The lower end of the guide post has a square post for engaging with the square hole, and the guide post slides in conjunction with the round hole. The end cap has a threaded hole, and the outer wall of the guide post has external threads. This utility model can fix the monitoring probe and the injection probe in practical use, ensuring their positional stability and guaranteeing the conduction of experiments.

[0004] This patent can clamp and fix the injection probe and the monitoring probe, but existing devices cannot be quickly disassembled and assembled, so their practicality needs to be improved. Utility Model Content

[0005] The purpose of this invention is to solve the problem that existing devices cannot be quickly disassembled and assembled, and their practicality needs to be improved.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a cable bundle injection conduction sensitivity probe clamp, comprising a base, wherein convenient disassembly and assembly components are connected to both bottom surfaces of the base, the convenient disassembly and assembly components comprising a fixing frame, wherein a monitoring probe and an injection probe are respectively connected inside the two sets of fixing frames, and slots are provided on the front and rear end surfaces of the monitoring probe and the injection probe, wherein connecting blocks are connected to the front and rear end surfaces of the fixing frame, wherein two sets of springs are connected inside the connecting blocks, wherein push rods are inserted into the two sets of springs, wherein handles are connected to the rear ends of the two sets of push rods, and push plates are connected to the front ends of the two sets of push rods, wherein insert blocks are connected to the surface of the push plates.

[0007] Furthermore, the surface of the insert block is provided with a bevel, and the insert block and the slot form an interlocking connection.

[0008] Furthermore, the push plate and the spring form an elastic structure, and the outer surface of the push plate is in contact with the inner wall of the connecting block.

[0009] Furthermore, the position and size of the monitoring probe and the injection probe are matched with the position and size of the two sets of fixtures.

[0010] Furthermore, the bottom of the base is provided with a lifting adjustment component, which includes a base plate, and a support frame is connected to the center of the surface of the base plate.

[0011] Furthermore, a worm gear is inserted into the surface of the base plate, a worm wheel is connected to the surface of the worm gear, and a one-way screw is rotatably connected inside the support frame.

[0012] Furthermore, each of the four corners of the base is connected to a sliding rod, each of the four corners of the base plate is connected to a sliding sleeve, and a lifting frame is connected to the center of the base.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] 1. In this utility model, when it is necessary to install the monitoring probe and the injection probe, they can be inserted into the fixing frame and fixed by the automatic insertion of the plug into the slot. When it is necessary to disassemble, simply pull the handles on both sides to pull the plug out of the slot, and then pull the monitoring probe upward to complete the disassembly.

[0021] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0023] Example 1, as Figure 1 - Figure 3 As shown, this utility model provides a cable bundle injection conduction sensitivity probe clamp, including a base 1. Both sides of the base 1 are connected to easy-to-disassemble components 2. Each easy-to-disassemble component 2 includes a fixing frame 201. A monitoring probe 202 and an injection probe 203 are respectively connected inside the two fixing frames 201. Slots 204 are provided on the front and rear ends of both the monitoring probe 202 and the injection probe 203. Connecting blocks 205 are connected to the front and rear ends of the fixing frames 201. Two sets of springs 206 are connected inside the connecting blocks 205. Push rods 207 are inserted into each of the two sets of push rods 207. Handles 208 are connected to the rear ends of the two sets of push rods 207. Push plates 209 are connected to the front ends of the two sets of push rods 207. Insert blocks 210 are connected to the surface of the push plates 209. The surface of the insert blocks 210 has bevels. The insert blocks 210 and slots 204 form an interlocking connection. The push plates 209 and springs 206 form an elastic structure. The outer surface of the push plates 209 is in contact with the inner wall of the connecting block 205. The position and size of the monitoring probe 202 and the injection probe 203 match the position and size of the two sets of fixing brackets 201.

[0024] The effect achieved by Embodiment 1 is that when installing the monitoring probe 202 and the injection probe 203, they can be directly pushed into the fixing frame 201. When the angled opening of the insertion block 210 is squeezed, it will automatically retract. When the monitoring probe 202 or the injection probe 203 is pushed into the fixing frame 201, the spring 206 will push the push plate 209 through its own elasticity, thereby driving the insertion block 210 into the slot 204, thus completing the quick installation of the monitoring probe 202 and the injection probe 203. When it is necessary to disassemble them, the handles 208 can be pulled to both sides at the same time, so that the handles 208 can drive the push plate 209 through the push rod 207 to squeeze the spring 206 and drive the insertion block 210 out of the slot 204. Then, the bottom of the monitoring probe 202 can be pushed upward with a finger to complete the disassembly. This avoids the problem that the existing device cannot quickly disassemble and install the monitoring probe 202 and the injection probe 203, and improves the overall practicality.

[0025] Example 2, as Figure 1 and Figure 4 As shown, a lifting adjustment assembly 3 is provided at the bottom of the base 1. The lifting adjustment assembly 3 includes a base plate 301. A support frame 302 is connected to the center of the surface of the base plate 301. A worm gear 303 is inserted into the surface of the base plate 301. A worm wheel 305 is connected to the surface of the worm gear 303. A one-way screw 306 is rotatably connected inside the support frame 302. Slide rods 307 are connected to the four corners of the bottom of the base 1. Sliding sleeves 308 are connected to the four corners of the surface of the base plate 301. A lifting frame 309 is connected to the center of the base of the base 1.

[0026] The effect achieved in Embodiment 2 is that when the height of the fixed frame 201 needs to be adjusted, it can be operated according to the actual testing requirements: if it is necessary to raise the monitoring probe 202 and the injection probe 203, the handle 304 is rotated counterclockwise to drive the worm 303 to rotate in the opposite direction. The worm 303 and the worm wheel 305 mesh and drive the one-way screw 306 to rotate in the opposite direction synchronously. At this time, the one-way screw 306 and the threaded pair of the lifting frame 309 generate relative movement, driving the lifting frame 309 to rise smoothly along the guide structure of the slide bar 307 and the slide sleeve 308, and then drive the probe assembly to be raised synchronously to the target height through the base 1 and then stop rotating; if it is necessary to lower the probe height, the handle 304 is rotated clockwise, and the worm wheel 305 and the worm 303 rotate forward to drive the one-way screw 306 to drive the lifting frame 309 to descend. The entire adjustment process is stable through the self-locking characteristics of the worm wheel and the worm and the guide mechanism of the slide bar, effectively solving the problems of cumbersome height adjustment operation and low positioning accuracy of traditional devices.

[0027] Working principle: When it is necessary to install the monitoring probe 202 and the injection probe 203, they can be inserted into the fixing bracket 201 and fixed by the insertion block 210 automatically inserting into the slot 204. When it is necessary to disassemble, simply pull the handles 208 to both sides to pull the insertion block 210 out of the slot 204, and then pull the monitoring probe 202 upward to complete the disassembly. This avoids the problem of existing devices being unable to quickly disassemble and assemble the monitoring probe 202 and the injection probe 203, improving the overall practicality. When it is necessary to adjust the height, the worm gear 303 can be rotated to mesh with the worm wheel 305. Through the meshing connection, the one-way screw 306 is rotated, and then the base 1 is adjusted in height through the threaded rotation connection. This achieves the adjustment of the monitoring probe 202 and the injection probe 203, avoiding the inconvenience of height adjustment in traditional devices.

[0028] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
