[0039] The clamping sleeve 102a is symmetrically sleeved on the outer side of the screw rod 101. The screw rod 101 is arranged on the template, and then the clamping sleeve 102a is pushed to be clamped with the outer side of the template to support the template. The anti-slip pad 102b is used to increase the friction on the outer side of the clamping sleeve 102a, thereby improving the limit effect on the template.

[0040] Specifically, the fixing member 103 includes a first nut 103a and a second nut 103b, and both the first nut 103a and the second nut 103b are threadedly connected to the outer side of the screw rod 101.

[0041] 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 outer side of the template.

[0042] Specifically, the fastening member 104 includes a gasket 104a and an anti-slip pattern 104b. The gasket 104a is arranged 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.

[0043] The gasket 104a is sleeved outside the screw rod 101 and is located between the first nut 103a and the second nut 103b. Anti-slip threads 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 slippage between the first nut 103a and the second nut 103b.

[0044] Specifically, the threads of the first nut 103a and the second nut 103b are opposite.

[0045] 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 outside the screw rod 101. By using the reverse threads of the two nuts, they are mutually extruded to lock the second nut 103b and improve the firmness of the nut.

[0046] Embodiment 3

[0047] Refer to Figure 5 、 Figure 6 、 Figure 7 and Figure 8 This is the third embodiment of the present utility model, which is based on the first two embodiments.

[0048] Specifically, the fixing sleeve 201 is fixedly connected inside the first nut 103a.

[0049] Threads are provided inside the fixing sleeve 201.

[0050] Specifically, the adjusting member 202 includes a lead screw 202a, a fixed head 202b, and a pressing block 202c. The lead screw 202a is threadedly connected inside the fixing sleeve 201. The fixed head 202b is fixed outside the lead screw 202a, and the pressing block 202c is fixed outside the lead screw 202a.

[0051] The lead screw 202a is threadedly connected inside the fixing sleeve 201. By rotating the lead screw 202a with the fixed head 202b, the pressing block 202c is driven to move inside the fixing sleeve 201.

[0052] Specifically, the clamping member 203 includes a connecting rod 203a, a bent rod 203b, teeth 203c, and a card slot 203d. The connecting rod 203a rotates inside the fixing sleeve 201. The bent rod 203b is fixed outside the connecting rod 203a. The teeth 203c are fixed outside the bent rod 203b. The card slot 203d is opened inside the second nut 103b.

[0053] The briquette 202c contacts the connecting rod 203a and presses it downward. Through the lever principle, the bent rod 203b expands outward, and the bent rod 203b is clamped inside the slot 203d of the second nut 103b. The teeth 203c on the bent rod 203b can increase the friction on the outer side of the bent rod 203b and improve the firmness of the bent rod 203b inside the slot 203d, thereby fixing the first nut 103a inside the second nut 103b and preventing the nut from falling off.

[0054] Specifically, the spring 204 is fixedly connected to the outer side of the connecting rod 203a.

[0055] When it is necessary to remove the nut, rotate the screw rod 202a in the reverse direction to separate the briquette 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 of the slot 203d, losing the restriction on the second nut 103b.

[0056] Specifically, the fixing rod 205 is fixedly connected inside the fixing sleeve 201.

[0057] The fixing rod 205 is used to limit the position of the briquette 202c to prevent the briquette from moving too far and losing the limit on the connecting rod 203a.

[0058] During use, the screw rod 101 is arranged on the template, and then the clamping sleeve 102a is pushed to be clamped with the outer side of the template to support the template. The anti-slip pad 102b is used to increase the friction 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 to fix the clamping sleeve 102a on the outer side of the template. The gasket 104a is sleeved on the outer side of the screw rod 101 and is located between the first nut 103a and the second nut 103b. Anti-slip lines 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 slippage between the first nut 103a and the second nut 103b. 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 on the outer side of the screw rod 101. Using the reverse threads of the two nuts, they are pressed against each other to lock the second nut 103b and improve the firmness of the nut. The fixing head 202b is used to rotate the screw rod 202a to drive the briquette 202c to move inside the fixing sleeve 201. The briquette 202c contacts the connecting rod 203a and presses it downward. Through the lever principle, the bent rod 203b expands outward, and the bent rod 203b is clamped inside the slot 203d of the second nut 103b. The teeth 203c on the bent rod 203b can increase the friction on the outer side of the bent rod 203b and improve the firmness of the bent rod 203b inside the slot 203d, thereby fixing the first nut 103a inside the second nut 103b and preventing the nut from falling off.
