DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] See also Figure 1-5 As shown, the utility model is a sample holder that can be moved up and down, including a sample holder mechanism 3, the sample holder mechanism 3 includes a fixing seat 301, the fixing seat 301 is installed on the required working equipment through a flange 5, the fixing seat 301 is a rectangular structure, fixed at the center of the flange 5 by screws, and the fixing seat 301 is a hollow structure, and a through hole is also provided at the center of the flange 5. The hollow structure of the fixing seat 301 is connected with the through hole to form a connecting cavity, and a rotating shaft 4 extending to the front of the fixing seat 301 is provided from the connecting cavity.

[0027] The fixed seat 301 is externally sleeved with a mounting seat 3021, and a movable frame 304 is mounted on the mounting seat 3021. The mounting seat 3021 is square in shape as a whole, and a mounting groove is opened on one side thereof, and the mounting seat 3021 is sleeved on the mounting seat 3021 through the mounting groove. Outwardly extending frame plates 3051 are respectively mounted on the front ends of the upper and lower sides of the mounting seat 3021, and a guide shaft 3052 is connected between the front ends of the two frame plates 3051. The movable frame 304 is located between the two frame plates 3051, and the guide shaft 3052 is penetrated through the movable frame 304, so that the movable frame 304 can only move linearly up and down along the mounting seat 3021, and a support plate 306 is connected to the outer end of the movable frame 304.

[0028] The movable frame 304 is provided with a long slide, which is located on the side of the mounting groove facing the mounting seat 3021; ​​the end of the rotating shaft 4 is connected to a turntable 3031, which is also arranged in the mounting groove, and an eccentric wheel 3032 is installed on the side of the turntable 3031 close to the slide, and the eccentric wheel 3032 is slidably arranged in the slide.

[0029] Specifically, whenever the rotating shaft 4 rotates, it will drive the turntable 3031 to rotate, and the turntable 3031 will drive the eccentric wheel 3032 to move accordingly. At this time, the eccentric wheel 3032 performs a circular motion. Since the eccentric wheel 3032 is located in the slideway of the movable frame 304, the eccentric wheel 3032 will drive the movable frame 304 to move up and down along the mounting seat 3021, and the movable frame 304 will drive the support plate 306 to move up and down, thereby realizing the control of the up and down reciprocating motion of the sample holder.

[0031] When the movable frame 304 moves up and down, the pulley 323 will slide in the slide rail 3022, which is more flexible and more stable.

[0032] Specifically, one end of the rotating shaft 4 away from the rotating disk 3031 is connected to the transmission rod 2 , and one end of the transmission rod 2 away from the rotating shaft 4 is connected to the magnet seat 1 .

[0033] By controlling the magnetic force of the magnet seat 1 , the transmission rod 2 can be driven to rotate, and the transmission rod 2 drives the rotating shaft 4 to rotate, which can provide driving force for the rotating shaft 4 , thereby realizing the movable operation of the sample holder mechanism 3 .

[0034] The working principle of this utility model:

[0035] Whenever the rotating shaft 4 rotates, it will drive the turntable 3031 to rotate, and the turntable 3031 will drive the eccentric wheel 3032 to move accordingly. At this time, the eccentric wheel 3032 performs a circular motion. Since the eccentric wheel 3032 is located in the slideway of the movable frame 304, the eccentric wheel 3032 will drive the movable frame 304 to move up and down along the mounting seat 3021, and the movable frame 304 will drive the support plate 306 to move up and down, thereby realizing the control of the up and down reciprocating motion of the sample holder.
