Device.
The present invention adopts the technical scheme that to solve above-mentioned technical problem：
A kind of laborsaving well lid opening and closing device, including extendable lever, herringbone support and lifting rope, its main feature is that：The herringbone branch
Frame is flexibly connected with extendable lever, and the lifting rope is formed for two ropes, which is fixed in described stretch after merging
One end of contracting lever, the lower end of two ropes are respectively arranged with suspension hook, in use, in the hole for hoist of suspension hook insertion well lid, are stretching
The other end force of contracting lever.
The suspension hook has contact with for bushing type, including casing, sunpender, resilient cross-bar, described sleeve pipe upper end are provided with closing in,
The closing in internal diameter is slightly larger than the outside diameter of the sunpender, and sleeve outer wall middle and lower part is provided with slot hole, and the lower end of casing opens；It is described to hang
Chuck, the sunpender threading are provided with bar, the chuck is located in the closing in of sleeve upper end；The resilient cross-bar is hinged
In sunpender lower part, and two are arranged symmetrically, and are pierced by out of described slot hole, are set in the articulated mounting between resilient cross-bar and sunpender
There is spring, usually, resilient cross-bar is in unfolded state, and when sunpender is moved downward relative to casing, the resilient cross-bar is in institute
Under the barrier effect for stating the lower edge of slot hole, it is upwards collected through.
The suspension hook is L-shaped, including montant and cross bar, the upper surface of the cross bar are provided with anti-slop serrations.
Compared with prior art, the present invention have the advantages that：
Due to present invention employs extendable lever and herringbone support, well lid is opened and closed by rope skipping and suspension hook, Labor-saving safety, and
Too many space is not take up, easy to carry, work efficiency is high.

Embodiment
As shown in Figure 1, a kind of laborsaving well lid opening and closing device, including extendable lever 2, herringbone support 3 and lifting rope 1, its feature
It is：The herringbone support 3 is flexibly connected with extendable lever 2, and the lifting rope 1 is formed for two ropes, which closes
One end of the extendable lever 2 is fixed in after and, the lower end of two ropes is respectively arranged with suspension hook 5, in use, suspension hook 5 is inserted into
In the hole for hoist 4-1 of well lid 4, exert a force in the other end of extendable lever 2.
As shown in Figures 2 and 3, the suspension hook 5 has contact with for bushing type, including casing 5-4, sunpender 5-1, resilient cross-bar 5-
2, described sleeve pipe 5-4 upper end are provided with closing in 5-6, which is slightly larger than the outside diameter of the sunpender 5-1, in sleeve outer wall under
Portion is provided with slot hole 5-3, and the lower end of casing 5-4 opens；Chuck 5-5 is provided with the sunpender 5-1, the sunpender 5-1 is penetrated
Casing 5-4, the chuck 5-5 are located in the closing in 5-6 of sleeve upper end；The resilient cross-bar 5-2 is hinged on sunpender 5-1 lower parts,
And two are arranged symmetrically, it is pierced by out of described slot hole 5-3, is provided with the articulated mounting between resilient cross-bar 5-2 and sunpender 5-1
Spring, usually, resilient cross-bar 5-2 are in unfolded state, and when sunpender 5-1 is moved downward relative to casing 5-4, the elasticity is horizontal
Bar 5-2 is upwards collected through under the barrier effect of the lower edge of the slot hole 5-3.
As shown in figure 4, the suspension hook 5 is L-shaped, including the upper surface of montant 5-7 and cross bar 5-9, the cross bar 5-9 are set
