Abstract
A device for locking a machine or other movable device in place includes a supporting mechanism, two locking members, and a pushing mechanism. The pushing mechanism includes a sleeve, a driving member, a pushing member, a driven member, and locating members. At least one first guiding opening and at least one second guiding opening are defined on the sleeve. A first surface is defined on the driving member. A second surface is defined on the driven member. The driving member moves the driven member. The driven member rotates under interaction of the first and second surfaces. The driven member drives a free end of each locating member to move. The driven member drives the pushing member to lever free ends of the two locking members apart or moves the pushing member to bring the free ends of the two locking members closer.

A locking device used to lock a machine, the locking device comprising:
- a supporting mechanism;
- two locking members positioned on the supporting mechanism and distant from each other, and
- a pushing mechanism comprising:
- a sleeve positioned on the supporting mechanism and facing the two locking members, the sleeve comprising a sleeve body having a through hole, at least one first guiding opening and at least one second guiding opening;
- a driving member slidably and partially positioned in the through hole, and having a first surface on an end thereof;
- a pushing member placed on the two locking members and partially located between the two locking members, two pushing surfaces being defined on the pushing member and abutting against free ends of the two locking members respectively;
- a driven member rotatably positioned on the pushing member, a second surface being defined on an end surface of the driven member;
- and
- at least one locating member positioned on a peripheral wall of the driven member;
- wherein each of the at least one first guiding opening is defined on an end of the sleeve body and extends along an axial direction of the sleeve body, and each of the at least one second guiding opening is defined on the end of the sleeve body and communicates with the first guiding opening;
- and
- wherein the driving member moves the driven member, the driven member rotates at a predetermined angle under an interaction of the first surface and the second surface,
- the rotating driven member drives a free end of each of the at least one locating member to move from the first guiding opening into the second guiding opening or from the second guiding opening into the first guiding opening, the rotating driven member drives the pushing member to push free ends of the two locking members apart from each other or moves the pushing member far away from the two locking members to make the free ends of the two locking members close to each other.
