DETAILED DESCRIPTION

[0037] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. The embodiments described below with reference to the drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0038] The following describes an embodiment of the present invention based on its overall structure. Example 1:

[0039] A tung oil modified resin hot pressed electric wood board, such as Figures 1-6 As shown, it includes an electric board body 1, and a clamping assembly 3 is provided on the top of the electric board body 1. The clamping assembly 3 includes four slots 302 opened on the top of the electric board body 1, and the slots 302 are plugged with plug blocks 301. Spring rods 303 are installed on both sides of the slots 302, and one end of the spring rod 303 is connected to a clamping block 304. A cutting mat 2 is installed between the four plug blocks 301. The cutting mat 2 is made of high-strength rubber material. When installing the cutting mat 2, the plug block 301 at the bottom of the cutting mat 2 can be inserted into the slot 302, which is convenient for positioning the cutting mat 2 first. One side of the clamping block 304 is fitted with the plug block 301, and the clamping block 304 is slidably connected to the slide groove 305 through a slider 306. When the clamping block 304 moves, it will drive the slider 306 to slide inside the slide groove 305, and the clamping block 304 will squeeze the spring rod 303, so that the spring rod 303 is compressed.

[0040] Specifically, the top of the clamping block 304 and the bottom of the inserting block 301 are both inclined, so that when the inserting block 301 is inserted into the slot 302, the inserting block 301 can push the clamping block 304 to move, and the cutting pad 2 is detachably connected to the bakelite board body 1 through the inserting block 301. The bottom of the cutting pad 2 fits with the top of the bakelite board body 1, which is convenient for disassembly of the cutting pad 2, so that the cutting pad 2 can be replaced. Storage components 4 are provided on both sides of the bakelite board body 1, and the storage component 4 includes a splicing groove 401 opened on one side of the bakelite board body 1 and a storage groove 404 opened on the other side of the bakelite board body 1.

[0041] Specifically, a splicing block 405 is inserted into the interior of the storage slot 404, a baffle 402 is provided inside the splicing slot 401, and a movable rod 403 that penetrates the bakelite body 1 is connected between the baffle 402 and the splicing block 405. When the baffle 402 is pushed to move, the baffle 402 will drive the movable rod 403 to move, and then drive the splicing block 405 to move, so that the baffle 402 moves into the innermost part of the splicing slot 401, and the splicing block 405 will be removed from the storage slot 404. Move it out from the inside, the outer wall of the baffle 402 fits with the inner wall of the splicing groove 401, and the baffle 402 is slidably connected to the splicing groove 401. When there is no need to splice the bakelite board, the baffle 402 can cover the splicing groove 401, thereby preventing external impurities from entering the splicing groove 401. The splicing block 405 is adapted to the splicing groove 401, and the splicing block 405 is slidably connected to the storage groove 404, which facilitates the insertion of the splicing block 405 into the splicing groove 401, and then the bakelite board can be spliced. Example 2:

[0042] On the basis of the above-mentioned embodiment 1, in order to improve the stability of the clamping block 304 during movement, the clamping block 304 needs to be guided, and thus the following structure is provided.

[0043] Specifically, two slide grooves 305 are provided at the lower part of the slot 302, and a slider 306 is provided inside the slide groove 305. The top of the slider 306 is connected to the bottom of the clamp 304. When the clamp 304 moves, it will drive the slider 306 to slide inside the slide groove 305, thereby improving the stability of the clamp 304 when moving. Example 3:

[0044] On the basis of the above-mentioned embodiment 1, in order to facilitate locking and limiting the splicing block 405 and prevent the splicing block 405 from moving at will, the following structure is provided.

[0045] See Figure 1 、 Figure 2 、 Figure 3 and Figure 6A first threaded hole 406 and a second threaded hole 407 are respectively provided on the top of the splicing block 405. The aperture of the first threaded hole 406 is the same as the aperture of the second threaded hole 407. A locking screw 408 extending into the second threaded hole 407 is also installed on one side of the top of the bakelite board body 1, so that the locking screw 408 can be screwed into the first threaded hole 406 or the second threaded hole 407. When the locking screw 408 is screwed into the first threaded hole 406 or the second threaded hole 407, the splicing block 405 can be locked and fixed.

[0046] The working principle of the present invention is as follows: first, when the cutting mat 2 needs to be installed, the staff can simultaneously insert the four inserting blocks 301 at the bottom of the cutting mat 2 into the slots 302. When the inserting blocks 301 are inserted, they push the clamping blocks 304 to move, so that the clamping blocks 304 squeeze the spring rods 303. When the inserting blocks 301 are fully inserted into the slots 302, the clamping blocks 304 are subjected to the reaction force of the spring rods 303 and tightly clamp the inserting blocks 301, thereby achieving the purpose of limiting the position of the inserting blocks 301 and the cutting mat 2. When removing the cutting mat 2, the staff only needs to pull the cutting mat 2 upward to remove the inserting blocks 301 from the slots 302, and the cutting mat 2 can be removed and replaced.

[0047] When the bakelite does not need to be spliced, the splicing block 405 is located inside the receiving groove 404, and the locking screw 408 is screwed into the first threaded hole 406 to lock the splicing block 405, while the baffle 402 moves to the notch position of the splicing groove 401 to block the splicing groove 401 and prevent impurities from entering the splicing groove 401.

[0048] When the bakelite boards need to be spliced, the locking screw 408 can be unscrewed from the first threaded hole 406, and then the baffle 402 can be pushed so that the baffle 402 drives the movable rod 403 to move, and then drives the splicing block 405 to move, so that the baffle 402 moves into the innermost part of the splicing groove 401, and the splicing block 405 will move out from the inside of the storage groove 404, and then the locking screw 408 is screwed into the second threaded hole 407 to lock and limit the splicing block 405, so that the splicing block 405 can be inserted into the splicing groove 401 on another bakelite board, thereby completing the splicing of the bakelite boards.

[0049] Although embodiments of the present invention have been shown and described, these specific embodiments are merely explanations of the present invention and are not limitations on the present invention. The specific features, structures, materials, or characteristics described may be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions, and variations to the embodiments as needed without departing from the principles and purpose of the present invention, but as long as they are within the scope of the claims of the present invention, they are protected by patent law.
