Abstract

The utility model discloses a putty knife which comprises a knife body and a shank. An elongated hole slot is formed in the shank, the bottom part thereof is fixedly connected with a magnet; a screwdriver is absorbed onto the magnet, and the tail part thereof is matched with the elongated hole slot. The utility model has the advantages that through forming the elongated hole slot in the shank, fixedly connecting the bottom part of the elongated hole slot with the magnet and absorbing the screwdriver onto the magnet, the putty knife not only can build walls and plaster, but also can directly use the screwdriver to carry out relevant operation when a bolt is required to be screw down or removed, thereby bringing along great convenience to a builder; and because the screwdriver is absorbed onto the magnet, a screw is not required to be fixed by adopting other fixing devices, so that the structure is simpler.

Description

A kind of putty knife

Technical field

The utility model relates to a kind of building operations instrument, especially relates to a kind of putty knife.

Background technology

Putty knife is usually used in building a wall, plastering in building construction process etc., traditional putty knife generally comprises cutter hub and handle of a knife, handle of a knife is provided with a groove that holds the bottom of cutter hub, the bottom of cutter hub is fixedly connected in the groove, this traditional putty knife all only has a kind of single function, just is used for building a wall, plasters, Puttying etc.But in building construction process, tend to run into and find that needs are tightened when just plastering and maybe need the screw removed or the like situation, if constructor's work in the hand of stopping at this moment, remove to seek screwdriver and twist or remove screw, seek screwdriver so and will spend constructor's regular hour, this will directly influence the progress of construction.

Summary of the invention

Technical problem to be solved in the utility model provides a kind of simple in structure, easy to use, and the putty knife with screwdriver function.

The utility model solves the problems of the technologies described above the technical scheme that is adopted: a kind of putty knife, comprise cutter hub and handle of a knife, be provided with microscler hole slot in the described handle of a knife, the bottom of described microscler hole slot is fixedly connected with magnet, be adsorbed with screwdriver on the described magnet, the afterbody of described screwdriver matches with described microscler hole slot.

The cross section of described microscler hole slot be shaped as hexagon, the cross section of described magnet be shaped as circle, the radius of described circle equals described hexagonal external radius of a circle.

The bottom of described handle of a knife is connected with the handle of a knife lid, and described handle of a knife covers and is provided with connecting portion, and described connecting portion is provided with projection, and the inwall of described handle of a knife is provided with groove, and described projection snaps in the described groove.

Compared with prior art, advantage of the present utility model is by a microscler hole slot is set in handle of a knife, the fixedly connected magnet in the bottom of microscler hole slot, screwdriver of absorption on the magnet, make that like this this putty knife not only can be used to build a wall, plaster, and need tighten or when removing screw when running into, can directly use screwdriver to carry out associative operation, bring great convenience to the constructor, and because screwdriver is adsorbed on the magnet, need not by other fastening devicess screwdriver to be fixed, structure is more simple.Because the cross section of the afterbody of common employed screwdriver is a hexagon, therefore the utility model is designed to hexagon with microscler hole slot, and the radial design of the magnet of circle is become with the external radius of a circle of the cross section of microscler hole slot to equate, can the magnet of circle be stuck in firmly the bottom of microscler hole slot like this by external force, and the afterbody of screwdriver also just is embedded in the microscler hole slot, make that the connection of screwdriver is more reliable, in addition because handle of a knife adopts plastics to make, so the radius of circular magnet also can be slightly larger than the external radius of a circle of the cross section of microscler hole slot.Connect the handle of a knife lid by bottom at handle of a knife; handle of a knife covers connecting portion is set; projection is set on the connecting portion; the inwall of handle of a knife is provided with groove, like this when not using screwdriver, in the connecting portion insertion handle of a knife with the handle of a knife lid; projection on the connecting portion just snaps in the groove on the inwall of handle of a knife; play the effect of protection screwdriver, when need use screwdriver, firmly the handle of a knife lid is extracted and got final product.

Description of drawings

Fig. 1 is an overall structure schematic diagram of the present utility model;

Fig. 2 does not comprise the decomposition texture schematic diagram of cutter hub for the utility model.

The specific embodiment

Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.

As shown in the figure, a kind of putty knife, comprise cutter hub 1 and handle of a knife 2, handle of a knife 2 is prepared from by plastics, the end of cutter hub 1 is fixedly connected on the head of handle of a knife 2 by rivet 10, also can adopt existing buckle mode to connect cutter hub 1 and handle of a knife 2, or the form that also can adopt rivet and buckle mode to combine is connected cutter hub 1 and handle of a knife 2.Be provided with microscler hole slot 3 in the handle of a knife 2, the bottom of microscler hole slot 3 is fixedly connected with magnet 4, be adsorbed with screwdriver 5 on the magnet 4, the afterbody of screwdriver 5 matches with microscler hole slot 3, such structure makes that this putty knife not only can be used to build a wall, plaster, and need tighten or when removing screw when running into, can directly use screwdriver 5 to carry out associative operation, bring great convenience to the constructor, and because screwdriver 5 is adsorbed on the magnet 4, need not by other fastening devicess screwdriver 5 to be fixed, structure is more simple.

Because the cross section of the afterbody of common employed screwdriver 5 is a hexagon, therefore in this specific embodiment the cross section of microscler hole slot 3 be shaped as hexagon, the cross section of magnet 4 be shaped as circle, circular radius equals hexagonal external radius of a circle, can the magnet 4 of circle be stuck in firmly the bottom of microscler hole slot 3 like this by external force, and the afterbody of screwdriver 5 also just is embedded in the microscler hole slot, makes that the connection of screwdriver 5 and use are more reliable.

The bottom of handle of a knife 2 is connected with handle of a knife lid 6; handle of a knife lid 6 is provided with connecting portion 7; connecting portion 7 is provided with projection 8; the inwall of handle of a knife 2 is provided with and is used for and projection 8 grooves that match 9, when not using screwdriver 5, in the connecting portion insertion handle of a knife 2 with handle of a knife lid 6; projection 8 on the connecting portion 7 just snaps in the groove 9 on the inwall of handle of a knife 2; play the effect of protection screwdriver 5, when need use screwdriver 5, firmly handle of a knife lid 6 is extracted and got final product.
