SUMMARY OF THE INVENTION According to the present invention, a telescopic fishing rod having an adjustable length by providing a telescopic rod portion on a former rod portion has a cylindrical shape on one of the former rod portion and the telescopic rod portion. A fixture having a first engaging portion formed on an inner peripheral portion thereof is provided, and the other end of the former rod portion or the telescopic rod portion is engaged with the first engaging portion. A second engaging portion for restricting movement of the telescopic rod with respect to the original rod is provided.

[0009]

[Action] The main rod portion and the telescopic rod portion are relatively rotated to release the engagement state between the first engagement portion and the second engagement portion of the fixture,
Move the telescopic rod part in the axial direction with respect to the original rod part, and adjust the length of the rod. Then, the original rod portion and the telescopic rod portion are relatively rotated to engage the first engagement portion and the second engagement portion. Thereby, the telescopic rod part can be fixed to the former rod part.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the accompanying drawings. FIG. 1 is an enlarged view of a main part of the telescopic fishing rod according to the present invention. In the figure, reference numeral 1 denotes a former rod.
A fixing member 2 having a cylindrical shape is fixed to the base end side (the right end side in the figure) of. FIG. 2 is a diagram showing the fixture 2. An engagement protrusion 2a, which is a first engagement portion, is integrally provided on an inner peripheral portion of the fixing tool 2 so as to protrude in a centripetal direction. A telescopic rod 3 is provided on the right side of the former rod 1 in the drawing.
It can be stored inside. At a suitable position on the distal end side (left side in the figure) of the telescopic rod 3, a distal end locking member 4 having a shape shown in FIGS. An engagement groove 4a is formed in the distal locking member 4 such that a portion extending in the axial direction and a portion extending in the circumferential direction are bent and communicate with each other. Further, a proximal end locking member 5 having a shape shown in FIGS. 3C and 3D is fixed to the proximal end (right side in the figure) of the telescopic rod 3. An engagement groove 5 a is formed in the proximal locking member 5 such that a portion extending in the axial direction and a portion extending in the circumferential direction are bent to communicate with each other. In addition, on the right side in FIG. 3C, a butt plug 6 (see FIG. 1).

The operation when the telescopic fishing rod thus configured is extended and contracted will be described below. First, when it is desired to extend the fishing rod, the engaging projection 2a of the fixing tool 2 is removed from the axially extending portion of the engaging groove 4a of the distal locking tool 4 fixed to the distal end of the telescopic rod 3 in FIG. The telescopic rod 3 is rotated with respect to the original rod 1 along a portion extending in the circumferential direction. Thereby, the axial movement of the telescopic rod 3 with respect to the main rod 1 is regulated, and the telescopic rod 3 is held in a state of being fixed to the main rod 1.

When the fishing rod is contracted as shown in FIG. 4, the telescopic rod 3 is rotated with respect to the original rod 1 in the state of FIG. Locking device 4
The telescopic rod 3 is moved leftward in FIG. 1 so that most of the telescopic rod 3 is housed in the original rod 1. Then, the engaging projection 2a of the fixing tool 2 fixed to the end of the original rod 1 is engaged from the axially extending portion of the engaging groove 5a of the base end locking tool 5, and further extends in the circumferential direction. The extensible rod 3 is rotated with respect to the original rod 1 along (FIG. 4).
Accordingly, the axial movement of the telescopic rod 3 with respect to the main rod 1 is restricted, and the telescopic rod 3 is held in a state of being fixed to the main rod 1.

FIG. 5 is a view showing another embodiment of the fixture 2 used in the above embodiment.
