The two wall portions have two side surfaces. An inner thread portion is formed on the side surfaces along a direction of groove depth, the base body is laterally penetrated by the groove along a center of inner thread portion, a bottom portion connects the two wall portions and having a through hole formed therein and being coaxial to the inner thread portion; a drive bolt having a top rod and a screw rod being movably engaged with the inner thread portion, wherein the screw rod has a drive portion placed against to the top rod, the top rod is coaxially align to the through hole.

A bicycle tool mounted in a bicycle tube comprises a storage tube with an accommodating space, a ring protrusion protrudes radially outward from an outer end of the storage tube, an outer side of the storage tube is annularly provided with a tightening ring at a position close to the ring protrusion; and a repairing component having a base, one side of the base is provided with a tire sealer and another side thereof is fixed with a chain remover, when the repairing component is mounted on the storage tube, the chain remover is located on the outer side of the storage tube, when the bicycle tool is not in use, the bicycle tool can be accommodated in the tube of the bicycle, when the bicycle tool needs to be used, it can be directly pulled out and used without further adjustment to improve the convenience of use.

A multipurpose screwdriver and bit holder tool, comprising an outer housing defining a longitudinal axis having channels on the outer periphery for storage of one or more screw bits, ensuring secure retention and easy accessibility; an ergonomic anti-slip handle, ensuring a comfortable grip and convenient tool access with an attachment for difficult to access areas; a Slide-in and slide-out screw bit design in the channels in the outer periphery of the tool, allowing for quick tool interchange, wherein the screw-bits retained in place in the channels; and an wrench cap equipped with a magnetic slide-lock mechanism for secure screw bit storage. The tool further comprises hex Sockets, wingnut too, wire-bender tool, bubble leveler, spoke wrench, rulers, double sided screw bits in the internal housing. The screwdriver and bit holder tool can be used with an attachment having more tools.

A system for moving discrete articles comprising a system for fixing push rods to the chain comprising: two opposite sides (20) that support a conveyor plane (21); two chain holder guides (22), opposite and fixed to said sides (20); two chains (23) with links with protruding pins (24) sliding inside said two chain holder guides (22); push rods (25) fixed in a removable manner, transversally to said conveyor plane (21), to said pins (24) of said chain (23); characterized in that it comprises: blocks (30) having a central hole (31) designed to slide with friction over said push rods (25); said blocks (30) having a pair of holes (32), lateral to said central hole (31), designed to slide with friction over said pins (24).

A mini pump comprising a linear hand pump assembly and a valve core tool is disclosed. The linear hand pump assembly is configured to operate along a longitudinal pump axis and comprises a first end and a second end opposite the first end. The valve core tool is releasably coupled to the first end and has a central tool axis and a cavity centered on, and running parallel to, the central tool axis. The cavity passes through at least one of a top surface and a bottom surface of the tool and is shaped to mate with a valve core such that, with respect to rotation about the tool axis, the valve core is rotationally fixed to the tool. The pump axis and the tool axis are collinear when the tool is coupled to the assembly. The valve core tool and the pump assembly may be threadedly coupled.
