For example, described detachable support bar can be pegged graft by last strut 2, middle strut 4 and lower supporting rod 6 these 3 joint support bar sections and be formed (referring to Fig. 1 and Fig. 2), and in the same plane.The link of the support bar section of pegging graft is respectively equipped with the plug and the slot 14 of mutual coupling mutually, forms the connecting interface 3 on the support bar section, and plug is inserted slot, promptly can realize interconnecting.Firm for what guarantee to connect, can also be provided with fastening or detent mechanism/structure is fixed.
Can be provided with the Sopwith staff 5 that shows height on the described support bar.
Referring to Fig. 4, described bracket base can comprise a base plate 24 and two support plates 25, and described two support plates are installed in the two ends of described base plate respectively, and vertical with described base plate.Described support plate is used for kiss the earth during use, forms bigger Area of bearing thus, guarantees the stability of support.
Can adopt the mode of grafting to connect between described support plate and the base plate, perhaps adopt other connected modes of being convenient to arbitrarily dismantle to be connected, form dismountable structure, so that carry and deposit with assembling.
The connecting portion of described support plate and base plate can be provided with fixing button or fastening bolt 22, and after both pegged graft, be tightened button or fastening bolt were so that make connection more firm.
Can be provided with level meter 20 on the described base plate, so that carry out horizontal alignment.Described level meter also can be installed in other suitable positions, on the platform sidewall of for example serving a ball.
The bottom at described each support plate two ends all can be provided with the adjusting knob of downward extension or regulate bolt 23.Turn adjusting knob or adjusting bolt can change the length that it extends out from support plate, so that the horizontality of calibration base.
Described bracket base for example is provided with upwardly extending plug 21 at the base plate middle part with also adopting inserting mode to connect between the support bar, is provided with the slot supporting with this plug in the support bar bottom.
Described support bar can be provided with the slotted hole that holds thimble, and this slotted hole is opened on the top of support bar, and when support bar adopted 3 joint structures, the described slotted hole that holds thimble was arranged on strut.
Described service thimble is positioned at described slotted hole, and the bottom of this thimble is provided with thimble handle 13, and described thimble handle inner end is fixedly connected with described thimble, and the handle groove of leaving on the slotted hole sidewall is passed in the outer end, is exposed at described support bar outside.Upwards promote the thimble handle, just can drive thimble and move up, so that the service platform trap that will be positioned at above the thimble starts.
Described service platform is with adopting any dismountable connected mode to connect between the described support bar, for example pegging graft is connected with bolt.Described supporting bar top can be provided with brace 11, can be provided with connecting hole 15 on the described service platform rear wall, adopt bolt to pass corresponding connecting hole on connecting hole on the described service platform rear wall and the described brace, screw, just can realize both connections with nut.
