Detailed Description

For a more intuitive and complete understanding of the technical solution of the present invention, the following non-limiting characteristic description is now performed by combining the drawings of the present invention:

the first embodiment is as follows: as shown in fig. 1 to 6, the supporting stick comprises a bottom rod 1, a telescopic rod 2 and a top rod 3 which are sequentially in sliding fit from bottom to top, the telescopic rod 2 is of a single structure, when the supporting stick is in a contraction state, the bottom rod 1, the telescopic rod 2 and the top rod 3 are sequentially arranged from inside to outside, a handle 4 is fixed at the top end of the top rod 3, a torsion spring 5 is clamped in the top end of the bottom rod 1, one end of the torsion spring 5 is connected with an elastic buckle 6, a first through hole 7 is arranged on the side wall of the top end of the bottom rod 1, a second through hole 8 which corresponds to the first through hole 7 is arranged on the side wall of the bottom end of the telescopic rod 2, and the outer ends of the elastic buckle 6 extend out of the;

be equipped with a hasp 9 between the top of telescopic link 2 and the bottom of ejector pin 3, hasp 9 is opened back ejector pin 3 and telescopic link 2 sliding fit, has the slope 61 with the ejector pin 3 contact after ejector pin 3 moves down on the outer terminal surface of bullet knot 6, and the bottom mounting of telescopic link 2 has a bush 10 that is used for supporting the ejector pin 3 bottom.

The end of the torsion spring 5 connected with the elastic buckle 6 is provided with a convex strip 51, and the inner end of the elastic buckle 6 is opened and provided with a groove 62 for the convex strip 51 to extend into for positioning. The other end of the torsion spring 5 has an elastic arm 52 and abuts against the inner wall of the bottom bar 1. When the snap 6 is pressed to move inward, the torsion spring 5 is compressed.

A first clamping ring 11 positioned below the elastic buckle 6 is fixed on the outer wall of the top end of the bottom rod 1, and a second clamping ring 12 used for blocking the first clamping ring 11 and positioned below the first clamping ring 11 is fixed on the inner wall of the bottom end of the telescopic rod 2. The bottom rod 1, the telescopic rod 2 and the ejector rod 3 are hollow round rods, the positions of the first clamping ring 11 and the second clamping ring 12 correspond to the positions of the elastic buckle 6, namely when the second clamping ring 12 blocks the first clamping ring 11, the elastic buckle 6 can just extend out of the first through hole 7 and the second through hole 8. Of course, because the bottom rod 1 and the telescopic rod 2 are both round, the supporting stick can be folded back and the first through hole 7 is not aligned with the second through hole 8, and at this time, the bottom rod 1 can be rotated until the first through hole 7 is aligned with the second through hole 8, and the elastic buckle 6 can be automatically ejected out rapidly.

In order to conveniently install the first clamping ring 11 and the second clamping ring 12, a first clamping groove 13 for the first clamping ring 11 to be clamped in is arranged on the outer wall of the top end of the bottom rod 1, and a second clamping groove 14 for the second clamping ring 12 to be clamped in is arranged on the inner wall of the bottom end of the telescopic rod 2. The first clamping ring 11 and the second clamping ring 12 are arranged to prevent the bottom rod 1 from being separated from the telescopic rod 2.

As shown in fig. 6, the lock catch 9 is a lock catch commonly used in alpenstock of the prior art, the lock catch 9 is through from top to bottom, the top end of the lock catch 9 is connected with the bottom end of the ejector rod 3, the bottom end of the telescopic rod 2 is connected with the top end of the lock catch 9, the top end of the lock catch 9 is provided with a claw 91, the lock catch 9 is externally provided with a wrench for locking the claw, after the wrench is opened, the claw loosens the ejector rod 3, and the.

The top of the bottom rod 1 is sleeved with a friction plate 15 positioned between the outer wall of the bottom rod 1 and the inner wall of the telescopic rod 2, the middle part of the friction plate 15 protrudes outwards to be in contact with the inner wall of the telescopic rod 2, and the friction plate 15 is positioned above the elastic buckle 6. The friction plate 15 is used for increasing friction force, and the friction plate 15 can also prevent the outer wall of the bottom rod 1 from directly contacting with the inner wall of the telescopic rod 2, so that the telescopic rod 2 and the bottom rod 1 are prevented from being damaged on the surface.

When the supporting stick needs to be folded, the lock catch 9 is opened firstly, the handle 4 is held and the ejector rod 3 is pressed downwards, the ejector rod 3 contacts with the slope 61 of the elastic buckle 6 in the pressing process, the elastic buckle 6 is extruded inwards, the elastic buckle 6 retracts into the telescopic rod 2, the torsion spring 5 is compressed, a limiting structure between the ejector rod 3 and the telescopic rod 2 is eliminated, the ejector rod 3 continuously moves downwards to contact with the bush 10, the ejector rod 3 drives the telescopic rod 2 to move downwards after pressing the bush 10 downwards, the telescopic rod 2 is sleeved outside the ejector rod 3 after moving downwards, the supporting stick is folded, when the supporting stick needs to be opened, the bottom rod 1 is pulled outwards, the telescopic rod 2 is separated from the elastic buckle 6, the elastic buckle 6 extends out and resets through the elasticity of the torsion spring 5, and finally the lock catch 9 is locked, the use is convenient, and the structure is stable after the elastic buckle 6 is adopted for limiting.

Example two: as shown in fig. 7 and 8, the difference between the second embodiment and the first embodiment is that the number of the telescopic rods 2 is two, the inner diameters of the two telescopic rods 2 are different, an "elastic buckle limiting structure" is also adopted between the two telescopic rods 2, the two telescopic rods 2 are in sliding fit, one connecting lock catch 9 is arranged, and the other connecting bottom rod 1 is arranged.

Of course, the above is only a preferred embodiment of the present invention, and not to limit the scope of the present invention, for example, the number of the telescopic rods is three or four, or even more, and all the simple modifications and equivalent structural changes using the contents of the specification and drawings of the present invention should be included in the scope of the present invention.
