[0048] Embodiment 3

[0049] Reference Figures 1-6 The third embodiment of the present application is different from the first two embodiments in that the inner diameter of the installation slot 201a is greater than the diameter of the wiring rod 101.

[0050] The inner diameter of the installation slot 201a is greater than the diameter of the wiring rod 101, which can reduce the frictional resistance during installation, make the wiring rod easier to insert and remove from the installation slot, improve the convenience of installation and removal, and also reduce the contact area between the wiring rod and the installation slot, thereby reducing wear and extending the service life of the product. At the same time, the material will expand and contract due to temperature changes, and a larger inner diameter can provide a certain space for the wiring rod to adapt to the size changes caused by temperature changes, avoid damage or dysfunction caused by expansion, and also reduce electrical problems caused by poor contact, such as short circuit or leakage, thereby improving the safety of electrical connection.

[0051] Further, the outer side of the installation shaft 201 is provided with a clamping groove 201c, and the side of the clamping groove 201c close to the connecting shaft 202 is provided with a slope 201c-1, and the clamping groove 201c is in communication with the installation slot 201a.

[0052] The clamping groove 201c is used to fix the first elastic piece 300 and ensure its stability during connection and disconnection; the design of the clamping groove allows the elastic sheet to be reliably fixed in place, reducing connection problems caused by poor contact or accidental movement. The clamping groove 201c allows the first elastic piece 300 to move within it, so that the wiring rod 101 can abut against the elastic sheet 300, thereby achieving good electrical connection. The slope 201c-1 provides a smooth transition, reducing the resistance during installation.

[0053] Further, one side of the first elastic member 300 is fixedly connected with the inner wall of the clamping groove 201c, and the other side of the first elastic member 300 is movably connected with the clamping groove 201c, and the movable end of the first elastic member 300 abuts against the wiring rod 101.

[0054] The first elastic member 300 includes a first inclined surface fixedly connected with the inner wall of the clamping groove 201c, the first inclined surface is arranged obliquely downward, the other end of the first inclined surface is provided with a second inclined surface arranged obliquely upward, the other side of the second inclined surface is provided with a third inclined surface arranged obliquely downward, and the other side of the third inclined surface is provided with a fourth inclined surface arranged horizontally. The connection position of the first inclined surface and the second inclined surface is in contact with the surface of the wiring rod 101 inserted into the installation groove 201a, so as to provide a downward force to the wiring rod 101, and the wiring rod 101 is fixed. The connection position of the second inclined surface and the third inclined surface is not in contact with the surface of the wiring rod 101, and the user provides pressing or pushing to drive the first elastic member 300 to fix or unlock the wiring rod 101. The connection position of the third inclined surface and the fourth inclined surface is in contact with the surface of the wiring rod 101 together with the fourth inclined surface, and the wiring rod 101 is fixed.

[0055] In the present application, the fixing of the wiring rod 101 and the installation groove 201a can also be fixed by a fixing ring, and the fixing ring is arranged at the guide groove 201b and fixed by extrusion to fix the wiring rod 101 and the installation groove 201a.

[0056] Operation process: after the wiring rod 101 is inserted into the installation groove 201a, the first elastic member 300 is pressed to clamp the movable end of the first elastic member 300 into the gap between the clamping groove 201c and the wiring rod 101, so as to fix the wiring rod 101 in the installation groove 201a. When it is needed to release the fixing of the wiring rod 101, the first elastic member 300 is pushed to move the movable end of the first elastic member 300 out of the gap between the clamping groove 201c and the wiring rod 101.

[0057] In summary, by arranging the wiring shaft 102 and the connecting shaft 202 for clamping the wire, and arranging the end of the wiring rod 101 to be connected with the inside of the installation shaft 201, the quick installation and disassembly are realized, and the convenience of use is improved.
