The inner clamping jaws 12 include two inner clamping bodies 120 respectively disposed at two ends of the bottom of the first power source 11 and can be driven by the first dynamic power source 11 , for example, The position of the two inner clips 120 may be a lateral movement or a longitudinal movement, and the lateral movement may be a forward movement or a left and right movement, and the longitudinal movement may be an up and down movement.

As shown in FIG. 2 and FIG. 3, the inner side surface of each inner collet 120 has a cross-shaped recess 121, and each inner collet 120 has a claw shape, and the recess 121 is coupled to the end of the memory 20. The shape of the part 200 is designed.

The second power source 14 is respectively disposed at two side ends of the base 10, for example, the second power source 14 can be a two-pneumatic cylinder or a two-hydraulic cylinder, and the relative distance between the two pneumatic cylinders or the two hydraulic cylinders Can be adjusted.

The outer jaw 15 is coupled to the bottom of the second power source 14, the outer jaw 15 extends away from the base 10, and the outer jaw 15 is parallel to the inner jaw 12, for example, if the outer jaw 15 comprises The second external power source 14 is a two-pneumatic cylinder, and each of the outer clamps 150 is coupled to one end of each pneumatic cylinder block. The two pneumatic cylinders can respectively drive the two outer clamping bodies 150 of the outer clamping body 150. For example, according to the positions of the two outer clamping bodies 150, the two outer clamping bodies 150 may have a longitudinal movement or a lateral movement. The longitudinal movement can be an up and down movement, and the lateral movement can be a left-right movement or a forward-back movement.

A guiding groove 151 is defined in a side of each of the outer clamping bodies 150 facing the inner clamping body 120. The guiding groove 151 is received by the inner clamping body 120, and the guiding groove 151 enables the outer clamping body 150 to follow the internal clamping. The body 120 travels in the direction of extension. In addition, as shown in FIG. 3, when the internal jaw 12 is provided with a memory 20, and the memory 20 is to be inserted into a slot, or the internal jaw 12 is driven by the first power source 11, When the memory 20 is interposed, the two inner clamps 120 follow the guiding direction of the guiding groove 151, and move toward the slot direction or away from the slot direction.

Referring to FIG. 3, if a memory 20 is to be inserted into a slot of a motherboard, the memory 20 generally refers to various types or specifications of memory that may be used by the server or various types of computers.

If the second power source 14 is in the setting mode of the two air cylinders, the movement manner of the two outer clamps 150 may move synchronously or asynchronously, because the motherboard system is applied to In the server, the slot is distributed in a dense manner on the motherboard, so one of the elastic pins of any slot can be It can interfere with one of the elastic bayonet pins of the other slot, and the elastic latching pin can only be opened at a small angle, so the two outer clamping bodies 150 are not synchronously moved, that is, the two pneumatic cylinders are driven successively. The distance between the two outer clamping bodies 150 and the two outer clamping bodies 150 is also different.

If the outer jaw 14 has caused the resilient bayonet to disengage, the second power source 14 again drives the outer jaw 14 to return the outer jaw 14 to the initial position.

If the elastic latch is in the expanded state when the memory 20 is moved over the slot, the second power source 10 does not drive the outer jaw 14.

The base 10 and the base 13 are lowered or moved by a distance, and the memory 20 is inserted into the slot. If the memory board 20 is connected with the adapter board, the adapter board is inserted into the slot. The first power source 11 drives the inner jaws 12 to move the inner jaws 12 away from the ends of the memory 20 such that the inner jaws 12 no longer clamp the memory 20.

When the memory 20 or the adapter board is inserted into the slot, the elastic bayonet automatically latches the memory 20 or the adapter board. If the memory 20 has been inserted into the slot, the base 10 will return to the initial position or leave the motherboard and perform the next action.
