In order to hold the magnetic component with the tweezers, it is necessary to provide a space for accommodating the tweezers. In addition, during the movement of the clamping member, the contact surface of the recording member and the member is small, so that the member is liable to be inclined during the movement. SUMMARY OF THE INVENTION In view of the above, it is necessary to provide a clamp that is space-saving and smooth in motion. %' A clamping fixture' includes a first cylinder, a second cylinder, a push rod, a spring and a magnet. The first cylinder is a hollow cylinder with open ends, ί is provided with a large cylinder and a small cylinder, and the large cylinder and the small cylinder σ protrude from the inner surface of the first cylinder to form a convex with a through hole. station. The two cylinders are hollow cylinders, including a connecting end and a clamping end, and the connecting end is a second end, and the clamping end is used for holding an object. The push-pull rod is movably disposed in the first cylinder and the second cylinder, and the finger portion of the push-pull rod protrudes from the large cylinder. The elastic sleeve is sleeved in the first cylinder of the push-pull rod for providing an elastic restoring force away from the second rock body. The magnet is fixed to the other end of the push-pull rod and has a position of 7 200940264. The size of the magnet is larger than the size of the Langkong. The gripping jig 'includes a first cylinder, a second cylinder, a push-pull rod, a spring and a magnet. The first cylinder is a crucible (four) having two ends open, and the first end and the second end are gradually reduced. The first body is a hollow cylinder 'including a connecting end and a clamping end, the connecting end being connected to the second end. The illuminating end is for holding an object. The push-pull rod is movably received in the first barrel and the second barrel, and the end of the push-pull rod forms a finger-shaped portion that protrudes from the first end. The elastic sleeve is sleeved on the push-pull rod and is accommodated in the fourth (fourth) for providing the push-pull rod with an elastic restoring force away from the second cylinder. The magnet is disposed at the other end of the push-pull rod to lie in the second cylinder, and the magnet is restricted by the second end to move in the second cylinder. Compared with the prior art, the clamping jig of the present embodiment uses the force of the magnetic force to clamp the clamped fixture to a predetermined position to be fixed by the clamp, and then applies force to the push-pull rod to separate the magnet from the clamped object. Because the contact area between the lost holding device and the object to be clamped is relatively high, the clamping process towel is clamped to maintain a smooth movement state, and no unnecessary space is required to accommodate the lost holding jig. [Embodiment] The following will be combined. The invention is further illustrated in detail in the accompanying drawings. As shown in Figures 1 and 2, it is a clamping jig provided by the first embodiment of the present invention. The clamping jig 1 () includes a biasing lever η, a guiding rod 12, a spring =, a magnet 14, a first cylinder 15, a second cylinder 16, and a cover 17. One portion of the urging rod 11 is movably received in the first cylinder 15, and the remaining portion of the shank extends out of the first cylinder 15. The majority of the guiding rod 12 is movably accommodated in the first cylinder 15 and small. Partly received in the second cylinder 16 , the spring 13 is sleeved on the guiding rod 12 and received in the first cylinder 15 . The magnet 14 is fixed to the end of the guiding rod 12 and located in the second cylinder 16 . The urging rod 11 is a cylindrical body having a pressing finger 111 at one end and an external thread 112 at the other end. The guide rod 12 includes a large circular body 121 and a small cylinder 122 which are concentrically arranged. The large cylinder 121 has an internal thread 1210 that mates with the external thread 112 of the urging rod 11. The spring 13 is sleeved on the small cylinder 122, and the magnet 14 is fixed to the small cylinder 122 away from one end of the large cylinder 121. The first cylinder 15 is a hollow cylinder which is open at both ends and includes a large cylinder 151 and a small cylinder 152 which are concentrically arranged, and a finger edge 153. One end of the large cylinder 151 forms a finger edge 153 to facilitate the application of force, and the other end is connected to the small cylinder 152. The large cylinder 151 is coupled to the small cylinder 152 on the inner wall of the large cylinder 151 to form a boss 154 having a through hole 1542 to restrict the range of movement of the spring 13 to the first cylinder 15. Two positioning holes 1530 are formed in the finger edge 153. The second cylinder 16 is a hollow cylinder having one end or both ends open, and includes a joint end 161 and a grip end 162. The connecting end 161 is for connection with a small cylinder 152 for holding the object to be clamped. The small