Further, the walking driving structure 4 of the present invention includes a fixed seat block 41, two driven wheels 44, a driving wheel 43 mounted on the fixed seat block 41 through a fixed shaft 42, the two driven wheels 44 are both connected to the fixed shaft 42 through a support rod 45, the two support rods 45 are located at two sides of the fixed seat block 41, an end of the support rod 45 far away from the driven wheels 44 is connected to the fixed shaft 42 through a torsion spring member, a driving unit for driving the two support rods 45 to rotate around the fixed shaft 42 is disposed at a bottom of the fixed seat block 41, and the rod body 3 is fixedly connected to the fixed seat block 41.
Wherein, the top inner wall contact of action wheel 43 and rail groove 103, two follow driving wheels 44 and the bottom inner wall contact of rail groove 103, action wheel 43 and follow driving wheel 44 all adopt rubber material.
The fixed seat block 41 includes an upper seat 411 and a lower seat 412, the top of the lower seat 412 is connected to the bottom of the upper seat 411 through an elastic connector 413, and the rod 3 is fixedly connected to the lower seat 412.
Further, the driving unit in the present invention may be any linear displacement driving structure in the prior art, but in order to realize the control of a single driving member for multiple functional components, it is preferable that the driving unit is a micro telescopic cylinder 5, a bottom of the micro telescopic cylinder 5 is fixedly connected to the upper seat 411, an end of a piston rod 51 of the micro telescopic cylinder 5 is connected to the support rod 45 through a connecting member 53, and a rod body of the piston rod 51 of the micro telescopic cylinder 5 is connected to the lower seat 412, the micro telescopic cylinder 5 drives the piston rod 51 to move linearly along the width direction of the rail slot 103, the lower seat 412 is driven by the piston rod 51 to contact with the bottom wall of the rail slot 103, so as to fix the lower seat 412, i.e. the fixed rod body 3, and the linear movement of the piston rod 51 along the width direction of the rail slot 103 is also synchronized so that the two support rods 45 rotate downward around the fixed shaft 42 under the traction of the connecting member 53 (the included angle between the two support rods 45 becomes smaller, the two driven wheels 44 are close to each other), thereby achieving the fixing of the position of the whole walking drive structure 4 in the rail groove 103 and the fixing of the rod body 3.
Because the driving wheel 43 and the driven wheel 44 are made of rubber, the linear motion of the piston rod 51 driven by the micro telescopic cylinder 5 can increase the acting force of the driving wheel 43 and the driven wheel 44 on the top wall and the bottom wall of the rail groove 103, so that the driving wheel 43 and the driven wheel 44 can be deformed adaptively;
the deformation increases the contact area between the driving wheel 43 and the driven wheel 44 and the wall surface of the rail groove 103, and the triangular structure formed by the driving wheel, the driven wheel and the two support rods 45 improves the stability of the whole walking and fixing of the walking driving structure 4 in the rail groove 103.
Meanwhile, the stroke of the driving piston rod 51 of the micro telescopic cylinder 5 along the width direction of the rail groove 103 can be controlled by the deformation action of the driving wheel 43 and the driven wheel 44.
Further, in order to realize a wider range of position excursion of the annular lamp holder 2, the rod 3 includes a first rod 31 and a second rod 32, the first rod 31 and the second rod 32 are slidably connected, an end of the second rod 32 far away from the first rod 31 is slidably connected to the annular lamp holder 2, and an end of the first rod 31 far away from the second rod 32 is fixedly connected to the lower base 412.
Further, in order to realize the telescopic control of the first rod 31 and the second rod 32, and without adding an additional independent control structure, a middle seat 414 is disposed between the lower seat 412 and the upper seat 411, the middle seat 414 is connected with the lower seat 412 and the upper seat 411 through a stacked spring or a rubber pad, a penetrating column hole 415 for the piston rod 51 of the micro telescopic cylinder 5 to pass through is vertically disposed in the middle seat 414, an embedding groove 416 is disposed on the inner wall of the penetrating column hole 415 along the length direction of the penetrating column hole 415, a bolt 417 connected with the embedding groove 416 is disposed on the piston rod 51 of the micro telescopic cylinder 5, and the embedding groove 416 and the bolt 417 are in clearance fit.

The specific method for controlling the upper seat 411, the lower seat 412 and the middle seat 414 by the axial stroke action of the piston rod 51 of the micro telescopic cylinder 5 is as follows:
firstly, the piston rod 51 is driven by the micro telescopic cylinder 5 to move axially, the piston rod 51 acts on the lower seat body 412, so that the lower seat body 412 contacts with the bottom wall of the rail groove 103 (at this time, the bolt body 417 does not contact with the bottom of the caulking groove 416), when the micro telescopic cylinder 5 continues to increase the axial stroke of the piston rod 51, the bolt body 417 of the piston rod 51 applies force to the bottom of the caulking groove 417, so that the axial stroke of the piston rod 51 drives the middle seat body 414 to move downwards (the middle seat body 414 is close to the lower seat body 412), and the downward movement of the middle seat body 414 drives the guide rod 34 to move along the length direction of the guide groove 33.
Furthermore, the linear movement of the guiding rod 34 along the length direction of the guiding slot 33 will disconnect the fastener at the end of the guiding rod 34 from the second rod 32, i.e. the fixed connection between the first rod 31 and the second rod 32 is released, so that the first rod 31 and the second rod 32 of one rod can be extended and retracted when the other rod moves along the rail slot 103 in the walking driving structure 4, thereby changing the relative position of the annular lamp holder 2.
It is of course also possible to disconnect both the first rod 31 and the second rod 32 of the two rods 3, and to change the position of the circular lamp base 2 (i.e. in the plane of the strip-shaped rail 1) by moving the travel drive 4 along the rail groove 103.

The installation between the strip-shaped rail body 1 and the bed body is not mainly explained, but in order to realize the height adjustment and installation of the strip-shaped rail body, the invention further comprises at least two longitudinal telescopic supports 6, the telescopic supports 6 can be a telescopic structure in the form of a fishing rod or a two-section sliding rail, the top of each longitudinal telescopic support 6 is connected with the strip-shaped rail body 1 through a clamping mechanism 7, wherein when the strip-shaped rail body 1 only comprises a first rail body 101 and a second rail body 102, the installation positions of the two longitudinal telescopic supports 6 are not limited, when the strip-shaped rail body 1 comprises the first rail body 101, the second rail body 102 and a third rail body 103, the two longitudinal telescopic supports 6 are installed on the second rail body 102, and the longitudinal telescopic supports 6 are mainly used for being fixedly installed with the bed body to fix the position of the strip-shaped rail body 1.
