Abstract

A tube cutting knife relates to a manual cutting tool, in particular to the cutting knife to cut the hollow round tube. An upper knife seat and a lower knife seat of the utility model are installed symmetrically with two pieces of knife plates on basis of traditional combination of the knife plate of upper knife seat and lower knife seat and a handle. The two sides of the lower knife seat are all hinged with a connection rod, and the upper knife seat is provided with a continuous manger. The external side of the continuous manger is fixed with a tooth plate, and the connection rod is provided with a lateral lever passing the continuous manger. The device takes advantages of simple structure, and suits much more for the operation in the narrow space with a higher cutting efficiency.

Description

A kind of pipe cutter

" technical field "

The utility model belongs to manual cutting element, particularly cuts the cutter of hollow circular tube.

" technical background "

Traditional pipe cutter is made up of the handle that is loaded on the blade in the upper and lower tool rest and compress tool rest one end, and this cutter faces in upper and lower tool rest respectively adorns a slice blade, when the screw rod of pressing handle, and blade stressed not good, damage easily; In narrow spatial operation inconvenience, need 180 ° of turning handles, just can be cut to the whole circumference of pipe; The adjusting range of cutting pipe is very little.

" summary of the invention "

The technical problems to be solved in the utility model is, a kind of improved pipe cutter is provided, and it is simple in structure, and preferably it is higher to cut off efficient in the narrow space operation, and suitable pipe scope is wider.

Technological means of the present utility model is: form on the basis at traditional blade and handle by being loaded in the upper and lower tool rest, each symmetry is adorned two blades in upper cutter head and following tool rest, the angle that the point of contact of adjacent knife blades and pipe center constitute is 90 °, each hinged connecting rod of following tool rest bilateral symmetry, upper cutter head has groove, groove outside fixed tooth plate, connecting rod are connected to a cross bar that passes groove.

The upper cutter head of this cutter and following tool rest symmetry are packed into behind two blades, and the point of contact is increase symmetrically also, can make the stressed dispersion of blade many, so can be improved in the life-span of blade; And every 90 ° of angles a point of contact is just arranged on the circumference of pipe, do not need very big space with regard to rotatable handles, turning handle just can cut to whole circumference in 90 ° scope, the practical operation of being more convenient for; In certain caliber scope, when cutting diameter is big, cross bar can be adjusted to the lower end of groove, snap in again in the corresponding tooth plate, the pressing handle screw rod, turning handle just can cut off gradually; When pipe diameter hour, then cross bar is transferred in the groove upper end and blocked.

" description of drawings "

Fig. 1 is a structural representation of the present utility model.

Each label is represented successively among the figure: handle 1, link 2, screw rod 3, rill 4, upper cutter head 5, blade 6, tooth plate 7, cross bar 8, groove 9, connecting rod 10, following tool rest 11.

" specific embodiment "

Referring to a specific embodiment shown in Figure 1, the following tool rest 11 of this pipe cutter is articulated on " U " type link 2, upper cutter head 5 and following tool rest 11 each symmetry are equipped with two blades 6, the lower end of each articulated linkage 10 of the bilateral symmetry of following tool rest 11, upper cutter head 5 has groove 9, and the outside of groove 9 has a tooth plate 7 to be fixed on the upper cutter head 5, and connecting rod 10 upper ends in both sides link together with cross bar 8, cross bar 8 passes groove 9 again, and upper cutter head 5 and following tool rest 11 are linked into an integrated entity.During use, unclamp screw rod 3, pipe is put into down in the blade 6 of tool rest 11, the upper cutter head 5 that closes snaps in the tooth of suitable tooth plate 7 cross bar 8, screws screw rod 3 again, as long as turning handle 1 just can cut to whole circumference in 90 ° scope, pipe is cut off.Fixed for opening one end that makes upper cutter head 5 and following tool rest 11, screw rod 3 ends and upper cutter head 5 correspondence positions of handle 1 have rill 4.

From technique scheme of the present utility model, it is simple in structure, and preferably it is higher to cut off efficient in the narrow space operation, and suitable pipe scope is wider.

Claims

1, a kind of pipe cutter, mainly form by the blade and the handle that are loaded in the upper and lower tool rest, it is characterized in that upper cutter head and following each symmetry of tool rest are equipped with two blades, each hinged connecting rod of following tool rest bilateral symmetry, upper cutter head has groove, groove outside fixed tooth plate, connecting rod are connected to a cross bar that passes groove.

2, by the described pipe cutter of claim 1, it is characterized in that having rill at the screw rod end and the upper cutter head correspondence position of handle.
