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 adjustable antioverloading screwdriver of a kind of T-shaped load, comprises handle 1, connecting rod 2, guide rail 3, circular hole 4, screw hole 5, trip bolt 6, studs 7, adjusting nut 8, spring 9, slide block 10, Compress Spring 11, base 12, annular groove 13, driver bit 14, 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 both sides of connecting rod 2 are provided with guide rail 3, connecting rod 2 is provided with circular hole 4, the below of guide rail 3 is provided with screw hole 5, trip bolt 6 is provided with in screw hole 5, guide rail 3 is provided with studs 7, studs 7 is provided with adjusting nut 8 and spring 9, slide block 10 and Compress Spring 11 is provided with in connecting rod 2, be provided with base 12 in connecting rod 2, the outer wall of base 12 is provided with annular groove 13, studs 7 after through the guide rail 3 being arranged on connecting rod 2 both sides by spring 9 and adjusting nut 8 fixing on guides 3, base 12 is when entering in connecting rod 2, the screw rod embedding of trip bolt 6 is arranged in the annular groove 13 on base 12 outer wall, and be fixed on by base 12 in connecting rod 2, one end of base 12 is fixedly connected with the top of driver bit 14.
The length of described studs 7 is greater than the drift of described spring 9.
The length of described connecting rod 2 is greater than the length of described guide rail 3.
The length of described connecting rod 2 is greater than the length of described slide block 10.
The length of described connecting rod 2 is greater than the length of described base 12.
The length of described connecting rod 2 is greater than the drift of described Compress Spring 11.
