Connecting piece with fine adjusting function

Abstract

The invention relates to a connecting piece with a fine adjusting function. The connecting piece is characterized in that the connecting piece comprises a screw, a bearing part, an expansion nail, a spring ring and a connecting rod; an opening is formed in the rear end of the screw; the front end and the rear end of the bearing part are each in a step shape; the outer diameter of the front end ofthe bearing part is smaller than the outer diameter of the rear end of the bearing part and the inner diameter of the opening; the front end of the bearing part has elasticity; an expansion opening isformed in the middle of the front end of the bearing part; the expansion nail is matched with the expansion opening to enable the outer diameter of the front end of the bearing part to be increased;the spring ring is arranged between the rear end of the bearing part and the opening; and a mounting groove is formed in the rear end of the bearing part, and the connecting rod is arranged in the mounting groove. The connecting mode can be flexibly adjusted, and in the using process, vibration between devices can be absorbed without directly applying force to the connecting rod.

Description

technical field [0001] The invention relates to a connecting piece, in particular to a connecting piece with a fine-tuning function. Background technique [0002] In the connection of multi-section equipment, straight-line connecting rods (or limit rods) are often used to arrange the devices in a straight line. The existing connecting rods are mostly installed through the rings directly fixed on the equipment. However, this connection method has the following two problems. First, it is not flexible enough and cannot be adjusted according to the needs of the environment. Second, some devices will vibrate during use, and the vibration frequency and amplitude of each device are not exactly the same, which will lead to connection problems. The rod is stressed at various positions and is prone to breakage after fatigue. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a connecting piece that can flexibly adjust the co...
