[0029] In this embodiment: the electric energy meter is an instrument used to measure electric energy, also known as an electric meter, a fire meter, a kilowatt-hour meter, and refers to an instrument for measuring various electrical quantities, and the wall-mounted electric energy meter is an electric energy meter that is fixed on the wall by a fixed installation method for use; When the existing wall-mounted electric energy meters on the market need to be wired, they usually need to manually strip the end of the wire with a wire stripper, then insert it into the terminal, and then screw the bolt to fix the wire on the terminal to complete the wiring. The whole process not only requires the electrician to strip the insulating outer layer of the terminal one by one, but also requires manually screwing the bolts one by one to fix the terminal. This is not only time-consuming and labor-intensive, but sometimes live work is required under special circumstances. Therefore, a multifunctional wall-mounted electric energy meter is needed.

[0030] In order to facilitate the wiring operation, when using the multifunctional electric energy meter, first insert the wiring wire 3 to be wired into the electric energy meter housing 1, and then continue to insert it between the first pressing plate 21 and the second pressing plate 25 until one end protrudes a short distance outside the first pressing plate 21 and the second pressing plate 25 close to the first movable frame 12. At this time, start the electric telescopic rod 2. After the electric telescopic rod 2 is started, it moves with the first movable frame 12 at the output end. During the movement of the first movable frame 12, it will move with the first spring 13. The elastic force of the first spring 13 is relatively large. The first spring 13 can move with the second movable frame 14 without stretching. As the second movable frame 14 moves, the guide rod 32 corresponding to the second movable frame 14 slides along the first track groove 29. When it continues to slide through the second track groove 30 , so that the two adjacent guide rods 32 are forced to approach each other, and at this time, the two guide rods 32 bring the corresponding third pressure plates 33 to approach each other along the guidance of the first guide rod 34, and finally the two third pressure plates 33 with semicircular contours are pressed together, so that their inner contours form a complete circle, and as the third pressure plates 33 approach, the third pressure plates 33 will press the sleeve 27, and the sleeve 27 will be pressed and the corresponding first pressure plate 21 will be forced to move downward. As the first pressure plate 21 gets closer and closer to the second pressure plate 25, the first pressure plate 21 is forced to slide and adapt along the outer wall of the first fixed block 18 through the first slide groove 20, and the connecting wire 3 between the first pressure plate 21 and the second pressure plate 25 will be tightly clamped therein. Therefore, at this time, the connecting wire 3 will move synchronously with the second mobile frame 14 and the first mobile frame 12 due to being clamped; As the first moving frame 12 and the second moving frame 14 continue to move, the guide rod 32 corresponding to the first moving frame 12 will slide from the fourth track groove 35 to the fifth track groove 36. Due to the track guiding effect of the fifth track groove 36, the two adjacent guide rods 32 are urged to approach each other. At this time, the two guide rods 32 bring the corresponding third pressure plates 33 to approach each other. After approaching, the third pressure plates 33 are urged to approach each other along the guidance of the first guide rod 34, and finally the two third pressure plates 33 with semicircular contours are pressed together, so that their inner contours form a complete circle. In addition, as the third pressure plates 33 approach, the third pressure plates 33 will press the sleeve 27. After being pressed, the sleeve 27 brings the corresponding first pressure plate 21 downward under force. As the first pressure plate 21 gets closer and closer to the second pressure plate 25, the cutting blades 40 between the first pressure plate 21 and the second pressure plate 25 will approach each other and cut the corresponding position of the connecting wire 3. The cutting position is a section of the connecting wire 3 exposed outside the cutting blade 40. As the electric telescopic rod 2 continues to advance, the first mobile frame 12 and the second mobile frame 14 continue to move. At this time, the fixed rod 41 on the outer wall of the second pressure plate 25 corresponding to the first mobile frame 12 follows the movement. When the guide rod 32 corresponding to the first mobile frame 12 continues to slide along the fifth track groove 36 into the sixth track groove 37, the guide rod 32 continues to slide along the sixth track groove 37 into the seventh track groove 38. At