DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] The following further describes the present utility model with reference to the drawings.

[0023] As Figures 1 to 8 shown, a knob cover of the knob 1 is provided on the cover plate 2. The rod body of the knob 1 penetrates through the cover plate 2 and is respectively connected to the K-shaped buckle 3 and the lock piece 5; a T-shaped rib 2-2 is provided on the back of the cover plate 2, and the spring piece 4 is clamped outside the T-shaped rib 2-2.

[0024] The knob cover of the knob 1 is an arc-shaped cover plate 1-1 with a long strip protrusion 1-2 connected to one side. The rod body of the knob 1 is provided with a K-shaped buckle groove 1-3 and a locking plate connecting groove 1-4 respectively connected to the K-shaped buckle 3 and the locking plate 5.

[0025] A connection hole 2 - 1 connected to the knob 1 is provided on one side of the cover plate 2 , and T-shaped ribs 2 - 2 are provided on both sides of the connection hole 2 - 1 , and the T-shaped ribs 2 - 2 are located on the back side of the cover plate 2 .

[0026] The T-shaped rib 2 - 2 is an I-shaped structure, and the grooves on both sides of the T-shaped rib 2 - 2 are matched and connected with the spring sheet 4 .

[0027] The K-shaped buckle 3 is in a “C”-shaped structure, and the K-shaped buckle 3 is snap-fitted to the K-shaped buckle groove 1 - 3 of the knob 1 .

[0028] The spring piece 4 is in a "U"-shaped structure, and the middle portion of the spring piece 4 is clamped in the grooves on both sides of the two T-shaped ribs 2-2, with both ends of the spring piece 4 respectively concave inwards.

[0029] The locking plate 5 has a "Z"-shaped sheet structure, and a locking plate connecting hole 5-1 connected to the locking plate connecting groove 1-4 of the knob 1 is provided at one end of the locking plate 5. Rectangular protrusions 5-2 are provided on both sides of the end of the locking plate 5, and the rectangular protrusions 5-2 on both sides are bent inward.

[0030] The operating principle of the present invention is as follows: the knob 1 passes through the connection hole 2-1 of the cover plate 2 and is secured with a K-shaped buckle 3. A spring clip 4 is then inserted through the T-rib 2-2 of the cover plate 2, passing through the T-rib at the head, the rod of the knob 1, and the T-rib at the rear. Because the spring clip 4 is located at the thinnest part of the knob 1, it deforms when twisted, creating resistance. When twisted to a certain angle, the rectangular protrusions 5-2 at each end of the locking plate 5 contact the spring clip 4, achieving the maximum twist angle and opening the cover plate 2. When the hand is released, the spring clip 4 deforms due to its own elastic properties, causing the knob 1 to return to its original position, thus completing the locking action of the cover plate 2.
