The support foot 20 is rotatably connected to the bottom rail 33 and can be rotated and switched between at least a horizontal position (in a standing state) and a vertical position (in a folded state), and of course, the support foot 20 can be tilted. And a locking mechanism capable of locking the support foot 20 at least in the horizontal and vertical positions. There is no diagonal bracing between the table board 10 and the supporting legs 20, so that the table board has a larger moving space and a simpler structure.

The supporting legs 20 are two and symmetrically connected to both ends of the lower cross bar 33. The bottom cross bar 33 is a hollow bar, the ends of the supporting feet 20 are inserted into the bottom cross bar 33, and each supporting foot 20 can independently rotate relative to the bottom cross bar 33. The supporting legs 20 are L-shaped, and the two supporting legs 20 and the lower cross bar 33 form a U-shaped frame. So that the support feet 20 do not interfere with the user's foot placement. And two blocking head sleeves 50, wherein the blocking head sleeves 50 are sleeved on the lower cross bar 33 and cover the connecting positions of the supporting legs 20 and the lower cross bar 33.

The locking mechanism comprises a pin 61 arranged on the supporting foot 20 and a plurality of clamping grooves 62 arranged at intervals along the periphery of the opening of the lower cross bar 33, and the pin 61 is transversely inserted into the clamping grooves 62 to lock the supporting foot 20. The number and location of the slots 62 can be designed based on the angle of inclination that the support foot 20 is intended to lock. The locking mechanism further includes a tension spring 63 disposed in the lower cross bar 33, wherein the tension spring 63 inwardly tensions the two support legs 20, so that the pin 61 is inserted into the slot 62. When the supporting foot 20 needs to be folded, the supporting foot 20 is pulled to the direction that the pin 62 exits the slot 62 against the elastic force of the tension spring 63. The unlocking operation is simple.

The end of the support foot 20 inserted into the lower cross bar 33 is provided with a plug 21, and two ends of the tension spring 63 are respectively connected with the plugs 21 of the two support feet.
