Problems solved by technology

[0002] At present, in the installation of some large objects or in the maintenance process of automobiles, due to the heavy weight of large objects and automobiles, in the actual operation process, sometimes it is necessary to use lifting tools such as jacks to perform corresponding operations to improve Work efficiency, most of the jacks that are widely used in the market are scissor jacks. Generally, the jack needs to be equipped with a special jack turning wrench when using it. However, most of the existing jack turning wrenches are separated from the jack body after use. storage, it is easy to lose during the subsequent storage process, causing inconvenient use

Abstract

The invention discloses a hydraulic jack which comprises a jack body and a sleeve movably installed on the jack body. The sleeve is provided with an open end and a closed end, a multi-stage telescopic rod is installed at the open end of the sleeve, and the multi-stage telescopic rod can be retracted into the sleeve; and a locking piece for locking the multi-stage telescopic rod in the sleeve is arranged at the closed end of the sleeve. The hydraulic jack is novel in design and easy to operate, and due to the arrangement of the multi-stage telescopic rod, the multi-stage telescopic rod is shrunk in the sleeve and is not prone to being lost; the multi-stage telescopic rod is drawn out of the sleeve and can be used as a rotating wrench to work; through the arrangement of the locking piece, when the jack body is not used, the locking piece can lock the multi-stage telescopic rod in the sleeve, and carrying and using are convenient; and through arrangement of a stop block and a through hole, the locking effect of the locking piece on the multi-stage telescopic rod in the sleeve can be further enhanced.

Description

technical field [0001] The invention relates to the technical field of jacks, in particular to a hydraulic jack. Background technique [0002] At present, in the installation of some large objects or in the maintenance process of automobiles, due to the heavy weight of large objects and automobiles, in the actual operation process, sometimes it is necessary to use lifting tools such as jacks to perform corresponding operations to improve Work efficiency, most of the jacks that are widely used in the market are scissor jacks. Generally, the jack needs to be equipped with a special jack turning wrench when using it. However, most of the existing jack turning wrenches are separated from the jack body after use. It is easy to lose during the subsequent storage process, causing inconvenience in use. Contents of the invention [0003] Based on the technical problems in the background technology, the present invention proposes a hydraulic jack, including a jack body and a sleeve...
