They do not indicate or imply that the devices or components referred to must have a specific direction, be constructed, or operate in a specific direction, and therefore should not be construed as limiting this utility model. Furthermore, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0021] Example

[0022] refer to Figure 1-Figure 5 A sandpaper rack for easy replacement of sandpaper comprises a mounting base 1 and a fixing base 2 detachably arranged on the top of the mounting base 1 for fastening the sandpaper 3 mounted on the mounting base 1. The left and right outer walls of the mounting base 1 are symmetrically provided with grooves 101 extending along the length direction of the mounting base 1. A limiting groove 102 is provided on the top end surface of one end of the mounting base 1, and a first fixing groove 103 is provided on the top end surface of the other end of the mounting base 1. A fixing groove 103 is provided on the side of the mounting base 1 close to the first fixing groove 103 and is located at the bottom of the first fixing groove 103 and is aligned with the first fixing groove 103. The fixed groove 103 is connected to the driving groove 104, and a driving rod 105 is slidably connected in the driving groove 104. One end of the driving rod 105 extends to the outside of the driving groove 104 and is provided with a first stop plate 106. The other end of the driving rod 105 is provided with a compression spring 107. One end of the compression spring 107 is fixedly connected to the inner wall of the driving groove 104, and the other end of the compression spring 107 is fixedly connected to the driving rod 105. A locking block 108 with an L-shaped structure is fixedly connected to the top of one end of the driving rod 105 close to the compression spring 107.

[0023] Among them, the bottom of the fixing seat 2 is provided with a mounting groove 201 for the mounting seat 1 to be plugged into, and the inner side wall of the mounting groove 201 is symmetrically provided with a protrusion 202 that can be plugged into the groove 101. The outer end surface of the protrusion 202 is an arc structure. The protrusion 202 is matched with the groove 101 to improve the fastening of the two ends of the sandpaper 3 installed between the fixing seat 2 and the mounting seat 1, so that the sandpaper 3 after installation is firm and reliable, not easy to slip, and has high stability. A limiting plate 203 that can be plugged into the limiting groove 102 is provided on the top of the inner side wall of one end of the fixing seat 2. Through the setting of the limiting plate 203 and the limiting groove 102, the installation of the fixing seat 2 can be limited, and the tightness of the connection between the fixing seat 2 and the mounting seat 1 is strengthened. Tightness, the top end surface of the other end of the fixing seat 2 is penetrated by a second fixing groove 204 connected to the first fixing groove 103, and a fixing column 205 is slidably connected in the second fixing groove 204, and one end of the fixing column 205 extends into the first fixing groove 103. By plugging the fixing column 205 into the first fixing groove 103, the fixing seat 2 and the mounting seat 1 after plugging and installation can be limited and fixed, and the other end of the fixing column 205 extends to the outside of the fixing seat 2 and is provided with a second stop plate 206. A tension spring 207 is provided on the outside of the fixing column 205 between the second stop plate 206 and the fixing seat 2, and one end of the tension spring 207 is fixedly connected to the bottom end surface of the second stop plate 206, and the other end of the tension spring 207 is fixedly connected to the top end surface of the fixing seat 2.

[0024] Specifically, when the fixing seat 2 and the mounting seat 1 are plugged in and installed, the two ends of the sandpaper 3 are clamped between the inner wall of the fixing seat 2 and the outer wall of the mounting seat 1. When the protrusion 202 is plugged in, the sandpaper 3 in the groove 101 is pressed in the groove 101 to form a bend, further increasing the connection strength between the sandpaper 3 and the mounting seat 1 and the fixing seat 2.

[0025] Furthermore, a locking groove 208 is provided on one side of the fixing column 205 for the locking block 108 to engage with. By cooperating with the locking groove 208 and the locking block 108, the fixing base 2 can be tightly locked on the mounting base 1, making the connection between the fixing base 2 and the mounting base 1 more secure.

[0026] Furthermore, a slot 109 is defined in the mounting seat 1 for the locking block 108 to move forward and backward, and the slot 109 is communicated with both the driving slot 104 and the first fixing slot 103 .

[0027] As a further optimization solution, a handle 209 is provided at the center of the top end surface of the fixing seat 2 to facilitate the worker to hold it for grinding work.

[0028] The working principle of this utility model:

[0029] When the second stop plate 206 on the fixing seat 2 is pulled upward, the second stop plate 206 drives the fixing post 205 to move upward until the bottom end of the fixing post 205 is completely received in the second fixing groove 204. At the same time, the tension spring 207 is stretched and elastically deformed, and then the protrusion 202 on the fixing seat 2 is aligned with the groove 101 on the fixing seat 1 for insertion. The two ends of the sandpaper 3 are clamped between the inner side wall of the fixing seat 2 and the outer side wall of the fixing seat 1, and the sandpaper 3 in the groove 101 is pressed into the groove 101 to form a bend when the protrusion 202 is inserted, which further increases the connection strength of the sandpaper 3 with the fixing seat 1 and the fixing seat 2, so that the sandpaper 3 is firmly installed on the fixing seat 1. During the insertion process, the limit plate 203 on the fixing seat 2 is inserted into the fixing seat 1. When the second stop plate 206 is released, the tension spring 207 is elastically reset to drive the fixing post 205 to be inserted into the first fixing groove 103, and then the first stop plate 106 is released. The compression spring 107 is elastically reset to drive the locking block 108 on the driving rod 105 to be clamped into the locking groove 208 on the fixing post 205, thereby locking the fixing seat 2 tightly on the mounting seat 1. When the sandpaper 3 needs to be replaced, the above operation can be reversed to complete the removal of the sandpaper 3, and then the above operation is repeated to install a new sandpaper 3.

[0030] In the description of this utility model, it should be noted that, unless otherwise specified or limited, the terms "connected" and "connection" should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integral connection; mechanical connection, electrical connection; direct connection, or indirect connection through an intermediary. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0031] The above-described embodiments merely represent several implementation methods of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the concept of the present invention, and all such variations and improvements fall within the scope of protection of the present invention.
