Description

Combined multifunction compasses knife

The utility model relates to a kind of workpiece line or laying out apparatus.More particularly, be a kind of multifunctional assembled compasses cutter that constitutes by positioning disk, graduated scale and line cutter.

At present, the normally used compasses cutter of people mostly is homemade light instrument.In the prior art,, but can not be used widely owing to there is following weak point by a kind of compasses cutter of forming by metallic framework, rule and diamond cutter head.

1, it is little plate glass to be cut out the thickness range that cuts, and only is 3～6mm.

2, center of circle firm position is poor, causes use unreliable.

3, the diamond cutter head must use specific purpose tool to change or repair by the professional, causes inconvenient maintenance.

The purpose of this utility model is to avoid the deficiencies in the prior art part, provide a kind of use reliable, easy to maintenance, and can cut out the compasses cutter that cuts certain thickness plate glass.

The purpose of this utility model also is to provide a kind of straight line, circular arc line that collects plate glass to cut out and cut; Various sheet linears or camber line setting-out and write multiple function multifunctional assembled compasses cutter.

The purpose of this utility model is achieved through the following technical solutions.

The utility model is made of positioning disk, graduated scale and line cutter.

Of the present utility model being characterised in that:

A, described positioning disk are to be the chassis with the rubber suction cups, and the sucker top is a cambered surface sucker supporting base, and described sucker supporting base top center is fixed with the location axis, the outer nested location of axis, location axle sleeve.

B, be positioned at locating shaft cover top and have one

Shape vernier rod support, its

The shape groove has been embedded in slidably rule.The line cutter is installed in the rule termination.

Feature of the present utility model is that also described line cutter is a hollow circular cylinder, and its both ends and inner hollow section connect writing pen, glass cutter and delineation draw point with spiral respectively.

The utility model is compared prior art and is had following advantage.

1, adopt the rubber suction cups location, firm position is strengthened greatly, dependability improves.

2, the utility model sanction of being used for circular plate glass and eyeglass is cut, and scope can reach: diameter 100～1000mm, thickness 2～20mm.

3, glass cutter of the present utility model adopts combined type to install, and changes easily.

4, each parts of the utility model can carry out different combinations, also can use separately, and the straight line, circular arc line that is widely used in plate glass cut out and cut, various sheet linear or circular arc line setting-out and write.Described positioning disk cooperates with the annex handle, can be used for the carrying of small-sized plate glass and the installation of various glass door and windows.

Number in the figure: 1, turning handle, 2, handle set, 3, rubber suction cups, 4, the sucker supporting base, 5, the location axis, 6, the location axle sleeve, 7, Shape vernier rod support, 8, rule, 9, glass cutter, 10, the delineation draw point, 11, lettering pen, 12, lock-screw, 13, lock-screw, 14, help the chi bar, 15, handle, 16, the handle installing hole, 17, alloy blade, 18, knife rest.

By the following examples, in conjunction with the accompanying drawings, the utility model is further described.

Embodiment:

Referring to accompanying drawing, supported by metal sucker supporting base (4) as the rubber suction cups (3) of locating the chassis, be embedded with handle set (2) at rubber suction cups (3) central part, have chute through hole (see figure 3) on the handle set (2).Interlude is that the turning handle (1) of arc passes this chute through hole.The positioning through hole on the sucker supporting base (4) is passed at the both ends of turning handle (1) respectively.Rotate turning handle (1), handle set (2) is raised, promptly rubber suction cups (3) is bled, it is fixedly positioning.

Location axis (5) is fixed on sucker supporting base (4) top center, and location axle sleeve (6) is nested outside it, and being positioned at location axle sleeve (6) top has

Shape vernier rod support (7) (see figure 2), rule (8) are embedded in vernier rod support (7) In the shape groove, and can slide therein, locate rule (8) as required, be locked with screw (13).Help chi bar (14) to be used to keep the balance of rule (8).

The line cutter that is installed in rule (8) end is a hollow circular cylinder, and its both ends and hollow section are respectively with the writing pen that is threaded (11), glass cutter (9) and delineation draw point (10).

Glass cutter (9) adopts alloy blade (17), fixes with pin between blade (17) and the knife rest (18), releases pin and can change blade (17).Knife rest (18) center is an oil guiding hole so that the finish that is stored in the line cutter hollow section constantly oozes to blade (17).

Handle shown in Figure 5 (15) is installed in the handle installing hole (16) of sucker supporting base (4).Utilize this handle (15), make positioning sucker disk be used for the carrying of small-sized plate glass and the installation of glass door and window separately.
