For solving the problems of the technologies described above, the utility model provides a kind of oil nozzle screw assembling screwdriver, comprises knife bar and cutter head, it is characterized in that,
Described cutter head is a word cutter head, and the side of a described word cutter head is provided with projection, and the top of described projection is concordant with a described word cutter head top.
Above-mentioned oil nozzle screw assembling screwdriver also can have following features,
Described projection comprises first protruding and the second projection, described first projection is arranged on the side of a described word cutter head, described second projection is arranged on the opposite side of a described word cutter head, and described first projection, the second projection form Z-type structure cutter head with a described word cutter head.
Above-mentioned oil nozzle screw assembling screwdriver also can have following features,
Described first protruding with described second projection centered by symmetrical.
Above-mentioned oil nozzle screw assembling screwdriver also can have following features,
The end face of described first projection is provided with polyether-ether-ketone coating.
Above-mentioned oil nozzle screw assembling screwdriver also can have following features,
For being welded to connect between described first projection and a described word cutter head.
Above-mentioned oil nozzle screw assembling screwdriver also can have following features,
The end face of described second projection is provided with polyether-ether-ketone coating.
Above-mentioned oil nozzle screw assembling screwdriver also can have following features,
For being welded to connect between described second projection and a described word cutter head.
The utility model technique scheme has following beneficial effect:
The utility model can solve problems of the prior art, can realize the quick assembling of oil nozzle screw; Concrete, the said structure that the utility model provides can realize the quick assembling of oil nozzle screw in fact, can effectively prevent cutter head from skidding off bottom flat recess, and can effectively prevent cutter head energy flat recess side from skidding off, can improve and agree with stability in operating process, can efficiency of assembling be improved.
Other features and advantages of the utility model will be set forth in the following description, and, partly become apparent from description, or understand by implementing the utility model.The purpose of this utility model and other advantages realize by structure specifically noted in description, claims and accompanying drawing and obtain.
Accompanying drawing explanation
Accompanying drawing is used to provide the further understanding to technical solutions of the utility model, and forms a part for description, is used from explanation the technical solution of the utility model, does not form the restriction to technical solutions of the utility model with the embodiment one of the application.
Fig. 1 is the structural representation of the utility model embodiment;
Fig. 2 is oil nozzle screw structural schematic diagram.
Detailed description of the invention
For making the purpose of this utility model, technical scheme and advantage clearly understand, hereinafter will be described in detail to embodiment of the present utility model by reference to the accompanying drawings.It should be noted that, when not conflicting, the embodiment in the application and the feature in embodiment can be combined mutually.
Shown in composition graphs 1 and Fig. 2, the utility model provides a kind of oil nozzle screw 5 and assembles screwdriver, comprises knife bar 3 and cutter head, it is characterized in that,
Described cutter head is a word cutter head 1, and the side of a described word cutter head 1 is provided with projection, and the top of described projection is concordant with described word cutter head 1 top.
In the utility model concrete operations, an above-mentioned word cutter head 1 can be stretched in the flat recess structure at oil nozzle screw 5 cap place from the side, and then realize clamping oil nozzle screw 5 cap by protruding, the smooth installation of oil nozzle screw 5 can be realized simultaneously.
Preferably, in the utility model concrete operations,
Described projection comprises the first protruding 2 and second projection 4, described first projection 2 is arranged on the side of a described word cutter head 1, described second projection 4 is arranged on the opposite side of a described word cutter head 1, and described first projection 2, second protruding 4 forms Z-type structure cutter head with a described word cutter head 1.
In the utility model concrete operations, be symmetrically arranged with the first protruding 2 and second projection 4, can realize clamping operation simultaneously, can improve the stability of operation further at flat recess two ends by above-mentioned, when effectively can avoid assembly manipulation, cutter head skids off.Further, described first protruding 2 with described second projection 4 centered by symmetrical.
Preferably, in the utility model concrete operations, the end face of described first projection 2 is provided with polyether-ether-ketone coating; The end face of described second projection 4 is provided with polyether-ether-ketone coating.
In the utility model concrete operations, by spraying above-mentioned polyether-ether-ketone coating, effectively can strengthen the end-face friction of the first projection 2, second projection 4, can, in concrete operations, effectively avoid cutter head overall structure to skid off from flat recess side; The setting of above-mentioned polyether-ether-ketone coating, finally effectively can strengthen the frictional force between cutter head entirety and flat recess.Concrete, for being welded to connect between described first protruding 2 and a described word cutter head 1; For being welded to connect between described second protruding 4 and a described word cutter head 1.
The said structure that the utility model provides can realize the quick assembling of oil nozzle screw 5 in fact, can effectively prevent cutter head from skidding off bottom flat recess, and can effectively prevent cutter head energy flat recess side from skidding off, can improve and agree with stability in operating process, can efficiency of assembling be improved.
Although it is apparent to those skilled in the art that embodiment disclosed by the utility model as above, the embodiment that described content only adopts for ease of understanding the utility model, and be not used to limit the utility model.Those of skill in the art belonging to any the utility model; under the prerequisite not departing from the spirit and scope disclosed by the utility model; any amendment and change can be carried out in the form implemented and details; but scope of patent protection of the present utility model, the scope that still must define with appending claims is as the criterion.
