摘要:
A work machine includes a main pole internally including a rotation shaft, a tool unit located at one end of the main pole, and a power unit located at another end of the main pole. The main pole includes a first partial pole, a second partial pole and a joint member that joints them to each other. The first partial pole includes a positioning member. The joint member includes a positioning hole configured to engage with the positioning member and a guide groove extending from the positioning hole. The guide groove is configured to guide the positioning member to the positioning hole and to allow the positioning member to escape in at least a section thereof.

Filamentary fixation devices may be used in a variety of surgical procedures to secure soft tissue to bone. The present invention provides various devices, systems, kits and instrumentation for performing such surgical procedures including preparation of soft tissue and bone, preparation and manipulation of such filamentary fixation devices, and insertion and utilization of the fixation devices within a patient's anatomy. In one embodiment, a method for securing soft tissue to bone, the method includes accessing the soft tissue and the bone, passing a filament through the soft tissue, preparing a bore hole in the bone, loading the filament into a filamentary fixation device, implanting the filamentary fixation device, with the filament, into the bore hole, and tensioning the filament so that the filamentary fixation device and filament are secured within the bore hole.

The disclosed embodiments describe a method for producing a bent tubular shaft for a tubular shaft instrument as well as a tubular shaft produced in such manner as well as a tubular shaft instrument with such a bent tubular shaft. The tubular shaft is produced by providing a hollow shaft component and an actuating rod. The actuating rod in this case has at least one bending area in which flexible segments and support segments alternate. The at least one bending area of the actuating rod is provided with a friction-reducing layer before it is inserted into the shaft component in order to create a tubular shaft. The tubular shaft is then bent in an area that corresponds to the at least one bending area of the actuating rod.

A system for transmitting power from a drive shaft to a seed meter shaft of a seeder is disclosed. The system comprises a first transmission that connects to one of the drive shaft and the seed meter shaft. The first transmission also connects to a clutch assembly. The clutch assembly connects to a flexible drive shaft assembly, and the flexible drive shaft assembly connects to a second transmission. The second transmission connects to the other of the drive shaft and the seed meter shaft. The clutch assembly is detachable from the first transmission and the flexible drive shaft assembly and the flexible drive shaft assembly is directly connectable to the first transmission.
