[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Reference Figures 1 to 4 The utility model provides a nail fixing device in a nail shooter, comprising a nail tube 1, a retaining ring 14 is fixedly connected inside the nail tube 1, the outer side of the retaining ring 14 abuts against a bottom plate 8, a nail rod 3 is horizontally fixed on the outer side of the bottom plate 8, the bottom plate 8 is axially slidably connected to the inside of the nail tube 1, a gunpowder cartridge 15 is horizontally fixed to the rear side of the bottom plate 8, the gunpowder cartridge 15 is axially slidably sleeved in the retaining ring 14, a rubber block is inserted into the tip of the nail rod 3, the gunpowder cartridge 15 is fixed to the bottom plate 8 by an adhesive, two radially symmetrical countersunk holes 4 are radially penetrated on the outside of the nail tube 1, the two countersunk holes 4 are both connected to the inside of the nail tube 1, and an elastic component is respectively arranged in each countersunk hole 4;

[0022] Two mirror-symmetrical guide grooves 9 are horizontally and axially provided on the outer side of the bottom plate 8, and the guide blocks 2 and the elastic components are cross-distributed, and one guide block 2 is axially and slidably connected in each guide groove 9, and the two guide blocks 2 are fixed to the inner wall of the nail tube 1, and the ends are fixedly connected to the outside of the retaining ring 14;

[0023] The elastic component includes a support block 13 axially slidably connected in the countersunk hole 4, two radially symmetrical slide grooves 10 are axially provided on the inner wall of the countersunk hole 4, and one side of the two slide grooves 10 is connected to the large diameter end of the countersunk hole 4, and a slider 12 is slidably connected in each slide groove 10, and the two sliders 12 are respectively fixed on both sides of the support block 13, and a sphere 7 is fixedly connected to one side of the support block 13 close to the inner wall of the nail tube 1, and a blocking block 6 is threadedly connected to the large diameter end of the countersunk hole 4, and a cross groove 5 is provided on the outer side of the blocking block 6, and a spring 11 is horizontally provided in the countersunk hole 4 to abut between the support block 13 and the blocking block 6;

[0024] By arranging an elastic component in the nail tube 1 and installing the nail rod 3 in the nail tube 1 by using the guide block 2 and the guide groove 9, the nail rod 3 is positioned and installed, and no other accessories are needed to position the nail rod 3 in the nail tube 1, so that the connection between the nail rod 3 and the nail tube 1 is more convenient and quick;

[0025] Working principle: When in use, align the guide groove 9 on the bottom plate 8 with the guide block 2 on the nail tube 1 for installation, insert it into the nail tube 1, and insert the guide block 2 into the guide groove 9.
