[0031] The ratchet structure comprises ratchet teeth 61 arranged on the knob 5 and reverse stop teeth 62 fixed on the mountaineering pole handle 1, and the reverse stop teeth 62 are matched with the ratchet teeth 61. When the ratchet teeth 61 and the reverse stop teeth 62 are combined, the knob 5 can only rotate in one direction.

[0032] The center of the winding disc 3 is provided with an assembly shaft 3a, and the knob 5 is axially assembled on the assembly shaft 3a. The knob 5 moves axially along the assembly shaft 3a, and the assembly shaft 3a plays a guiding role.

[0033] First guide strips 51 are arranged at intervals on the knob 5, first guide grooves 51a are formed between adjacent first guide strips 51, second guide strips 31 are arranged on the winding disc 3 and matched with the first guide grooves 51a, and second guide grooves 31a are formed between adjacent second guide strips 31.

[0034] The end of the first guide strip 51 is provided with a guide angle 51b.

[0035] The first guide strip 51 is arranged at intervals, the second guide strip 31 is arranged at intervals, the connection of the knob 5 and the winding disc 3 is realized through the cooperation of the first guide strip 51 and the second guide groove 31a, and the force transmission is realized by the first guide strip 51 and the second guide strip 31, so that the purpose of rotating the winding disc 3 by the knob 5 is realized.

[0036] The side of the hiking stick handle 1 is provided with a groove 11, the winding disc 3 is arranged in the groove 11, and at least one half of the thickness of the knob 5 is arranged outside the groove 11. In this way, the structure is more compact, and the knob 5 arranged outside the groove 11 makes the tightening operation more convenient. Figure 6 As shown in the embodiment, the hiking stick handle 1 is a right-handed stick, the knob 5 is arranged on the left side of the hiking stick handle 1, so that when the user holds the stick with the right hand, the right thumb is just located at the position of the knob 5, the knob 5 can be conveniently rotated by the thumb to realize the tightening of the wrist strap, and the single-handed operation is realized. The structure of the left-handed stick is mirror-symmetrical to the right-handed stick, that is, the knob 5 is arranged on the right side of the hiking stick handle 1.

[0037] The hiking stick handle 1 is provided with a protruding part 12, and the entrances of the first threading channel 1a and the second threading channel 1b are arranged on the protruding part 12. In this way, the entrances of the first threading channel 1a and the second threading channel 1b can be aligned with the winding disc 3, and the orderly winding of the connecting rope is facilitated.

[0038] The hiking stick handle 1 is provided with a containing groove 13, and the first connecting rope 41 and the second connecting rope 42 do not extend out of the containing groove 13. The containing groove 13 can avoid the exposure of the connecting rope, improve the appearance, and in addition, the connecting rope generally adopts a thin nylon rope or a steel wire rope to support, and has a certain risk of scratching in the tightened state. Arranging the connecting rope in the containing groove 13 can reduce the risk.

[0039] The knob 5 is provided with an anti-skid groove 5a on the outer periphery. The anti-skid groove 5a can improve the friction and facilitate the rotation of the knob 5.

[0040] Working principle:

[0041] The hiking stick wrist strap tightening structure of the utility model mainly includes a hiking stick handle 1, a wrist strap 2, a winding disc 3, a first connecting rope 41, a second connecting rope 42 and a knob 5, the one-way rotation of the knob 5 is realized by the ratchet structure arranged between the knob 5 and the hiking stick handle 1, the winding disc 3 is driven to rotate through the transmission of the knob 5 and the winding disc 3, and the tightening function of the wrist strap is realized.

[0042] Specifically, the user wears the wrist strap 2 on the wrist and holds the hiking pole handle 1 to hold the pole. When it is necessary to tighten the wrist strap 2, the knob 5 is combined with the second guide groove 31a on the winding disc 3 through the cooperation of the first guide strip 51 and the second guide groove 31a, that is, the first guide strip 51 is inserted into the corresponding second guide groove 31a, so that the knob 5 is combined with the winding disc 3, and at the same time, the ratchet teeth 61 of the knob 5 are combined with the reverse stop teeth 62 on the hiking pole handle 1, at this time, the knob 5 can only rotate in one direction. When tightening the wrist strap 2, only the knob 5 needs to be rotated, and with the rotation of the knob 5, the winding disc 3 is driven to rotate, thereby increasing the winding length of the first connecting rope 41 and the second connecting rope 42 on the winding disc 3, thereby achieving the purpose of tightening the wrist strap 2. The tightening structure of the utility model, the first connecting rope 41 and the second connecting rope 42 are independently arranged in the first threading channel 1a and the second threading channel 1b, which can avoid the cross knot between the first connecting rope 41 and the second connecting rope 42, and ensure that the tightening structure can normally operate.

[0043] When it is necessary to loosen the wrist strap 2, the knob 5 is axially moved outward, so that the first guide strip 51 of the knob 5 is separated from the second guide groove 31a on the winding disc 3, that is, the knob 5 is separated from the winding disc 3, and at the same time, the ratchet teeth 61 of the knob 5 are separated from the reverse stop teeth 62 on the hiking pole handle 1, at this time, the winding disc 3 loses the obstruction of the ratchet structure, and can be reversely rotated to release the line, at this time, the knob 5 is in an idle state. After loosening is completed, the knob 5 is pushed inward, so that the knob 5 is combined with the winding disc 3 again, and the tightening operation can be performed again.

[0044] The above is only the preferred embodiment of the utility model, and does not limit the implementation mode and protection scope of the utility model, and for those skilled in the art, it should be realized that the scheme obtained by equivalent replacement and obvious changes of the utility model specification and drawing contents should be included in the protection scope of the utility model.
