Fig. 4 is a component diagram of the tube assembly of the present embodiment, which includes a tension spring 5, an 8-shaped swivel connector 9, an elbow 8-shaped trigger 6, and a connecting wire 8. The trigger member 6 of the elbow 8 shape used in the present embodiment is substantially an 8-shaped ring, which is one of trigger members without circular arc legs, and the upper portion thereof, i.e., the rolling portion 11 thereof, is not perfectly straight but is a curved circular strip (see fig. 45 and 46 and fig. 43 and 44 and their description).

Fig. 5 is a shape view of the upper end of the tube after the assembly inside the tube 1 is placed, showing the upper end of the tension spring 5 hung on the elastic member hanging bar 2.

Fig. 6 is a view showing the state in which the in-duct assembly is pulled outward from the lower end of the duct just before fishing, in which the elbow 8-shaped trigger 6 has been pulled out of the lower end of the duct and the lower end of the 8-shaped swivel connector 9 has been pulled to the mouth of the pipe.

Fig. 7 is a slightly upward view of the fishing device in a standby state after the trigger device is installed, a float is connected to a main line 10, a connecting line 8 and a sub-line 7 are shown in the figure, the lower end of an 8-shaped swivel connector 9 is shown to enter a bayonet 3, a rolling part 11 at the upper part of an elbow 8-shaped trigger 6 is placed or hung on a concave supporting surface 4, the elbow 8-shaped trigger 6 is rotated to enable the vertical axis of the elbow 8-shaped trigger 6 to be approximately right-angled by visual observation with respect to the vertical axis of a pipe 1, namely the elbow 8-shaped trigger 6 is approximately horizontal after the fishing device is put into water, fish eat a bait retractor, and the rolling part 11 at the upper part of the elbow 8-shaped trigger 6 rolls to be separated from the bayonet 3 and the concave supporting surface 4 to trigger the fishing device.

The elbow 8-shaped trigger 6 is used in the embodiment, because the bayonet 3 exists and the upper part of the elbow 8-shaped trigger 6, namely the rolling part 11, is axially bent, after the rolling part 11 is placed on the supporting surface 4 and the elbow 8-shaped trigger 6 is rotated, one end of the connector line of the elbow 8-shaped trigger 6 slightly tilts downwards, which has certain influence on throwing and fishing, but still can be used, and the elbow 8-shaped trigger has the advantage that the lower part of the 8-shaped swivel connector 9 connected with the elbow 8-shaped trigger 6 is easily and automatically centered on the upper part of the elbow 8-shaped trigger 6, namely the rolling part. If a flat head 8-shaped trigger with a straight part at the upper part is adopted for the concave supporting surface of the embodiment, the defects are avoided, but the lower part of the tension spring or the 8-shaped swivel connector connected with the upper part of the flat head 8-shaped trigger needs to be centered on the upper part of the suspension ring manually during installation, but if an annular groove is arranged at the middle position of the rolling part of the flat head 8-shaped trigger and used for accommodating the lower part of the tension spring or the 8-shaped swivel connector or the lower part of the pull wire of the pressure spring, the flat head 8-shaped trigger and the lower part do not need to be centered manually during installation.

In this case, the D-shaped trigger 12 is fixedly connected to the shaft 14, but the D-shaped trigger may be directly wound with a material without a split connection mode in which a shaft is connected to a U-shaped body, for example, a D-shaped ring is wound by bending a round wire as the D-shaped trigger, at this time, a straight portion of the D-shaped trigger and the U-shaped ring are in an integrated continuous structure, although the D-shaped trigger does not have a shaft on the surface, a straight portion of the D-shaped trigger and the U-shaped body are still in an integrated continuous structure as a shaft, and a U-shaped connector may also be wound with a round wire and connected to a straight portion of the D-shaped trigger wound with the round wire, and the form and the effect of the D-shaped trigger and the U-shaped connector are the same as those of the D-shaped trigger and the U-shaped connector having shafts. Namely, according to the use requirement, the D-shaped trigger piece is composed of a U-shaped body and an axle or is formed by winding materials or casting and forging the materials.

