A blanking groove 12 used in conjunction with the detection slide plate 29 is penetrated on the side of the bottom end of the detection frame 1 away from the electric telescopic rod 21. The setting and use of the blanking groove 12 can guide the remaining parts of the bolt 3 to be tested that falls into the detection frame 1 to avoid the accumulation of remaining parts inside the detection frame 1, and a symmetrically distributed first through groove 13 and a second through groove 14 are penetrated on the side of the top of the detection frame 1 close to the blanking groove 12.

[0030] By adopting the above technical solution, when in use, the electric telescopic rod 21 will push the T-shaped push plate 23 to move to the side away from the electric telescopic rod 21, thereby driving the corresponding two first racks 24 to move, and then cooperating with the use of the driving gear 26 to drive the second rack 27 to move in the opposite direction, and further cooperating with the use of the first L-shaped rod 25 and the second L-shaped rod 28 to drive the adjacent detection slide plate 29 to move in the opposite direction, so that the anti-slip performance of the bolt 3 to be tested can be tested. When the thrust reaches a certain value, the corresponding two bolts 3 to be tested will be broken, and then the user can calculate the anti-slip coefficient of the bolt 3 to be tested according to the thrust.

The setting and use of the first through hole 46 play a limiting and guiding role in the sliding adjustment of the movable sliding bar 42, and the end of the movable sliding bar 42 close to the detection frame 1 is fixedly connected to the limiting disc 43, and the side of the limiting disc 43 away from the detection frame 1 is fixedly installed with a first spring 44, the first spring 44 is movably sleeved on the movable sliding bar 42, and the end of the first spring 44 away from the detection frame 1 is fixedly connected to the side of the side sliding block 41 close to the limiting disc 43, and a limiting stopper 45 is fixedly installed between the ends of the adjacent movable sliding bars 42 away from the detection frame 1, and the opposite sides of the adjacent limiting stopper 45 can be movably contacted with the bolt 3 to be tested.

[0032] By adopting the above technical solution, when in use, the user can pull any pair of movable slide bars 42 in the adjacent limit mechanism 4 to the side away from the detection frame 1 according to the usage habits. At this time, the corresponding two movable slide bars 42 will drive the corresponding limit baffle 45 to move to the side away from the detection frame 1, and when the movable slide bar 42 moves up, it will drive the corresponding limit disc 43 to move to the side away from the detection frame 1, so as to squeeze the corresponding first spring 44. When the corresponding limit baffle 45 moves to the highest point, the user can insert any one of the bolts 3 to be tested into the corresponding two detection through-holes 210, and loosen the bolt 3 to be tested when one end of the bolt 3 to be tested is in contact with the other limit baffle 45, and then loosen the corresponding two movable slide bars 42, and then the first spring 44 will drive the corresponding limit disc 43 to reset, thereby driving the corresponding movable slide bar 42 to reset, and then driving the corresponding limit baffle 45 to reset.

[0033] The buffer mechanism 5 includes a Z-shaped slide plate 51 and a mounting vertical plate 52. The Z-shaped slide plate 51 is fixedly mounted on the detection slide plate 29 near the second L-shaped rod 28, and the Z-shaped slide plate 51 is symmetrically distributed. A second through hole 53 is penetrated through the end of the Z-shaped slide plate 51 away from the detection slide plate 29. A T-shaped slide column 54 is slidably inserted in the second through hole 53. A mounting disc 55 is fixedly connected to the end of the T-shaped slide column 54 away from the detection slide plate 29, and a second spring 56 is fixedly connected to the side of the mounting disc 55 near the detection slide plate 29. The second spring 56 is movably sleeved on the T-shaped slide column 54, and One end of the second spring 56 away from the mounting disc 55 is fixedly connected to the Z-shaped slide plate 51, the mounting vertical plate 52 is fixedly mounted on the top of the detection frame 1, and the mounting vertical plate 52 is distributed in a mirror image, a T-shaped rubber column 57 is fixedly inserted at one end of the mounting vertical plate 52 away from the detection frame 1, a third through hole 58 is penetrated through the end of the mounting vertical plate 52 away from the detection frame 1, and the T-shaped rubber column 57 is fixedly inserted in the third through hole 58, the setting and use of the third through hole 58 provides a guarantee for the stable installation of the T-shaped rubber column 57, and the T-shaped rubber column 57 can contact with the mounting disc 55.

[0034] By adopting the above technical solution, when in use, when the thrust reaches a certain value, the corresponding two bolts 3 to be tested will be broken, and the electric telescopic rod 21 will continue to push the T-shaped push plate 23 to move. During the subsequent pushing, the Z-shaped slide plate 51 will drive the T-shaped slide column 54 to move toward the side close to the mounting vertical plate 52, and when the mounting disc 55 contacts the corresponding T-shaped rubber column 57, it will squeeze the corresponding second spring 56, so as to generate a reverse thrust on the movement of the detection slide plate 29, thereby forming a buffer, and further avoiding the first L-shaped rod 25 and the second L-shaped rod 28 from colliding with the first through groove 13 and the second through groove 14 respectively to cause damage.

