[0029] Example 1
[0030] Please refer to Figure 1 and Figure 2 As shown, this embodiment provides a multi-position quick clamping mechanism, including a base plate 10, a top pressure rod 20, and a wrench 30. The base plate 10 is provided with a locking hole. One end of the top pressure rod 20 is provided with a clamping part 201, and the other end of the top pressure rod 20 is provided with a hinge hole or hinge groove 202, and the other end of the top pressure rod 20 is provided through the locking hole. The wrench 30 is hinged to the hinge hole or hinge groove 202, and a spring 40 is provided between the wrench 30 and the base plate 10, and the spring 40 is sleeved on the top pressure rod 20. Multiple planes 301 are provided on the surfaces where the wrench 30 and the spring 40 abut against each other, and the distance between the multiple planes 301 and the hinge position of the wrench 30 is progressively increased.
[0031] Specifically, an eccentric structure is used to design multiple positions on the wrench 30. This allows for quick clamping or loosening by changing the spacing of the planes 301 by moving the wrench 30, making operation simple and efficient. The spring 40 provides stable elasticity to ensure a firm grip. The coordinated operation of all components enhances the overall mechanical performance and makes it suitable for various scenarios.
[0032] In use, place the template to be clamped between the base plate 10 and the clamping part 201 of the press rod 20, and turn the wrench 30 to the corresponding position. The press rod 20 clamps the template under the action of the spring 40, completing the fixed installation of the template. The operation is convenient and quick. By adjusting the position of the wrench 30, templates of different thicknesses can be clamped, making it highly adaptable. The spring 40 design ensures uniform clamping force, avoids template slippage or damage, and achieves the purpose of efficient template replacement.
[0033] like Figure 2 As shown, in this embodiment, the wrench 30 is provided with three planes 301, which are respectively designated as the first stop 3011, the second stop 3012, and the third stop 3013. The distance between the first stop 3011 and the hinge position of the wrench 30 shaft is minimized. Through a reasonable design of the number of stops, a stable clamping force is provided while ensuring a secure structural fit. Simultaneously, the design of multiple stops allows for multi-position adjustment, and each stop provides a stable clamping effect to meet the needs of templates of different thicknesses. Smooth switching between stops ensures convenient and efficient operation, improving work efficiency.
[0034] like Figure 2 As shown, in this embodiment, the wrench 30 is also provided with an unlocking position 3014 adjacent to the first position 3011. The distance between the unlocking position 3014 and the base plate 10 is greater than or equal to the length of the spring 40 in its natural state. The unlocking position 3014 is designed at the end, so that when switched to the unlocking position 3014, the spring 40 has no elasticity, ensuring that in the unlocked state, the pressure rod 20 fully releases the template, facilitating quick replacement.
[0035] like Figure 2 As shown, in this embodiment, the other end of the pressing rod 20 is configured as a hinge groove 202, with the opening of the hinge groove 202 inclined towards the other end. This inclined opening design prevents the hinge rod of the wrench 30 from detaching directly from the side. Simultaneously, the through-hole design at the bottom of the hinge groove 202 provides a limiting position for the hinge rod, allowing it to rotate within the groove. Combined with the pushing action of the spring 40, this ensures the wrench 30 remains stable and reliable when switching between different positions, preventing accidental detachment.
[0036] In this embodiment, multiple locking holes are provided on the substrate 10, and the number of top pressure rods 20, wrenches 30, and springs 40 is the same as the number of locking holes. This allows for the installation of a top pressure rod 20 on each locking hole, followed by the installation of wrenches 30 and springs 40 to form multiple locking points. For relatively large templates, multiple locking points can achieve multi-point clamping, enhancing clamping stability, ensuring the template does not shift during operation, and improving work efficiency. Each locking point can be independently adjusted to adapt to thickness differences in different areas, further improving the overall clamping effect and meeting the needs of complex working conditions.
[0037] like Figure 2 As shown, in this embodiment, a top pressure plate 401 is provided between the spring 40 and the wrench 30. The design of the top pressure plate 401 can form a support plane 301 on the top surface of the spring 40, which enhances the uniformity of the force on the spring 40, so as to facilitate the operation of the wrench 30 and provide stable support force to adapt to the multi-level adjustment design and improve practicality.

[0040] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
