[0005] The cam is secured to the base with a spring which is secured on the base's upper edge and is designed to engage with the base at the other end of the cam.

[0006] Preferred technical solution 1: the diameter of the movable hole is smaller than the diameter of the movable groove, the connecting shaft matches the movable hole, the connecting block matches the movable groove, the two ends of the spring respectively abut against the inner side wall of the movable groove and the surface of the connecting block, and the diameter of the spring is larger than the diameter of the movable hole.

[0007] Preferred technical solution two: a groove is provided on the surface of the connecting shaft, a protrusion is fixedly connected to the surface of the groove, an inclined surface is provided at one end of the protrusion, the positions of the protrusion and the groove match the positions of the empty slot, and the protrusion and the groove are against the ball.

[0008] Preferred technical solution three: the diameter of the empty groove is smaller than the diameter of the ball, and a part of the ball can move inside the empty groove.

[0009] Preferred technical solution four: the diameter of the through groove is larger than the diameter of the through hole, the stepped core shaft matches the through hole, a limiting sleeve is fixedly sleeved on the surface of the stepped core shaft, and the diameter of the limiting sleeve is larger than the diameter of the through hole.

[0010] Preferred technical solution five: the main body, the stepped core shaft and the plug are all made of Teflon, the quick-release base and the quick-release connecting rod are all made of SUS, and the ball is made of CCr15.

[0011] Compared with the prior art, the utility model provides a blade holder quick-release inspection fixture with the following beneficial effects: when in use, the blade holder product is put on the quick-release base, and then the plug is driven to rotate by rotating the step core shaft, so that the step core shaft is moved by the action of the external thread and the internal thread, and the connecting block of the quick-release connecting rod is pushed to make the ball slide from the groove to the protrusion, so that the ball extends more from the inside of the empty groove, thereby performing installation and fixation inspection on the blade holder product, and the ball can be used to detect whether the inner groove of the blade holder product has any missing processing, which is convenient and fast. When the inspection is completed, the step core shaft is rotated in the opposite direction to release the tightness on the connecting block, so that it retracts to its original position under the elastic force of the spring, and the blade holder product can be quickly disassembled, which is simple and convenient.

DETAILED DESCRIPTION

[0022] See also Figure 1-9 ,

[0023] Embodiment 1: A quick-release inspection fixture for a blade holder includes a main body 1, a quick-release base 2, a stepped core shaft 3, a ball bearing 12, and a tool holder product 19. A through hole 4 is provided inside the main body 1, the quick-release base 2 is installed at one end of the main body 1, and a through groove 5 is provided at the other end of the main body 1. The inner wall of the through groove 5 is provided with an internal thread, and a plug 6 is fixedly sleeved on the surface of the stepped core shaft 3. The surface of the plug 6 is provided with an external thread, and the stepped core shaft 3 is threadedly sleeved on the inside of the through groove 5 through the external thread on the surface of the plug 6. Two rings 7 are fixedly sleeved on the surface of the quick-release base 2, and the quick-release base 2 is clamped and installed at one end of the main body 1 through two rings 7. A movable hole 8 is provided at one end of the quick-release base 2, and a movable groove 9 is provided at the other end of the quick-release base 2. The movable hole 8 is connected to the movable groove 9. A quick-release connecting rod 10 is movably inserted into the interior of the quick-release base 2, and an empty groove 11 is provided on the surface of the quick-release base 2. The quick-release connecting rod 10 includes a connecting block 13 and a connecting shaft 14, and a spring 15 is sleeved on the surface of the connecting shaft 14.

[0024] Embodiment 2: The difference between this embodiment and embodiment 1 is that the diameter of the movable hole 8 is smaller than the diameter of the movable groove 9, the connecting shaft 14 matches the movable hole 8, the connecting block 13 matches the movable groove 9, and the two ends of the spring 15 are respectively against the inner side wall of the movable groove 9 and the surface of the connecting block 13. The diameter of the spring 15 is larger than the diameter of the movable hole 8. The elastic force of the spring 15 facilitates the connection block 13 and the connecting shaft 14 to move and return to their original positions.

[0025] Embodiment 3: The difference between this embodiment and embodiment 1 is that a groove 16 is provided on the surface of the connecting shaft 14, and a protrusion 17 is fixedly connected to the surface of the groove 16. One end of the protrusion 17 is provided with a slope. The positions of the protrusion 17 and the groove 16 match the position of the empty slot 11. The protrusion 17 and the groove 16 are against the ball 12. The movement of the connecting shaft 14 can drive the ball 12 to extend from or retract into the inside of the empty slot 11.

[0026] Embodiment 4: The difference between this embodiment and embodiment 1 is that the diameter of the slot 11 is smaller than the diameter of the ball 12 , and a part of the ball 12 can move inside the slot 11 to prevent the ball 12 from falling out of the slot 11 .

[0027] Example 5: The difference between this example and Example 1 is that the diameter of the through groove 5 is larger than the diameter of the through hole 4, the step core shaft 3 matches the through hole 4, and the surface of the step core shaft 3 is fixedly sleeved with a limiting sleeve 18, and the diameter of the limiting sleeve 18 is larger than the diameter of the through hole 4, which makes it convenient to move the step core shaft 3 by rotating it.

[0028] Example 6: The difference between this example and Example 1 is that the main body 1, the stepped core shaft 3 and the plug 6 are all made of Teflon, the quick-release base 2 and the quick-release connecting rod 10 are all made of SUS304, and the ball 12 is made of CCr15. The materials of each component are restricted to make it more durable.

[0029] To sum up, when using the blade holder quick-release inspection fixture, the blade holder product 19 is put on the quick-release base 2, and then the plug 6 is driven to rotate by rotating the step core shaft 3, so that the step core shaft 3 is moved by the action of the external thread and the internal thread, and the connecting block 13 of the quick-release connecting rod 10 is pushed, so that the ball 12 slides from the groove 16 to the protrusion 17, so that the ball 12 extends more from the inside of the empty groove 11, thereby performing installation and fixation inspection on the blade holder product 19, and the ball 12 can be used to detect whether the inner groove of the blade holder product 19 has been missed. It is convenient and quick. When the inspection is completed, the connection block 13 is released by rotating the step core shaft 3 in the opposite direction, so that it retracts to its original position under the elastic force of the spring 15, and the blade holder product 19 can be quickly disassembled, which is simple and convenient.
