[0017] The following describes the present utility model in detail with reference to the drawings and specific embodiments.

[0018] As shown in the attached Figures 1-5 A self-locking folding handle shown in the figure includes a handle 1. One end of the handle 1 is rotatably installed with a connecting handle 2 for connecting the walking stick rod. A gear locking structure for locking the relative rotation of the handle 1 and the connecting handle 2 at a preset gear is installed in the handle 1. The gear locking structure includes a lock rod 3 slidably installed in the handle 1 and two lock grooves 4 provided on the connecting handle 2. The two lock grooves 4 are separated by 90° and respectively correspond to two gears, namely the horizontal unfolded state gear and the vertical folded state gear of the handle 1.

[0019] A chute 5 is provided inside the handle 1. The chute 5 includes a narrow-diameter portion 6 with a relatively small inner diameter and a wide-diameter portion 7 with a relatively large inner diameter. The locking rod 3 includes a rod portion 8 and a pin portion 9 fixedly provided at one end of the rod portion 8. A pin head 10 adapted to be inserted into the locking groove 4 is fixedly installed on the pin portion 9. The diameter of the rod portion 8 is adapted to the narrow-diameter portion 6, and the pin portion 9 is adapted to the wide-diameter portion 7. A return spring 11 is provided at a position corresponding to the locking rod 3 and the handle 1 inside the wide-diameter portion 7. One end of the return spring 11 contacts the pin portion 9, and the other end contacts the end of the side wall of the narrow-diameter portion 6, so that the elastic deformation recovery of the return spring 11 can drive the locking rod 3 to be inserted into the locking groove 4. At the other end of the locking rod 3 relative to the pin portion 9, a pulling handle portion 12 is fixedly installed by threaded connection. The pulling handle portion 12 is provided with a pull ring 13, and the pull ring 13 protrudes outside the handle 1 to facilitate unlocking the gear locking of the connecting handle 2 by pulling the pull ring 13. An auxiliary structure such as a pull rope can also be tied to the pull ring 13 to more conveniently pull the pull ring 13.

[0020] As a preferred embodiment, a U-shaped fork 14 is fixedly installed in the chute 5 of the handle 1, and the pin portion 9 of the locking rod 3 passes through the axis of the U-shaped fork 14; one end of the connecting handle 2 is rotatably installed inside the U-shaped fork 14 through a rotating shaft passing through the side walls on both sides of the U-shaped fork 14. Two locking grooves 4 are arranged on the connecting handle 2 in an arc distribution centered on the rotating shaft. A positioning protrusion 15 is provided on the other side of the connecting handle 2 relative to the handle 1, and the handle 1 is provided with a positioning groove 16 that matches and inlays the positioning protrusion 15. A plurality of semi-cylindrical fixing protrusions 17 are uniformly arranged along the circumference at the other end of the connecting handle 2 relative to the handle 1 to improve the connection stability between the connecting handle 2 and the walking stick rod. The upper surface of the handle 1 is provided with anti-slip grip lines 18, and the lower surface of the handle 1 is provided with finger grooves 19 adapted to the fingers.

[0021] The self-locking folding handle provided in this embodiment can be used in cooperation with the walking stick rod of a conventional hiking pole. When the handle 1 is in a horizontally unfolded state, the handle 1 and the walking stick rod are perpendicular to each other, forming an "L" shape and can be used as a walking stick; when it is necessary to use it as a hiking pole or for storage, the pull ring 13 can be pulled. The locking rod 3 and the pin head 10 are driven to slide through the pull ring 13, and the pin head 10 leaves the locking groove 4. At this time, the return spring 11 is compressed. Rotate the handle 1 upward to a vertical state. The locking rod 3 slides closer to the connecting handle 2 under the action of the return spring 11, and at the same time the pin head 10 is inserted into another locking groove 4 to re-lock the position of the handle 1. At this time, the handle 1 and the walking stick rod are on the same straight line and can be used as a grip or a hiking pole. Moreover, the straight-line form occupies less space than the "L" form, which is convenient for storage. Similarly, pulling the pull ring 13 can unlock the handle 1 and rotate the handle 1 downward to restore it to the "L" form.

[0022] The above-described embodiments merely represent one implementation mode of the present utility model. The description thereof is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several modifications and improvements can still be made, and these all fall within the protection scope of the present utility model. Therefore, the protection scope of the patent of the present utility model shall be subject to the appended claims.