FIG. 10 is a view of the assembly in the tube pulled out of the lower port of the tube. In the figure 1 a tube, 12 a D-shaped trigger, 13 a U-shaped connector and 14 a shaft, the next operation will be to place the rolling part 11 on the convex support surface 17. If the upper and lower positions of the U-shaped connector 13 and the D-shaped trigger member 12 are exchanged, that is, if the U-shaped connector 13 is exchanged to be arranged at the lower part, the D-shaped trigger member 13 is arranged at the upper part, and the effect is the same.

Fig. 11 shows a view from below looking up when the rolling part 11 on the upper part of the D-shaped trigger 12 has been placed on the convex support surface 17 and the tension of the tension spring 5 has been supported by the support surface 17 to set the fishing tackle in a cocked state. In the figure, 1 is a pipe and 13 is a U-shaped connector.

Fig. 12 is a view of the fishing device in a cocked state with the rolling part 11 of the D-shaped trigger 12 placed on the convex support surface 17. since the D-shaped trigger 12 is fixedly connected with the shaft 14, when the trigger 12 is pulled downwards by a fish bait-pulling hook, the rolling part 11 rolls off the support surface 17 to trigger the fishing device.

FIG. 13 is a side view of the fishing device in a standby state, in which a main line 10 is connected with the upper part of a pipe 1, a float is connected to the main line, and the fishing depth can be adjusted by moving the float on the main line; the lower part of the connecting line 8 is connected with the sub-line of the fishhook, and the D-shaped trigger 12 is in a horizontal state.

In the figure 8 is a connecting line.

Fig. 16 is a sub-bottom view from below and looking up from the side, with the rolling part 11 of the trigger piece 19 of the truncated 8 shape already placed on the V-shaped support surface 20, and the fishing tackle in a cocked state. The rolling part 11 of the flat head 8-shaped trigger 19 is a cylinder (see fig. 39, 40 and 43 and their description), 18 is a rubber band, and 8 is an 8-shaped swivel connector.

Fig. 17 is a side view at a slightly elevated angle of the fishing tackle in a ready-to-trigger state, when the fish eats the bait-pulling hook, the flat-head 8-shaped trigger 19 will roll the rolling part 11 on the V-shaped supporting surface 20 to the wider pipe orifice, so that the flat-head 8-shaped trigger 19 is contracted into the pipe 1 to trigger the fishing tackle.

FIG. 18 is a side view of the armed state of the fishing device, in which 8 is a sub-line, 10 is a main line, and 19 is a flat-head 8-shaped trigger.

The fourth embodiment (fig. 19-23) is another embodiment of the D-shaped trigger + U-shaped connector, i.e., the D + U version. The two rolling parts (namely two feet containing arc bodies) of the D-shaped trigger piece are placed on the circular ring-shaped supporting surface in the pipe wall end surface supporting surface at the lower end of the pipe, the U-shaped trigger piece, the U-shaped connector, the V-shaped trigger piece, the delta-shaped trigger piece, the D-shaped ring connector and the D + U scheme are summarized in the description of the attached drawings of the embodiment.

In this embodiment:

fig. 19 is a structural diagram of an in-tube assembly in the 4 th embodiment, in which the in-tube assembly is composed of a tension spring 5, an 8-shaped swivel connector 9, an O-ring connector 21, a U-shaped connector 13, a D-shaped trigger 12, and a connecting wire 8, wherein the D-shaped trigger 12 is a leg including an arc body, and unlike the second embodiment which is also the D + U embodiment, in this embodiment, two legs including an arc body of the D-shaped trigger are used as the rolling portion 11 instead of the middle portion of the shaft 14.

Fig. 20 is a view showing the shape of a circular supporting surface 23 to which the entire lower circular end surface of the pipe wall of the pipe 1 belongs. In practical manufacturing, a polygonal pipe can be used instead of a round pipe, and when the polygonal pipe is used, the supporting surface of the end surface of the pipe wall is also in a polygonal shape, for example, if a square pipe is used, the supporting surface of the end surface of the pipe wall has an option of a square supporting surface. The polygonal tube is characterized by having a plurality of sections of straight tube wall end faces, wherein each side of the polygon is a section of straight tube wall end face, and the number of the sides is the number of the sections of straight tube wall end faces. Of course, the wall end surface of the lower end of the circular tube can also be made into a straight wall end surface. For example, the V-shaped support surface described above comprises two straight tube wall end surfaces. When in selection, the pipe wall end face of the lower end of the whole pipe is used as the pipe wall end face supporting face, or only part of the pipe wall end face of the lower end of the pipe is used as the pipe wall end face supporting face. In this figure 8 is a connecting line showing that the assembly in the tube has been received in the lumen of the tube 1.

