When disassembly is required, the locking member can be disengaged from the locking groove through the control component.

[0007] It is further configured as follows: the control component package is provided with a control groove connected to the locking groove on one side of the sensing device housing, a guide slope is formed on the side of the locking member facing the inner wall of the control groove, and a trigger member is provided between the locking member and the guide slope, and when the trigger member moves toward the control groove, the trigger member and the guide slope cause the locking member to move toward the sliding channel.

[0008] By adopting the above technical solution, the trigger member is pressed to move toward the control groove, and the trigger member and the guide inclined surface form a linkage to move toward the locking member, so that the locking member enters the sliding channel. At this time, the locking member disengages from the locking groove, and the plug connector can be disengaged from the docking groove for quick disassembly, and the operation is simple.

[0009] It is further configured as follows: a positioning groove is opened in the control groove in the direction where the trigger member faces the control groove, a rebound spring is arranged in the positioning groove, and the rebound spring drives the trigger member to separate from the guide inclined surface.

[0010] By adopting the above technical solution and setting the rebound spring, the trigger member can be separated from the guide inclined surface, so that the trigger member can be in a reset state when it needs to be disassembled next time, which is convenient for recycling during disassembly.

[0011] It is further configured as follows: a limiting portion is formed on the trigger member, a limiting member is arranged in the control groove, a limiting protrusion is formed on the limiting member to limit the limiting portion from leaving the control groove, and a fixing structure is provided between the limiting member and the control groove.

[0012] By adopting the above technical solution, the limiting protrusion can limit the trigger member from leaving the control groove, so that the next time the trigger member is used, there is no need to go through the tedious steps of installing the trigger member into the control groove, which facilitates the direct use of the trigger member when it is pressed next time.

[0013] It is further configured as follows: the fixing structure includes a fixing groove opened in the control groove, a first locking tooth is formed in the fixing groove, and a second locking tooth is formed at the limiting member, and the first locking tooth and the second locking tooth form a locking relationship.

[0014] By adopting the above technical solution, the limiting member is inserted into the fixing groove, and the first locking tooth and the second locking tooth are locked with each other, so that the limiting member is fixed in the fixing groove.

[0015] It is further configured that: an alignment bevel groove is formed at the notch of the docking groove, and the alignment bevel groove allows the locking member to slide into the docking groove. When the plug connector is plugged into the docking groove, the locking member corresponds to the locking groove.

[0016] By adopting the above technical solution, during the process of inserting the plug connector into the docking groove, the locking member can quickly find the locking groove for locking through the setting of the alignment bevel groove, and the structure is simple and practical.
