Therefore, the universal joint assembly 100 according to the embodiment of the present invention can cover the gap between the main body 110 and the mounting seat 120 with the protective cover 140. The gap provides an operation space for the user to assemble and disassemble the universal joint assembly 100, and the protection cover 140 is additionally arranged in the operation space, so that the safety and the stability of the whole component in the using process can be improved. Therefore, when the user uses the universal joint assembly 100, the universal joint 130 and the main body 110 are prevented from loosening or even falling off due to misoperation of the mounting base 120, and safety is improved. In addition, the protection cover 140 can also be used as a decoration cover, so that the appearance of the whole component is more attractive.

Illustratively, the holder body 121 may be screwed or screwed with the body 110. The connection between the seat body 121 and the main body 110 is in a threaded connection or a screwing connection mode, so that the seat body 121 and the main body 110 are relatively fixed and cannot move relatively, the stability of the overall structure of the universal joint assembly 100 is improved, and in addition, the connection mode is simple in structure and easy to realize.

For example, an outer side wall of the holder body 121 may be provided with an external thread. A first annular wall 111 may be provided on the body 110 and within the recess 114. The first annular wall 111 may be internally threaded on an inner side thereof. The external thread may be connected with the internal thread. Typically, a seal is disposed between the seat body 121 and the rotatable ball 131. Damping force can be generated between the sealing element and the rotatable ball head 131, so that the rotatable ball head 131 can stay at any angle, and the use is convenient for users. Referring to fig. 5-6, in the universal joint assembly 100 with this arrangement, the sealing element can be installed between the seat body 121 and the rotatable ball 131 first, and the external thread on the outer sidewall of the seat body 121 does not affect the installation of the sealing element. The user can screw the holder body 121 with the rotatable ball 131 directly onto the internal thread on the inner side of the first annular wall 111 to achieve a quick connection. And if conversely, what set up on the lateral wall of pedestal 121 is the internal thread, and sets up the external screw thread on the first rampart 111, just need reserve the space during the installation between the internal thread that sets up on the lateral wall of sealing member and pedestal 121, lets first rampart 111 can insert, can make the installation very loaded down with trivial details trouble of doing so. The outer side wall of the seat body 121 is provided with an external thread, and the inner side surface of the first annular wall 111 is provided with an internal thread, so that the universal joint assembly 100 can be mounted more conveniently and simply, and the implementation is facilitated.

A first seal 150 may be interposed between the inner sidewall 1143 of the mounting through-hole 1211 and the rotatable ball 131. The spacing flange 1213 may be annular, toothed or in a variety of other forms. The retaining flange 1213 may have an interference fit with the rotatable ball 131 to retain the rotatable ball 131 within the mounting through-hole 1211. Obviously, the form of the limiting flange 1213 limiting the rotatable ball 131 in the mounting through hole 1211 can be various, and the interference fit is only one of them and is not particularly limited. The first seal 150 may be a spherical seal, a cylindrical seal, or various other types. After the rotatable ball 131 is limited in the installation through hole 1211, the first sealing element 150 can improve the damping force between the rotatable ball 131 and the seat body 121, so that the rotatable ball 131 can be stopped at any position in the seat body 121, and the use requirement of the user can be met.
