Vibration-out rod

Abstract

The invention provides a low-cost vibration-out rod capable of preventing each section from being fixedly connected, rotating and the like by means of a simple structure. The vibrating-out rod (10) iscomposed of a plurality of sections (11-17). A reduced-diameter section (27) and a fitting recess (26) are formed on the inner side of the tip section (20) of the fifth joint (15) from the tip side (24) to the rear end side (25). The inner surface (29) of the fitting recess (26) is inclined at a taper ratio T1. The reducing part (27) reduces the diameter of the tail end opening of the fifth joint(15). A first fitting protrusion (36) and a second fitting protrusion (37) are formed at the rear end (21) of the fourth joint (14) from the rear end side (25) to the distal end side (24). The diameter of the first fitting protrusion (36) is gradually reduced toward the distal end side (24) with a taper ratio T2. The diameter of the second fitting protrusion (37) is gradually reduced toward the distal end side (24) at a taper ratio T3. And each taper ratio meets the condition that T1 is greater than or equal to T3 and less than T2.

Description

technical field [0001] The present invention relates to the construction of so-called swing-out fishing rods. Background technique [0002] The so-called vibrating-type fishing rod and netting rod (玉の抯) (hereinafter referred to as "vibrating rod") are composed of a plurality of sections, and each section is assembled to form a telescopic sleeve. Each segment is generally made of a resin reinforced with carbon fiber, and among the plurality of segments, the smallest outer diameter is called the first segment and the second segment in order, and the largest outer diameter is called the female segment. The female section is the part that the angler holds when operating the vibrating rod, and the section arranged inside the female section is called the sub- female section. During actual fishing, it is required that the vibrating pole be extended and shortened rapidly and smoothly. [0003] As mentioned above, each section constitutes a telescopic sleeve. Therefore, for example...

Problems solved by technology

[0008] However, it is not easy to form the joint preventing grooves, the locking grooves and the locking protrusions for preventing rotation, and there is a problem that the manufacturing cost of the joints increases significantly.
