Abstract
A leveling device for planar objects includes a first part having a circular end hole, a chamber, a flange, a handle, a contact portion, two blades and a bottom face. A second part includes a receiving hole, a first shoulder, two recesses, a slot, a mark, an axial hole and a second shoulder. The first and second parts are connected to each other. A movable member movably inserted into the first and second parts. The movable member includes a push potion, a middle section, a lower section and a room. An engaging member is securely inserted into the room and has a lower portion extending beyond the movable member. The engaging member is movable with the movable member. A resilient member is mounted to the lower section and biased between the middle section and the second shoulder.

A leveling device for planar objects, the planar objects being fixed to a flat surface, and the leveling device comprising:
- a first part having a circular end hole defined in a top thereof, a chamber defined through the top and a bottom of the first part, the chamber communicating with the end hole and having a flange extending inward from an inner periphery thereof, two hooks extending from a bottom face of the first part;
- a second part having a circular receiving hole defined in a top thereof, a lower portion of the first part received in the receiving hole, a first shoulder extending from an inner periphery of the receiving hole, the bottom face of the first part rested on the first shoulder, two recesses defined in the inner periphery of the receiving hole and the two hooks being hooked with the recesses so that the first and second parts are connected to each other, the second part having a slot defined radially therein, and an axial hole defined axially therein, the slot communicating with the chamber and the recesses, a mark formed on an outside of the second part, the axial hole communicating with the end hole, the slot located between the receiving hole and the axial hole, a second shoulder formed between the slot and the axial hole;
- a movable member having a push potion on an upper portion thereof and a lower section on a lower portion thereof, a middle section extending from the movable member and located between the push portion and the lower section, the push portion movably extending through the chamber and protruding beyond the top of the first part via the end hole, a shape of the middle section being shaped to be movable in the chamber of the first part, a room defined in a lower end of the lower section;
- an engaging member securely inserted into the room and having a lower portion extending beyond the lower end of the movable member, the lower portion located in the second part, two blades extending perpendicularly from the lower portion of the engaging member, the two blades exposed beyond the lower portion of the engaging member and extending along a direction identical to a direction that the mark extends, the engaging member having an upper portion which is fixed in the room, and
- a resilient member mounted to the lower section and biased between the middle section of the movable member and the second shoulder of the second part, the middle portion contacting an underside of the flange by the resilient member.
