[0023] Embodiment: Refer to Figures 1-4 The utility model discloses a first embodiment of telescopic tube, which comprises: an inner tube 100 with an inner tube cavity 120 and a plurality of inner tube grooves 144, an outer tube 200 with an outer tube cavity 220 and sleeved outside the inner tube 100, a sleeve part 300 located in the outer tube cavity 220 and sleeved at one end of the inner tube 100, a push button 500 arranged on the outer tube 200 and capable of pushing the inner tube 100 to stretch or retract, a moving part 520 driven by the push button 500, and a rolling member 600 located in one of the inner tube grooves 144 and pushed by the push button 500.

[0024] The inner tube 100 is made of metal material, which is a hollow cylinder and comprises an inner tube recess 140 arranged on the top end and extending along the length direction of the inner tube 100. The inner tube grooves 144 are arranged on the inner tube recess 140 and spaced along the length direction. The upper end of the inner tube groove 144 is large and the lower end is small, which is formed by stamping. The upper end of the inner tube recess 140 is a flat surface.

[0025] The outer tube 200 is a hollow cylinder and comprises an outer tube hole 240 located below the push button 500, which is made of metal material.

[0026] The sleeve part 300 is a one-time injection molding part and hollow inside, which comprises a receiving cavity 320 located at the top end and accommodating the moving part 520, a receiving hole 324 located in the receiving cavity 320 and corresponding to the rolling member 600, and a containing groove 326 arranged between the receiving hole 324 and allowing the rolling member 600 to roll.

[0027] The embodiment also comprises a plug 400 adjacent to one end of the sleeve part 300 and arranged in the inner tube cavity 120.

[0028] The push button 500 comprises a push button claw 504 located at the bottom and capable of passing through the outer tube hole 240, and a contact part located at the top and capable of contacting the user's thumb. The user can push the contact part to reciprocate along the direction parallel to the center of the outer tube 200.

[0029] The moving part 520 is a flat plate, which comprises a claw groove 524 corresponding to the push button claw 504, and a matching groove 526 allowing the rolling member 600 to at least partially enter it through the receiving hole 324. The inner tube groove 144 accommodating the rolling member 600 is located between the receiving hole 324 and the containing groove 326. The claw groove 524 is closer to the containing groove 326 than the matching groove 526.
