Bench vise is usually called vise, it is a very practical fixture that people use to clamp the workpiece. Bench vise is composed of pliers body, base, guide nut, screw and jaw body. The movable tong body slidingly cooperates with the guide rail of the fixed tong body through the guide rail. Bench vise is an essential tool for the pliers industry. The fitter uses it to assemble and disassemble saws, files and parts.  Bench vise prices  Pro'skit PD-374 mini working pliers table maintenance clamping pliers table vise clamping pliers: ￥ 70 Fashion universal 360 degree miniature fixed bench vise bench vise desktop clamping pliers blue 65mm: ￥ 69 Stanley (STANLEY) heavy-duty bench vice 6 inches 83-068-22: ￥ 1159 American Stanley Stanley bench vise light 4.5 inch small vice vise with anvil bench workshop tools 83-065: ￥ 299 Star (SATA) 70841 heavy square steel bench vice 4 inches: ￥ 645 Yizhili vise small miniature household precision flat-nose pliers heavy-duty multi-function table vise clamp mini workbench pliers black type 50 (jaw width 5 cm, supportable length 6.5 cm): ¥ 59.9 Note: The above prices are all from the Internet, for reference only.  Bench vise structure  The structure of the bench vise is composed of a vise body, a base, a guide nut, a lead screw, a jaw body, etc. The movable pliers body slidingly cooperates with the guide rails of the fixed pliers body through the guide rails. The screw is mounted on the movable pliers and can rotate, but cannot move axially, and cooperates with the screw nut installed in the fixed pliers body. When the handle is shaken to rotate the lead screw, the movable pliers body can be driven to move axially relative to the fixed pliers body, which plays a role of clamping or relaxing. The spring is fixed on the screw by means of the retaining ring and the cotter pin. Its function is to make the movable jaw body withdraw in time when the screw is loosened. The fixed jaw body and movable jaw body are equipped with steel jaws and fixed with screws. The working surface of the jaws is made with crossed netting, which makes it difficult for the workpiece to slide after clamping. The jaws are hardened by heat treatment and have good wear resistance. The fixed pliers body is installed on the swivel seat and can rotate around the axis of the swivel seat. When turning to the required direction, pull the clamping handle to tighten the clamping screw, which can be fixed under the action of the clamping disc The pliers are tight. There are three bolt holes on the swivel seat for fixing with the clamp table.  Type of vice  The specifications of the bench vise are expressed by the width of the jaws, which are 100mm, 125mm, 150mm, etc. Bench vices are general-purpose fixtures used to hold workpieces. There are two types of fixed and rotary type commonly used for fixing; according to the shape and function: there are two types with and without anvil. The above is the introduction of the price, structure and type of the bench vise. I hope that the above content will allow friends to have a better understanding of the bench vise. In fact, bench vices are also relatively common tools in life, and are generally used in the context of mechanical processing, so it is still necessary to understand them.
Corner cube Prism is also named retroreflector or trihedral prism.In the corner cube prism,three reflecting surfaces are perpendicular to each other,like the side wall of the cube.The input surface is perpendicular to the cube diagonal. Disregarding the anlge of the incidence,the output beam is parallel to the input one,but it is of opposite direction. Inset of the several corner prisms, for better matching,their extrance exit surface is often hexagonal.In case of this prism the phenomenon of full internal reflection occurs so it is not necessary,(however it is possible)to put mirror coating on the reflecting faces. Normally the reflection surfaces are AL reflection coating, and then covered with Cu and Black painting.
Pyramid prism/Corner Cube Retroreflector is always used to reflect the beam entering the prism face, regardless of its orientation to the beam. Corner cubes are widely used where precision alignment is difficult.
