When the specimen pressing member 3 is opened, as shown in FIG. 1, a resilient force acts in the direction of arrow A, causing the specimen pressing member 3 to rotate clockwise. In the main body 1, a pin 9 is erected in the vicinity of the protruding portion 3 b of the sample pressing member 3, and the protruding portion 3 b abuts on the pin 9 to limit the clockwise rotation of the sample pressing member 3. . The sample pressing member 3 and the torsion spring 4 constitute sample pressing means.
[0011]
The main body 1 is provided with a first specimen abutting member 5 that can move straight in the specimen insertion direction in parallel with the body abutting portion 1a. A compression spring 6 is mounted between the first specimen abutting member 5 and the main body 1, and the first specimen abutting member 5 is urged toward the specimen 2 by an elastic force. The first specimen abutting member 5 is formed with a first protrusion 5 a and is engaged with the groove 1 c of the main body 1 to limit the movement range of the first specimen abutting member 5. In addition, a second sample abutting member 7 that is similarly movable in a straight line is disposed adjacent to the first sample abutting member 5. A compression spring 8 is mounted between the second specimen contact member 7 and the main body 1, and the second specimen contact member 7 is provided on the specimen 2 side and the first specimen contact member 5 side by elastic force. Is being energized. The second specimen contact member 7 has a notch 7b that is recessed and engages with the protrusion 3b of the specimen pressing member 3 to limit the movement range of the second specimen contact member 7. .
[0012]

The distance between the specimen abutting portion 3c and the main body abutting portion 1b of the main body 1 is sufficiently larger than the dimension of the specimen 2 in the longitudinal direction. Due to the elastic force of the compression spring 8, the notch 7 b of the second specimen pressing member 7 is in contact with the protrusion 3 b of the specimen pressing member 3 and protrudes to the specimen side from the first specimen pressing member 5. It is stationary.
[0014]
Next, as shown in FIG. 2, the specimen 2 is slid between the specimen abutting portion 3 c of the specimen pressing member 3 that is sufficiently wide and the body abutting portion 1 b of the main body 1, and the specimen abutting member 7. When is pressed, the notch 7b pushes the projection 3b of the specimen pressing member 3 to rotate the specimen pressing member 3. When rotated to some extent, the inflection point in the direction in which the elastic force of the torsion spring 4 acts is exceeded, the direction in which the sample pressing member 3 presses the sample 2 (direction of arrow B), that is, the torsion spring 4 counterclockwise. The resilience of will act. Further, when the specimen 2 is pushed into contact with the first specimen abutting member 5, the second protrusion 5 b falls into the notch 7 a of the second specimen abutting member 7, and the first specimen abutting member 5 The surface of the second sample contact member 7 that contacts the sample 2 is the same surface, and the sample 2 is held stationary. At this time, the specimen 2 is also in contact with the main body contact portions 1 a and 1 b of the main body 1.
[0015]
Next, when removing the specimen 2, as shown in FIG. 3, the specimen 2 is further pushed in the insertion direction. When the specimen 2 is pushed in, the first specimen abutting member 5 and the second specimen abutting member 7 move against the elastic force of the compression springs 6 and 8, respectively. The rear end portion 7 c of 7 moves along the inclined surface portion 1 d of the main body 1. Then, the second specimen abutting member 7 moves away from the first specimen abutting member 5, and the second protrusion 5b is detached from the notch 7a. If the hand is released from the specimen 2 in this state or the pressing force is loosened, the first specimen abutting member 5 and the second specimen abutting member 7 are caused by the elastic force of the compression springs 6 and 8, respectively. While extruding the specimen 2, the state returns to the state shown in FIG. 1, and the second specimen abutting member 7 stops at a position protruding from the first specimen abutting member 5. At this time, the protrusion 3b of the specimen pressing member 3 comes into contact with the notch 7b, the specimen pressing member 3 rotates, exceeds the inflection point of the elastic force of the torsion spring 4, and opens the specimen pressing member 3. An elastic force is applied in the direction of movement (the direction of arrow A in FIG. 1), and the protrusion 3b comes into contact with the pin 9 and stops.
[0016]
According to the present embodiment, the specimen can be easily attached and detached with a simple operation. In addition, since the distance between the contact portion of the specimen pressing member and the contact portion of the main body is sufficiently larger than the longitudinal dimension of the specimen, the accuracy during specimen insertion may be rough. Also, when taking out the specimen, it is only necessary to push the specimen once in the insertion direction.
[0017]
In the present embodiment, the rotation of the specimen pressing member is based on the elastic force of the torsion spring, but may be replaced with an elastic member such as a compression coil spring or rubber. Moreover, as shown in FIG. 4, the position applied to the specimen pressing member may be changed to replace the tension spring 4A. Further, a compression spring is used to bias the specimen abutting member, but it may be replaced with an elastic member such as rubber as long as the stroke can be secured.
[0018]
