[0005] The worm gear locking mechanism of the utility model is arranged on the top of the machine base, and the insertion hole is arranged on the shell bottom plate of the machine head.

[0006] Preferably, the driving device is a hand wheel, which is arranged outside the housing for easy operation.

[0007] A pressing plate matched with the pressing block is arranged on one side of the insertion hole, and the pressing block is pressed on the pressing plate after rotating.

[0008] Among them, the matching surfaces on the pressing block and / or the pressing plate are inclined surfaces, so that the pressing block can gradually press the pressing plate during the rotation process, making the locking tighter and more effectively preventing the machine head from moving.

[0009] Preferably, the connecting shaft, the worm gear and the pressure block are all key-connected.

[0010] The beneficial effects of the utility model are:

[0011] 1. Improve the stability of machine operation: By introducing the worm gear locking mechanism and utilizing the self-locking performance of the worm gear, the machine head can be firmly locked on the machine base during high-speed operation of the dough mixer, effectively preventing the movement or jumping of the machine head, thereby greatly improving the stability of machine operation and the safety of food processing.

[0012] 2. Enhanced locking effect: The mating surface between the pressure block and the pressure plate is designed to be an inclined surface, so that the pressure block can gradually press the pressure plate during the rotation process, forming a tighter locking effect. This design not only enhances the reliability of locking, but also maintains a stable locking state during long-term use.

[0013] 3. Improve operational convenience: The hand wheel is used as the driving device and is set outside the shell, so that the user can easily operate the locking mechanism without opening the inside of the machine. This design not only simplifies the operation process, but also improves the safety of operation and avoids safety risks caused by improper operation.

[0014] 4. Enhance the versatility and flexibility of the equipment: Since the head part can be flexibly disassembled and replaced with different stirring rods (such as dough mixing rods or egg beating rods), the utility model not only ensures stability, but also enhances the versatility and flexibility of the equipment, and can meet the diversified operations under different food processing needs.

[0015] 5. Extend the service life of equipment: By effectively preventing the movement and jumping of the machine head during operation, the wear and vibration inside the machine are reduced, thereby extending the service life of the equipment and reducing maintenance costs.

[0016] The worm gear locking mechanism for preventing movement of the head of a vertical food mixer of the utility model has remarkable beneficial effects in improving the stability of machine operation, enhancing the locking effect, improving the convenience of operation, enhancing the versatility and flexibility of the equipment and extending the service life of the equipment.
