Abstract

A stand bar lengthening device comprises a connection sleeve and a lengthened rod, wherein an upper portion port of the connection sleeve is a conical face, three cut grooves are evenly arranged at the circumference of the conical face, guide pieces with the conicity identical with the conical face are installed in the cut grooves, an internal thread is positioned in a lower portion port of the connection sleeve, the lower portion port is connected with the lengthened rod with an external thread, and a rubber pad is adhered to the bottom of the lengthened rod. The stand bar lengthening device can be sleeved on a table foot through the connection sleeve and fixed through the guide pieces in the cut grooves, and the lower portion of the connection sleeve is connected with the lengthened rod to lengthen the table foot. The connection sleeve is in thread connection with the lengthened rod, so that the length of the lengthened table foot can be adjusted slightly.

Description

A kind of leg length extension device
Technical field
