[0026] In one embodiment, a hollow groove 102 is provided inside the fixed sleeve 101, and limiting grooves 103 are provided on both sides of the inner wall of the hollow groove 102. One side of the fixed sleeve 101 is fixedly connected to one side of the internal threaded fixing block 104. The inner wall of the internal threaded fixing block 104 is threadedly connected to the outer wall of the locking bolt 105. The inner wall of the hollow groove 102 is movably connected to the outer wall of the extension rod 106. Both sides of the bottom of the extension rod 106 are fixedly connected to one side of the limiting slider 107. The outer wall of the limiting slider 107 is movably connected to the inner wall of the limiting groove 103. The outer wall of the locking bolt 105 is threadedly connected to the inner wall of the locking thread groove 108, and multiple groups of locking thread grooves 108 are evenly provided.

[0027] Specifically: according to needs, the locking bolt 105 is rotated so that the locking bolt 105 is away from the inside of the locking thread groove 108, and the extension rod 106 is moved so that the extension rod 106 moves inside the hollow groove 102, and at the same time drives the limiting slider 107 to move inside the limiting slide groove 103. When the extension rod 106 is extended to a suitable height, the locking bolt 105 is rotated so that the locking bolt 105 enters the inside of the locking thread groove 108 through the internal thread fixing block 104, thereby locking the extension rod 106. By adjusting the length between the fixed sleeve 101 and the extension rod 106, the overall height of the device can be adjusted.

[0028] In one embodiment, the top of the extension rod 106 is fixedly connected to the bottom of the fixed connecting block 201, a spherical groove 202 is provided at the top of the fixed connecting block 201, and the inner wall of the spherical groove 202 is movably connected to the outer wall of the spherical block 203, a groove 204 is provided on one side of the bottom of the spherical groove 202, and an inclined thread groove 205 is provided on one side of the groove 204, and the inner wall of the inclined thread groove 205 is connected to the thread of the fastening bolt 206, the outer wall of one end of the fastening bolt 206 is rotatably connected to the inner wall of one side of the extrusion block 207 through a bearing, and the outer wall of the extrusion block 207 is movably connected to the inner wall of the groove 204.

[0029] Specifically: the driving motor 302 is rotated according to demand, so that the driving motor 302 can be adjusted in angle through the spherical block 203. During the angle adjustment, the spherical block 203 moves inside the spherical groove 202. When adjusted to a suitable angle, the fastening bolt 206 is rotated to move the fastening bolt 206 inside the inclined thread groove 205, thereby driving the extrusion block 207 to move inside the groove 204, and at the same time, the outer wall of the spherical block 203 is squeezed, thereby locking the spherical block 203. The cooperation between the spherical block 203 and the spherical groove 202 facilitates the angle adjustment of the driving motor 302, making it easier for the movable chuck 309 to clamp the bolt to be tested.

[0030] In one embodiment, the top of the spherical block 203 is fixedly connected to the bottom of the motor frame 301, the top of the motor frame 301 is fixedly connected to the outer wall of the shell of the drive motor 302, and the output end of the drive motor 302 is fixedly connected to one side of the connecting frame 303 through a coupling.

[0031] Specifically: start the drive motor 302 to drive the bolt clamped by the movable clamp 309 to tighten the bolt, and check whether the bolt is tightened by observing whether the bolt rotates.

One side of the convex internal thread block 308 is fixedly connected to one side of the movable chuck 309.

[0033] Specifically: Place the movable chuck 309 on the crane beam bolt, turn the rotary knob 307 to drive the double-headed threaded screw 306 to rotate, and then drive the convex internal thread block 308 to move relative to the movable groove 304 and the inner wall of the movable groove 304, thereby driving the movable chuck 309 to move toward the outer wall of the bolt to clamp the bolt. The spacing is adjusted by moving the movable chuck 309, and at the same time, it is convenient to lock the bolts that need to be measured.

[0034] Working principle: according to the demand, the locking bolt 105 is rotated so that the locking bolt 105 is away from the inside of the locking thread groove 108, and the extension rod 106 is moved so that the extension rod 106 moves inside the hollow groove 102, and at the same time, the limiting slider 107 is driven to move inside the limiting slide groove 103. When the extension rod 106 is extended to a suitable height, the locking bolt 105 is rotated so that the locking bolt 105 enters the inside of the locking thread groove 108 through the internal thread fixing block 104, thereby locking the extension rod 106. Then, the driving motor 302 is rotated according to the demand so that the driving motor 302 is adjusted in angle through the spherical block 203. When the angle is adjusted, the spherical block 203 moves inside the spherical groove 202. When it is adjusted to a suitable angle Finally, the fastening bolt 206 is rotated to make the fastening bolt 206 move inside the inclined thread groove 205, thereby driving the extrusion block 207 to move inside the groove 204, and at the same time squeezing the outer wall of the spherical block 203, thereby locking the spherical block 203, and placing the movable clamp 309 on the crane beam bolt, turning the rotary knob 307 to drive the double-headed threaded screw 306 to rotate, thereby driving the convex internal thread block 308 to move relative to the moving groove 304 and the inner wall of the moving groove 304, thereby driving the movable clamp 309 to move toward the outer wall of the bolt to clamp the bolt, and starting the drive motor 302 to drive the bolt clamped by the movable clamp 309 to tighten the bolt, and by observing whether the bolt rotates, it can be checked whether the bolt is tightened.
