First, place the components steadily in the installation frame 23. Then, rotate the tongue lock 121 to open the cabinet door 12. The limit bar 24 is separated from the end of the reciprocating rod 230. Then, align the installation frame 23 containing the components with the rectangular groove 2241 on the square rod 224 and directly insert it. Step 2: Correction of component position: Since the component and the mounting frame 23 are combined into a whole, they can be inserted from any position of the rectangular groove 2241, so that the component and the mounting frame 23 can be freely adjusted in the lateral direction. Then, the square rod 224 is manually pulled outward to drive the connecting block 223 and the tapered column 222 to slide outward along the built-in cavity 2211. The outer wall of the circumference of the tapered column 222 slides relative to the arc groove 2251 of the external block 225, and the strong spring 2231 is further compressed. At the same time, the arc grooves 2251 of the two external blocks 225 are stretched. The spring 226 is always in close contact with the outer circumferential wall of the conical column 222 under the tension, and the two are close to each other to drive the tooth plate 227 to disengage from the tooth groove 212. At this time, the limit of the tooth groove 212 on the tooth plate 227 disappears, and then the lifting assembly 22, the installation frame 23 and the components can be freely adjusted in the vertical direction. After the position is determined, the square rod 224 is released to reset the conical column 222, and the external block 225 is pushed again to drive the tooth plate 227 to slide outward, and the tooth groove 212 clamps the tooth plate 227 again, so that the position of the lifting assembly 22, the installation frame 23 and the components is fixed; Step 3: One-time positioning of components: When the positions of all installation frames 23 and components are determined, rotate and close the cabinet door 12, and lock it with the tongue lock 121. During the rotation and closing process of the cabinet door 12, the limit bar 24 is driven to rotate synchronously. When the limit bar 24 contacts the end of the reciprocating rod 230, it begins to push the reciprocating rod 230 inward, and the reciprocating rod 230 squeezes the reset spring 2302 for further compression. At the same time, the reciprocating rod 230 drives the V-shaped connecting rod 2292 to rotate, and the V-shaped connecting rod 2292 drives the push rod 229 to move outward on the inner side of the circular hole 2243, and the push rod drives the locking plate 228 to slide outward in the slide groove 2244 until the locking plate 228 is engaged with the notch on the installation frame 23, so that the vertical plate 21, the lifting assembly 22, several groups of installation frames 23 and several groups of components are combined into a whole at one time.

[0026] Working principle: When in use, first place the component steadily in the installation frame 23, then rotate the tongue lock 121 to open the cabinet door 12, the limit strip 24 is separated from the end of the reciprocating rod 230, and then the installation frame 23 containing the component is aligned with the rectangular groove 2241 on the square rod 224 and directly inserted. Since the component and the installation frame 23 are combined into a whole, they can be inserted from any position of the rectangular groove 2241, and then the component and the installation frame 23 can be freely adjusted in the horizontal direction, and then the square rod 224 is manually pulled outward to drive the connecting block 223 As a result, the conical column 222 slides outward along the built-in cavity 2211, and the outer circumferential wall of the conical column 222 slides relative to the arc groove 2251 of the external block 225, and the strong spring 2231 is further compressed. At the same time, the arc grooves 2251 of the two external blocks 225 are always tightly fitted with the outer circumferential wall of the conical column 222 under the pulling force of the tension spring 226. The two are close to each other and drive the tooth plate 227 to disengage from the tooth groove 212. At this time, the limit of the tooth groove 212 on the tooth plate 227 disappears, and then the lifting assembly 22, the installation frame 23 and The components can be freely adjusted in the vertical direction. After the position is determined, the square rod 224 is loosened to reset the tapered column 222, and the external block 225 is pushed again to drive the tooth plate 227 to slide outward. The tooth groove 212 clamps the tooth plate 227 again to fix the position of the lifting component 22, the installation frame 23 and the components. When the positions of all the installation frames 23 and components are determined, the cabinet door 12 is rotated and closed, and locked with the tongue lock 121. During the rotation and closing process of the cabinet door 12, the limit bar 24 is driven to rotate synchronously. When the limit bar 24 contacts the reciprocating rod 23 0 end, the reciprocating rod 230 begins to be pushed inward, and the reciprocating rod 230 squeezes the reset spring 2302 for further compression. At the same time, the reciprocating rod 230 drives the V-shaped connecting rod 2292 to rotate, and the V-shaped connecting rod 2292 drives the push rod 229 to move outward inside the circular hole 2243, and the push rod drives the locking plate 228 to slide outward in the slide groove 2244 until the locking plate 228 is engaged with the notch on the mounting frame 23, so that the vertical plate 21, the lifting assembly 22, the plurality of mounting frames 23 and the plurality of components are combined into a whole at one time.
