Abstract

A gardening fluid connection device contains a body including multiple retainers, a resilient element, and a fitting sleeve including multiple spaced engagement teeth. The resilient element abuts against the body and the fitting sleeve. The body includes a stop rib, and the multiple spaced engagement teeth are pushed by the resilient element to abut against the stop rib. The body includes at least one retaining element, each retaining element is located on a first side of each spaced engagement tooth, and a width of each spaced engagement tooth is equal to a rotation distance of the fitting sleeve, hence the fitting sleeve is rotated reciprocatingly to open or close of the gardening fluid coupling device by using the stop rib, each retaining element, each spaced engagement tooth and the resilient element, and each retaining element is stopped when moving to a second side of each spaced engagement tooth.

First claim

What is claimed is:

1. A gardening fluid connection device comprising: a body on which multiple retainers are retained:
a resilient element; and
a fitting sleeve fitted on a first end of the body, the fitting sleeve including multiple spaced engagement teeth, the resilient element abutting against the body and the fitting sleeve, the fitting sleeve rotating along the body reciprocatingly and pushing the resilient element so as to open or close the gardening fluid coupling device, hence the multiple retainers of the body are removed or retained when the fitting sleeve presses the resilient element or is pushed by the resilient element, respectively, so that the multiple retainers of the body connect with or remove from a water supply device, respectively;
wherein the body further includes at least one retaining element,
wherein the fitting sleeve further includes at least one shoulder respectively located above and contacting with the retaining element so as to maintain the fitting sleeve on a closing position and to make the fitting sleeve unable to press downward when the fitting sleeve rotates to an opening position, the shoulder removing from the retaining element of the body so that the fitting sleeve presses the resilient element to release the multiple retainers and the multiple retainers connect with or remove from the water supply device, and
wherein the body includes a stop rib arranged thereon so that the multiple spaced engagement teeth of the fitting sleeve are pushed by the resilient element to abut against the stop rib of the body, and includes at least one locking element formed on the stop rib and extending toward the spaced engagement teeth, each locking element being located on a side of each spaced engagement tooth and a width of each spaced engagement tooth being equal to a rotation distance of the fitting sleeve.

2. The gardening fluid connection device as claimed in claim 1 ,
wherein the body further includes a surround seat arranged on a middle section thereof, and wherein the fitting sleeve includes a fixing seat formed on a middle section of an inner wall thereof such that the resilient element abuts against the surround seat and the fixing seat.

3. The gardening fluid connection device as claimed in claim 1 , wherein the resilient element is a spring.

4. The gardening fluid connection device as claimed in claim 1 , wherein each retaining element is a protrusion and each shoulder is elongated.
