Abstract: This inventions involves a type of multi-node operating handle and elastic connecting device for non-cylinder shear jack; the front node handle is provided with two perforated holes used for locking of pin to facilitate the axle and hole coordination; the rear node handle is provided with three prefabricated holes for rivet joint, which makes use of two rivets to realize the serial connection of elastic metal sheet with locking pin and rear node handle as well as the pressing rivet joint of rivets; furthermore, both front and rear node handles have non-cylinder coordination available for better transfer of torsion moment, which can be used to shape the locking pin on the body of elastic metal sheet through pressing. Favorable effects of this invention are stated as follows: the handle structure and connecting device as described in this proposal can facilitate the length combination of operating handle in accommodation with lifting under different loads, which can ensure the reliability of the handle in use.

Abstract: A type of illuminating device used to horizontal jack, of which, the middle part of the axial hole of tray axle (1) is provided with insulating filling (6) and transparent polymethylmethacrylate sheet (10); the positioning set (11) under the polymethylmethacrylate sheet (10) is equipped with LED illuminating bulb (13) and relevant circuit elements to form the loop of the illuminating circuit available for control of switch-on and switch-off; the illuminating device of this invention is integrated on the central part of the tray of horizontal jack, which makes full use of the space of tray axial hole to ensure the reliable operation of illuminating elements and relevant circuits with its sound sealing performance for the purpose of improving the poor illumination and solving the problem with maintenance of vehicles and lifting of heavy goods at night.

Abstract: This invention involves a type of connecting device for handle operation, including front node handle, rear node handle and locking pin.
