In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is: the adjustable antioverloading box spanner of a kind of telescopic handle load, comprise handle, connecting rod, circular hole, screw hole, trip bolt, spring, collet head, first order annular groove, second level annular groove, Telescopic handle, handle socket, it is characterized in that: one end of described connecting rod is fixedly connected with the middle part of handle is vertical, connecting rod is provided with circular hole, the lower end of connecting rod is provided with screw hole, trip bolt is provided with in screw hole, spring and collet head is provided with in circular hole, collet head is provided with first order annular groove and second level annular groove, second level annular groove is arranged on the top of first order annular groove, trip bolt embeds in first order annular groove or second level annular groove after through the screw hole being arranged on connecting rod lower end, the outside of handle is provided with Telescopic handle, handle socket is provided with in Telescopic handle, Telescopic handle is provided with screw hole, after one end of handle enters the handle socket be arranged in Telescopic handle, trip bolt is through the screw hole be arranged on Telescopic handle, Telescopic handle is fixed on the outside of handle.
The length of described handle is greater than the length of described Telescopic handle.
The drift of described spring is greater than the length of described collet head.
The profile of described handle, connecting rod is cylindrical structural.
Described trip bolt embeds in first order annular groove or second level annular groove after through the screw hole being arranged on connecting rod lower end, and effect is fixed in circular hole by collet head.
The width of described first order annular groove and second level annular groove is greater than the diameter of the screw rod of described trip bolt.
The profile of described collet head is the cylindrical structural being provided with first order annular groove and second level annular groove.
The drift of described spring is greater than the length of described connecting rod.
The length of described connecting rod is greater than the length of described collet head.
Compared with prior art, the utility model has following beneficial effect: structure is simple, easy to use, when dismantling bolt, nut and being fastening, when spanner reaches certain limit to bolt, nut applied force square, collet head just can skid in connecting rod, thus can effectively prevent because moment is excessive and cause bolt, nut to damage, and the size of the maximum moment of its load can be changed, so not only use cost can be reduced, and the labour intensity of workmen can be reduced, be conducive to increasing work efficiency.

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 adjustable antioverloading box spanner of a kind of telescopic handle load, comprises handle 1, connecting rod 2, circular hole 3, screw hole 4, trip bolt 5, spring 6, collet head 7, first order annular groove 8, second level annular groove 9, Telescopic handle 10, handle socket 11, it is characterized in that: one end of described connecting rod 2 is fixedly connected with the middle part of handle 1 is vertical, connecting rod 2 is provided with circular hole 3, the lower end of connecting rod 2 is provided with screw hole 4, trip bolt 5 is provided with in screw hole 4, spring 6 and collet head 7 is provided with in circular hole 3, collet head 7 is provided with first order annular groove 8 and second level annular groove 9, second level annular groove 9 be arranged on first order annular groove 8 above, trip bolt 5 embeds in first order annular groove 8 or second level annular groove 9 after through the screw hole 4 being arranged on connecting rod 2 lower end, the outside of handle 1 is provided with Telescopic handle 10, handle socket 11 is provided with in Telescopic handle 10, Telescopic handle 10 is provided with screw hole 4, after one end of handle 1 enters the handle socket 11 be arranged in Telescopic handle 10, trip bolt 5 is through the screw hole 4 be arranged on Telescopic handle 10, Telescopic handle 10 is fixed on the outside of handle 1.
