Description

Torque sleeve connection device

technical field

The invention relates to a torsion sleeve connection device, in detail, it is an extension device with a torsion escape effect.

Background technique

At present, the DIY trend of people to decorate their homes by themselves is becoming more and more popular. In addition, the development of domestic hand tools has reached a certain level. It is unanimously affirmed that in the past few years, in order to make it easier for the general consumer to use, various hand tools that are easy to operate or have humanized functions have been introduced to the market.

Due to the different locations of the locks, screws of various sizes come out, and to pull the screws of various sizes, corresponding sockets of various sizes are required. , or by means of power tools such as electricity, wind, combustion, etc., most of them can be used with various sockets to improve their scope of application;

In general, the specification change of the sleeve is mainly due to the inner diameter of the sleeve mouth, and the overall length of the sleeve does not have much difference. When the barrel is used, a connecting device is needed to assist, and if the connecting device can provide functions other than the extension length, its practicality can be increased;

Such as the "transmission member that can control the torque" of Taiwan Patent Application No. 094220066, its body has a certain length, and has the most basic extension function, and the upper and lower sections of the body are in a locked state, and the lower section can be driven by turning the lower section. The internal elastic part changes the torsion trip value that the upper section can withstand, so as to provide the effect of torsion trip;

However, the lower part of the conventional previous case controls the torque tripping value by means of rotation, but a set of connecting holes is provided at the tail of the lower part, and the connecting holes are used as sets of objects such as wrench tools and power tools.
