[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 of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] Example 1:

[0027] Please see Figure 1-4 This utility model provides a rebar tying machine, comprising:

[0028] The main body 1 and handle 2 of the strapping machine;

[0029] Battery assembly 3 is located at the bottom of handle 2. A mounting groove is provided on one side of the upper end of the binding machine body 1, and the wire tether body 4 is provided in the mounting groove.

[0030] A threaded rod 5 is set in the mounting groove. The external threads on both sides of the threaded rod 5 are arranged in opposite directions. Adjusting blocks 6 are provided on both sides of the threaded rod 5. The bottom ends of the two adjusting blocks 6 are abutted against the bottom end of the mounting groove.

[0031] Two clamping plates 7 are respectively set on the upper end of two adjusting blocks 6, and the two clamping plates 7 are respectively located on both sides of the wire binding disc body 4;

[0032] Positioning plate 8 is set on the upper end of the two adjusting blocks 6, and the positioning plate 8 is located inside the main body 4 of the wire binding disc.

[0033] Specifically, such as Figure 2 As shown, the main body 4 of the wire binding tray is provided with mounting shafts 9 on both sides. The two clamping plates 7 are provided with mounting grooves that are adapted to the mounting shafts 9 on opposite sides. The two mounting shafts 9 are located in the two mounting grooves respectively and are rotatably connected to the side wall of the mounting groove. The two mounting shafts 9 can limit the position of the main body 4 of the wire binding tray without affecting the rotation of the main body 4 of the wire binding tray.

[0034] Specifically, such as Figure 2 As shown, each of the two clamping plates 7 has multiple spherical grooves on one side, and each of the multiple spherical grooves has a matching guide ball 10. One end of each of the multiple guide balls 10 extends to the outside and abuts against both sides of the wire spool body 4.

[0035] Through its design, by using multiple guide balls 10 that abut against both sides of the wire spool body 4, the position of the wire spool body 4 can be limited while ensuring that it can rotate smoothly.

[0036] Specifically, such as Figure 2 As shown, both adjusting blocks 6 are provided with threaded holes that are adapted to the threaded rod 5. The threaded rod 5 passes through the two threaded holes and is slidably connected to the side wall of the threaded hole. By rotating the threaded rod 5, the two adjusting blocks 6 can be moved relative to each other. One end of the threaded rod 5 passes through the mounting groove and extends to the outside, so the threaded rod 5 can be rotated from the outside.

[0037] See Figure 1-4 When the binding wire in the main body 4 of the wire tying machine is used up and the main body 4 of the wire tying machine needs to be replaced, firstly, the threaded rod 5 needs to be rotated. The threaded rod 5 will drive the adjusting blocks 6 on both sides to move relative to each other. The two adjusting blocks 6 will drive the two clamping plates 7 to move relative to each other. The two clamping plates 7 will separate from the mounting shafts 9 at both ends of the main body 4 of the wire tying machine, so that the main body 4 of the wire tying machine can be disassembled. Then, the replaced main body 4 of the wire tying machine can be installed in the mounting groove. By reversing the threaded rod 5, the main body 4 of the wire tying machine can be installed.

[0038] Example 2:

[0039] Please see Figure 1-4 This utility model provides a rebar tying machine, comprising:

[0040] The main body 1 and handle 2 of the strapping machine;

[0041] Battery assembly 3 is located at the bottom of handle 2. A mounting groove is provided on one side of the upper end of the binding machine body 1, and the wire tether body 4 is provided in the mounting groove.

[0042] A threaded rod 5 is set in the mounting groove. The external threads on both sides of the threaded rod 5 are arranged in opposite directions. Adjusting blocks 6 are provided on both sides of the threaded rod 5. The bottom ends of the two adjusting blocks 6 are abutted against the bottom end of the mounting groove.

[0043] Two clamping plates 7 are respectively set on the upper end of two adjusting blocks 6, and the two clamping plates 7 are respectively located on both sides of the wire binding disc body 4;

[0044] Positioning plate 8 is set on the upper end of the two adjusting blocks 6, and the positioning plate 8 is located inside the main body 4 of the wire binding disc.

[0045] Specifically, such as Figure 2 and Figure 4 As shown, each of the two adjusting blocks 6 has a limiting groove at its upper end, and each limiting groove is provided with a limiting rod 11. Each limiting rod 11 is fitted with a limiting plate 12 that is compatible with the limiting groove. The two limiting rods 11 can restrict the movement of the two limiting plates 12 respectively, preventing their position from shifting. Each of the two limiting plates 12 is rotatably connected to a connecting rod 13 at its upper end. The upper ends of the two connecting rods 13 are rotatably connected to the two sides of the bottom end of the positioning plate 8 respectively. The two limiting plates 12 can drive the positioning plate 8 to move up and down through the two connecting rods 13 respectively. Each of the two limiting rods 11 is fitted with a limiting spring 14 at its outer end. The two limiting springs 14 are arranged in opposite directions, and their two ends are respectively located on one side of the limiting plate 12 and the limiting groove. The two limiting springs 14 can restrict the position of the two limiting plates 12 respectively, thereby restricting the position of the positioning plate 8.

[0046] Specifically, such as Figure 1 and Figure 3 As shown, a positioning rod 15 is provided on one side of the bottom end of the positioning plate 8. The bottom end of the positioning rod 15 passes through the mounting groove and extends to the outside.

[0047] With its design, when the wire ties body 4 is installed, the positioning plate 8 will abut against the bottom end of the wire ties inside the wire ties body 4. As the wire ties are gradually used, the positioning plate 8 will gradually move to one side of the wire ties body 4, thereby driving the positioning rod 15 to move up and down, and the remaining status of the wire ties inside the wire ties body 4 can be conveniently displayed from the outside.

[0048] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
