Referring to fig. 1-4, the present invention provides a technical solution:

the utility model provides an economic management specialty combination chi, including two limiting plates 6 and inserted bar 3, the both ends at inserted bar 3 are installed respectively to two limiting plates 6, two limiting plates 6 are connected with rings 7 through the stay cord jointly, the movable sleeve is equipped with a plurality of connecting pieces 1 on the inserted bar 3, the one end of every connecting piece 1 is all rotated and is connected with drawing rule 2, connecting piece 1 deviates from the one end of running-on 9 and installs damping pivot 8, connecting plate 4 is installed to damping pivot 8's tip, a plurality of screw holes have been seted up to the symmetry on the connecting plate 4, connecting plate 4 passes through screw and 2 fixed connection of drawing rule.

When being connected connecting piece 1 and drawing rule 2, have planar one end with connecting plate 4 laminating at the drawing rule, then with the screw with connecting plate 4 be connected to drawing rule 2 on, damping pivot 8 makes between connecting piece 1 and the drawing rule 2 can relative rotation, the angle after the rotation also can be fixed at any time, can not rotate the influence at will and carry.

Connecting piece 1 deviates from the one end of drawing rule 2 and sets up the cuff 9 of mutually supporting with inserted bar 3, and two installing ports 12 have been seted up to the symmetry on the inside wall of cuff 9, all installs spring 13 on the inner wall of two installing ports 12, and the equal fixedly connected with stopper 10 of tip of two springs 13, the bevel connection towards cuff 9 one side has all been seted up to the one end that two stoppers 10 are relative. The connecting piece 1 is sleeved on the inserting rod 3 through the sleeve opening 9, the inclined opening towards the outer side is formed in the two limiting blocks 10, therefore, in the process of sleeving, the inserting rod 3 can extrude the limiting blocks 10 into the mounting opening 12, the connecting piece 1 is completely sleeved on the inserting rod 3, the limiting blocks 10 receive the elastic force of the springs 13 to re-enter the sleeve opening 9 at the moment, the inserting rods 3 are clamped on the inner side by the two limiting blocks 10, the clamping of the connecting piece 1 is realized, the connecting piece 1 can still freely rotate, and the flexibility is high.

Still be equipped with the dismantlement structure on connecting piece 1, the dismantlement structure includes pull rod 14 and

depression bar

16, 14 fixed connection of pull rod is at the afterbody of stopper 10, gear groove 11 has all been seted up to the both sides of connecting piece 1, gear groove 11's inside rotation installs transfer gear 15, it is equipped with depression bar 16 to insert on the gear groove 11, pull rod 14 and depression bar 16 use transfer gear 15 to set up relatively as the center, all set up the tooth's socket with 15 intermeshing of transfer gear on pull rod 14 and the depression bar 16, button 5 is installed on depression bar 16's top, depression bar 16's both sides all are equipped with the curb plate, set up the spout of mutually supporting with the curb plate on the inside wall of gear groove 11, the setting up of curb plate makes depression bar 16 can be steadily at 11.

The working principle is as follows: when drawing rule 2 need be taken, press the button 5 on corresponding connecting piece 1 both sides, depression bar 16 is pressed into gear groove 11, because transfer gear 15 all meshes with depression bar 16 and pull rod 14, and the two is in relative position simultaneously, so the activity of depression bar 16 can make pull rod 14 move along opposite direction to make pull rod 14 drive stopper 10 withdraw in installing port 12, can take off connecting piece 1 from inserted bar 3 this moment.
