[0026] In the embodiment of the utility model, in order to realize the rapid disassembly and installation of the display screen body 2, specifically, the mounting head 32 is slidably connected with a clamping rod 321, the outer wall of the clamping rod 321 is fixedly connected with one end of a spring 1 322, the other end of the spring 1 322 is fixedly connected to the inner wall of the mounting head 32, the mounting head 32 is rotatably connected with a rotating shaft 324, the outer wall of the rotating shaft 324 is fixedly connected with a rotating block 327, the rotating shaft 324 passes through the cam 323 and is fixedly connected to the cam 323, the inner wall of the mounting head 32 is fixedly connected with a spring 2 325, the top of the spring 2 325 is fixedly connected with a pin block 326, the pin block 326 is slidably connected to the mounting head 32, the rotating block 327 is slidably connected with a pressing block 329, the outer wall of the pressing block 329 is fixedly connected with a spring 328, and the end of the spring 328 away from the pressing block 329 is fixedly connected to the inner wall of the rotating block 327.

[0027] like Figure 4As shown, when the mounting head 32 is inserted into the slot 311, the pressing block 329 is then pressed to make the pressing block 329 slide downward, and at the same time, the spring three 328 is in an elastic deformation state. At this time, the pressing block 329 will squeeze the pin block 326, so that the pin block 326 completely slides into the mounting head 32, thereby releasing the limit of the rotating block 327. At this time, the spring two 325 is in an elastic deformation state, and then the rotating shaft 324 is rotated ninety degrees. When the rotating shaft 324 rotates, the cam 323 fixedly connected to the rotating shaft 324 rotates. In this process, the cam 323 will contact the card rod 321 and squeeze the card rod 321, so that the card rod 321 slides outward until it is inserted into the fixed slot 312 to complete the display screen body. 2 is fixed, at this time, spring one 322 is in an elastic deformation state, when the clamping rod 321 is clamped into the fixing groove 312, then the pressing block 329 is released, at this time, the pin block 326 and the pressing block 329 will slide into the inside of the rotating block 327 under the elastic force of the spring two 325 and the spring three 328, thereby realizing the limiting of the cam 323, when it is necessary to disassemble the display screen body 2, press the pressing block 329, release the limiting of the cam 323 again, and then rotate the cam 323 ninety degrees again, during this process, the pressure of the cam 323 on the clamping rod 321 disappears, at this time, the clamping rod 321 will slide into the inside of the mounting head 32 under the elastic force of the spring one 322 until it is separated from the fixing groove 312, and the limiting of the mounting head 32 can be released.

When the shaft 324 rotates, the cam 323 fixedly connected to the shaft 324 rotates. In this process, the cam 323 contacts the card rod 321 and squeezes the card rod 321, so that the card rod 321 slides outward until it is stuck in the fixed slot 312 to complete the display screen. The main body 2 is fixed, and then the pressing block 329 is released. At this time, the pin block 326 and the pressing block 329 will slide into the inside of the rotating block 327 under the elastic force of the second spring 325 and the third spring 328, thereby limiting the cam 323. When the display body 2 needs to be disassembled, the pressing block 329 is pressed to release the limit of the cam 323 again, and then the cam 323 is rotated ninety degrees again. During this process, the pressure of the cam 323 on the clamping rod 321 disappears. At this time, the clamping rod 321 will slide into the inside of the mounting head 32 under the elastic force of the spring one 322 until it is disengaged from the fixing groove 312, and the limit of the mounting head 32 can be released.
