As shown in fig. 18 to 20, the main body 20 of the present embodiment is in a -shaped structure, the middle area of the -shaped structure is an accommodating area, the hooking component can enter the accommodating area from an opening at one side, the hooking judging mechanism 10 is still disposed at the top of the -shaped structure, the trigger 12 is disposed in the accommodating area, the connecting rod 35 is disposed at the bottom of the -shaped structure in a penetrating manner, the push block 34 is disposed at the bottom of the accommodating area, and the connecting rod 35 is in threaded engagement with the main body 20 in the present embodiment, so that the connecting rod 35 can axially move when rotating, thereby driving the push block 34 to axially move upwards or downwards, and approaching or separating from the trigger 12. When the hanging component stretches into the accommodating area, the connecting rod 35 rotates, the push block 34 moves upwards and contacts and abuts against the hanging component to move upwards together, the hanging component moves upwards and contacts the trigger piece 12 to push the trigger piece 12 to move upwards, so that the trigger piece 12 triggers the first detection piece 13 and the second detection piece 14, the first detection piece 13 detects whether the hanging component is connected or not, and the second detection piece 14 forms a conducting loop with the control board through the trigger piece 12, the metal hanging component, the push block 34, the connecting rod 35, the main body part 20 and other components, and detection of the material of the hanging component is achieved.

Since the distance between the push block 34 and the trigger piece 12 is larger when the hooking component is not hooked in the present embodiment, the second detecting piece 14 may be directly connected to the trigger piece 12 or the reset piece 15 in addition to the manner of contact fit with the trigger piece 12 only when the trigger piece 12 is located at the triggering position, that is, the second detecting piece 14 is always electrically connected to the trigger piece 12, when the hooking component is not hooked, the loop will not be conducted due to the distance between the push block 34 and the trigger piece 12 and between the trigger piece 12 and the main body 20, and when the hooking component is hooked, the loop will be conducted when the hooking component is simultaneously contacted with the trigger piece 12 and the push block 34.

The connecting rod 35 of this embodiment is further connected to the operating member 40, and the connecting rod 35 and the operating member 40 rotate synchronously, and because the connecting rod 35 is in threaded engagement with the main body 20, when an operator holds the operating member 40, after the operator enters the accommodating area, the operator can manually rotate the operating member 40, and the operating member 40 drives the connecting rod 35 to rotate together, so that the push block 34 is close to the trigger member 12, and the hooking operation is realized.

It should be noted that, in the above embodiments, a plurality refers to at least two.
