Description

Lifting device Technical Field The utility model relates to the field of trailers and motor home, in particular to a lifting device. Background When the trailer is separated from the tractor, the trailer support legs are used for supporting the trailer and keeping the parking of the trailer stable. For a motor home, the mounting support legs can assist the bearing of the tire, so that the service life of the tire is prolonged. In order to facilitate the adjustment of the supporting angle of the supporting leg and the retraction of the supporting leg before the train, the Chinese patent application publication No. CN202245911U discloses a jack for a carriage, which is characterized in that a positioning piece positioned by a deflection device is arranged on the top surface of an outer cylinder, and the deflection device deflects and positions the positioning piece at any preset angle. The positioning piece is a U-shaped body, the positioning piece is provided with a pin joint hole, a plurality of insertion holes and a clamping hole for clamping, the deflection device is provided with a positioning disk and a pull handle, the periphery of the positioning disk is provided with a plurality of surrounding positioning holes and a central hole, the pull handle is inserted into one insertion hole by a positioning column, the insertion posts are inserted into the insertion holes, a bolt is inserted into the pin joint hole of the positioning piece and the central hole of the positioning disk, the positioning piece is pivoted to the outer cylinder, and the positioning disk is further fixed to the outer cylinder. When the pull rod is used, the inner surface of the pull rod is propped against the pull ring by pulling the pull rod for a certain distance, and then the pull rod is pulled together with the pull ring for a certain distance, so that the pull ring drives the plunger, the plunger is temporarily separated from the positioning hole of the positioning disc, the deflection positioning piece is deflected for a certain angle by the pull rod, then the pull rod is opened, the pull ring and the plunger are recovered by elasticity, and the plunger is inserted into the positioning hole of the positioning disc, so that the positioning piece is positioned for a certain angle to prop up a supported object. The scheme has the following problems that firstly, the pull ring is easy to wear in the process of frequently contacting with the pull handle, and the risk of locking failure of the plug is caused, and secondly, operators need to directly overcome the elasticity of the elastic piece to do work, so that the use is laborious. Disclosure of Invention The utility model provides a lifting device which is reliable in locking, convenient to operate and labor-saving, and aims to solve the technical problems that a locking device of the existing lifting device is invalid in locking and inconvenient to operate. The utility model provides a lifting device which comprises a supporting leg, a swinging seat, a fixed seat and a swinging adjusting structure, wherein one end of the swinging seat is connected with the supporting leg, the other end of the swinging seat is connected with the fixed seat, the fixed seat and the swinging seat can swing relatively, a locking hole is formed in the fixed seat, an adjusting disc is arranged on the swinging seat, an adjusting hole is formed in the adjusting disc, the swinging adjusting structure comprises a handle, a locking frame and a locking pin, the locking frame is arranged between the handle and the fixed seat, one end of the locking pin is connected with the handle, the other end of the locking pin penetrates through the locking frame, the locking hole and the adjusting hole and can enter and exit along the adjusting hole, and a flange is arranged at one end of the handle.
