Patent ID: 8790107

Claim:
An ice cream scoop, comprising: a handle, having a first end and a second end separated from each other and disposed on a longitudinal axis, and a chamber contained in the first end of the handle; a scooper, having a hemispherical internal wall, and coupled to the first end of the handle; a scraper, swingingly installed in the scooper, and having a first end and a second end separated from each other and disposed on the longitudinal axis, and a first end of the scraper being pivotally coupled to the scooper, and a link rod being extended from the second end of the scraper, passed through the scooper, and extended into the chamber of the first end of the handle; a gear being installed on the link rod and rotated synchronously with the link rod, and having a plurality of transmission gear teeth arranged in a radial shape and disposed on the gear; an operating device, having a first distal portion and a second distal portion separated from each other and disposed on the longitudinal axis, and the first distal portion of the operating device being pivotally coupled to the first end of the handle by a pin, such that the operating device can be swayed between a popup position and a press position with respect to the handle, and the operating device further including a plurality of grooves using the pin as an axis and arranged in a radial shape, and having an equal distance from the pin, and the plural transmission gear teeth being engaged corresponding to the plural grooves, and push the operating device to the popup position; and a spiral spring, accommodated in the chamber of the first end of the handle and sheathed on the link rod, and one side of the spiral spring abutting the scooper at the first end of the handle, and the other side abutting one side of the gear, and one end of the spiral spring abutting the scooper having an end tip fixed on the first end of the handle, and another end tip at the other end of the spiral spring abutting the gear being fixed onto the gear, when the gear rotates and drives the spiral spring to rotate to provide a position restoring effect; the operating device is normally moved to the popup position by the resilience of the spiral spring, when the operating device sways from the popup position to the press position, the plural grooves engage the corresponding plural transmission gear teeth from down to up in order and drive the gear, the gear rotates the link rod to drive scraper sway along the internal wall of the scooper.
