The invention discloses a circuit breaker and a buckle assembly thereof. The buckle assembly comprises a buckle and protrusions. The two protrusions are distributed on a first shell body and a second shell body of a circuit breaker shell. The buckle comprises a frame and elastic clamping strips with clamping heads, and the frame is arranged on the circuit breaker shell in a sliding mode. Each protrusion comprises a sliding surface and clamping surfaces used for being connected with the corresponding elastic clamping strip in a clamping mode, wherein the clamping surfaces comprise the first clamping surface and the second clamping surface, the inclination angle of the first clamping surface relative to the horizontal plane is larger than the inclination angle of the second clamping surface relative to the horizontal plane, and the inclination direction of the sliding surface is opposite to the inclination direction of the clamping surfaces. The buckle is connected with the clamping surfaces in a clamping mode; in the assembling process, the clamping heads slide along the clamping surfaces, elastic force of the buckle is generated by abutting deformation of the clamping heads and the clamping surfaces, and the buckle can generate clamping force large enough as long as moving by a small distance when installed on a guide rail; in the disassembling process, the clamping heads are pulled away to the sliding surfaces, the buckle bounces off automatically, and barbs guarantee that the buckle does not bounce out of a body. Thus, disassembling is convenient, reliability is guaranteed, and labor intensity is reduced.

The invention discloses a floating block structure and a mold. The floating block structure comprises a floating block, pressing blocks and lifting pin assemblies; the floating block is movably arranged on a lower mold and provided with floating block limiting parts, the floating block limiting parts are matched with floating block limiting matching parts on the pressing blocks, and upward displacement of the floating block is restricted; the lifting pin assemblies comprise lifting pins and elastic pieces, the lifting pins are arranged on the lower part of the floating block, and the lifting pins are connected with the elastic pieces and can move up and down to drive the floating block to move up and down; the lifting pins are provided with lifting pin limiting parts, the lifting pin limiting parts are matched with lifting pin limiting matching parts on the lower mold, upward displacement of the lifting pins is restricted; and when the floating block moves upward to the withdrawing position, the lifting pin limiting parts abut against the lifting pin limiting matching parts. According to the floating block structure, the floating block is combined with the lifting pins, the strokemargins of the floating block are reserved, the floating block in the final state is not subjected to stress, the condition that pressing blocks cannot be subjected to stress and pop up can be ensured, and the mold and products are protected; meanwhile, limiting is carried out through the lifting pins, the withdrawing height can be adjusted by replacing the lifting pins; and the parts adopt mold inserting structures, the parts are convenient to assemble, disassemble and adjust.

The invention discloses a shifting fork press fitting resetting block pneumatic tool for an automotive combined switch. The shifting fork press fitting resetting block pneumatic tool for the automotive combined switch comprises a base plate, wherein a locating plate used for fixing a shifting fork is arranged on the base plate, an ejecting block, a first pneumatic cylinder, a pressure shaft and a second pneumatic cylinder are also arranged on the base plate, the ejecting block is used for ejecting the a resetting block, the first pneumatic cylinder is used for controlling the ejecting block to move, the pressure shaft is used for pressing the resetting block downward, and the second pneumatic cylinder is used for controlling the pressure shaft to move up and down. The shifting fork press fitting resetting block pneumatic tool for the automotive combined switch can be used for solving the problems that the traditional manual assembly is laboursome, efficiency is low and yield is low; meanwhile, the shifting fork press fitting resetting block pneumatic tool for the automotive combined switch is simple in structure and can be widely applied in the field of assembly of automotive switches.

The invention relates to a high-safety wear resistant brake cable. The high-safety wear resistant brake cable comprises an inner tube (1), a tubular layer (2), a first protection layer (3), a strengthened layer (4), a second protection layer (5) and a surface protection layer (6), wherein a steel wire consists of a carbon fiber core wire set and a resin layer; the carbon fiber core wire set is arranged in the resin layer; and the surface protection layer (6) is a wear resistant coating layer. The high-safety wear resistant brake cable resists the wear, and the outer layer thereof is not liable to be scraped or damaged by external force, so that the steel wire in the inner tube is not ejected out, and the driving safety is guaranteed.

The invention relates to a flat spiral spring which comprises a spring body, wherein the tail end of the utmost outer ring of the spring body is provided with an outer hook; the outer side of the utmost outer ring is provided with a fixing ring; and the outer hook is exposed to the fixing ring. Because the outer hook is exposed, being different form the traditional flat spiral spring, the outer hook can be directly installed in assembling without dismounting the fixing ring, therefore, the spring is very convenient to install, the spring outer ring can not be popped up to cause personal injury; and the spring is very convenient to maintain and replace.
