Abstract

Arbitrary glass cutter is the glass cutting instrument, and it resembles tallboy and is buckled on the glass surface, and is vertical with rim of a cup control cutter hub, comes the kerf quality of the universal cutter in assurance center, perfectly safe.87201847.4 novel patent cutter, but the automatic capturing and the control edge of a knife, having changed present old-fashioned cutter needs to look around for the shortcoming of grasping the edge of a knife with certain technical experience.But the about phenomenon of the control knife bar of still needing.Otherwise also can occur not having mouthful and damaged glass, the present invention occurs with brand-new form and function, makes the people that can not cut glass, can draw or writes on glass the cutting arbitrarily of different thickness, can both be along the line cracking.

Description

Free-cutting glass cutter

Free-cutting glass cutter is a kind of glass cutting instrument, and it resembles tallboy and is buckled on the glass surface, and it is vertical to be close to glass surface control cutter hub with rim of a cup, to guarantee universal cutter kerf quality, perfectly safe.

The patent No. 872018474 novel glass cuttves, but the automatic capturing and the control edge of a knife have changed present glass cutter and will adjust the knife bar angle with technical experience, seek the shortcoming of grasping the edge of a knife.But still need with the about phenomenon of hand control knife bar, otherwise mouth also can occur not having and damage glass.

The objective of the invention is to overcome the deficiencies in the prior art, make the people that can not cut glass draw, map, can both come out with brand-new form and peculiar function along the line cracking on glass the cutting arbitrarily of different thickness.

The objective of the invention is to realize with following technical scheme.

This free-cutting glass cutter has a slip swivel knife shaft (6), be through in copper bush (5) hole, copper bush (5) screws in cutter hub rim of a cup center from cutter hub (2) below by screw, the upper end of cutter shaft (6) and rotation top (4) wringing fit, in order to avoid cutter shaft is deviate from, rotate and adorn a pressure slider (3) above top (4), compressed by spring (7), above the spring (7) pressure adjustment screw (8), have the top that small ball screw cap (9) is tightened on cutter hub (2), diamond cutter head (10) is contained in the hole bottom of universal cutter shaft (6), and eccentric 2mm is to satisfy universal rotation.

Fig. 1 is the structural representation of arbitrary glass cutter.

(2)-cutter hub shown in the figure, (3)-slide block, (4)-rotation is top, (5)-copper bush, (6)-swivel knife shaft, (7)-spring, (8)-adjust screw, (9)-screw cap.

Free-cutting glass cutter is adjusted screw (8) under quiet moving state, make compression spring (7) be in required pressure state, and diamond segment (10) protrudes in rim of a cup.When glass-cutting, with the little rim of a cup of have gentle hands flicking lower knife body (2) lower end, cutter head (10) is pressed into rim of a cup, enough cut the pressure of glass simultaneously, and upwards promote cutter shaft (6), and promote rotation top (4), top (4) upwards promote slide block (3) compression spring (7).And the pressure of spring (7) is to adjust accurately in advance by adjusting screw.Behind cutter head (10) the incision glass, when mobile cutter hub is cut when cutting a piece of glass the just universal freely rotation at the rim of a cup center of cutter shaft arbitrarily, lubricating oil passes through inside groove, oozing to the lubricated otch of cutter head, can draw arbitrarily as universal bow pen, is the ideal tools of cutting abnormal shape, Idiotype glass.

Claims (3)

1. A kind of free-cutting glass cutter

   1, point of a knife one is lighted face, and with technology and experience, armrest is sought and grasped the shortcoming that the edge of a knife is existing glass cutter.The invention is characterized in described free-cutting glass cutter, is to rely on glass surface to set upright cutter hub, control the best edge of a knife, and the following rim of a cup of cutter hub (2) is buckled in when sliding on the glass surface, and the universal cutter shaft at rim of a cup center is all the time perpendicular to glass surface.
2. 2, according to the described arbitrary glass cutter of claim 1, it is characterized in that cutter hub (2) rim of a cup center tightly is rotary with copper sheathing (5), (5) be with the universal cutter shaft (6) of band diamond segment (10) in the hole, (6) top wringing fit has top (4), (4) withstand on the lower plane of pressure slider (3), (3) top pressed by pressure spring (7), and the pressure of spring (7) comes self aligning screw (8), and the semisphere screw cap tightly is spun on the upper end of cutter hub (2).
3. 3, described according to claim 1 or 2, free-cutting glass cutter is characterized in that, utilizes glass surface to support, and guarantees that edge of a knife quality is a key point of the present invention.
