Embodiment Construction

[0009] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0010] Inserting rods, including a central rod 1, the outer circumference of the central rod 1 is provided with at least 4 arc-shaped grooves 2, the arc-shaped grooves 2 are parallel to the axial direction of the central rod 1, and the axial direction of the central rod 1 There is a threaded hole 3 in the center, and also includes a sliding sleeve. The sliding sleeve includes a first connecting part 4. The first connecting part is provided with a through hole with the same shape as the central rod. The sliding sleeve also includes a second connecting part. Part 5, the second connecting part is a ring sleeve, and the ring sleeve is connected to the outer periphery of the first connecting part by threads.

Abstract

The invention relates to the field of tool accessories, in particular to an insertion rod. The insertion rod comprises a center rod and a slide bushing, at least four arc grooves are arranged in the periphery of the center rod, each arc groove is parallel to the axial direction of the center rod, a threaded hole is arranged in the center of the axial direction of the center rod, the slide bushing comprises a first connecting portion and a second connecting portion, a through hole identical to the center rod in shape is arranged in the first connecting portion, the second connecting portion is a ring sleeve, and the ring sleeve is connected to the periphery of the first connecting portion through a thread. The insertion rod has the advantages that the arc grooves in the periphery of the center rod can adapt to protrusions inside tubular workpieces, smooth insertion can be achieved, and connection and fastening of two tubular workpieces are realized by the slide bushing.

Description

technical field [0001] The invention relates to the field of tool accessories, in particular to a plug-in rod. Background technique [0002] In the process of connecting two independent tubular workpieces, a splice rod is usually used to connect the two tubular workpieces, while the traditional splice rod is a straight rod body. When inserted into the tubular workpiece, Insertion may not be possible due to protrusions inside the tubular workpiece. Contents of the invention [0003] The object of the present invention is to propose a splicing rod. The arc-shaped groove around the center rod can adapt to the protrusion inside the tubular workpiece and can be inserted smoothly. At the same time, the sliding sleeve realizes the connection and fastening of two tubular workpieces. [0004] The technical scheme that realizes the object of the present invention is as follows: [0005] Inserting rods, including a central rod, the outer periphery of the central rod is provided wit...
