Abstract

The utility model discloses a relay baton, comprising a first inner tube, a second inner tube, a first grip tube and a second grip tube, wherein the first grip tube and the second grip tube are in hollow structures, the tail end of the first inner tube is positioned in the first grip tube, and the tail end of the second inner tube is positioned in the second grip tube; a first spring is arranged in the hollow cavity of the first grip tube, one end of the first spring is connected with the inner wall of the tail end of the first grip tube, and the other end of the first spring is connected with the tail end of the first inner tube; a step is arranged at the tail end of the first inner tube, a bulge is arranged at the beginning end of the first grip tube, and the bulge and the step are clamped to realize the limiting effect; and the beginning end of the first inner tube is connected with the beginning end of the second inner tube. The relay baton can be stretched and deformed when being passed on to the next athlete from the former athlete, and cannot be easily dropped due to smoothness, so that the competition result is effectively improved.

Description

Relay baton

Technical field

The utility model relates to the relay baton that a kind of sports is used.

Background technology

Conventional relay baton is a barred body, and size is fixed, and occurs sliding excellent phenomenon during the person of seesawing handing-over easily, influences games results.

Summary of the invention

The utility model mainly is the deficiency that solves above-mentioned relay baton, and a kind of relay baton of elastic construction is provided, and relay baton can stretch during the person of seesawing handing-over, and the sliding rod of difficult drop-off effectively improves relatively achievement.

The utility model solves the problems of the technologies described above the technical scheme that adopts:

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

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

Described first and second holds a writing brush or pen-write and is provided with anti-sliding sleeve.

The detachable connection of pipe in the pipe and second in described first.

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

The beneficial effects of the utility model are: the person of seesawing when handing-over relay baton can stressed stretcher strain, and the sliding rod of difficult drop-off effectively improves relatively achievement; Because spring action, the conventional state of relay baton draws in, the convenient gripping, and have projection spacing with the card mutually of step, the swing that stretches prevents from holding a writing brush or pen-write; The surface that holds a writing brush or pen-write is provided with protective jacket, grips more firm; Simple in structure, result of use is good.
