The utility model includes a splitting knife body and a mounting block. The mounting block is arranged on the top of the splitting knife body, and a limiting device is arranged between the outer surface of the splitting knife body and the inner wall of the mounting block. When the utility model uses a bonding machine and a splitting knife body to weld circuits on electronic components, it is usually necessary to select a splitting knife body of a matching size according to the size of the welded component, and then clip it into the inner wall of the mounting block on the binding machine, so that the card block on the splitting knife body is clipped into the card groove on the inside of the mounting block, and then the bolt is screwed into the first threaded hole on the mounting block so that it is screwed into the second threaded hole on the splitting knife body, so that splitting knife bodies of different sizes can be fixed and limited in the inner wall of the mounting block, so that the corresponding mounting block does not need to be replaced to fix and limit splitting knife bodies of different sizes.

[0004] Some ceramic splitting knives are often fixed in a mounting block, and bolts are provided in the mounting block. A threaded hole is opened on the ceramic splitting knives, and the ceramic splitting knives are fixed by threaded connection. However, in actual operation, considering that the splitting knives are made of ceramic materials, it is difficult to open threaded holes on the ceramic splitting knives and production is inconvenient. In addition, the ceramic splitting knives are not easy to replace by fixing with bolts, and the practicality is low. Utility Model Content

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] Reference Figure 1-6 A wear-resistant ceramic cleaver comprises a mounting seat 1 and a ceramic cleaver 2, wherein the ceramic cleaver 2 is arranged in the mounting seat 1, and a rotating seat 3 is rotatably connected to the bottom thereof, a stopper 4 which can abut against the bottom of the ceramic cleaver 2 passes through and is rotatably connected to the center point of the rotating seat 3, a clamping assembly 5 for fixing the ceramic cleaver 2 is arranged in the mounting seat 1, and an adjusting assembly 6 which can rotate the rotating seat 3 is arranged at the other end of the stopper 4.

[0023] It is worth mentioning that the ceramic cleaver 2 can abut against the abutment rod 4 when it slides to a certain position in the mounting seat 1. The advantage is that the length of the top of the abutment rod 4 is below the top of the claw 53, thus ensuring that the annular groove 21 can align with the claw 53 for easy clamping after the ceramic cleaver 2 reaches the position.

[0024] In addition, the ceramic splitting cutter 2 can be made of zirconium oxide, silicon nitride, boron carbide, cubic boron nitride, aluminum oxide, silicon carbide and other materials to improve wear resistance.

[0025] Furthermore, a ring groove 21 and a limiting groove 22 are formed at the bottom of the ceramic splitting knife 2 , and a limiting block 41 is provided at one end of the support rod 4 , and the limiting block 41 can be inserted into the limiting groove 22 .

[0026] Furthermore, the clamping assembly 5 includes a fixed seat 11 provided in the mounting seat 1 and located outside the rotating seat 3, a disc 51 is fixedly installed at one end of the rotating seat 3, the disc 51 is rotatably connected to the support rod 4, and a plurality of step portions 52 are opened on its outer circle, and a plurality of claws 53 are rotatably connected to the periphery of the fixed seat 11.

[0027] In more detail, a protrusion 54 is provided at the top of the fixing seat 11 next to the claw 53, and a first spring 55 is fixedly connected between the protrusion 54 and the side of the claw 53. The top of the claw 53 can be clamped into the annular groove 21 to fix the ceramic chopping knife 2. A round rod 56 is provided at the bottom of the claw 53. The round rod 56 is slidably connected to the fixing seat 11, and the other end thereof is in contact with the step portion 52.

[0028] The detailed process is that under the elastic support of the first spring 55, the claw 53 is normally in an open state, and then the disc 51 is driven to rotate through the rotating seat 3, so that the round rod 56 slides on the step portion 52, and when it reaches the highest point of the step portion 52, it pushes the bottom of the claw 53 and then the top of the claw 53 is clamped to the ceramic chopping knife 2.

[0029] It should be noted that the inner bottom surface of the mounting seat 1 is located between the fixed seat 11 and the rotating seat 3, that is, a positioning bead is fixedly installed below the disc 51, and a slot is opened at the bottom of the disc 51. The positioning bead can be snapped into the slot to fix the disc 51. The disc 51 cannot rotate at will, which can prevent the claw 53 from opening and closing freely.

[0030] In general, the adjustment assembly 6 includes a groove 61 opened on the side of the mounting seat 1, a swivel 62 is rotatably connected in the groove 61, a knob 63 is rotatably connected to one end of the support rod 4, and a second spring 64 is fixedly connected between the swivel 62 and the knob 63.

[0031] Finally, a plurality of slots 65 are provided at one end of the rotating seat 3, and a block 66 is provided on one side of the knob 63 close to the rotating seat 3. The block 66 can be snapped into the slot 65 to rotate the rotating seat 3.

[0032] In more detail, the function of the second spring 64 is to disengage the block 66 from the slot 65 to prevent the rotating seat 3 from being rotated by accidentally touching the knob 63, and to utilize the rotatable function of the rotating ring 62 and the knob 63 to drive the rotating seat 3 to rotate by pressing the knob 63 in conjunction with the block 66.

[0033] Working method: When working, the ceramic splitting knife 2 is inserted into the mounting seat 1. When the limit groove 22 is clamped into the limit block 41, the knob 63 is pushed to make the clamping block 66 clamped into the clamping groove 65 and then the knob 63 is rotated. This can drive the rotating seat 3 and the disc 51 to rotate. When the positioning bead is clamped into the clamping groove, the rotation stops. Then the round rod 56 drives the claw 53 to clamp the clamping ring groove 21 and fix the ceramic splitting knife 2 under the action of the step portion 52.

[0034] 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 technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
