The work it m is inserted into the outer cylinder in a freely movable manner and is placed above the spacer liJtiiaiM (four) Wei is pushed to the outer cylinder ' As a result, the pressure is lowered, and the pressure is formed. Therefore, the posture of the pressurized gas supplied to the gas passage is increased, and the moxibustion state is detected. [Prior Art Document] [Patent Document 1] Japanese Patent Publication No. 2003-305626 (Patent Document 3) Japanese Patent Laid-Open No. 2009-125821 [Explanation] [Problem to be Solved by the Invention] In the rod position detecting device of Patent Document 1, the detected portion is integrally attached to the clamping rod in the axial direction of 201233488. Because of the miniaturization, the rod position detecting device can not be used to make the peach-inspection device towel of the Mieda special document 2, and the prosecutor can be mounted on the movement amount smaller than the patent-track-detected portion. No. thousand fruit The neutral position L==The mast is kept in the card of the eight card. The piston rod and the detection are considered to be in the mobile end of the ship. The σ card is so complicated that it will also have the doubtfulness of the problem of the reliability of the operation. In the lever position detecting device of the fi and L, it is necessary to provide a switch or a sensor such as a switch or a sensor for detecting the detected portion, and the sensor is assembled to the clamp body. Therefore, in order to make the live, the Xiegan is more oriented toward the axis than the cylinder. The end side is protruded, and the detected portion is attached to the protruding portion of the rod to make the == ramie closer to the proximal end side in the axial direction, and the configuration of the rod position detecting device is in the position of the rod position in the patent document 3 'setting the detecting member, detecting The hole and the gas passage are detected by the pressure change of the pressurization (4) supplied to the body passage, and the thin direction of the screw is detected. However, it is difficult to make the closed portion of the detecting member close to the detecting hole of the central body side member. The circumferential surface. That is, it is difficult to make the position of the rod through which the gas passing through the pin hole is formed by the _ member of the _ member. In short, there is no way to improve the position detection of the clamping rod. Here, in order to close the closed portion of the detecting member that integrally moves with the clamp lever to the circumferential surface, the passage end through which the gas having the opening is formed is surely closed, and it is difficult to clamp The rod biases the detecting member in the direction orthogonal to the axis. Therefore, in order to improve the position detection accuracy of the clamping lever, it is necessary to improve the machining accuracy of the outer peripheral surface of the closing portion and the peripheral surface. However, the manufacturing cost becomes high. Further, the 'clamp detecting device of Patent Document 4 is disposed outside the independent clamping device, and it is not possible to detect only the clamping state of the clamping lever.' 201233488 The object of the present invention is to detect the position of the clamping lever* Device, providing - levelable assembly = tight = 3 test = = loading: fine to detect the position of the clamping rod and improve the position detection [to solve the problem] 2 clear «device position detection a recording body with a tight body, a magnetic rod inserted into the clamping body in a retractable manner, and a rod driving machine detecting device for advancing and retracting the clamping rod, characterized in that: ^, and by] 曰± κ People's home decoration #位置检测a rod, the needle member is fixedly disposed on the aforementioned refreshing body; the direction is rotatably mounted on the rod supporting member and the _ toward the shaft center 1, 1 multi-moving amount 'and the rod linkage mechanism' causes the clamping rod to interlock with the detecting rod In order to make the aforementioned clamping production relatively move in the direction of the axial direction and to make the rotation of the detecting rod and the clamping rod retreat (10), the position of the rotation is upward (the effect of the invention), and the thickness of the hair rod is limited to the core of the towel. Lying freely on the rod-cutting member and positioning the rod r in a predetermined position or a plurality of positions in the advancing and retracting direction, so that the apparatus constitutes a shaft and the direction of the detection space is miniaturized, and the rod position is In addition to the above configuration, the invention is constructed under the material. Moved from the second type to the rod support member and the part of the detection rod is turned to #, the first and second fluid passages are connected to the housing portion; the second member of the second support member And the second fluid passage is discharged from the second fluid passage n to the pressure and the other is discharged; and the passage opening and closing portion is formed and i broken (four) - 1. The connection position of the second fluid passage is '', and (1) is rotated by the blocking position of the first and second fluid passages. According to this configuration, the pressure change of the pressurization is measured by the pressurized fluid supplied from one of the second fluid passages, and the position of the pressurization or the connection position is set to be tight. (2) In (1), the second fluid passage is formed in the rod supporting member and the detecting rod. According to this configuration, since the second member is formed in the lever member and the detection is performed, the second fluid passage can be provided so that the pressurized fluid can be reliably supplied or discharged from the second fluid passage. (2) In (2), in the description; j; the dry-draw structure member is formed with a sliding surface slidably abutting with the passage opening and closing portion, the female moving surface and the axial center, orthogonal, in the spur A passage opening portion that can communicate the second fluid passage is formed between a peripheral wall of the accommodating portion of the member and the passage opening and closing portion, and a passage end of the second fluid passage forms an opening in the sliding surface, and the second portion The fluid secret (10) has an opening formed on an outer circumferential surface of the passage closing portion, and includes a biasing device that biases the passage opening and closing portion to the sliding surface. According to this configuration, by the rotation of the passage opening and closing portion, the connection/interruption of the second fluid passage can be reliably performed. Since the detection operation does not move in the direction of the heart, the passage opening and closing portion can be easily biased to the sliding surface. The spring pressure device. According to the bomb, the closing portion can reliably close the passage end of the first fluid passage, and the second fluid passage can be blocked. By providing the elastic device, even if the sliding surface or the sliding surface is abutted The surface of the passage closing portion is roughened, and the passage opening and closing portion is used to surely make the secret end of the collision path, so that the precision can be improved without increasing the machining accuracy of the surface machining to the required level, and thus in terms of cost. It is beneficial. (4) In (3), the rod supporting member is assembled to the clamping body, and the rod driving mechanism has a trajectory cylinder for clamping the jib crane, and the damper device presses the passage with a fluid pressure of the Wei fluid limb The opening and closing portion is configured to be biased to the sliding surface. According to this configuration, the rod supporting member can be assembled to the clamp body to densify the rod position detecting device. By borrowing the drive, the leaking test will be recorded before the _ move, 瞒, _ flow surface red fluid pressure, the fluid can be opened and closed to the sliding surface. (5) In the (3) towel, the spring device of the biasing device is constructed. According to this configuration, the passage flange can be reliably rotated by the spring member, and the clamp lever can be biased to drive the clamp rod forward. (4) The (1) towel is provided with a contact member, and the measuring member is thin. When the passage opening and closing portion is located at the blocking position, one of the passage ends of the second fluid passage is closed, and 201233488 and the second fluid passage are closed. The connection/shield of the passage end and the 流体2 fluid passage is actuated as described above in the manner in which the contact is opened. According to this configuration, it is possible to surely enter and break. In the ship, the passage opening and closing portion is formed in a rod shape, and the communication passage that connects the first and second back passages is formed to penetrate in the passage and the second fluid opening and closing portion to rotate, and the second fluid can be surely performed. The connection is broken. 'With the passage Jin 2~(7), the aforementioned clamping device is a rotary type of tensioning device with a conversion mechanism.