Fig. 21 is a view of the fishing device in a state to be triggered according to the embodiment, when two rolling parts 11 at the ends of the ring arms 15 of the D-shaped trigger 12 are placed on the circular ring-shaped supporting surface 23 at the end surface of the pipe wall, the connecting line 8 of the connecting sub-line 7 below the rolling parts will pull the D-shaped trigger 12 when the fish eats the bait retractor, so that the rolling parts 11 of the D-shaped trigger 12 roll to a wider pipe orifice on the circular ring-shaped supporting surface 23 and are quickly pulled into the pipe cavity by the pulling force of the elastic element to trigger the fishing device. In this embodiment, the D-shaped trigger 12 and the shaft 14 may be fixedly or movably connected. The rolling portions in this embodiment are two circular arc legs of the D-shaped trigger 12, and as can be seen from the figure, the two circular arc legs are of a non-complete cylindrical structure, because the legs containing the circular arc bodies have no straight section but are circular arc legs without straight sections, but only have a part of the circular arc body structure and a part of the circular arc body structure, namely a part of the circular arc body structure is of a one-piece continuous structure with other parts of the trigger, namely the ring arm 15. The two rounded feet as the rolling portions can also be made into a non-perfect cylindrical structure with straight sections if necessary for the purpose of fishing large fish for long throw and heavy bait (see fig. 40, 42, 47, 48 and their description). In actual manufacturing, the circular arc foot is not necessarily made into an enlarged wheel shape as in the embodiment, that is, the circular arc foot may be made into the same size as the part connected with the trigger, but it is only necessary to make the circular arc foot have the necessary circular arc structure and make the connecting part of the U-shaped connector connected with the circular arc foot smaller than the connecting part. In the figure, 1 is a pipe, 10 is a main line, and 13 is a U-shaped connector.

As can be seen from the drawings of the present embodiment, the middle portion of the shaft 14 is omitted and the two circular arc-shaped legs of the D-shaped trigger are used as the rolling part 11, so if the middle portion of the shaft 14 is omitted and the two head portions of the shaft 14 are remained to form a combination body in which two U-shaped bodies are connected by two short shafts, the U-shaped body located at the lower side can be used as the trigger and the two circular arc-shaped legs thereof can be used as the rolling part, which is the U-shaped trigger, while the U-shaped body located at the upper side is still a U-shaped connector.

Furthermore, it can be considered from the view of the present embodiment that the D + U solution is formed by connecting the upper and lower U-shaped bodies with a shaft, so it can be inferred that it is also feasible to exchange the positions of the upper U-shaped connector and the lower D-shaped trigger, but it is necessary to make the two arc-shaped feet as the rolling parts larger.

In addition, as can be seen from the view of the embodiment, the U-shaped body is similar to the V-shaped body, and the U-shaped body can be changed into the V-shaped body to be used as a V-shaped connector or a V-shaped trigger part only by slightly changing the U-shaped body; it can be seen that the D-shaped ring is similar to the delta-shaped body, and can be changed into the delta-shaped body by only slightly changing the D-shaped ring to be used as the delta-shaped connector and the delta-shaped trigger, for example, when the D-shaped ring is used as the delta-shaped trigger, the rolling part is one of the three edges, or the arc foot.

From the recognition that the D + U solution is formed by connecting the upper and lower U-shaped bodies with a shaft according to the embodiment, the D-ring connector may be used as the connector at the upper part, and the U-shaped trigger may be used as the trigger at the lower part.

Fig. 22 is a bottom view of the fishing device in the cocked state, showing that both rolling portions 11 of the D-shaped trigger at the lower end of the pipe are placed on the circular ring-shaped support surface 23 among the support surfaces of the pipe wall end surfaces.

