[0007] Furthermore, the measuring rod is threadedly connected to the threaded rod via an internal thread, and a scale is provided on the surface of the measuring rod. When the threaded rod rotates counterclockwise, the measuring rod is driven to move inside the box body, and the scale on the surface of the measuring rod can be used to measure the rod.

[0008] Furthermore, the airbag is located at one end of the placement groove away from the abutment plate. The airbag is in an expanded state in the initial state. When the rod is inserted into the placement groove and the abutment plate is used to press the rod tightly, the airbag will be squeezed. The air pressure inside the squeezed airbag will enter the air pressure chamber to push the push rod to move upward.

[0009] Furthermore, the arc surface of the arc block faces the front end of the box body, and the depth of the groove is greater than the length of the arc block. When the arc surface of the arc block is squeezed, it will retract into the groove, and the arc block can be completely retracted into the groove.

[0010] Furthermore, the number of the limiting blocks is set to eight groups, and the eight groups of limiting blocks are arranged in a circular array on the surface of the threaded rod. The eight groups of limiting blocks in a circular array on the surface of the threaded rod can ensure that the arc block can contact the limiting block after the push block moves upward.

[0011] Furthermore, the buffer mechanism includes a slide groove and a slide rod, the slide groove is opened on the side of the abutment plate close to the box body, the slide rod penetrates the abutment plate and is slidably connected, the side of the slide rod is fixedly connected with a buffer plate, and the surface of the slide rod is sleeved with a buffer spring.

[0013] The utility model has the following beneficial effects:

[0014] 1. The utility model is provided with a rotation limiting mechanism, so that when the rod is inserted into the placement groove and the threaded rod is rotated counterclockwise to drive the abutment plate to press against the rod, the push block will be driven to move upward through the cooperation of components such as the airbag and the air pressure chamber. After the push block moves upward, the threaded rod can no longer rotate counterclockwise through the cooperation of components such as the arc block and the limiting block to prevent the occurrence of thread slippage, while the clockwise rotation will not be affected when the abutment plate leaves the rod.

[0015] 2. The utility model is provided with a buffer mechanism, so that when the rod is inserted into the placement slot and the threaded rod is rotated counterclockwise to drive the abutment plate to press against the rod, the buffer plate, buffer spring, slide rod and other components will cooperate to play a buffering role, preventing the abutment plate from being damaged by the impact caused by the rapid movement of the abutment plate and the contact with the rod.

[0016] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] The measuring rod 4 is threadedly connected to the threaded rod 2 via an internal thread, and a scale is provided on the surface of the measuring rod 4. When the threaded rod 2 rotates counterclockwise, the measuring rod 4 will be driven to move inside the box body 1. The scale on the surface of the measuring rod 4 can be used to measure the rod.

[0029] The airbag 72 is located at one end of the placement groove 6 away from the abutment plate 5. The airbag 72 is in an expanded state in the initial state. When the rod is inserted into the placement groove 6 and the abutment plate 5 is used to press the rod tightly, the airbag 72 will be squeezed. The air pressure inside the squeezed airbag 72 will enter the air pressure chamber 71 to push the push rod 73 to move upward.

[0030] The arc surface of the arc block 77 faces the front end of the box body 1, and the depth of the groove 75 is greater than the length of the arc block 77. When the arc surface of the arc block 77 is squeezed, it will retract into the groove 75, and the arc block 77 can be completely retracted into the groove 75.

[0031] The number of limiting blocks 78 is set to eight groups, and the eight groups of limiting blocks 78 are arranged in a circular array on the surface of the threaded rod 2. The eight groups of limiting blocks 78 are arranged in a circular array on the surface of the threaded rod 2 to ensure that the arc block 77 can contact the limiting block 78 after the push block 74 moves upward.

[0032] The buffer mechanism 8 includes a slide groove 81 and a slide rod 82. The slide groove 81 is opened on the side of the abutment plate 5 close to the box body 1. The slide rod 82 penetrates the abutment plate 5 and is slidably connected. The side of the slide rod 82 is fixedly connected with a buffer plate 83, and the surface of the slide rod 82 is sleeved with a buffer spring 84.

[0033] The buffer plate 83 is made of rubber material, and the opening size of the slide groove 81 is larger than the size of the buffer plate 83 . The buffer plate 83 made of rubber material has a certain elasticity, and the buffer plate 83 can enter the slide groove 81 .

[0034] A specific application of this embodiment is: insert the rod into the placement slot 6, and rotate the threaded rod 2 counterclockwise through the handle 3. The counterclockwise rotation of the threaded rod 2 will drive the measuring rod 4 to move left through the cooperation of the thread on it and the built-in thread of the measuring rod 4. The leftward movement of the measuring rod 4 will drive the abutment plate 5 to move left and press against the rod, and when the abutment plate 5 presses against the rod, the air bag 72 will be squeezed. The air pressure in the squeezed air bag 72 will enter the air pressure chamber 71 to push the push rod 73 to move upward. The upward movement of the push rod 73 will drive the push block 74 to move upward. The upward movement of the push block 74 will drive the arc block 77 to move upward. After the arc block 77 moves upward, when the threaded rod 2 is rotated counterclockwise, the limiting block 78 will conflict with the straight surface of the rear end of the arc block 77, making the threaded rod 2 unable to rotate counterclockwise, so as to prevent the measuring rod 4 from slipping after the abutment plate 5 presses against the rod and then rotates the threaded rod 2 counterclockwise. When the push plate 5 leaves the rod and no longer squeezes the airbag 72, the airbag 72 rebounds and the air pressure returns to the airbag 72, and the push rod 73 drives the push block 74 to move upward and restore. Before that, when the push plate 5 moves to the left and contacts the rod, the rod will contact the buffer plate 83, causing the buffer plate 83 to move to the right and enter the slide groove 81, and the buffer spring 84 will absorb the impact force and gradually tighten. The buffer plate 83, the buffer spring 84 and other components cooperate to play a buffering role, thereby preventing the push plate 5 from being damaged by the impact caused by the rapid movement of the push plate 5 and the contact with the rod.
