The invention belongs to the technical field of jacking devices, and particularly relates to a jacking device capable of being finely adjusted up and down, which comprises a fixed part and a lifting part, the fixed part comprises a base and a guide rod arranged on the base, and the lifting part is provided with a lifting plate, a climbing mechanism and an adjusting handle for controlling the climbing mechanism. The adjusting grip is pressed to drive the climbing mechanism so as to control the lifting part and the lifting plate to move upwards along the guide rod, the lifting part is further provided with a locking mechanism clamped with the guide rod, the locking mechanism limits the lifting part to move downwards, the lifting plate is arranged on the lifting part in a sliding mode, and an adjusting mechanism is arranged between the lifting part and the lifting plate. The lifting plate can be controlled to move up and down relative to the lifting part by driving the adjusting mechanism, so that downward or upward fine adjustment of the lifting part by the lifting plate is realized, and the jacking device can select fine adjustment of the ascending distance or the descending distance of an object according to actual requirements of a user; and therefore, the user can accurately and finely adjust the lifting height of the article conveniently, and the user can conveniently use the lifting device to work.
本发明属于顶高器技术领域,特指一种可上下微调的顶高器,包括固定部和升降部,固定部包括底座和设置在底座上的导向杆,升降部上设有升降板、爬升机构和控制爬升机构的调节握把,按压调节握把驱动爬升机构从而控制升降部及升降板沿导向杆向上移动,升降部上还设有与导向杆相卡接的锁止机构,锁止机构限制升降部向下移动,升降板滑动设置在升降部上,升降部与升降板之间设有调节机构,驱动调节机构可控制升降板相对于升降部上下移动,从而实现升降板对于升降部向下或向上的微调,是一种能够根据用户的实际需求来选择微调物品上升距离或微调物品下降距离的顶高器,从而便于用户能够精准的微调物品的抬升高度,有利于用户使用抬高器作业。
