During this period, the spring 107 will be stretched and reset. Until the cabinet door body 2 is opened and closed at a suitable angle, the elastic force of the spring 107 causes the square pin 104 to drive the clamping block 105 to engage with the wide gear 101, locking the angle of the cabinet door body 2 at this time. It can achieve the purpose that the upward-lifted cabinet door can stop at any angle, and there is no need to hold the cabinet door to take items in the freezer, providing convenience for the user to take items in the freezer.
