A surface of the working member is a polygonal prismatic outer surface including a plurality of circular cylindrical surfaces with different radii of curvature. A first connecting member and a second connecting member each extend from one end of the gripping member. The working member includes a first working member and a second working member. The first working member and the second working member are rotatably disposed over the connecting members. A stop mechanism is further included and configured to stop and release the working members. A sealing member is further included and disposed in a terminal portion of the first working member in order to prevent particulate matter from entering the inside of the working member.

Abstract: The present invention provides a laser ranging apparatus, including: a holder, a measuring part mounted to the holder, and a housing detachably connected to the holder, wherein the housing includes a first casing. The first casing is an integrally formed tubular structure detachably sleeved outside the holder. An advantage of the present invention is to provide a laser ranging apparatus for fixedly mounting a measuring component on a holder and installing a detachable casing on the outside of the holder so as to ensure that the position of the measuring component will not be moved during the disassembly and assembly of the casing and the ranging precision of the measuring part will not be affected. The casing is composed of several simple components, which can effectively reduce the process difficulty of the casing parts.

Abstract: A woodworking vise includes a profiled vise body (1), a first jaw (2) and a second jaw (2?). The first jaw (2) and the second jaw (2?) are disposed at both ends of the vise body along its longitudinal axis. The woodworking vise further includes at least one movable jaw (3). The at least one movable jaw (3) is slidably connected to a top surface of the profiled vise body. Between the movable jaw (3) and the top surface of the profiled vise body (1), a locking block (36) is disposed, and a bottom surface of the locking block (36) is slidably connected to the top surface of the profiled vise body (1). The movable jaw (3) includes a force applying means (34) and a camshaft (35). The camshaft (35) has at least one cam, and the force applying means (34) is connected to the camshaft (35).
