阅读说明：本技术 一种杠杆加滚动方式触发的自动钓鱼器 (Automatic fishing device triggered by lever and rolling mode ) 是由 吴明义 于 2019-08-16 设计创作，主要内容包括：一种杠杆加滚动方式触发的自动钓鱼器,一根下部有支撑面的支撑杆上从上到下安置有拉簧、滑管、D形环。浮漂与主线或支撑杆上部连接,拉簧下端与滑管连接,D形环与滑管连接,D形环直形部位有圆柱体。主线连接支撑杆上端而子线连接D形环上的鱼线孔,或者主线穿过支撑杆上端的过线环、D形环上的鱼线孔再连接子线,安装时使滑管下移拉伸拉簧,然后将D形环的直形部位圆柱体放在支撑面上；鱼吃饵时子线下拉D形环使圆柱体在支撑面上向外滚动脱离支撑面,拉簧瞬间上拉D形环带动子线上行,鱼钩回缩钓住鱼。本钓器以杠杆加滚动方式触发,具触发力小、性能可靠稳定、安装方便、不乱线、成本低、能提示钓器触发与否及暂锁预防远投时钓器误触发的优点。(An automatic fishing device triggered by lever and rolling mode features that a supporting rod with supporting surface is equipped with tension spring, slide tube and D-shaped ring from top to bottom. The float is connected with the main line or the upper part of the support rod, the lower end of the tension spring is connected with the sliding pipe, the D-shaped ring is connected with the sliding pipe, and the straight part of the D-shaped ring is provided with a cylinder. The main line is connected with the upper end of the supporting rod, and the sub-line is connected with the fish line hole on the D-shaped ring, or the main line passes through the line passing ring at the upper end of the supporting rod and the fish line hole on the D-shaped ring and then is connected with the sub-line, the slide pipe moves downwards to stretch the tension spring during installation, and then the straight part cylinder of the D-shaped ring is placed on the supporting surface; when the fish eats the bait, the D-shaped ring is pulled downwards by the sub-line to enable the cylinder to roll outwards on the supporting surface to be separated from the supporting surface, the tension spring instantly pulls the D-shaped ring upwards to drive the sub-line to move upwards, and the fishhook retracts to fish the fish. The fishing device is triggered in a lever and rolling mode, and has the advantages of small triggering force, reliable and stable performance, convenience in installation, no messy lines, low cost and capability of prompting whether the fishing device is triggered or not and preventing the fishing device from being triggered mistakenly when the fishing device is shot far by temporary locking.)

1. An automatic fishing device triggered by a lever and rolling mode is characterized in that the upper end of a strip-shaped supporting rod is provided with a main line fastening hole, a pressure spring is sleeved on the supporting rod or the upper part of the supporting rod is provided with a tension piece fastening hole; there is the holding surface in the lower part of bracing piece, and the holding surface divides the disc to divide lamella form and step form two kinds, but the bracing piece has three kinds: the first method comprises the following steps: the supporting rod is a round rod-shaped, the lower part of the round rod-shaped supporting rod is expanded into a disc, and the disc is divided into split supporting surfaces by the grooves; and the second method comprises the following steps: the support rod is flat or rectangular, and the lower part of the support rod is provided with 1 step-shaped support surface; and the third is that: the support rod is flat or rectangular, and the lower part of the support rod is provided with 2 step-shaped support surfaces; the tension piece is a tension spring or a rubber band, the upper end of the tension piece is connected with a tension piece fastening hole at the upper part of the supporting rod, the lower end of the tension piece is movably connected with a cylinder at the straight part of the D-shaped ring, or the upper part of the tension piece is connected with a tension piece fastening hole of the supporting rod, the lower end of the tension piece is connected with a sliding tube tension piece fastening hole at the upper part of a sliding tube sleeved on the supporting rod, then the lower part of the sliding tube is connected with the cylinder at the straight part of the D-shaped ring through D-shaped ring connecting holes at two side walls of the sliding tube, the other parts of the straight part of the D-shaped ring except two ends and the part connected with the ring arm of the D-shaped ring are cylinders, the straight part of the D-shaped ring is fixedly connected with the ring arm of the D-shaped ring or the straight part of the D-shaped; when the pressure spring is adopted, the upper end of the pressure spring sleeved on the supporting rod is movably connected with the cylinder at the straight part of the D-shaped ring through an extended spring wire or a 8-shaped ring, a metal straight wire or other flexible wires of the connecting piece; the main line is connected with a main line bolt hole at the upper end of the supporting rod, the sub line is connected with a fishing line hole on the D-shaped ring, the float is connected on the main line above the upper end of the supporting rod, the main line above the float is provided with space beans, the fishing depth is adjusted by moving the space beans on the main line, when the fishing device is installed before fishing, the straight part of the D-shaped ring moves downwards or the sliding tube moves downwards to stretch a tension piece or compress a pressure spring, then the cylinder of the straight part of the D-shaped ring or the cylinder of the straight part of the D-shaped ring in the sliding tube hole is placed on the supporting surface of the supporting rod, namely the D-shaped ring is hung on the supporting surface of the supporting rod, and the end of the D-shaped ring with the fishing line hole rotates to the side of the supporting rod to ensure that the intersecting angle of the ring arm of the D-shaped ring and the longitudinal axis of the supporting rod is visually measured to be a right angle, after the fishing device is installed and thrown into water, when, the cylinder at the straight part of the D-shaped ring or the cylinder at the straight part of the D-shaped ring in the tube hole of the sliding tube rolls outwards on the supporting surface of the supporting rod in a lever force and rolling mode until the D-shaped ring is separated from the supporting rod, and the D-shaped ring moves upwards under the pulling force of the tension piece or the elastic piece, so that the sub-line is driven to move upwards, and the fishhook retracts to fish.

2. The automatic fishing device as claimed in claim 1, wherein when the support rod is formed in a flat or rectangular shape and has 1 or 2 stepped support surfaces at a lower portion thereof, the support rod has a support rod extension downwardly from the support surface, and the support rod extension has a thin film pin hole at a distal end thereof.

3. The automatic fishing device as claimed in claim 1, wherein the D-ring has a downward extension when the support rod is oblong or rectangular and the lower portion thereof has 1 or 2 stepped support surfaces.

4. The automatic fishing device as claimed in claim 1, wherein when the support rod is oblong or rectangular and the lower portion thereof has 1 or 2 step-like support surfaces, the line group is connected in a straight-through manner, the sliding tube has the backstop or the straight portion of the D-shaped ring has the backstop of the straight portion of the D-shaped ring formed by the obliquely upward extending section or the loop arm of the D-shaped ring has the backstop of the upward extending section of the loop arm of the D-shaped ring formed by the obliquely upward extending section.

5. The automatic fishing device as claimed in claim 1, wherein when the support rod is formed in a flat or rectangular shape and the lower portion thereof has 1 or 2 stepped support surfaces and the line groups are connected in a straight-through manner, the upper portion of the support rod has a line passing ring or the upper portion of the support rod is connected to a float having a line passing hole.
