This utility model relates to the field of sports equipment technology, specifically to an easily adjustable starting sprinter, including a starting frame and an adjustment device. A base plate is fixedly connected to one side of the starting frame, and toe plates are slidably connected to both sides of the starting frame. The adjustment device is disposed on the surface of the starting frame and includes a strip sleeve fixedly connected to the surface of the starting frame. A slider is fixedly connected to one side of the toe plates, and a groove is provided on the side of the starting frame near the slider. The slider is slidably connected to the starting frame, and a fixing rod is fixedly connected to the upper surface of the slider. In this utility model, when the user exerts force with their legs to start running, the slider bears the main pressure, effectively reducing the stress on the telescopic rod. This greatly reduces the risk of damage to the cylinder and telescopic rod due to excessive starting impact, extends the service life of the electric equipment, reduces the frequency of equipment maintenance and replacement, and ensures the stability and reliability of the starting sprinter's adjustment function.

The utility model provides a kind of support structure for roll bending machine, the lower main shaft of roll bending machine and the head of roll bending machine are connected respectively;The support structure includes support body and support plate;Lower main shaft is rotatably connected with one end of support plate, and the other end of support plate is connected with support body;The end portion of support body away from support plate is adjustably connected with head;Support body is parallel with lower main shaft as support piece, and support plate is the connecting piece of lower main shaft and support body.The support structure of the utility model can effectively and stably support the lower main shaft of roll bending machine, solve the problem that the lower main shaft is inclined and then falls due to insufficient pulling force of existing pull rod structure, so as to ensure the bending processing precision of profile.The utility model also provides a kind of roll bending machine, which can stably roll the profile with large cross section or high strength, and the roll bending machine can also be suitable for bending processing of the profile into a circular shape.
