Adjustable stick-like sport apparatus

Abstract

An adjustable stick-like sport apparatus has an outer tube and a stick, the outer tube has an opening. The stick slidably mounted in the outer tube and has an extension portion formed in one end and inserted into the outer tube. Two nipping members encircle the extension portion, are engaged with the extension portion and are mounted slidably in the outer tube. When the user rotates the stick with the extension portion, the nipping members are stable relative to the extension portion. The sticks may extend out of or retract in the outer tube to vary a length of the adjustable stick-like sport apparatus. After the length is adjusted, reversely rotating the stick causes the two nipping members to tightly abut the outer tube to fix the length of the adjustable stick-like sport apparatus.

1 . An adjustable stick-like sport apparatus comprising:
 an outer tube having an outer wall and an inner wall, one end of the outer tube having an opening and a runner defined in the inner wall of the outer tube, communicating with the opening and having a wave-like cross section;   a stick having a first end and a second end mounted slidably into the outer tube, an extension portion formed on the second end of the stick, being tapered, an outer thread defined on the extension portion and a flange radially extending out from the distal end of the extension portion; and   two nipping members being semicircular, encircling the extension portion and mounted slidably in the runner in the outer tube and each nipping member having an inner surface, an inner thread defined on the inner surface and engaged with the outer thread of the extension portion and a wave-like outer cross section corresponding to the wave-like cross section of the runner.   
   
   
       2 . The adjustable stick-like sport apparatus as claimed in  claim 1 , wherein a curved groove is defined in a middle of each nipping member, and a resilient ring is mounted in the curved grooves in the nipping members and binding the nipping members and the extension portion together. 
   
   
       3 . The adjustable stick-like sport apparatus as claimed in  claim 1 , wherein the sport pole is a golf club, the first end of the stick is mounted with a golf head, and a handle is mounted on the outer wall of the outer tube. 
   
   
       4 . The adjustable stick-like sport apparatus as claimed in  claim 1 , wherein the adjustable stick-like sport apparatus is a baseball stand and has a seat mounted on the first end of the stick and a base mounted under the outer tube.
