[0043] When the cam 314 is in the unlock state, the first locking block 304 is unlocked, and the second locking block 304 is unlocked, and the cam 314 is unlocked. The right side of the block 303 contacts the left side of the first clamping block 304 to fix the box body 301 and the symmetrically arranged box body 301. The fixing component 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.

[0044] 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 the fourth connecting block 502, the top of the fourth connecting block 502 is fixedly connected to the second leaf spring 503, the top of the second leaf spring 503 is fixedly connected to the fifth connecting block 504, the top of the fifth connecting block 504 is fixedly connected to the first circular column 505, the second circular column 509, the second spring 506 and the third spring 510, the bottom plate of the second spring 506 and the third spring 510 is fixedly connected to the sixth connecting block 507, the top of the sixth connecting block 507 is fixedly connected to the third clamping block 508, the inner wall of the box body 301 is fixedly connected to the 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;

[0045] The length of the components of the horizontal stabilization mechanism 5, except for the fourth clamping block 511, is the same as the length of the side clamping slot of the power meter main body 1. The side of the fourth clamping block 511 is in contact with the surface of the power meter main body 1. By setting the horizontal stabilization mechanism 5, it cooperates 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 the carrying process are absorbed through the second spring 506, the third spring 510, the first leaf spring 501 and the second leaf spring 503, thereby achieving a high level of protection for the power meter, allowing the power meter to withstand interference from various vibrations during the carrying process, and providing users with a reliable measurement tool.

[0046] The working principle of this embodiment is as follows: the process of the first embodiment is supplemented to achieve horizontal stability. 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 transmits 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 transmits 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. The first circular column 505 and the second circular column 509 are in contact with the side of the sixth connecting block 507 at this time, and the remaining vibration is transmitted to the leaf spring for absorption. 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 fixation in the front and rear is achieved through the fourth block 511, the second block 401 and the power meter dial 2.
