The pin 31 is slidably arranged on the guide rod 32 and has an extended position for inserting into the locking hole 111 and a withdrawn position for withdrawing from the locking hole 111. The elastic member 33 is compressed and arranged between the second clamping plate 2 and the pin 31. The elastic member 33 is also sleeved outside the guide rod 32. The elastic member 33 provides an elastic force, which constantly makes the pin 31 have a tendency to move from the withdrawn position to the extended position.

[0026] Please refer to Figures 3 to 6 The second clamping plate 2 has a connecting hole 21 corresponding to the plug pin 31 for the plug pin 31 to extend to the locking hole 111. The connecting hole 21 is arranged along the length direction of the second clamping plate 2. The guide rod 32 and the elastic member 33 are installed in the connecting hole 21. The plug pin 31 is slidably arranged in the connecting hole 21. When the second clamping plate 2 is in the clamping position, the connecting hole 21 is opposite to the locking hole 111, thereby facilitating the insertion or withdrawal of the plug pin 31.

[0027] Please refer to Figures 3 to 6 The second clamping plate 2 is provided with a card hole 22 corresponding to the plug pin 31, the card hole 22 is connected with the connecting hole 21, and the plug pin 31 extends toward the card hole 22 to form a card engaging portion 311.

When the second clamping plate 2 is in the clamping position, the pin 31 can extend into the locking hole 111 to lock the relative rotation between the first clamping plate 1 and the second clamping plate 2, thereby achieving locking. When disassembly is required, when the engaging portion 311 and the engaging hole 22 are engaged, the pin 31 overcomes the elastic force of the elastic member 33 and is locked in the withdrawn position. The pin 31 withdraws from the locking hole 111 so that the first clamping plate 1 can rotate freely relative to the second clamping plate 2 to open the clamped zipper.

[0033] By combining the first clamping plate 1, the second clamping plate 2 and the elastic pin assembly 3 together, the first clamping plate 1 extends toward the second clamping plate 2 to form a connecting portion 11, and the second clamping plate 2 is pivotally connected to the connecting portion 11, so that the second clamping plate 2 rotates relative to the first clamping plate 1 and has a clamping position and an opening position. The extension of the connecting portion 11 can provide space for the relative pivoting between the first clamping plate 1 and the second clamping plate 2. A locking hole 111 is provided on the connecting portion 11. The elastic pin assembly 3 is provided on the second clamping plate 2. The elastic pin assembly 3 has a movable pin 31 for locking. When the second clamping plate 2 is in the clamping position, the pin 31 The relative rotation between the first clamping plate 1 and the second clamping plate 2 can be locked by extending into the locking hole 111, so that the first clamping plate 1 and the second clamping plate 2 are maintained in a clamped state to clamp the zipper, thereby realizing the connection between the quick-release zipper head 100 provided by the utility model and the zipper. The insertion pin 31 can exit the locking hole 111 to allow the first clamping plate 1 to rotate relative to the second clamping plate 2, thereby realizing the disassembly between the quick-release zipper head 100 provided by the utility model and the zipper, that is, realizing the quick-release function, and providing a quick-release zipper head structure for use in emergency situations, which has the advantages of easy assembly and simple structure.
