[0034] The utility model provides a clamping tool 100, which can be used to clamp a product 4 to be tested, and can realize pull-out testing in multiple directions by clamping once.

[0035] Specifically, Figure 1-4 As shown, the clamping tool 100 provided by the embodiment of the utility model specifically includes a base 1 and a clamping part 2, wherein the base 1 is provided with a first magnetic part; the clamping part 2 includes a first clamping block 21 and a second clamping block 22 which are adapted to be connected to form a receiving cavity, and the receiving cavity is used to clamp and fix the product 4 to be inspected; the first clamping block 21 is provided with a second magnetic part which is adapted to be magnetically attracted to the first magnetic part; wherein the first clamping block 21 is rotatably mounted on the base 1 through a magnetic connection between the first magnetic part and the second magnetic part.

[0036] Specifically, by providing a clamping portion 2 capable of clamping the product 4 to be detected, and providing it with a second magnetic portion that can be magnetically connected to the first magnetic portion on the base 1, the clamping portion 2 can be magnetically connected to the base 1 at any angle. In this way, when the direction of the product 4 to be detected needs to be adjusted, the connection angle between the clamping portion 2 and the base 1 can be directly adjusted without re-clamping the product 4 to be detected, thereby saving detection time and improving detection efficiency.

[0037] In one embodiment, a positioning hole 14 is provided on the mounting surface of the base 1; a positioning column 23 is provided on the side of the first clamping block 21 away from the second clamping block 22, and the positioning column 23 is adapted to the positioning hole 14. By providing the positioning hole 14 and the positioning column 23 that are adapted to be connected, the clamping part 2 can only rotate around the central axis of the positioning hole 14, so that it is easy to control the clamping position of the clamping part 2 and improve the position accuracy of the product 4 to be detected.

[0038] Specifically, the cross section of the positioning hole 14 is circular and can be a through hole or a blind hole. The diameter of the positioning column 23 is the same as that of the positioning hole 14, and the length of the positioning column 23 protruding from the first clamping block 21 is less than or equal to the axial length of the blind hole.

[0039] In one embodiment, a protrusion 15 is provided on the mounting surface of the base 1, and a plurality of positioning grooves 24 are provided on the side of the first clamping block 21. The first clamping block 21 can be rotated to match the positioning grooves 24 with the protrusion 15. By providing the positioning grooves 24 that can be matched with the protrusion 15, the connection between the base 1 and the clamping part 2 is improved, and the angle deflection between the two after the magnetic connection is avoided, and the clamping angle of the clamping part 2 can be accurately controlled and adjusted.

[0040] Specifically, the protrusion 15 is a strip block protruding from the base 1 and having a rectangular cross-section. The cross-sectional shape of the positioning groove 24 is the same as the cross-sectional shape of the protrusion 15, and the positions of the two correspond. In this way, when the clamping part 2 is rotated to an appropriate position, the protrusion 15 can be embedded in the positioning groove 24, thereby circumferentially limiting the base 1 and the clamping part 2.

[0041] In one embodiment, the central axis of the protrusion 15 passes through the center of the positioning hole 14 along the longitudinal direction of the positioning hole 14; the positioning grooves 24 are evenly divergently arranged along the circumference of the second magnetic attraction portion.

[0042] Specifically, one end of the positioning groove 24 extends to the positioning column 23, and the other end extends to the edge of the first clamping block 21, so that the positioning groove 24 is formed into a through groove. One end of the protrusion 15 extends to the positioning hole 14, and the other end extends to the end of the base 1, so that when the clamping part 2 is connected to the base 1, the protrusion 15 can be accommodated in the positioning groove 24.

[0043] The above arrangement of the present embodiment makes the structure of the first clamping block 21 simple, thus improving the stability between the base 1 and the clamping portion 2 .

[0044] In one embodiment, the number of the positioning grooves 24 is eight.

[0045] Specifically, there are 8 positioning grooves 24, and the angles between adjacent positioning grooves 24 are all 45 degrees, so that the pull-out test of the product to be tested in 48 directions can be achieved.

[0046] In one embodiment, the second magnetic attraction portion is embedded in the positioning column 23 , or the positioning column 23 is formed by the second magnetic attraction portion.

[0047] Specifically, when the second magnetic attraction portion is embedded in the positioning column 23, it can be formed integrally with the positioning column 23. Alternatively, the second magnetic attraction portion is formed into a cylindrical structure and serves as the positioning column 23 to fit the positioning hole 14.

[0048] In one embodiment, the first magnetic attraction portion is embedded in the base 1 .

[0049] Specifically, the first magnetic attraction portion can be arranged in a plate shape and buried in the bottom of the positioning hole 14 , or the first magnetic attraction portion can be arranged in a ring shape on the outer periphery of the positioning hole 14 .

[0050] In one embodiment, a receiving groove 25 is provided on the side of the first clamping block 21 relative to the second magnetic attraction portion, and a step hole 26 is provided on the first clamping block 21 . The large end of the step hole 26 cooperates with the receiving groove 25 to form a receiving cavity.

[0051] One side of the product 4 to be inspected abuts against the side of the receiving groove 25 , and the outer peripheral edge of the other side abuts against the step surface of the step hole 26 , so that it is received in the receiving cavity formed by the first clamping block 21 and the second clamping block 22 .

[0052] In one embodiment, a first screw hole is provided on the side of the first clamping block 21 relative to the second clamping block 22, and a second screw hole is provided on the second clamping block 22. The first clamping block 21 and the second clamping block 22 are connected by screws 3 inserted into the first screw hole and the second screw hole.

[0053] Specifically, the first screw hole is a blind hole with internal threads, and the second screw hole is a through hole, so that the screw hole passing through the second screw hole is screwed with the first screw hole to achieve the fixation of the first clamping block 21 and the second clamping block 22.

[0054] In one embodiment, the base 1 includes a bottom platform 12 and a mounting portion 11 erected on the bottom platform 12 , the first magnetic attraction portion is disposed on the mounting portion 11 , and the clamping portion 2 is connected to a side surface of the mounting portion 11 .

[0055] Specifically, the mounting portion 11 is plate-shaped and vertically supported on the base 12 by two legs 13, so that it can be connected to the clamping portion 2 through the side. The side of the mounting portion 11 used to connect with the clamping portion 2 is circular, rectangular or other polygonal, preferably, its side is rectangular.

[0056] The base 12 is used to support the mounting portion 11, the clamping portion 2 and the product to be detected 4 to prevent them from tipping over. Specifically, the base 12 may be a round table, a rectangular table or the like.
