Utility model content:
The purpose of this utility model is exactly the deficiency for prior art, and a kind of perching knife of the use of keeping a public place clean 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 perching knife of the use of keeping a public place clean, comprise holder, handle and blade that blade is installed, handle is welded on the rear end face of holder, the front end face of holder forms the translot that runs through holder two side, on the holder of translot rear side, form gathering sill, in gathering sill, be inserted with pushing block, the front end of pushing block is fixed with blade, and blade sleeve is in the translot of holder; Screw rod has been pressed in the rear end of pushing block, and screw rod is screwed onto on swivel nut through holder and handle, and swivel nut is hinged on the rear end of handle; On the rear end face that one end of extension spring is fixed on pushing block, the other end is fixed on gathering sill.
Described blade is plugged on pushing block and by bearing pin and is fixed on pushing block, and the width of described blade is less than the degree of depth of translot.
Described pushing block is elongated, and the length of pushing block equals the length of gathering sill.
The rear end of described pushing block forms groove, and screw rod is placed in groove, in the rear end face of gathering sill, forms slot, and extension spring is placed in slot.
Described holder is comprised of pedestal and pressing plate, and pressing plate is fixed on pedestal, and described translot and gathering sill are all molded on the upper surface of pedestal and pressing plate and the lower surface of pressing plate.
Swivel nut and handle articulated structure are: on the outside of handle rear end, form annular draw-in groove, the front end of swivel nut forms the annular Connection Block 31 that cross section is L-type, and the front end holding of annular Connection Block is in the draw-in groove of handle.
The beneficial effects of the utility model are:
It has designed a kind of structure that can hide blade, thereby makes its perching knife when not using, hide the point of a knife of blade, avoids causing personal injury, has improved the safety of perching knife.
Accompanying drawing explanation:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is cross-sectional schematic of the present utility model;
Fig. 3 is the structural representation that the utility model changes angle.
In figure: 1, holder; 2, handle; 3, swivel nut; 4, blade; 5, pushing block; 6, bearing pin; 7, extension spring; 8, screw rod; 11, pedestal; 12, pressing plate; 13, translot; 14, gathering sill; 15, slot; 16, groove; 21, draw-in groove; 22, annular Connection Block.
The specific embodiment:
Embodiment: see shown in Fig. 1 to 3, a kind of perching knife of the use of keeping a public place clean, comprise holder 1, handle 2 and blade 4 that blade is installed, handle 2 is welded on the rear end face of holder 1, the front end face of holder 1 forms the translot 13 that runs through holder 1 two side, on the holder 1 of translot 13 rear sides, forms gathering sill 14, is inserted with pushing block 5 in gathering sill 14, the front end of pushing block 5 is fixed with blade 4, and blade 4 sleeves are in the translot 13 of holder 1; Screw rod 8 has been pressed in the rear end of pushing block 5, and screw rod 8 is screwed onto on swivel nut 3 through holder 1 and handle 2, and swivel nut 3 is hinged on the rear end of handle 2; One end of extension spring 7 is fixed on pushing block 5, the other end is fixed on the rear end face of gathering sill 14.
Described blade 4 is plugged on pushing block 5 and by bearing pin 6 and is fixed on pushing block 5, and the width of described blade 4 is less than the degree of depth of translot 13.
Described pushing block 5 is elongated, and the length of pushing block 5 equals the length of gathering sill 14.
The rear end of described pushing block 5 forms groove 16, and screw rod 8 is placed in groove 16, forms slot 15 in the rear end face of gathering sill 14, and extension spring 7 is placed in slot 15.
Described holder 1 is comprised of pedestal 11 and pressing plate 12, and pressing plate 12 is fixed on pedestal 11, and described translot 13 and gathering sill 14 are all molded on the upper surface of pedestal 11 and pressing plate 12 and the lower surface of pressing plate 12.
