It is mainly used to hold the paper in place when writing or practicing calligraphy, preventing the paper from slipping, curling, or shifting, thereby improving the stability of the writing experience.

[0003] Existing technologies, such as the utility model patent with publication number CN218489372U, disclose a newspaper clip. This patent employs a housing, a first hole, and a punching mechanism, including a bearing. The bearing is fixedly installed on the surface of the housing, and a lead screw is fixedly installed inside the bearing. The surface of the lead screw passes through a lead screw nut, and one end of the lead screw is fixedly installed inside a crank handle. The lead screw nut is fixedly installed inside a connecting push rod, one side of which penetrates the housing. A push plate is fixedly installed on the side of the connecting push rod that penetrates the housing. A groove is formed on the surface of the push plate that is close to the first hole. A punching nail is fixedly installed in the groove of the push plate. When a newspaper is placed into the device, one end of the newspaper will align when it contacts the inside of the housing. Then, by rotating the handle, the push plate is pushed, and the punching nail will punch a hole in the newspaper when it contacts the edge of the newspaper through the pushing force of the connecting push rod.

[0004] The inventors discovered the following problems in their daily work when using water-writing paper clamps: the existing clamps have poor clamping effect on water-writing paper, the corners of the clamped side of the water-writing paper are prone to curling up, the clamping force is weak, the paper is easy to slip, which affects the progress of writing practice. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies, such as weak clamping force, poor stability, easy paper slippage, and easy corner curling.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a reusable water-writing paper fixing clip for calligraphy practice, comprising a base plate, with practice paper abutting against the upper surface of the base plate, an adjustment structure provided on one side of the base plate, the adjustment structure comprising a fixing plate, the fixing plate being fixedly connected to the base plate, an adjustment rod being rotatably connected to the upper surface of the fixing plate, a support plate being threadedly connected to the arc surface of the adjustment rod, two round rods being fixedly connected to the upper surface of the fixing plate, the arc surfaces of the two round rods being slidably connected to the support plate, two connecting rods being slidably connected to both ends of the support plate, a clamping plate being fixedly connected to one end of the two connecting rods near the base plate, and two positioning rods being fixedly connected to the upper surface of the base plate, the arc surfaces of the two positioning rods being slidably connected to the clamping plate.

[0007] The above components achieve the following effects: force is transmitted through the adjusting rod, and the edge of the practice paper is clamped by the clamping plate, resulting in high clamping stability and applicability to practice papers of various widths.

[0008] Preferably, an anti-slip pad, which is a rubber pad, is fixedly connected to the lower surface of the clamping plate.

[0009] The effect achieved by the above components is to increase the friction on the lower surface of the clamp through the anti-slip pad, so that the clamp has a better limiting effect on the practice paper.

[0010] Preferably, a plurality of baffles are fixedly connected to the upper surface of the base plate, and the height of the plurality of baffles is less than the height of the positioning rod.

[0011] The effect achieved by the above components is to neatly lay the practice paper on the base plate with the help of the baffle, making it convenient for the user to operate.

[0012] Preferably, the upper end of the positioning rod is arc-shaped.

[0013] The effect achieved by the above components is that the upper end of the positioning rod is arc-shaped, which makes it easy for the clamping plate to slide onto the positioning rod.

[0014] Preferably, the upper end of the adjusting rod is fixedly connected with a plurality of anti-slip protrusions, and the plurality of anti-slip protrusions are evenly distributed on the adjusting rod.

[0015] The effect achieved by the above components is to increase the friction at the upper end of the adjusting rod through the anti-slip protrusions, making it easier for the user to rotate the adjusting rod.

[0016] Preferably, the base plate has auxiliary structures on both sides, the auxiliary structures including two slide rails, the two slide rails being fixedly connected to the base plate, the slide rails having sliders slidably connected to their surfaces, the upper surfaces of the sliders having auxiliary rods fixedly connected to their upper surfaces, the arc surfaces of the two auxiliary rods having magnetic pressure plates slidably connected to their upper surfaces, and the lower surfaces of the base plate having magnetic suction plates fixedly connected to their lower surfaces at positions corresponding to the slide rails, the magnetic suction plates being attracted to the magnetic pressure plates.

