It is fixedly connected with the limited block 8 in rectangle, which slides and push against in limiting slot 7.Pass through limiting slot 7 and limited block 8
Setting effectively prevent interior bar 222 rotation, move in a straight line interior bar 222 can only along the axial direction of outer bar 221, facilitate behaviour
Sliding of the author to interior bar 222.
Referring to Fig. 2 and Fig. 3, outer bar 221 is close to pedestal 21(such as Fig. 2) radial direction on the inner wall of one end along outer bar 221 opens up
Having the mounting groove 9 of rectangular in cross-section, interior bar 222 is close to pedestal 21(such as Fig. 2) to offer section on the side wall of one end be equally in square
The specification size of the card slot 10 of shape, card slot 10 and mounting groove 9 is identical, and card slot 10 can face peace in sliding process for interior bar 222
Tankage 9.The fixture block 11 being engaged by clamping with card slot 10 is slidably connected in mounting groove 9, between fixture block 11 and the slot bottom of mounting groove 9
Spring 12 is installed, one end and the fixture block 11 of spring 12 are adhesively fixed, and the other end of spring 12 is Nian Jie with the slot bottom of mounting groove 9 solid
Fixed, fixture block 11 is provided with the second guide surface 13 cooperated with interior bar 222, second guide surface 13 setting far from one end of spring 12
In fixture block 11 towards the side of interior bar 222.The disassembly component for driving fixture block 11 to be detached from card slot 10 is additionally provided in outer bar 221
14.When interior bar 222 slides into 221 inside of outer bar, under the action of interior bar 222 and the second guide surface 13,11 compressed spring of fixture block
12 enter in mounting grooves 9, and when card slot 10 and when 9 face of mounting groove, spring 12 resets, and fixture block 11, which enters in card slot 10, to be completed pair
The fixation of 222 position of interior bar then drives fixture block 11 to be detached from card if interior bar 222 is skidded off outer bar 221 by disassembly component 14
Slot 10 can slide interior bar 222, then drive ball 4 to push against the outer wall of interior bar 222 to interior bar by turning set 51 again
222 positions are fixed, and operation is same convenient and efficient.
Disassembly component 14 includes the drawstring 141 being arranged in outer bar 221 and the pull ring 142 being mounted on 141 one end of drawstring,
One end of its medium pulling rope 141 and fixture block 11 are connected, and the other end of drawstring 141 is pierced by outer bar 221, and pull ring 142 is mounted on drawstring 141
It is pierced by one end of outer bar 221.Drawstring 141 can be more easily pulled by pull ring 142, to drive fixture block 11 and card slot 10
It is detached from, makes the cancellation for being clamped relationship between outer bar 221 and interior bar 222, and then slide interior bar 222 with respect to outer bar 221
It is dynamic.
The implementation principle of the present embodiment are as follows: when being measured using theodolite, by pulling drawstring 141 to drive fixture block 11
It is detached from, the position of interior bar 222 can be slided from card slot 10, the first guide surface is then made by rotary motion set 51 again
52 driving balls 4 are pushed against on the periphery wall of interior bar 222, are finally reached the adjustment to 22 entire length of support rod.Work as theodolite
When detection finishes, by reversely rotating turning set 51, interior bar 222 can be slid into inside outer bar 221, then pass through fixture block 11 and card
The position of interior bar 222 is fixed in slot 10 and ball 4, is finally reached and shortens to the whole length of support rod 22, reaches
Easy to carry and storage purpose effect.
The embodiment of present embodiment is the preferred embodiment of the utility model, and not limitation is originally practical new according to this
The protection scope of type, therefore: the equivalence changes that all structures, shape, principle according to the utility model are done should all be covered by practical
Within novel protection scope.
