The invention has the following structural characteristics and working principle:

(1) the battery 12 directly supplies power to the motor 13, the rotational power of the motor 13 drives the slide bar shaft 16 through the coupler 14, and the slide bar shaft 16 drives the middle pipe driving block 15, so that the middle pipe 3 rotates;

(2) when the device is used, the handle 1 is held by a hand and the forward rotation button 9 is pressed, the motor 13 rotates forward to drive the middle pipe 3 to rotate forward, and the middle pipe 3 rotates rightward and extends axially under the action of the right-handed threads because the external threads of the middle pipe 3 are matched with the internal threads of the large pipe 2 through the right-handed threads; if the small pipes 4 need to be extended out simultaneously, the alpenstock foot brace 5 is inserted on the ground or the other hand holds the foot brace 5; when the middle pipe 3 is rotationally extended, the internal threads of the middle pipe are matched with the external threads of the small pipe 4 through the left-hand threads, and the small pipe 4 is held by hands or inserted on the ground, so that the small pipe 4 can axially extend under the action of the left-hand threads, and one-key control is realized;

(3) when the middle pipe 3 moves, the middle pipe driving block 15 in the middle pipe 3 simultaneously realizes the action of sliding on the slide bar shaft 16, the control of simultaneous change of the rotating distance and the telescopic distance is realized, and the requirement of the structural length is met;

(4) the synchronous axial telescopic movement of the middle pipe 3 and the small pipe 4 is realized, and the movement distances of the left-handed thread and the right-handed thread are the same because the thread pitches of the left-handed thread and the right-handed thread are the same;

(5) the small pipe 4 can be automatically and manually extended, when the middle pipe 3 rotates, if the foot support 5 is held by a hand, the small pipe 4 can do telescopic motion along with the rotation of the middle pipe 3; if the user does not hold the foot support 5 by hands, the small tube 4 can rotate along with the middle tube 3;

(6) the shortest length of the alpenstock in the contraction state is 650mm, and the longest length of the alpenstock in the expansion state is 1350mm, so that the limit distance of axial movement in the expansion state is 1350-; when the alpenstock is stretched, the small pipe 4 can be driven to synchronously do axial motion only by the rotary motion of the middle pipe 3, so that the middle pipe 3 only needs to do the axial motion of 700/2=350 mm; the thread pitch of the left-handed and right-handed thread features is designed to be 10mm, so that the alpenstock can be realized from the shortest state to the longest state only by rotating the motor shaft for 350/10=35 circles at most;

(7) the control chip in the controller 8 controls the revolution of the motor, the revolution of the motor is set to be controlled to be in the range of 0-35 revolutions for forward and reverse reciprocating rotation, and the stretching is rapid;

(8) the alpenstock is extended by pressing the forward button 9 on the controller 8 to drive the motor 13 to rotate forward, the alpenstock is retracted by pressing the reverse button 11 to drive the motor 13 to rotate reversely, and the motor is locked by pressing the locking button 10, so that the operation is simple and convenient;

(9) because the middle pipe driving block 15 fixed on the middle pipe 3 and the slide bar shaft 16 are connected with the motor 13 through the coupler 14, the middle pipe 3 can not rotate when the motor 13 is locked;

(10) when the small tube 4 needs to be fixed, the locking device 6 only needs to rotate clockwise by an angle, and the locking device can lock the small tube 4 to play a role in quick locking.

The technical means disclosed in the invention scheme are not limited to the technical means disclosed in the above embodiments, but also include the technical scheme formed by any combination of the above technical features.
