[0002] Materials often need to be cut during existing construction or mechanical processing, and a fixing fixture is indispensable for cutting materials. In order to facilitate the replacement and removal of materials, the existing cutting fixtures mostly clamp the materials horizontally. This method may cause the object to pop out from the top, endangering the risk of personal safety. In addition, this method of clamping objects horizontally generally only fixes one layer or a single object at a time, and the construction efficiency is low. Utility Model Content

[0003] The utility model aims to provide a clamp for concentrated cutting of multi-layer materials.

[0004] The utility model is realized by the following measures: a clamp for concentrated cutting of multi-layer materials, characterized in that it comprises a base, a vertical structure fixedly arranged at one end of the base, a screw fixedly arranged at the other end of the base, a clamp sleeved on the screw, and a nut arranged on the screw through a threaded connection;

[0005] The vertical structure is provided with a U-shaped groove opening toward the screw rod, and one end of the clamping plate close to the U-shaped groove is provided with a limiting rod inserted into the U-shaped groove;

[0006] The clamping plate is provided with a strip-shaped opening matched with the screw rod, the clamping plate reciprocates along the direction of the strip-shaped opening, and the limiting rod can extend into and out of the U-shaped groove;

[0007] A plurality of U-shaped grooves are arranged along the height direction of the vertical structure.

[0008] The limiting rod is a round rod, and a semicircular groove for placing the round rod is provided on the inner side of the bottom wall of the U-shaped groove. Due to the presence of the U-shaped groove and the strip-shaped opening, when the nut is loose, the limiting rod is easily moved out of the U-shaped groove, affecting the clamping effect. The limiting rod can be limited by the semicircular groove, and even if the nut is loose, it cannot be separated from the semicircular groove.

[0009] The vertical structure includes vertical plates symmetrically arranged on the base, the tops of the two vertical plates are connected by a top plate, and the U-shaped groove is arranged on the vertical plates.

[0010] The outer wall bottom of the base is symmetrically provided with a plurality of connecting plates, and mounting holes are reserved on the connecting plates. The connecting plates are generally welded to the base, and the reserved mounting holes are used to install ground anchors or expansion bolts to fix the base to the ground.

[0011] A boss is fixedly provided below the base, and a threaded hole cooperating with the screw is provided through the boss, so that the screw can be disassembled. The boss is located below the base and does not affect the normal placement of materials.

[0012] A mounting plate is fixedly arranged on the vertical structure and above the U-shaped groove, a spring pin facing the semicircular groove is arranged below the mounting plate, the round rod is placed in the semicircular groove, and the spring pin presses against the outer wall of the round rod.

[0013] The axis of the spring pin and the axis of the semicircular groove are in the same plane.

[0014] It is best to arrange a rubber pad under the clamping plate to protect the material.

[0015] The base comprises a bottom plate and side plates symmetrically arranged on both sides below the bottom plate.

[0016] The bottom plate is provided with a plurality of reinforcing plates connecting the two side plates.

[0017] A gasket is arranged on the screw rod and below the nut.

[0018] The opening of the U-shaped groove and the inner diameter of the semicircular groove are slightly larger than the limiting rod, and the inner wall of the opening end of the U-shaped groove is provided with a chamfer to facilitate the installation of the limiting rod.

[0019] Method of use: insert the splint from above the screw, and when it reaches the U-shaped groove corresponding to the material height, move the splint in the direction of the U-shaped groove. Due to the existence of the strip-shaped opening, the splint is not restricted by the screw, and the limiting rod can enter the U-shaped groove and then fall into the semicircular groove. At this time, the lower section of the splint is against the material, and then put on the gasket and tighten the nut to fix it.

[0020] When there is a spring pin, the limit rod will lift the spring pin when entering the U-shaped groove and the semicircular groove. When the limit rod completely falls into the semicircular groove, the spring pin is reset. At this time, the bottom of the spring pin presses on the limit rod, thereby limiting the limit rod.

[0021] After the material is cut, the nut is loosened, the limiting rod is removed from the semicircular groove and the U-shaped groove, and the clamping plate is rotated with the screw as the rotating shaft to achieve the removal and replacement of the material. The structure is simple and easy to use.

[0022] In addition, when the material to be cut is long, multiple multi-layer material centralized cutting clamps can be used to achieve the cutting of the material.

[0023] The beneficial effects of the technical solution provided by the embodiment of the utility model are as follows: when cutting multiple layers of materials, the materials are clamped longitudinally by the base and the height-adjustable clamping plate, so that the multiple layers of materials can be cut simultaneously; due to the longitudinal clamping, it is not easy to warp up during the cutting process; one side of the clamping plate is directly placed in the groove, and the other side is fixed by a nut, which is easy to disassemble, and the material can be quickly removed and replaced.
