This utility model belongs to the field of trolley technology, and specifically relates to a trolley that facilitates straight-line travel. It includes a balance scooter and a trolley body, connected by a connecting frame. The connecting frame is detachably connected to the trolley body and rotatably connected to the balance scooter. The balance scooter has a positioning groove, and the connecting frame has a positioning element and an elastic element. The elastic element drives the positioning element to engage with the positioning groove, fixing the balance scooter and the connecting frame relatively, thus allowing the trolley to maintain straight-line travel or maintain a certain angle of rotation. Under external force, the positioning element can move relative to the positioning groove, allowing the balance scooter and the connecting frame to rotate relative to each other, thus enabling the trolley to turn flexibly. The purpose of this utility model is to provide a user-friendly trolley that facilitates straight-line travel.

The utility model provides a vertical metal band sawing machine, belongs to the technical field of vertical metal band sawing machines, and solves the problems of poor cutting surface and large deformation caused by flame cutting for automatically cutting a long iron plate into a small iron plate by a domestic vertical band sawing machine. The vertical metal band sawing machine comprises a base, a feeding lifting oil cylinder is fixed to the base, a feeding frame is fixed to the telescopic end of the feeding lifting oil cylinder, a feeding workbench is fixed to the feeding frame, a discharging frame is fixed to the base, a motor is fixed to the discharging frame, a discharging table is fixed to the discharging frame, and a plurality of discharging wheels are rotationally connected to the discharging table. The discharging wheel is fixedly connected with the output shaft end of the motor, a straight saw frame body is fixed to the base, a power distribution control box and an electric appliance box are fixed to the straight saw frame body, a movable guide arm is fixed to the straight saw frame body, and a saw belt is arranged on the guide arm. The metal cutting device has the advantages of being smooth in metal cutting face, small in deformation, easy and convenient to operate and the like.
