[0023] It should be noted that: gear plate 3 and fixed frame 11 both sides both ends sliding connection, for the subsequent power transmission and movement provides the basic sliding track.When drive part acts on lifting frame 34, lifting frame 34 will drive synchronous motion with the lifting rod 35 connected thereto. Since the bottom of the lifting rod 35 is connected with the top of the gear plate 3, the lifting movement of the lifting rod 35 will directly promote the gear plate 3 to slide on the fixed frame 11 along the predetermined track. The side of two adjacent gear plate 3 relative far away is engaged with gear 31, and gear 31 is rotatably connected with fixed frame 11. When the gear plate 3 slides, based on the meshing transmission principle of gear and rack, the gear 31 engaged therewith will be driven to rotate. The rotation of the gear 31 further drives the retractable rod 32 connected thereto to perform circular motion around the axis of the gear 31. The end of the retractable rod 32 away from the gear 31 is connected with the mobile wheel 33, and the circular motion of the retractable rod 32 enables the mobile wheel 33 to realize the retracting and expanding action. When the receiver body 1 needs to be moved, the drive part drives the lifting frame 34 to rise, which drives the gear plate 3 to rise through the lifting rod 35, and then drives the gear 31 to rotate. The mobile wheel 33 expands to the ground along with the retractable rod 32, at which time the mobile wheel 33 can assist the receiver body 1 to move easily on the ground, greatly improving the moving convenience in the detection work. When it is not necessary to move, the drive part drives the lifting frame 34 to descend, which drives the mobile wheel 33 to retract, reducing the space occupied by the tool when stored and not in use, facilitating storage and carrying. The lifting frame 34 is located outside the receiver body 1, which not only serves as a connection for the lifting rod 35, but also plays a protective and stabilizing role for the receiver body 1 to some extent. During the movement, it can ensure that the entire mobile assembly and the receiver body 1 work cooperatively to ensure the stability of the movement. The drive part located on both sides of the top of the fixed frame 11 is the power source for the retracting and moving functions of the entire mobile assembly.
