A modular safety fence assembly is disclosed. The safety fence may include a fence panel assembly having a top rail, a bottom rail, and mesh panel. The safety fence panel assembly may also support post assembly capable of supporting the fence panel assembly and an anchor assembly which may anchor the support post assembly to the floor using one or more relatively shallow holes formed in the floor.

Disclosed herein is an adjustable shoring beam having a hook assembly configured to mate with E-track mating features. The adjustable shoring beam can be adjusted over a predetermined length range by adjusting the tube assembly and the rod assembly. In some embodiments, the extension length is fixed using a fixing clamp coupled to the tube assembly and the rod assembly. A connecting clamp and bracket may be used to couple a first adjustable shoring beam to a second adjustable shoring beam.

A clamping device includes a primary member with a central passage and a clamping member connected to the primary member. The clamping member includes an annular body that extends around the central passage between first and second ends. The device also includes an actuator mechanism with an actuator connected to the primary member at a pivot connection, and a pivot arm pivotably connected to the actuator at an eccentric connection spaced from the pivot connection. The actuator pivots between an unlocked position and a locked position, where the pivot arm engages the second end of the clamping member to move the first and second ends closer together. When moving the actuator mechanism from the unlocked to the locked position, the pivot arm travels ahead of the eccentric connection and/or toward the second end of the clamping member. Moving the actuator mechanism from the locked to the unlocked position causes the opposite movement.

A clamping device includes a primary member, a clamping member configured for selectively clamping the primary member to a mounting member, and an engagement mechanism configured to engage an exterior surface proximate to the front side of the primary member. The engagement mechanism may include an abutment member for abutting the surface, an input member for user manipulation, and a linkage between the input member and the abutment member to effect axial movement of the abutment member by the input member. An actuator mechanism for locking and unlocking the clamping member may also be included. The clamping device may be in the form of a barbell clamp in one configuration, which is configured for mounting on a mounting member in the form of a barbell and engaging a weight plate that defines the exterior surface.

Provided is a telescopic tube having a stabilizing structure, including: a first tube having an internal and external end, wherein at least three longitudinal stabilizing lines are protruded from an outer wall of the internal end, and at least one stabilizing line has a blocking surface disposed at one end thereof near the external end; and a second tube having an inner diameter larger than an outer diameter of the first tube and a diameter of an outer periphery of the stabilizing lines, and having an upper and lower end, wherein the upper end is provided with a blocking portion having an opening. The second tube is sleeved outside the first tube, the external end penetrates through the opening to expose outside the second tube, and the internal end remains therein. Therefore, the first tube can be stably slidable inside the second tube due to the stabilizing lines.

An adjustable and retractable rod apparatus includes an external pipe fitting, a multi-section rod unit and a positioning unit. The multi-section rod unit includes a first foldable rod and at least one second foldable rod, where the first and second foldable rods have the same outer diameter, and the positioning unit includes a linkage rope, a positioning component and a locking component, which are used to pull the external pipe fitting and the first foldable rod relative to each other. The linkage rope can be dragged, and the locking component and the positioning unit interlocked or separated. When the locking component and the positioning component are interlocked, the external pipe fitting can be connected to the multi-section rod unit in an unfolded state. When the locking component moves away from the positioning component, the first and second foldable rods of the multi-section rod unit are folded and in parallel relative to the external pipe fitting.

Sixpod stand for camera, speaker and the like is invented to place heavy camera, speaker or photo studio background support etc. Existing Tripod stand for camera, speaker and the like has only one column and three legs so that it cannot support heavy objects on the top of tripod stand. Namely, the current tripod stand is too weak to support such a heavy object. In addition, since the current tripod stand has only one extended rod, it cannot make its height longer than a sixpod stand. Especially the tripod is impossible to be used as a supporter for a photo studio background which need both strength and height. On the other hand, sixpod stand has two columns and six legs. Six legs support two columns and inside of two columns, there are three respective rods in two respective columns inner surface by outer surface so that the height of sixpod stand could be extended as high as the length of three rods inside of two columns. People could not only place a heavy object on the top of sixpod but also place such a heavy object on the position which is as high as the length of three rods inside of two columns.
