[0005] In some embodiments, a guide seat is fixedly disposed in the guide rod via a limiting member, the guide seat is provided with a limiting groove corresponding to the positioning hole, and the guide seat is provided with a guiding portion close to the inner wall of the guide rod.

[0006] In some embodiments, when the guide rod is inserted into the mounting hole, the elastic protrusion slides along the guide portion and falls into the limiting groove under the action of its own elasticity, so that the guide rod cannot fall outward.

[0007] In some embodiments, the connection seat is provided with a disassembly hole corresponding to the snap-in hole.

[0008] In some embodiments, a radially inward force is applied to the elastic protrusion through the disassembly hole so that the elastic protrusion is disengaged from the limiting groove, and the guide rod can be removed.

[0009] In some embodiments, the elastic protrusion includes a fixing seat, an extension rod and a positioning portion, the extension rod connects the positioning portion and the fixing seat, the fixing seat is fixed to the bottom of the mounting hole through a limiting member, and the positioning portion is clamped with the limiting groove.

[0010] In some embodiments, a positioning groove is provided at the bottom of the mounting hole, and the positioning groove matches the shape of the fixing seat so that the elastic protrusion will not deflect.

[0011] In some embodiments, a step is provided at the bottom of the mounting hole for supporting the guide rod so that the limiting groove, the positioning hole and the disassembly hole are aligned.

[0012] The beneficial effect of the present application is that installation and fixation can be completed by inserting the guide rod into the installation hole of the connecting seat, the structure is simple and the installation is relatively reliable, and when disassembling, it only needs to press the elastic protrusion inward to disengage it from the limit groove to complete the disassembly.
