By means of the support connecting mechanism arranged between the upper support 3 and the lower support 4, the bolt rod 203 is inserted into the bolt hole 204, the upper positioning column 201 and the lower positioning column 202 are connected as a whole, the upper support 3 and the lower support 4 arranged in the up-down direction are connected, the relative rotation between the upper support 3 and the lower support 4 is prevented, the support as a whole maintains a rectangular structure, and the stability of the support after being unfolded is ensured.

[0026] Further, the inner wall of the upper positioning column 201 and the inner wall of the bolt hole 204 are provided with a guide groove 210, and the outer side of the bolt rod 203 is fixed with a guide strip 209 which is matched with the guide groove 210; the rotation of the bolt rod 203 in the upper positioning column 201 is prevented, the guide strip 209 on the outer side of the bolt rod 203 is matched with the guide groove 210 on the inner side of the bolt hole 204, and the connection reliability of the upper positioning column 201 and the lower positioning column 202 is improved.

[0027] Further, the two ends of the threaded rod 301 are fixed with two limiting stop rings 304. When the support is unfolded, the threaded rod 301 drives the two threaded sliding blocks 303 to move to the two ends, when one end of each of the two threaded sliding blocks 303 is in contact with one end of each of the two limiting stop rings 304, the two threaded sliding blocks 303 cannot continue to move, and thus cannot continue to drive the two upper supports 3 and the two lower supports 4 to continue to rotate, at this time, the two upper supports 3 and the two lower supports 4 can be rotated to the vertical angle.

