The connection mode between the locking device 8 and other telescopic tubes is the same as the connection mode between the primary telescopic tube 2 , the locking device 8 and the middle telescopic tube 3 .

The working principle of the present invention is as follows: when in use, if the clamping function is not needed, the two clamping arms 501 can be rotated to make the buckle column 502 buckle on the buckle platform 504, so that the two clamping arms 501 are fixed, and the whole device is in a retracted state, which can be used as a walking stick, and the screw protection frame 602 can protect the screw 603 from being bumped and hung. If the length of the device needs to be extended, the middle telescopic tube 3 can be pulled out. When it is pulled to a suitable length, the middle telescopic tube 3 is rotated to drive the lock. The tightening head 801 rotates, and the eccentric boss shaft 804 on the locking head 801 rotates in the locking ring 802, and the locking ring 802 is buckled in the inner wall positioning groove 201 by the positioning slider 805 and is circumferentially fixed and does not rotate, so that the eccentric boss shaft 804 lifts the locking ring 802 to tighten it and press it on the primary telescopic tube 2, thereby realizing the locking between the primary telescopic tube 2 and the middle telescopic tube 3. The locking method between other tube sections is the same, and when contraction is required, it only needs to be rotated in the opposite direction. If the clamping function is needed, the clamping arm 501 can be released from the buckle platform 504, and the screw nut slider 604 slidably installed in the screw nut slot 503 can be threadedly installed on the screw 603, and then the motor 605 can be controlled to rotate forward and reversely through the control button 7. The rotation of the motor 605 drives the driven bevel gear 607 through the active bevel gear 606, thereby driving the screw 603 to rotate. The rotation of the screw 603 causes the screw nut slider 604 to move on the screw 603, and the screw nut slider 604 slides in the screw nut slot 503 and pulls the clamping arm 501 to rotate around the rotating connecting platform 505, thereby realizing the clamping or loosening state of the two clamping heads 506. The clamping head 506 is installed in a ball hinge manner, and a spherical groove and a strip groove are provided on it, so that it can clamp fruits, light bulbs, mobile phones, etc., so that it can be used to pick fruits, install light bulbs at a higher position, or be used as a selfie stick. When the clamping arm 501 needs to be retracted, the lead screw nut slider 604 needs to be disconnected from the lead screw 604 , and then the buckle column 502 is buckled onto the buckle platform 504 .