[0017] The above components achieve the following effects: the magnetic pressure plate and the magnetic suction plate attract each other, and the magnetic pressure plate further limits the position of the practice paper, so that the unlimited end of the practice paper is attached to the base plate, which allows the practice paper to be laid flat on the work surface and prevents the practice paper from floating and affecting the work.

[0018] Preferably, a handle is fixedly connected to the upper surface of the magnetic pressure plate, and the handle has a "T" shaped cross-section.

[0019] The effect achieved by the above components is that the operating handle moves the magnetic pressure plate, making it convenient for the user to move the magnetic pressure plate by leveraging the force.

[0020] In summary, the beneficial effects of this utility model are as follows:

[0021] In this invention, an adjustment structure is set up, and force is transmitted through the adjustment rod to drive the support plate to move. The support plate cooperates with the clamping plate through the connecting rod, so that the clamping plate and the base plate can clamp the practice paper. The clamping force is large and the stability is high. After the positioning rod releases the limit on the clamping plate, the clamping plate can be operated away from the area on the base plate where the paper is to be placed, which is convenient for the user. The long strip clamping plate is suitable for clamping practice paper of various widths and sizes, and has high practicality.

[0022] By setting up an auxiliary structure, the magnetic pressure plate and the magnetic suction plate are attracted to each other. The magnetic pressure plate further limits the position of the practice paper, so that the unlimited end of the practice paper is attached to the base plate. This allows the practice paper to be laid flat on the work surface, preventing the practice paper from floating and affecting the work. Attached Figure Description

[0029] The present invention will be further illustrated below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the present invention, and these equivalent forms also fall within the scope defined by the appended claims.

[0030] Reference Figure 1As shown, this utility model provides a technical solution: a calligraphy practice reusable water-writing paper fixing clip, including a base plate 1, a practice paper 2 abutting the upper surface of the base plate 1, an adjustment structure 3 on one side of the base plate 1, and auxiliary structures 4 on both sides of the base plate 1.

[0031] The specific settings and functions of its adjustment structure 3 and auxiliary structure 4 will be discussed below.

[0032] Reference Figure 2 , Figure 3 As shown in this embodiment: the adjusting structure 3 includes a fixed plate 31, which is fixedly connected to the base plate 1. An adjusting rod 32 is rotatably connected to the upper surface of the fixed plate 31. A support plate 33 is threadedly connected to the arc surface of the adjusting rod 32. Two round rods 34 are fixedly connected to the upper surface of the fixed plate 31. The arc surfaces of the two round rods 34 are slidably connected to the support plate 33. Two connecting rods 35 are slidably connected to both ends of the support plate 33. A clamping plate 36 is fixedly connected to one end of the two connecting rods 35 near the base plate 1. Two positioning rods 37 are fixedly connected to the upper surface of the base plate 1. The arc surfaces of the two positioning rods 37 are slidably connected to the clamping plate 36. Force is transmitted through the adjusting rod 32, and the clamping plate 36 is used to clamp the edge of the exercise paper 2. The clamping stability is high and it is suitable for exercise papers of various widths. 2. A non-slip pad 38 is fixedly connected to the lower surface of the clamping plate 36. The non-slip pad 38 is a rubber pad. The non-slip pad 38 increases the friction of the lower surface of the clamping plate 36, making the clamping plate 36 better limit the exercise paper 2. Several baffles 39 are fixedly connected to the upper surface of the base plate 1. The height of the baffles 39 is less than the height of the positioning rod 37. The baffles 39 help to neatly lay the exercise paper 2 on the base plate 1, making it convenient for the user to operate. The upper end of the positioning rod 37 is arc-shaped, which makes it easy for the clamping plate 36 to slide onto the positioning rod 37. Several non-slip protrusions are fixedly connected to the upper end of the adjusting rod 32. The non-slip protrusions are evenly distributed on the adjusting rod 32. The non-slip protrusions increase the friction of the upper end of the adjusting rod 32, making it convenient for the user to rotate the adjusting rod 32.

