Specifically, when adjacent frame bodies 1 are spliced, the fixing block 404 firstly extends into the corresponding fixing groove 3, and then the T-shaped fixing block 404 is controlled to rotate by 90 degrees in the fixing groove 3 through the sliding of the toggle block 408, so that the fixing block 404 is clamped inside the fixing groove 3 and cannot be separated, and the mounting is realized.

Example 2

The basic structure of the steel mesh mold of this embodiment is the same as that of embodiment 1, and further, the fixing mechanism 4 further includes a worm wheel 403 disposed at the lower portion of the locking column 402, wherein the region of the upper portion of the locking column 402 for fitting with the sprocket 406 is a polygonal cylinder structure, and the region of the lower portion for fitting with the worm wheel 403 is a threaded segment, and is fitted with the worm wheel 403 through threads. More specifically, the locking column 402 can be divided into three sections, as shown in fig. 8, the mounting area, which is first passed through the top wall of the frame 1 and extends to the lower cavity, and is matched with the frame 1 in a rotatable manner, and the top wall of the frame 1, generally, a cylindrical section can be adopted, and the frame 1 is correspondingly provided with a matching circular hole, so that not only can the locking column 402 be matched in a rotatable manner in the frame 1, but also the locking column 402 can be matched in a lifting manner in the frame 1.

Then the locking post 402 is used for the region of the cooperation installation with sprocket 406 downwards for polygon cylinder structure, if can adopt the cylinder section that the cross-section is the rectangle, the sprocket 406 center corresponds and has seted up rectangular mating holes for sprocket 406 inevitably drives locking post 402 synchronous rotation when rotating, but when sprocket 406 high position did not change, locking post 402 can carry out the lift change in height.

Finally, the lower portion of the locking column 402 is provided with a threaded section for fitting with the worm wheel 403, and is fitted with the worm wheel 403 through threads, the frame 1 is internally provided with support plates 401 at the upper and lower sides of the worm wheel 403, respectively, the worm wheel 403 is located in a cavity between the upper and lower support plates 401, that is, the height position of the worm wheel 403 is limited by the two layers of support plates 401, a worm 405 for fitting with the worm wheel 403 for transmission is correspondingly arranged in the cavity in the frame 1, two ends of the worm 405 are fitted with the frame 1 in a rotating manner, respectively, and at least one end of the worm 405 extends out of the inner wall of the frame 1 and faces the outside.
