The locking structure 14 adopts the prior art, which will not be described in detail here. In other embodiments, the push rod can also be a non-telescopic rod. When the non-telescopic rod is in use, the user can store it by directly fixing the non-telescopic rod on the wall. Compared with the telescopic push rod, the non-telescopic rod does not have high requirements for the wire arrangement in the rod body, and the production is simple and convenient.

The push rod 1 is provided with a handle 11 for the operator to hold, and the handle 11 and the housing 5 are respectively located at two ends of the push rod 1 . Both the walking assembly 2 and the battery pack assembly 4 are arranged away from the handle 11 . The handle 11 is disposed on the first shaft portion 12 . The first shaft part 12 has a first end (not labeled) and a second end (not labeled) oppositely arranged, the second end is docked with the second shaft part 13, and the handle 11 is mounted on the first end.

In this embodiment, the control switch 15 is a button 15, and the button 15 can be a push button or a push button. Its working principle and structure adopt the prior art, and will not be described in detail here.

RTK device 3 adopts RTK (Real Time Kinematic) technology. RTK is a satellite navigation technology used to improve the accuracy of positioning data obtained from global satellite navigation systems. It consists of three parts: a base station receiver, a data link, and a rover receiver. A receiver is placed on the base station as a reference station to continuously observe satellites, and send the observed data and station information to the rover in real time through radio transmission equipment. While receiving GPS satellite signals, the GPS receiver of the rover receives the data transmitted by the base station through wireless receiving equipment, and then calculates the three-dimensional coordinates and accuracy of the rover in real time according to the principle of relative positioning. Its principle and calculation method are well known to those skilled in the art, so it will not be described in detail here.

The battery pack assembly 4 can adopt the existing technology, which generally includes: a casing (not numbered), a number of batteries (not numbered) installed in the casing, and a bracket (not numbered) arranged in the casing to support the batteries, and will not be described in detail.

One end of the button includes a cover locking portion. The return spring is located between the button and the push rod 1. The two ends of the return spring abut against the button and the push rod 1 respectively. In the state where no external force is applied, the force of the return spring limits the position of the button so that the cover 6 keeps covering the receiving groove 51.

Specifically, a hook portion 61 is provided on the other side of the cover body 6 opposite to the connecting shaft 7, and a hook portion 61 is provided on the box body 53 to cooperate with the hook portion 61. The buckle portion 54 , the hook portion 61 and the buckle portion 54 form a cover locking portion. When the battery pack assembly 4 is installed, the assembled battery pack assembly 4 is put into the slot body 111, the cover body 6 is turned over to close the receiving slot 51, and the hook portion 61 cooperates with the buckle portion 54 to lock the cover body 6 and the box body portion 53.

The buckle part 54 is connected to the box body part 53 by a rotating shaft 55. The buckle part 54 is provided with a pressing part 541, which is a button. By pressing the pressing part 541, the buckle part 54 is rotated relative to the box body part 53 with the rotating shaft 55 as the axis of rotation, so as to realize the unlocking between the buckle part 54 and the hook part 61. In detail, the buckle portion 54 includes a plate body portion 542 extending along the height direction of the box body portion 53, a bent portion 543 extending obliquely downward from one end of the plate body portion 542 toward the direction of the box body portion 53, and a buckle 544 protruding from the plate body portion 542 toward the box body direction. The buckle portion 54 is formed at an end of the body portion 542 away from the bent portion 543 , and the buckle 544 cooperates with the hook portion 61 to realize locking. The pressing part 541 is located at one end of the buckle 544 and above the buckle 544 , which is the upper end surface of the plate body part 542 . The bending part 543 is connected to the box part 53 through the rotating shaft 55 . The return spring is a torsion spring (not shown) arranged on the rotating shaft, and the buckle part 54 is always attached to the box part 53 when there is no external force acting on the pressing part 541 through the torsion spring, as shown in FIG. 5 . When an external force acts on the pressing part 541 , the buckle part 54 rotates outward relative to the box part 53 about the shaft 55 , and the buckle 544 is separated from the hook part 61 , thereby realizing unlocking, as shown in FIG. 6 .
