ABSTRACT:
The rake includes a flat rake body with a flared portion provided with a plurality of prongs and a head portion opposite to the flared portion. The flat rake body has a first slot formed adjacent to a free end thereof and a second slot which has a second length that is shorter than a first length of the first slot and which is spaced from the first slot in a parallel manner. The rake further includes a resilient fastening unit that has a first inverted U-shaped member with two legs, a second inverted U-shaped member that is smaller than the first U-shaped member and that has two legs, and a connecting rod which interconnects one of the legs of the first and second U-shaped members. Each of a remaining one of the legs of the first and second U-shaped members has an extension that extends toward one another and that defines cooperatively a clearance therebetween. The two legs of the first and second U-shaped members respectively define first and second distances which are correspondingly equal to the first and second lengths of the first and second slots.
