Tubular dynamometer detection device

The utility model relates to the technical field of measuring instruments, and discloses a tubular dynamometer detection device which comprises a base, a vertical column fixedly connected to the middle of the top end of the base, a limiting hole formed in the vertical column, a screw rod movably connected between the upper side and the lower side of an inner cavity of the limiting hole, and a limiting block spirally sleeved on the outer side of the screw rod. The limiting blocks are movably connected into the limiting holes. According to the utility model, the pressing plate, the threaded rod, the bottom plate, the test spring, the nut and the measuring scale are arranged, the test spring sleeves the outer side of the threaded rod, then the nut is screwed to make the top of the test spring contact with the bottom of the pressing plate, no force is generated, and then the original length of the test spring is measured by the measuring scale. Then, after the pressing plate moves downwards to enable the bottom p
