And a rubber layer can be provided between the positioning block 7 and the clamping block 8 to improve the positioning effect of the cable. Furthermore, a power source 6 for driving the measuring seat 5 to slide is installed on the adjusting seat 3.

[0032] Reference Figure 1 and Figure 3 , a sliding seat 9 is installed on the lower surface of the adjustment seat 3, and the sliding seat 9 extends in the arc groove 4. A limit member 10 is installed on the sliding seat 9, and the limit member 10 can be used to position the sliding seat 9 so that the sliding seat 9 cannot slide in the arc groove 4, thereby positioning the adjustment seat 3. Further, the limit member 10 and the clamping block 8 can be linked together. When the clamping block 8 is installed on the positioning block 7 to position the cable, the limit member 10 can position the sliding seat 9. When the clamping block 8 is removed from the positioning block 7, the limit member 10 can release the positioning of the sliding seat 9, so that the position of the adjustment seat 3 can be adjusted.
[0033] Reference Figure 1 and Figure 4 The two side walls of the sliding seat 9 are symmetrically provided with an accommodation cavity 16, and the limiting member 10 includes a locking seat 101 slidably installed in the accommodation cavity 16. A clearance groove 34 is provided on the inner wall of the arc groove 4, and the locking seat 101 extends in the clearance groove 34, so that the sliding seat 9 is not easy to be separated from the arc groove 4. A sliding column 17 is fixed on the locking seat 101, and a sliding groove 18 is provided on the inner wall of the accommodation cavity 16. The sliding column 17 is slidably inserted in the sliding groove 18, so that the locking seat 101 can slide in the accommodation cavity 16. The locking seat 101 is also equipped with a first elastic member 14, which is a spring, and the spring is sleeved on the outer wall of the sliding column 17, one end of the spring abuts against the side wall of the locking seat 101, and the other end abuts against the inner wall of the accommodation cavity 16. The locking seat 101 is provided with first teeth 11 at intervals on one side of the locking seat 101 facing the inner wall of the arc groove 4, and the second teeth 12 are evenly arranged on the inner wall of the clearance groove 34. When the first teeth 11 and the second teeth 12 are tightly engaged with each other, the sliding seat 9 can be positioned.
[0034] Reference Figure 4 and Figure 5 , an extrusion piece 15 is provided on the upper surface of the adjustment seat 3. Figure 3 A driving rod 13 is provided on the lower surface of the clamping block 8. When the clamping block 8 is installed on the positioning block 7, the driving rod 13 passes through the positioning block 7 and the measuring seat 5, and extends downward to cooperate with the extrusion piece 15, so that the locking seat 101 slides out of the accommodating cavity 16, the first teeth 11 and the second teeth 12 are tightly engaged and the first elastic member 14 is stretched at this time.
[0035] A long groove 19 is provided on the upper surface of the adjustment seat 3, and the extrusion piece 15 is installed in the long groove 19, and the lower end of the driving rod 13 can extend into the long groove 19. The extrusion piece 15 includes an extrusion strip 151 slidably installed in the long groove 19 and an extrusion column 152 fixed to the lower surface of the extrusion strip 151. Two driving rods 13 are symmetrically arranged on both sides of the clamping block 8, and the extrusion piece 15 and the driving rod 13 are arranged correspondingly. A second elastic piece 20 is installed between the lower surface of the extrusion strip 151 and the inner bottom surface of the long groove 19, and the second elastic piece 20 is a spring. The extrusion column 152 extends downward through the adjustment seat 3 and can extend into the accommodating cavity 16. When the clamping block 8 is installed on the positioning block 7, the driving rod 13 can squeeze the extrusion strip 151 to move downward. The side of the locking seat 101 close to the sliding column 17 is provided with an inclined guide surface structure, so that when the squeezing column 152 moves downward, the squeezing column 152 can abut against the side wall of the locking seat 101 and push the locking seat 101 to slide. After the clamping block 8 is disassembled, the second elastic member 20 drives the squeezing bar 151 to reset upward, and the locking seat 101 is reset back to the accommodating cavity 16, thereby unlocking the sliding seat 9.
[0036] In a further embodiment, referring to Figure 3 , the side walls of the positioning block 7 are symmetrically fixed with extension blocks 21, and the side walls of the clamping block 8 are provided with convex seats 22. A through rod 23 is passed through the convex seat 22, and a resistance block 24 is fixed to the upper end of the through rod 23, and a threaded hole 25 is opened on the extension block 21. The through rod 23 passes through the convex seat 22 and is threadedly connected to the threaded hole 25, so that the clamping block 8 is installed on the positioning block 7.
