And when the angle needs to be adjusted, a second bolt can be loosened, the angle of the clamping assembly can be conveniently adjusted, and the diversity of the whole device is improved.

The utility model provides an auxiliary tool for quickly opening a blind plate, which comprises a mounting ring detachably mounted at the front end of a barrel flange; the rotating ring is coaxially and rotatably mounted on the mounting ring, and the rotating ring is arranged on the peripheral wall of the cambered surface of the barrel flange in a sleeving manner; the puller bolt is elastically connected to the rotating ring and is in threaded fit with a bolt hole in the barrel flange; the impact rod is movably connected to the rotating ring and matched with a bolt hole in the barrel flange in an inserted mode. The quick-opening blind plate jackscrew hole is utilized, through mutual cooperation of the puller bolt and the impact rod, blocking and adhesion of the locking ring can be eliminated, the quick-opening blind plate difficult to open can be conveniently opened, the effect is good, and the service life of equipment is prolonged.

This application discloses a prism rod support structure, belonging to the field of measuring instruments. It includes: a fixed base, a first leg, a limiting member, and an elastic storage bag; the fixed base has a slot matching the diameter of the prism rod; one end of the first leg is rotatably connected to the fixed base, and the other end of the first leg contacts the ground; the limiting member is disposed on the end of the first leg rotatably connected to the fixed base; at least three first legs are disposed on the fixed base; the elastic storage bag is disposed on the fixed base; the elastic storage bag is used to store the first leg. The advantage is that the user can first remove the prism rod from the slot, align the first leg parallel to the axis of the fixed base, and then pull the storage bag towards the first leg to completely retract the leg, thereby limiting the angle at which the first leg opens relative to the fixed base, making the support structure easy to carry.

This invention relates to the field of mechanical transmission technology, and more particularly to an overrunning clutch. The overrunning clutch includes inner and outer rotating components and a transmission wedge. The transmission wedge has an outer contact surface and an inner contact surface. A spring mounting groove is provided at the end of the transmission wedge, in which a ring spring is installed. The ring spring radially supports the transmission wedge, causing the outer contact surface of each transmission wedge to contact the outer rotating component. The spring mating surface of the spring mounting groove that contacts the ring spring is inclined, so that in its natural state, the inner contact surface of the transmission wedge is separated from the inner rotating component. When the outer rotating component rotates forward, the transmission wedge rotates accordingly and, under the action of centrifugal force, overcomes the pressing action of the ring spring and wobbles around the outer rotating component until the inner contact surface contacts and weds into the inner rotating component. Thus, transmission between the inner and outer rotating components is achieved through the transmission wedge. This clutch avoids friction between the transmission wedge and the inner rotating component, extending the clutch's service life.
