Detailed Description

The utility model is further described below with reference to the accompanying drawings:

As shown in fig. 1-3, a ground well lid opening tool comprises a support wheel set 2, a lever 1 and a hanging piece 3, wherein the support wheel set 2 is provided with two supporting wheels 21 and an axle 22 with two ends provided with the two supporting wheels 21 respectively, the lever 1 is arranged on the axle 22 by taking the axle 22 as a fulcrum, the lever is provided with a power arm 11 and a resistance arm 12, the hanging piece 3 comprises a hook 32 and a hanging rod 31, the lower end of the hook 32 can hook the edge of a hanging hole 401 of a well lid 4, the upper end of the hook can hang the hanging rod 31, a hanging ring 33 which can be sleeved at the end part of the resistance arm 12 is arranged on the hanging rod 31, and the hanging ring 33 can rotate in any direction. During application, the lower ends of the two hooks 32 are respectively hooked on the edges of the two hanging holes 401 of the well lid 4, the upper ends of the two hanging rods 31 are hung, the hanging rings 33 are sleeved on the ends of the resistance arms 12, the rear ends of the power arms 11 are pressed by hands, the lever member 1 lifts the well lid 4 by taking the wheel shaft 22 as a pivot, and then the lifted well lid is moved away by dragging the supporting wheels 21, so that the purpose of opening the well lid 4 is achieved. The hanging ring 33 can rotate in any direction, and in fact, the lever member 1 can approach and be sleeved with the hanging ring 33 from any direction, so that the situation that a trolley formed by the lever member 1 and the support wheel pair 2 thereof cannot approach from the direction to perform manhole cover opening operation due to public facilities beside the manhole cover 4 or greening tree planting limitation is avoided. Compared with the prior art, the tool has the advantages of obvious and simple structure and very convenient operation.

As shown in fig. 6, further, the axle 22 includes a left half shaft 222, a right half shaft 223, and an axle sleeve 221, the left end of the left half shaft 222 and the right end of the right half shaft 223 are respectively mounted with the support wheels 21, the right end of the left half shaft 222 and the left end of the right half shaft 223 are respectively inserted into the axle sleeve 221 from the left end and the right end of the axle sleeve 221 and can be extended and positioned as required by the distance between the support wheels 21, and the lever member 1 is mounted on the axle sleeve 221. By means of the arrangement, the length of the wheel shaft 22 can be adjusted according to the size of the well cover 4, so that the end of the resistance arm 12 can be close to and hung on the hanging ring 33. In order to ensure that the wheel axle with the adjusted length does not extend and retract by itself, a fastening bolt 224 for fastening and positioning the left half axle 222 and the right half axle 223 is arranged on the axle sleeve 221.
