The elastic cushion 6 is U-shaped, the side walls of the two sides of the elastic cushion are different in length, and one side of the bottom wall of the elastic cushion is fixedly plugged into the avoiding groove 314 and does not collide with the fixing part; the longer side wall of the handle extends into the rotating groove 3111 to be matched with the groove wall of the rotating groove 3111 to be tightly attached to the side wall of the rotating shaft 221, so that no rotating gap exists between the rotating shaft 221 and the ball head connecting part 31, an imaginary position which cannot be directly driven to the rotating shaft 221 exists when the handle 3 rotates is avoided, and the rotating hand feeling is better; the elastic pad 6 has elasticity, and therefore, the presence of the elastic pad 6 does not restrict the rotation of the rotation shaft 221 with respect to the ball joint portion 31.

In this embodiment, the ball head connecting portion 31 has a plane 312, and the plane 312 is flush with the opening end of the body 1 when the valve element 2 is in the closed state, so that the end of the body 1 is flat, the material is saved, and the visual aesthetic feeling is improved.

The shower faucet that this embodiment provided, handle 3 stirs case 2 with the help of ball head connecting portion 31's rotation and opens and close, not only reduced handle 3 operation portion 32 effectively and need pivoted stroke and scope, accomplish holding in order to promote the wholeness of body 1 appearance with the great degree of the rotating part of handle 3, the fineness and the pleasing to the eye degree, and the ball head connecting portion 31 of handle 3 is simple in the mounting structure on body 1, can realize quick assembly disassembly, furthermore, the seam of body 1 outer wall and handle 3 is little, be difficult for hiding dirty dirt, clean convenient and can not influence handle 3's operation and feel.

During actual assembly, the valve core 2 is fixed in place in the body 1 by a locking nut, then the first limiting sleeve 4 is sleeved in the body 1, the abdicating notch 42 and the clamping protrusion 11 are aligned during the sleeving so as to ensure that the clamping groove 41 on the first limiting sleeve 4 can be positioned on the same circumference with the clamping protrusion 11 when the first limiting sleeve 4 enters in place in the body 1, when the first limiting sleeve 4 is abutted against the clamping protrusion 11 and cannot enter the inner side of the body 1 continuously, the first limiting sleeve 4 is rotated by 90 degrees, the clamping protrusion 11 and the clamping groove 41 form clamping, and the first limiting sleeve 4 is assembled; the ball head connecting part 31 is arranged in the body 1, the threaded hole 313 on the ball head connecting part is adjusted to the second rotation stopping groove 13 on the side wall of the body 1, and then the second limiting sleeve 5 is plugged into the body 1 to be clamped in place under the condition that the second rotation stopping protrusion 53 is aligned with the second rotation stopping groove 13; finally, the operation part 32 is screwed on the ball head connecting part 31, and the assembly is completed; when disassembling, the disassembling is carried out according to the steps opposite to the assembling steps.

The description of the above specification and examples is intended to illustrate the scope of the invention, but should not be construed as limiting the scope of the invention.
