Description
Technical field:
The utility model relates to the technical field of the aid of keeping a public place clean, more specifically to a kind of safe glass perching knife.
Background technology:
On glass after current people's finishing or floor, remain dirt impurity, some dirt impurity is easily cleaned with rag clear water, but some dirt impurity is bonded in easily scouring on glass or floor, thereby needs perching knife to clear up.And existing perching knife is generally holder and a blade composition that has handle and blade can be installed, the point of a knife of blade is exposed at holder outside, and it does not generally have safety device.While use, the point of a knife of its blade is still exposed at outside, abnormally dangerous.
Utility model content:
The purpose of this utility model is exactly the deficiency for prior art, and a kind of safe glass perching knife is provided, and it can easily hide the point of a knife of blade, thereby has improved security performance.
Technology solution of the present utility model is as follows:
A kind of safe glass perching knife, comprise the holder that blade is installed, handle and blade, handle is welded on the rear end face of holder, on the front end of holder, form the translot that runs through holder two side, translot upper, on bottom surface, form gathering sill, in gathering sill, be inserted with bearing pin, bearing pin is plugged on blade, blade sleeve is in the translot of holder, on described blade, form some slotted eyes, slotted eye divides the both sides that are positioned at bearing pin, the holder upper surface of described translot side is run through and is formed some stepped holes, on holder lower surface, form the screwed hole concentric with stepped hole, slotted eye on stepped hole and the blade of screw bolt passes holder upper end is screwed onto in the screwed hole of holder lower end.
Described bearing pin is positioned on the horizontal center line of blade, the rear end of blade leans against on the inner side end of holder, the slotted eye of blade is provided with 4, respectively there are 2 slotted eyes the both sides of the horizontal center line of blade, the distance of the slotted eye center line horizontal with blade all equates, slotted eye all equates with the distance of blade side.
Stepped hole on described holder and screwed hole are provided with two, and stepped hole and screwed hole lay respectively at the both sides of holder.
Described blade parallelogram, four angles of blade all form fillet.
Described handle tail end forms via hole, and bolt adopts the bolt with the stubborn handle of hand.
The beneficial effects of the utility model are:
It has used a kind of structure that can hide blade point of a knife, thereby makes its perching knife in the time not using, hide the point of a knife of blade, avoids causing personal injury, has improved the security of perching knife.
Brief description of the drawings:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation that the utility model changes angle;
Fig. 3 is the partial schematic sectional view at the utility model blade place.
In figure: 1, holder; 2, handle; 3, blade; 4, bearing pin; 5, bolt; 11, translot; 12, gathering sill; 13, stepped hole; 14, screwed hole; 21, via hole; 31, slotted eye.
Detailed description of the invention:
Embodiment: see shown in Fig. 1 to 3, a kind of safe glass perching knife, comprise the holder 1 that blade is installed, handle 2 and blade 3, handle 2 is welded on the rear end face of holder 1, it is characterized in that: on the front end of holder 1, form the translot 11 that runs through holder 1 two side, translot 11 upper, on bottom surface, form gathering sill 12, in gathering sill 12, be inserted with bearing pin 4, bearing pin 4 is plugged on blade 3, blade 3 sleeves are in the translot 11 of holder 1, on described blade 3, form some slotted eyes 31, 31 points of slotted eyes are positioned at the both sides of bearing pin 4, holder 1 upper surface of described translot 11 sides is run through and is formed some stepped holes 13, on holder 1 lower surface, form the screwed hole 14 concentric with stepped hole 13, bolt 5 is screwed onto in the screwed hole 14 of holder 1 lower end through the slotted eye 31 on stepped hole 13 and the blade 3 of holder 1 upper end successively.
Described bearing pin 4 is positioned on the horizontal center line of blade 3, the rear end of blade 3 leans against on the inner side end of holder 1, the slotted eye 31 of blade 3 is provided with 4, respectively there are 2 slotted eyes 31 both sides of the horizontal center line of blade 3, the distance of slotted eye 31 center line horizontal with blade 3 all equates, slotted eye 31 all equates with the distance of blade 3 sides.
Stepped hole 13 on described holder 1 and screwed hole 14 are provided with two, and stepped hole 13 and screwed hole 14 lay respectively at the both sides of holder 1.
Described blade 3 parallelograms, four angles of blade 3 all form fillet.
Described handle 2 tail ends form via hole 21, and bolt 5 adopts the bolt with the stubborn handle of hand.
Operation principle: a kind of structure that can hide blade point of a knife of the utility model design, it is by taking off bolt 5, rotating blade 3 gathering sill 12 prolonging on holder 1 move, thereby the position of the point of a knife of blade 3 is changed in translot 11, the bolt 5 of screwing on again just can avoid causing personal injury, the security that has improved perching knife.
