Abstract

A kind of relay baton, to include in first pipe, first in pipe, second to hold a writing brush or pen-write and second to hold a writing brush or pen-write, described first holds a writing brush or pen-write and second holds a writing brush or pen-write in hollow structure, and in described first, the end of pipe is positioned at described first and holds a writing brush or pen-write, and in described second, the end of pipe is positioned at described second and holds a writing brush or pen-write; Be provided with the first spring in described first cavity held a writing brush or pen-write, one end of described first spring is connected with the first inner wall at end held a writing brush or pen-write, and the other end is connected with the end of pipe in described first; In described first, the end of pipe is provided with step, and described first initiating terminal held a writing brush or pen-write is provided with projection, and described projection is blocked spacing with described step mutually; In described first, the initiating terminal of pipe is connected with the initiating terminal of pipe in second.When the present invention person of seesawing joins, relay baton can stressed stretcher strain, and the sliding rod of difficult drop-off, effectively improves and compare achievement.

Description

Relay baton

Technical field

The present invention relates to a kind of relay baton of sports.

Background technology

Conventional relay baton, just a barred body, size is fixing, easily occurs sliding excellent phenomenon, affect games results when the person of seesawing joins.

Summary of the invention

The present invention mainly solves the deficiency of above-mentioned relay baton, provides a kind of relay baton of elastic construction, and when the person of seesawing joins, relay baton can stretch, and the sliding rod of difficult drop-off, effectively improves and compare achievement.

The present invention solves the problems of the technologies described above adopted technical scheme:

A kind of relay baton, to include in first pipe, first in pipe, second to hold a writing brush or pen-write and second to hold a writing brush or pen-write, described first holds a writing brush or pen-write and second holds a writing brush or pen-write in hollow structure, and in described first, the end of pipe is positioned at described first and holds a writing brush or pen-write, and in described second, the end of pipe is positioned at described second and holds a writing brush or pen-write; Be provided with the first spring in described first cavity held a writing brush or pen-write, one end of described first spring is connected with the first inner wall at end held a writing brush or pen-write, and the other end is connected with the end of pipe in described first; In described first, the end of pipe is provided with step, and described first initiating terminal held a writing brush or pen-write is provided with projection, and described projection is blocked spacing with described step mutually; Be provided with the second spring in described second cavity held a writing brush or pen-write, one end of described second spring is connected with the second inner wall at end held a writing brush or pen-write, and the other end is connected with the end of pipe in described second; In described second, the end of pipe is provided with step, and described second initiating terminal held a writing brush or pen-write is provided with projection, and described projection is blocked spacing with described step mutually; In described first, the initiating terminal of pipe is connected with the initiating terminal of pipe in second.

Described first and second holds a writing brush or pen-write and includes hollow tube and end cap, and described end cap is arranged on the end of described hollow tube.

Described first and second holds a writing brush or pen-write and is provided with Anti-slip cover.

In described first, pipe manages detachable connection with in second.

Operation principle of the present invention: by interior pipe and the spring action between holding a writing brush or pen-write, flexible adjustment overall dimensions, can stretch under stressing conditions, when avoiding handing-over, relay baton comes off sliding rod.

Beneficial effect of the present invention is: when the person of seesawing joins, relay baton can stressed stretcher strain, and the sliding rod of difficult drop-off, effectively improves and compare achievement; Due to spring action, the conventional sense of relay baton draws in, convenient gripping, and have protruding spacing with the card mutually of step, and preventing from holding a writing brush or pen-write stretching swings; The surface that holds a writing brush or pen-write is provided with protective jacket, grips more firm; Structure is simple, and result of use is good.
