[0027] In the present device, at least three clamping parts 3 can slide relative to the inner wall of the mounting groove along the radial direction of the mounting groove and are evenly connected to the inner wall of the mounting groove, and the clamping parts 3 can be clamped with the dust cover 1 to limit the sliding of the dust cover 1 relative to the inner wall of the mounting groove, the rotating part 4 is connected to at least three clamping parts 3, and the rotating part 4 can be rotatably connected to the shearing machine body 2 relative to the shearing machine body 2, and is used to drive the three clamping parts 3 to slide relative to the inner wall of the mounting groove at the same time, so that the clamping parts 3 are released from the clamping connection with the dust cover 1 after sliding.

[0028] Compared with the prior art, at least three clamping parts 3 are provided to clamp the dust cover 1 inserted into the mounting groove, so that the dust cover 1 is stably clamped in the mounting groove by at least three clamping parts 3, and at the same time, the clamping part 3 and the dust cover 1 are released by rotating the rotating part 4 relative to the shearing machine body 2, so that the user can take the dust cover 1 out of the mounting groove, and the installation and disassembly are convenient, which can solve the technical problem in the prior art that the dust cover 1 is unstable in installation because the dust cover 1 is only connected to the clamping block through the top fixing block.

[0029] Furthermore, the shearing machine in the present device is a scissors-like structure, which uses shearing force to cut off the exhaust catalyst. Usually, the shearing machine is provided with a dust cover 1 to block dust. As the use time increases, a large amount of dust will be adsorbed on the surface of the protective cover, which requires the user to disassemble and clean the protective cover. The shearing machine and the dust cover 1 are common and easy-to-purchase equipment on the market. This is a conventional setting known to technicians in this field and will not be elaborated on. Reference can also be made to the Chinese utility model patent with application number: CN202021937931.1, entitled: A shearing device for exhaust catalyst recovery.

[0030] like Figure 5 , Figure 6 As shown, the clamping member 3 includes a clamping block 31 and an elastic portion 32 , a guide rod 33 , and at least one ball 34 .

[0032] The elastic portion 32 is connected to the clamping block 31 and is used to provide an elastic restoring force for the clamping block 31 to automatically return to its original position after sliding, so that the clamping block 31 is clamped tightly to the dust cover 1 .

[0033] Furthermore, the elastic part 32 here is a spring, a spring sheet and an elastic block that are common and purchased in the market. This is a conventional setting known to those skilled in the art and will not be described in detail.

[0034] As an implementation method, Figure 5 , Figure 6 As shown, the cross-sectional area of ​​the clamping block 31 decreases continuously in the direction approaching the opening end of the mounting groove.

[0035] The clamping block 31 is provided with an inclined surface. When the dust cover 1 is inserted into the installation groove, the user presses the dust cover 1 to squeeze the clamping block 31 through the dust cover 1, and the clamping block 31 is pushed into the sliding groove, thereby facilitating the use of the user.

[0036] As another implementation method, Figure 6 As shown, a guide groove is further provided on the inner wall of the bottom of the slide groove, one end of the guide rod 33 is slidably inserted in the guide groove, and the other end is connected to the clamping block 31 .

[0037] The cooperation between the guide rod 33 and the guide groove guides the sliding of the clamping block 31 .

[0038] As another implementation method, Figure 6As shown, the clamping block 31 is provided with at least one spherical groove on the inner wall of the slide slot, and the balls 34 are arranged one by one correspondingly to the spherical grooves, and the balls 34 roll inside the spherical grooves and abut against the inner wall of the slide slot.

[0039] The ball 34 is rotatably built into the spherical groove to reduce the friction force when the clamping block 31 slides relative to the sliding groove.

[0040] like Figures 3 to 5 As shown, the device further includes a fixing tube 5 and an elastic abutting ring 6.

[0041] The fixed cylinder 5 is sleeved in the mounting groove and fixedly connected to the shearing machine body 2 , and the axis of the inner hole of the fixed cylinder 5 is coaxially arranged with the axis of the mounting groove, and the rotating member 4 is rotatably connected to the fixed cylinder 5 .

