[0024] Example 1

[0025] An auxiliary brick-cutting device, such as Figures 1-4 As shown, the device includes a base 1, a brick positioning device and a cutting disc 2 mounted on the base 1. The cutting disc 2 is driven by a motor 3. The brick positioning device includes guide plates 4 on both sides of the base 1, and two positioning seats 5 on the guide plates 4 respectively. The positioning seats 5 are U-shaped clamps with slots facing laterally. Push-pull rods 7 are provided on the U-shaped clamps. Guide channels 6 are provided on the guide plates 4, and the positioning seats 5 are limited within the guide channels 6. The bricks are limited between the two guide plates 4. The push-pull rods 7 push and pull the positioning seats 5 along the guide channels 6 to move towards the cutting disc 2, thereby cutting the bricks. The basic principle is that the positioning seats 5 hold the bricks in place. The block is limited, and the push-pull rod pushes and pulls the positioning seat along the guide channel 6 to cut the brick. A dust cover 13 can be set on the base 1 for dust prevention. In specific use, size marks can be set on the base to assist in brick cutting. An installation groove can be opened in the middle of the top of the base. The cutting disc is rotatably installed inside the installation groove. A drive motor is fixedly installed on one side of the outer wall of the base. An movable hole is opened on one side of the base, and the movable hole communicates with the installation groove. The drive shaft of the cutting disc extends into the movable hole. The output shaft of the drive motor is connected to the drive shaft of the cutting disc through a coupling. The motor drives the cutting disc to rotate, which is a common technical means and will not be described in detail here.

[0026] Example 2

[0027] Based on Embodiment 1, the upper side plates of the two U-shaped clamps are connected by a connecting plate 10. The upper side plates of the U-shaped clamps are hollow plates. The two sides of the connecting plate are respectively inserted into the hollow plates on both sides. In this embodiment, the connecting plate 10 serves as a guide plate for the hollow plates on both sides and can play a guiding role when the positioning seats 5 on both sides are displaced relative to each other or in opposite directions.

[0028] Example 3

[0029] Based on Embodiment 2, a pressing device can be installed on the positioning seat 5. The pressing device includes a pressing plate 8 and a pressing plate lifting device 9. The pressing plate lifting device 9 includes a lifting rod 91, a connecting rod 92, a threaded rod 93, a threaded sleeve 94, and a handwheel 95. The lifting rod 91 is an L-shaped rod structure. The vertical part of the L-shaped rod structure passes through the top surface of the pressing plate 8 and is fixed to the pressing plate 8. The horizontal part is inserted into the threaded rod 93, passes through the threaded sleeve 94, and is connected to the connecting plate 10 through a bearing. The two connecting rods 92 are respectively connected to both sides of the threaded sleeve 94. The handwheel 95 is located at the top of the threaded rod 93 for rotating the threaded rod. During the rotation of the threaded rod, the threaded sleeve 94 moves up and down, and then the connecting rod 92 drives the lifting rod 91 and the pressing plate 8 to press the brick. In this embodiment, the positioning seat 5 can play the role of supporting the brick, and the pressing plate lifting device presses the brick to fix it.

[0030] Example 4

[0031] Based on embodiment 3, the clamping plate 8 and the vertical wall of the U-shaped clamp are slidably connected. The vertical wall of the U-shaped clamp can be provided with a limiting channel for limiting the clamping plate 8, so that the clamping plate is transported vertically as much as possible. The push-pull rod 7 includes a fixed rod fixed on the positioning seats 5 on both sides and a push-pull rod for connecting the fixed rods on both sides. The push-pull rod can serve as a guide rod for the push-pull rods on both sides. The main function of the guide rod is to guide the U-shaped clamps on both sides when they are displaced relative to each other or in opposite directions.

[0032] Example 5

[0033] Based on embodiment 4, the top and bottom surfaces of the guide channel 6 are provided with guide grooves, and the top and bottom surfaces of the positioning seat 5 are provided with guide blocks that are adapted to the guide grooves. The guide blocks are limited within the guide grooves, and the two guide plates 4 can only move relative to each other or back to back, without needing to move laterally along the base. Therefore, the guide channel 6 can be provided on the guide plate 4 to provide a limiting channel for the positioning seat 5.

[0034] The base 1 is also provided with a guide groove 12 for limiting the guide plate 4. The two guide plates 4 are connected by a guide rod 11. The guide plate 4 includes an internal threaded sleeve and a threaded rod threaded on both sides of the internal threaded sleeve. The relative or opposite movement of the two guide plates 4 can be realized by the forward and reverse rotation of the internal threaded sleeve. The guide groove 12 provides a limiting guide channel for the relative or opposite movement of the two guide plates.

[0035] Its main working principle is as follows:

[0036] In practical use, the internal threaded sleeve rotates, causing two threaded rods to move in opposite directions, which in turn causes two guide plates to move in opposite directions. This allows adjustment of the distance between the two positioning seats, facilitating the positioning of bricks of different sizes and enabling the cutting of bricks of different sizes. After the distance between the two positioning seats is adjusted, the brick to be cut is placed on the two positioning seats. By rotating the threaded rod with the handwheel, the threaded rod moves the threaded sleeve downward, which in turn moves the two connecting rods downward. The two connecting rods then move the two lifting rods downward, allowing the two lifting rods to move the two pressing plates downward until the two pressing plates contact the top sides of the brick, achieving the function of pressing and positioning the brick. Once the brick is positioned, the push-pull rod and two fixing rods push the two positioning seats to move within the two rectangular movable openings, allowing the two positioning seats to move with the brick. At the same time, the drive motor is started to rotate the cutting disc. When the brick moves to the cutting disc, it can be cut. The dust cover 2 prevents dust from splashing.

[0037] The parts not covered in this utility model are the same as or can be implemented using existing technologies.

[0038] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects.
