DETAILED DESCRIPTION

[0017] The present application is further described in detail below in conjunction with the accompanying drawings. It is necessary to point out here that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technical personnel in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0018] Example

[0019] like Figure 1 , Figure 2 , Figure 3 As shown, a housing back plate comprises a back plate body 1, a plurality of mounting holes 2 are provided at the edge of the back plate body 1, a handle 3 is rotatably connected to the outer side of the back plate body 1, a protective cover 4 is provided on the handle 3, a plurality of fixing holes 5 penetrating the handle 3 are provided on the protective cover 4, two oppositely arranged fixed bases 8 are fixedly provided on the back plate body 1, an adjustment rod 6 rotatably connected to the fixed base 8 is integrally provided at both ends of the handle 3, an adjustment hole 7 is provided on the adjustment rod 6, both ends of the handle 3 are rotatably connected to the two fixed bases 8, a sector-shaped positioning plate 14 is provided on the two fixed bases 8, a plurality of plug holes 16 are provided on the sector-shaped positioning plate 14, adjustment holes 7 cooperating with the plug holes 16 are provided at both ends of the handle 3, and a positioning assembly passing through the plug holes 16 and the adjustment holes 7 is provided on one side of the sector-shaped positioning plate 14. When in use, the adjustment hole 7 is concentrically matched with one of the plug holes 16, and then the plug hole 16 is fixed to the adjustment hole 7 by the positioning assembly to achieve angle adjustment.

[0020] like Figure 1 , Figure 2 As shown, the positioning assembly includes a fixed base plate 10 fixedly arranged on one side of a fan-shaped positioning plate 14, a pull rod 12 slidingly penetrates the upper side of the fixed base plate 10, one end of the pull rod 12 is fixedly connected to a pull plate 9 cooperating with the fan-shaped positioning plate 14, one side of the pull plate 9 is fixedly provided with a plurality of positioning rods 15 respectively slidably plugged with the sockets 16, a pull pin 11 is fixedly arranged on the other end of the pull rod 12, and one side of the pull plate 9 is provided with a clamping spring 13 fixedly connected to the fixed base plate 10, through the clamping spring 13, the pull plate 9 can be tightly fitted to one side of the fan-shaped positioning plate 14, so that the positioning rod 15 on one side of the fan-shaped positioning plate 14 is tightly inserted into the adjustment hole 7, to prevent the positioning rod 15 from detaching and affecting the stability.
