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, shown in Fig. 4 and Fig. 5, a kind of load adjustable antioverloading formula electroprobe, comprises handle 1, knife bar 2, screw hole 3, trip bolt 4, circular hole 5, spring 6, base 7, first order annular groove 8, second level annular groove 9, driver bit 10, external screw thread 11, neon tube 12, crown cap 13, internal thread 14, it is characterized in that: one end of described handle 1 is provided with knife bar 2, the other end of handle 1 is provided with external screw thread 11, circular hole 5 is provided with in handle 1, one end of handle 1 is fixedly connected with one end of knife bar 2, the other end of handle 1 is connected with crown cap 13 by external screw thread 11, circular hole 5 is provided with in knife bar 2, knife bar 2 is provided with screw hole 3, trip bolt 4 is provided with in screw hole 3, be arranged in the circular hole 5 in knife bar 2 and be provided with spring 6 and base 7, the outer wall of base 7 is provided with first order annular groove 8 and second level annular groove 9, one end of base 7 is fixedly connected with the top of driver bit 10, spring 6 and base 7 are after entering the circular hole 5 be arranged in knife bar 2, trip bolt 4 embeds in the first order annular groove 8 or second level annular groove 9 that are arranged on base 7 outer wall afterwards through the screw hole 3 be arranged on knife bar 2, spring 6 and base 7 are fixed in knife bar 2, spring 6 and neon tube 12 is provided with in handle 1, spring 6 and neon tube 12 are after entering the circular hole 5 be arranged in handle 1, crown cap 13 is connected with the external screw thread 11 being arranged on handle 1 end, spring 6 and neon tube 12 are fixed in handle 1, internal thread 14 is provided with in crown cap 13.
