DETAILED DESCRIPTION

[0024] Example, by Figure 1-7 The utility model includes a base 1, two first templates 2 distributed left and right, and two second templates 11 distributed front and back, the first template 2 and the second template 11 are both located at the top of the base 1, and the second template 11 is located between the two first templates 2, a positioning mechanism is installed on the outside of the first template 2, an adjustment mechanism, two second sliding rods 16 distributed up and down, and two mounting plates 18 distributed left and right are installed on the outside of the second template 11, a plurality of extension mechanisms are connected through the inside of the mounting plate 18, two second sliding sleeves 19 distributed up and down are fixedly connected to the outside of the mounting plate 18, the second sliding rod 16 passes through the second sliding sleeve 19, and the second sliding rod 16 and the second sliding sleeve 19 are slidably connected, two fixing rods 17 are fixedly connected between the second template 11 and the second sliding rod 16, and the adjustment mechanism is located between the two mounting plates 18 and the two second sliding rods 16. The second sliding rod 16 is installed on the outside of the second template 11 through the fixing rod 17, and the mounting plate 18 is slidably connected to the outside of the second template 11 through the second sliding sleeve 19 and the second sliding rod 16.

[0025] The extension mechanism includes an extension template 20, which is located between the second template 11 and the mounting plate 18. A second threaded rod 21 is movably connected to the outer side of the extension template 20 through a bearing. The second threaded rod 21 penetrates the mounting plate 18, and the mounting plate 18 and the second threaded rod 21 are threadedly connected. A second rotating wheel 23 is fixedly connected to the end of the second threaded rod 21. Two guide rods 24 distributed up and down are fixedly connected to the outer side of the extension template 20. The second threaded rod 21 is located between the two guide rods 24. The guide rod 24 penetrates the mounting plate 18, and the mounting plate 18 and the guide rod 24 are slidably connected. The end of the guide rod 24 is fixedly connected to a limiting block 25. The outer end of the second threaded rod 21 is fixedly connected to two limiting rings 22, and the mounting plate 18 is located between the two limiting rings 22. When the extension mechanism is not in use, the extension plate 20 is as close to the mounting plate 18 as possible and is stored outside the second template 11 along with the mounting plate 18. When in use, a corresponding number of extension mechanisms can be selected and the extension plate 20 can be adjusted to be flush with the second template 11. During this period, the forward and backward movement of the extension plate 20 will be restricted by the two limit rings 22, and the problem of excessive forward and backward movement will not occur. The maximum movement position of the extension plate 20 is flush with the second template 11. The extension plate 20 increases the length of the second template 11 and can flexibly adapt to the spacing adjustment requirements of the two first templates.

[0026] The positioning mechanism includes a connecting seat 3, which is sleeved on the top of the base 1 and extends to the bottom of the base 1. The connecting seat 3 is fixedly connected to the outer bottom of the first template 2. A plurality of reinforcing plates 4 are fixedly connected at the angle between the first template 2 and the connecting seat 3. A fastening screw 5 is respectively connected through both sides of the bottom of the connecting seat 3. The connecting seat 3 and the fastening screw 5 are connected by threads. The end of the fastening screw 5 is movably connected to a top block 7, and the top block 7 abuts against the bottom of the base 1. The positioning mechanism can support and install the first template 2 on the base 1, and it can be moved and fixed.

[0027] A first slide bar 9 is installed on both the front and rear sides of the base 1, and a first slide sleeve 8 is fixedly connected to both sides of the connection seat 3. The first slide bar 9 passes through the first slide sleeve 8, and the first slide sleeve 8 is slidably connected to the first slide bar 9. When the positioning mechanism drives the first template 2 to move, it mainly relies on the first slide sleeve 8 to slide on the first slide bar 9, which can play a role of directional sliding limit.

[0028] The adjustment mechanism includes a fixing plate 14, which is fixedly connected to the top of the base 1. A first threaded rod 13 is connected through the fixing plate 14. The first threaded rod 13 and the fixing plate 14 are connected by threads. The end of the first threaded rod 13 close to the second template 11 is movably connected to the outer side of the second template 11 through a bearing. A U-shaped plate 12 is fixedly connected to the center of the outer side of the second template 11. The first threaded rod 13 passes through the U-shaped plate 12. The end of the first threaded rod 13 away from the second template 11 is fixedly connected to the first rotating wheel 15. The adjustment mechanism can adjust the distance between the two second templates 11. A hole is opened on the U-shaped seat 12, and the first threaded rod 13 can just pass through it. The U-shaped seat 12 can improve the stability between the first threaded rod 13 and the second template 11, and it is not easy to tilt.

[0029] The bottom of the base 1 is fixedly connected with a plurality of support seats 6, which are composed of a horizontal plate and a plurality of vertical plates. The vertical plates are fixedly connected between the base 1 and the horizontal plate. The support seats 6 can support the base 1 to prevent the positioning mechanism from being interfered by the ground during operation.

[0030] Working principle:

[0031] When the distance between the two second templates 11 needs to be adjusted, the first threaded rod 13 only needs to be rotated by the first rotating wheel 15. Since the first threaded rod 13 and the fixing plate 14 are threadedly connected, the second template 11 can be driven to move closer to or away from the fixing plate 14 when the fixing plate 14 rotates, thereby adjusting the distance between the two second templates 11.

[0032] When the distance between the two first templates 2 needs to be adjusted, in order to form an integral closed loop between the second template 11 and the first template 2, the distance between the two first templates 2 can be determined first, but the position of the first template 2 is not adjusted temporarily, and then the two mounting plates 18 outside the second template 11 are moved away from each other, and the length of the second template 11 is increased as required. During operation, the second threaded rod 21 can be rotated by the second rotating wheel 23. Since the second threaded rod 21 and the mounting plate 18 are threadedly connected, the second threaded rod 21 can push the extension template 20 away from the mounting plate 18 when it rotates. Since the extension template 20 is no longer located outside the second template 11 at this time, the extension template 20 can be moved to a state flush with the second template 11, and when the extension template 20 is flush with the second template 11, the limiting ring 22 on the second threaded rod 21 located outside the mounting plate 18 will also hit the mounting plate 18, so that the second threaded rod 21 and the extension template 20 can no longer move further, and a corresponding number of extension mechanisms are added as required, and the extension template 20 in the extension mechanism can increase the length of the second template 11;

[0033] When the length formed by the second template 11 and the extended template 20 reaches the spacing requirement of the two first templates 2, loosen the fastening screws 5 in the positioning mechanism so that the top block 7 no longer abuts against the bottom of the base 1. At this time, the first template 2 and the positioning mechanism can slide and move on the base 1 through the first sliding sleeve 8 and the first sliding rod 9 until the two first templates 2 clamp the second template 11 and the extended template 20 in the middle, and then tighten the fastening screws 5 again so that the top block 7 abuts against the bottom of the base 1 so that the first template 2 can no longer move. At this time, the spacing adjustment of the two first templates 2 and the two second templates 11 is completed.
