[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Unless otherwise specified, the technical means used in the implementation examples are conventional means well known to those skilled in the art.

[0027] refer to Figures 1-6 This utility model discloses a positioning device for a bimetallic washer nail, including a positioning sleeve 1. The positioning sleeve has an inner hole 5 extending through both ends. One end of the nail tube 2 from the nail gun is inserted into the positioning sleeve 1 and fixed by a bolt 9. A positioning sliding body 3 with a "T"-shaped cross-section is provided inside the positioning sleeve 1, near the end of the nail tube 2 extending into the positioning sleeve 1. The vertical part of the positioning sliding body 3 extends out of the positioning sleeve 1, and a spring 4 is fitted onto the vertical part of the positioning sliding body 3 inside the positioning sleeve 1. In use, the nail is inserted into the positioning sleeve 1, and the positioning sliding body 3, under the elastic force of the spring 4, presses against the nail to achieve the purpose of positioning the nail. During firing, the nail moves, thus completing the fastening operation.

[0028] Furthermore, the inner hole 5 of the positioning sleeve 1 is stepped, and a movable groove 6 is provided at the bottom of the small-diameter section of the positioning sleeve 1. The outward-facing side of the movable groove 6 is set as an opening. In one embodiment, the length of the movable groove is equal to the length of the small-diameter section. The positioning sliding body 3 is disposed in the movable groove 6, and the top surface of the positioning sliding body extends out of the top surface of the movable groove. That is, the width of the positioning sliding body 3 is less than or equal to the width of the movable groove 6, so that the top surface of the positioning sliding body can be partially located in the inner hole. Thus, after the nail is inserted into the inner hole, the positioning sliding body can press against the nail under the action of the spring. One end of the nail tube 2 is inserted into the large-diameter section of the positioning sleeve 1. At the same time, the opening of the nail tube abuts against the platform at the connection between the large-diameter section and the small-diameter section of the positioning sleeve 1, thereby increasing the stability of the nail tube inserted into the positioning sleeve.

[0029] Furthermore, to secure the nail tube within the positioning sleeve, an annular groove 7 is provided on the outer wall of the end of the nail tube 2 that is inserted into the positioning sleeve 1. The annular groove runs along the circumference of the nail tube. A screw hole 8 is provided through the bottom of the positioning sleeve 1, and a screw 9 is installed in the screw hole 8, extending into the annular groove 7. Preferably, the opening of the nail tube abuts against the step of the inner hole. The screw is preferably a flat-head screw, a countersunk hexagonal socket head cap screw, etc., but a bolt can also be used as needed. Its main function is to pass through the screw hole, allowing one end to extend into the annular groove, thereby restricting the nail tube and preventing it from falling out of the positioning sleeve.

[0030] Furthermore, the vertical part of the positioning slider 3 extends out of the movable groove 6 through the bottom of the movable groove 6 and is provided with an open retaining ring 10. The open retaining ring prevents the positioning slider from leaving the movable groove, and at the same time, it does not affect the positioning slider's up and down movement along its vertical part under the action of the spring.

[0031] Further reference Figure 4 , Figure 6 As shown, the top surface of the outward-facing side of the horizontal part of the positioning sliding body 3 is an inclined surface 11, so that the nail is inserted into the positioning sleeve and pressed against the top surface of the positioning sliding body.

[0032] Furthermore, refer to Figure 7 The diagram illustrates the insertion direction of the nail into the entire positioning device. The nail includes a shank 12, on which two trumpet-shaped metal washers 13 are sequentially fitted and fixed. The open ends of the metal washers 13 face the tip of the shank 12. The outer diameter of the shank 12 is smaller than the inner diameter of the nail tube 2, allowing the end portion of the shank to insert into the nail tube during nail insertion. The metal washers 13 are adapted to the small-diameter section of the inner hole 5, enabling successful insertion of the nail into the positioning sleeve and allowing the metal washers to contact the top surface of the positioning sliding body, applying a downward force. The inclined surface 11 further facilitates insertion of the nail into the positioning sleeve. The outer diameter of the metal washers 13 is larger than the inner diameter of the nail tube 2, preventing the metal washers from extending into the nail tube.

[0033] When using this utility model, according to Figure 7 As shown, the nail is inserted, and the positioning slider, under the action of the spring, holds the nail in place. During firing, the nail moves outward, thus completing the fastening process. The nail tube and nail gun disclosed in this utility model are connected by a threaded connection. Figure 3 In one embodiment, a nail gun with 6.8×11mm or 6.8×18mm nail cartridges can be used. During operation, only the nail tube needs to be replaced. It has a wide range of applications, improves work efficiency, and reduces costs.
