The driving component is arranged on one side of the clamping ring without affecting the normal clamping of the wine spear. At the same time, a baffle is arranged on the top of the clamping ring. When the driving component is driven through verification, the baffle can be prompted to open or close. At the same time, the movable claw arranged on the spear tube is linked to the driving component. When the driving component drives the baffle to close, the movable claw opens; when the driving component drives the baffle to open, the movable claw closes. The arrangement of the baffle and the movable claw can greatly enhance the safety of the wine spear. The wine spear can only be opened after verification, which avoids the theft of wine in the barrel and the tampering or adulteration of beer during the distribution process.

[0007] The above-mentioned wine spear can be further configured as follows: the driving component includes an installation box installed on one side of the clamping ring, a driving motor is installed in the installation box, the driving motor is provided with a central axis connected to the baffle, the installation box is located below the driving motor and is provided with a partition, the partition is provided with a power supply, a driving circuit and a verification chip, and the power supply, driving circuit, verification chip and driving motor are electrically connected.

[0008] By adopting the above technical solution, a driving motor is installed in an installation box set on one side of the clamping ring, and the central axis of the driving motor is connected to the baffle above the clamping ring for linkage. At the same time, a power supply, a driving circuit and a verification chip are set in the compartment below the driving motor. Only by passing the verification of the verification chip, the power supply controls the driving motor through the driving circuit to drive the baffle and the movable claw for linkage.

[0010] With the above technical solution, the NFC chip is used as the core of the circuit, connected to the power supply and stabilized by the voltage stabilizing diode D1 in series, ensuring the stability and reliability of the entire circuit. The resistor R1 is used as a current limiting element to protect the subsequent circuit from the impact of excessive current. The transistor Q1 is used as a switching element, and the resistor R4 and the capacitor C2 are connected in parallel between its base and emitter to form a low-pass filter, which optimizes the response speed and stability of the circuit. The control chip U1 is connected in series with the drive motor, and the current limiting protection is performed by the resistor R5 in series, ensuring the safe operation of the drive motor. At the same time, a verification chip circuit that provides a signal is also connected in parallel between the control chip U1 and the NFC chip, so that the circuit can only allow the drive motor to work by giving the verification chip circuit signal through the adapted NFC authentication. The rectifier diodes D3 and D4 are used for rectification and protection respectively, ensuring that the current direction in the circuit is correct and stable. In addition, the resistors R2 and R3 are used as voltage dividers to provide a stable working voltage for the circuit.

The adapted NFC can enable the drive motor to work only after being verified by the verification chip. The capacitors C3 and C4 connected in series are used as input filters to effectively suppress high-frequency noise and interference signals, thereby ensuring the data transmission quality between the NFC chip and the verification chip. At the same time, the capacitors C7 and C8 connected in parallel are used as bypass capacitors to further stabilize the power supply voltage and reduce the impact of power supply fluctuations on circuit performance.

[0014] By adopting the above technical solution, the first claw arm, the second claw arm and the claw are hingedly arranged so that there is a certain movable space and range between the claw arms. At the same time, the first contraction spring and the second contraction spring can retract the first claw arm and the second claw arm when the baffle is opened, without affecting the normal extraction and use of the wine spear. The second claw arm is linked to the drive motor, and the second claw arm can be lifted when the drive motor is working.

[0015] The above-mentioned wine spear can be further configured as follows: a connecting hole is provided on the second claw arm, the central axis is located above the driving motor and is sleeved with an upper ring and a lower ring, a connecting groove is formed between the upper ring and the lower ring, the connecting hole and the connecting groove are connected by a connecting line, and when the central axis rotates, it can drive the connecting line to drive the first claw arm and the second claw arm to open.

[0016] By adopting the above technical solution, a connecting hole is provided on the second claw arm, and an upper ring and a lower ring on the central axis of the driving motor form a connecting groove. The connecting hole and the connecting groove on the second claw arm are connected with a connecting wire, and the connecting wire is connected to the connecting groove through the cavity part in the valve body.

At the same time, the movable claw arranged on the spear tube is linked with the driving component. When the driving component drives the baffle to close, the movable claw opens; when the driving component drives the baffle to open, the movable claw closes. The arrangement of the baffle and the movable claw can greatly enhance the safety of the wine spear. BRIEF DESCRIPTION OF THE DRAWINGS
