Description
Technical field
The utility model relates to a kind of screwdriver, and specifically a kind of bending dual-purpose type screwdriver, belongs to machine tool technical field.
Background technology
Screwdriver is that a kind of being used for twists screw with the instrument forcing it in place, usually a thin sphenocephaly is had, in the line of rabbet joint that can insert screw cap or recess, screwdriver is generally made up of handle and the first-class multiple component of screwdriver, is specially adapted to tighten and unscrew the screw of the very narrow or very depths of caving in, residing space.
Often need to use screwdriver tighten screw and unscrew in machine work.Because the structure of current widely used screwdriver in production and life is all generally fixing, certain operating radius is needed when the existing screwdriver of use to be tightened the screw being in the narrow location such as corner and unscrewed, cause normally using screwdriver tighten the screw being in the narrow location such as corner and unscrew, therefore, in the urgent need to a kind of screwdriver that can tighten the screw being in the narrow location such as corner and unscrew.
Summary of the invention
The technical problems to be solved in the utility model is: provide a kind of structure simple, easy to use, and can pass through the knife bar bending of screwdriver thus the bending dual-purpose type screwdriver that can tighten the screw being in the narrow location such as corner and unscrew.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of bending dual-purpose type screwdriver, comprise handle, knife bar, spring, driver bit, check lock lever, through hole, screw hole, trip bolt, it is characterized in that: one end of described handle is fixedly connected with one end of knife bar, the other end of knife bar is fixedly connected with one end of spring, the other end of spring is fixedly connected with the top of driver bit, knife bar is provided with check lock lever, through hole is provided with in check lock lever, one end of check lock lever is provided with screw hole, trip bolt is provided with in screw hole, check lock lever is fixed on knife bar by the screw hole be arranged on check lock lever by trip bolt.
The length of described knife bar is greater than the length of described check lock lever.
The length of described knife bar is greater than the length of described handle.
The diameter of the described through hole be arranged in check lock lever is greater than the diameter of described knife bar.
The diameter of the described through hole be arranged in check lock lever is greater than the external diameter of described spring.
The diameter of the described through hole be arranged in check lock lever is greater than the diameter at described driver bit top.
The diameter of described knife bar is greater than the external diameter of described spring.
The diameter at described driver bit top is greater than the external diameter of described spring.
The length of described knife bar is greater than the drift of described spring.
Described spring is cylindrical helical spring, and object is transmitting torque, thus the object that realization will be tightened the screw being in the narrow location such as corner and unscrew while knife bar bending.
The surface of described handle, knife bar, spring, driver bit, check lock lever, trip bolt is through concentrated sulfuric acid Passivation Treatment, and object improves the resistance to corrosion of screwdriver, to adapt to the severe working environment of various complexity.
Compared with prior art, the utility model has following beneficial effect: structure is simple, easy to use, can pass through the knife bar bending of screwdriver thus the screw being in the narrow location such as corner be tightened and unscrews, be conducive to improving the operating efficiency of tightening and unscrewing the screw being in the narrow location such as corner.

Fig. 2 is another perspective view of the present utility model.
Fig. 3 is stereochemical structure exploded perspective view of the present utility model.
In figure: 1-handle, 2-knife bar, 3-spring, 4-driver bit, 5-check lock lever, 6-through hole, 7-screw hole, 8-trip bolt.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As Fig. 1, shown in Fig. 2 and Fig. 3, a kind of bending dual-purpose type screwdriver, comprise handle 1, knife bar 2, spring 3, driver bit 4, check lock lever 5, through hole 6, screw hole 7, trip bolt 8, it is characterized in that: one end of described handle 1 is fixedly connected with one end of knife bar 2, the other end of knife bar 2 is fixedly connected with one end of spring 3, the other end of spring 3 is fixedly connected with the top of driver bit 4, knife bar 2 is provided with check lock lever 5, through hole 6 is provided with in check lock lever 5, one end of check lock lever 5 is provided with screw hole 7, trip bolt 8 is provided with in screw hole 7, check lock lever 5 is fixed on knife bar 2 by the screw hole 7 be arranged on check lock lever 5 by trip bolt 8.
The length of described knife bar 2 is greater than the length of described check lock lever 5.
The length of described knife bar 2 is greater than the length of described handle 1.
The diameter of the described through hole 6 be arranged in check lock lever 5 is greater than the diameter of described knife bar 2.
The diameter of the described through hole 6 be arranged in check lock lever 5 is greater than the external diameter of described spring 3.
The diameter of the described through hole 6 be arranged in check lock lever 5 is greater than the diameter at described driver bit 4 top.
The diameter of described knife bar 2 is greater than the external diameter of described spring 3.
The diameter at described driver bit 4 top is greater than the external diameter of described spring 3.
The length of described knife bar 2 is greater than the drift of described spring 3.
Described spring 3 is cylindrical helical spring, and object is transmitting torque, thus the object that realization will be tightened the screw being in the narrow location such as corner and unscrew while knife bar 2 bending.
The surface of described handle 1, knife bar 2, spring 3, driver bit 4, check lock lever 5, trip bolt 8 is through concentrated sulfuric acid Passivation Treatment, and object improves the resistance to corrosion of screwdriver, to adapt to the severe working environment of various complexity.
As shown in Figure 1, when needing tighten the screw being in the narrow location such as corner and unscrew, first driver bit 4 is aimed at the screw needing to be tightened and to unscrew, lateral pressure is applied by spring 3 bending to handle 1, driver bit 4 is embedded in the groove of screw that needs to be tightened and to unscrew simultaneously, rotary handle 1 can be tightened the screw being in the narrow location such as corner and unscrew, thus the object that realization is tightened the screw being in the narrow location such as corner and unscrewed.
As shown in Figure 2, when not needing tighten the screw being in the narrow location such as corner and unscrew, first unscrew trip bolt 8, then check lock lever 5 is stretched out along knife bar 2 and the top of driver bit 4 is inserted in check lock lever 5, screw trip bolt 8 simultaneously and get final product fixing and locking bar 5, now applying lateral pressure to handle 1 just can not spring 3 bending, finally driver bit 4 is aimed at the screw that needs to be tightened and to unscrew and turning handle 1 can be tightened screw and unscrew.
The above is preferred embodiment of the present utility model; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the utility model principle; can also make some improvements and modifications, these improvements and modifications are also considered as protection domain of the present utility model.
