At least three second arc-shaped plates opposite to the first arc-shaped plates are fixed on the inner wall of the placement groove. Fixing seats are fixed at all four corners of the main body.

[0005] Preferably, the fixing component includes a lead screw, with movable blocks threaded to both ends of the outer surface of the lead screw, a movable plate fixed to one side of the first arc-shaped plate, and connecting rods movably connected to both ends of the movable blocks and the movable plate.

[0006] Preferably, the main body has a guide groove inside for placing the lead screw, and the outer surface of the moving block is slidably connected to the inner wall of the guide groove, which guides the movement of the moving block.

[0007] Preferably, one end of the movable block is fixed with a first bearing seat that is rotatably connected to one end of the connecting rod, and one end of the movable plate is fixed with a second bearing seat that is rotatably connected to the other end of the connecting rod, so that the connecting rod can rotate during movement. One end of the lead screw is fixed with a rotating handle for convenience and speed.

[0008] Preferably, the top of the fixing base has a threaded hole, which facilitates fixing the device to the ground or wall with bolts.

[0009] Preferably, the first arc-shaped plate and the second arc-shaped plate are fixed with rubber pads on the inward side, which protects the surface of the blasting lead and increases the friction between the blasting lead and the rubber pads, so that the blasting lead is fixed more firmly.

[0010] Preferably, the threads on the two sides of the lead screw are opposite in rotation direction, so that the rotation of the lead screw drives the two moving blocks to move inward or outward at the same time.

[0011] The beneficial effects of the utility model are:

[0012] 1. Through the cooperative action of the fixing assembly, the first arc-shaped plate and the second arc-shaped plate, the device can uniformly apply clamping force, ensure that the blasting lead is fixed firmly during blasting operation, avoid displacement of the blasting lead due to vibration or external force, and thus ensure the accuracy and safety of the blasting operation. 2. The device adopts the design of driving the lead screw by rotating the handle, so that the operator only needs to rotate the handle to realize clamping and loosening of the blasting lead, greatly reduces the complicated operation of the traditional fixing mode (such as tape binding and iron wire winding), and significantly improves the work efficiency.

[0013] 3. The first arc-shaped plate and the second arc-shaped plate are provided with rubber pads on the inner walls, which can provide sufficient friction to prevent the blasting lead from sliding, and can also avoid scratching of the insulating layer of the blasting lead, effectively reducing the safety hazards such as short circuit and electric leakage.
