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, Fig. 4, shown in Fig. 5 and Fig. 6, the adjustable antioverloading box spanner of the T-shaped load of a kind of telescopic handle, comprises handle 1, connecting rod 2, guide rail 3, circular hole 4, screw hole 5, trip bolt 6, studs 7, spring 8, adjusting nut 9, slide block 10, Compress Spring 11, collet head 12, annular groove 13, Telescopic handle 14, handle socket 15, 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 spring 8 and adjusting nut 9, slide block 10 and Compress Spring 11 is provided with in connecting rod 2, collet head 12 is provided with in connecting rod 2, the outer wall of collet head 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 8 and adjusting nut 9 fixing on guides 3, collet head 12 is when entering in connecting rod 2, the screw rod embedding of trip bolt 6 is arranged in the annular groove 13 on collet head 12 outer wall, collet head 12 is fixed in connecting rod 2, the outside of handle 1 is provided with Telescopic handle 14, handle socket 15 is provided with in Telescopic handle 14, Telescopic handle 14 is provided with screw hole 5, after one end of handle 1 enters the handle socket 15 be arranged in Telescopic handle 14, trip bolt 6 is through the screw hole 5 be arranged on Telescopic handle 14, Telescopic handle 14 is fixed on the outside of handle 1.