[0033] Reference Figure 4 , Figure 5As shown in this embodiment: the auxiliary structure 4 includes two slide rails 41, which are fixedly connected to the base plate 1. A slider 42 is slidably connected to the surface of the slide rails 41. An auxiliary rod 43 is fixedly connected to the upper surface of the slider 42. A magnetic pressure plate 44 is slidably connected to the arc surfaces of the two auxiliary rods 43. A magnetic suction plate 45 is fixedly connected to the lower surface of the base plate 1 at the position corresponding to the slide rails 41. The magnetic suction plate 45 and the magnetic pressure plate 44 are attracted to each other. The magnetic pressure plate 44 and the magnetic suction plate 45 are attracted to each other. The magnetic pressure plate 44 is used to further limit the exercise paper 2, so that the end of the exercise paper 2 that is not limited is attached to the base plate 1, so that the exercise paper 2 can be unfolded flat on the exercise paper 2 and the exercise paper 2 is prevented from floating and affecting the work. A handle 46 is fixedly connected to the upper surface of the magnetic pressure plate 44. The cross section of the handle 46 is "T" shaped. The operation handle 46 drives the magnetic pressure plate 44 to move, which makes it convenient for the user to move the magnetic pressure plate 44 with force.

[0034] Detailed Instructions for Use: By setting the adjustment structure 3, first rotate the adjustment rod 32. The adjustment rod 32, through the thread, drives the support plate 33 to move upward along the round rod 34. The support plate 33, through the two connecting rods 35, drives the clamping plate 36 upward away from the base plate 1. During this process, the clamping plate 36 moves upward along the positioning rod 37. When the clamping plate 36 is fully disengaged from the positioning rod 37, the positioning rod 37 releases its restriction on the clamping plate 36. At this time, the clamping plate 36 can be pushed towards the support plate 33. The clamping plate 36 drives the connecting rods 35 to move towards the support plate 33, so that the clamping plate 36 is away from the area on the base plate 1 where the paper is to be placed. Then, take out the practice paper 2 and lay it on the base plate 1. Then, move it away from the support plate 33. Move the clamping plate 36 so that it is directly above the positioning rod 37. Rotate the adjusting rod 32 in the opposite direction. The adjusting rod 32 drives the support plate 33 to move downward through the thread. Similarly, the clamping plate 36 is placed downward on the positioning rod 37 and presses down on the practice paper 2, fixing the practice paper 2 on the base plate 1. The anti-slip pad 38 increases the friction on the lower surface of the clamping plate 36, making the clamping plate 36 more effective in limiting the position of the practice paper 2. The baffle 39 neatly lays the practice paper 2 on the base plate 1 for easy operation. The upper end of the positioning rod 37 is arc-shaped, which makes it easy for the clamping plate 36 to slide on the positioning rod 37. The anti-slip protrusion increases the friction at the upper end of the adjusting rod 32, making it easy for the user to rotate the adjusting rod 32.

[0035] By setting the auxiliary structure 4, the magnetic pressure plate 44 is first moved upward. The magnetic pressure plate 44 is disengaged from the base plate 1 along the auxiliary rods 43 at both ends. Then, the magnetic pressure plate 44 is moved away from the fixed plate 31. The magnetic pressure plate 44 drives the slider 42 to move along the slide rail 41 through the auxiliary rods 43. At this time, the magnetic pressure plate 44 is away from the area on the base plate 1 where the paper is to be placed. After the practice paper 2 is laid out, the magnetic pressure plate 44 is moved in the opposite direction to the edge of the practice paper 2. The magnetic pressure plate 44 is slowly released and moves downward towards the base plate 1. The magnetic pressure plate 44 is attracted to the magnetic suction plate 45 and limits the position of the practice paper 2. The operating handle 46 drives the magnetic pressure plate 44 to move, making it convenient for the user to move the magnetic pressure plate 44 with the help of force.
