The two ends of the connecting rod 31 are respectively fixedly connected to the front and rear side walls of the inner cavity of the table 2. The outer surface of the connecting rod 31 is fixedly installed with a positioning wheel 32 located inside the connecting frame 3. A mounting rod 33 is rotatably installed between the front and rear side walls of the inner cavity of the connecting frame 3. A gear ring 34 is fixedly installed on the outer surface of the mounting rod 33. Two racks 35 are slidably installed inside the connecting frame 3, which are respectively engaged with the outer surfaces of the gear ring 34. The two racks 35 are respectively connected with locking tongues 36 for fixing the positioning wheel 32 and the protrusion of the table 2, so that the locking tongues 36 can be used to fix the positioning wheel 32 and the protrusion of the table 2. A guide component 37 for limiting the left and right movement trajectory of the two racks 35 is provided inside the connecting frame 3, and a control component for controlling the two locking tongues 36 is provided inside the connecting frame 3.

[0028] Among them, two slots are provided on the outer surface of the positioning wheel 32, and one end of the left locking tongue 36 passes through the slot and extends to the inside of the positioning wheel 32. The angle between the two slots is ninety degrees. The left locking tongue 36 is fixedly connected to the bottom rack 35, which makes it convenient to use the locking tongue 36 to insert into the inside of the slot, thereby fixing the position of the positioning wheel 32 and fixing the left side of the table 2.

[0029] In addition, the guide component 37 includes two guide rods, both of which are fixedly installed inside the connecting frame 3. One end of the two guide rods passes through the two racks 35 respectively, and the inner wall of the rack 35 is slidably connected to the outer surface of the guide rod, thereby limiting the rack 35 to move left and right only on the outer surface of the guide rod.

[0030] By adopting the above technical solution, the moving wire rope 40 is used to drive the top rack 35 to slide to the left, so that the moving top rack 35 drives the gear ring 34 engaged with it to rotate, and the gear ring 34 drives the bottom rack 35 to move to the right, and then the moving bottom rack 35 is used to pull the left lock tongue 36 to the right out of the interior of the positioning wheel 32, thereby releasing the restriction on the positioning wheel 32. The user can then flip the table 2 to fold and store it.

[0031] In the present embodiment, the control component includes a support plate 38 fixedly installed between the front and rear side walls of the inner cavity of the connecting frame 3, a guide sleeve 39 fixedly installed inside the connecting frame 3, and a steel wire rope 40 with one end passing through the guide sleeve 39 and fixedly connected to the right side locking tongue 36 is provided on the outside of the connecting frame 3. The outer surface of the steel wire rope 40 is sleeved with a telescopic spring 41 located on the right side of the support plate 38, the left side of the telescopic spring 41 is fixedly connected to the right side of the support plate 38, and the right side of the telescopic spring 41 is fixedly connected to one end of the right side locking tongue 36, so as to utilize the elasticity of the telescopic spring 41 and squeeze the right side locking tongue 36 to move to the right, thereby fixing the protrusion of the table 2.

[0032] Among them, the outer surface of the wire rope 40 is fixedly connected to a connecting piece, the top of the connecting piece is fixedly connected to the bottom of the top rack 35, one end of the wire rope 40 passes through the support plate 38 and is slidingly connected to the inner wall of the support plate 38, and one end of the wire rope 40 is fixedly connected to a pull ring located outside the connecting frame 3, so that the pull ring can be used to drive the wire rope 40 to move.

[0033] By adopting the above technical solution, the pull ring is pulled downward, so that the pull ring drives the wire rope 40 to move, and then the moving wire rope 40 drives the right lock tongue 36 to move to the left and compresses the telescopic spring 41, thereby releasing the right lock tongue 36 from fixing the protrusion of the table 2.

[0034] In the implementation of this example, the bracket 1 includes a connecting column 12 fixedly installed at the bottom of the connecting frame 3, an external fork frame 11 is provided at the bottom of the connecting column 12, and a plug-in column 13 is fixedly installed at the bottom with one end passing through and extending into the interior of the external fork frame 11. Two positioning balls 141 for fixing the plug-in column 13 are installed inside the external fork frame 11, and a limiting cylinder 142 is slidably installed on the outer surface of the external fork frame 11. The left and right side walls of the inner cavity of the limiting cylinder 142 are fixedly installed with limiting blocks 143 for limiting the position of the positioning ball 141. The outer surface of the external fork frame 11 is rotatably installed with a threaded sleeve 144 threadedly connected to the outer surface of the limiting cylinder 142, and an anti-slip component 145 is installed on the threaded sleeve 144. The pulley 5 is fixedly installed at the bottom of the external fork frame 11, and the connecting frame 3 is fixedly connected to the top of the connecting column 12.

[0035] Among them, installation grooves are opened on the left and right sides of the outer fork frame 11, and one end of the two limit blocks 143 respectively penetrates and extends to the inside of the two installation grooves, and the two positioning balls 141 are respectively installed in the inside of the two installation grooves and one end of the positioning ball 141 penetrates and extends to the plug-in column 13, so that the positioning ball 141 is conveniently squeezed by the limit block 143, so that the positioning ball 141 is embedded in the inside of the plug-in column 13, thereby fixing the height of the bracket 1.

[0036] By adopting the above technical solution, the threaded sleeve 144 is rotated and the limiting cylinder 142 is controlled to move downward, so that the moving limiting cylinder 142 drives the limiting block 143 to move synchronously, thereby releasing the position restriction of the positioning ball 141. Subsequently, by lifting the unfolded table 2 and then rotating the threaded sleeve 144 in the opposite direction, the limiting cylinder 142 is controlled to drive the limiting block 143 to squeeze the positioning ball 141 until the positioning ball 141 is stuck in the plug-in column 13, thereby fixing the height of the bracket 1, and then adjusting the use height of the table 2.

[0037] The working principle of the above embodiment is:

[0038] The user can then turn the table 2 over, then release the wire rope 40 and, under the action of the telescopic spring 41, the two locking tongues 36 move to the opposite side until the left locking tongue 36 is inserted into the positioning wheel 32, thereby fixing the upright table 2 and folding the table 2.
