Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model are within the scope of protection of this utility model.

[0020] like Figure 1 , 2 As shown in Figure 4, this embodiment provides a conveniently adjustable drawing board holder, including a support frame 101. A support cylinder 102 is vertically arranged at the top of the support frame 101, and a support rod 103 is inserted into the support cylinder 102. A placement plate 104 is arranged between the middle parts of the support rods 103, and multiple placement grooves 105 are provided on the placement plate 104. A baffle 106 is arranged between the upper ends of the support rods 103. A horizontal plate 107 is also slidably arranged along the front and back directions on the upper end of the support frame 101. A fixing rod 108 is provided on the horizontal plate 107 as a side wall of the support cylinder 102 for inserting and fixing the support rods 103. Multiple fixing holes 109 are provided at the lower end of the support rods 103 for inserting into the fixing rods 108. The user can place the bottom of the drawing board into the placement groove 105 and make the back of the drawing board abut against the baffle 106, thereby achieving tilted placement of the drawing board and effectively preventing the drawing board from slipping.

[0021] like Figure 3 , 4 As shown, a fixing plate 110 is provided on the top front side of the support frame 101. An adjusting screw 111 is screwed onto the fixing plate 110. The adjusting screw 111 is rotatably connected to the horizontal plate 107. A guide slot 112 is also provided on the fixing plate 110. A guide insert plate 113 is provided on the horizontal plate 107 that is inserted into the guide slot 112.

[0022] The support frame 101 is trapezoidal. The trapezoidal design of the support frame 101 provides good stability.

[0023] like Figure 1 ,4 As shown, a handle 114 is also provided on the adjusting screw 111. The horizontal plate 107 is rotatably connected to the adjusting screw 111 via a bearing 115. The outer ring of the bearing 115 is fixedly connected to the horizontal plate 107, and the inner ring of the bearing 115 is connected to the outer wall of the adjusting screw 111.

[0024] Its effect is that the adjusting screw 111 can be easily turned and adjusted by the handle 114, and the bearing 115 can realize the rotational connection between the horizontal plate 107 and the adjusting screw 111.

[0025] like Figure 3 As shown, a reinforcing support rod 201 is provided at the lower end of the support frame 101, and an anti-slip pad 202 is provided at the bottom of the support frame 101.

[0026] Its effects are as follows: the anti-slip pad 202 at the bottom enhances the friction with the ground, preventing slipping or tipping; the reinforced support rod 201 further strengthens the overall structural strength and reserves installation positions for expanded functions.

[0027] like Figure 2 As shown, at least one support rod 103 is also provided with a receiving groove 203, and a scale line 204 is provided in the receiving groove 203.

[0028] The effect is that the recessed groove 203 on the support rod 103 has a built-in scale line 204, which allows the user to intuitively read the current height value when adjusting the height, making it easy to know the effect of the current height adjustment, and accurately align the fixed rod 108 and the fixed hole 109, thereby improving the adjustment efficiency and accuracy.

[0029] Working principle: When in use, after the user moves the device to a suitable position, he can first turn the adjusting screw 111 by turning the handle 114. With the insertion and cooperation of the guide plate 113 and the guide slot 112, the horizontal plate 107 and the fixed plug rods 108 on both sides will move backward until the fixed plug rods 108 are separated from the fixed plug holes 109, and the fixing of the connection between the support plug cylinder 102 and the support plug rod 103 will be released simultaneously. Then, the placement plate 104, support rod 103, and baffle 106 can be moved up and down synchronously to complete the height adjustment of the placement plate 104. After the fixed insertion hole 109 at the new position corresponds to the fixed insertion rod 108, the adjusting screw 111 can be turned in the opposite direction by turning the handle 114 to move the horizontal plate 107 and the fixed insertion rods 108 on both sides forward until the fixed insertion rod 108 is inserted into the fixed insertion hole 109 at the new position. The connection between the support insertion cylinder 102 and the support insertion rod 103 is fixed synchronously, thereby completing the height adjustment of the placement plate 104 and the drawing board support.

[0030] After adjusting the height of the stand, the user places the bottom of the drawing board into the placement groove 105 on the placement plate 104, and ensures that the back of the drawing board is in contact with the baffle 106, forming a stable tilt angle. The combined action of the baffle 106 and the placement groove 105 effectively prevents the drawing board from slipping.

[0031] The multiple placement grooves 105 on the placement plate 104 can accommodate the bottom of drawing boards of different sizes. Combined with the upper baffle 106, the drawing board can be placed stably at an angle, preventing the drawing board from slipping or tipping over due to external force or accidental contact.

[0032] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0033] The above are preferred embodiments of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
