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, the T-shaped antioverloading screwdriver of a kind of bendable, comprises handle 1, connecting rod 2, spring 3, fixed block 4, circular hole 5, screw hole 6, trip bolt 7, base 8, annular groove 9, driver bit 10, it is characterized in that: one end of described connecting rod 2 is fixedly connected with the middle part of handle 1 is vertical, the other end of connecting rod 2 is provided with spring 3, one end of spring 3 is fixedly connected with one end of connecting rod 2, the other end of spring 3 is fixedly connected with the top of fixed block 4, circular hole 5 is provided with in fixed block 4, base 8 is provided with in circular hole 5, the outer wall of base 8 is provided with annular groove 9, fixed block 4 is provided with screw hole 6, trip bolt 7 is provided with in screw hole 6, be provided with spring 3 in fixed block 4, after one end of base 8 embeds the circular hole 5 be arranged in fixed block 4, the screw rod of trip bolt 7 is through the screw hole 6 be arranged on fixed block 4 and embed in the annular groove 9 that is arranged on base 8 outer wall, be fixed on by base 8 in fixed block 4, one end of base 8 is fixedly connected with the top of driver bit 10.
The height of described fixed block 4 is greater than the height of described base 8.
The height of described base 8 is greater than the width of described annular groove 9.
The width of described annular groove 9 is greater than the diameter of the screw rod of described trip bolt 7.
The length of described connecting rod 2 is greater than the drift of described spring 3.
The length of described connecting rod 2 is greater than the height of described fixed block 4.
