The second movable rod 141 is slidably installed on the mounting seat 11. The second movable rod 141 consists of a round rod part that can slide back and forth and a hand-held part extending to the left. A second wedge block 142 is welded to the end of the second movable rod 141. The second wedge block 142 can be inserted into the card seat 10 for fixation. A second elastic member 143 is connected between the second wedge block 142 and the mounting seat 11. The second wedge block 142 remains in an inserted state under the action of the second elastic member 143. The second elastic member 143 is made of a stainless steel compression spring.
[0035] When the position of the components fixed on the mounting seat 11 needs to be adjusted, the second movable rod 141 is pulled to the middle position, the second elastic member 143 is compressed, and the second wedge block 142 is pulled outward and completely separated from the socket on the inner side of the card seat 10. At this time, the mounting seat 11 can be moved left and right to a suitable position, and the distance between each mounting seat 11 can be adjusted, or the side door 3 can be directly opened to move the mounting seat 11 along the direction of the card seat 10 to remove it, and the components on the mounting seat 11 can be checked and replaced. After the replacement is completed, it is put back between the card seats 10, and the second movable rod 141 is released. The second movable rod 141 moves forward and backward under the resetting action of the second elastic member 143, and the second wedge block 142 is reinserted into the socket on the card strip 7 and fixed.
[0036] Example 3
[0037] On the basis of Example 2, Figure 6 and Figure 7As shown, the buckle structure 12 includes a boss 121, a cylindrical boss 121 is provided on the rear side of the fixed plate 8, and a groove 122 that cooperates with the boss 121 is opened on the rear door 4. The buckle structure 12 also includes a trigger block 123, a pressure block 125, a slider 126, a third elastic member 127 and a fourth elastic member 128. The trigger block 123 is sleeved on the first movable rod 131 of the fixed plate 8, and the trigger block 123 extends and protrudes in the rear direction. The trigger block 123 can slide relative to the fixed plate 8, and a T-slot 124 is opened on the rear door 4. The T-slot 124 is longer in the horizontal direction and shorter in the vertical direction. A pressure block 125 and a slider 126 are slidably installed in the T-slot 124, and the pressure block 125 can move forward and backward relative to the rear door 4. Sliding, a third elastic member 127 is connected between the pressure block 125 and the rear door 4, and the third elastic member 127 is made of a stainless steel compression spring. Under the action of the third elastic member 127, the pressure block 125 extends forward to limit the sliding of the slider 126. The slider 126 can slide left and right relative to the rear door 4. A fourth elastic member 128 is connected between the slider 126 and the rear door 4, and the fourth elastic member 128 is made of a stainless steel compression spring. Under the action of the fourth elastic member 128, the slider 126 maintains a trend of moving inward. When the boss 121 on the fixed plate 8 extends into the groove 122 of the rear door 4, the trigger block 123 presses down the pressure block 125, and the slider 126 drives the trigger block 123 to move inward, thereby driving the fixed plate 8 and the card strip 5 to disengage.
[0038] When the fixing plate 8 needs to be connected to the rear door 4, the fixing plate 8 is controlled to move backward until the boss 121 is fully extended into the groove 122 on the rear door 4. During the movement, the trigger block 123 gradually presses the pressure block 125 backward into the end of the T-slot 124. The third elastic member 127 is compressed, and the pressure block 125 no longer blocks the slider 126 from sliding left and right. The slider 126 pushes the trigger block 123 inward under the resetting action of the fourth elastic member 128. The trigger block 123 drives the first movable rod 131 to move inward synchronously, so that the first wedge block 132 is disengaged from the card strip 7. The slider 126 presses the trigger block 123 tightly and fixes it in the T-slot 124 of the rear door 4, and the fixing plate 8 is fixed to the rear door 4.

The card block 152 is slidably installed on the rear door 4, and the card block 152 can slide left and right relative to the rear door 4. A fifth elastic member 153 is connected between the card block 152 and the rear door 4. The fifth elastic member 153 is connected between the card block 152 and the rear door 4. The sexual component 153 is made of a stainless steel compression spring. A U-shaped guide tube 154 is provided on the rear door 4. A pull rope 155 is slidably installed in the guide tube 154. The pull rope 155 can move along the guide tube 154. One end of the pull rope 155 is connected to the block 152, and the other end is connected to the pulley 156. The rotation of the pulley 156 can drive the pull rope 155 to tighten the block 152 and disengage the boss 121. The pulley 156 is coaxially connected to the knob 157. A torsion spring 158 is connected between the pulley 156 and the rear door 4.
[0040] When the fixing plate 8 is fixedly connected to the rear door 4, the block 152 extends into the slot 151 on the side of the boss 121 under the action of the fifth elastic member 153, limiting the movement of the boss 121 in the front-rear direction, further strengthening the connection between the fixing plate 8 and the rear door 4. When the fixing plate 8 needs to be removed from the rear door 4, the knob 157 is first rotated to drive the pulley 156 to rotate, and the pull rope 155 moves in the guide tube 154 toward the pulley 156 and is tightened, so that the block 152 is pulled outward, and the fifth elastic member 153 is pressed against the pulley 156. 153 is compressed by force, and the blocking block 152 is disengaged from the boss 121. Then, the position of the first movable rod 131 is adjusted so that the trigger block 123 is no longer restricted, and the fixing plate 8 can be removed as a whole and separated from the rear door 4. At this time, the knob 157 is loosened, and the pulley 156 rotates in the opposite direction under the reset action of the torsion spring 158. The blocking block 152 is re-popped out and protrudes toward the inside of the groove 122 under the reset action of the fifth elastic member 153, and the pull rope 155 moves along the guide tube 154 away from the pulley 156 to return to its initial state.
