A slide rail is fixedly installed on the surface of the fixed rod. A slide bar is slidably installed on the surface of the slide rail. A clamping block is fixedly installed on the surface of the slide bar. A threaded rod penetrates through the surface of the slide rail. The surface of the threaded rod is in threaded cooperation with the slide rail. A elastic spring is fixedly installed between the threaded rod and the clamping block. A gear is fixedly installed at the top of the threaded rod. A resisting rod is fixedly installed on the surface of the sleeve. A slide strip is slidably installed on the surface of the slide rail near the gear. The slide strip is arranged in a V shape and an elastic member is provided between the slide strip and the slide rail. One side of the slide strip meshes with the surface of the gear, and the other side contacts the surface of the end of the resisting rod away from the sleeve. A plurality of limiting rods are fixedly installed on the surface of the fixed rod. A buckle is rotatably installed on the surface of the sleeve. The clamping block clamps the plate to keep the plate stable during the cutting process.

[0007] Preferably, a rotating rod is rotatably installed on the surface of the slide rail. A torsion spring is provided between the rotating rod and the slide rail. Arc-shaped blocks are fixedly installed at both ends of the rotating rod. A knob is fixedly installed on the surface of the rotating rod.

[0012] The present utility model provides an adjustable plate cutting fixture. It has the following beneficial effects:

[0013] (1) For this adjustable plate cutting fixture, after pushing the sleeve towards the fixed rod and clamping the buckle to the limiting rod, when the sleeve moves, the gear drives the threaded rod to rotate. When the threaded rod rotates, it moves downward, squeezing the elastic spring, causing the elastic spring to contract and deform, storing elastic potential energy, and reducing the travel of the clamping block on the surface of the slide rail. After the sleeve returns to its original position, the threaded rod moves upward, the clamping block resumes its original travel, and the elastic force of the elastic spring on the clamping block also resumes. By moving the sleeve an appropriate distance towards the fixed rod, the elastic force of the elastic spring on the clamping block is adjusted, and the travel of the clamping block is adjusted. It can effectively clamp plates of different thicknesses without the need to replace the fixture separately, with convenient operation and improved work efficiency.

[0014] (2) In this adjustable sheet cutting fixture, inclined surfaces are provided on both sides of the clamping block, enabling the staff to easily push the sheet between the clamping blocks for clamping. After cutting, rotate the rotating rod, and the arc-shaped blocks at both ends of the rotating rod push open the clamping blocks, and the sheet drops between the clamping blocks, facilitating the staff to pick it up.

Detailed Embodiment

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0021] Please refer to Figures 1-4, the present utility model provides a technical solution: an adjustable sheet cutting fixture, which includes a base 1 and a bracket 2. The bracket 2 is fixedly installed on the top of the base 1. A fixed rod 3 is fixedly installed on the surface of the bracket 2. A sleeve 4 is sleeved on the surface of the fixed rod 3. A slide rail 5 is fixedly installed on the surface of the fixed rod 3. A slide bar 6 is slidably installed on the surface of the slide rail 5. A clamping block 7 is fixedly installed on the surface of the slide bar 6. A threaded rod 8 penetrates through the surface of the slide rail 5. The surface of the threaded rod 8 is in threaded cooperation with the slide rail 5. A elastic spring 9 is fixedly installed between the threaded rod 8 and the clamping block 7. A gear 10 is fixedly installed at the top of the threaded rod 8. A resisting rod 12 is fixedly installed on the surface of the sleeve 4. A slide bar 11 is slidably installed on the surface of the slide rail 5 near the gear 10. The slide bar 11 is arranged in a V shape and is provided with an elastic member between it and the slide rail 5. One side of the slide bar 11 meshes with the surface of the gear 10, and the other side contacts the surface of the end of the resisting rod 12 away from the sleeve 4. A number of limiting rods 13 are fixedly installed on the surface of the fixed rod 3. A buckle 14 is rotatably installed on the surface of the sleeve 4. The clamping block 7 clamps the sheet to keep the sheet stable during the cutting process.

