A spring 7 is arranged in the inner tube 5, the head of the spring 7 is abutted against a spring fixing plate arranged in the inner tube 5, and the spring fixing plate is close to the head of the inner tube 5. The tail part of the spring 7 is propped against a second spring fixing plate arranged in the outer tube 6, and the second spring fixing plate is close to the tail part of the outer tube 6. When the baton is in a retraction state, the inner tube 5 is retracted in the outer tube 6, and the spring 7 is compressed by the inner tube 5; when the baton is in the extended state, the inner tube 5 is extended out of the outer tube 6 and the spring 7 is restored or stretched by the inner tube 5.
The inner pipe 5 comprises an inner pipe body, an inner pipe head metal joint 1 and an inner pipe tail metal joint 8, wherein the inner pipe head metal joint 1 and the inner pipe tail metal joint 8 are respectively arranged at the head end and the tail end of the inner pipe body. When the inner pipe body is manufactured, the carbon fibers are woven into the preformed body, and then the resin matrix is injected to form the inner pipe body. The metal joint 1 at the head part of the inner pipe and the metal joint 8 at the tail part of the inner pipe are fixed together with the inner pipe body through strong glue. The inner tube body is made of the carbon fiber composite material, so that the mass of the baton is reduced, and the overall strength is improved.
The outer tube 6 comprises an outer tube body, and outer tube head metal joints 2 and outer tube tail metal joints 9 which are respectively arranged at the head end and the tail end of the outer tube body. When the outer tube body is manufactured, the carbon fibers are woven into the preformed body, and then the resin matrix is injected to form the outer tube body. The metal joint 2 at the head part of the outer pipe and the metal joint 9 at the tail part of the outer pipe are fixed together with the outer pipe body through strong glue. The invention makes the outer tube body into the carbon fiber composite material, thereby reducing the mass of the baton and increasing the overall strength.
The inner pipe 5 and the outer pipe 6 are externally sleeved with connecting structures. When the baton is in a withdrawing state, the inner tube 5 is withdrawn to the inner tube head metal joint 1 and is positioned in the outer tube head metal joint 2, and the outer tube head metal joint 2 and the inner tube head metal joint 1 are mutually locked through a connecting structure; when the baton is in the extension state, the inner tube 5 extends to the inner tube tail metal joint 8 and is positioned in the outer tube head metal joint 2, and the outer tube head metal joint 2 and the inner tube tail metal joint 8 are mutually locked through the connecting structure.
The connecting structure comprises a telescopic sleeve 4 sleeved outside the metal joint 2 at the head part of the outer pipe, and a circle of outer arc-shaped groove is formed in the inner wall of the telescopic sleeve 4. At least 3 limiting holes 3 are formed along the circumferential direction of the metal joint 2 at the head of the outer pipe, and a steel ball 11 is arranged in each limiting hole 3. The outer circumferential surfaces of the metal joint 1 at the head part of the inner pipe and the metal joint 8 at the tail part of the inner pipe are respectively provided with a circle of inner arc-shaped grooves. When the baton is in a withdrawing state, the steel ball 11 part which is retracted into the limiting hole 3 in the inner tube 5 falls into the inner arc-shaped groove of the inner tube head metal joint 1, so that the inner tube head metal joint 1 and the outer tube head metal joint 2 are mutually locked. When the baton is in an extension state, the steel balls 11 which extend into the limiting holes 3 of the inner tube 5 partially fall into the inner arc-shaped groove of the inner tube tail metal joint 8, so that the inner tube tail metal joint 8 and the outer tube head metal joint 2 are mutually locked.
When the baton changes from the withdrawing state to the extending state or from the extending state to the withdrawing state, the steel balls 11 in the limiting holes 3 are separated from the inner arc-shaped grooves, and the lower parts of the steel balls 11 pushed by the inner tube 5 are positioned in the outer arc-shaped grooves, so that the inner tube 5 can freely move relative to the outer tube 6.
