Mounting hole, the both sides of leg holding tank are symmetrically provided with lock hole, and nearly bottom land end position is provided with salient point in chair leg holding tank,
The mounting post that cooperation is adapted to mounting hole is distributed with the neighboring of described baffler, and folded table leg includes articulated column, table leg
Overcoat, the table leg inner sleeve with dovetail groove, the rotatable rotation elastic rod being installed in dovetail groove, installed in rotating elastic rod and ladder
It is provided with elastic rod spring between shape groove, described dovetail groove in the circular groove that ammunition feed bar spring is inserted, the articulated column and table leg
Set head is hinged, and described table leg inner sleeve is placed in table leg overcoat；The inside of described articulated column is hollow structure, in articulated column
The circular hole for being provided with and extending along articulated column length direction on end is connected with table leg overcoat, the inner face edge where circular hole is hinged column length
Degree direction is provided with fore-set sliding groove, and the outer surface of articulated column is provided with through hole, and the through hole is connected with inner hollow, and fore-set is slided
Groove is provided with the rotating hole perpendicular with through hole on the whole；
Automatic locking mechanism is provided with described fore-set sliding groove, the automatic locking mechanism is provided with spring including bottom
The slip fore-set of mounting hole, the fore-set spring being installed in spring mounting hole, two be respectively arranged in through hole and with rolling
The clamping block of wheel, the retracting spring being respectively arranged between clamping block and articulated column inner surface, locked flapper, it is fixedly mounted on lock
Determine the torsion spring of baffle plate and articulated column inner surface, the slip fore-set include the sliding shoe of bottom, the push rod on sliding shoe,
The projection on top, the projection is installed in circular hole, and the sliding shoe is installed in fore-set sliding groove, is installed on spring mounting hole
Interior fore-set spring also is located in sliding groove；The locked flapper upper and lower ends are column spinner and are installed in rotating hole, are locked
The middle part of baffle plate is determined for the symmetrical cam of profile and is cooperated with the roller on clamping block, and locked flapper is provided with and push rod
The linked-baffle being engaged.
As an improvement：Described table leg inner sleeve be placed in table leg overcoat and the internal thread by table leg overcoat top with
The tip male thread of table leg inner sleeve is connected, and described elastic rod spring, which is arranged on, to be rotated between elastic rod and dovetail groove and be fixed on
In the circular groove that dovetail groove is provided with, the bottom of described table leg inner sleeve is provided with the spring column mounting groove for placing flexible spring column, and described stretches
Contracting spring column spring is provided with flexible spring column ejection hole, institute installed in flexible between spring column and spring column mounting groove, and in table leg on set
The table leg overcoat stated is provided with table leg fixing hole corresponding with ejection hole, and table is realized by the cooperation of stretch spring column and table leg fixing hole
Spacing fixation after leg stretching.
As an improvement：The upper and lower part of described table leg inner sleeve is distributed with external screw thread, the articulated column and table
