Description

The scissors of rapid shearing PVC tube

Technical field

The present invention relates to a kind of cutting implement, particularly relate to the scissors of rapid shearing PVC tube.

Background technology

The shearing employing of common pvc pipe is manual or power saws is sawed-off, wastes time and energy when operation, and simultaneously, the sawing mouth is inhomogeneous, and overlap or burr appear in regular meeting, influence the use of pipe.The utility model patent of application number 92232522.7 has disclosed a kind of plastic conduit scissors and has solved above-mentioned problem, comprise and cut handle and blade, be characterized in cutting between handle and be provided with the tooth bar linkage, tooth bar one end is positioned a left side by bolt and cuts a upper end, the two ends of connecting rod are pinned at respectively in the locating slot of tooth bar and blade, the blade afterbody has a little tooth to be meshed with tooth bar, and back-moving spring is housed on the bolt.But this technical scheme be because the in use difficult control of the tooth bar that adopts must have a little tooth to assist align rack the blade afterbody with hand, can normal running; In addition, because tooth bar is a linearity, relatively effort operates.

Summary of the invention

Technical problem to be solved by this invention is the present situation at prior art, and a kind of simple and reasonable, scissors of being convenient to the rapid shearing PVC tube of process and assemble, rapid operation is provided.It is by the strength of handle, with cooperating of the blade afterbody circle gear teeth and spring clip termination, and the quick laborsaving shearing pvc pipe purpose of breaking.

The present invention solves the problems of the technologies described above the technical scheme that is adopted: the scissors of rapid shearing PVC tube, comprise that handle is cut on an equipped mutually left side, handle and blade are cut in the right side, a left side is cut handle and is cut being hinged through bolt with the right side, blade inserts right cutting the notch of upper end and through bolt pin joint with it, the technical measures of taking comprise: the blade tail end has the gear teeth that rule is arranged, the knife block that inner tank mouths pin joint and apical grafting is had the button spring is cut on a left side, the tooth mouth of the corresponding butt gear teeth in the end of knife block;

And the blade breech face also is hinged with the blade pull bar, and blade pull bar via pins is connected with a hand lever, hand lever is stretched into a left side cut an inner tank mouths, and pin joint with it; Being positioned at a left side cuts the left side of the handle tie rod end relevant position of inner tank mouths cut inner tank mouths also is provided with alignment pin.

A left side is cut lower through-hole also is installed with steel wire; The shoulder that handle is cut on the right side also is hinged with centring ring.

Compared with prior art, blade tail end of the present invention has the gear teeth that rule is arranged, and the knife block that inner tank mouths pin joint and apical grafting is had the button spring, the tooth mouth of the corresponding butt gear teeth in the end of knife block are cut in a left side; And the blade breech face also is hinged with the blade pull bar, and blade pull bar via pins is connected with a hand lever, hand lever is stretched into a left side cut an inner tank mouths, and pin joint with it; Being positioned at a left side cuts the left side of the handle tie rod end relevant position of inner tank mouths cut inner tank mouths also is provided with alignment pin.The gear teeth of above-mentioned blade tail end and blade pull bar with hand lever is connected as a single entity, and cut with knife block, a left side, the right side cut matching, operate light and handy, simple and direct, convenient.

The specific embodiment

Embodiment describes in further detail the present invention below in conjunction with accompanying drawing.

Fig. 1 is to shown in Figure 4, and the scissors of rapid shearing PVC tube comprises that an equipped mutually left side is cut 2, the right side cuts 17 and blade 12, a left side cut 2 and the right side cut and be hinged 17 through bolt 5, bolt 5 ends tighten through jump ring 14; Blade 12 inserts right cutting the notch of 17 upper ends and through bolt 10 pin joint with it, and bolt 10 ends screw through nut 13; Blade 12 tail ends have the gear teeth 12a that rule is arranged, and cut on a left side has the knife block 6 of button spring 4 to 2 inner tank mouths through bolt 15 pin joints and apical grafting, and bolt 15 ends tighten through jump ring 18; The tooth mouth of the end of knife block 6 corresponding butt gear teeth 12a;

And blade 12 breech faces also are hinged with blade pull bar 9, and blade pull bar 9 via pins 8 are connected with a hand lever 7, hand lever 7 is stretched into a left side cut 2 inner tank mouths, and pin joint with it; Being positioned at a left side cuts the left side relevant position, hand lever 7 end of 2 inner tank mouths cut 2 inner tank mouths also is provided with alignment pin 3.

A left side is cut 2 lower through-hole also is installed with steel wire 1; The right side cut 17 shoulder also via pins 11 be hinged with centring ring 16.Operating process:

With a left side cut 2, the right side cut 17 and blade 12 draw back, blade pull bar 9 with hand lever 7 is opened; Pvc pipe is placed on the groove of scissors, and the knife edge of blade 12 is pressed on pvc pipe one side, and the left side of holding with a firm grip is cut 2, the tooth mouth of the end of knife block 6 corresponding butt gear teeth 12a is cut 17 on the right side; Just drive the gear teeth 12a motion of blade 12 tail ends along the tooth mouth of gear teeth 12a, make continuous afterburning shearing PVC tube one side of the knife edge of blade 12, when blade 12 arrives to groove, blade pull bar 9 with hand lever 7 is compressed; Gradually pvc pipe is sheared and disconnected.When blade 12 arrives to groove, the corresponding tooth mouth that breaks away from gear teeth 12a in the end of knife block 6.Prepare next time in order to circulate.

The gear teeth 12a of blade 12 tail ends and blade pull bar 9 with hand lever 7 is connected as a single entity, and cut 2 with knife block 6, a left side, the right side cuts and matches 17, operates light and handy, simple and direct, convenient.

Most preferred embodiment of the present invention is illustrated, and various variations or the remodeling made by those of ordinary skills can not depart from the scope of the present invention.