[0037] Reference Figure 3 and Figure 5When the clamping block 8 is mounted on the positioning block 7, the driving rod 13 extends into the long slot 19, and the lower end of the driving rod 13 abuts against the upper surface of the extrusion strip 151, and at this time the second elastic member 20 is compressed, and the second elastic member 20 provides a force for the extrusion strip 151 to move upward. Therefore, the friction between the driving rod 13 and the extrusion strip 151 is relatively large, which is easy to cause errors in the test results during the tension test. In order to overcome this problem, a pushing assembly 26 is installed on the side wall of the adjustment seat 3, and a trigger member 27 is installed at the lower end of the extension block 21. When the through rod 23 is threadedly connected to the extension block 21, the trigger member 27 can drive the pushing assembly 26 to move, so that the pushing assembly 26 drives the extrusion strip 151 to continue to move downward for a certain displacement, so that the extrusion strip 151 and the lower end of the driving rod 13 are separated, thereby reducing the friction force on the measuring seat 5 when sliding.
[0038] Reference Figure 3 and Figure 5 The pushing assembly 26 includes a rotating rod 261 rotatably connected to the side wall of the adjusting seat 3 and a pushing rod 262 slidably connected to the side wall of the adjusting seat 3. There is a certain gap between the rotating rod 261 and the pushing rod 262. A third elastic member 28 is installed between the pushing rod 262 and the adjusting seat 3. An abutting rod 263 is fixed on the pushing rod 262, and the abutting rod 263 slides through the side wall of the adjusting seat 3 and can extend into the long groove 19. The third elastic member 28 is a spring, which is sleeved on the side wall of the abutting rod 263 and one end of the spring is connected to the side wall of the pushing rod 262, and the other end abuts against the side wall of the adjusting seat 3. The side wall of the extrusion strip 151 is provided with an abutting groove 29. When the driving rod 13 pushes the extrusion strip 151 downward, the abutting groove 29 is slightly higher than the position of the end of the abutting rod 263. The side wall of the rotating rod 261 is provided with an arc block 35. The trigger member 27 cooperates with the rotating rod 261 and drives the rotating rod 261 to rotate, so that the arc block 35 abuts against the push rod 262 and pushes the push rod 262 to slide into the abutment groove 29, so that the abutment rod 263 can be inserted into the abutment groove 29, and then the extrusion bar 151 continues to move downward for a certain displacement. Then the driving rod 13 and the extrusion bar 151 are separated from each other. One end of the abutment rod 263 close to the abutment groove 29 is set as an arc structure, which is conducive to the insertion of the abutment rod 263 into the abutment groove 29.
[0039] Reference Figure 3 and Figure 6The trigger member 27 includes a trigger bar 271 that is slidably disposed through the extension block 21. The trigger bar 271 is a square bar structure, and the lower end of the trigger bar 271 passes through the lower end of the extension block 21. A fourth elastic member 30 is installed on the outer wall of one end of the trigger bar 271 in the threaded hole 25. The fourth elastic member 30 is a spring, and one end of the spring is connected to the upper end of the trigger bar 271, and the other end abuts against the inner bottom surface of the threaded hole 25. A rack portion 272 is fixedly connected to the lower end of the trigger bar 271, and a tooth bar 31 is provided on the side wall of the rotating rod 261, so that the cross section of the rotating rod 261 is a gear-like structure. The rack portion 272 and the tooth bar 31 are meshed. When the through rod 23 is threadedly connected to the threaded hole 25, it can push the trigger bar 271 to move downward, and the fourth elastic member 30 is compressed. At the same time, the rotating rod 261 can rotate, so that the arc block pushes the push rod 262 to move, and the third elastic member 28 is compressed. When the penetration rod 23 is disengaged from the threaded hole 25 , the fourth elastic member 30 drives the trigger bar 271 to move upward, and the rotating rod 261 rotates and resets, that is, the arc block 35 and the pushing rod 262 are disengaged, and the pushing rod 262 is reset.
[0040] The implementation principle of the wire and cable detection device for construction engineering of the present application is as follows: the clamping block 8 is installed on the positioning block 7, so that the lower end of the driving rod 13 pushes the extrusion bar 151 to move downward, that is, the locking seat 101 can be pressed against the inner wall of the arc groove 4. When the clamping block 8 and the positioning block 7 are connected, the through rod 23 pushes the trigger bar 271 to slide downward, so that the rotating rod 261 rotates, and drives the pushing rod 262 to slide, so that the abutment rod 263 is inserted into the abutment groove 29, and then the extrusion bar 151 moves downward by a certain displacement, and the surfaces of the driving rod 13 and the extrusion bar 151 are separated, thereby reducing the friction during the test.
[0041] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
