【Embodiment】
Embodiment：
Refer to Fig. 1-Fig. 2, the present embodiment for ease of carrying lever type manhole cover opening device 100, it include axletree 1,
Wheel 2 positioned at the two ends of axletree 1, the fixation block set 3 for being set in the appearance of axletree 1, perpendicular to fixed block set 3 and it is fixedly installed on it
On bearing bar 4 and be hinged with the one end of bearing bar 4 and the telescopic force application rod 5 of length.
It is hinged on bearing bar 4 relative to the fixed other end of block set 3 and is provided with carrying suspension hook 6, two is provided with carrying suspension hook 6
Fastening hook 7 to hooking four Angle Positions of well lid, two fastening hooks 7 of a centering are connected by rope or chain.
Be provided with bearing bar 4 close to one end of fixed block set 3 support well lid surface support bar 8, sling in well lid
During, support the surface that bar 8 supports well lid so that will not be collided close to well lid with wheel 2, and not interfere with wheel
2 rolling walking；And by supporting bar 8 by well lid surface inclination certain angle so that rope or chain in carrying suspension hook 6 are not
