[0021] In this embodiment, by Figure 1-3As shown, the utility model includes a lower clamping plate 1, an upper clamping plate 2 is slidably arranged on the lower clamping plate 1, and through slots 3 are provided on the upper clamping plate 2 and the lower clamping plate 1, a button 4 is slidably arranged in the through slot 3 of the upper clamping plate 2, a first spring 5 is fixed on the button 4, and the other end of the first spring 5 is fixed on the through slot 3 of the upper clamping plate 2, the upper clamping plate 2 is fixed to the lower clamping plate 1 through the button 4, and the button 4 can be inserted into the through slot 3 of the lower clamping plate 1, when the through slot 3 on the upper clamping plate 2 with the button 4 installed is When the centers of the through slots 3 opened on the lower clamping plate 1 are aligned, the first spring 5 in the through slots 3 of the upper clamping plate 2 will push the button 4 to move, so that one end of the button 4 is exposed through the through slots 3 of the lower clamping plate 1, and the other end is located in the through slots 3 of the upper clamping plate 2, so that the upper clamping plate 2 and the lower clamping plate 1 are fixed. When it is necessary to adjust the length of the upper clamping plate 2 exposed on the lower clamping plate 1, press the button 4 so that the button 4 does not pass through the through slots 3 of the lower clamping plate 1. At this time, the upper clamping plate 2 can move on the lower clamping plate 1, so as to adjust the exposed length. When the upper clamping plate 2 is installed with When the through groove 3 of the button 4 is cocentric with a through groove 3 on the lower clamping plate 1, the first spring 5 will push the button 4 again to fix the upper clamping plate 2 and the lower clamping plate 1. A threaded tube 6 is fixed on the upper clamping plate 2. A pressure rod 7 is threadedly connected to the threaded tube 6. A rotating rod 8 is slidably provided on the upper end of the pressure rod 7. A pressure head assembly 29 is threadedly installed on the lower end of the pressure rod 7. The pressure head assembly 29 can be a truncated cone block. A clamping assembly is provided on the lower clamping plate 1. A mating member that engages with the pressure rod 7 is slidably provided in the upper clamping plate 2. The threaded plate 9, the mating threaded plate 9 is installed on the adjustment assembly, and the adjustment assembly is installed on the upper clamping plate 2. When the threaded plate 9 moves toward the pressure rod 7, the pressure rod 7 is squeezed, so that the pressure rod 7 is meshed with the threaded plate 9 and the threaded tube 6 at the same time, the pressure rod 7 rotates, which can drive the pressure head assembly 29 to move. By controlling the rotation direction of the pressure rod 7, the pressure head assembly 29 can be controlled to rise or fall. By rotating the rod 8, the pressure rod 7 can be better rotated to align the force, and the objects can be clamped and fixed by the pressure head assembly 29 and the clamping assembly;

[0022] The upper clamping plate 2 is slidably arranged on the lower clamping plate 1, the button 4 is slidably arranged in the through slot 3, and the pressing rod 7 is slidably arranged with a rotating rod 8. The above sliding connections are all slidably arranged in the form of sliders and slide rails.

[0023] In this embodiment, by Figure 2-3As shown, a safety shield plate 10 is fixed on the lower clamping plate 1, and a plurality of pressing holes 11 arranged in a vertical direction are opened on the safety shield plate 10. The pressing holes 11 are cocentric with the through groove 3. The thickness of the safety shield plate 10 is greater than the length of the button 4 extending out of the through groove 3 on the lower clamping plate 1. The safety shield plate 10 is used to block the button 4, so that when the button 4 is accidentally hit, only the safety shield plate 10 will be hit, and the button 4 will not be hit, thereby preventing the button 4 from being pressed in, thereby releasing the fixed limit between the upper clamping plate 2 and the lower clamping plate 1, and avoiding instability of the clamped items. When a body part hits the safety shield plate 10, unless a sharp part presses the button 4 from the pressing hole 11 on the safety shield plate 10, otherwise, the flat pressing will only press the safety shield plate 10 and the button 4 cannot be pressed.

[0024] In this embodiment, by Figure 2 and Figure 4 As shown, the clamping assembly includes a support plate 12 fixed to the lower clamping plate 1, and two placement grooves 13 are provided on the support plate 12, and clamping plates 14 are slidably arranged in the two placement grooves 13, and the two clamping plates 14 are engaged with the double-headed threaded rod 15, and the thread directions at both ends of the double-headed threaded rod 15 are opposite. When the double-headed threaded rod 15 rotates, the two clamping plates 14 move toward each other, and the double-headed threaded rod 15 is fixed on the rotating block 28. A circular groove connected to the placement groove 13 is provided on the support plate 12, and the rotating block 28 can move up and down in the circular groove, but will not separate from the circular groove. A sliding groove 16 provided on the support plate 12 is provided between the two placement grooves 13, and the double-headed threaded rod 15 is located in the sliding groove. The two clamps 14 can be moved out of the placement slot 13 by manually moving the rotating block 28 upwards. The rotating block 28 drives the double-headed threaded rod 15 and the two clamps 14 to move upwards, so that the clamps 14 are moved out of the placement slot 13. When not in use, the clamps 14 can be put into the placement slot 13 and moved out when in use. Then the rotating block 28 is rotated to drive the double-headed threaded rod 15 to rotate, thereby driving the two clamps 14 to move. The clamps 14 are slidably arranged in the slide slot 16. The movement direction of the two clamps 14 is controlled by controlling the rotation direction of the rotating block 28. The two clamps 14 can move toward the direction of the pressure rod 7 at the same time to clamp the objects placed on the support plate 12, and can also move away from each other at the same time to release the limit of the objects on the support plate 12.

