The invention discloses a multifunctional drilling rig for a tunnel. The multifunctional drilling rig comprises a vehicle frame assembly, an operating table assembly, a variable amplitude mechanism, adrilling mast assembly, an engine system and a motor system; the drilling rig adopts a double-power system which comprises the engine system and the motor system; the operating table assembly is located on the vehicle frame assembly; and the drilling mast assembly adopts a feeding mode of a motor and a chain and is mounted on the vehicle frame assembly through the variable amplitude mechanism, the variable amplitude mechanism is provided with a rotating disc, the rotating disc can rotate, thus left-right rotating of the variable amplitude mechanism is achieved, and the drilling mast assemblyis driven to rotate leftwards and rightwards.

The invention relates to a use method of a linear cutting and positioning fixture. The use method includes the following steps that firstly, a positioning base is fixedly connected to an operating table through a square groove; secondly, a positioning hole of a workpiece is matched with a positioning screw rod; thirdly, the positioning screw rod is provided with a positioning nut so as to clamp the workpiece; fourthly, linear cutting is carried out on the workpiece through a through hole. The structure is simple, operation is easy and convenient, and machining precision is high.

The invention discloses an arc-shaped cutting stapler convenient for positioning. The arc-shaped cutting stapler comprises a stapler body, an arc-shaped cutting head and a supporting assembly. A fixed handle is arranged on the right side of the bottom of the stapler body. The arc-shaped cutting head is arranged on the left side of the stapler body. The arc-shaped cutting head is connected with an anvil head through a connecting block. The supporting assembly is installed below a fixed handle of the stapler body. A first supporting rod is connected with the bottom of a second supporting rod through a first connecting lug. The second supporting rod is connected with a third supporting rod through a second connecting lug. The bottom of the third supporting rod is rotationally connected with a clamping head. According to the arc-shaped cutting stapler convenient for positioning, the supporting assembly is arranged. The supporting assembly is internally connected with the first supporting rod, the second supporting rod and the third supporting rod by rotation to conveniently adjust an angle of the stapler body in use. Meanwhile, the supporting assembly can be clamped and fixed to a specified position of an operating table through the clamping head without being held in hands, thereby reducing burden on arms of a doctor.
