[0026] Reference Figure 1-Figure 3 , is an embodiment of the utility model, providing a disc blade that is easy to install, comprising:

[0027] The main body 100 includes a blade body 101. A mounting hole is axially opened in the middle of the blade body 101 and matched with a blade shaft 102. The blade shaft 102 passes through the mounting hole. A retaining plate 103 is fixedly sleeved on the outer side of the blade shaft 102. The blade body 101 is against the retaining plate 103. Two sets of sliding cavities 101b are symmetrically opened inside the blade body 101.

[0028] The clamping mechanism 200 is provided with two groups in cooperation with the two groups of sliding cavities 101b, and includes a sliding block 201, the sliding block 201 is slidably arranged in the sliding cavity 101b, a clamping block 202 is fixedly connected to the side of the sliding block 201 facing away from the other group of sliding cavities 101b, a through hole is provided at the position of the blade shaft 102 facing the clamping block 202, the clamping block 202 passes through the through hole, and a clamping groove 101a is provided at the position of the blade body 101 facing the clamping block 202, the clamping block 202 is inserted into the card slot 101a, and a return spring 203 is arranged on the side of the sliding block 201 facing away from the card slot 202. The two ends of the return spring 203 are respectively in contact with the groove wall of the sliding cavity 101b and the sliding block 201. A sliding hole 101c connected to the sliding cavity 101b is provided at the end of the knife shaft 102 facing the sliding cavity 101b. A connecting block 204 is fixedly connected to the side of the sliding block 201 close to the sliding hole 101c, and the connecting block 204 passes through the sliding hole 101c.

[0029] Among them, the blocking block 202 is wedge-shaped, and the main body 100 also includes two groups of positioning columns 104. The two groups of positioning columns 104 are fixedly connected to the side of the abutment 103 close to the blade body 101. Positions of the blade body 101 facing the two groups of positioning columns 104 are provided with positioning holes that match the positioning columns 104. The two groups of positioning columns 104 are respectively inserted into the two groups of positioning holes. The two groups of positioning columns 104 are used to further improve the installation stability of the blade body 101. The two groups of positioning columns 104 are symmetrically arranged to ensure the positioning effect. The edges of the two groups of positioning columns 104 are provided with chamfers, and the chamfers are used to facilitate the insertion of the positioning columns 104 into the positioning holes.

[0030] It should be noted that the clamping mechanism 200 also includes a toggle block 205, which is fixedly connected to the side of the connecting block 204 facing away from the sliding block 201. The toggle block 205 is used to facilitate pushing the connecting block 204. The toggle block 205 is made of stainless steel material, and the sliding block 201 and the clamping block 202 are both made of stainless steel material. The stainless steel material is corrosion-resistant and is beneficial to ensuring the service life of the device. The surface of the toggle block 205 is rough, and the rough surface can increase friction and avoid slipping during operation.

[0031] Working principle: when installing the blade body 101, the blade body 101 is inserted into the blade shaft 102, the two groups of positioning holes are opposite to the two groups of positioning columns 104, the blade body 101 is pressed, and the blade body 101 squeezes the two groups of card blocks 202. Since the card blocks 202 are wedge-shaped, the extrusion of the blade body 101 will cause the two groups of card blocks 202 to respectively drive the two groups of sliding blocks 201 to move inward along the corresponding sliding cavity 101b, and the two groups of return springs 203 are compressed. Finally, the two groups of card blocks 202 are collected in the inner side of the sliding cavity 101b, and the blade body 101 is continued to be pressed down. When the blade body 101 is against the plate 103, the two groups of card blocks 202 are respectively opposite to the two groups of card slots 101a, the two groups of return springs 203 rebound, and the two groups of card blocks 202 are respectively inserted into the two groups of card slots 101a, and the installation of the blade body 101 is completed;

[0032] When disassembling the blade body 101, push the two groups of toggle blocks 205 inward, and the two groups of toggle blocks 205 respectively drive the two groups of sliding blocks 201 to move inward along the corresponding sliding cavity 101b through the two groups of connecting blocks 204, and the two groups of sliding blocks 201 respectively drive the two groups of clamping blocks 202 into the corresponding sliding cavity 101b. At this time, the two groups of clamping blocks 202 no longer clamp the blade body 101, and the blade body 101 can be directly taken out to complete the disassembly.

[0033] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