[0025] In this embodiment, by Figure 2 and Figure 4As shown, the support plate 12 is provided with a locking rod 17 by means of a slider and a slide rail for sliding, a locking plate 18 is fixed on the locking rod 17, a fourth spring 19 is fixed on the locking rod 17, and the other end of the fourth spring 19 is fixed on the support plate 12, and a locking groove 20 that cooperates with the locking plate 18 is opened on the rotating block 28. After the two clamping plates 14 are controlled by the rotating block 28 to clamp the article, the locking rod 17 is pulled away from the support plate 12, so that the locking rod 17 drives the locking plate 18 to move, and then the locking plate 18 and the locking plate on the rotating block 28 are aligned. The positioning grooves 20 are aligned in parallel, and then the locking plate 18 is pushed to embed into the locking grooves 20. The locking plate 18 is tightened by the fourth spring 19 to make the locking plate 18 contact with the locking grooves 20, thereby limiting and fixing the rotating block 28. At this time, the locking block cannot rotate, so that the clamping plate 14 cannot move, and the object is clamped and fixed. The object can also be fixed without using a clamping assembly. The object can be directly placed on the support plate 12 and clamped by lowering the pressure head assembly 29. When the rotating block 28 moves up to the maximum distance, the locking plate 18 can also cooperate with the locking groove 20.

[0026] In this embodiment, by Figure 2 and Figure 4-5 As shown, the adjustment assembly includes a positioning block 21 slidably arranged in the upper clamping plate 2, the threaded plate 9 is fixed on the positioning block 21, a positioning groove 22 is provided on the positioning block 21, a limiting block 23 is slidably arranged on the positioning groove 22, a second spring 24 is fixed on the limiting block 23, the other end of the second spring 24 is fixed in the positioning groove 22, a moving groove 25 is provided on the upper clamping plate 2, the positioning block 21 is slidably arranged on the moving groove 25, the positioning block 21 is fixed in the upper clamping plate 2 by a third spring 26, the limiting block 23 is attached to the side wall of the upper clamping plate 2, an L-shaped groove 30 is provided on the upper clamping plate 2, and the L-shaped groove 30 is connected to the moving groove 25;

[0027] The limit block 23 is located on the positioning groove 22 and also on the L-shaped groove 30. The threaded plate 9 presses the pressure rod 7 so that the threaded plate 9 and the threaded tube 6 are engaged with the pressure rod 7. At this time, the rotation of the pressure rod 7 can drive the pressure head assembly 29 to rise and fall. When the pressure rod 7 needs to be raised and lowered quickly, the limit block 23 is moved upward so that the limit block 23 moves from the vertical groove of the L-shaped groove 30 on the upper clamping plate 2 to the junction of the horizontal groove and the vertical groove of the L-shaped groove 30, so that the limit block 23 can move laterally. At this time, the limit block 23 squeezes the second spring 24, and then moves the limit block 23 laterally so that the limit block 23 moves in the direction away from the pressure rod 7. The limit block 23 drives the positioning block 21 to move in the direction away from the pressure rod 7 and squeezes the third spring 26. At this time, the positioning block 21 drives the threaded plate 9 to disengage from the pressure rod 7, and the pressure rod 7 does not mesh with the threaded plate 9 and the threaded tube 6 When the pressure rod 7 is closed, the pressure rod 7 can move upward or downward quickly. When the pressure rod 7 is moved quickly, the pressure rod 7 drives the pressure head assembly 29 to press against the object or move away from the object, the limit block 23 is released, and the limit block 23 is pushed by the third spring 26 to move the positioning block 21 in the direction close to the pressure rod 7. Then, when the limit block 23 reaches the junction of the L-groove horizontal groove and the vertical groove, the second spring 24 pushes the limit block 23 to move away from the rotating rod 8, thereby limiting the lateral movement. At this time, the threaded plate 9 and the threaded tube 6 are both engaged with the pressure rod 7, and the pressure rod 7 can only move by rotating. At the same time, the limit block 23 is pushed by the second spring 24, which can prevent the limit block 23 from floating up and down itself. At the same time, the L-shaped groove 30 limits the limit block 23 from moving horizontally, preventing the pressure rod 7 from disengaging from the cooperation of the threaded plate 9 and the threaded tube 6, thereby ensuring stable clamping of the object.

[0028] In this embodiment, by Figure 1-2 As shown, a force-bearing plate 27 is placed between the two clamping plates 14. The force-bearing plate 27 can be clamped by a clamping assembly to expand the force-bearing area of ​​the article and better clamp and fix the article.

[0029] When the utility model is used, first check whether it is necessary to install the force plate 27 to clamp the object. If necessary, fix the force plate 27 on the clamping assembly, then press the button 4 according to the length of the object to contact the limit of the upper clamping plate 2, adjust the exposed length of the upper clamping plate 2, then place the object on the force plate 27, then release the limit of the pressure rod 7 through the adjustment assembly, so that the pressure rod 7 quickly contacts the object, then limit the pressure rod 7 through the adjustment assembly, and then rotate the pressure rod 7 to clamp and fix the object.
