A holding device is provided, including a seat affixed with two clamping pieces. At least one of the clamping pieces can slide transversely towards or backwards from the other. Inside the seat, a gear set, a stop unit and a manual unit are included so that clamping pieces can synchronously slide. The slide-close movement of the clamping pieces is not hampered, while the automatic slide-open movement of the clamping pieces is hampered, which can only be activated by manual unit. In addition, a gradual open mode is used for opening the clamping pieces to release the clamped apparatus. The present invention provides a noise-free and convenient operation.

What is claimed is: 1. A holding device, comprising: a seat; at least two clamping pieces, being affixtures to said seat, able to slide transversely towards or backwards from each other for opening or clamping; a gear set, located inside said seat to enable said clamping pieces for synchronous slid
What is claimed is: 1. A holding device, comprising: a seat; at least two clamping pieces, being affixtures to said seat, able to slide transversely towards or backwards from each other for opening or clamping; a gear set, located inside said seat to enable said clamping pieces for synchronous sliding; a stop unit, located on one side of said gear set, further comprising at least a moveable stop gear for controlling said gear set to prevent said gear set from automatically sliding outward while allowing sliding inward; and a manual unit, located on one side of said stop unit, for releasing said stop unit from the prevention state so as to allow said gear set to slide outward. 2. The holding device as claimed in claim 1, wherein said clamping pieces further comprise resilient buffers. 3. The holding device as claimed in claim 2, wherein said resilient buffers are made of foam. 4. The holding device as claimed in claim 1, wherein said gear set comprises a first gear and a second gear, said first gear is engaged to said second gear, and both said first gear and said second gear have a smaller gear to engage to a tooth rack located at the end of one side of said clamping pieces. 5. The holding device as claimed in claim 4, wherein said stop unit further comprises a stop gear, a gear and a moveable gear, said stop gear is in general engaged to one gear of said gear set; when said clamping pieces automatically slide outward, said stop gear moves to engage said first gear and said second gear so as to stop said clamping pieces from further sliding outward; said gear is engaged to said stop gear, and said moveable gear can move transversely, and is disengaged from said gear except when said manual unit is operated to move to engaged to said gear. 6. The holding device as claimed in claim 5, wherein said seat further comprises a resilient piece inside so that said stop gear of said stop unit is in general engaged to one gear of said gear set. 7. The holding device as claimed in claim 5, wherein said seat further comprises a resilient piece inside so that said gear and said moveable gear of said stop unit are in general disengaged from each other. 8. The holding device as claimed in claim 1, wherein said manual unit comprises a moveable push piece and a resilient piece located on one side; said push piece comprises a tooth rack on one side to engage to said moveable gear of said stop unit. 9. The holding as claimed in claim 1, wherein said manual unit comprises a turning wheel partially exposed outside of said seat and a co-axial gear; said co-axial gear is engaged to said moveable gear of said stop unit; and said moveable gear can move along an arc path. 10. The A holding device, comprising: a seat; at least two clamping pieces, being affixtures to said seat, one said clamping piece being able to slide transversely towards or backwards from the other for opening or clamping; a gear set, located inside said seat to enable said clamping piece for sliding; a stop unit, located on one side of said gear set, further comprising at least a moveable stop gear for controlling said gear set to prevent said gear set from automatically sliding outward while allowing sliding inward; and a manual unit, located on one side of said stop unit, for releasing said stop unit from the prevention state so as to allow said gear set to slide outward.
