Abstract: The present invention discloses a driving system for a belt axis of a winch in the field of mechanics, which addresses the problems existing in conventional driving systems, such as a complicated structure and poor reliability. The driving system for the belt axis of the winch is positioned at the extension end of the belt axis on one side of a winch support. The driving system includes a rotary body and a fixed base, in which the fixed base is connected to the extension end of the belt axis via a connection means and the inner end of the rotary body is set on the fixed base. An insertion pore is positioned at the outer end of the rotary body. A spring is provided between the rotary body and the fixed base, under the action of which the inner end face of the rotary body is attached to the outer end face of the fixed base.

Abstract: The present invention discloses a device for fixing a rod-like apparatus in the field of mechanics. The existing problems of the device for fixing the rod-like apparatus, such as infirm fixation and low reliability, are addressed by using the device of the invention. The fixing device of the invention includes a body having a cavity in the interior. One or more notches having recessions are provided on the body. The notches have one or more holding pawls which could be opened and closed at the ends thereof. One or more positioning mechanisms are further provided in the body which could lock the holding pawls, in particular, lock the holding pawls when the notches of the body are closed by the holding pawls. The device of the invention could provide the benefits such as firm fixation, high reliability, an orderly and aesthetic appearance and relatively high practical value.

Abstract: The present invention provides a force measuring rigid load binder in the field of goods holding. The force measuring rigid load binder of the invention address the problems of conventional force measuring rigid load binders, such as potential damages to goods, adverse affection on goods transportation, increased difficulty in manual control, time and labor consumption and inconsistent tensioning forces of the binding belt. The force measuring rigid load binder of the invention includes a tensioning mechanism having a handle. Each of both ends of the tensioning mechanism is connected with a hook respectively. The tensioning mechanism is made of a rigid material. The distance between two hooks could be adjusted by the tensioning mechanism when the handle is pulled. A sensor is provided at a forced part of the tensioning mechanism, which could generate a signal corresponding to the size of the tensioning force when the load binder is in operation.
