A device and a method of use thereof, for expanding elastic sleeves for easy mounting over and removal from mechanical joints, the device comprising a mandrel including a base section having a perimeter and a plurality of spokes; each spoke having a base end and a far end; the base end of each spoke being pivotally joined to the perimeter of the base section, such that the mandrel can alternate between a closed state and an open state; such that in the closed state, the plurality of spokes pivotally converge at their far ends to form a cone shape and each spoke forms a first angle with the base section, and in the open state, the plurality of spokes pivot in the opposite direction to assume a second angle with the base section that is substantially larger than the first angle. |