Fig. 23 is a side view of the fishing rod in a cocked state, wherein a float is connected to the main line 10, the D-shaped trigger 12 is substantially horizontal, and can be directly connected with the D-shaped trigger 12 by the sub-line 7 without a connecting line, most parts are hidden in the fishing rod, the fishing rod is attractive in appearance, and all parts can be plugged into the fishing rod after triggering and when the fishing rod is retracted, the fishing rod is convenient to store. In the figure, 11 denotes a scroll portion.

At the end of this embodiment, the following summary can be made: the second embodiment and the fourth embodiment adopt a D + U scheme of a D-shaped trigger and a U-shaped connector, when the scheme is adopted, the U-shaped connector can be adopted independently (for example, embodiment 2), and an 8-shaped swivel connector and the U-shaped connector can also be adopted (for example, the fourth embodiment); when the D + U scheme is adopted, the middle part of the shaft of the D-shaped trigger piece and the arc-shaped foot of the D-shaped trigger piece can be used as rolling pieces, namely, the D-shaped trigger piece can only have one rolling part or can simultaneously have two rolling parts.

Fig. 24 is a structural view of an in-pipe assembly of the 5 th embodiment, in which the connectors used are the 8-turn connector 9 and the 8-ring connector 24, and a linear trigger 25 having one circular arc leg thereof as the rolling portion 11 (it is also possible to refer to it as a 8-ring trigger because it has two holes). In the figure, 11 indicates both the arc-shaped leg of the linear trigger and the rolling part 11 of the linear trigger.

FIG. 25 is a view showing the ready-to-use fishing tackle according to the embodiment of FIG. 5, in which the linear trigger 25 has placed the rolling part 11 on the circular ring-shaped support surface 23 of the lower end of the pipe 1, and the linear trigger 25 is pulled by the fishing line 7 to roll the rolling part 11 off the circular ring-shaped support surface to trigger the fishing tackle.

Fig. 26 is a side view of the fishing tackle in a cocked state.

A sixth embodiment (fig. 27 to 30) is an embodiment in which a circular trigger is used for a circular support surface: the circular trigger part is characterized in that the rolling part and a sub-wire connecting hole on the trigger part are placed on a circular block, and the circular block is the trigger part and the rolling part.

Fig. 27 is a diagram of the pipe interior assembly of the present embodiment 6, which is composed of the tension spring 5, the 8-shaped swivel connector 9, the D-ring connector 49, and the

circular trigger

46, and 8 in the figure is a connecting wire, and the lower end of the connecting wire is connected to a sub-wire.

Fig. 29 is a shape view of the fishing tackle in a ready-to-trigger state, in which the pipe assembly is mounted in the pipe 1 and the circular trigger 46 is placed on the circular support surface 23 at the lower end of the pipe 1, and the fishing tackle is in a ready-to-trigger state. The connecting shaft 48 is a component of a D-shaped ring connector 49, the middle of the square of the two ends of the connecting shaft 48 is round, the center of the round triggering piece 46 is a round hole and is movably connected with the connecting shaft 48, in the figure, the round triggering piece connecting wire hole 47 on the round triggering piece 46 is penetrated with a connecting wire 8, the connecting wire is connected with a sub-wire, and if a fish eats the bait retractor, the connecting wire 8 is dragged to enable the round triggering piece 46 to roll and be separated from the circular supporting surface 23 to trigger the fishing tackle.

The circular arc-shaped feet are in a cylindrical structure or a large semi-cylindrical structure according to the requirement of high sensitivity (see fig. 40, 42, 47, 48, 43 and 44).

fig. 31 is an assembled view of the pipe interior assembly of the 7 th embodiment, which is composed of the tension spring 5, the 8-shaped swivel connector 9, the O-ring connector 21, the U-shaped connector 13, and the T-shaped trigger 16.

FIG. 32 is an enlarged fragmentary view of FIG. 31 showing the transverse portion of the T-shaped trigger member being a shaft 14, the T-shaped trigger member 16 being connected to the shaft 14 of the U-shaped connector 13, the rounded foot of the T-shaped trigger member 16 being the rolling portion 11, the U-shaped connector 13 being movably connected to the shaft 14; the T-shaped trigger 16 may be fixedly or movably connected to the shaft 14, which in this embodiment is fixedly connected.

