Abstract

The invention discloses an angle-adjustable jack which comprises a scissor jack. A support block is fixedly connected to the lower side of a base of the scissor jack and is connected with a second screw in a threaded manner, the second screw is supported by a square frame, the square frame comprises two second support plates and two third support plates, the second support plates support the second screw, the third support plates are parallel to the second screw, slide grooves are respectively arranged on the third support plates, and the support block is slidably connected into the slide grooves. As the screw is connected with the second support plates and the third support plates in a threaded manner, the jack can be aligned by means of finely adjusting the screw. The angle-adjustable jack has the advantages that the offset jack can be easily aligned by means of finely adjusting the screw, normal troublesome steps are omitted, and the jack alignment accuracy is guaranteed.

Description

technical field [0001] The invention belongs to a jack with adjustable angle. Background technique [0002] Jack is a kind of light and small lifting equipment that uses a rigid top lifting part as a working device, and lifts a weight in a stroke by a top bracket or a bottom claw. According to the structural characteristics, it can be divided into three types: rack jack, screw jack and hydraulic jack. Jack is the simplest lifting equipment with a small lifting height (less than 1m). It has two kinds of mechanical and hydraulic. There are two types of mechanical jacks, the rack type and the screw type. Due to the small lifting capacity and laborious operation, they are generally only used for mechanical maintenance work, and are not suitable for bridge repairing. The hydraulic jack has compact structure, stable operation and self-locking effect, so it is widely used. Its disadvantage is that the lifting height is limited and the lifting speed is slow. The types of car ja...
