[0028] A square pressing plate 2 is movably inserted in the sleeve 1. An operating rod 4 is provided on a side of the pressing plate 2 away from the auxiliary demoulding cover 8. The pressing plate 2 divides the sleeve 1 into a mortar area close to the auxiliary demoulding cover 8 and an operating area. The end surface of the mortar area where the pressing plate 2 is located is provided with a mortar outlet connected to the operating area.

[0029] In the above technical solution, a transparent window 3 is provided on the side wall of the sleeve 1, and the transparent window 3 is arranged along the central axis direction of the sleeve 1. A scale is provided on the transparent window 3 so that workers can observe the scale where the mortar is located and then make a mortar cake of suitable thickness. It should be noted that the starting end (0) of the scale is counted from the large area end of the auxiliary demoulding cover 8; the structure of the auxiliary demoulding cover 8 is as follows Figures 1-2As shown, it is a trapezoidal column, composed of four trapezoidal faces, one end of the auxiliary demoulding cover 8 is a small area end, and the other end is a large area end, the small area end refers to the end where the shorter side (upper bottom) of the trapezoid is located, and correspondingly, the large area end refers to the end where the longer side (lower bottom) of the trapezoid is located, the port of the small area end of the auxiliary demoulding cover 8 is consistent with the port of the sleeve 1 (shape, size), and the size of the large area end of the auxiliary demoulding cover 8 is designed according to actual conditions, such as: when the sleeve 1 is a square sleeve 1, the side length of the cross-section of the sleeve 1 is 50mm, the large area end of the auxiliary demoulding cover 8 is also a square, and its side length can be designed to be 70mm, and the structure of the auxiliary demoulding cover 8 is convenient for demoulding; the pressing plate 2 and the sleeve 1 are movably plug-in connected, that is, the pressing plate 2 can be inserted in the sleeve 1, and can also be detached from the sleeve 1. When the pressing plate 2 is inserted When in the sleeve 1, the inner cavity of the sleeve located on the side of the pressing plate 2 close to the auxiliary demolding cover 8 is the mortar area, and the other side is the operation area. The end face of the mortar area where the pressing plate 2 is located is provided with a mortar outlet. Here, it can be regarded as that the sleeve 1 located on the side of the pressing plate 2 close to the auxiliary demolding cover 8 and the pressing plate 1 form a cavity with an open end, and the cavity is provided with a mortar outlet on the side wall where the pressing plate 2 is located; the setting of the mortar outlet can be: the length of each side of the pressing plate 2 is slightly smaller than the length of each side of the sleeve 1, such as 2 to 3 mm smaller. At this time, the gap between the pressing plate 2 and the inner wall of the sleeve 1 forms a mortar outlet, and also satisfies the purpose of the pressing plate 2 moving in and out of the sleeve 1. Alternatively, the pressing plate 2 is adapted to the inner cavity of the sleeve 1 and the pressing plate 2 is slidably connected to the sleeve 1, and a perforation is opened on the pressing plate 2 to form a mortar outlet. It is adaptively selected according to actual conditions;

[0030] In this technical solution, by designing a sleeve 1, a transparent window 3, a scale, an auxiliary demoulding cover 8, a pressing plate 2, an operating rod 4, and a mortar outlet, when in use, mortar is poured into the sleeve 1, the auxiliary demoulding cover 8 of the sleeve 1 is attached to the wall surface of the plastering cake, the pressing plate 2 is inserted into the sleeve 1, and then the worker fixes the sleeve 1 with one hand and operates the operating rod 4 with the other hand to drive the pressing plate 2 to squeeze the mortar in the mortar area, and by observing the scale, the mortar in the mortar area is squeezed into a plaster cake of a desired thickness. During the squeezing process, excess mortar is squeezed from the mortar outlet to the operating area. When demoulding, the worker applies a slight force to the operating rod 4 to make the pressing plate 2 abut against the plaster cake, and then moves the sleeve 1 backward with the other hand to press the plaster cake against the sleeve. The connection of the tube 1 is loose. Under the dual effects of the auxiliary demoulding cover 8 and the pressing plate 2 pressing the ash cake, the worker can easily remove the ash cake from the sleeve 1. When the demoulding is successful, the pressing plate 2 is moved away from the ash cake, and the entire device can be easily removed from the wall. Compared with the existing structure, the demoulding effect of the utility model is better; when the demoulding is successful, the mortar on the inner wall of the sleeve 1 needs to be scraped off. At this time, the operating rod 4 is operated to drive the pressing plate 2 to repeatedly scrape off the mortar adhered to the inner wall of the sleeve 1, so that the mortar on the inner wall of the sleeve 1 is cleaned. Compared with the existing strip slot design, the sleeve inner wall of the utility model has relatively fewer dead angles, and the mortar can be scraped off more cleanly without clogging, which is conducive to the reuse of the device.

[0031] In another technical solution, the operating rod 4 is a round rod and the end of the operating rod 4 away from the pressure plate 2 is a smooth curved surface; the beneficial effect obtained by adopting this technical solution is that by designing the operating rod 4 as a round rod and designing the end of the operating rod 4 away from the pressure plate 2 as a curved surface, it is convenient for workers to hold the operating rod and the comfort of holding the operating rod 4 is improved.

[0032] In another technical solution, the sleeve 1 is a square sleeve, the pressure plate 2 is a square plate, the side length of the cross section of the pressure plate 2 is 2 mm smaller than the side length of the cross section of the sleeve 1, and when the pressure plate 2 is inserted into the sleeve 1, the gap between the pressure plate 2 and the inner wall of the sleeve 1 forms the mortar outlet; the beneficial effect of adopting this technical solution is that a structure in which the pressure plate 2 and the sleeve 1 are movably inserted and connected is provided, which has a simple structure and is easy to process.

[0033] In another technical solution, the sleeve 1 is a square sleeve, and the pressing plate 2 is a square plate; the pressing plate 2 is adapted to the inner cavity of the sleeve 1 and is slidably connected to the inner wall of the sleeve 1, and an opening 5 is provided on the pressing plate 2 to form the mortar outlet, and a resilient cover plate 6 is provided at the opening 5, so that when an external force pulls the cover plate 6, the cover plate 6 closes the opening 5, and a support plate 7 is provided at one end of the cover plate 6 close to the operating rod 4, and the support plate 7 is arranged along the length direction of the operating rod 4; specifically, the pressing plate 2 ... cavity of the sleeve 1 and is slidably connected to the inner wall of the sleeve 1; The block 9 is slidably connected with the inner wall of the sleeve 1 in the form of a slide groove. The matching of the pressure plate 2 with the inner cavity of the sleeve 1 means that when the pressure plate 2 is extended into the corresponding slide groove through the slider, the pressure plate 2 covers the inner cavity of the sleeve 1 (the four side walls of the pressure plate 2 are correspondingly attached to the four inner walls of the sleeve 1); an opening 5 is provided on the pressure plate 2, and a resilient cover plate 6 is provided at the opening 5. The specific structure is as follows: a mounting groove 10 is provided on the inner wall of the opening 5 away from the operating rod 4, and the open end of the mounting groove 10 is connected to the opening 5.
