[0027] In the description of the present utility model, "a plurality" means more than two. If there is a description of "first" or "second", it is only for the purpose of distinguishing the technical features, and cannot be understood as indicating or implying the relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0028] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0029] Reference Figure 1 and Figure 2 As shown, a field effect tube fixing fixture includes: a tray 100 and a limiting mechanism 200. The tray 100 is provided with at least one groove 110, and the field effect tube is placed in the groove 110. The limiting mechanism 200 can be removably covered on the tray 100. The limiting mechanism 200 is provided with a limiting rod 210 that corresponds to the groove 110 one by one and can slide up and down to limit the field effect tube during grinding.

[0030] In the embodiment of the utility model, the field effect tube is accommodated by the groove 110 on the tray 100. When the position is required to be limited, the limiting mechanism 200 is covered on the tray 100, and then the limiting rod 210 is slid to abut against the field effect tube, so as to fix the field effect tube in the groove 110. Since the limiting rod 210 can slide up and down, field effect tubes of different sizes can be fixed, and there is no need to configure multiple fixing fixtures of different sizes, thereby reducing the production cost.

[0031] It should be noted that the size of the above-mentioned groove 110 is adapted to the size of the field effect tube of the largest size to be processed, that is, the field effect tube of the largest size can be placed in the groove 110. Figure 1 As shown, when the field effect tube is placed before the groove 110, the limiting rod 210 is located at the top of the groove 110 to provide the largest possible field effect tube placement range; when the field effect tube is placed in the groove 110, the bottom of the field effect tube base abuts against the inner bottom of the groove. Figure 2 As shown, the limiting rod 210 then slides downward and abuts against the top of the field effect tube base, so that the field effect tube is fixed in the groove 110, which is convenient for subsequent grinding processing.

[0032] refer to Figure 3 As shown, in this embodiment, there are multiple grooves 110 and they are arranged in sequence from top to bottom, so that multiple field effect tubes can be fixed and processed at the same time, thereby improving processing efficiency. It should be understood that when there are multiple grooves 110, the number of limit rods 210 is also multiple and corresponds one-to-one to the grooves 110.

[0033] In this embodiment, the groove 110 extends from one side of the tray 100 to the other side, which can increase the width of each groove 110 so that each groove 110 can accommodate multiple field effect transistors, further increasing the number of field effect transistors that can be fixed at the same time, and further improving processing efficiency.

[0034] In this embodiment, the limiting mechanism 200 includes a bracket 220, a limiting rod 210 and a guide rail 230. The bracket 220 is rotatably connected to the tray 100. The guide rail 230 is set on the bracket 220 on one side of the tray 100. The limiting rod 210 is slidably connected to the guide rail 230 through a slider 240.

[0035] In this embodiment, the bracket 220 includes a horizontal plate and two vertical plates, and the two vertical plates are respectively fixed at the two ends of the horizontal plate to form a square frame structure with three sides. The middle area of ​​the bracket 220 matches the shape of the tray 100, that is, when the limiting mechanism 200 covers the tray 100, the tray 100 is just embedded in the middle area of ​​the bracket 220, which can improve the stability of the overall structure. The guide rail 230 is installed on the vertical plate, and the limiting rod 210 is slidably connected to the guide rail 230 through the slider 240. The limiting rod 210 can slide up and down through the slider 240, so as to approach / leave the field effect tube.

[0036] In this embodiment, there are two guide rails 230, which are respectively arranged on the brackets 220 on both sides of the tray 100. The two guide rails 230 respectively support the two ends of the limit rod 210, which can further increase the stability of the overall structure. In addition to two, three or more guide rails 230 can also be set to support the limit rod 210.

[0037] In this embodiment, one end of the limiting mechanism 200 is rotatably connected to one end of the tray 100. The above-mentioned one end of the limiting mechanism 200 is rotatably connected to one end of the tray 100, which means that the horizontal plate of the guide rail 230 is rotatably connected to the top of the tray 100. In this embodiment, the horizontal plate is connected to the tray 100 through a hinge to achieve rotation. In addition to the hinge, a rotating shaft or other rotatable connection structure can also be used.

[0038] In this embodiment, a handle 250 is provided on the other end of the limiting mechanism 200. Specifically, in this embodiment, the handle 250 is installed on the other end of the bracket 220 corresponding to the horizontal plate. Figure 4 As shown, after the processing is completed, the staff can lift the handle to lift the entire limiting mechanism 200 to facilitate material unloading.

[0039] The utility model also relates to a field effect tube processing device, comprising the above-mentioned field effect tube fixing fixture.

[0040] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
