[0023] Please refer to Figure 1 and Figure 2 , Figure 1The utility model discloses a structure schematic drawing of the maintenance tool for preventing the indication rod from being blocked of the switch machine, Figure 2 It is the use schematic drawing of the maintenance tool for preventing the indication rod from being blocked of the switch machine, a maintenance tool for preventing the indication rod from being blocked of the switch machine, including operating handle and adjusting piece, adjusting piece installs in operating handle middle part, and with operating handle vertical setting, the recess is set up in the middle part of the one end of adjusting piece away from operating handle.

[0024] The inside detection rod gap adjustment work of switch machine generally involves detection rod and indication rod, one end of detection rod is equipped with fork joint, the installation shaft is equipped in fork joint, one end of indication rod is equipped with indication rod joint, the other end is equipped with indication rod nut, indication rod joint is set on the installation shaft in fork joint, such as Figure 3 Before adjusting gap, holding operating handle, inserting adjusting piece between fork joint and indication rod joint gap, and making the installation shaft of fork joint insert into the recess of adjusting piece, so that adjusting piece is installed between fork joint and indication rod joint gap, the contact surface of adjusting piece two sides respectively sticks to fork joint and indication rod joint, prevent indication rod nut from appearing indication rod joint and fork joint extrusion under stress when fastening, and the contact area between adjusting piece and fork joint and indication rod joint is big, avoid the phenomenon of uneven stress and not level, further prevent the phenomenon of blocking, and directly inserting adjusting piece between fork joint and indication rod joint gap can be fixed, without hand holding this maintenance tool, single person can complete adjusting gap work, after fastening indication rod nut, adjusting piece is extracted through operating handle.

[0025] Because the thickness of indication rod joint produced by different manufacturers can be different, in an embodiment, the number of adjusting piece is multiple, the thickness of multiple adjusting pieces is different, and each adjusting piece is selectively installed on operating handle. According to the thickness of different indication rod joints, the adjusting piece with appropriate thickness can be selected to adjust gap work according to the need, so that the maintenance tool for preventing the indication rod from being blocked of the switch machine of the utility model can be applicable to the gap adjustment work of multiple switch machines.

[0026] In an embodiment, any two adjusting pieces are selectively installed on both sides of the middle part of operating handle. The adjusting piece can be installed on both sides of operating handle, that is, two adjusting pieces with different thicknesses can be installed on operating handle, so that the maintenance tool for preventing the indication rod from being blocked of the switch machine of the utility model can be applicable to the gap adjustment work of two different thicknesses of indication rod joints in ordinary times, and the frequency of replacing adjusting piece is reduced.

[0027] In an embodiment, the operating handle is provided with a plurality of first through holes and a plurality of second through holes, the adjusting sheet is provided with a plurality of third through holes, the plurality of third through holes correspond to the plurality of first through holes one by one respectively, and the plurality of third through holes correspond to the plurality of second through holes one by one respectively, the adjusting sheet is installed on the operating handle by screwing nuts after the adjusting sheet passes through the corresponding third through holes and the first through holes through bolts, or the adjusting sheet is installed on the operating handle by screwing nuts after the adjusting sheet passes through the corresponding third through holes and the second through holes through bolts.