[0042] The fixed cylinder 5 plays a connecting role in the rotation of the rotating ring 41.

[0043] As an implementation method, Figure 5 As shown, the elastic abutment ring 6 is connected to the bottom inner wall of the installation groove and abuts against the dust cover 1.

[0044] The elastic abutment block is connected to the bottom inner wall of the installation groove and is tightly abutted against the dust cover 1 , so as to improve the stability of the dust cover 1 connected to the shearing machine body 2 .

[0045] like Figures 2 to 4 As shown, the rotating member 4 includes a rotating ring 41 and at least three connecting ropes 42 .

[0046] The fixing tube 5 is provided with an external thread, the rotating ring 41 is provided with an internal thread, and the rotating ring 41 is threadedly connected to the fixing tube 5 and connected to at least three clamping members 3 .

[0047] The rotating ring 41 and the fixing tube 5 are connected by threads to achieve relative rotation.

[0048] As an implementation method, Figure 5 As shown, the shearing machine body 2 is also provided with at least three connecting grooves, which are arranged one by one corresponding to the guide grooves and are connected to the guide grooves, and the connecting grooves pass through the outer wall of the shearing machine body 2. One end of the connecting rope 42 is connected to the rotating ring 41, and the other end is connected to the guide rod 33.

[0049] By rotating the rotating ring 41 relative to the fixed tube 5, the connecting rope 42 is wound around the fixed tube 5 so that its length is reduced. As the length of the connecting rope 42 is shortened, the clamping block 31 slides into the sliding groove, releasing the clamping block 31 from the dust cover 1.

[0050] Furthermore, the connecting rope 42 in the present device is a common and purchased steel wire rope on the market, which is a conventional setting well known to those skilled in the art and will not be described in detail.

[0051] The utility model also provides an exhaust catalyst shearing machine, comprising: a shearing machine body 2, a dust cover 1, and a connecting device as described in any one of the above.

[0052] In the specific working process of the utility model, at least three clamping parts 3 can slide along the radial direction of the mounting groove relative to the inner wall of the mounting groove, and are evenly connected to the inner wall of the mounting groove, and the clamping parts 3 can be clamped with the dust cover 1 to limit the sliding of the dust cover 1 relative to the inner wall of the mounting groove, and the rotating part 4 is connected to the at least three clamping parts 3, and the rotating part 4 can be rotatably connected to the shearing machine body 2 relative to the shearing machine body 2, and is used to drive the three clamping parts 3 to slide relative to the inner wall of the mounting groove at the same time, so that the sliding clamping parts 3 are released from the clamping of the dust cover 1. Compared with the prior art, by setting at least three clamping parts 3 to be clamped with the dust cover 1 inserted into the mounting groove, the dust cover 1 is stably clamped in the mounting groove by at least three clamping parts 3, and by setting the rotating part 4 to rotate relative to the shearing machine body 2, the clamping part 3 and the dust cover 1 are released at the same time, which is convenient for the user to take out the dust cover 1 from the mounting groove, and convenient for installation and disassembly.

[0053] When in use, the user first inserts the dust cover 1 into the installation groove along the opening of the installation groove, and then the dust cover 1 abuts against the clamping piece 3. As the dust cover 1 is continuously pressed, the inclined surface of the clamping block 31 abuts against the dust cover 1, and the clamping block 31 slides into the sliding groove. Then, when the dust cover 1 abuts against the elastic abutting block, the clamping block 31 slides out of the sliding groove and is clamped with the dust cover 1. The dust cover 1 is stably installed and installed. Finally, when the user needs to replace the dust cover 1, the user rotates the rotating ring 41 so that the connecting rope 42 drives the clamping block 31 to separate from the dust cover 1, thereby releasing the restriction of the clamping block 31 on the dust cover 1, and the user can easily take the dust cover 1 out of the installation groove.

[0054] The device, through the above structure, can solve the technical problem in the prior art that the dust cover 1 is unstable in installation because the dust cover 1 is connected to the clamping block only through the fixing block at the top.

[0055] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by any technician familiar with the technical field within the technical scope disclosed in the present invention should be included in the protection scope of the present invention.
