[0019] In order to make the purpose, technical solutions and advantages of the embodiments of the utility model clearer, the technical solutions in the embodiments of the utility model will be clearly and completely described below. Obviously, the described embodiments are partial embodiments of the utility model, rather than all embodiments.

[0020] In the description of the present utility model, it should be understood that the terms "center", "lateral", "longitudinal", "front", "rear", "left", "right", "up", "down", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the scope of protection of the present utility model. When a component is referred to as being "fixed to" another component, it may be directly on the other component or there may also be a centered component. When a component is considered to be "connected" to another component, it may be directly connected to the other component or there may be a centered component at the same time. When a component is considered to be "set on" another component, it may be directly set on the other component or there may be a centered component at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0021] like Figures 1 to 4 As shown, the test fixture quick replacement device of the utility model comprises:

[0022] Base 1: A plug installed on the base 1; the plug can be connected to electricity or gas, etc.

[0023] The card plate 2 is slidably mounted on the base 1 , and a slide groove 21 is provided on the card plate 2 , and the slide groove 21 is divided into a clamping section, a pressing section and a fixing section 213 ; a connecting block 3 sliding in the slide groove 21 is provided on the fixture; the width of the clamping section and the fixing section 213 is wider than that of the connecting block 3 .

[0024] The connecting block 3 is generally a column, which can be fixedly installed on the jig or rolled on the jig. It is conventional to choose to fix it on the jig, which has low cost and low processing difficulty; the engaging section is used for initial contact with the connecting block 3. Taking into account the error, the engaging section is wider than the connecting block 3, so that the connecting block 3 can enter the engaging section more conveniently; the pressing section is used to press the jig down and close to the base 1. The pressing section is arc-shaped. During the pressing process, the connecting block 3 contacts the side wall of the slide groove 21, so that the jig is close to the base 1; the width of the fixed section 213 is slightly wider than the connecting block 3, generally selected to be 0.5 to 1 cm, that is, the clearance between the connecting block 3 and the slide groove 21 is matched, the design error is convenient for the connection of the plug, and the guidance is achieved through the slide groove 21. The structure is simple and reliable.

[0025] The card plate 2 is connected with a driving device for driving the card plate 2 to rise and fall, and the driving device includes a gear 4 and a rack 5 meshing with the gear 4, and the rack 5 is fixedly connected to the card plate 2. The gear 4 is fixedly mounted on the rotating shaft, and one end of the rotating shaft is fixedly connected to a hand lever. When the card plate 2 needs to be controlled to rise and fall, the hand lever is rotated to rotate the rotating shaft, which can drive the two gears 4 to rotate, thereby driving the two racks 5 to move up and down, so as to achieve the purpose of driving the card plate 2 to rise and fall.

[0026] The clamping plate 2 is fixedly connected with a guide block 6, and the guide block 6 is provided with an inclined surface. The guide block 6 plays a central role. During the movement of the jig, under the action of the inclined surfaces of the guide blocks 6 on both sides, the jig moves to the middle, which is convenient for the joint insertion.

[0027] The base 1 is fixedly connected with a plug-in positioning rod 7, which can be inserted into the fixture to fix the fixture.

[0028] Working principle:

[0029] Turning the hand lever causes the shaft to rotate, which can drive the two gears 4 to rotate, thereby driving the two racks 5 to move up and down. Under the action of the inclined surfaces of the guide blocks 6 on both sides, the fixture moves toward the middle, and the positioning rod can be inserted into the fixture. The connecting block 3 can more conveniently enter the engaging section. During the downward pressing process, the connecting block 3 contacts the side wall of the slide groove 21, so that the fixture is close to the base 1. At the same time, the plugs are connected to each other.

[0030] Finally, it should be noted that the plug referred to in this application is a synonym. The fixture is provided with a female plug, and the seat is provided with a male plug.

[0031] The standard parts used in the utility model can be purchased from the market, and special-shaped parts can be customized according to the description in the specification and the drawings. The specific connection methods of each part adopt the conventional means such as mature bolts, rivets, welding, etc. in the prior art. The machinery, parts and equipment all adopt the conventional models in the prior art, and the circuit connection adopts the conventional connection method in the prior art, which will not be described in detail here. The content not described in detail in this specification belongs to the prior art known to professional and technical personnel in this field.

[0032] It should be understood that those skilled in the art can make improvements or changes based on the above description, and all these improvements and changes should fall within the scope of protection of the claims attached to the utility model.
