[0032] The working principle of this embodiment is as follows: when using this portable digital power meter, after completing the measurement, when it needs to be carried, the armrest 302 is pulled to drive the box body 301 to rotate around the first rotating shaft 311 through the first rotating shaft connecting block 312, and the first shaft sleeve 313 is driven to rotate around the first rotating shaft 311 by the second rotating shaft connecting block 315. At this time, the symmetrically arranged box body 301 drives the second shaft sleeve 314 to rotate around the first rotating shaft 311 through the second rotating shaft connecting block 315. When the box body 301 contacts the symmetrically arranged box body 301, it is lifted by pushing the sliding block 303, and then the first block 304 is pushed to move along the outer surface of the box body 301, and when it moves to the left side of the stopper 307 through the first slot connecting block 305 and the second slot connecting block 306, the force pushing the sliding block 303 is lost, and the sliding block 303 is pushed by the first spring 309 to move downward along the first slot 308, and the sliding block 3 03, the right side surface of the first clamping block 304 contacts the left side surface of the box body 301 and the symmetrically arranged box body 301 is fixed. The fixing component 3001 is fixed on the front and rear sides and is continuously fixed by the first spring 309, so that it will not open due to vibration during the carrying process. At this time, the first hydraulic pump 403 and the second hydraulic pump 406 are started, and the first push block 404 and the second push block 405 are pushed through the output end, and the first push block 404 and the second push block 405 are driven to move downward, so that the push plate 408 moves downward, and the first butterfly spring 409 moves downward, and the movement is transferred to the second butterfly spring 410 through the power meter body 1. The second butterfly spring 410 is compressed downward, and the first baffle 411 and the second baffle 412 move upward. At this time, the first butterfly spring 409 and the second butterfly spring 410 cooperate to achieve clamping and vibration absorption in the vertical direction.

[0033] Example 2: Please refer to Figure 8-Figure 9 On the basis of the first embodiment, the present invention provides a technical solution: the horizontal stabilizing mechanism 5 includes a first leaf spring 501, the outer surface of the first leaf spring 501 is fixedly connected to the inner wall of the box body 301, the top of the first leaf spring 501 is fixedly connected to a fourth connecting block 502, the top of the fourth connecting block 502 is fixedly connected to a second leaf spring 503, the top of the second leaf spring 503 is fixedly connected to a fifth connecting block 504, the top of the fifth connecting block 504 is fixedly connected to a first circular column 505, a second circular column 509, a second spring 506 and a third spring 510, the bottom plate of the second spring 506 and the third spring 510 is fixedly connected to a sixth connecting block 507, the top of the sixth connecting block 507 is fixedly connected to a third clamping block 508, the inner wall of the box body 301 is fixedly connected to a fourth clamping block 511, and the horizontal stabilizing mechanism 5 is symmetrically arranged in two groups on the inner wall of the box body 301; The length of the components of the horizontal stabilization mechanism 5 except the fourth clamping block 511 is the same as the length of the side clamping slot of the power meter body 1. The side of the fourth clamping block 511 is in contact with the surface of the power meter body 1. The horizontal stabilization mechanism 5 is arranged to cooperate with the vertical stabilization mechanism 4, and the horizontal limit and front and rear limit of the power meter are realized through the second clamping block 401 and the fourth clamping block 511. The horizontal and front and rear vibrations during carrying are absorbed through the second spring 506, the third spring 510, the first leaf spring 501 and the second leaf spring 503, and a high level of protection for the power meter is achieved together, so that the power meter can resist interference from various vibrations during carrying, and provide users with a reliable measurement tool.

[0034] The working principle of this embodiment is as follows: the process of the first embodiment is supplemented to achieve stability in the horizontal direction. At this time, the third clamping block 508 is driven by the rotation of the box body 301 to contact the side clamping slot of the power meter body 1. The third clamping block 508 transfers the vibration to the first leaf spring 501 through the sixth connecting block 507. The first leaf spring 501 is compressed and absorbs part of the vibration, and transfers the vibration to the second leaf spring 503 through the fourth connecting block 502. The second leaf spring 503 absorbs part of the vibration, and transmits the vibration to the second spring 506 and the third spring 510 through the fifth connecting block 504. To absorb vibration, the fourth block 511 contacts the side of the power meter body 1 to achieve front and rear limit, and the first circular column 505 and the second circular column 509 contact the side of the sixth connecting block 507 at this time, and the remaining vibration is transmitted to the leaf spring for absorption, and the shapes of the second spring 506 and the third spring 510 are maintained by the first circular column 505 and the second circular column 509, so that they do not interfere with the contact of the third block 508 with the side slot of the power meter body 1, and stable front and rear fixation is achieved through the fourth block 511, the second block 401 and the power meter dial 2.
