[0033] 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.

[0034] In order to facilitate the wiring operation more conveniently, when using this electricity meter, first insert the connecting wire 3 to be wired into the electricity meter housing 1, and then continue to pass through 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 near the first moving frame 12. At this time, start the electric telescopic rod 2. After the electric telescopic rod 2 starts, it drives the first moving frame 12 at the output end to move. During the movement of the first moving frame 12, it will drive the first spring 13 to move together. And the elastic force of the first spring 13 is relatively large. When the first spring 13 is not stretched, it can drive the second moving frame 14 to move together. As the second moving frame 14 moves, the corresponding guide rod 32 of the second moving frame 14 slides along the first track groove 29. When continuing to slide through the second track groove 30, the adjacent two guide rods 32 are forced to approach each other. At this time, the two guide rods 32 drive the corresponding third pressing plates 33 to approach each other along the guidance of the first guide rod 34, and finally the third pressing plates 33 with semicircular contours are pressed together, and their inner contours form a complete circle. And, as the third pressing plates 33 approach, the third pressing plates 33 will press on the sleeve 27. After the sleeve 27 is pressed, it drives the corresponding first pressing plate 21 to move downward under force. As the first pressing plate 21 gets closer and closer to the second pressing plate 25, it prompts the first pressing plate 21 to slide along the outer wall of the first fixed block 18 through the first chute 20 to adapt, and will tightly clamp the connecting wire 3 between the first pressing plate 21 and the second pressing plate 25. Therefore, at this time, since the connecting wire 3 is clamped, it will move synchronously with the second moving frame 14 and the first moving frame 12; As the first moving frame 12 and the second moving frame 14 continue to move, at this time, the guide rod 32 corresponding to the first moving frame 12 will slide from the fourth track groove 35 into the fifth track groove 36. Due to the guiding effect of the fifth track groove 36, it prompts the adjacent two guide rods 32 to approach each other. At this time, the two guide rods 32 drive the corresponding third pressing plates 33 to approach each other. After approaching, it prompts the third pressing plates 33 to approach each other along the guidance of the first guide rod 34, and finally the third pressing plates 33 with semicircular contours are pressed together, and their inner contours form a complete circle. And, as the third pressing plates 33 approach, the third pressing plates 33 will press on the sleeve 27. After the sleeve 27 is pressed, it drives the corresponding first pressing plate 21 to move downward under force. As the first pressing plate 21 gets closer and closer to the second pressing plate 25, the cutting blades 40 between the first pressing plate 21 and the second pressing plate 25 will approach each other at this time, and cut the corresponding position of the connecting wire 3. The cutting position is at a section of the connecting wire 3 that is exposed outside the cutting blades 40; With the continuous advancement of the electric telescopic rod 2, the first moving frame 12 and the second moving frame 14 are driven to continue moving. At this time, during the movement of the fixing rod 41 on the outer wall of the second pressing plate 25 corresponding to the first moving frame 12, when the guide rod 32 corresponding to the first moving frame 12 continues to slide along the fifth track groove 36 into the sixth track groove 37, and then when the guide rod 32 continues to slide along the sixth track groove 37 into the seventh track groove 38, further sliding at this time will cause the fixing rod 41 on the outer wall of the second pressing plate 25 corresponding to the first moving frame 12 to drive the ball 42 to slide into the spiral groove 11 on the outer wall of the circular frame 10. And with the continuous movement of the fixing rod 41 and the ball 42, it will cause the ball 42 to move along the inner wall of the spiral groove 11, and under the guidance of the spiral groove 11, with the continuous movement of the fixing rod 41 and the ball 42, it makes the ball 42 and the fixing rod 41 rotate circularly under the guiding action of the spiral groove 11. The rotation of the fixing rod 41 drives the corresponding second pressing plate 25 to rotate synchronously. The rotation of the second pressing plate 25 will drive the second fixing block 22 to rotate together. The rotation of the second fixing block 22 will drive the rotating cylinder 16 to rotate together. While the rotating cylinder 16 rotates along the outer wall of the first moving frame 12, it will twist the torsion spring 17 for subsequent reset. At this time, with the rotation of the rotating cylinder 16, the first pressing plate 21 is also driven to rotate synchronously. The synchronous rotation of the first pressing plate 21 and the second pressing plate 25 maintains the cutting of the corresponding cutting blade 40 against the outer circle of the wire 3. That is, after the two cutting blades 40 press and cut, they rotate and cut, which can more evenly cut the insulating layer at the cutting port. It should be noted that due to the action of the torsion spring 17, the initial positions of the fixing rod 41 and the ball 42 are aligned with the notch of the spiral groove 11 and can directly slide into the spiral groove 11; At this time, as the first moving frame 12 and the second moving frame 14 continue to move, the guide rod 32 on the outer wall of the second moving 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 moving frame 12 that continues to move will continue to move by stretching the first spring 13. The continuous movement of the first moving frame 12 will cause the two pressed cutting blades 40 to strip and drop the insulating layer at the end of the cut 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 moving frame 12 continues to slide along the sixth track groove 37, it will cause the guide rod 32 to contact the inclined surface 48 opened on the outer wall of the contact block 47, thereby causing the contact block 47 to be stressed upward. The upward force on the contact block 47 drives the lifting plate 45 and the blocking block 46 to slide upward 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 blocking block 46 will release the block on the guide rod 32 corresponding to the second moving frame 14. At this time, the first spring 13 rebounds rapidly, and the rebound of the first spring 13 drives the second moving frame 14 to quickly approach the first moving frame 12. At this time, the second moving frame 14 drives the connecting wire 3 to move synchronously. And at this time, the electric telescopic rod 2 is started continuously, so that the first moving frame 12 continues to move. The guide rod 32 corresponding to the first moving frame 12 will slide from the sixth track groove 37 into the seventh track groove 38, and the continuous sliding will release the close clamping state of the two cutting blades 40. At this time, when the first moving frame 12 and the second moving frame 14 continue to move, it will cause the second moving frame 14 to drive the clamped connecting wire 3 to pass through the first moving frame 12 and expose the stripped end, and gradually move toward the direction of the circular frame 10 and the terminal 5. When the end of the connecting wire 3 is gradually inserted into the terminal 5, at this time, the rack 15 will also engage with the gear 6, and the engagement causes the gear 6 to rotate. The rotation of the gear 6 will cause the corresponding bolt 7 to rotate 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 to fix it inside the wiring hole 9, completing the entire wiring process; Therefore, the whole process only needs the operator to insert the connecting wire 3 and then start the electric telescopic rod 2 to complete. Finally, the wall-mounted watt-hour meter can be installed on the wall as a whole by external tools such as expansion bolts for use.
