Problems solved by technology

[0003] Due to the limitation of equipment space, some bolts cannot be disassembled directly with an air gun or an extension rod, and a universal joint is required. At present, the universal joints on the market are generally connected by pin shafts. Stable, the universal joint is easily damaged due to the excessive torque during the start-up process of the air gun

Abstract

The invention discloses a stable transmission bolt disassembling universal joint, and mainly relates to the field of hardware tools. The stable transmission bolt disassembling universal joint is applied to bolt disassembling, and the problems that a universal joint is unstable in transmission and prone to damage in the prior art are solved. The universal joint is characterized in that the universal joint comprises a housing, a transmission sub-head, a bearing, transmission rods and a transmission main head; the transmission sub-head and the transmission main head are fixedly arranged inside the housing through the bearing; the transmission sub-head and the transmission main head are connected by the transmission rods; the transmission rods include the first transmission rod and the secondtransmission rod; the first transmission rod and the second transmission rod are hinged; and the transmission main head drives the transmission sub-head to rotate through the transmission rods. According to the stable transmission bolt disassembling universal joint, the bendable transmission rods are adopted to replace pin connection; compared with the transmission mode of a traditional universaljoint, the stable transmission bolt disassembling universal joint is more stable in transmission, and the universal joint is not prone to damage.

Description

technical field [0001] The invention relates to the field of hardware tools, in particular to a bolt removal universal joint with stable transmission. Background technique [0002] A bolt, a mechanical part, is a cylindrical threaded fastener with a nut. A type of fastener consisting of a head and a screw (a cylinder with external threads), which needs to be matched with a nut to fasten two parts with through holes. This connection form is called bolt connection. If the nut is unscrewed from the bolt, the two parts can be separated, so the bolt connection is a detachable connection. [0003] Due to the limitation of equipment space, some bolts cannot be disassembled directly with an air gun or an extension rod, and a universal joint is required. At present, the universal joints on the market are generally connected by pin shafts. Stable, the universal joint is easily damaged due to the excessive torque during the start-up process of the air gun. Contents of the inventio...
