[0023] An embodiment of the present invention provides an auxiliary tool for a grounding switch locking plate, comprising a force rod 1, a tongue piece 2 and a bracket 3; the force rod 1 provides a force point for the staff, the tongue piece 2 fixes the top of the locking plate, and the bracket 3 fixes the bottom of the locking plate.
[0024] Specifically, a connecting transition portion 11 is provided at one end of the force adding rod 1, and the connecting transition portion 11 is fixedly connected to the bracket 3 based on a fixing screw 111, and the bracket 3 and the force adding rod 1 are connected together based on the connecting transition portion 11; the connecting transition portion 11 is provided with a connecting through hole between the bracket 3 and the force adding rod 1, and the connecting transition portion 11 can be connected to other components based on the connecting through hole;
[0025] The tongue piece 2 includes a first connecting plate 21 and a second connecting plate 22. The first connecting plate 21 is connected to the connecting transition portion 11 based on the connecting through hole. The second connecting plate 22 is vertically arranged on one end of the first connecting plate 21, and the second connecting plate 22 faces the bracket. The first connecting plate 21 and the second connecting plate 22 form an L-shaped tongue piece, and the top of the locking plate is fixed based on the L-shaped tongue piece 2.
[0026] The bracket 3 includes a bracket connecting plate 31, a first fixing plate 311 and a second fixing plate 312. The bracket 3 is connected to the force rod 1 based on the bracket connecting plate 31, and the bottom of the locking plate is fixed by the first fixing plate 311 and the second fixing plate 312; the bracket connecting plate 31 is fixed to the connecting transition portion based on the fixing screw 111, one end of the bracket connecting plate 31 is provided with the first fixing plate 311, the first fixing plate 311 is provided with a first knob 3111, the second fixing plate 312 is provided at the other end of the bracket connecting plate 31, and the second fixing plate is provided with a second knob 3121. Based on adjusting the height of the first knob 3111 and the second knob 3121, the first fixing plate 311 and the second fixing portion 312 can firmly fix the bottom of the locking plate.
[0027] Furthermore, the first fixing plate 311 and the second fixing plate 312 are U-shaped metal plates. Based on the fact that the first fixing plate 311 and the second fixing plate 312 are U-shaped fixing plates, the bracket 3 can extend into the bottom of the locking plate and be fixed.
[0028] Furthermore, one side wing of the first fixing plate 311 is arranged on one end of the bracket connecting plate 31, and a first knob through hole is arranged on the other side wing of the first fixing plate 311. The first knob 3111 is fixed to the first fixing plate based on the first knob through hole, and the first knob 3111 can be fixed to the first fixing plate 311 based on the first knob through hole, and the height of the first knob 3111 can be adjusted.
[0029] Furthermore, one side wing of the second fixing plate 312 is arranged at the other end of the bracket connecting plate 31, and a second knob through hole 3121 is arranged on the other side wing of the second fixing plate 312. The second knob 3121 is fixed to the second fixing plate 312 based on the second knob through hole. The second knob 3121 can be fixed to the second fixing plate 312 based on the second knob through hole, and the height of the second knob 3121 can be adjusted.
[0030] Furthermore, the first knob and the second knob are butterfly-type knobs.

[0031] Furthermore, a hand guard 12 is provided on the force adding rod, and the hand guard 12 is an anti-slip rubber hand guard. The anti-slip rubber hand guard 12 increases the friction between the force adding rod 1 and the human hand, thereby ensuring that the auxiliary tool will not slip during use.
[0032] Furthermore, the force rod 1, the bracket 3 and the tongue piece 2 are made of stainless steel. The force rod 1, the tongue piece 2 and the bracket 3 made of stainless steel can effectively resist oxidation and rust, and can greatly extend the service life of the auxiliary tool.
[0033] The embodiment of the present invention provides an auxiliary tool for the grounding knife switch locking plate. The auxiliary tool is based on the first fixing plate and the second fixing plate on the bracket, extends into the gap at the bottom of the locking plate, and then the first knob and the second knob are twisted to adjust the height of the locking plate, and then an upward force is applied to the force rod to lift the L-shaped tongue piece. When the force rod is lifted until the L-shaped tongue piece presses the top of the fixed locking plate, downward pressure is applied to the force rod, and the L-shaped tongue piece drives the locking plate to move downward and open. In this way, the grounding knife switch locking plate is solved. The process of opening the grounding knife switch locking plate is laborious, easy to get stuck and deformed, and the opening process is cumbersome.
[0034] In addition, the auxiliary tools provided in the embodiments of the present invention are introduced in detail above.
