Concrete meaning in invention.
As shown in Figure 1 and Figure 2, the present invention provides a kind of telescopic rods, including outer tube 1 and the first interior bar 2；
First interior bar 2 is arranged in the outer tube 1；
Rotation seat 7 is fixedly installed on the outer wall of one end of the outer tube 1；
One end rotation of the rotation seat 7 far from the outer tube 1 is provided with retaining bar 5；
Multiple retaining protrusions 4 are fixedly installed on the outer wall of first interior bar 2；
One end of the retaining bar 5 can offset with the side of the retaining protrusion 4, for preventing out of the outer tube 1
First interior bar 2 of extraction returns in the outer tube 1.
In the present embodiment, when in use, the first interior bar 2 is drawn upwardly out out of outer tube 1, then rotation seat will be rotatably arranged on
The upper end of retaining bar 5 on 7 offsets with the retaining protrusion 4 on 2 outer wall of the first interior bar, and then prevents the whereabouts of the first interior bar 2, into
One step avoids the first interior bar 2 and falls back in outer tube 1.
When needing the first interior bar 2 being recovered in outer tube 1, the first interior bar 2 is slightly carried upwards, by retaining bar 5 and only
It moves back protrusion 4 to detach, rotates retaining bar 5 later, by retaining bar 5 far from the first interior bar 2, avoid contacting with the first interior bar 2, finally will
First interior bar 2 is recovered in outer tube 1.
The end that retaining bar 5 and retaining protrusion 4 offset can be tip as depicted in figs. 1 and 2, can also be circle
Or other shapes can prevent the first interior bar 2 from falling back in outer tube 1 as long as can offset with retaining protrusion 4.
Preferred embodiment is that the vertical section of the retaining protrusion 4 is right angled triangle；
One right-angle side of the right angled triangle is arranged on the outer wall of first interior bar 2, and another right-angle side is set
It sets in the retaining protrusion 4 close to the side of the outer tube 1.
The shape of retaining protrusion 4 is in the present embodiment the structure of the rectangular triangle of vertical section, and one right-angle side is solid
It is arranged on the outer wall of the first interior bar 2 calmly, another right-angle side is arranged in the lower section of retaining protrusion 4, can be with 5 phase of retaining bar
It supports.
It should be pointed out that in the present embodiment, the vertical section of retaining protrusion 4 is right angled triangle, but its not only office
It is limited to a kind of this shape, can also be the other shapes such as obtuse triangle, diamond shape, as long as raised 4 Hes of retaining can be passed through
The cooperation of retaining bar 5 prevents the first interior bar 2 to be recovered in outer tube 1.
Preferred embodiment is to be provided with elastic force locking device on the retaining bar 5, for making the retaining bar 5 begin
There is the power to offset with the retaining protrusion 4 eventually.
In the present embodiment, in order to give retaining bar 5 one power to offset always with retaining protrusion 4, it is arranged on retaining bar 5
Elastic force locking device.
After elastic force locking device, when the first interior bar 2 is extracted out, can directly it extract out without again to retaining bar
5 are controlled, and are simplified operation, have been saved time cost, and the efficiency of operation is improved.
When in use, it is only necessary to directly extract the first interior bar 2 out of outer tube 1 out.And retaining bar 5 is locked in elastic force and is filled
It under the action of setting, can remain that the lower section with retaining protrusion 4 offsets, and then ensure that the first interior bar 2 will not fall back to outer tube 1
It is interior.
When withdrawing the first interior bar 2, it is only necessary to which negative direction rotation retaining bar 5 can make the first interior bar 2 fall back to outer tube 1
It is interior.
Preferred embodiment is that the elastic force locking device is the compression spring 8 being arranged in 5 other end of retaining bar；
One end of the compression spring 8 offsets with the retaining bar 5, and the outer wall of the other end and the outer tube 1 offsets；
