When the rectangular storage cabinets 21 are subjected to the force along the desktop panel 1, the two rectangular storage cabinets 21 will produce synchronous and reverse movement, so that the two rectangular storage cabinets 21 will approach or move away from each other. By changing the distance between the two rectangular storage cabinets 21, the optimal use orientation of the desktop panel 1 can be changed.

[0033] For the specific structure of the bidirectional threaded adjustment mechanism 3, please refer to Figure 5 and Figure 6, including a transverse threaded rod 31, two No. 2 fixed bases 35, a No. 1 moving block 311 and a No. 2 moving block 312, wherein the center of the No. 2 fixed base 35 is provided with a central mounting plate 36 of an integrated structure, and the edge of the No. 2 fixed base 35 is provided with two side mounting plates 37 of an integrated structure, and the No. 2 fixed base 35 is provided with a No. 2 shaft body mounting hole 38 at the center of the central mounting plate 36, and the centers of the No. 1 moving block 311 and the No. 2 moving block 312 are provided with internal threaded holes 314, and the No. 1 moving block The first moving block 311 and the second moving block 312 are provided with internal thread structures on the inner circumferential surfaces of the respective internal thread holes 314, and the edges of the first moving block 311 and the second moving block 312 are provided with two shaft limiting sliding holes 315. The positional relationship of the first moving block 311 and the second moving block 312 is symmetrically arranged with respect to the central plane of the central limiting ring structure 32. The middle part of the rod body of the transverse threaded rod 31 is provided with a central limiting ring structure 32 which is an integral structure with the rod body and protrudes toward the periphery. The transverse threaded rod 31 is provided with a central limiting ring structure 32 which is an integral structure with the rod body and protrudes toward the periphery. The outer periphery of the rod body on both sides of the ring structure 32 is respectively provided with a No. 1 external thread structure 33 and a No. 2 external thread structure 34. The two ends of the transverse threaded rod 31 are respectively fixedly installed with a No. 2 rotating shaft 39 and a No. 3 rotating shaft 310. The shaft body of the No. 2 rotating shaft 39 is installed in the No. 2 shaft body mounting hole 38 of one of the No. 2 fixed bases 35 through a bearing. The shaft body of the No. 3 rotating shaft 310 is installed in the No. 2 shaft body mounting hole 38 of another No. 2 fixed base 35 through a bearing. The side mounting plates 37 of the two No. 2 fixed bases 35 are fixed between them. A transverse limiting rod 316 is installed with a limiting sliding hole 315 that passes through the shaft body. The transverse threaded rod 31 is installed inside the internal threaded hole 314 in the No. 1 moving block 311 when the rod body is located in the No. 1 external thread structure 33. The transverse threaded rod 31 is installed inside the internal threaded hole 314 in the No. 2 moving block 312 when the rod body is located in the No. 2 external thread structure 34. The bottom ends of the No. 1 moving block 311 and the No. 2 moving block 312 are respectively provided with bottom fixing plates 313 that are integrally structured therewith and fixedly installed on the tops of the two rectangular storage cabinets 21.

[0034] In order to prevent the torque resistance from being too large and causing the thread structure in the No. 1 external thread structure 33 and the No. 2 external thread structure 34 to be damaged and deformed, please refer to Figure 1 , Figure 2 , Figure 3 , Figure 7 and Figure 8, it is necessary to set up a torque-controllable rotating mechanism 4, which is internally provided with an inner rotating column 45 fixedly installed at the end of the second rotating shaft 39, a horizontal hollow column 41 placed on the outer periphery of the inner rotating column 45 and capable of rotating, an arc-shaped contact plate 413 that abuts against the outer circumference of the inner rotating column 45 and can rotate with the horizontal hollow column 41, and a spiral spring 49 that makes the arc-shaped contact plate 413 abut against the outer circumference of the inner rotating column 45 in the form of elastic pressure. When the hand crank 42 is rotated, the horizontal hollow column 41 and the arc-shaped contact plate 413 will be driven to rotate together, and the maximum static friction between the arc-shaped contact plate 413 and the inner rotating column 45 will drive the inner rotating column 45 to rotate, and then drive the second rotating shaft 39 to rotate. Once one When the resistance of the No. 1 moving block 311 and the No. 2 moving block 312 to the threaded structure during movement is greater than the elastic strength of the coil spring 49, since the coil spring 49 is in a compressed state and the maximum static friction force generated by the coil spring 49 on the arc-shaped contact plate 413 and the inner rotating column 45 is less than the deformation strength of the No. 1 external thread structure 33 and the No. 2 external thread structure 34, the inner rotating column 45 will remain stationary, while the arc-shaped contact plate 413 and the horizontal hollow column 41 can continue to rotate, but the rotation will not cause the pressure on the threaded structure to continue to increase, thereby preventing the occurrence of damage and deformation of the threaded structures in the No. 1 external thread structure 33 and the No. 2 external thread structure 34 due to excessive torque resistance.

