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, one can bending antioverloading sleeve electroprobe, 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, through hole 11, external screw thread 12, neon tube 13, crown cap 14, internal thread 15, 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, through hole 11 is provided with in handle 1, handle 1 is provided with external screw thread 12, spring 3 and neon tube 13 is provided with in through hole 11, external screw thread 12 is provided with crown cap 14, internal thread 15 is provided with in crown cap 14, spring 3 and neon tube 13 are after entering the through hole 11 be arranged in handle 1, crown cap 14 is connected with the external screw thread 12 being arranged on handle 1 end, spring 3 and neon tube 13 are fixed in handle 1.
The length of described spring 3 is greater than the length of described neon tube 13.
