Embodiment 3, is connected by an engaging retaining mechanism between front extension bar with rear extension bar；Engaging retaining mechanism includes being located at
Front holding section on front extension bar and the rear holding section being located on rear extension bar, two holding sections are suitable, rear extension bar is additionally provided with by
The locking member that the locking of said two holding section is spacing.Front holding section includes from determining that front extension bar rear end end face extends axially outwardly
Position post, it is pullover that rear extension bar front end is provided with the extension bar suitable with described locating dowel, and locating dowel includes the first cylinder being located at front portion,
Be located at second cylinder at rear portion, the second cylinder insert after in the hole, location that is provided with, extension bar front end；Forward and backward extension bar is fixed by axis hole
Position, the rotation centerline in locating dowel and hole, location overlaps, and can ensure extension bar stability very well.The first master that locating dowel is anterior
It is two that the surface of revolution of body is provided with the quantity of projection, is symmetrically distributed in locating dowel, and projection is sector；Pullover the returning of extension bar
Turning face and be provided with a pair draw-in groove, this draw-in groove is " L " type of outer narrow inner width, and suitable with projection, and this draw-in groove is through pullover to extension bar
Front end, and the pullover front end surface of extension bar is open type, projection can from " L " type draw-in groove of narrow inner width the entering of opening,
Thus projection and card slot fit, limit front extension bar and rear extension bar at axial direction.The projection of sector structure and card slot fit, permissible
Reduce stress to concentrate, be better protected from before and after two extension bar and diametrically displacement occurs, make extension bar more stable reliably；Front extension bar with after
Extension bar is by the connected mode of projection with draw-in groove, and structure is ingenious, convenient and fast connection, reliable and stable, adapts to various sizes of connecing
Bar connects.It is provided with a pair axial slide corresponding with draw-in groove at the outer wall that extension bar is pullover, and, axial slide and described lock
Tight part is suitable；Locking member includes a stop block, and stop block includes the annulus suitable with rear extension bar, and annulus is enclosed within rear extension bar
On, also including justifying by oneself two push stopping part that ring forward extends out, push stopping part inserts axial slide, limits the projection in draw-in groove
Position, when preventing extension bar from rotating, projection skids off " L " type draw-in groove, so that can transmit stable torsion between front extension bar and rear extension bar
Square active force.Above-mentioned locking member also includes the elastic spacing assembly being sheathed on rear extension bar, and elastic spacing assembly includes being positioned at
Front back-up ring on front side of stop block, it is positioned at the spring mechanism on rear side of stop block and rear back-up ring.Rear extension bar is provided with cannelure, coiling machine
Structure includes the extrusion spring being positioned on rear side of stop block and is positioned at the jump ring at cannelure, and rear back-up ring is arranged on jump ring and extrusion spring
Between be provided with rear back-up ring.Squeezing action dorsad is provided to rear ring washer and extrusion spring by the jump ring being fixed on cannelure
Power, thus stop block is pressed in axial slide, lock two extension bars, it is also possible to quickly stop block is exited axle by front back-up ring
To chute, such that it is able to the front extension bar of sharp separation and rear extension bar, simple in construction, easy to operate, can greatly reduce staff's
Working time, improve work efficiency.In using, after first the locating dowel of front extension bar rear end being inserted, the extension bar on extension bar front end is pullover
Hole, location in, the opening from extension bar is pullover of the projection in locating dowel enters beloid " L " draw-in groove, connects before then rotating
Bar make projection and extension bar pullover on card slot fit, thus it is moving axially relative to limit forward and backward two extension bars.Then, successively by front
Back-up ring, stop block, extrusion spring, rear back-up ring and jump ring are come in from the other end set of rear extension bar, and the push stopping part on stop block is installed
On axial slide, projection is locked, make projection be fixed in draw-in groove, prevent front extension bar from relative turning occurring with rear extension bar
Dynamic, then transmit moment of torsion by the interaction between projection and draw-in groove；Jump ring is fixed in cannelure, by jump ring to rear shelves
Circle and extrusion spring extrude, so that the annulus of stop block is extruded by extrusion spring, the push stopping part making stop block is solid
Being scheduled in axial slide, the just connection of such two extension bars completes.Convenient and fast connection, simple in construction, low cost of manufacture, it is also possible to
According to actual needs, changing corresponding fit dimension and just can achieve the goal, the suitability is strong.During dismounting, it is only necessary to by past for front back-up ring
The direction of extrusion spring promotes, and extrusion spring is extruded under the effect of front back-up ring by the push stopping part of stop block, thus stop bit
The push stopping part of block skids off axial slide；At this moment can rotate front extension bar, then extract front extension bar from the opening part that extension bar is pullover, make
Projection exits draw-in groove, thus reaches the purpose that front extension bar separates with rear extension bar.Whole separation process is quick and convenient, simple to operate,
Substantially increase the work efficiency of operator.
