Embodiment

The utility model is described in further detail below：

With reference to Fig. 1, Fig. 2, Fig. 3, a kind of removable Well cover unlatching tool, including handle 1, force rod 2, drag strut 3, hook 4th, universal wheel 5, rotating device 6.Handle 1 is arranged on the left end of force rod 2, and end is hinged with drag strut 3 among force rod 2 or rearward, The bottom of drag strut 3 is provided with hook 4, can be used to pick up well lid, while the right-hand member of force rod 2 and rotating device 6 are be hinged, rotating device 6 Bottom is connected with universal wheel 5；4 and the hole clamping on well lid will be linked up with during use, and universal wheel 5 is supported into ground as branch Point, by applying power straight up to handle 1, utilize lever principle, in that context it may be convenient to by well lid pull-up, while pass through rotation Device 6 can flexibly move well lid position, can also arbitrarily be moved by universal wheel 5 when idle, effectively reduce worker's Labor intensity.

Universal wheel 5 is made up of rotating seat 5-1, wheel support 5-2, nut 5-3, bolt 5-4, wheel 5-5；Rotating seat 5-1 turns Dynamic to coordinate on wheel support 5-2, wheel support 5-2 lower ends are connected with wheel 5-5 by bolt 5-4, and bolt 5-4 passes through nut 5-3 Locking coordinates, while wheel 5-5 can rotate around bolt 5-4.

Rotating device 6 is by pin 6-1, support frame 6-2, nut 6-3, groove 6-4, hair clip pin 6-5, upper bed-plate 6-6, ball 6-7, retainer 6-8, lower bottom base 6-9 compositions；Upper bed-plate 6-6 is coordinated by ball 6-7 and lower bottom base 6-9, lower bottom base 6-9 and spiral shell Cap 6-3 screws cooperation, and nut 6-3 outer ends process fluted 6-4, easily can tighten and screw out during use, while ball 6-7 leads to Retainer 6-8 to be crossed to fix, pin 6-1 one end is provided with through hole, is connected with hair clip pin 6-5, and then fixes pin 6-1, under Base 6-9 is evenly arranged 3 support frame 6-2, fixed support lower bottom base 6-9 along axis.
