Description of the Invention: [Technical Field] The present invention relates to a positioning device for an actuating cylinder which can drive a piston rod by air or oil pressure to perform various operations. The device can be retracted after the piston 4 is dry to the clamp position, and the piston is pressed against the piston so that the piston rod will not be lost due to the loss of the body. [Prior Art] Pressing, the cylinder is a common mechanical power component, and mainly uses gas pressure or fluid pressure as a power source, so that the body is pressurized and separated into two blocks by the piston inside the cylinder. Circulating in the room, through the storage of mines, and the transfer of the money, the driving of the cylinder can make the mechanical appliance produce a variety of different functions. The knowing green is mixed with the control (10) off, This kind of operation: the actuator cylinder for closing work often needs to be maintained at one or two. The temple valve must be closed when it is continuously closed or opened, and the point ' can keep the valve closed or opened. The actuator is corresponding to the cylinder. Keep the pressure between the fixed points on the fixed point, so the door is mainly used with the two airs, the adjacent two spaces are connected === holding the valve pressure or the air pressure as the power source, and the shaft of the maintenance cylinder can maintain the valve normally and enough The pressure drives the normal cause of the long-term financial change of the power source. It is said that the 1 f force of the power source has _, that is, the problem that the power source will be driven by the power source will gradually lose. So, the problem, so _There is a step in the valve that does not close. [Inventive content] The part that needs to be improved. 5 1313733 The purpose is to solve the conventional cylinder, because the I method holds the pressure, and the piston rod is not pre- In order to solve this problem, the present invention provides a problem. If the red is included, the active red includes a first fluid passage and a second fluid passage, and the second fluid passage is provided. - the second fluid passage is filled with gas or liquid pressure, by means of === body passage or f-device touch, and the gamma (four)_ is provided with the device set to active _, the positioning device comprises one of sliding === The piston is used to seal the movable slot: the bolt-body-elastic element's piston rod's second movement to the positioning position, the fixed-faced face card can be used to determine the tilting. The slot ίί source state will not The piston rod is generated due to the loss of the thickness. [Embodiment] The technical features of the present invention will be described in conjunction with the drawings. The actuating red includes a chamber 13 ΪΤ 1 内部 inside, and a head outside the cylinder 1 11 and a tail 12 2 each, there is a - fluid channel (1) and:! 13 is slidably disposed with a piston rod 2, and is provided with a iii12. The piston rod 2 includes a sliding shaft shackle 21' and a sleeve end is connected to the end surface of the piston 屮4. The opening 1 12 of the head 11 can be externally connected to other devices or devices, and the two fluid passages can be divided into 'derived fluid power sources (such as compression (four) or hydraulic oil), so that one of the 1313733 fluid passages Into, another current miscellaneous 1 produces displacement Weiliuliu County Liyuan, the piston 2 /, the moving piston rod 2 2 can be moved. The setting is at least shown, this day is going to be recorded as the moving cylinder 113, which should be The cylinder block 1 can be provided with at least a movable slot slidingly disposed on the movable m3 and placed in the movable slot 113. 'It includes 1 and can be locked to the movable; a piston of the positioning rod 3 2 is a month of the piston 3 A bolt 34 is sealed, and a shoulder portion 1 2 5 is formed by the opening of the 34-shaped elastic member 3 3 and the movable groove positioning Π 9π i 3 - side opening. "! 12 5 has a notch 1 1 5 penetrating, the piston ΐ 3 has a head 2 1 1, and the head 2 1 1 is displaced corresponding to the positioning device 21; the piston located at / when the plug rod 2; In the case of 212, the piston 21 is fixed. Referring to the figure to Fig. 4, the head 11 of the hair (9), === one end of the Seto ΐ? forms a shoulder with a notch 115. The notch 1 1 5 of the positioning 4 has a slightly larger than the positioning device ft such that the flow entering from the first flow 11 channel 1 11 = the movement 2 enters the movable groove ii 3 via the notch 1 1 5 'the said spring abuts against the bolt 3 4 and the piston 3 of the positioning device 3 produces a 1 1 and the elastic member 3 3 allows the positioning rod 32 to be constantly extended beyond the notch 115 of the shoulder 114. The _ indicates that the piston rod 2 is in a retracted state, and the second fluid passage 121 of the cylinder 1 is required to be charged into the power source, and (4) the fluid passage ii is the fluid power source originally located in the chamber 3 Deriving the red body, so that the piston 2 x and the piston 1313733 = 2 can be pushed apart while being displaced, such as the head of the first body = ^ 2 1 abuts against the cylinder pressure, so that the elastic element ί ii side When the internal force of the chamber 13 is 3, the localized stress of the positioning device 3 is greater than the internal pressure of the chamber 13 and the outside of the chamber 1 is 5, and the pan-mu, 壬, 〇 2 can extend the shoulder 1 1 4 gap 1 ^ 1 l !:m 211 212 til 2 2 moving cup 2 2 - displacement internal transmission, report ▼ device 3 to fix the piston rod 2: position indication = yes::: =』: page arrived , 31 and the positioning rod 3 2 often maintain the outer side of the =, but if the first fluid passage 1 Η passes into the fluid movement 2, the internal pressure of the chamber 13 at the head portion 11 is greatly increased, as the first: the introduction of the pressure can be by the piston 21 The notch 115 of the ring groove 2 12 of the head 2 11 enters the movable groove 113, and the elastic stress of the elemental piece 3 3 causes the positioning rod 32 to be inserted into the groove 9 1 and the groove 1 1 3 Unlocate 32 to retreat. In the locked state of 21, the step-by-step can push the piston 2 i and the shaft 2 2 to be erected by at least the setting of the positioning device 3, which can effectively prevent the living internal chamber 13 from losing pressure and causing unpredictable movement, resulting in plugging #相连接的装置或设备 产生 Unpredictable action. As described above, the present invention is an excellent creation, and it is in accordance with the requirements of the invention and the application for the law. 1313733 BRIEF DESCRIPTION OF THE DRAWINGS The first drawing is a cross-sectional view of a cylinder of the present invention.
