[0042] In order to enable quick assembly of the telescopic rod assembly and to adjust the length according to actual use, thereby improving the user experience, the present embodiment provides a telescopic rod assembly and a picking tool. Figures 1 to 6 The specific contents of this embodiment are described in detail. It should be noted that the first direction mentioned in this embodiment is Figure 4 The X direction in .

[0043] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 Combination Figure 6 As shown, the telescopic rod assembly includes a first sleeve member 1, a second sleeve member 2, a locking assembly 3 and a latch 4. The inner diameter of the first sleeve member 1 is larger than the outer diameter of the second sleeve member 2. The second sleeve member 2 is inserted into the first sleeve member 1. The first end of the second sleeve member 2 is provided with a first pin hole 21. The locking assembly 3 includes a locking column 31 and at least two arc-shaped members 32. The locking column 31 includes a first column section 311, a second column section 312 and a limit plate 313 connected in sequence. The first column section 311 is provided with a second pin hole 3111. The outer wall surface of the second column section 312 is symmetrically provided with at least two diameter-changing grooves 3121. The bottom of the diameter-changing groove 3121 includes a first surface 31211, a transition arc surface 31212 and a second surface 31213. The first surface 31211 is provided with a second pin hole 3111. The outer diameter of the first surface 31211 is greater than the outer diameter of the second surface 31213. The transition arc surface 31212 is located between the first surface 31211 and the second surface 31213. The outer diameter of the transition arc surface 31212 gradually increases along the direction of the second surface 31213 approaching the first surface 31211. The arc-shaped member 32 is arranged on the limiting plate 313. The inner wall surface of the arc-shaped member 32 is provided with a strip portion 321, and the strip portion 321 abuts against the bottom of the reducing groove 3121. The latch pin 4 is inserted into the first pin hole 21 and the second pin hole 3111.

[0044] The telescopic rod assembly provided by the utility model inserts the first column section 311 of the locking column 31 into the second sleeve member 2, and uses the pin 4 to fix the locking column 31 and the second sleeve member 2 together, and the two arc-shaped members 32 are symmetrically placed on both sides of the second column section 312, and the lower end surface of the arc-shaped member 32 abuts against the limit plate 313, and the strip portion 321 of the arc-shaped member 32 abuts against the second surface 31213 of the groove bottom of the reducing groove 3121, and then the second sleeve member 2 with the locking assembly 3 is inserted into the first sleeve member 1, and at this time, there is a gap between the outer wall surface of the two arc-shaped members 32 and the inner wall surface of the first sleeve member 1. After adjusting the total length of the telescopic rod assembly to a suitable length by pulling and pulling, the second sleeve pipe member 2 is rotated and the lock column 31 is rotated, so that the first surface 31211 of the groove bottom of the reducing groove 3121 abuts against the strip portion 321 of the arc-shaped member 32. Since the outer diameter of the first surface 31211 is greater than the outer diameter of the second surface 31213, the two arc-shaped members 32 can be moved away from each other and tightly abutted against the inner wall surface of the first sleeve pipe member 1, thereby achieving the fixation of the first sleeve pipe member 1 and the second sleeve pipe member 2. By rotating the lock column 31, the outer diameter of the circle formed by the two arc-shaped members 32 can be increased or decreased, thereby achieving the locking or unlocking of the two pipe members, which not only reduces the difficulty of adjusting the length of the telescopic rod assembly, but also shortens the assembly time.

[0046] Optionally, the second limiting portion 22 is an annular carbon fiber pad, and the second limiting portion 22 is sleeved on the second sleeve member 2. The second limiting portion 22 and the second sleeve member 2 can be installed firmly through the interference fit.

[0047] Furthermore, the lock column 31 also includes a stop ring 314, which is disposed between the first column section 311 and the second column section 312, and the port of the first end of the second sleeve member 2 is stopped at the stop ring 314. When the first column section 311 is inserted into the second sleeve member 2, when the stop ring 314 abuts against the port of the first end of the second sleeve member 2, the second pin hole 3111 is just opposite to the first pin hole 21, which facilitates the rapid insertion of the latch pin 4, so that the lock column 31 and the second sleeve member 2 are fixed to each other.

[0048] Furthermore, the outer wall surface of the arc-shaped member 32 is provided with a plurality of first arc-shaped reinforcing ribs 322, and the plurality of first arc-shaped reinforcing ribs 322 are arranged at intervals along the first direction.

[0049] Furthermore, the locking assembly 3 further includes an anti-slip member 33, which is sleeved on the arc-shaped member 32. Since the anti-slip member 33 is provided on the arc-shaped member 32, on the one hand, the arc-shaped member 32 can be prevented from directly rubbing against the inner wall surface of the first sleeve member 1, thereby extending the service life of the arc-shaped member 32; on the other hand, the anti-slip member 33 is in direct contact with the inner wall surface of the first sleeve member 1, thereby increasing the friction resistance between the two.

[0050] Further, the end of the first arc-shaped reinforcement rib 322 is provided with a first hook portion 3221, and the end of the second arc-shaped reinforcement rib 323 is provided with a second hook portion 3231.

The first arc-shaped reinforcement rib 322 is provided in the first arc-shaped groove 331, and the first hook portion 3221 is inserted in the first through hole 3311. The second arc-shaped reinforcement rib 323 is provided in the second arc-shaped groove 332, and the second hook portion 3231 is inserted in the second through hole 3321, so that the anti-slip member 33 not only wraps the first arc-shaped reinforcement rib 322 and the second arc-shaped reinforcement rib 323, but also ensures the wrapping firmness between the anti-slip member 33 and the arc-shaped member 32.

[0051] Furthermore, an anti-skid structure 333 is provided on the outer wall surface of the anti-skid member 33. For example, the anti-skid structure 333 may be, but is not limited to, an anti-skid protrusion or an anti-skid groove, and no further restrictions are made here.

[0052] Optionally, the locking column 31 is hollow inside, and a first opening 315 and a second opening 316 are provided at opposite ends of the locking column 31. In some application scenarios, objects such as cables can be passed through the locking column 31.

[0053] This embodiment also provides a picking tool, which includes the telescopic rod assembly mentioned above. By rotating the locking assembly 3 on the second set of pipe parts 2, the first set of pipe parts 1 and the second set of pipe parts 2 can be assembled and disassembled, which can be quickly assembled to improve the user experience. For example, one end of the picking tool can be but is not limited to a hook or a sickle, and the hook can be used to pick pine cones or the sickle can be used to pick betel nuts.