FIG. 33 is a view showing the fishing tackle of the 7 th embodiment in a ready-to-trigger state, in which the pipe assembly is pulled out of the nozzle at the lower end of the pipe 1, the rolling portion 11 of the T-shaped trigger 16 connected to the U-shaped connector 13 is placed on the convex support surface 17, and the fishing tackle is in a ready-to-trigger state.

FIG. 34 is a view showing the fishing tackle from another perspective in a ready state, in which the fishing hook is pulled by the bait-pulling hook to pull the connecting line 8, and the rolling part 11 of the T-shaped trigger 16 is rolled off from the convex supporting surface 17 to trigger the fishing tackle. Figure 13 shows a U-shaped connector.

It can be seen from this figure that the rolling part 11 of the T-shaped trigger 16 can be hung on the supporting surface of the end face of the pipe orifice with slight modification, and the modification is to make the diameter of the rolling part of the T-shaped trigger 16 larger than the diameter of the connecting part of the U-shaped connector 13 and the shaft 14 and to bend the U-shaped connector properly toward the end face of the pipe wall.

It can also be seen from this figure that if the position of the T-shaped trigger 16 is exchanged with that of the U-shaped connector 13, i.e. the T-shaped trigger 16 is used as a T-shaped hanging connector and the U-shaped connector 13 is used as a U-shaped trigger, the two circular arc-shaped legs of the U-shaped trigger can be used on the supporting surface of the end surface of the pipe wall, but the circular arc-shaped leg of the original T-shaped trigger used as a connector needs to be made smaller.

An eighth embodiment (fig. 35) depicts another shape of a T-shaped trigger that can be used in combination with a U-shaped connector in an interchangeable position, and fig. 35 is a block diagram of such a T-shaped trigger that uses the rolling portion 11 of the upper middle portion of the T-shaped trigger 16 for a convex bearing surface when the T-shaped trigger 16 and the U-shaped connector 13 are combined as shown. If the two parts shown in the figure are interchanged, i.e. the U-shaped connector 13 is used as the U-shaped trigger and the T-shaped trigger 16 is used as the T-shaped hanging connector, the two circular arc-shaped legs of the U-shaped trigger can be used as the rolling parts 11 for the pipe wall end surface supporting surface.

Having described the above summary and embodiments, the combination of the support surface and the trigger and the diversity of the support surface on the end surface of the tube wall will now be described. In the last summarized paragraph of the description of the figures of the fourth embodiment, it has been mentioned that the D-shaped trigger in the D + U solution can have both rolling portions, i.e. the middle portion of its shaft and the arc-shaped foot as the rolling portions, and it can now be said that this obviously means that the lower end of the same tube of the same product can also have both convex supporting surfaces and arc-shaped supporting surfaces of the tube wall end surface supporting surfaces, because the arc-shaped supporting surface is a segment of arc-shaped tube wall end surface of the tube lower end wall end surface, so that the D-shaped trigger in the D + U solution can use the rolling portion in the middle portion of the shaft for the convex supporting surface and the arc-shaped foot rolling portion for the arc-shaped supporting surface in the product, and even can have both convex supporting surfaces and arc-shaped supporting surfaces at the lower end of the tube, The V-shaped supporting surface is also feasible because the two circular arc-shaped feet of the D-shaped trigger piece are used as rolling parts. It is necessary to explain the diversity of the supporting surfaces of the end faces of the pipe wall: since the arc-shaped leg of the trigger is highly applicable when it is used as the rolling portion, particularly when it is used for the tube wall end surface support surface, and more particularly when it is used for the tube wall end surface support surface using only one arc-shaped leg as the rolling portion (fifth embodiment), since the arc-shaped leg can be stably hung as long as there is a little tube wall end surface, that is, it is applicable to various tube wall end surfaces of regular and irregular shapes, and therefore, the shapes of the tube wall end surfaces that can be used are many and are difficult to be defined by all enumeration.