[0035] For the specific structure of the torque controllable rotating mechanism 4, please refer to Figure 7 and Figure 8, including a horizontal hollow column 41 and an inner rotating column 45, one end face of the horizontal hollow column 41 is provided with a hand crank 42 deviating from one side of its axis, the interior of the horizontal hollow column 41 is provided with a No. 1 component active cavity 43, and the other end of the horizontal hollow column 41 is provided with a No. 3 shaft body mounting hole 44 connecting the external space and the No. 1 component active cavity 43, the horizontal hollow column 41 is provided with a rotatable inner rotating column 45 in the central area of ​​the No. 1 component active cavity 43, one end of the inner rotating column 45 is provided with a shaft body mounting groove 46 with an inner concave structure, the shaft body of the No. 2 rotating shaft 39 passes through the No. 3 shaft body mounting hole 44, and the end portion is fixedly installed in the interior of the shaft body mounting groove 46, the shaft body of the No. 2 rotating shaft 39 is installed in the interior of the No. 3 shaft body mounting hole 44 through a bearing, and the circumferential surface of the horizontal hollow column 41 is provided with a plurality of cylindrical protrusion structures 47 which are integrally formed with it and are in an annular array, each of the cylindrical protrusion structures 4 7 are provided with a second component movable cavity 48, one end of the second component movable cavity 48 is provided with a rod body through hole 411 connected to the circumferential side of the first component movable cavity 43, the cylindrical protrusion structure 47 is provided with an inner movable plate 410 capable of axial movement along the second component movable cavity 48, and the inner movable plate 410 is fixedly installed with a rod body through hole 411 and extending to a first component movable cavity 43 at the end facing the rod body through hole 411. An axial telescopic rod 412 is inside the movable cavity 43 of component No. 1, and a coil spring 49 is placed on the other end face of the inner movable plate 410. An arc-shaped contact plate 413 that abuts against the outer circumference of the inner rotating column 45 is fixedly installed on one end of the axial telescopic rod 412 located inside the movable cavity 43 of component No. 1. When the arc-shaped contact plate 413 abuts against the outer circumference of the inner rotating column 45, a gap exists between the inner movable plate 410 and the end face of the movable cavity 48 of component No. 2.

[0036] The specific working principle of the present invention is that when the position relationship needs to be adjusted, when the hand crank 42 is rotated, the horizontal hollow column 41 and the arc-shaped contact plate 413 will be driven to rotate together, and the maximum static friction between the arc-shaped contact plate 413 and the inner rotating column 45 will drive the inner rotating column 45 to rotate, thereby driving the second rotating shaft 39 to rotate;

[0037] When the No. 2 rotating shaft 39 rotates, it will drive the transverse threaded rod 31 to rotate. Since the spiral direction of the No. 1 external thread structure 33 is opposite to the spiral direction of the No. 2 external thread structure 34, and the internal thread structure inside the internal thread hole 314 in the No. 1 moving block 311 matches the external thread structure of the No. 1 external thread structure 33, and the internal thread structure inside the internal thread hole 314 in the No. 2 moving block 312 matches the external thread structure of the No. 2 external thread structure 34, the No. 1 moving block 311 and the No. 2 moving block 312 will produce synchronous and reverse movements, and the No. 1 moving block 311 and the No. 2 moving block 312 will drive the two rectangular storage cabinets 21 to move. When the rectangular storage cabinets 21 are subjected to the force along the desktop panel 1, the two rectangular storage cabinets 21 will produce synchronous and reverse movement, so that the two rectangular storage cabinets 21 will move closer to or farther away from each other. By changing the distance between the two rectangular storage cabinets 21, the optimal use orientation of the desktop panel 1 can be changed.

[0038] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
