DETAILED DESCRIPTION

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0024] Two movable cavities 301 are provided inside both sides of the support plate 3, and first springs 302 are fixedly installed inside the four movable cavities 301. Fixed rods 303 are fixedly installed at one end of the four first springs 302. When the fixed rods 303 are retracted into the movable cavities 301, they will squeeze the first springs 302.

[0025] A driving cavity 304 is provided inside both sides of the support plate 3, and a rotating rod 305 is movably installed inside the two driving cavities 304. The outer surfaces of the two rotating rods 305 are wrapped with traction ropes 306, and the two ends of the two traction ropes 306 are respectively fixedly connected to the four fixed rods 303. When the rotating rod 305 rotates, the traction rope 306 can be wrapped around the outer surface of the rotating rod 305, and then the two fixed rods 303 can be pulled to move and retract into the movable cavity 301.

[0026] A locking plate 308 is fixedly installed on the top surface of the two rotating rods 305, and a locking hole 309 is opened on one side of the two locking plates 308. A plurality of fixing holes 310 are opened on both sides of the top surface of the support plate 3. By inserting bolts into the overlapping locking holes 309 and fixing holes 310, the locking plates 308 can be prevented from rotating. A limiting hole 307 is opened on one side of the four fixing rods 303.

[0027] A connecting frame 101 is fixedly installed on both sides of the two support frames 1, and telescopic sleeves 102 are fixedly installed on the outer surfaces of the four connecting frames 101. Second springs 103 are fixedly installed inside the four telescopic sleeves 102. Limiting rods 104 are fixedly installed at one end of the four second springs 103, and pull rods 105 are fixedly installed at one end of the four limiting rods 104. When the user pulls the pull rod 105, the limiting rod 104 can be moved to squeeze the second spring 103.

[0028] Place the support plate 3 on the outer surfaces of the two support rods 2, and the first spring 302 can push the fixing rod 303 to insert it into the connecting frame 101, and the second spring 103 can push the limiting rod 104 to insert it into the limiting hole 307, and pull the pull rod 105 so that the limiting rod 104 squeezes the second spring 103 until the limiting rod 104 is pulled out of the limiting hole 307, and the fixing rod 303 can be pulled out of the connecting frame 101.

[0029] Four fixing rings 311 are movably installed on the bottom surface of the support plate 3, and a connecting plate 313 is fixedly installed on one side of the four fixing rings 311, and a connecting hole 315 is opened on one side of the four connecting plates 313. Four locking rods 314 are movably installed on the bottom surface of the support plate 3, and the locking rods 314 can rotate. When the locking rods 314 pass through the connecting holes 315 and rotate the locking rods 314, the fixing rings 311 can be prevented from continuing to rotate. A connecting rod 312 is fixedly installed on one side of the four fixing rings 311.

[0030] Two support holes 201 are provided on the outer surfaces of the two support rods 2. When the support plate 3 is placed on the outer surfaces of the two support rods 2, the four fixing rings 311 can be rotated to insert the connecting rod 312 into the support hole 201 until the locking rod 314 passes through the connecting hole 315, and the locking rod 314 is rotated to prevent the fixing ring 311 from continuing to rotate. When the support plate 3 needs to be removed, the locking rod 314 is rotated to pull it out of the connecting hole 315, and the fixing ring 311 can be rotated to pull the connecting rod 312 out of the support hole 201.

[0031] The working principle of the utility model is as follows: first, the support plate 3 is placed on the outer surfaces of the two support rods 2, and the four fixing rings 311 can be rotated to insert the connecting rod 312 into the supporting hole 201, until the locking rod 314 passes through the connecting hole 315, and the locking rod 314 is rotated, and then the bolts in the overlapping locking hole 309 and the fixing hole 310 are pulled out, and the first spring 302 can push the fixing rod 303 to insert it into the connecting frame 101, and the user releases the pull rod 105, and the second spring 103 can push the limiting rod 104 to insert it into the limiting hole 307, so that the overlap can be completed. When it needs to be disassembled, the pull rod 105 is pulled again to make the limiting rod 104 move in. The second spring 103 is moved to squeeze the limit rod 104 so that the limit rod 104 is pulled out from the limit hole 307, and then the rotating rod 305 is rotated. When the rotating rod 305 rotates, the traction rope 306 can be wound around the outer surface of the rotating rod 305, and then the two fixing rods 303 can be pulled to move and retract into the movable cavity 301, so that the limit hole 307 can be pulled out from the connecting frame 101. After that, the bolt is reinserted into the overlapping locking hole 309 and the fixing hole 310, and the locking rod 314 is rotated to pull it out from the connecting hole 315, and the fixing ring 311 can be rotated to pull the connecting rod 312 out of the supporting hole 201, so that the disassembly of the support plate 3 is completed.
