Embodiment
In order to more fully understand the technology contents of the present invention, technical scheme is entered with reference to specific embodiment
One step introduction and explanation, but it is not limited to this.
As shown in Figure 1-2, a kind of combined type coupling bar of the invention, including connection bar body 10, couple the tail of bar body 10
Portion is provided with buckling groove 11, and the head of connection bar body 10 is provided with the nut 13 of thread connection；Connection bar body 10 is additionally provided with axial direction
The rotation stop groove 12 of extension.In connection, connection bar body 10, can be by dismounting work because being provided with rotation stop groove 12 without rotating
Tool rotation nut 13, so as to realize that coupling bar couples to the locking between workpiece.In the present embodiment, also couple in the periphery of nut 13
There is the handle 40 of two-way detachable driving coupling.Handle 40 includes the handle body 41 with coupling the rotation connection of bar body 10,
Nut 13 is provided with the ring tooth-like part 131 being located in handle body 41；Handle body 41 is provided with cavity 42, cavity 42 provided with hinge
It is connected to the bidirectional modulation handle 43 of handle body 41；Bidirectional modulation handle 43 (is fixed on hand provided with hinge hole 431 by being hinged screw 44
In handle body 41), and it is symmetrically set in the reverse engaging piece 432 of the both sides of hinge hole 431 and forward engaging piece 433；Forward engaging piece
433 pushing sections 434 extended to laterally outside handle body 41.When touching pushing section 434 to different position, Ke Yirang
Handle forward or inversely promotes nut, so that screwing or unscrewing for nut, can realize that combined type joins in narrow space
Extension bar couples to the locking between workpiece.Such as it is used for the multiple casings for fixing display screen.Because bidirectional modulation handle needs to keep
In the state for forward engaging or inversely engaging, therefore, seamed edge 439 is provided with the side of hinge hole 431, on handle body 41 also

32；The front end of outer sleeve 31, which is provided with, is used for the rollback groove 311 of the accommodating steel ball 23 discharged；The periphery of fixed lid 22 be provided with to
The lug boss 221 of preceding extension；The rear end of outer sleeve 31 is provided with the lock groove 312 and opening groove 313 corresponding with lug boss 221；
When outer sleeve 31 is rotated to 313 respective protrusions portion 221 of opening groove, when its rear end slides into rollback groove 311 corresponding to steel ball hole
210, inner sleeve 32 is in the presence of elastic force, in front position, blocks steel ball 23 and is moved to center, and steel ball 23 is further kept off
Firmly the forward end of outer sleeve 31 is moved, and is maintained at the position of rear end, i.e. inner sleeve 32 and is located at foremost, blocks steel ball 23 not to inner side
Mobile, when being not inserted into connection bar body 10, inner sleeve 32 is always held at the position of front end, and outer sleeve 31 is always held at rear end
Position.When the front end of connection bar body 10 from fixed seat pipe 20 is inserted into jack portion 21, the compression of inner sleeve 32 is mobile to the back-end,
Steel ball 23 is outwards extruded to rollback groove 311；When the buckling groove 11 for coupling bar body 10 corresponds to the position in steel ball hole 210, overcoat
Cylinder 31 is slided by elastic force forward end, and the contact point of steel ball 23 and outer sleeve 31 is slided to the endoporus of outer sleeve 31 by rollback groove 311
Wall 319, inwardly compression is placed in buckling groove 11 stress of steel ball 23, can so realize auto lock, in order to safer, is prevented
Only outer sleeve is moved by the effect of improper external force, can rotate outer sleeve 31 to lock groove 312 corresponding to convex
Play portion 221.In order to easy to operate, the present embodiment is designed as being rotated by 90 °.Wherein, the depth of lock groove is far smaller than opening groove
Depth, when lock groove corresponds to lug boss, outer sleeve can only axial movable several millimeters of stroke.
Also include the outer spring 222 (acting on outer sleeve 31) for being sheathed on the fixed periphery of lid 22, fixed lid 22 is provided with endoporus
