[0025] A moving platform 9 is slidably installed inside the base 5, and a motor 901 is arranged inside the moving platform 9. The motor 901 is fixedly installed on the base 5. The output end of the base 5 is fixedly connected to the threaded column 904. A fixing plate 902 is fixedly installed on the base 5. The fixing plate 902 is arranged on the right side of the motor 901, and a threaded opening is arranged on the fixing plate 902. The threaded column 904 is connected through and through the fixing plate 902. The other end of the threaded column 904 is movably installed in a limiting ring 905 on the left side of a positioning plate 906.

A positioning bar 910 is fixedly installed on the bottom of the inner side of the moving platform 9. The number of positioning bars 910 is There are two, and they are symmetrically installed on the left and right sides of the bottom of the inner side of the moving platform 9. The two positioning strips 910 are provided with tooth rows 909. The moving platform 9 is slidably provided with latch teeth 915. There are two latch teeth 915, and they are symmetrically installed on the left and right sides of the tooth row 909. A connecting column 908 is fixedly installed on the top of the latch tooth 915, and the other end of the connecting column 908 is fixedly installed on the top of the base 5. A positioning plate 2 911 is installed through the protruding position on the left side of the base 5.

A chain opening 907 is provided on the top of the base 5, and is symmetrically arranged with the hinge 913 near the top of the base 5.

[0026] See also Figure 3The working principle of this scheme is as follows: first, the motor 901 drives the threaded column 904, and then the threaded column 904 pushes the positioning plate 1 906 to move to the right, and then the positioning plate 2 911 moves to the right at the same time through the hinge part with the positioning plate 1 906, and then the positioning plate 2 911 and the locking teeth 915 under the positioning plate 1 906 move to the left and right respectively through the connecting column 908 fixedly connected to the positioning plate 2 911 and the positioning plate 1 906, so that the locking teeth 915 are respectively engaged with the tooth rows 909 on the base 5. When the electrical box is not in use, the motor 901 is turned on so that the locking teeth 915 fix the moving platform 9 fixedly connected to the control switch 3, so that the control switch 3 cannot be pressed, thereby achieving the effect of preventing accidental touch.

[0027] A baffle 10 is fixedly installed on the front side of the base 5 near the top. The baffle 10 is "L"-shaped, and one end of the baffle 10 is fixedly connected to the bottom of the control switch 3 through a spring 11.

[0028] A push block 8 is fixedly installed on the other side of the connecting shaft 4, and the push block 8 is slidably installed on the pad 7, and the pad 7 is fixedly installed at a position near the bottom of the inner rear side of the shell 1. A roller 12 is provided on the push block 8, and the roller 12 is rollingly installed on the roller at one end of the pressing plate 13. The other end of the pressing plate 13 is arc-shaped, and an elastic conductive sheet 18 is fixedly installed below the other end of the pressing plate 13. A support frame 14 is fixedly installed on the pad 7, and the pressing plate 13 and the support frame 14 are movably connected by a rolling rod 15 rollingly installed on the support frame 14. A conductive column 16 is fixedly installed on the inner rear side of the shell 1 below the elastic conductive sheet 18, and a conductive column 2 17 is fixedly installed on the inner rear side of the shell 1 on the left side of the conductive column 16.

[0029] See also Figure 5 The working principle of this scheme is as follows: pressing the control switch 3 causes the connecting shaft 4 to push the propulsion block 8 to move downward. Since the upper end of the fixed block 8 is inclined, the roller 12 moves obliquely upward. Therefore, the arc end of the pressing plate 13 presses the elastic conductive sheet 18 to fit tightly against the conductive column 16, thereby avoiding affecting the use of the electrical equipment due to poor contact.

[0030] The working principle of the utility model is as follows: the motor 901 drives the threaded column 904, and then the threaded column 904 pushes the positioning plate 1 906 to move to the right, and then the positioning plate 2 911 moves to the right at the same time through the hinged part with the positioning plate 1 906, and then the positioning plate 2 911 and the latch 915 under the positioning plate 1 906 move to the left and right respectively through the connecting column 908 fixedly connected to the positioning plate 2 911 and the positioning plate 1 906, so that the latch 915 is respectively engaged with the tooth row 909 on the base 5. When the electrical box is not in use, the motor 901 is turned on so that the latch 915 fixes the moving platform 9 fixedly connected to the control switch 3, so that the control switch 3 cannot be pressed; pressing the control switch 3 causes the connecting shaft 4 to push the propulsion block 8 to move downward. Since the upper end of the fixed block 8 is tilted, the roller 12 moves obliquely upward, so the arc end of the pressing plate 13 presses the elastic conductive sheet 18 to fit tightly against the conductive column 16
