[0049] Furthermore:

[0050] In an optional embodiment, a U-shaped positioning pin 35 is slidably connected to the surface of the positioning block 31, and a plurality of positioning holes 34 matching the U-shaped positioning pin 35 are opened on the surface of the card plate 32. A gasket ring 37 is fixedly connected to the surface of the U-shaped positioning pin 35, and a first spring 38 is wound around the surface of the U-shaped positioning pin 35. The two ends of the first spring 38 are fixedly connected to the gasket ring 37 and the positioning block 31, respectively.

[0051] In this embodiment: Because the U-shaped positioning pin 35 is slidably connected to the surface of the positioning block 31, and several positioning holes 34 matching the U-shaped positioning pin 35 are formed on the surface of the clamping plate 32, this design allows the operator to insert the U-shaped positioning pin 35 into the corresponding positioning hole 34, thereby adjusting the position of the clamping plate 32 and determining the position of the detection probe 28. Because a first spring 38 is provided, the spring force keeps the U-shaped positioning pin 35 inclined to be inserted into the positioning hole 34, ensuring the stability of the clamping plate 32's position and preventing changes in the positions of the clamping plate 32 and the detection probe 28 during the detection process.

[0052] Furthermore:

[0060] In the embodiment, the second spring 311 is provided to automatically reset the U-shaped lock handle 39 to the initial position, which is convenient for next operation and also helps to maintain the compactness and stability of the structure of the device.

[0061] Further,

[0062] In an optional embodiment, the surface of the mounting seat 33 is provided with an adjusting bolt 314 for fine adjustment of the position of the detection probe 28.

[0063] In the embodiment, the adjusting bolt 314 is provided to adjust the position of the detection probe 28 in the mounting groove 315 after the position of the clamping plate 32 is adjusted by the U-shaped positioning pin 35, so that the detection is more accurate.

[0064] Further,

[0065] In an optional embodiment, the threaded rod 42 is fixedly connected with a knob 43 on the side away from the rubber plate 44.

[0066] In the embodiment, the knob 43 is provided to facilitate the operator to firmly press the pressure container.

[0067] Working principle: because the setting has the mobile assembly 2, the adjustment assembly 3 and the fixed assembly 4, the fixed frame 21 in mobile assembly 2 plays the role of supporting and installing screw rod 22 and guide rod 23, screw rod 22 and guide rod 23 are parallelly arranged inside fixed frame 21, screw rod 22 is used to provide power drive detection ring 24 to move, guide rod 23 provides guide for the movement of detection ring 24, ensures its linear motion.Detection ring 24 is threadedly connected with screw rod 22, so that when screw rod 22 rotates, detection ring 24 can move along the axial direction of screw rod 22, at the same time, detection ring 24 is slidingly connected with guide rod 23, further ensures the stability of movement.Detection ring 24 is provided with detection probe 28 on the surface, detection probe 28 moves with detection ring 24, this design is used to realize the detection of different positions of container body 11, because the slide groove 36 is opened on the positioning block 31, the clamping plate 32 is used to slide in its inside, so as to adjust the position of clamping plate 32.The mounting seat 33 fixed on the surface of clamping plate 32 is provided with mounting groove 315 for placing detection probe 28.Through this design, the position adjustment of detection probe 28 in a certain range can be realized to adapt to different detection requirements, because two vertical plates 41 are symmetrically arranged on the surface of base plate 1, threaded rod 42 is threadedly connected on vertical plate 41, rotating threaded rod 42 can make it move axially on vertical plate 41.Rubber plate 44 on the adjacent end of threaded rod 42 is used to contact and fix container body 11, rubber plate 44 can increase the friction force with container body 11, at the same time, it can avoid damaging the surface of container, ensures that container body 11 remains stable during detection, because output gear 25 and gear ring 26 are engaged, when output gear 25 rotates, it makes support plate 27 rotate through gear ring 26, because support plate 27 is fixedly connected with positioning block 31, positioning block 31 moves with it, positioning block 31 drives detection probe 28 to move, this design further improves the detection range, because the first motor 210 and the second motor 29 are arranged, this design further facilitates detection probe 28 to detect container body 11 from different angles, because U-shaped positioning pin 35 is slidingly connected on the surface of positioning block 31, a plurality of positioning holes 34 matched with U-shaped positioning pin 35 are opened on the surface of clamping plate 32, this design enables workers to insert U-shaped positioning pin 35 into corresponding positioning hole 34, so as to adjust the position of clamping plate 32, thereby determining the position of detection probe 28.Because of the first spring 38, the U-shaped positioning pin 35 has the tendency to be inserted into the positioning hole 34 by the elastic force provided by the first spring 38, which ensures the stability of the position of the card plate 32 and prevents the position of the card plate 32 and the detection probe 28 from changing during detection. When the U-shaped lock handle 39 is pulled upward, the inclined plate 310 moves upward with the U-shaped lock handle 39, and the slope of the inclined plate 310 interacts with the inclined groove 313 of the U-shaped positioning pin 35, so that the U-shaped positioning pin 35 is pulled out of the positioning hole 34, thereby adjusting the position of the card plate 32 and the detection probe 28. When the U-shaped lock handle 39 is loosened, the U-shaped positioning pin 35 is inserted into the positioning hole 34 again under the action of the first spring 38, and the position of the card plate 32 is fixed. Because the slope is arranged on the side of the inclined plate 310 facing the U-shaped positioning pin 35, the slope is designed to enable the U-shaped positioning pin 35 to be positioned by passing through the positioning hole 34 without the need for manual lifting of the U-shaped lock handle 39 again, which is engaged with the inclined plate 310, thereby facilitating the adjustment of the position of the detection probe 28 by the operator and optimizing the convenience of operation. Because of the second spring 311, the U-shaped lock handle 39 is automatically reset to the initial position, which is convenient for next operation and also helps to maintain the compactness and stability of the structure of the device. Because of the adjusting bolt 314, the position of the detection probe 28 in the mounting groove 315 can be adjusted after the position of the card plate 32 is adjusted by the U-shaped positioning pin 35, so that the detection is more accurate. Because of the knob 43, the design facilitates the operator to stabilize the pressure container.
