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, Fig. 3, shown in Fig. 4 and Fig. 5, a kind of bendable antioverloading sleeve screw driver, comprises handle 1, knife bar 2, spring 3, fixed block 4, circular hole 5, screw hole 6, trip bolt 7, base 8, annular groove 9, collet head 10, check lock lever 11, through hole 12, bolt hole 13, set bolt 14, 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 annular groove 9, one end of base 8 is fixedly connected with the top of collet head 10, after one end of base 8 enters the circular hole 5 be arranged in fixed block 4, the screw rod of trip bolt 7 is through the screw hole 6 being arranged on fixed block 4 outside and embedding is arranged in the annular groove 9 of base 8 outside, base 8 is fixed in fixed block 4, the outside of knife bar 2 is provided with check lock lever 11, through hole 12 is provided with in check lock lever 11, the outside of check lock lever 11 is provided with bolt hole 13, set bolt 14 is provided with in bolt hole 13, after knife bar 2 enters the through hole 12 be arranged in check lock lever 11, set bolt 14 is through the bolt hole 13 being arranged on check lock lever 11 outside, check lock lever 11 is fixed on knife bar 2.
The length of described knife bar 2 is greater than the length of described check lock lever 11.
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 length of described fixed block 4.
The length of described knife bar 2 is greater than the height of described base 8.
