Specific implementation mode
Below in conjunction with the accompanying drawings, a specific implementation mode of the utility model is described in detail, it is to be understood that this
The protection domain of utility model is not restricted by specific implementation.
As shown in Figures 1 to 7, a kind of rail measuring instrument protective device that the utility model embodiment provides, including clip,
Sliding block 30, the locating rod 31 being connected on sliding block 30, the positioning sleeve 32 for being set in connecting rod and protective cover 33, clip are used
In protective device to be mounted on the column 10 of measure field, locating rod 31 is cuboid, as shown in fig. 6, its length extension side
Four upward seamed edges are circular arc chamfering, and protective cover 33 has a cylindrical positioning chamber, and opposite both sides are bow in positioning chamber
Shape, the distance between two bowed strings are less than the maximum distance between two circular arc chamferings on 31 diagonal line of locating rod, fixed
Position set 32 can limit under the action of arch in specific position, and when needing to convert position, manpower rotational positioning set 32 is fixed
Crimp is generated between the arch and the circular arc chamfering of locating rod 31 of position set 32, when arch crosses the position of circular arc chamfering,
Positioning sleeve 32 restores original form and is located in another specific position again, to realize the positioning conversion of different location, card
Hoop includes the first noumenon 20 and the second ontology 21, and the side of the first noumenon 20 and the side of the second ontology 21 are hinged, first
