[0032] The shock absorbing assembly includes a support plate 7, two shock absorbing frames 8 are arranged on the top of the support plate 7, a telescopic rod 10 is arranged on the bottom of the shock absorbing frame 8, a spring 11 is arranged on the outside of the telescopic rod 10, a connecting block 9 is installed on the top of the telescopic rod 10, a connecting rod 14 is arranged on the top of the connecting block 9, the connecting rod 14 is movably sleeved on the top of the shock absorbing frame 8, fixed blocks 12 are arranged on both sides of the connecting block 9, limiting grooves are arranged around the shock absorbing frame 8, and a shock absorber 13 is installed on one side of the fixing block 12 that passes through the limiting groove, and the bottom of the shock absorber 13 is fixedly connected to the surface of the support plate 7.

[0033] like Figure 5 As shown, the adjustment assembly includes a fixed plate 15 fixedly connected to the top of the connecting rod 14, the outer surface of the fixed plate 15 is provided with a slide groove 20, the internal movable sleeve of the slide groove 20 is provided with a bidirectional screw 16, the bidirectional screw 16 passes through one side of the fixed plate 15 and is installed with an axial rod 17, the external thread sleeve of the bidirectional screw 16 is provided with two movable seats 18, and the tops of the two movable seats 18 are both installed with clamps 19.

Different support heights of the template can be adjusted.

[0035] like Figure 5 As shown, a second threaded hole is provided inside the movable seat 18, and the movable seat 18 is threadedly matched with the bidirectional screw 16. The bidirectional screw 16 drives the movable seat 18 to move toward and away from each other, thereby driving the clamping plate 19 at the bottom to move, thereby adjusting the support width suitable for different templates.

[0036] like Figure 6 As shown, slide bars 22 are provided on both sides of the inner rod 4, and guide grooves 24 are provided on both sides of the sleeve 3, and the slide bars 22 are slidably connected with the guide grooves 24, so as to increase the stability when adjusting the lifting.

[0038] Working principle:

[0039] First, place the structure at the bottom of the template, and then adjust it according to the size and spacing of the template support. At this time, manually rotate the shaft 17 counterclockwise or clockwise, so that the shaft 17 drives the two moving seats 18 outside the bidirectional screw 16 to move toward or oppositely. In this process, the clamping plate 19 on the top of the moving seat 18 also moves synchronously. When the distance from the template is the same, stop rotating the shaft 17, and then turn on the external power supply, so that the output shaft of the motor 21 drives the screw 5 to rotate, and then the screw 5 drives the threaded inner rod 4 to move upward along the sleeve 3, and then during the movement, the slide bars 22 on both sides of the inner rod 4 follow the guide groove 24 Sliding increases its stability during movement and prevents the inner rod 4 from deflecting when moving inside the sleeve 3. At this time, the fixed plate 15 contacts the top template and supports it. When the support is generated due to external force, the overall supporting structure and the template vibrate, causing the template to squeeze the fixed plate 15, causing the fixed plate 15 to move downward, and then the connecting rod 14 at the bottom of the fixed plate 15 drives the connecting block 9 to squeeze the spring 11 and the shock absorber 13 fixed at the bottom of the fixed block 12 on both sides of the connecting block 9, and the external force is buffered under the joint action of the spring 11 and the shock absorber 13, thereby achieving the purpose of shock reduction and ensuring the stability of the template support.