The ninth embodiment (fig. 36) is a mouthpiece support surface: FIG. 36 is a view showing the shape of a nozzle support surface, and from this view, it can be seen that a nozzle support surface 50 of a nozzle at the lower end of a tube 1 has been formed with a plurality of support surfaces such as a convex support surface 17, a concave support surface 4, a V-shaped support surface 20, an arc support surface 51, a straight support surface 52, and the like, and the nozzle support surface is a mixed type support surface and is composed of a flat plate or a branch at the lower end of the tube.

fig. 37 is a schematic diagram showing the first mode, namely, as shown in the figure, a pressure spring sleeve rod 22 sleeved with a pressure spring 27 is hung on an elastic element hanging rod 2 in a pipe 1, a pulling wire 26 can compress the pressure spring, the pulling wire 26 is a hard wire or a soft wire, and the pulling wire 26 is connected with other parts in an inner assembly.

Fig. 38 is a schematic diagram showing a second mode, namely, as shown in the figure, the pressure spring 27 in the pipe 1 is positioned below the spring pressing plate 44 connected with the pulling wire 26, the spring retaining ring 45 is arranged below the pressure spring 27 in the pipe, the pulling wire 26 is a soft wire or a hard wire, the lower end of the pulling wire 26 is connected with other parts in the inner assembly, and the connecting wire or the sub-wire outside the pipe can compress the pressure spring. In the figure 10 is the main line.

Finally, fig. 39 to 48 are schematic views of several different shapes of the rolling part and outline their features of action:

in fig. 39, the rolling part has a cylindrical shape 28.

In fig. 40, the rolling part is also in the shape of a cylinder 28, which differs from the cylinder of fig. 1 only by the fact that the cylinder shown in this figure is shorter.

In fig. 41, the rolling portion is in the form of a large semi-cylinder 29 formed by a straight cut 30 in the cylinder.

In fig. 42, the rolling portion is also in the shape of a large semi-cylinder 29, also formed by a straight cut 30 on the cylinder, differing from the large semi-cylinder of fig. 3 only by the shorter one shown in this figure.

Fig. 43 illustrates the function characteristics of the cylindrical rolling part, which is characterized by high sensitivity, wherein 31 is a pipe wall, the cylindrical rolling part 34 of the trigger 33 is hung on the concave or convex supporting surface 35, and the cylindrical rolling part 34 has certain stability on the concave or convex supporting surface 35 under the static friction force formed by the elastic element acting force 32, but the sensitivity is high.

FIG. 44 is a view showing the operational characteristics of a rolling part having a large semi-cylindrical shape, which is characterized by low sensitivity and is suitable for the heavy bait casting fishing of large fish. In the figure, 31 is a pipe wall, a large semi-cylinder-shaped rolling part 36 formed by a straight cutting surface 30 on a cylinder on a trigger 33 is hung on a concave or convex supporting surface 35, and the sensitivity is low because the straight cutting surface 30 is hung on the concave or convex supporting surface 35.

Fig. 45 shows a curved round bar 37. The function of the rolling part is similar to the characteristics of a cylindrical rolling part when the rolling part is used as the rolling part.

Figure 46 shows the large semicircular bead 39 of the curved bead resulting from the cut surface 38. When the rolling part is used as the rolling part, the action characteristics of the rolling part are similar to those of the rolling part with the shape of a large semi-cylinder.

Fig. 47 is a schematic view showing the action of a circular arc foot without a straight section as a rolling part, in which 31 is a pipe wall, 32 is the acting force of an elastic element, and a circular arc foot rolling part 42 without a straight section of the trigger 33 is hung on a pipe wall end surface supporting surface 41 by the action of a D-shaped ring or an L-shaped hanging connector 40, and the action characteristic is good sensitivity because the circular arc body is in contact with the pipe wall end surface supporting surface 41.

Fig. 48 is a schematic view showing the action of the arc-shaped leg with a straight section on the arc body as the rolling part, in which 31 is the tube wall, 32 is the action force of the elastic element, the arc-shaped leg rolling part 43 with a straight section of the trigger 33 is hung on the tube wall end surface supporting surface 41 by the action of the D-ring or L-shaped hanging connector 40, and the straight section 30 is in contact with the tube wall end surface supporting surface 41, so the tube wall end surface rolling part has the characteristics of strong stability and low sensitivity.
