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, Fig. 2, shown in Fig. 3 and Fig. 4, one can the adjustable antioverloading screwdriver of bending load, comprises handle 1, knife bar 2, spring 3, fixed block 4, circular hole 5, screw hole 6, trip bolt 7, base 8, first order annular groove 9, second level annular groove 10, driver bit 11, it is characterized in that: one end of described handle 1 is provided with knife bar 2, one end of knife bar 2 is fixedly connected with one end of handle 1, 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 one end of fixed block 4, circular hole 5 is provided with in fixed block 4, the outside of fixed block 4 is provided with screw hole 6, trip bolt 7 is provided with in screw hole 6, spring 3 and base 8 is provided with in circular hole 5, the outside of base 8 is provided with first order annular groove 9 and second level annular groove 10, one end of base 8 is fixedly connected with the top of driver bit 11, after one end of base 8 enters the circular hole 5 be arranged in fixed block 4, the screw rod of trip bolt 7 also embed through the screw hole 6 being arranged on fixed block 4 outside be arranged on base 8 outside first order annular groove 9 or second level annular groove 10 in, base 8 is fixed in fixed block 4.
The length of described knife bar 2 is greater than the length of described fixed block 4.
The length of described knife bar 2 is greater than the drift of described spring 3.
The length of described knife bar 2 is greater than the height of described base 8.
The length of described knife bar 2 is greater than the length of described handle 1.
The diameter of described knife bar 2 is greater than the external diameter of described spring 3.
The diameter of described circular hole 5 is greater than the diameter of described base 8.
The diameter of described circular hole 5 is greater than the external diameter of described spring 3.
The length of described fixed block 4 is greater than the height of described base 8.
The height of described base 8 is greater than the height of described driver bit 11.
The surface of described handle 1, knife bar 2, spring 3, fixed block 4, trip bolt 7, base 8, driver bit 11 is through the concentrated sulfuric acid or red fuming nitric acid (RFNA) Passivation Treatment at normal temperatures, 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 11 aimed at and embed in the groove of screw that needs to be tightened and to unscrew, simultaneously to handle 1 apply lateral pressure by spring 3 bending and turning handle 1 can tighten screw and unscrew.
When moment is greater than the frictional force at spring 3 pairs of base 8 tops, base 8 just can skid in fixed block 4, now increases moment in any case and all can not tighten screw and unscrew, thus can effectively prevent because moment is excessive and cause screw to damage.
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.
