[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] like Figure 1-2 As shown, the utility model provides a technical solution: a multifunctional puller, which is arranged on the ground, comprising: a base structure and a lever structure, the base structure is arranged on the ground and is used to support the lever structure, and the lever structure is arranged on the base structure and is used to lift the manhole cover.

[0025] like Figure 3-4As shown, the base structure includes a base unit arranged on the ground, and a bearing unit arranged on the base unit, and the base structure is used to bear the remaining structures. The base unit includes a base 1 arranged on the ground, the base 1 is made of angle steel and has a diameter of ∠63×6, the length of the base 1 is 300mm, and the height is 63mm, and a column 2 arranged on the base 1, the material of the column 2 is the same as that of the base 1 and has a diameter of ∠50×5, the number of the columns 2 is at least two, and the two columns 2 are arranged in a mirror-image manner at the center of the base 1, the inner side spacing of the two columns 2 is 30mm, the height of the column 2 is 250mm, and the width is 50mm. The two columns 2 are provided with connecting holes, the size of the connecting holes is consistent with the size of the horizontal axis 3, and are used to connect the horizontal axis 3 is inserted into the connecting hole to stabilize the connection of the horizontal axis 3. The two columns 2 can stably support the bearing unit. The base unit is used to fix the bearing unit.
