Description
Technical field
The present invention relates to a kind of related fields of tool, particularly relate to a kind of tool combinations device of putty knife.
Background technology
" putty knife " be used in architectural engineering removing the residual paint of metope blade, due to cement craftsman on using ten frequency dividing
It is numerous, and it is larger to exert a force, therefore the structure between the blade of cutter and handle should have a special design, and existing putty knife structure be
The shank of blade pastes folder, and with rivet extends through upper clip, blade and lower clamping piece and fixes for upper and lower two intermediate plate is opposite, but
This class formation has the shortcomings that as follows on using.
First, in above structure in rivet using the situation loosened is tended to have after long, this is because chucking power is mainly
At rivet, and it is not the contact in face, therefore is being caused to loosen by lateral thrust；Furthermore since such upper and lower intermediate plate is most
It being made of timber, hardness is higher, therefore when forcing in cutter for a long time, it is easy to cause the problem of component is mutually disengaged.
Existing putty knife still has another structure, mainly equipped with duroplasts handle, in injection molding directly and blade
Shank (melt solid) combine, the more firm structure of a so available handle of a knife, but it also has shortcoming on the implementation.
Firstly, since handle of a knife should have certain thickness to be convenient to hold, but this thickness is after it is combined with blade,
Its cooling time is longer, is to make the manufacturing time of product long, improves its monovalent cost；In addition between handle of a knife and blade
Link is still to be easy to cause component to be mutually disengaged, and strengthens the bonding strength of handle of a knife and blade；Furthermore handle of a knife is all with duroplasts system
Into then its material consumption is more, causes to waste, especially to be become apparent in mass production；Due to cutter be through surface of scraping at
Reason, if by merging mold combined with duroplasts during, often result in the unavoidable friction with mold of cutter and cause
It scratches (trace)；Finally, it is another to be produced to increase, mold is quickly cooled down, using water as heat dissipation, then cutter whole body is immersed in the water, in
High temperature is reentered in cold water, is easily aoxidized and is got rusty.
Invention content
Technical problem underlying to be solved by this invention is, overcomes drawbacks described above of the existing technology, and provides one
Kind of tool combinations device, is integrally formed through blowing by connecting portion and lever or is connecting portion with made through injection
Into and lever to be blow molded made or be connecting portion with lever with ultrasonic welding etc., can not only reach it is easily assembled and
The effect of facilitating manufacture, and then manufacturing man-hours can be shortened with saving material, so as to reducing cost；Furthermore it can further keep away
Exempt from blade using when force it is excessive and cause connecting portion be detached from lever situation occur, connecting portion and lever can be strengthened by implying that
Bonding strength.
The technical solution adopted by the present invention to solve the technical problems is：
A kind of tool combinations device including a connecting portion, and is formed with a radial slot；One lever, through blow molding

Portion is engaged with an internal face of the radial slot and is fixed；The teeth portion is towards the knife portion direction and towards outer incline.
In the second embodiment of the present invention, the connecting portion is through made by injection, and the lever is through made by blowing；
There is an at least barb block, one end of the lever has a protrusion, which sets in the first end of the connecting portion
There is a barb ring, which is inserted into the first end of the connecting portion, and with an at least barb block and the mutual clasp of barb ring
It is fixed；The blade has a knife portion and a teeth portion, and the one end in the knife portion is connect with the teeth portion, which is inserted into being somebody's turn to do for the connecting portion
Radial slot, the teeth portion are engaged with an internal face of the radial slot and are fixed；The teeth portion is towards the knife portion direction and towards outer incline.
In the 3rd embodiment of the present invention, one forms a holding part with the lever of blow molding, one end of the lever,
And a barb is formed in holding part；And another connecting portion with injection molding, the openend of connecting portion are simultaneously equipped with a radial cut
Mouthful, and the opposite side of connecting portion is formed with barb block；And a blade, and with a knife portion and a teeth portion；Can so it make
Connecting portion is obtained when being placed in the holding part of lever, barb block can be fixed on the barb block of lever and mutually clasp is fixed；
And the teeth portion of blade is inserted into the radial slot of connecting portion so that teeth portion is engaged with the internal face of radial slot and is fixed.
In the fourth embodiment of the present invention, it is to be hot-melted welding with ultrasonic which connect with the lever；It should
The madial wall of the first end of connecting portion has concave ring groove and an internal projecting ring in one, which is set adjacent to the lever, this is interior
Concave ring groove abuts side of the internal projecting ring far from the lever, which has a protrusion, the protrusion adjacent to one end of the connecting portion
Lateral surface be equipped with a buckle bulge loop and a snap-in groove, the buckle bulge loop adjacent to the connecting portion set, the snap-in groove
The adjacent side of the buckle bulge loop far from the connecting portion, the interior concave ring groove are connected and fixed for the buckle bulge loop, which supplies
