Similar products include moisture meter, moisture meter, moisture meter, moisture detector, moisture measuring instrument, and moisture analyzer. It is mainly used to detect samples with low moisture content. After continuous improvement, its accuracy has been greatly improved and the measurement range has been expanded.

[0003] To this end, technicians in the relevant technical field have made improvements. For example, Chinese patent publication No. CN221351303U proposes a "trace moisture meter that is convenient and quick to fix", which includes: a trace moisture meter body, a fixing mechanism is installed on the top of the trace moisture meter body, and the fixing mechanism includes a support rod, which is fixedly installed on the top of the trace moisture meter body, and a fixing frame is fixedly installed on the top of the support rod. A sliding structure is installed inside the fixing frame, and an extension plate is fixedly connected to the front of the fixing frame. A column is fixed on the top of the extension plate, and two connecting rods are rotatably connected to the outside of the column. An arc plate is fixed on the bottom of the connecting rod away from the fixing frame, and a connecting rod is hinged on the side of the connecting rod away from the arc plate. Although the above-mentioned fixing mechanism can meet the requirements of clamping the bottle body of the glass bottle, it is simple to operate and convenient and quick to fix.

[0004] However, its structure is relatively complex, and it cannot evenly wrap the surrounding area of ​​the bottle, which may cause it to become loose and fall off.

[0005] Based on this, it is necessary to propose a fixing mechanism that has a simple structure and is more fully and stably fixed to the bottle body. Utility Model Content

[0006] The purpose of the present invention is to provide a convenient and fast fixed trace moisture meter for detecting the moisture content of MMDS, so as to solve the above technical problems to at least a certain extent, reduce the complexity of the structure, facilitate the fixation of the bottle body and maintain sufficient stability.

[0007] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: comprising a detection unit, a fixing unit and a limiting unit, wherein the detection unit comprises a body, a detection mechanism provided on the upper part of the body, a connecting pipe and a display screen on the body for operation;

[0008] The fixing unit includes a blocking rod, a movable rod and a spring, wherein the connection between the blocking rod and the movable rod is fixedly connected to the top of the body, one end of the spring is fixedly mounted on the top of the body, and the other end of the spring is fixedly mounted on the side of the movable rod away from the blocking rod;

[0009] The limiting unit includes a limiting block installed on a side of the movable rod close to the blocking rod, an interference block installed at a position opposite to the limiting block, and a limiting ring sleeved on the movable rod.

[0010] Preferably, the tail of the blocking rod is arranged in an arc shape downward.

[0011] Preferably, the movable rod is arranged in a certain arc.

[0012] Preferably, there are a plurality of movable rods, which are evenly arranged and installed with the detection mechanism as the center, and each of the movable rods is connected with a spring on one side.

[0013] Preferably, the side area of ​​the limiting block is larger than the side area of ​​the limiting ring, and the space between the two limiting blocks is larger than the side area of ​​the limiting ring.

[0014] Preferably, there are a plurality of the limit blocks, and the limit blocks are evenly arranged and installed on the side of the movable rod.

[0015] Preferably, the resistance block is made of a material having a certain toughness, such as rubber.

[0016] Preferably, one end of the movable rod on which the interference block is mounted faces the detection mechanism.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] When the utility model is used, the bottle body is placed on the detection mechanism, the movable rods are inserted into the limit rings one by one, and the limit ring is moved downward to between the two limit blocks according to the different diameters of the bottle body. The more the limit ring moves downward, the closer the top of the movable rod and the resistance block are to the bottle body. When the resistance block is in close contact with the bottle body, the limit ring is released, and the spring extends to push the movable rod outward. The movable rod generates an outward pulling force on the limit ring, and the contact between the limit ring and the limit block prevents the movable rod from being further pushed out by the spring. The bottle body can be fixed in multiple directions by the movable rod and the resistance blocks around the detection mechanism. The structure is simple, and it is convenient to fix and loosen the bottle body, and the fixation is more tight and stable. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] See also Figure 1-3 The present invention provides a technical solution: a convenient and fast fixed trace moisture meter for detecting the moisture content of MMDS, comprising a detection unit 100, a fixing unit 200 and a limiting unit 300. The detection unit 100 comprises a body 110, a detection mechanism 120 arranged on the upper part of the body 110, a connecting pipe 130 and a display screen 140 on the body 110 for operation. The detection unit 100 is a component of a conventional moisture meter and has no special improvements or changes, which will not be described in detail here.

[0029] The fixing unit 200 includes a blocking rod 210, a movable rod 220 and a spring 230. The connection between the blocking rod 210 and the movable rod 220 is fixedly connected to the top of the body 110. The connection between the blocking rod 210 and the movable rod 220 can be stably installed on the body 110, so that the blocking rod 210 and the movable rod 220 will not fall off or have angle deviation.

[0030] See Figure 1 and Figure 3 In a preferred embodiment, the tail of the blocking rod 210 is set in an arc shape downward, and the movable rod 220 is set in a certain arc. Both the movable rod 220 and the blocking rod 210 have a certain toughness and deformation ability, and can be applied with forces at multiple angles and can recover. One end of the spring 230 is fixedly mounted on the top of the body 110, and the other end of the spring 230 is fixedly mounted on the side of the movable rod 220 away from the blocking rod 210. When the spring 230 extends toward the movable rod 220 to release the elastic potential energy, the upper half of the movable rod 220 can move to a certain extent toward the blocking rod 210. At this time, the blocking rod 210 plays a role in maintaining its stability and preventing the movable rod 220 from angular deviation. The certain arc setting of the movable rod 220 makes it so that except for the contact block 320 part which contacts the bottle body, other parts do not contact the bottle body.

[0031] See Figure 1 、 Figure 2 and Figure 3 , further preferably, there are several movable rods 220, and the several movable rods 220 are evenly arranged and installed with the detection mechanism 120 as the center. Each movable rod 220 is connected with a spring 230 on one side, and a resistance block 320 is installed at a position opposite to the limit block 310. One end of the movable rod 220 is installed with the resistance block 320 facing the detection mechanism 120. The resistance block 320 is made of a material with a certain toughness such as rubber. The soft setting of the resistance block 320 can prevent damage to the bottle body. Through the several springs 230 and the movable rods 220, the resistance blocks 320 can be pushed toward the bottle body, thereby playing a role of limiting and fixing the bottle body from multiple angles.

[0032] See Figure 1 、 Figure 3The locking cam 330 is secured to the cam 332 and is easily retracted when the locking cam 332 is in a locked position.
