[0010] As a further improvement of this utility model: a handwheel is provided at one end of the first adjusting screw located outside the rectangular limiting frame and at the top of the second adjusting screw.
[0011] The beneficial effects of this utility model are as follows: The spacing between the support plates is adjusted by the first adjusting screw to accommodate devices of different lengths; the second adjusting screw drives the clamping block to move down, so that the arc-shaped clamping groove firmly holds the electrode, and the spring of the elastic component can buffer the clamping force to avoid damage to the workpiece, thereby improving the adaptability and operating efficiency of all-metal ceramic packages of different specifications.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0018] Example 1, referring to Figure 1-4A fixture for all-metal ceramic encapsulation includes a base plate 1. A rectangular limiting frame 2 is fixed to the upper surface of the base plate 1. First adjusting screws 3 are screwed to both ends of the rectangular limiting frame 2. Support plates 4 are rotatably mounted on one end of each of the two first adjusting screws 3 inside the rectangular limiting frame 2 via bearings. The two support plates 4 are slidably engaged with the inner wall of the rectangular limiting frame 2. Electrode placement grooves 5 are opened in the middle of the top of each of the two support plates 4. Lifting frames are fixed to the top of each of the two support plates 4. Clamping blocks 11 are connected to each of the two lifting frames via elastic components. The two clamping blocks 11 are engaged with the two electrode placement grooves 5 respectively. Arc-shaped clamping grooves 6 are opened at the lower end of each of the two clamping blocks 11.
[0019] The lifting frame includes a U-shaped rod 9 fixed to the top of the support plate 4. A second adjusting screw 8 is screwed to the middle of the horizontal section of the U-shaped rod 9. A vertical rod 12 is rotatably installed at the lower end of the second adjusting screw 8 through a bearing. A fixing plate 7 is fixed between the two vertical sections of the U-shaped rod 9. The vertical rod 12 is movably inserted into the middle of the fixing plate 7.
[0020] A handwheel is provided at one end of the first adjusting screw 3 located outside the rectangular limiting frame 2 and at the top of the second adjusting screw 8.
[0021] According to the length of the device, turn the two first adjusting screws 3 to adjust the distance between the two support plates 4. Place the two electrodes at both ends of the device into the two electrode placement slots 5 respectively. By turning the two second adjusting screws 8 respectively, the two uprights 12 will drive the two clamping blocks 11 to move down. The arc-shaped clamping slots 6 at the bottom of the two clamping blocks 11 will clamp the two electrodes at both ends of the device respectively, thereby fixing the device.
[0022] Example 2 is an optimization based on Example 1, specifically: The elastic component includes two T-shaped pins 10 symmetrically fixed to the upper end of the clamping block 11, a circular plate 13 connected to the lower end of the upright 12, the two T-shaped pins 10 being movably inserted into the circular plate 13, and a spring 14 being sleeved on the part of the two T-shaped pins 10 located between the circular plate 13 and the clamping block 11.
[0023] The two T-pins 10 are the same size and are symmetrically distributed on the circular plate 13.
[0024] When the upright 12 moves downward, the arc-shaped clamping groove 6 at the bottom makes contact. Then, the second adjusting screw 8 is turned to make the upright 12 move downward. The circular plate 13 and the T-pin 10 slide relative to each other, thereby compressing the spring 14 and avoiding damage to the all-metal ceramic due to excessive clamping force to a large extent.
[0025] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