[0028] Working principle: During use, the support frame is unfolded as a whole. Hexagonal columns are fixed to both ends of the threaded rod 301. Turning the hexagonal columns with a wrench causes the threaded rod 301 to rotate. When the threaded rod 301 rotates, it drives two threaded sliders 303 to move in opposite directions at the same speed through the two symmetrical external threads at both ends. The two threaded sliders 303, through four connecting rods 302, drive one end of each of the two upper supports 3 to rotate in opposite directions at the same speed. The two upper supports 3, in turn, drive the two lower supports 4 to rotate in opposite directions at the same speed. The two upper supports 3 and the two lower supports 4 simultaneously rotate from an inclined angle to a vertical angle. When one end of each of the two threaded sliders 303 is respectively connected to the two... When one end of the limit ring 304 contacts, the two threaded sliders 303 cannot continue to move, thus preventing them from driving the two upper supports 3 and the two lower supports 4 to continue rotating. At this time, the two upper supports 3 and the two lower supports 4 can rotate to a vertical angle and are on the same straight line. The lower crossbeam 1 is supported on the ground, and the two upper supports 3 and the two lower supports 4 lift the upper crossbeam 2 horizontally, thus forming a rectangle between the lower crossbeam 1, the upper crossbeam 2, the two upper supports 3, and the two lower supports 4, thereby unfolding the entire support. The upper side of the upper crossbeam 2 can be used to place equipment such as transformers. To improve the overall stability of the support, the rotating shaft 207 of the transmission mechanism needs to be rotated. The rotating shaft 207 drives the two active bevel gears 208 to rotate. The two active bevel gears 208 drive the two driven bevel gears 206 to rotate synchronously through their teeth. The two driven bevel gears 206 drive the two lead screws 205 to rotate synchronously. The two lead screws 205 drive the two pins 203 to move downward through their threads, so that the pins 203 are inserted into the pin holes 204 inside the lower positioning column 202. Thus, the upper positioning column 201 and the lower positioning column 202 can be connected into a whole through the pins 203, thereby connecting the upper support 3 and the lower support 4 arranged vertically, preventing relative rotation between the upper support 3 and the lower support 4, and thus ensuring the overall stability of the support after it is deployed. To further improve the overall stability of the support, a diagonal bracing positioning mechanism is also set at the diagonal position on the inner side of the support. When the support is unfolded, the upper support 3 will drive the slide rod 102 to extend outward of the piston cylinder 101. The slide rod 102 drives the piston 103 to move inside the piston cylinder 101. The piston 103 squeezes the hydraulic oil at one end of the piston cylinder 101 through the oil hole 106 to the inside of the oil reservoir 104. The other end of the piston cylinder 101 is provided with a second air hole 114, and the other end of the oil reservoir 104 is provided with a first air hole 113. When the piston 103 moves, the other end of the inner side of the piston cylinder 101 can be connected to the outside atmosphere through the second air hole 114. When the hydraulic oil is squeezed into the inside of the oil reservoir 104, the hydraulic oil pushes the piston 2 110 to move and compress the return spring 111. At the same time, the other end of the inner side of the oil reservoir 104 is connected to the outside atmosphere through the first air hole 113. When the support is fully unfolded, the slide rod 102 stops extending outwards, at this time, manually rotate the through shaft 108 in the cutting mechanism, so that it rotates 90°, the through shaft 108 drives the cylindrical valve core 107 to rotate 90°, the cylindrical valve core 107 drives the internal flow channel 109 to rotate 90°, so that the two ends of the flow channel 109 are not aligned with the two oil holes 106, as shown in the figure, so that the two oil holes 106 are blocked by the cylindrical valve core 107, at this time, the hydraulic oil inside one end of the oil storage cylinder 104 and the inside one end of the piston cylinder 101 cannot flow back and forth, so that the piston one 103 and the piston two 110 cannot move back and forth, so that the slide rod 102 cannot be extended and retracted, so as to fix the slide rod 102 and the piston cylinder 101, the slide rod 102 and the piston cylinder 101 can support the upper support 3 and the lower support 4 at the opposite corners, prevent the upper support 3 and the lower support 4 from tilting as a whole, so as to further improve the stability of the support as a whole; Figure 5 When the support is fully unfolded, the slide rod 102 stops extending outwards, at this time, manually rotate the through shaft 108 in the cutting mechanism, so that it rotates 90°, the through shaft 108 drives the cylindrical valve core 107 to rotate 90°, the cylindrical valve core 107 drives the internal flow channel 109 to rotate 90°, so that the two ends of the flow channel 109 are not aligned with the two oil holes 106, as shown in the figure, so that the two oil holes 106 are blocked by the cylindrical valve core 107, at this time, the hydraulic oil inside one end of the oil storage cylinder 104 and the inside one end of the piston cylinder 101 cannot flow back and forth, so that the piston one 103 and the piston two 110 cannot move back and forth, so that the slide rod 102 cannot be extended and retracted, so as to fix the slide rod 102 and the piston cylinder 101, the slide rod 102 and the piston cylinder 101 can support the upper support 3 and the lower support 4 at the opposite corners, prevent the upper support 3 and the lower support 4 from tilting as a whole, so as to further improve the stability of the support as a whole; When the support is fully unfolded, the slide rod 102 stops extending outwards, at this time, manually rotate the through shaft 108 in the cutting mechanism, so that it rotates 90°, the through shaft 108 drives the cylindrical valve core 107 to rotate 90°, the cylindrical valve core 107 drives the internal flow channel 109 to rotate 90°, so that the two ends of the flow channel 109 are not aligned with the two oil holes 106, as shown in the figure, so that the two oil holes 106 are blocked by the cylindrical valve core 107, at this time, the hydraulic oil inside one end of the oil storage cylinder 104 and the inside one end of the piston cylinder 101 cannot flow back and forth, so that the piston one 103 and the piston two 110 cannot move back and forth, so that the slide rod 102 cannot be extended and retracted, so as to fix the slide rod 102 and the piston cylinder 101, the slide rod 102 and the piston cylinder 101 can support the upper support 3 and the lower support 4 at the opposite corners, prevent the upper support 3 and the lower support 4 from tilting as a whole, so as to further improve the stability of the support as a whole; Figure 7 When the support is fully unfolded, the slide rod 102 stops extending outwards, at this time, manually rotate the through shaft 108 in the cutting mechanism, so that it rotates 90°, the through shaft 108 drives the cylindrical valve core 107 to rotate 90°, the cylindrical valve core 107 drives the internal flow channel 109 to rotate 90°, so that the two ends of the flow channel 109 are not aligned with the two oil holes 106, as shown in the figure, so that the two oil holes 106 are blocked by the cylindrical valve core 107, at this time, the hydraulic oil inside one end of the oil storage cylinder 104 and the inside one end of the piston cylinder 101 cannot flow back and forth, so that the piston one 103 and the piston two 110 cannot move back and forth, so that the slide rod 102 cannot be extended and retracted, so as to fix the slide rod 102 and the piston cylinder 101, the slide rod 102 and the piston cylinder 101 can support the upper support 3 and the lower support 4 at the opposite corners, prevent the upper support 3 and the lower support 4 from tilting as a whole, so as to further improve the stability of the support as a whole;
