In order to enable those skilled in the art to better understand the technical solutions of the present invention, with reference to the accompanying drawing to this reality
Be described in detail with novel, the description of this part be only it is exemplary and explanatory, should not be to the protection scope of the utility model
There is any restriction effect.
As shown in Figure 1-Figure 3, the specific structure of the utility model are as follows: it includes well lid 1, and 1 lower end of well lid is provided with
Support rod 2；The well lid 1 is articulated with 3 upper end of mounting base, and the mounting base 3 is embedded in underground, and 3 upper end of mounting base is set
It is equipped with counterbore 4,4 bottom of counterbore is provided with through-hole 5, and the through-hole 5 is connected to inspection shaft, and counterbore 4 and through-hole 5 are preferably coaxial
Setting, 4 bottom of counterbore are provided with fixing seat 6, and 6 side of fixing seat is arranged at intervals with telescoping tube 7, the telescoping tube 7
The casing nesting successively successively decreased by more diameters forms, and can stretch under external force, 7 end of telescoping tube and sliding seat
8 are fixedly connected, and the fixing seat 6 and sliding seat 8 are located at approximately the same plane, and the lower end surface and counterbore of fixing seat 6 and sliding seat 8
The contact of 4 bottoms, being horizontally disposed between the fixing seat 6 and sliding seat 8 has reset spring 9 and safety net 10, resets in order to prevent
The deformation of 9 vertical direction of spring, reset spring 9 can be sheathed on telescoping tube 7 by when use, while can be set to safety net 10 and be stretched
7 top of the draw, to utilize 7 support safety net 10 of telescoping tube, to improve the bearing capacity of safety net 10；4 bottom of counterbore in
6 two sides of fixing seat are vertically arranged fluted 11, are provided with pedestal 12 in the groove 11, under 11 bottom of groove and pedestal 12
Adjustable spring 13 is connected between end, 12 upper end of pedestal is provided with the magnet 14 for adsorbing sliding seat 8, the magnet 14
Position is adapted with support rod 2, and in order to ensure adjustable spring 13 and magnet 14 play a role, the support rod 2, pedestal 12 are using non-magnetic
Property material be made, the sliding seat 8 is made of magnetisable material.
