[0029] When in use, first fix the installation shell 2 to the specified position, then push the power display meter body 1 into the installation shell 2, and after the power display meter body 1 moves backward to a suitable position, the card block 3 is inserted into the installation shell 2, thereby realizing convenient installation of the power display meter body 1. When the power display meter body 1 needs to be removed, the power display meter body 1 is pulled out, and the card block 3 is separated from the installation shell 2, thereby realizing portable disassembly. Example 2

[0030] Based on Example 1, please refer to Figure 3 The left and right sides of the mounting shell 2 are fixedly connected with mounting plates 5 by welding. Two clamping rods 6 symmetrically distributed up and down are slidably arranged on the mounting plate 5. The clamping rod 6 is used to clamp the power display meter body 1. The clamping rod 6 is provided with an inclined surface. When the power display meter body 1 is installed in the mounting shell 2, the power display meter body 1 can squeeze the clamping rod 6 to move outward under the action of the inclined surface on the clamping rod 6. The clamping rod 6 is sleeved with a first elastic member 7 for resetting the clamping rod 6. The two ends of the first elastic member 7 are respectively connected to the clamping rod 6 and the mounting plate 5.

[0031] When the power display meter body 1 is pushed into the mounting housing 2, the power display meter body 1 contacts the clamping rod 6. Under the action of the inclined surface, the power display meter body 1 squeezes the clamping rod 6 to move outward, and the first elastic member 7 is compressed accordingly. After the power display meter body 1 is locked, under the restoring elastic force of the first elastic member 7, the clamping rod 6 is reset inward to clamp and fix the power display meter body 1, thereby achieving reinforcement and improving the stability of installation.

[0032] See also Figure 4 and Figure 5 A protective plate 8 is fixed to the bottom of the mounting shell 2 by welding, and the bottom of the power display meter body 1 is fixed with the same protective plate 8 by a reinforcing block 13. The left and right parts of the two protective plates 8 are embedded with magnetic members 9, and the magnetic members 9 are used to fix the two protective plates 8. A guide rod 11 is fixed to the middle part of the protective plate 8 by welding. A clamping plate 10 for clamping the wire 4 is slidably penetrated on the guide rod 11, and the clamping plate 10 is made of rubber so that the wire 4 can be protected when clamping the wire 4. The guide rod 11 is provided with a second elastic member 12 for resetting the clamping plate 10, and the two ends of the second elastic member 12 are respectively connected to the clamping plate 10 and the corresponding protective plate 8.

[0033] After the power display meter body 1 is installed in the mounting housing 2, the protective plate 8 on the power display meter body 1 contacts the protective plate 8 on the mounting housing 2 and is fixed by the magnetic member 9, and the two clamping plates 10 clamp the wire 4 to fix it, thus playing an anti-drop and protective role.

[0034] See also Figure 6 The left and right sides of the power display meter body 1 are fixedly connected with guide rails 14 by welding. The two guide rails 14 are slidably provided with a protective cover 17. The protective cover 17 is located on the front side of the power display meter body 1. The protective cover 17 is used to protect the power display meter body 1. A placement rack 18 is fixedly connected to the top of the protective cover 17 by welding. The placement rack 18 can be used to place cleaning items. A wiping strip 19 is placed in the placement rack 18. The wiping strip 19 can be taken out to wipe the protective cover 17. A guide rod 15 is fixedly connected to the lower part of the guide rail 14 by welding. The protective cover 17 slides longitudinally on the guide rod 15. The guide rod 15 is used to guide the protective cover 17. A third elastic member 16 for resetting the protective cover 17 is sleeved on the guide rod 15. The two ends of the third elastic member 16 are respectively connected to the protective cover 17 and the guide rail 14.
