[0002] A patent application (application number 201310216774.3) discloses a power-assisted handle for a refrigerator drawer door, used for refrigerating items inside a vehicle. It solves problems such as excessive magnetic force between the refrigerator body and door, difficulty in opening, inconvenience, complex and ineffective power-saving structures, and easily damaged components in existing refrigerators. This power-assisted handle for the refrigerator drawer door is installed on the top edge of the drawer door and includes a decorative strip with a long, narrow groove. A long, narrow handle is hinged to the groove. Power-assisted push rods are symmetrically hinged to both ends of the decorative strip. The two ends of the handle and the power-assisted push rods form a steering drive adjustment connection. A tension spring connects the hinge point at the end of the handle to the drive adjustment point of the power-assisted push rod. This handle is mainly used to assist in opening the refrigerator door, but it does not have a locking function or the ability to pull the door; its overall function is relatively simple. Furthermore, the existing locking mechanism is not suitable for outdoor use. When used outdoors, the drawer is easily disengaged from the latch or even falls out of the refrigerator due to vibration or other external forces. Also, when using the refrigerator outdoors, the drawer is easily pulled out by lifting it directly with the handle. Utility Model Content

Connecting pieces 11 are fixed to both ends of the drive shaft 10. Both the connecting pieces 11 and the handle 1 are fixed to the drive shaft 10. When the handle 1 is pulled, it drives the drive shaft 10 and the connecting pieces 11 to rotate synchronously. A torsion spring 17 is mounted on the connecting piece 11. Drive rods 12 are hinged to both sides of the connecting piece 11. The latch 2 is positioned between the drive rods 12 and hinged to the other end of the drive rods 12. The latch 2 is hinged to the side wall of the door 4 via a first connecting rod 13. Therefore, the connecting piece 11 rotates during operation. When in motion, the latch body 2 is pulled by the torsion spring 17, the drive rod 12, and the first connecting rod 13. The angle of the drive rod 12 and the first connecting rod 13 allows the latch body 2 to move vertically up and down. In this embodiment, the latch body 2 is provided with a movable groove 14 and a limiting groove 15. A second connecting rod 16 is also fixed on the side wall of the door body 4. The two ends of the second connecting rod 16 are respectively placed in the movable groove 14 and the limiting groove 15. A return spring 18 is provided at the bottom of the latch body 2. The second connecting rod 16 and the limiting groove 15 cooperate to make the latch body 2 only move up and down along a certain height. The return spring 18 can drive the latch body 2 to return to its original position.