[0022] A rotating rod 16 is rotatably installed on the surface of the slide rail 5. A torsion spring is arranged between the rotating rod 16 and the slide rail 5. Arc-shaped blocks 17 are fixedly installed at both ends of the rotating rod 16. A knob 18 is fixedly installed on the surface of the rotating rod 16. Rotate the knob 18 to open the clamping block 7 and take out the cut sheet.

[0023] Bevel surfaces 15 are arranged on both sides of the clamping block 7. The sheet squeezes the bevel surfaces 15 to push open the clamping block 7, which is convenient for clamping.

[0024] The bottom of the clamping block 7 is perpendicular to the slide rail 5, and the contact surface between the clamping block 7 and the sheet remains parallel, ensuring that the clamping block 7 fits the surface of the sheet after clamping the sheet and ensuring the clamping effect.

[0025] The distance between each limiting rod 13 is equal. Each time the buckle 14 clamps the limiting rod 13, the threaded rod 8 moves the same distance.

[0026] The rotating rod 16 is arranged obliquely so that the arc surfaces on the surfaces of the arc-shaped blocks 17 at both ends of the rotating rod 16 contact the surface of the slide bar 6.

[0027] Align the plate to be cut with the gap between the clamp blocks 7, move the plate until it contacts the inclined surface 15 on the side of the clamp block 7, and the moved plate pushes the inclined surface 15 on the surface of the clamp block 7 to push the clamp block 7 open, so that the plate can smoothly enter the clamp block 7. The clamp block 7 applies pressure to the plate under the elastic action of the elastic spring 9 to clamp the plate, so that the plate remains stable during cutting. The clamp block 7 needs to be adjusted for plates of different thicknesses, and the sleeve 4 is pushed. The moving sleeve 4 drives the push rod 12 to move in the direction of the slide bar 11, and the push rod 12 squeezes the slide bar when it moves. One side of 11 makes the slide bar 11 slide, and the other side of the sliding slide bar 11 pushes the gear 10 meshing therewith to make the gear 10 rotate, and the rotating gear 10 drives the threaded rod 8 to rotate, and the threaded rod 8 is threadedly matched with the slide rail 5, and moves downward under the push of the thread while rotating, and the moving threaded rod 8 squeezes the elastic spring 9 to make the elastic spring 9 shrink and deform, and the deformed elastic spring 9 is filled with elastic potential energy, which increases the elastic force on the clamping block 7 and reduces the stroke of the clamping block 7 in the slide rail 5, so that the clamping block 7 can clamp a plate with a smaller thickness. After the adjustment is completed, the buckle 14 is rotated to clamp The buckle 14 clamps the limit rod 13 corresponding to the current position, restricting the movement of the sleeve 4, so that the elastic spring 9 maintains the current state to provide a stable elastic force for the clamping block 7. If a thicker plate needs to be clamped, the buckle 14 is flipped to move it away from the limit rod 13, and the limit between the sleeve 4 and the fixed rod 3 is released. At this time, the slide bar 11 is reset under the elastic force of the elastic member, and the limit on the gear 10 is released. At the same time, the elastic force of the elastic spring 9 lifts the threaded rod 8, restores the stroke of the clamping block 7 on the surface of the slide rail 5, and restores the elastic spring 9 to its original state, so as to clamp the thicker plate. By controlling the deformation degree of the elastic spring 9, the stroke and elastic force of the clamping block 7 are changed, and plates of various thicknesses can be effectively clamped. There is no need to replace the clamp separately. The operation is convenient and the work efficiency is improved. When the cutting is completed, the knob 18 is turned, and the knob 18 drives the rotating rod 16 to rotate. The rotating rotating rod 16 drives the arc blocks 17 at both ends to move. When the arc block 17 moves, the arc surface of the surface squeezes the slide rod 6 to move the slide rod 6. The moving slide rod 6 drives the clamping block 7 to move away from the plate, thereby releasing the clamping of the plate, making it convenient for the staff to take out the cut plate for use.

[0028] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
