[0025] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0026] Please refer to Figure 1 An embodiment of the present invention provides a telescopic saw table, including a frame 1, a movable plate 2, a push rod 3, a three-section telescopic guide rail 4, a saw table panel 5 and other components. The following describes in detail the various components of this embodiment in conjunction with the accompanying drawings.

[0027] like Figure 1 and Figure 2 As shown, the saw table panels 5 can be provided with two pieces and are respectively installed on both sides of the top of the frame 1, and two three-section telescopic guide rails 4 are provided and are respectively fixed between the two sides of the top of the frame 1 at intervals. The bottom sides of the movable plate 2 and the frame 1 are slidably connected through the three-section telescopic guide rails 4. The two saw table panels 5 are respectively located on both sides of the movable plate 2 and remain level with the movable plate 2. The push rod 3 is horizontally installed through the three-section telescopic guide rail 4 and can be slidably connected to the movable plate 2 and one end of the saw table panel 5.

[0028] Among them, the frame 1 serves as a supporting structure, providing basic stable support for the saw table as a whole. The saw table panel 5 provides a stable cutting platform, which is convenient for cutting operations. The movable plate 2 can be slidably connected to the frame 1 through the three-section telescopic guide rail 4 to achieve flexible movement, which increases the range and convenience of the pushing plate operation. The push rod 3 can further expand the pushing plate range on the saw table, and can be suitable for wider wooden boards, thereby improving work efficiency.

[0029] The three-section telescopic guide rail 4 in this embodiment can adopt the three-section telescopic guide rail commonly found on the market. This embodiment does not impose any restrictions on it. The telescopic design of the three-section telescopic guide rail can adapt to different cutting requirements, ensure smooth sliding of the movable plate 2 and the push rod 3, reduce wear, and increase service life.

[0030] like Figure 3 and Figure 4 As shown, in a specific implementation, the movable plate 2 can slide forward and backward relative to the frame 1 through the three-section telescopic guide rail 4, and the push rod 3 can slide forward and backward relative to the movable plate 2 and the saw table panel 5 through the three-section telescopic guide rail 4.

[0031] like Figure 5 As shown, in this embodiment, a limiting piece 7 and a knob lock 8 can also be included. The structure of the limiting piece 7 is set to be L-shaped. The back of the limiting piece 7 is fixedly connected to the bottom surface of the movable plate 2 and is set downward. The knob lock 8 is installed on the outer surface of the frame 1 and is located below the limiting piece 7. When the knob lock 8 is rotated, the tongue of the knob lock 8 can extend upward and abut against the limiting piece 7, thereby achieving the limitation of the movable plate 2.

[0032] During specific implementation, by turning the knob lock 8 to extend its tongue, the movable plate 2 can be limited quickly and conveniently, so that the movable plate 2 is fixed between the saw table panels 5 to prevent it from unnecessary movement, thereby enhancing the flexibility of operation and allowing the operator to quickly adjust according to needs.

[0033] In this embodiment, two flippers 6 can also be included. The two sides of the push rod 3 are flipped and connected with one end of the two three-section telescopic guide rails 4 through the flippers 6. The push rod 3 can be flipped from the top of the movable plate 2 and the saw table panel 5 to the outside of one end of the movable plate 2 and the saw table panel 5 through the flippers 6.

[0034] like Figure 6 and Figure 7 As shown, the flipper 6 may include a flip block 61, a fixed block 62, a connecting rod 63 and a buckle 64. The cross-sections of the fixed block 62 and the flip block 61 are both in an inverted U-shaped structure. One end of the fixed block 62 is fixedly connected to one end of the three-section telescopic guide rail 4. The back of the flip block 61 is hinged to the bottom of the other end of the fixed block 62. The connecting rod 63 is laterally connected between the inner surfaces of both sides of the fixed block 62. The end of the buckle 64 is rotatably connected to the connecting rod 63. The front of the flip block 61 is provided with a square hole 611 for the front end of the buckle 64 to pass through and be clamped with each other.

