[0037] Reference Figures 1 to 4According to the utility model, a clamp for a compression spring 610 includes a base plate 100; a bracket 200, which is arranged on the base plate 100; a pressure rod 300, which is movably connected to the bracket 200, and the lower end of the pressure rod 300 passes through the upper end surface of the bracket 200, and the center of the pressure rod 300 is provided with a through hole 310 that passes through from top to bottom; a pressure plate 400, which is movably connected to the bracket 200 and is located below the pressure rod 300; a positioning block 500, which is arranged on the base plate 100, and the positioning block 500 is used to position the lower end of the pressure rod 600.

[0038] During the production process, the pressure plate 400 is first moved toward the upper end of the bracket 200, and the lower end of the pressure rod 600 is installed in the positioning block 500 for positioning and connection, and then the lower end of the pressure plate 400 is abutted against the spring 610. After the pressure rod 300 on the bracket 200 is pressed down until it abuts against the pressure plate 400, the pressure rod 300 is continued to be driven downward to make the pressure plate 400 squeeze the spring 610. After the spring 610 is compressed, a tool is inserted into the through hole in the center of the pressure rod 300 to tighten the bolts above the pressure rod 600, so that the spring 610 is fixed to the rod body of the pressure rod 600, completing the entire assembly process.

[0039] The application of the above-mentioned clamp for compressing the spring 610 has at least the following beneficial effects: during the production process, the lower end of the pressure rod 600 is fixedly connected to the positioning block 500, and the spring 610 is loaded into the pressure rod 600 from the upper end and pressed on the upper end of the spring 610 by the pressure plate 400, and then the pressure rod 300 on the driving bracket 200 is pressed down and abuts against the pressure plate 400. The downward force of the pressure rod 300 causes the pressure plate 400 to move downward, and at the same time, the spring 610 is compressed downward. After being compressed to the corresponding position, the screw above the pressure rod 600 is tightened from the through hole 310 in the center of the pressure rod 300, thereby restricting the spring 610 to the pressure rod 600. Compared with compressing the spring 610 by hand, compressing the spring 610 by the pressure rod 300 and the pressure plate 400 is more labor-saving and more convenient to operate.

[0040] According to some embodiments of the utility model, a threaded hole is provided at the upper end of the bracket 200, and a thread is provided on the rod body of the pressure rod 300. The bracket 200 and the pressure rod 300 are connected by threads. In the process of driving the pressure rod 300 to rotate and press down, there is no need to add other additional structures to fix the pressure rod 300, so that the pressure rod 300 can remain stationary during the process of stopping rotation, thereby ensuring that the spring 610 can always be in a compressed state and will not recover.

[0041] According to some embodiments of the utility model, a handle 320 is provided at the upper end of the pressure rod 300, and the handle 320 is used to drive the pressure rod 300 to rotate on the bracket 200. The pressure rod 300 is rotated by the handle 320, which is convenient to operate and very labor-saving.

[0042] According to some embodiments of the present invention, a limiting structure 330 is provided at the upper end of the pressure rod 300 , and the limiting structure 330 is used to limit the maximum distance that the pressure rod 300 can move downward.

[0043] According to some embodiments of the utility model, a positioning groove 510 is provided on the side of the positioning block 500, and a positioning hole 520 is provided in the positioning groove 510. The positioning groove 510 is used to accommodate the lower end of the pressure rod 600. The lower end of the pressure rod 600 is fixedly connected to the positioning hole 520 through a connecting member. The connecting member is set as a bolt or a positioning pin. In this embodiment, the shape of the positioning groove 510 matches the shape of the pressure rod 600.

[0044] According to some embodiments of the utility model, an opening groove 410 is provided on the pressure plate 400, and the opening groove 410 is used to avoid the pressure rod 600. The opening direction of the opening groove 410 is opposite to the opening direction of the positioning groove 510. The opening groove 410 is used to allow the rod body of the pressure plate 600 to pass through, and at the same time, it can support the side of the rod body. At the same time, the opening direction of the opening groove 410 is opposite to the positioning groove 510, so it can play a complementary supporting role on both sides of the pressure rod 600 to prevent the pressure rod 600 from tilting.

[0045] According to some embodiments of the present invention, a sliding groove is provided on the side wall of the bracket 200, and a sliding block is provided on the side of the pressing plate 400, and the sliding block is slidably disposed in the sliding groove.

[0046] It should be noted that in this specification, terms such as "one embodiment", "some embodiments", "basic embodiment", "extended embodiment" etc. may be used to describe several embodiments of the utility model. The specific features, structures, materials or characteristics in the several embodiments may be combined in accordance with the principles and purposes of the utility model.

[0047] Although some embodiments of the utility model have been shown and described in this specification, the utility model should not be limited to the above-mentioned embodiments. As long as the technical effects of the utility model are achieved by the same or equivalent means, any changes, modifications, equivalent substitutions and equivalent variations of these embodiments within the spirit and principles of the present disclosure and without departing from the principles and purpose of the present utility model should be included in the scope of protection of the present disclosure and should be deemed to belong to the scope of protection of the utility model.