cylinder 152 projects into the connecting end 161 of the second cylinder 16 such that the first cylinder 15 is connected to the second cylinder 16. When the second cylinder 16 is open at the end, a plurality of air outlets 1622 are provided on the side wall of the clamping end 162 in order to prevent damage to the clamping fixture 10 caused by air compression during use. 200940264 The shape of the cover body 17 is the same as that of the finger edge 153, and a circular hole 171 is formed in the cover body 17 so that the force applying rod 11 can pass therethrough, and one surface surface protrudes to form two positioning rods 170. The diameter of the circular hole 171 is larger than the diameter of the urging rod 11 and smaller than the diameter of the large cylinder 121. The positioning rod 170 cooperates with the positioning hole 1530 such that the cover body 17 and the finger edge 153 are connected to each other. The diameter of the circular hole 171 is smaller than the diameter of the large cylinder 121 to prevent the guide rod 12 from being pulled out from the first cylinder 15. Of course, the size of the first cylinder 15 can also be gradually reduced, that is, the size gradually decreases from the ® end to the other end. Of course, the urging rod 11 and the guide rod 12 are not limited to the cylindrical body of the embodiment, and may be other shapes such as a triangular prism, a quadrangular prism, or the like. Of course, the first cylinder 15 and the second cylinder 16 are not limited to the cylinder of the embodiment, and may have other shapes such as a hollow rectangular parallelepiped, a pentagonal cylinder or the like. Of course, the boss 154 can also be disposed on the inner wall of the small cylinder 152. Further, the first cylinder 15 may not be provided with the finger edge 153, and the holder 10 may omit the lid body 17. When assembling, first, the urging rod 11 is passed through the circular hole 171 of the cover body 17, cooperates with the internal thread 1210 to screw into the guiding rod 12, and secondly, the spring 13 is sleeved on the small cylinder 122 of the guiding rod 12. Then, the guiding rod 12 is extended into the first cylinder 15 (if necessary, if the guiding rod 12 is long and passes through the through hole 1542), the positioning rod 170 of the cover 17 is inserted into the positioning hole 1530. The cover 17 is fixed to the finger edge 153. Further, the magnet 14 is fixed to the small cylinder 122, and finally the second cylinder 16 is placed over the small cylinder 152. When the clamping member 10 is used to hold the component, the first cylinder 15 or the 200940264_first cylinder 15 and the second cylinder 16 are held, and the pressing finger 111 applies pressure to the urging rod 11*, and the magnet 14 will Under the action of the thrust, the second cylinder 16 is moved, and the magnetic force acting between the magnet 14 and the object to be clamped is adsorbed on the clamping end 162 of the second cylinder 16 and then clamped. The holding object is moved to the predetermined position, and a pulling force is applied to the urging rod 11. At this time, the magnet 14 is away from the object to be clamped, and the urging rod 11 is returned to the original position by the action of the spring 13. Since the illuminating fixture 10 is in surface contact with the object to be clamped, the contact area is large, and therefore, the movement process is smooth; in addition, the clamping jig 10 is directly in contact with the surface of the object to be clamped, and no additional space is required for accommodating the nip. Fixture 10. As shown in Fig. 3, it is a gripping tool 20 provided by a second embodiment of the present invention. The clamp jig 20 includes a push-pull rod 21, a spring 13, a magnet 14, a first cylinder 25, and a second cylinder 16. The push-pull rod 21 includes a large cylinder 211 and a small cylinder 212 that are concentrically arranged, and a finger 213. The pressing finger 213 is disposed on the large cylinder 211, and the spring 13 is sleeved on the small cylinder 212, and the magnet 14 is fixed to the end of the small cylinder 212. The structure of the first cylinder 25 is substantially the same as that of the second cylinder 15, except that the through-hole is not provided on the edge 253 of the finger. As shown in Fig. 4, it is a gripping tool 30 provided by a third embodiment of the present invention. The clamping jig 30 is substantially identical in structure to the clamping jig 10, and includes a urging rod 11, a guiding rod 12, a magazine 13, a magnet 14, a first cylinder 35, a second cylinder 16, and a cover 17. The difference is that the first cylinder 35 includes a first end 351 and a second end 352. The size of the first cylinder 35 is gradually reduced from the first end 351 to the second end 352, and the second end 352 is used for The two cylinders 16 are connected. The spring 13 is constrained by the second end 352 to be moved in the first cylinder 35. The size of the guiding rod 12 is less than or equal to the size of the second end 352 to make it available to the first cylinder 35 and the second cylinder. 16 sports.
