[0045] The screw 23 is a hexagon socket screw 23 and is provided with a through hole 24 that penetrates along the length direction of the screw 23. The screw 23 is screwed into the corresponding threaded hole and extends to the inner side of the frame 3, and two inclined limit grooves 25 are symmetrically provided on the inner wall at the end of the screw 23; two positioning columns 26 are symmetrically arranged in the screw head of the screw 23, and the two positioning columns 26 are arranged corresponding to the two limit grooves 25 at the end of the screw 23.

[0046] The slide bar 27 is movably connected to the inside of the through hole 24, and the length of the slide bar 27 is smaller than the length between the end of the limiting groove 25 and the bottom end of the screw head of the screw 23.

[0047] The one-way screw 8 is rotated to make the abutting truncated platform 13 abut against the two clamping plates 31 , and then the clamping plates 31 are separated to both sides and clamped into the limiting grooves 25 on the corresponding sides to lock the screws 23 and the slide rod 27 .

[0048] At the same time, in order to facilitate the insertion or removal of the slide rod 27 during installation or subsequent maintenance, a handle 33 is further provided on the outer side of the limiting plate 28 .

[0049] In actual application, the electric energy meter body 1 is installed in the frame 3 of the lower shell 2, and the line connected to the electric energy meter body 1 is inserted through the corresponding wiring hole from bottom to top and connected to the electric energy meter body 1, and then the auxiliary rotation head 9 is rotated to drive the slide 11 on the one-way screw 8 and the abutting table 13 at the end of the slide 11 to move toward the frame 3 on the corresponding side.

[0050] The upper shell 17 is covered to the outside of the frame 3 and abutted against the lower shell 2, then the screw 23 is screwed into the corresponding threaded hole and the two positioning columns 26 in the screw head of the screw 23 are kept in a horizontal state as much as possible during the screwing, and then the sliding rod 27 is inserted into the through hole 24 on the screw 23, and the two clamping plates 31 at the end of each sliding rod 27 gradually abut against the corresponding abutting round table 13, and then the tool is inserted into the rotation-assisting groove 10 and then rotated.

[0051] Then the plug 14 is sucked by the electromagnet, and then the plug 14 is inserted into the rotation-assisting groove 10 of the rotation-assisting head 9, and then the electromagnet is powered off to lose the attraction of the plug 14, and then the electromagnet is withdrawn, and then the plug 21 is screwed into the insertion hole 20.

[0052] After the upper shell 17 and the lower shell 2 are fixed, the abutting table 13 abuts against the two clamping plates 31, causing the clamping plates 31 to separate to both sides and snap into the limiting grooves 25 on the corresponding sides to lock the screws 23 and the slide bar 27, so that the screw heads of the screws 23 exposed on the outside of the upper shell 17 cannot be rotated, and the slide bar 27 cannot be pulled out by the handle 33, thereby achieving a firm connection between the upper shell 17 and the lower shell 2, preventing others from modifying the module inside the electric energy meter body 1 after separating the two shells to achieve the purpose of stealing electricity, thereby effectively improving the anti-theft performance of the electric energy meter of the present application.

[0054] A plug 21 is screwed into each insertion hole 20, and the rotation-assisting plate is set as a special-shaped plate body. An iron plug 14 is set in the rotation-assisting groove 10. Before use, the plug 21 needs to be unscrewed first, and then the plug 14 is sucked out of the rotation-assisting groove 10 by an electromagnet before a tool can be used to insert the tool into the rotation-assisting groove 10 and then the one-way screw 8 is twisted. That is, through the multiple obstacles set, it is difficult for others to separate the upper shell 17 from the lower shell 2, thereby improving the anti-theft performance of the electric energy meter of the present application.

[0055] The above is only a preferred implementation of the patent of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the patent of the present invention.
