[0021] The utility model is further described below in conjunction with embodiments.

[0022] See also Figure 1-Figure 4 The cone component 3 includes an upper plate 31 arranged on the outer surface of the valve cover 1, a rod groove 32 opened on the lower surface of the upper plate 31, a middle plate 33 fixedly installed on the lower surface of the rod groove 32, a cone head 34 fixedly installed on the lower surface of the middle plate 33, a through groove 35 penetrating through one side of the cone head 34, and a circular hole 38 opened on the upper surface of the upper plate 31, and the circular hole 38 is connected with the rod groove 32. The cone component 3 can be firmly fixed in the buckle assembly 4 through the cone head 34, and the valve cover 1 and the valve body 2 are also firmly fixed.

[0023] The cone-shaped component 3 further comprises an outer frame 37 fixedly mounted on the inner wall of the circular hole 38 and a pressure assembly 36 movably mounted inside the outer frame 37 . The circular hole 38 allows the outer frame 37 and the pressure assembly 36 to be connected to other structures inside the cone-shaped component 3 .

[0024] A groove 371 is formed on the inner wall of the outer frame 37 , and a reset spring 372 is fixedly installed at the bottom of the groove 371 . The reset spring 372 can reset the pressure assembly 36 .

[0025] The pressure assembly 36 includes an L-shaped plate 361 movably mounted inside the outer frame 37, a button 362 fixedly mounted on the upper surface of the L-shaped plate 361, a torsion shell 363 and a lower pressure plate 364 fixedly mounted on the lower surface of the button 362, and an isolating ball 365 fixedly mounted on the lower surface of the lower pressure plate 364. The L-shaped plate 361 is fixedly connected to one end of the return spring 372, and the top block 45 can be allowed to come out of the through groove 35 through the lower pressure plate 364 and the isolating ball 365.

[0026] A connecting plate 331 is fixedly installed on the inner wall of the middle plate 33 , and a pipe 332 is fixedly installed on one side of the connecting plate 331 , so that the lower pressing plate 364 can only be pressed down along the inside of the pipe 332 through the pipe 332 .

Then, all the required screws can be directly put into the screw holes without taking them one by one. Then, when it is necessary to remove the valve cover 1, it is only necessary to take out the screws first, and then press the button 362. The button 362 will bring the following table The lower pressure plate 364 and the isolating ball 365 are pressed down together, and because the top block 45 is connected to the tension spring 44, the top block 45 will be pushed out of the through groove 35 by the isolation ball 365, and the valve cover 1 can be taken out at this time. Because the reset spring 372 is connected to the L-shaped plate 361, and because of the L-shaped plate 361 and the button 362, when the valve cover 1 is taken out, the button 362 is released, and the lower pressure plate 364 and the isolating ball 365 will be reset. At the same time, the top block 45 will also be reset by the tension spring 44, and return to the state where the two top blocks 45 push against each other, thereby achieving the effect of installing the valve cover 1 without carefully aligning the two threaded holes.
