Portable self-adaptive telescopic martial art training stick

Abstract

The invention belongs to the technical field of martial art training equipment and particularly relates to a portable self-adaptive telescopic martial art training stick. The training stick comprises a plurality of main sticks, wherein every two adjacent main sticks are connected through a telescopic stick, when the training sticks retract, every two main sticks are connected through a separable connecting device, when the training sticks stretch, every two main sticks are connected through a telescopic stick, and the separable connecting devices are connected with the telescopic sticks; the telescopic stick comprises a connecting rod, an air spring, a connecting plate capable of being bent into an arc shape, a connecting layer and a deformable buffering body. When the training stick is in a contracted state, the telescopic stick is located in a cavity formed by the main stick and the air spring is compressed, when the training stick is in an extended state, the telescopic stick is exposed, the air spring automatically extends, the connecting plate, the connecting layer and the deformable buffer body extend in a self-adaptive mode, an operator only needs to control the position of the main stick, self-adaptive deformation of the telescopic stick can be achieved, and operation is convenient and fast; and the requirement on the operator is low.

Description

technical field [0001] The invention belongs to the technical field of martial arts training equipment, in particular to a portable self-adaptive telescopic martial arts training stick. Background technique [0002] Martial arts training sticks are also called "sticks". In ancient times, sticks were often called "stiles". Although they have different names, they are actually one thing. The stick is a weapon without a blade, known as "the leader of a hundred soldiers". A striking weapon in Chinese martial arts. The stick has a long history and is one of the main production tools in primitive society and one of the earliest weapons used in war. The length is about 1.3-2.6 meters, and some are as long as 4 meters. The cross-section is generally circular, and the thickness can be grasped with one hand. The stick is a weapon for melee combat, and its attack range is larger than that of knives and guns. Since ancient times, there has been a saying that "sticks sweep a large are...

AI Technical Summary

Problems solved by technology

Since the outer perimeter of the contracted telescopic stick is smaller than the inner perimeter of the main stick, and the adjacent arc-shaped plates are in rigid contact, the adjacent arc-shaped plates cannot shrink the same distance, and the operation of moving the telescopic stick only to the direction of the main stick cannot be guaranteed This kind of demand requires manpower to press a part of the arc-shaped plate to make it shrink first, and then put the entire telescopic stick into the main stick. However, it requires a strong finger pressure to control the contraction of the arc-shaped plates at different positions at the same time by manpower. High requirements for operators, resulting in inconvenient use and time-consuming retraction of martial arts sticks
