Abstract
The invention provides a novel combined screw driver which comprises a plurality of tool bits and a handle, wherein a rod body used for mounting the tool bits is arranged on the handle; the handle is provided with a cavity; and the rear part of the handle is provided with a rear cover. The novel combined screw driver provided by the invention is characterized in that the handle of the screw driver is provided with the cavity and the tool bits which are not used can be directly placed in the hollow cavity, thereby preventing the tool bits from losing; the front part of the rod body on the handle of the screw driver is provided with an inner polygonal cavity and the peripheries of tool bits are made into polygonal shapes, thereby being capable of blocking the tool bits with the rod body in matching manner; and the bottom of the cavity is provided with a permanent magnet, which can catch up the tool bits firmly, thereby being convenient to mount the tool bits. The structure is simple.
Description
Technical field
The present invention relates to a kind of hardware ﹠ tools, relate in particular to a kind of combined screwdriver.
Background technology
Screwdriver is a kind ofly to be used for twisting screw to force its instrument in place, and a thin sphenocephaly is arranged usually, can insert in the line of rabbet joint or recess of screw cap, also claims by " screwdriver ".Mainly contain two kinds of a word (negative sign) and crosses (positive sign).Common hex(agonal)screw cutter in addition, hexagonal and outer-hexagonal are two kinds in comprising.Screwdriver generally is divided into normal screws cutter and combined screwdriver, the normal screws cutter is that a handle is made screwdriver together, prepares easily, can use as long as just take out, but, need to prepare various screwdriver sometimes because screw has a variety of different lengths and rugosity.And combined screwdriver is a kind of screwdriver that screw screwdriver bit and handle are separated, and when dissimilar screws is installed, only needs change the screw screwdriver bit just passable, does not need to prepare and carry a large amount of screwdrivers, and its benefit is to save the space, but loses the screw screwdriver bit easily.
Chinese invention patent (CN1489510A), a kind of combined screwdriver is disclosed, comprise that the elongate housing with a plurality of pipe tunnels, a plurality of driver bit, a plurality of elongate slide member, cutter head add clamping unit and sleeve, the combined screwdriver of this kind, mainly cutter head is positioned in the slender pipeline of shell, has avoided the loss of cutter head effectively, but its structure is complicated, cost is higher, lacks the market competitiveness.
Therefore, how to design a kind of simple in structurely, low-cost, can overcome simultaneously cutter head again and easily lose the combined screwdriver of shortcoming and become the problem that the present invention will solve.
Summary of the invention
At the demand, the invention provides a kind of improved novel combination type screwdriver, overcome whole or most distinct disadvantage of the prior art.
A kind of novel combination type screwdriver of the present invention comprises a plurality of cutter heads, handle, and wherein, handle is provided with the body of rod that cutter head can be installed, and described handle has cavity, and the handle rear portion is provided with bonnet.
In a preferred embodiment of the present invention, described cutter head is the polygon peripheral shape, and described lever front end has the inner polygon cavity that is complementary with the cutter head shape, and this cavity bottom also is provided with permanent magnet.
In a preferred embodiment of the present invention, described cutter head is a hexagonal perimeter shape.
The novel combination type screwdriver that the present invention discloses, the handle of screwdriver has cavity, and no cutter head directly is positioned in this cavity, makes cutter head be difficult for losing; And, the body of rod front portion of screw driver handle is provided with the inner polygon cavity, cutter head is manufactured the polygon peripheral shape, the cutter head and the body of rod can be fastened togather with mating, cavity bottom also has permanent magnet simultaneously, cutter head firmly can be held, realize installing easily and fast cutter head, and simple in structure.
Description of drawings
The present invention is further detailed explanation below in conjunction with the drawings and specific embodiments:
Fig. 1 is the schematic diagram after the assembling of embodiment of the invention novel combination type screwdriver;
Fig. 2 is the schematic diagram that the embodiment of the invention novel combination type screwdriver body of rod cooperates with cutter head;
Among the figure, the 1st, handle, the 2nd, bonnet, the 3rd, cutter head, 11 bodies of rod, the 12nd, cavity, the 13rd, polygon cavity.
The specific embodiment
In order to make those skilled in the art person understand technical scheme of the present invention better, and above-mentioned purpose of the present invention, feature and advantage can be become apparent more, the present invention is further detailed explanation below in conjunction with embodiment and embodiment accompanying drawing.
As shown in Figure 1, Fig. 1 is the schematic diagram of embodiment of the invention novel combination type screwdriver, in the embodiment of the invention, screwdriver comprises that mainly a plurality of cutter heads 3, these cutter heads are dissimilar cutter heads 3, criticize cutter head, little crosspoint tip screwdriver cutter head, grand cross as little flat blade screwdriver cutter head, spread-eagel and criticize cutter head, because cutter head is of a great variety, does not enumerate one by one at this, can freely cooperate according to different needs; Handle 1, the body of rod 11 that handle 1 is provided with, the body of rod 11 front ends can be installed different cutter head 3, in addition, handle is that the middle part is provided with cavity 12, and the handle rear portion is provided with bonnet 2, and handle cavity 12 inwalls are provided with screw thread, and bonnet is provided with the screw thread that is complementary with cavity inner wall equally, by screw thread bonnet is installed on the handle, when cutter head 3 does not use, can directly be positioned in the handle cavity, convenient and practical, be difficult for omitting cutter head.
Please continue to consult Fig. 2, Fig. 2 is the schematic diagram after the assembling of embodiment of the invention novel combination type screwdriver, the body of rod 11 front portions of screw driver handle 1 are provided with inner polygon cavity 13 among the figure, cutter head is manufactured the polygon peripheral shape, the cutter head 2 and the body of rod 11 can be fastened togather with mating, inner polygon cavity 13 bottoms also have the permanent magnet (not shown) simultaneously, cutter head firmly can be held, realized installing easily and fast cutter head, and it is simple in structure, as a preferential embodiment of the present invention, described cutter head is a hexagonal perimeter shape, and described body of rod inner polygon cavity 13 is the hexagon shape also, adopts hexagonal benefit to be to make the cutter head and the body of rod to engage better.
The novel combination type screwdriver that the present invention discloses, the handle of screwdriver has cavity, and no cutter head directly is positioned in this cavity, makes cutter head be difficult for losing; And, the body of rod front portion of screw driver handle is provided with the inner polygon cavity, cutter head is manufactured the polygon peripheral shape, the cutter head and the body of rod can be fastened togather with mating, cavity bottom also has permanent magnet simultaneously, cutter head firmly can be held, realize installing easily and fast cutter head, and simple in structure.
The above only is the specific embodiment of the present invention.Protection scope of the present invention is not limited thereto, and anyly is familiar with those skilled in the art in the technical scope that the present invention discloses, and the variation that can expect easily or replacement all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain that claim was defined.
