[0032] The adjusting member 202 moves inside the fixing sleeve 201 to adjust the position of the clamping member 203, thereby improving the firmness of the fixing member 103 on the outer side of the screw rod 101 to prevent the fixing member 103 from falling off to a limited extent, resetting the clamping member 203 by means of the spring 204, and limiting the position of the adjusting member 202 by means of the fixing rod 205.

[0033] Example 2 Reference Figure 2 , Figure 3 and Figure 4 , which is the second embodiment of the present invention, and this embodiment is based on the previous embodiment.

[0034] Specifically, the support member 102 includes a clamping sleeve 102a and an anti-skid pad 102b. The clamping sleeve 102a is disposed on the outer side of the screw rod 101, and the anti-skid pad 102b is fixed on the outer side of the clamping sleeve 102a.

[0035] The clamping sleeve 102a is symmetrically sleeved on the outside of the screw rod 101. The screw rod 101 is set on the template, and then the clamping sleeve 102a is pushed to clamp with the outside of the template to support the template. The anti-slip pad 102b is used to increase the friction force on the outside of the clamping sleeve 102a, thereby improving the limiting effect on the template.

[0036] Specifically, the fixing member 103 includes a first nut 103 a and a second nut 103 b , and the first nut 103 a and the second nut 103 b are both threadedly connected to the outer side of the screw rod 101 .

[0037] After the clamping sleeve 102a is installed, the first nut 103a and the second nut 103b are tightened to fix the clamping sleeve 102a on the outside of the template.

[0038] Specifically, the fastener 104 includes a gasket 104a and an anti-slip pattern 104b. The gasket 104a is disposed on the outer side of the screw rod 101, and the anti-slip pattern 104b is fixed on the outer side of the gasket 104a.

[0039] The gasket 104a is sleeved on the outside of the screw rod 101 and is located between the first nut 103a and the second nut 103b. Anti-slip grooves 104b are fixed on both sides of the gasket 104a, which can improve the connection strength between the first nut 103a and the second nut 103b and effectively prevent the first nut 103a and the second nut 103b from slipping.

[0040] Specifically, the threads of the first nut 103a and the second nut 103b are opposite.

[0041] The threads of the first nut 103a and the second nut 103b are opposite. After the second nut 103b is tightened, the first nut 103a is reversely fixed to the outside of the screw rod 101. The reverse threads of the two nuts are used to squeeze each other to lock the second nut 103b, thereby improving the firmness of the nut.

[0042] Example 3 Reference Figure 5 , Figure 6 , Figure 7 and Figure 8 , which is the third embodiment of the present invention, and is based on the first two embodiments.

[0043] Specifically, the fixing sleeve 201 is fixedly connected to the inside of the first nut 103a.

[0044] The interior of the fixing sleeve 201 is provided with threads.

[0045] Specifically, the adjusting member 202 includes a screw rod 202a, a fixing head 202b and a pressing block 202c. The screw rod 202a is threadedly connected to the inside of the fixing sleeve 201, the fixing head 202b is fixed to the outside of the screw rod 202a, and the pressing block 202c is fixed to the outside of the screw rod 202a.

[0046] The screw rod 202 a is threadedly connected to the interior of the fixed sleeve 201 , and the screw rod 202 a is rotated by the fixed head 202 b to drive the pressing block 202 c to move inside the fixed sleeve 201 .

[0047] Specifically, the clamping member 203 includes a connecting rod 203a, a bent rod 203b, teeth 203c and a slot 203d. The connecting rod 203a rotates inside the fixed sleeve 201, the bent rod 203b is fixed on the outside of the connecting rod 203a, the teeth 203c is fixed on the outside of the bent rod 203b, and the slot 203d is opened inside the second nut 103b.

[0048] The pressing block 202c contacts the connecting rod 203a to press it downward, and the bent rod 203b is expanded outward through the lever principle, so that the bent rod 203b is clamped inside the slot 203d on the second nut 103b. The teeth 203c on the bent rod 203b can increase the friction force on the outside of the bent rod 203b and increase the firmness of the bent rod 203b inside the slot 203d, thereby fixing the first nut 103a inside the second nut 103b to prevent the nut from falling off.

[0049] Specifically, the spring 204 is fixedly connected to the outer side of the connecting rod 203a.

[0050] When the nut needs to be removed, the screw rod 202a is rotated in the opposite direction to separate the pressure block 202c from the connecting rod 203a and lose the pressure. The spring 204 drives the two connecting rods 203a and the bent rod 203b to reset and move out from the inside of the slot 203d, thereby losing the restriction on the second nut 103b.

[0051] Specifically, the fixing rod 205 is fixedly connected inside the fixing sleeve 201 .

[0052] The fixing rod 205 is used to limit the pressing block 202c to prevent the pressing block from moving too far and losing the limit on the connecting rod 203a.

[0053] When in use, the screw rod 101 is set on the template, and then the clamping sleeve 102a is pushed to clamp with the outer side of the template to support the template, and the anti-skid pad 102b is used to increase the friction force on the outer side of the clamping sleeve 102a, thereby improving the limiting effect on the template, tighten the first nut 103a and the second nut 103b, and fix the clamping sleeve 102a to the outer side of the template. The gasket 104a is sleeved on the outer side of the screw rod 101, located between the first nut 103a and the second nut 103b, and anti-skid patterns 104b are fixed on both sides of the gasket 104a, which can improve the connection strength between the first nut 103a and the second nut 103b, and effectively prevent the first nut 103a and the second nut 103b from slipping. The threads of the first nut 103a and the second nut 103b are opposite, and the second nut 103a and the second nut 103b are opposite. After tightening 03b, the first nut 103a is reversely fixed on the outside of the screw rod 101, and the reverse threads of the two nuts are used to squeeze each other, and the second nut 103b is locked to improve the firmness of the nut, and the fixed head 202b is used to rotate the screw rod 202a to drive the pressure block 202c to move inside the fixed sleeve 201. The pressure block 202c contacts the connecting rod 203a to press it downward, and the bent rod 203b is expanded outward through the lever principle, and the bent rod 203b is clamped in the inside of the slot 203d on the second nut 103b. The teeth 203c on the bent rod 203b can increase the friction force on the outside of the bent rod 203b and improve the firmness of the bent rod 203b in the slot 203d, thereby fixing the first nut 103a to the inside of the second nut 103b to prevent the nut from falling off.
