[0027] Specifically, a first moving groove for sliding and inserting the moving block 61 is formed inside the mounting frame 3. A first vertical groove for inserting the connecting rod 63 is formed at the top end of the inner wall of the first moving groove. The length of the moving block 61 is 0.6 times the length of the first moving groove. A locking hole is formed on one side of the first moving groove. The locking member 7 includes an insertion block 71, and the insertion block 71 is inserted into the locking hole. A through groove is formed on one side of the first moving groove. A拨动条64 for moving the moving block 61 is fixedly connected to one side of the moving block 61, and the拨动条64 is inserted into the through groove. A second vertical groove is formed at the bottom end of the guard plate 5, and the top of the connecting rod 63 is inserted into the second vertical groove.

A limiting rod 8 is fixedly connected to the top end of the mounting frame 3, and an insertion groove for inserting the limiting rod 8 is formed at the bottom end of the guard plate 5.

[0028] Furthermore, the moving block 61, the plug-in block 62 and the connecting rod 63 are produced by an integral casting method. The moving block 61, the plug-in block 62 and the connecting rod 63 are composed of two parts combined, so as to facilitate the installation of the locking member 7. Two sets of connection components 6 are provided, which are symmetrically arranged on both sides of the top of the mounting frame 3 respectively. The number of the first moving groove, the first vertical groove, the through groove, the second vertical groove and the second moving groove is the same as that of the connection component 6, and the positions where they are formed correspond to the positions of the connection component 6. The moving block 61, the plug-in block 62 and the connecting rod 63 form a C shape. The拨动条64 is fixedly connected to one side of the moving block 61 by an adhesive method. The length of the through groove corresponds to the length of the first vertical groove. The first vertical groove, the second vertical groove, the first moving groove and the second moving groove form a C shape. The heights of the first moving groove and the second moving groove respectively correspond to the heights of the moving block 61 and the plug-in block 62. The lengths of the first vertical groove and the second vertical groove are the same, both being 1.01 times the length of the plug-in block 62. The bottom end of the limiting rod 8 is fixedly welded to the top end of the mounting frame 3. The size of the insertion groove is 1.01 times the size of the limiting rod 8.

Under the action of the limiting rod 8 and the insertion groove, the guard plate 5 cannot move horizontally. By moving the拨动条64, the拨动条64 drives the moving block 61, the moving block 61 drives the connecting rod 63, and the connecting rod 63 drives the plug-in block 62, so that the plug-in block 62 and the moving block 61 are respectively inserted into the second moving groove and the first moving groove, thereby realizing the fixed connection between the guard plate 5 and the mounting frame 3.

[0029] It should be noted that there is an undefined term "拨动条64" in the original text. You may need to clarify or correct this term for a more accurate translation.Specifically, a cavity for installing the plug block 71 is opened inside one end of the moving block 61, a through hole for inserting the plug block 71 is opened on one side of the inner wall of the cavity, a baffle 72 for limiting the movement of the plug block 71 is fixedly connected to one end of the plug block 71, and an elastic block 73 for pushing the baffle 72 is provided on one side of the baffle 72.

[0030] Furthermore, the locking member 7 is used to limit the movement of the moving block 61 in the first moving groove.

The size of the through hole is the same as the size of the locking hole. The size of the baffle 72 is 1.2 times the size of the through hole. The elastic block 73 is an elastic rubber block. The baffle 72 and the elastic block 73 are both arranged in the cavity. The elastic block 73 is in a compressed state in the cavity. The plug block 71 is inserted in the locking hole. The end of the plug block 71 is flush with the outer wall of the mounting frame 3, so as not to affect the installation of the mounting frame 3. When the guard plate 5 needs to be separated, take a toothpick, a needle or other thin object and press the plug block 71 to move the plug block 71 out of the locking hole, so that the movable block 61 can be moved by the toggle bar 64 to move the movable block 61 away from the locking hole. At the same time, the movable block 61 drives the plug block 62 to move out of the second movable groove through the connecting rod 63. At this time, the guard plate 5 can be moved away from the installation frame 3 to move the plug block 62 out of the second vertical groove to realize the removal of the guard plate 5. In this way, the guard plate 5 and the installation frame 3 can be removed multiple times without affecting the stability of the connection between the guard plate 5 and the installation frame 3.
