Handle 1 is connected by connecting tube 11 with one-level extension bar 2；2, two grades of extension bars 3 of one-level extension bar, three-level extension bar 4 structure it is identical, one-level
The head end of extension bar 2 is plugged with a connecting-rod cap 6, and the one end of connecting-rod cap 6 is fixedly connected with one-level extension bar 2, and the other end stretches out one
Level extension bar 2 is fixedly connected with the connecting tube 11 of handle 1；The end of connecting tube 11 is provided perpendicular to the axial direction of connecting tube 11 simultaneously
Through the U-shaped opening 7 of connecting tube 11, connecting-rod cap 6 is fastened in U-shaped opening 7 by shop bolt 8；
The end of one-level extension bar 2 is provided perpendicular to body of rod axial direction and through the U-shaped opening 7 of the body of rod, two grades of extension bars 3
Head end be plugged with a connecting-rod cap, in the U-shaped opening of the other end insertion one-level extension bar of connecting-rod cap and by alignment pin
Nail is fixed；The head end of three-level extension bar 4 is fixed in two grades of U-shaped openings of extension bar by the cooperation of connecting-rod cap and shop bolt；
The head end of finger pin 5 is fixed in the U-shaped opening of three-level extension bar 4 by the cooperation of finger pin joint 15 and shop bolt 8, finger pin 5
End is folded upward at 90 ° of formation bending sections.The other end of finger pin joint 15 is set on the head end termination of finger pin 5, is welded with finger pin
Connect fixation.
The new handle of this practicality, extension bar and finger pin total length are about in 1400mm.Extension bar be divided into one-level extension bar, two grades of extension bars and
Three-level extension bar, structure, size are identical (every section of effective length is 350mm), and quarter is printed on the outer wall of finger pin 5 and extension bar
Degree, it is therefore desirable to assembly connection is made a distinction according to different scales in assembling.Subsidiary connect in one-level by turning during combination
Adapter sleeve 9 on bar, is connected in the connecting tube 11 of handle, then adopts by that analogy and in a like fashion connects two grades
Bar, three-level extension bar and finger pin are connected with each other and complete assembling.The shop bolt 8 of extension bar head end and finger pin head end can in connection procedure
To limit phase each other, so as to ensure the mutual alignment after combination.Shop bolt 8 inserts the adjacent connection of another section simultaneously
Extension bar afterbody U-shaped opening 7 in mutually rotated for positioning, and between preventing extension bar；By solid between connecting-rod cap 6 and extension bar
Rationed marketing nail A is integrally formed the two.
The middle part of connecting-rod cap of the present invention 6 is provided with the projection of annular, the periphery set that connecting-rod cap 6 coordinates with U-shaped opening 7
It is provided with adapter sleeve 9；Adapter sleeve 9 is connected with the screw thread of connecting-rod cap 6.Processed by annular knurl outside adapter sleeve 9, inside is M10
Screw thread can be turned by hand and is connected with the M10 external screw threads of higher level's extension bar afterbody external diameter, so as to complete the group between two sections of extension bars
Close.The outer wall of extension bar and finger pin 5 is easy to directly read numerical value during detection through silk screen process scale.
In addition, being arranged with interstage sleeve 10 in the main body of finger pin 5, interstage sleeve 10 is fixedly connected on the master of finger pin 5 by fixing pin B
On body and close to adapter sleeve 9.The head end of extension bar and finger pin 5 is connected by fixing pin B with connecting-rod cap 6.With reference to Fig. 7,
The size of fixing pin B be 14mm, the main body that two passes finger pin 5 is connected with interstage sleeve 10, with reference to Fig. 6, fixing pin A then with
The inwall laminating of extension bar, does not pass the tube wall outside of extension bar, and its size is 12mm.
Finger pin of the invention 5 plays relatively crucial effect, it is necessary to ensure its intensity, using diameter in the product
Φ 6mm, material are that the wire rod bending of No. 20 steel is welded, and coloured through sanding and polishing rear oxidation or spraying is black, bending section
Length be 80mm.Further, since finger pin 5 generally solid setting, therefore finger pin joint 15 is then welded on finger pin, is removed from
The operation of processing perforate.
Handle 1 is since it is desired that bear relatively large moment of torsion, its connecting tube 11 and handle 12 are welded to connect, using material
It is No. 20 tubing of steel, the external diameter Φ 12mm of tubing, wall thickness 2mm carry out heat-tinting after sanding and polishing or spray as black.
Extension bar mainly selects the aluminium alloy (material 6061GB3190-96) of lightweight, the pressure at right angle 300N that can be born, the maximum that can be born
Moment of torsion 200N.M, surface is oxidized to be coloured or is sprayed into black.
Specific embodiment of the invention：Each extension bar and finger pin are combined first, then both hands are held handle 1 and made
Probe (bending section of finger pin) vertically downward, exerts oneself to be pressed into finger pin in optical cable burial soil until bottom, so close to trenched side-wall
Gently lifting after finger pin is rotated by 90 ° afterwards makes it catch on optical cable, can now be directly read on extension bar and soil layer flush
Scale value, so as to complete the measurement to pre-buried depth；Then lift after finger pin time is turn 90 degrees again, finger pin is taken from soil
Go out, complete a measurement process.Treat after the completion of all detections, be placed in kit bag after finger pin 5 and extension bar being disassembled.
Above-mentioned implementation method is not limitation of the present invention, and the present invention is also not limited to the example above, this technology neck
Change, remodeling, addition or replacement that the technical staff in domain is made in the range of technical scheme, also belong to this hair
Bright protection domain.
