The rear side of the installation shell 71 is fixed to the front end of the support plate 4 by bolts, which is convenient for installation, disassembly and maintenance of the installation shell 71. The inner wall of the installation shell 71 is slidably connected with a clamping plate 72, and an anti-slip strip is provided on the inner side of the clamping plate 72 to increase the fixing effect of the grounding wire. A sliding groove is provided at the front end of the sleeve 6, and the rear side of the clamping plate 72 slides on the inner wall of the sliding groove, and the grounding wire is fixed to the inner wall of the sleeve 6 through the clamping plate 72.

[0034] Reference Figure 3 - Figure 5 The front end of the clamping plate 72 is fixedly connected to a movable plate 73, which is used in conjunction with the limiting plate 76 to drive multiple groups of movable plates 73 to move at the same time, thereby releasing the limiting of multiple groups of grounding wires at the same time, improving the efficiency of installation and disassembly, and at the same time facilitating maintenance for workers. The outer wall of the bottom end of the movable plate 73 is slidably connected to the inner wall of the mounting shell 71, and the inner wall of the front end of the mounting shell 71 is rotatably connected to a pull rod 74, and a button cap 78 is provided at the front end of the pull rod 74. The button cap 78 facilitates workers to pull the pull rod 74 to release the limiting of the grounding wire, and the pull rod 74 rotates on the inner wall of the movable plate 73 near the outer wall of the front end of the clamping plate 72. The movable plate 73 is elastically connected to the mounting shell 71 by a reset spring 75. The grounding wire is clamped on the sleeve 6 by the elastic force of the reset spring 75 to establish an electrical connection, effectively reducing installation time and cost, and providing a stable electrical connection.

[0035] Reference Figure 4 - Figure 5The front end of the return spring 75 is fixedly connected to the inner wall of the mounting shell 71, and the rear end of the return spring 75 is fixedly connected to the front wall of the movable plate 73. The mounting shell 71 is slidably connected to the limit plate 76 on the inner wall of the top of the movable plate 73, which is used to drive multiple groups of movable plates 73 to move at the same time, thereby improving the convenience and efficiency of operation. The inner wall of the top of the limit plate 76 is threadedly connected with a threaded rod 77, and the outer walls of the front and rear ends of the threaded rod 77 are rotatably connected to the inner wall of the mounting shell 71. The threaded rod 77 is rotated to drive the limit plate 76 to move on the inner wall of the mounting shell 71, thereby driving multiple groups of movable plates 73 to move, thereby improving the efficiency of operation and facilitating maintenance for workers. The front end of the threaded rod 77 is fixedly connected to the button cap 78, and the button cap 78 is provided with multiple groups, which is convenient for workers to rotate the threaded rod 77. The mounting shell 71 and the clamping plate 72 are set to insulating material to ensure the safety of the grounding wire device when used in an electrical environment.

[0036] Reference Figure 1 , Figure 2 and Figure 6 The inner wall of the support seat 3 is provided with an adjustment component, which includes a threaded rod 81, which is used to drive the support plate 4 to slide on the inner wall of the support seat 3, and adjust the position of the support plate 4, so that workers can install the grounding wire conveniently and improve the installation efficiency. The outer walls of the front and rear ends of the threaded rod 81 are rotatably connected to the inner wall of the support seat 3, so that the threaded rod 81 is more stable during work. The outer wall of the threaded rod 81 is threadedly connected to the inner wall of the support plate 4. The support seat 3 is fixedly connected with a stabilizing rod 82 on the upper and lower sides near the threaded rod 81. The stabilizing rod 82 is provided with multiple groups for stably moving the support plate 4. The outer wall of the stabilizing rod 82 is slidably connected to the inner wall of the support plate 4. The inner wall of the front end of the threaded rod 81 is slidably connected with a rotating rod 83. The rotating rod 83 is pulled to make the rotating rod 83 slide out from the inner wall of the threaded rod 81, which is convenient for workers to rotate the threaded rod 81 without hindering the closing of the box cover 2.

[0037] Working principle: During use, when the grounding wire needs to be installed, first pull the rotating rod 83 to the front end to drive the rotating rod 83 to slide on the inner wall of the threaded rod 81. At this time, rotate the rotating rod 83 to make the rotating rod 83 drive the threaded rod 81 to rotate on the inner wall of the support seat 3. The threaded rod 81 drives the support plate 4 to slide on the outer wall of the stabilizing rod 82 on the support seat 3 through the thread, thereby moving the support plate 4 to the front side of the box body 1, making it convenient for workers to connect wires.

[0038] First, pull the pull rod 74 to drive the movable plate 73 and the clamping plate 72 to slide on the inner wall of the mounting shell 71, so that the mounting shell 71 slides out of the sliding groove on the sleeve 6, and at the same time squeezes the reset spring 75. At this time, the grounding wire is inserted from the bottom end of the sleeve 6, and then the pull rod 74 is released. The elastic force of the reset spring 75 drives the movable plate 73 and the clamping plate 72 to slide on the inner wall of the mounting shell 71, so that the mounting shell 71 fixes the grounding wire in the sleeve 6.

[0039] When multiple groups of wires need to be installed at the same time, the button cap 78 is rotated to drive the threaded rod 77 to rotate on the inner wall of the installation shell 71. The threaded rod 77 drives the limit plate 76 to move forward through the thread, thereby squeezing the upper side of the multiple groups of movable plates 73, so that the multiple groups of movable plates 73 move synchronously, and squeeze the multiple groups of reset springs 75. After the grounding wire is placed in the sleeve 6, the button cap 78 can be rotated in the direction to fix the multiple groups of grounding wires at the same time, thereby improving the convenience of operation and installation efficiency. The same limit plate 76 can release the fixation of multiple groups of grounding wires at the same time.

[0040] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
