[0030] It can be further explained that, through the setting of the clamping block 402 and the clamping slot 201, the shell 2 and the cover plate 3 are conveniently connected and fixed initially, and the clamping block 402 can move horizontally and drive the limit block 407 to rotate through mechanical transmission, so as to facilitate the engagement and fixation of the limit block 407 and the support block 202, thereby performing a secondary connection and fixation on the initially connected shell 2 and the cover plate 3, thereby improving the connection strength between the shell 2 and the cover plate 3, and compared with the traditional method of fixing by bolts, the connection and disassembly efficiency of the shell 2 and the cover plate 3 is improved, thereby improving the user's maintenance efficiency of the mechanical parts inside the shell 2.

[0031] See also Figure 3 and Figure 5 The connecting mechanism 4 also includes a push rod 401 fixed to the top of the block 402 by bolts, the push rod 401 extends to the top of the cover plate 3, and a through groove 301 is provided on the top of the cover plate 3. The through groove 301 matches the moving trajectory of the push rod 401. The horizontal movement of the push rod 401 can drive the block 402 to move, thereby facilitating the block 402 to be stored inside the cover plate 3; a card slot 201 is provided on the inner wall of the shell 2, the card slot 201 matches the card block 402, and a support block 202 is fixed to the inner wall of the shell 2 by bolts, and the support block 202 is located below the card slot 201. The support block 202 is used to limit The card block 402 is engaged with the support cover plate 3 and the card slot 201 by language; the inner wall of the push rod 401 is sleeved with a limiting column 4011, and the two ends of the limiting column 4011 are fixedly connected to the inner wall of the through slot 301 by bolts, the limiting column 4011 is used to support the push rod 401 and the card block 402, and the limiting column 4011 is used to ensure the stability of the push rod 401 and the card block 402 during horizontal movement; one end of the card block 402 is fixedly connected to a spring body 403, and the other end of the spring body 403 is fixedly connected to the inner wall of the cover plate 3, and the spring body 403 is used to provide a reset force for horizontal movement to the card block 402.

[0032] It can be further explained that the movement of the push rod 401 drives the block 402 to move, and the block 402 moves to the inside of the cover 3. At this time, the spring body 403 is squeezed by force, and the cover 3 is moved downward to the top of the support block 202. Then the push rod 401 is released, the spring body 403 returns to its original state and drives the block 402 to return to its original state. The block 402 returns to its original state and moves to the inside of the slot 201. At this time, the cover 3 is initially connected to the shell 2.

At this time, the cover plate 3 is preliminarily connected with the housing 2;

[0036] Secondly, when the block 402 moves toward the spring body 403, the block 402 moves and drives the first spur gear 404 to rotate clockwise, the first spur gear 404 rotates and drives the second spur gear 405 to rotate counterclockwise, the second spur gear 405 rotates and drives the second connecting column 406 to rotate, the second connecting column 406 rotates and drives the limit block 407 to rotate counterclockwise, the limit block 407 rotates counterclockwise and moves to the inside of the storage groove 302, when the block 402 and the slot 201 are at the same horizontal position, the push rod 401 resets and moves and drives the limit block 407 to reset and rotate through mechanical transmission, the limit block 407 resets and rotates and squeezes the bottom end of the support block 202, and the cover plate 3 is connected to the housing 2 again.

[0037] Finally, by setting the clamping block 402 and the clamping slot 201, it is convenient to initially connect and fix the outer shell 2 and the cover plate 3, and the clamping block 402 can move horizontally and drive the limit block 407 to rotate through mechanical transmission, so as to facilitate the engagement and fixation of the limit block 407 and the support block 202, thereby performing a secondary connection and fixation on the initially connected outer shell 2 and the cover plate 3, thereby improving the connection strength between the outer shell 2 and the cover plate 3, and compared with the traditional method of fixing by bolts, the connection and disassembly efficiency of the outer shell 2 and the cover plate 3 is improved, thereby improving the user's maintenance efficiency of the mechanical parts inside the outer shell 2.
