Definitions
- the above invention relates to a tubular socket wrench with an articulated on the body of the socket wrench attached operating lever.
- Pipe wrenches of the type mentioned are usually for the assembly or disassembly of spark plugs used, which are used in internal combustion engines.
- socket wrenches are also used for screwing or used for unscrewing nuts or bolts that bad using a conventional one Spanner are reachable.
- Pipe sockets are known from the prior art where the key body is by forging an iron material is produced.
- the spherical body at the end of the Drive lever is usually made of solid material and using plastic forming processes to Example using a forging process, will be produced. It is also known to carry out there is no possibility of forging processes Ball body with flawless, smooth surface to manufacture.
- this object is achieved in that the Recess for receiving the coil spring from one Spring ring is limited, which in a circumferential groove on the Inner wall of the tubular body is inserted and between the upper end of the coil spring and the spherical body of the Actuating lever is arranged in a sliding shell has a peripheral edge at which the upper end of the spring is present.
- tubular socket wrench marked with 1 from one tubular body 2, which is plastic at its free end is deformed to create a polygonal recess 3.
- the pipe section 2 is with Provide recesses 4 and with the help of a Pin 5 becomes the ball piece 6 of an operating lever 7 articulated mounted.
- a groove 8 is provided, the is suitable to accommodate a spring ring 9.
- a coil spring 10 placed which has a lower end 11 and an upper end 12.
- the circumferential groove 8 a spring ring 9 on which the lower end 11 of the Coil spring 10 is present.
- the upper end 12 is the Coil spring 10 on the peripheral edge 14 of the slide bowl 13 on.
- the ball piece 6 has incisions 20 to one Swiveling the lever 7 in relation to the assembly part 5 allow.
- the operation of the socket wrench according to the invention is the following:
- the ball 6 becomes uniform over the spring 10 burdened and at the same time it is ensured that the Ball piece 6 inside the sliding bowl 13 a soft and can perform unimpeded movement.
