[0003] After searching, a Chinese patent with announcement number CN218135020U discloses a corrosion-resistant alloy blade, including a main body plate, four first mounting holes for installation are opened at the lower end of the main body plate, and an installation cavity is opened at the upper end of the main body plate, blades are slidably connected on both sides of the installation cavity, and a pushing component for pushing the blade to be extended and retracted in the installation cavity is provided in the middle position of the installation cavity; through the setting of the pushing component, the blade can be extended and retracted during use, and the blade can be put into the installation cavity or pushed out of the installation cavity during use, which can prevent people from being cut by the blade when touching their hands.

[0004] The blade in this patent is rotationally connected between a rotating shaft and one end of a connecting rod, and the other end of the connecting rod is also rotationally connected to a driving column through a rotating shaft. Such a connection will cause the force on the entire blade to be transmitted through the shaft of the rotating shaft during actual use. The shaft in this patent is extremely small, so that the shaft will be loaded heavily after repeated use. When the force is too great, the shaft will be damaged and cannot be effectively replaced. Utility Model Content

[0007] As a preferred solution of the utility model, the front bottom end of the push block is symmetrically fixed with plug rods on both sides, the top of the inside of the blade is symmetrically provided with plug holes, the plug holes and the plug rods are movably connected, and after the blade is installed, the top of the blade fits against the bottom of the push block close to the elastic part.

[0008] As a preferred solution of the utility model, the elastic member is slidably connected to the inside of the slide groove.

[0009] As a preferred solution of the utility model, both sides of the top wall of the storage cavity and both sides of the top of the blade are fixedly connected with return springs, and limiting columns are installed between the return springs.

[0010] As a preferred solution of the utility model, mounting holes are provided at the four inner corners of the mounting plate.

[0011] As a preferred solution of the utility model, the rear wall of the storage cavity is provided with an avoidance groove for the push block to be inserted.

[0012] Compared with the prior art, the utility model has the following beneficial effects: the utility model inserts the insertion rod through the arranged insertion hole, and when the blade needs to be replaced, the old blade can be removed, and after installation, the insertion rod can resist the blade, and the recessed surface at the lower end of the elastic part can also resist the blade, which can apply resistance to the blade and improve the stability and firmness of the blade cutting. At the same time, the threaded block can push the two elastic clamping plates of the elastic part to both sides when it moves forward on the outside of the threaded rod, so that the elastic part is stuck in the inside of the fixed groove, further improving the firmness of the blade.

DETAILED DESCRIPTION

[0022] 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.

[0023] See also Figures 1 to 8 The utility model provides a technical solution: an alloy blade, including a main body plate 1 and a mounting plate 2 mounted on the right end of the main body plate 1, mounting holes 3 are provided at the four corners of the mounting plate 2, and the mounting plate 2 can be connected to other power equipment through the four mounting holes 3, a storage cavity 4 is provided inside the main body plate 1, a blade 5 is slidably connected inside the storage cavity 4, the blade 5 is made of tungsten steel, and the blade 5 can be stored in the storage cavity 4 when not in use, a push block 7 is detachably connected to the top of the blade 5, the push block 7 slides inside the storage cavity 4, and an elastic member 9 is fixedly connected to the front of the push block 7, the elastic member One square end of 9 can slide with the slide groove 13 to limit the position of the push block 7. The two elastic card ends of the elastic member 9 will separate when the force is applied in the middle, and can just be stuck in the inside of the fixed groove 12. A threaded rod 10 is fixedly connected to the center of the front side of the elastic member 9, and a threaded block 11 is threadedly connected to the outer side of the threaded rod 10. The threaded block 11 moves forward on the outer side of the threaded rod 10 to push the two elastic card plates of the elastic member 9 to both sides. A slide groove 13 is provided on the front side of the main body plate 1, and the elastic member 9 and the internal sliding connection of the slide groove 13 are provided. Fixed grooves 12 cooperating with the elastic member 9 are provided on both sides of the upper and lower ends of the slide groove 13.

[0024] Among them, the two sides of the front bottom end of the push block 7 are symmetrically fixed with plug rods 8, and the top inside the blade 5 is symmetrically provided with holes 6. The holes 6 and the plug rods 8 are movably connected, and the holes 6 are inserted into the plug rods 8. When the blade 5 needs to be replaced, the old blade 5 can be removed, and after installation, the plug rods 8 can resist the blade 5. After the blade 5 is installed, the top of the blade 5 is in contact with the bottom of the push block 7 close to the side of the elastic member 9, and the concave surface of the lower end of the elastic member 9 can also resist the blade 5.

[0025] Among them, both sides of the top wall of the storage cavity 4 and both sides of the top of the blade 5 are fixedly connected with return springs 15, and limiting columns 14 are installed between the return springs 15. When the blade 5 is needed, the return spring 15 can drive the blade 5 to pop out quickly.

[0026] Among them, the rear wall of the storage cavity 4 is provided with an avoidance groove 16 for the push block 7 to be inserted. When the blade 5 needs to be replaced, the push block 7 slides to the lower end of the slide groove 13, and then the elastic member 9 is pushed backward to insert the push block 7 into the avoidance groove 16, which can facilitate the separation of the push block 7 from the blade 5.

[0027] Specifically, first rotate the threaded block 11 backward, the two elastic clips of the elastic member 9 disengage from the two fixed grooves 12 at the upper end, and then the blade 5 pops out downward under the push of the two limit columns 14, and at the same time the push block 7 drives the elastic member 9 to slide downward inside the slide groove 13. When the elastic member 9 slides to the two fixed grooves 12 at the lower end of the slide groove 13, the threaded block 11 is rotated forward again to make the two elastic clips of the elastic member 9 snap into the two fixed grooves 12 at the lower end, and the position of the blade 5 is fixed, which can be used by holding the mounting plate 2, and the mounting plate 2 can also be fixed to the equipment by bolts. When the blade 5 needs to be replaced, the elastic member 9 can be slid to the lowest end of the slide groove 13, and then the threaded rod 10 is pushed backward to make the push block 7 insert into the inside of the avoidance groove 16, and then the insertion rod 8 falls off from the inside of the socket 6, and the blade 5 can fall out from the bottom of the main plate 1, and the new blade 5 can be put in.