[0035] When the flipper 6 is in the locked state, the flipping block 61 of the flipper 6 is connected to the fixed block 62 through the buckle 64, and the flipping block 61 and the fixed block 62 are in a right-angle structure, which can keep the push rod 3 locked on the top surface of the movable plate 2 and the saw table panel 5, preventing it from loosening and displacement during the cutting process;

[0036] When the flipper 6 is in the unlocked state, when the operator manually pushes the buckle 64 upwards, the flip block 61 can be flipped downward relative to the fixed block 62, and the flip lock of the push rod 3 is released, and the push rod 3 can be flipped from the movable plate 2 and the saw table panel 5 to the unfolded state.

[0037] In specific implementation, when the push rod 3 is located on the outside of the top surface of the movable plate 2 and the saw table panel 5, it can assist in abutting and pushing the wooden board extending out of the movable plate 2 or the saw table panel 5 toward the push plate direction (the direction indicated by the dotted arrow in the figure), and can remain level with the movable plate 2 or the saw table panel 5 after being flipped down, so that it can serve as an auxiliary support rod for the wooden board, further expanding the extension area of ​​the saw table, and meeting the use needs of various larger boards.

[0038] like Figures 8 to 10 As shown, the three-section telescopic guide rail 4 can include a first rail 41, a second rail 42, a third rail 43, a connector 44, a bearing mounting seat 45 and a plurality of bearings 46. The bottom surface of the first rail 41 is fixedly connected to the top surface of the frame 1, and the top surface of the second rail 42 is fixedly connected to the bottom surface of the movable plate 2. The inner side surfaces of the first rail 41, the second rail 42 and the third rail 43 are respectively provided with a concave rail movable groove 47 extending along the length direction thereof. The top and bottom of each rail movable groove 47 are embedded and fixed with a circular guide column 48 symmetrically arranged along the length direction thereof. The sub-bearings 46 are rotatably mounted on both side surfaces of the bearing mounting seat 45 and are slidably connected to the track movable grooves 47 of the first track 41 and the second track 42, and can cooperate with the circular guide posts 48 in the track movable grooves 47 of the first track 41 and the second track 42 to roll. The connecting member 44 is fixedly connected to the bottom extending horizontally outward from the top of the outer side surface of the second track 42. The other part of the bearings 46 are rotatably mounted on the outer side surface of the connecting member 44 and are slidably connected to the track movable groove 47 of the third track 43, and can also cooperate with the circular guide posts 48 in the track movable groove 47 of the third track 43 to roll.

[0039] Furthermore, the three-section telescopic guide rail 4 can also include a magnet 451. The two ends of the first rail 41 and the second rail 42 and the end of the third rail 43 away from the flipper 6 are respectively provided with metal baffles 49 that can close the two end ends of the rail movable groove 47. There are two magnets and they are respectively installed on the head end faces of the bearing mounting seat 45. The bearing mounting seat can preferably adopt a split structure.

[0040] Among them, each magnet 451 can achieve magnetic attraction cooperation with its corresponding metal baffle 49, ensuring that when the guide rail is reset after being unfolded, the metal baffle 49 of the first track 41 or the second track 42 can pull the bearing mounting seat 45 to reset through suction.

[0041] like Figure 11 As shown, it can also include a saw blade 9 and an electric saw device 91. The electric saw device 91 is fixedly installed upward at the bottom of one of the saw table panels 5. The saw blade 9 is transmission-connected to the electric saw device 91 and extends out of the rectangular slot 51 that is opened through the saw table panel 5.

[0042] To sum up, the utility model can realize a flexible sliding and retractable design by combining the movable plate and the push rod with the three-section telescopic guide rails respectively, thereby expanding the cutting stroke of the wooden board, so that the operating area of ​​the saw table can be extended or contracted as a whole, and can also be suitable for the cutting needs of various sizes of boards while the overall width of the saw table is relatively small. It is flexible and simple to operate and has a compact structure, which makes it convenient for workers to carry and load it for storage and transportation. In addition, the three-section telescopic guide rails make the advancement of the movable plate and the push rod more stable and smooth, making the cutting work smoother and easier, reducing labor intensity and improving cutting accuracy.

[0043] The above embodiments are preferred implementation methods of the present invention, but the implementation methods of the present invention are not limited to the above embodiments. Any other changes, modifications, substitutions, combinations, and simplifications that do not deviate from the spirit and principles of the present invention should be considered as equivalent replacement methods and are included in the scope of protection of the present invention.
