[0010] Advantageous Effects

[0011] According to the test device of each embodiment of the present invention, compared with the traditional test device, it is provided with a support block which can contact the plane, and then drive the support plate to assist in supporting the test piece, so that the test head can be separated from manual control and automatically contact and detect the electrode material.

[0012] In addition, by setting the moving member, when the device is in use, the spring outside the round rod pushes the force-receiving plate upward, enabling the moving member to move upward and retract inside the side groove. When it is necessary to open the side view of the main body to test the electrical properties of the lithium battery electrode material, the storage member can be directly pulled outward. While the storage member moves outward, it can be opened for use, facilitating the removal of the stored components. While the storage member moves outward, the inclined grooves on the side plate can contact the two top ends of the moving member. Since the two top ends of the contact member are inclined structures, the contact member can be forced to move downward, enabling the two contact members to be automatically opened for use and supporting the bottom of the main body, making the device more stable during use. At the same time, the bottom of the main body can be separated from the ground, allowing the wind to pass through the bottom groove conveniently and facilitating the heat dissipation of the main body.

[0013] In addition, by setting the clamping rod, when the device is in use, the elastic clamping rod can be automatically stressed, thereby pushing the fixed head to move and install together, enabling the two fixed heads to be pushed by the clamping rod to be stressed, so that the fixing member can be automatically clamped on both sides of the electrode material. Then, by controlling the movement of the moving plate, the detection head can automatically contact the electrode material, enabling the clamping rod to automatically clamp and fix the electrode material, ensuring that the detection head is always stressed and in contact with the motor material for detection, avoiding continuous human control of the detection head during use, and saving manpower when using the device.

[0014] In addition, by setting the pulling member and the support block, the pulling member can drive the support block to be installed and used together. Since the support block is a wedge-shaped structure, it can increase the contact area, thereby improving the support effect of the test piece and the support plate, enabling the test piece to be stably fixed above the electrode material, and making the device completely free from manual support for testing.
