The utility model provides a side hanging type laser pipe cutting machine which comprises a pipe cutting machine body and a front material receiving assembly arranged at the front end of the pipe cutting machine body, and the pipe cutting machine body is provided with a front clamping assembly and a rear clamping assembly which can clamp a pipe to move horizontally. The front material receiving assembly comprises a base and a supporting plate capable of moving up and down to be connected with the base. The side, close to the front clamping assembly, of the supporting plate is provided with a turnover part capable of being turned over downwards. A plurality of first hinges are arranged between the supporting plate and the folding part, a first air cylinder is arranged at the bottom of the supporting plate, and a piston rod of the first air cylinder is connected with the folding part. The front end of the pipe is effectively supported through the front material receiving assembly, the long pipe is prevented from drooping, and the cutting precision and the machining quality are improved. The supporting plate can be adjusted up and down to adapt to pipes of different sizes, and the stability of machining precision is guaranteed. Due to the design of the turnover part, when the front clamping assembly moves forwards, the front clamping assembly can be driven by the air cylinder to turn over and avoid, and normal cutting of the cutting head is ensured.

The utility model discloses a kind of reversible paper cutter, it is related to printer paper cutting technical field, including mounting bracket, the upper end transverse of mounting bracket is equipped with cutting platform, the upper end one side of mounting bracket is equipped with the knife rest that can be moved along cutting platform transverse reciprocating, two limiting hooks for locking main shaft are rotatably arranged on the side wall of the two sides of adjusting hole;When the knife rest moves from one end of cutting platform to the other end, it will enter the guide gap of another guide seat from the guide gap of one guide seat, while entering the guide gap, the guide inclined plane can open one limiting hook, and the limiting boss is used to push the main shaft of blade to switch from one limiting hook to another limiting hook.The utility model blade is from left to right or from right to left, and it is one-time cutting whole process when passing through cutting platform, improve paper cutting efficiency, and when cutting paper single time, the cutting path that blade can cut completely can completely cover the paper to be cut, ensure that cutting is completely cut single time.
