A tool holster includes a connector of a clip is provided for detachably securing a tool to a leg harness. A fastener stud is attachable to the tool. The holder rotatably receives the fastener stud for movements between a first angular orientation that permits the fastener stud to be selectively received and removed from the holder and a second angular orientation that prevents the fastener stud received within the holder from being separated or removed from the holder. A support member is attached to the fastener stud for sharing common rotational movements therewith and connectable to a tool to be supported. The support member is oriented to move the fastener stud to the second angular orientation only when the tool is freely suspended on the holder under the action of gravity regardless of the position or orientation of the user's leg.

A support truss for a messaging sign comprising an elevated box truss which extends over a roadway and which has its opposite ends secured to upstanding supports. The box truss is comprised of a plurality of box truss sections secured to one another in an end-to-end relationship with at least one of the box truss sections adapted to have one or more messaging signs mounted therein. The messaging signs are horizontally slidably adjustably mounted on the box truss section so that the box truss section can accommodate signs having various thicknesses. The box truss in which the messaging sign is mounted is designed so that the face of the sign is unobstructed to permit motorists to readily observe the messages on the sign. A walkway is provided within the truss rearwardly of the messaging sign.

The invention discloses a hydraulic cylinder with a locking device. The hydraulic cylinder comprises a piston, a piston rod and the locking device, wherein the locking device is provided with a wedge-shaped hole and a wedge-shaped component, and when the locking device is in a locking state, the wedge-shaped component is clamped between the piston rod and the wedge-shaped hole and the large end tends to move towards the small end. When the hydraulic cylinder needs to be locked, the wedge-shaped component is arranged in a clearance between the wedge-shaped hole and the piston rod to clamp the piston rod, so that the piston rod is locked in a designated position. Hydraulic oil in a rod-free cavity and the locking device of the hydraulic cylinder work commonly, so that the piston rod can be locked in the designated position, the uncontrolled contraction of the piston rod can be avoided, and the working reliability of the hydraulic cylinder can be improved. The invention also discloses a hydraulic system with the hydraulic cylinder and an engineering machine with the hydraulic system.
