Description

Technical Field

[0001] The present application relates to the field of rotary tools, and in particular to a labor-saving tool. Background Art

[0002] Faucet water purifier refers to a miniature water purification device / equipment that is directly installed and hung on the household faucet. The faucet water purifier has an immediate effect on improving water quality, and its installation and maintenance procedures are simple and convenient. The faucet water purifier is generally threaded with a connecting tube for connecting to the faucet, and the connecting tube is generally threaded with the faucet water purifier.

[0003] refer to Figure 1 The connecting tube 1 includes an integrally formed annular tube 11 and a threaded tube 12. The outer wall of the annular tube 11 is provided with a plurality of outer flanges 13 and outer grooves 14. An inner flange 15 and an inner groove 16 are formed inside. The inner wall of the annular tube 11 is also fixedly provided with a center ring. In the process of rotating the connecting channel, the outer flange 13 and the outer groove 14 increase the friction between the connecting tube 1 and the hand. There is also a strip groove on the connecting tube 1. By inserting a coin or other tool into the strip groove, the connecting tube 1 can be rotated by rotating the coin.

[0004] With respect to the above-mentioned related technologies, the inventors believe that the following defects exist: although the flange and the groove can increase the friction between the connecting tube 1 and the hand, when the connection between the connecting tube 1 and the faucet water purifier is very firm or when the outer wall of the connecting tube 1 is worn during long-term use, it will also be very laborious to rotate the connecting tube 1; although inserting a coin or other tool into the bar groove of the connecting tube 1 and rotating the coin to rotate the connecting tube 1 has a labor-saving effect, during the rotation process, the coin will still have relative movement with the connecting tube 1, making it inconvenient to rotate the connecting tube 1.