this time, continued sliding will cause the fixed rod 41 on the outer wall of the second pressure plate 25 corresponding to the first mobile frame 12 to slide with the ball 42 into the spiral groove 11 on the outer wall of the round frame 10, and as the fixed rod 41 and the ball 42 continue to move, the ball 42 will be prompted to move along the inner wall of the spiral groove 11 and be guided by the spiral groove 11. As the fixed rod 41 and the ball 42 continue to move, the ball 42 and the fixed rod 41 are guided by the spiral groove 11. The guiding effect of the groove 11 is forced to rotate in a circular shape, and the rotation of the fixed rod 41 causes the corresponding second pressure plate 25 to rotate synchronously. The rotation of the second pressure plate 25 causes the second fixed block 22 to rotate together, and the rotation of the second fixed block 22 causes the rotating cylinder 16 to rotate together. While the rotating cylinder 16 rotates along the outer wall of the first movable frame 12, it will twist the torsion spring 17 to facilitate subsequent resetting. At this time, as the rotating cylinder 16 rotates, the first pressure plate 21 also rotates synchronously. The synchronous rotation of the first pressure plate 21 and the second pressure plate 25 maintains the corresponding cutting blade 40 cutting the outer ring of the connecting wire 3, that is, after the two cutting blades 40 press and cut, they rotate and cut in a circular manner, so that the insulating layer at the cutting port can be cut more evenly. It should be noted that due to the action of the torsion spring 17, the notch of the spiral groove 11 aligned with the initial position of the fixed rod 41 and the ball 42 can directly slide into the spiral groove 11; At this time, as the first mobile frame 12 and the second mobile frame 14 continue to move, the guide rod 32 on the outer wall of the second mobile frame 14 will be blocked by the blocking block 46 during the sliding process along the third track groove 31 and cannot continue to move. At this time, the first mobile frame 12 that continues to move will continue to move by stretching the first spring 13. The continued movement of the first mobile frame 12 will prompt the two pressed cutting blades 40 to peel off the already cut insulation layer of the end of the connecting wire 3 from the end of the connecting wire 3. At this time, as the guide rod 32 on the outer wall of the first mobile frame 12 2 continues to slide along the sixth track groove 37, which will cause the guide rod 32 to contact the inclined surface 48 provided on the outer wall of the resistance block 47, thereby causing the resistance block 47 to be forced upward. The resistance block 47 is forced upward to slide along the outer wall of the second guide rod 43, and the third spring 44 is compressed during the movement to facilitate subsequent reset. At this time, the upward movement of the resistance block 46 will release the obstruction of the guide rod 32 corresponding to the second moving frame 14, and the first spring 13 will rebound quickly. The rebound of the first spring 13 brings the second moving frame 14 upward. The movable frame 14 quickly approaches the first movable frame 12, and the second movable frame 14 moves synchronously with the connection wire 3. At this time, the electric telescopic rod 2 is continuously started to cause the first movable frame 12 to continue to move. The guide rod 32 corresponding to the first movable frame 12 will slide from the sixth track groove 37 into the seventh track groove 38. Continuing to slide will release the close clamping state of the two cutting blades 40. At this time, continuing to move the first movable frame 12 and the second movable frame 14 will cause the second movable frame 14 to pass through the first movable frame 1 with the clamped connection wire 3. 2 and expose the stripped end, gradually move toward the round frame 10 and the terminal 5, when the end of the connecting wire 3 is gradually inserted into the terminal 5, the rack 15 will also mesh with the gear 6, the meshing causes the gear 6 to rotate, the rotation of the gear 6 will cause the corresponding bolt 7 to rotate and move downward along the threaded connection of the terminal 5, causing the pressing piece 8 at the end of the bolt 7 to move downward along the wiring hole 9, and the pressing piece 8 gradually presses the end of the connecting wire 3 inserted into the wiring hole 9, so that it is fixed inside the wiring hole 9, completing the entire wiring process; Therefore, the whole process can be completed by simply inserting the connecting wire 3 and starting the electric telescopic rod 2. Finally, the wall-mounted electric energy meter can be installed on the wall as a whole through external tools such as expansion bolts for use.

[0032] The above is only a preferred embodiment 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 technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
