of the present invention is achieved like this: optical cable cutting implement, it includes hand The tail portion of tube-holding body, the hand-held cylinder is fixedly installed with tailstock, is fixed with end cap by round nut locking on its head, described Hand-held cylinder is internally provided with piston cavity, and passing through to be slidably installed inside the piston cavity has piston body, the work Cock body is fixedly linked with the piston rod being arranged in inside piston cavity, and the other end of the piston rod is connected with push rod, described to push away Bar passes through end cap, and the push rod is hinged and connected by the bottom end of link mechanism and movable blades, and the movable blades pass through shaft It is hinged in fixed blade, the two, which matches to merge, realizes shearing, and the fixed blade is fixedly mounted on by plough bolt In blade mounting base, the blade mounting base is fixed on the top of end cap, is equipped with inside the tailstock for controlling high pressure gas The control valve rod that body enters, the tail portion center of the tailstock is machined with the tracheae connecting hole for being connected with high-pressure air pipe.

The intermediate position of the hand-held cylinder has been uniformly arranged skid resistance strip.

The link mechanism includes connecting rod, and one end of the connecting rod is hinged and connected by the end of the first pin shaft and push rod, The other end of the push rod is hinged and connected by the bottom end of the second pin shaft and movable blades, first pin shaft and the second pin shaft it Between bayonet lock for fixing to it is installed.

The bottom end of the control valve rod is equipped with closure column, the bottom cylindrical hole for blocking column and processing inside tailstock It matches, the top of the control valve rod is provided with cascade ring, the top cylindrical hole of the cascade ring and processing inside tailstock It matches, the bottom cylindrical hole is connected with top circular hole, and the tail portion of the bottom cylindrical hole, which is fixedly installed with, carries out it The bottom of closure blocks nut.

The annulus area A of the cascade ring is greater than the end end face annulus area B for blocking column；The control valve rod passes through tail Seat, and the bottom end face of its top and pressing plate is engaged, and the tail portion of the pressing plate is hinged on tailstock by pressing plate pin shaft.

It is communicated with inclined hole on the side wall in the top cylindrical hole, is fixed on the inclined hole oblique for what is blocked to it Hole blocks nut；Through air inlet is machined on the bottom cylindrical hole, the air inlet is connected with tracheae connecting hole；It is described Through-hole between bottom cylindrical hole and top cylindrical hole, which runs through, is machined with piston cylinder air inlet, the piston cylinder air inlet and piston Cavity is connected.

The inside plugging mechanism of the piston cavity being internally provided with for being blocked to it, the internal stopple plugging machine Structure includes the annular groove processed inside piston cavity, has the first sealing ring by circlip limit installation inside the annular groove, The outer cover that first sealing ring is matched with piston cavity is equipped with the first sealing ring, first sealing ring and piston rod phase Cooperation is internally provided with the second sealing ring；The outer cover that the outside of the piston body is matched with piston cavity is close equipped with third Seal.

The support ring assemblies of the piston cavity being internally provided with for being supported to push rod, the support ring assemblies Including support ring, the support ring is sleeved on the outside of push rod, in the outer cover that support ring and piston cavity match equipped with the Four sealing rings.

The inside of the end cap is fixed with guide sleeve, and the outside of the guide sleeve and push rod is all machined with mutually matched lead To keyway, feather key is installed between the guide key groove.

The operating method of the optical cable cutting implement, it including the following steps:

Step1: the tracheae of high-pressure air source is connected with tracheae connecting hole, and controls the closure column and air inlet phase of valve rod at this time Cooperation, and it is blocked；

Step2: the optical cable sheared will be needed to be arranged between movable blades and fixed blade；

Step3: when needing to shear, manually pressing pressing plate, by pressure control valve bar under pressing plate, blocks column at this time for downlink, this When air inlet will be leaked out, high pressure gas will enter bottom cylindrical hole by air inlet, then be entered by piston cylinder air inlet To piston cavity, high pressure gas will push piston body at this time, and then push piston rod by piston body；

Step4: it is driven again by piston rod driving push rod by push rod drive link, then by connecting rod by piston rod drive link mechanism Dynamic movable blades are rotated by movable blades around shaft, and then by the cooperation between movable blades and fixed blade, are realized It shears the end of optical cable；

Step5: after completing to its shearing, unclamping pressing plate, at this time the pressure of the high pressure gas inside piston cavity and bottom circle Post holes is identical with the pressure inside top cylindrical hole, and high pressure gas is greater than it to closure column to the pressure of cascade ring bottom at this time Pressure, controlling valve rod at this time will rise under force action, rise again so that blocking column, block to air inlet, And then stopping gas supply, piston body is by release at this time, and then unclamps movable blades and fixed blade, in order to shearing next time.

The method have the advantages that:

1, this cutting implement uses high-pressure air source as power source, and using the movement of link mechanism driving blade, final to realize Shearing work substitutes traditional manual work mode, greatly improves working efficiency, and the labour for reducing operating personnel is strong Degree.
