Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

Examples

As shown in fig. 1-2, the universal sleeve disclosed by the present invention comprises a sleeve 1, a fixing plate 2 and a clamping column 3, wherein a quadrilateral groove 11 is formed on an end surface of one side of the sleeve 1, an accommodating cavity 12 is formed on an end of the sleeve 1 away from the groove 11, the fixing plate 2 is disposed in the accommodating cavity 12 and is located at an end of the accommodating cavity 12 close to the groove 11, first through holes 21 are uniformly formed on the fixing plate 2, the clamping column 3 passes through the first through holes 21 to be slidably connected with the fixing plate 2, a first bump 31 and a second bump 32 are fixedly connected to a side wall of the clamping column 3, the first bump 31 is in contact with an end surface of the fixing plate 2 close to the groove 11, a return spring 33 is sleeved on the clamping column 3, one end of the return spring 33 is in contact with an end surface of the fixing plate 2 away from the first bump 31, the other end of the second protrusion contacts with the end face of the second protrusion 32, and the end of the clip column 3 far away from the first protrusion 31 protrudes out of the end face of the sleeve 1.
