The first inclined surface 8 and the second inclined surface 9 are used in conjunction with each other. The fixed sleeve 6 is provided with a plurality of splits 10 at one end with the first inclined surface 8. The splits 10 are distributed at equal intervals. Due to the design of the splits 10, when the first inclined surface 8 contacts the second inclined surface 9, the first inclined surface 8 will squeeze the second inclined surface 9, so that the inner wall of the second inclined surface 9 is closely fitted with the outer wall of the second rod 5, thereby pressing and fixing the second rod 5, so that the second rod 5 is fixed in the first rod 4. When the first inclined surface 8 contacts the second inclined surface 9, the first inclined surface 8 will squeeze the second inclined surface 9, so that the inner wall of the second inclined surface 9 is closely fitted with the outer wall of the second rod 5, thereby pressing and fixing the second rod 5, so that the second rod 5 is fixed in the first rod 4. When the first bevel 8 is separated from the second bevel 9, the first bevel 8 will loosen the second bevel 9, so that the inner wall of the second bevel 9 is no longer tightly fitted with the outer wall of the second rod 5, thereby unlocking the second rod 5, so that the second rod 5 can move in the first rod 4, and the length of the rake rod 1 can be adjusted.

[0031] Please refer to Figure 1 , 4-5, a folding assembly is provided between the folding rod 2 and the second rod 5, the folding member 2 includes a connecting member 11 and a folding member 2 that can rotate relative to the connecting member 11, the folding member 2 is fixedly connected to the folding rod 2 by a fastener (or glue), the connecting member 11 is fixedly connected to the second rod 5 by a fastener (or glue), the connecting member 11 and the bottom end of the folding member 2 are movably connected together by a connecting shaft 13, that is, the folding member 2 can be rotated and folded around the connecting shaft 13. Specifically, a connecting head 14 is provided at the top of the connecting member 11, the connecting head 14 and the connecting member 11 are an integrated structure, a threaded through hole is provided inside the connecting head 14, a threaded locking member 15 is installed in the threaded through hole, and an annular groove 16 is provided inside the threaded locking member 15; a semicircular through hole 17 is provided at the top of the folding member 2, and the semicircular through hole 17 is used in conjunction with the connecting head 14; a crescent clamp 18 is provided at the top of the connecting member 11 and the folding member 2, and the two crescent clamps 18 are connected together to form a ring and used in conjunction with the annular groove 16; through By rotating the threaded locking piece 15, the threaded locking piece 15 will rise or fall in the threaded through hole of the connecting head 14. When the threaded locking piece 15 rises or falls, the annular groove 16 will also rise and fall. When the crescent clamp head 18 is inserted into the annular groove 16, the folding piece 2 will remain stable with the connecting piece 11, the folding piece 2 cannot rotate, and the wire rake is in an extended state and can be used normally; when the crescent clamp head 18 is separated from the annular groove 16, the folding piece 2 can rotate around the connecting shaft 13, thereby achieving the purpose of folding, which is convenient for storage, transportation and carrying.

[0032] The utility model is a telescopic and foldable wire rake, and its working principle is described in conjunction with the accompanying drawings:

[0033] When the length of the rake rod 1 needs to be adjusted, it is only necessary to rotate the movable sleeve 7 so that the second inclined surface 9 moves away from the first inclined surface 8 to release the lock on the second rod 5. At this time, the user can telescope the second rod 5. After the adjustment is completed, the movable sleeve 7 is rotated in the opposite direction so that the second inclined surface 9 moves close to the first inclined surface 8 to lock the second rod 5, thereby completing the fixation of the second rod 5.

[0034] When it is necessary to store or transport, the second rod 5 only needs to be retracted to the shortest position, and then the threaded locking member 15 is loosened to separate the annular groove 16 from the crescent clamp 18. At this time, the folding rod 2 (folding member 2) can be folded along the second rod 5 (connecting member 11). After retraction and folding, the space occupied by the wire rake will become smaller, which is convenient for transportation and storage.