[0035] The protection mechanism 6 includes a return-shaped guide frame 61, which is fixedly mounted on the detection frame 1 and is symmetrically distributed. A symmetrically arranged sliding guide rod 62 is slidably inserted into the inner cavity of the return-shaped guide frame 61, and the opposite ends of the sliding guide rod 62 are fixedly connected to a protection frame 63. The protection frame 63 can be slidably sleeved on the outside of the detection frame 1, and the opposite sides of the protection frame 63 are provided with symmetrically arranged mounting recesses 64. A first magnet 65 is fixedly mounted in the mounting recess 64 on one protection frame 63, and a first magnet 65 is fixedly mounted in the mounting recess 64 on the other protection frame 63. A second magnet 66 is provided, and the second magnet 66 is magnetically attracted to the first magnet 65. A mounting groove 67 is provided through the top of the protective frame 63, and a transparent observation window 68 is fixedly inserted in the mounting groove 67. The setting and use of the transparent observation window 68 provides convenience for the user to observe the detection results of the bolt 3 to be tested at any time. The opposite sides of the protective frame 63 are fixedly connected with a U-shaped grip 69, and the outer wall of the U-shaped grip 69 is covered with a layer of anti-slip grooves. The setting and use of the U-shaped grip 69 provides convenience for the movement and adjustment of the protective frame 63, and the anti-slip grooves can increase friction and facilitate operation.

[0036] By adopting the above technical solution, when in use, the user can simultaneously pull the two U-shaped handles 69 to the side away from the detection frame 1, so that the two protective frames 63 can be driven to move backwards through the U-shaped handles 69. At this time, the first magnet 65 and the second magnet 66 will be separated, and the adjacent sliding guide rods 62 will move backwards along the inner wall of the corresponding circular guide frame 61. When the distance between the adjacent sliding guide rods 62 moves to the maximum, the user can stop pulling the U-shaped handle 69, and when the bolt 3 to be tested is placed, the protective frame 63 can be reset.

[0037] Working principle: When in use, the user can pull the two U-shaped grips 69 to the side away from the detection frame 1 at the same time, so that the two protection frames 63 can be driven to move backwards through the U-shaped grips 69. At this time, the first magnet 65 and the second magnet 66 will be separated, and the adjacent sliding guide rods 62 will move backwards along the inner wall of the corresponding return guide frame 61. When the distance between the adjacent sliding guide rods 62 moves to the maximum, the user can stop pulling the U-shaped grips 69;

[0038] Then, the user can pull any pair of movable slide bars 42 in the adjacent limiting mechanisms 4 toward the side away from the detection frame 1 according to the usage habits. At this time, the corresponding two movable slide bars 42 will drive the corresponding limiting disc 45 to move toward the side away from the detection frame 1, and when the movable slide bars 42 move up, the corresponding limiting disc 43 will be driven to move toward the side away from the detection frame 1, so as to squeeze the corresponding first spring 44. When the corresponding limiting disc 45 moves to the highest point, the user can insert any one of the bolts 3 to be tested into the corresponding two detection through holes 210, and release the bolt 3 to be tested when one end of the bolt 3 to be tested is in contact with the other limiting disc 45, and then release the corresponding two movable slide bars 42, and then the first spring 44 will drive the corresponding limiting disc 43 to reset, thereby driving the corresponding movable slide bar 42 to reset, and then driving the corresponding limiting disc 45 to reset;

[0039] Afterwards, the user can hold the two U-shaped grips 69 again and reset the protection frame 63, and then release the U-shaped grips 69 and open the electric telescopic rod 21 until the corresponding first magnet 65 and the second magnet 66 are in contact. At this time, the electric telescopic rod 21 will push the T-shaped push plate 23 to move to the side away from the electric telescopic rod 21, thereby driving the corresponding two first racks 24 to move, and then cooperating with the use of the driving gear 26 to drive the second rack 27 to move in the opposite direction, and further cooperating with the use of the first L-shaped rod 25 and the second L-shaped rod 28 to drive the adjacent detection slide plate 29 to move in the opposite direction, so that the anti-slip performance of the bolt 3 to be tested can be tested. When the thrust reaches a certain value, the corresponding two bolts 3 to be tested will be broken, and then the user can calculate the anti-slip coefficient of the bolt 3 to be tested according to the thrust;

[0040] At this time, the electric telescopic rod 21 will continue to push the T-shaped push plate 23 to move. During the subsequent pushing period, the Z-shaped slide plate 51 will drive the T-shaped slide column 54 to move toward the side close to the mounting vertical plate 52, and when the mounting disc 55 contacts the corresponding T-shaped rubber column 57, it will squeeze the corresponding second spring 56, thereby generating a reverse thrust on the movement of the detection slide plate 29, thereby forming a buffer, and further preventing the first L-shaped rod 25 and the second L-shaped rod 28 from respectively colliding with the first through groove 13 and the second through groove 14 to cause damage.

[0041] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
