[0024] The embodiments of this utility model are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the embodiments of this utility model, and should not be construed as limiting the utility model.

[0025] In the description of the embodiments of this utility model, it should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. They are only for the convenience of describing the embodiments of this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0026] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of embodiments of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0027] In this embodiment of the invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this embodiment of the invention according to the specific circumstances.

[0028] In one embodiment of this utility model, such as Figures 1-3 As shown, a test fixture is provided, including a base 1, a frame 2, a first fixture assembly 3, and a second fixture assembly 4. The frame 2 is fixedly connected to the base 1, and both the first fixture assembly and the second fixture assembly 4 are connected to the frame 2. The first fixture assembly is disposed on one side of the second fixture assembly 4. A slide rail 21 is fixedly connected to the frame 2, and a first slider 22 and a second slider 23 are slidably connected to the slide rail 21.

[0029] The first clamping assembly 3 includes a first fixed frame 31, a first swing arm 32, a first lifting rod 33, a first handle 34, a first lifting frame 35, and a first clamping plate 36. The first fixed frame 31 is fixedly connected to the machine frame 2. The first swing arm 32 is rotatably connected to the first fixed frame 31. The first lifting rod 33 is fixedly connected to the first swing arm 32. The first handle 34 is rotatably connected to the first swing arm 32. The first lifting frame 35 is fixedly connected to the first lifting rod 33 and the first slider 22, respectively. The first clamping plate 36 is fixedly connected to the first lifting frame 35. The first swing arm 32 is rotatably connected to the first fixed frame 31. When the first handle 34 is rotated, the first swing arm 32 can rotate around the connection point with the first fixed frame 31, changing its angular position, thereby driving the first lifting rod 33 and other components fixedly connected to it to move synchronously, changing the spatial posture of the entire first clamping assembly 3, and preparing for subsequent operations such as clamping the workpiece. The first handle 34 is rotatably connected to the first swing arm 32. The operator can apply a torque to the first swing arm 32 by operating the first handle 34, so that the first swing arm 32 can rotate in the desired direction. The rotation of the first swing arm 32 drives the first lifting rod 33 to move. Since the first lifting frame 35 is fixedly connected to the first lifting rod 33 and the first slider 22 respectively, the movement of the first lifting rod 33 can further drive the first lifting frame 35 to move up and down along the first slider 22 on the first slide rail 21, and finally drive the first clamping plate 36 fixed on the first lifting frame 35 to move up and down to move closer to or away from the workpiece to achieve clamping or releasing action.

[0030] The second clamping assembly 4 includes a second fixed frame 41, a second swing arm 42, a second lifting rod 43, a second handle 44, a second lifting frame 45, and a second pressure plate 46. The second fixed frame 41 is fixedly connected to the frame 2. The second swing arm 42 is rotatably connected to the second fixed frame 41. The second lifting rod 43 is fixedly connected to the second swing arm 42. The second handle 44 is rotatably connected to the second swing arm 42. The second lifting frame 45 is fixedly connected to the second lifting rod 43 and the second slider 23. The second pressure plate 46 is fixedly connected to the second lifting frame 45 and is positioned above the first pressure plate 36. The second clamping assembly 4 operates on the same principle as the first clamping assembly 3.

[0031] In another embodiment of the present invention, a first guide cylinder 37 is fixedly connected to the first fixed frame 31, and a first lifting rod 33 is movably inserted through the first guide cylinder 37, with the first guide cylinder 37 having a guiding function for the first lifting rod 33.

[0032] In another embodiment of this utility model, a rubber plate 38 is fixedly connected to the bottom side of the first pressing plate 36. Multiple rubber plates 38 are provided and evenly distributed on the first pressing plate 36. The rubber plates 38 have an anti-slip function, enabling more stable fixation of the battery.

[0033] In another embodiment of this utility model, a positioning post 11 is fixedly connected to the base 1, and positioning holes are provided on the first lifting frame 35 and the first pressing plate 36. The positioning post 11 is arranged to coincide with the positioning hole. After the first pressing plate 36 moves down, the positioning post 11 is inserted into the positioning hole for further positioning.

[0034] In another embodiment of this utility model, a second guide cylinder 47 is fixedly connected to the second fixed frame 41, and a second lifting rod 43 is movably inserted through the second guide cylinder 47. The second guide cylinder 47 has a guiding function for the second lifting rod 43.

[0035] In another embodiment of this utility model, two slide rails 21 are provided and arranged in parallel. Both slide rails 21 are fixedly connected to the frame 2, and each slide rail 21 is provided with a first slider 22 and a second slider 23. By providing two slide rails 21, stability is improved.

[0036] The test fixture provided in this application has a first clamping assembly 3 that moves down along the slide rail 21 and a first clamping plate 36 that clamps the battery once. The second clamping assembly 4 moves down along the slide rail 21 and a second clamping plate 46 that clamps the first clamping plate 36, thereby clamping the battery a second time, resulting in a more ideal battery test effect.

[0037] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
