Description
Technical field
The utility model relates to a kind of screwdriver, and specifically the T-shaped screwdriver of a kind of bending dual-purpose type, 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 connecting rod bending of screwdriver thus the T-shaped screwdriver of bending dual-purpose type 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: the T-shaped screwdriver of a kind of bending dual-purpose type, comprise handle, connecting rod, spring, driver bit, check lock lever, through hole, screw hole, trip bolt, it is characterized in that: described handle, connecting rod, check lock lever is cylindrical structural, one end of connecting rod is fixedly connected with the middle part of handle is vertical, the lower end of connecting rod is provided with spring, the lower end of spring is provided with driver bit, the other end of connecting rod is fixedly connected with one end of spring, the other end of spring is fixedly connected with the top of driver bit, connecting rod is provided with check lock lever, through hole is provided with in check lock lever, the upper end of check lock lever is provided with screw hole, trip bolt is provided with in screw hole, check lock lever is fixed on connecting rod by the screw hole being arranged on check lock lever upper end by trip bolt.
The length of described check lock lever is greater than the drift of described spring.
The diameter of the described through hole be arranged in check lock lever is greater than the diameter of described connecting rod.
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 connecting rod 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 connecting rod 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 connecting rod bending.
Compared with prior art, the utility model has following beneficial effect: structure is simple, easy to use, can pass through the connecting rod 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.

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, the T-shaped screwdriver of a kind of bending dual-purpose type, comprise handle 1, connecting rod 2, spring 3, driver bit 4, check lock lever 5, through hole 6, screw hole 7, trip bolt 8, it is characterized in that: described handle 1, connecting rod 2, check lock lever 5 is cylindrical structural, one end of connecting rod 2 is fixedly connected with the middle part of handle 1 is vertical, the lower end of connecting rod 2 is provided with spring 3, the lower end of spring 3 is provided with driver bit 4, the other end of connecting rod 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, connecting rod 2 is provided with check lock lever 5, through hole 6 is provided with in check lock lever 5, the upper 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 connecting rod 2 by the screw hole 7 being arranged on check lock lever 5 upper end by trip bolt 8.
The length of described check lock lever 5 is greater than the drift of described spring 3.
The diameter of the described through hole 6 be arranged in check lock lever 5 is greater than the diameter of described connecting rod 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 connecting rod 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 connecting rod 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 connecting rod 2 bending.
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 connecting rod 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, and finally being embedded by driver bit 4 needs in the groove of the screw being tightened and unscrewing 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.
