Abstract
A locking unit includes a frame to permit extension of a bolt. An upper portion of a bracket is pivoted to left and right side walls of the frame. A linking member has a rear part connected to the bracket, and a front part formed with an arcuate slot through which the bolt extends. A stationary clamping seat is fixed on the right side wall. A movable clamping member is mounted on the bolt. An operating lever is pivoted to a C-shaped connector about a first pivot, and is pivoted to the right side wall about a second pivot. When the bolt is moved to a locking position, the linking member counteracts the clamping force, which results in a pulling force that pulls the C-shaped connector in a direction toward the left side wall along a horizontal line defined by the bolt and the operating lever is prevented from being turned upwardly by the pulling force.
