Abstract

The utility model discloses a glass cutter with rotating and swinging frontward and backward, in particular to a glass cutting appliance which is used by hand. The cutter head of the existing glass cutting cutter is fixed on the cutter bar, and one point of the diamond cutter tip is contacted with the cutting surface, which makes the existing glass cutting cutter take the trouble and control difficulty, and makes the cutting of the circular glass and the cambered surface shape glass become more difficult. In the utility model, the cutter head and the cutter head cleat of the lower end of the cutter bar shaft are movably connected through a male pin shaft, the cutter head can rotate at 360 DEG and swing frontward and backward, and the circle (curve) glass and the cambered surface shape glass can be rapidly cut no needing of the rotation of the body. A bearing surface which is arranged on the cutter head and the diamond tip are simultaneously contacted with the cutting surface, which ensures the cutting angle is fixed and unchanged.

Description

Glass cutter with rotating and swinging bit

The novel glass cutter of the rotatable and swing of cutter head is a kind of hand glass cutting utensil.

Existing glass cutting cutter, its structure are that the cutter head that is welded with the diamond point of a knife is fixed on the knife bar, and steel cutter hammer is arranged at the knife bar bottom; Want hard the strict angle of grasping knife bar, keeping diamond point of a knife and cut surface of wrist during cutting, improper use very easily damages glass; During glass that especially incising circular, curved surface and area are bigger, just more apparent effort, difficulty.

The purpose of this utility model is to solve the above-mentioned deficiency of existing glass cutting cutter, a kind of be convenient to grasp (contact angle of diamond point of a knife and cut surface can remain unchanged) is provided, cutter head can be made the hand novel glass cutters of 360 degree rotations and swing on cut surface, be suitable for incising circular (curve), globoidal glass especially.

Principal character of the present utility model is that its knife bar overlaps and cutter spindle can be done the circumference rotation each other, the cutter head clamping plate and the pin axle that are linked to the cutter spindle lower end flexibly connect, but make cutter head to do swing in 360 degree rotation cuttings of cutting planes upper edge cutting board do and tool setting head-clamp plate; One bearing surface is set on the cutter head, makes it when work, contact cut surface simultaneously, keep the angle of diamond point of a knife and cut surface constant all the time with the diamond point of a knife.

Accompanying drawing has been described an embodiment of the present utility model.

Fig. 1 is the structural representation of the novel glass cutter of the rotatable and swing of cutter head.

Fig. 2 is the utility model structure side view.

As shown in the figure, knife bar cover of the present utility model (2) and cutter spindle (3) can rotate around making circumference each other, cutter head clamping plate (4) and cutter spindle (3) or welding or whole the connection, cutter head (6) can be on cutting planes is that rotating shaft is done 360 ° of rotation cuttings along cutting board with cutter spindle (3), human body need not rotate incising circular (curve) glass promptly, cutter head (6) can pin axle (5) be the center of circle also, the swing (about 45 °) of making an arc before and after the tool setting head-clamp plate (4), make feed on convex-concave arc glass face, cutter head (6) can be with the swing that rises and falls of cambered surface angle, adapt to the variation of angle, guarantee the edge of a knife.

Diamond point of a knife (7) is placed in cutter head A point one side, and the central axis of cutter spindle (3) is near diamond point of a knife (7), can make reactive force put on the cutting point of a knife better and that cutter head is rotated is brisk; In the B of cutter head (6) point one side one bearing surface (10) is set, bearing surface is lower than the diamond point of a knife, because cutter head (6) swing but make an arc in tool setting head-clamp plate (4) front and back, bearing surface during work (10) contacts cut surface and one-tenth level simultaneously with diamond point of a knife (7), bearing surface (10) but effect be the angle of fixed diamond point of a knife and cut surface, thereby guarantee the best edge of a knife.

What cutter head (6) had lubricated diamond point of a knife and a glass surface contains soft hole of glossy cutter (8), in the profit soft nib of cutter (9) patchhole, aside also have in order to hold the R nest (11) of soft nib, soft nib is hidden in this during work, and a shake mouthful ball (1) is connected with cutter spindle (3) body and knife bar cover (2) stays certain interval (cutter spindle (3) and knife bar cover (2) can be rotated each other); Glass in order to after vibrations are cut gently makes it to separate along tangent line.

The utility model novel structure, opposite side at the diamond point of a knife of cutter head is provided with the cutting bearing surface, contact cut surface simultaneously with point of a knife during cutting, the cutting angle (otch) that can guarantee point of a knife is constant all the time, avoided existing cutter to be difficult for grasping the defective of fragile glass of improper use and effort; Cutter spindle and knife bar cover can rotate each other, the lower end cutter head clamping plate of cutter head and cutter spindle flexibly connect with the pin axle, cutter head can be done 360 degree rotations along template on cutting planes, make the utlity model has to need not to rotate the characteristics that health gets final product incising circular (curve) glass; Cutter head is done swing by pin axle tool setting head-clamp plate, easily the cutting arc surface glass.

The maintenance that cutter head glass cutter rotatable and swing is suitable for glass production producer, construction sector and office building, dwelling house is used, and it is simple in structure, is easy to manufacture.
