The invention provides a bicycle wheel. A locating body, an inner gear ring, a driving gear and the like are added to a hub of a driving wheel of a bicycle, and great difference exists between the driving method of the bicycle and an existing transmission method. According to the existing driving method, a chain only drives a fly wheel and the wheels to rotate to enable the bicycle to advance, after the parts are arranged, except that the chain drives a chain wheel namely the fly wheel and the wheels rotate to enable the bicycle to advance, forward inclining force is produced by the wheels, and a labor-saving effect is achieved.

The invention discloses a clamp, the existing clamp is difficult to meet the using requirements of leading a guide rod to realize big-step feeding in neutral gear and obtaining greater clamping force during clamping, a fixed clamp body of the clamp comprises a grab handle which extends to the end which is not fixed with a clamping head and a fixed supporting part, a force application handle is arranged by corresponding to the grab handle, and a force application part for pushing a force application clamping piece, a first fulcrum part which is farther away from the force application part and a second fulcrum part which is nearer to the force application part are arranged on the force application handle, wherein an elastic element is connected between the first fulcrum part and the fixed clamp body, and the second fulcrum part is arranged by corresponding to the fixed supporting part. The clamp can lead the force application handle to act by taking the first fulcrum part as the fulcrumin the neutral gear, thereby leading the force application part of the force application handle to obtain a greater amount of feeding and realizing fast feeding; and the clamp can further lead the force application handle to act by taking the second fulcrum part as the fulcrum during clamping, thereby leading the force application part of the force application handle to obtain the greater clamping force.

The edge structure for perforator includes one main body; one first piercing end on one side of the bottom end of the main body for piercing some body; one second piercing end on the other side of the bottom end of the main body for piercing some body for further piercing; and one notched cutting surface between the two piercing ends for cutting the pierced body. The cut bits is exhausted via the gap formed between the two piercing ends in different heights.

The invention relates to a cutting ruler, in particular to a cutting ruler for assisting tailoring and aims at achieving the technical effect of providing the cutting ruler for assisting tailoring with diversified assisting functions. The cutting ruler for assisting tailoring comprises a scale plate, a connecting rod, a pressing handle, an air bag, a first spring, a circular plate, a first outer scale, an inner scale, a sliding block, sliding rails, a blade and a movable plate; the circular plate is arranged on the right side of the scale plate, the air bag is arranged on the top of the circular plate, the first spring is arranged on the top of the circular plate, the pressing handle is arranged at the upper end of the first spring and located in the air bag, the connecting rod is connected to the left side of the bottom of the pressing handle in a hinged mode, the sliding rails are arranged on the front side and the rear side of the top of the scale plate respectively, and the sliding block is connected between the sliding rails. By the adoption of the first outer scale and a second outer scale, the length of the front side and the length of the rear side of cloth can be measured at the same time, size measuring time is saved, the scale plate does not need to be turned over, and the effort saving effect is achieved.

The invention discloses a large-air-volume inflator. The large-air-volume inflator comprises an outer pipe, a middle pipe and an inner pipe. The front end of the outer pipe is fixedly connected with a front cover in a sealed manner. The front end of the inner pipe is fixedly connected with the front cover in a sealed manner. An air outlet assembly is arranged on the front cover. The rear end of the middle pipe extends out of the rear end of the outer pipe and is fixedly connected with a rear cover in a sealed manner. A first one-way seal piston assembly is fixedly arranged at the front end of the middle pipe. A second one-way seal piston assembly is fixedly arranged at the lower end of the inner pipe. The large-air-volume inflator is characterized in that a first ventilation opening is formed in the side wall of the front end of the middle pipe; a second ventilation opening is formed in the side wall of the front end of the inner pipe; a first one-way air inlet valve which can only introduce air into the inner pipe is arranged in the second one-way seal piston assembly; and a second one-way air inlet valve which can only introduce air into the inner pipe or the air outlet assembly is arranged at the position of the second ventilation opening. The large-air-volume inflator has the beneficial effects that compared with a traditional single-cylinder inflator, the single-time inflation volume of the large-air-volume inflator is large, the number of tire inflation times can be halved, the tire inflation time is greatly saved, the inflation efficiency is improved, and meanwhile the effect of saving labor is achieved.

The invention discloses a stapler staple removing device. The stapler staple removing device comprises a base (1), a staple removing knife (8) which can be arranged on the base (1) in a sliding mannerin the vertical direction and a pulling force supplying mechanism which can drive the staple removing knife (8) to slide in the vertical direction, wherein the staple removing knife (8) at least comprises a sliding part (15) which is vertically arranged and a staple clamping part which is arranged at the lower end of the sliding part (15) and extends in the horizontal direction; and a groove (14)which is perpendicular to the extending direction of the staple clamping part is formed in the upper surface of the staple clamping part. Through the adoption of the stapler staple removing device disclosed by the invention, the effects that staples can be drawn off in a labor-saving manner, a certain restricting effect on the staples can be achieved, and the safety in the operation process is improved are realized.

The orthopedic clinical hip joint reduction fixator comprises a frame plate, a supporting plate is fixed to one side of the front end of the frame plate through a bolt, a first sleeve rod is fixed to the top of the supporting plate through a bolt, a first groove is formed in the top of the first sleeve rod, and a first spring is fixed to the inner wall of the bottom of the first groove through a bolt; a first inner rod is fixed to the top of the first spring through a bolt, a holding rod is fixed to the inner side of the first inner rod through a bolt and sleeved with a rubber sleeve, the shifting mechanism is connected with a disc, the top of the disc is rotationally connected with a second sleeve rod through a bearing, a second groove is formed in the top of the second sleeve rod, and a second spring is fixed to the inner wall of the bottom of the second groove through a bolt. Second inner rods are fixed to the tops of the second springs through bolts, and adjusting plates are fixed to the tops of the second inner rods through bolts. The hip joint is subjected to reduction action, and meanwhile, the body of a patient is pressed down and fixed, so that the reduction process can be operated by a single person.
