Benefits of technology

[0006] The present invention provides a clamping device. The clamping device provides a gear and a turning wheel that are coaxial. Hence, when both clamping elements are moved outwardly and inwardly to drive the gear, the turning wheel can be driven to rotate synchronously. Moreover, an impeding element limits both clamping elements from moving inward only for clamping an electronic device. Furthermore, when a release button is pressed, both clamping elements can be sprung out for releasing the electronic device. In addition, the present invention does not require two one-way ratchet wheels on both sides of the clamping elements. Hence, the entire structure of the clamping device's of the present invention is simple, and its manufacturing cost considerably less than that of the prior art.

Embodiment Construction

[0016] Referring to FIGS. 2-5, the present invention provides a clamping device, comprising: a seat body 1, two clamping elements 2, two springs 3, a gear 4, a turning wheel 5, an impeding element 6 and a release button 7. The seat body 1 has a front casing 11 and a rear casing 12. The front casing 11 and the rear casing 12 are locked or retained together via screws 13 to form a hollow casing. The rear casing 12 has a plurality of circular through holes 121 formed thereon and rectangular holes 122, both of the rectangular holes 122 communicate with both sides of each through hole 121, and the rectangular hole 122 has a width smaller than that of the through hole 121 for retaining a support board 14. The support board 14 of the seat body 1 has a plurality of protrusions 141 projected from one surface thereof and corresponding to the through holes 121. Each of protrusions 141 has two retaining portions 142 projected from both sides thereof, and there is a predetermined distance from a...

Abstract

A clamping device includes a seat body, two clamping elements, at least one spring, a gear, a turning wheel, an impeding element, and a release button. The seat body has a front casing and a rear casing. Each clamping element has a clamping body with a rack. The spring is disposed between the seat body and one of the two clamping elements. The gear and the turning wheel are pivoted in the seat body together. The gear is engaged with the two racks, and the turning wheel has a contact surface formed therearound. The impeding element is pivoted in the seat body, wherein the impeding element has an impeding surface that contacts the contact surface. The release button is movably disposed on the seat body and connected with the impeding element. Hence the clamping device's whole structure is simple, and the cost of the clamping device is reduced.

Description

BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention relates to a clamping device, and particularly relates to a clamping device adapted for clamping electronic devices, such as a GPS, a PDA or a cell phone, inside a vehicle. [0003] 2. Description of the Related Art [0004] Electronic devices, such as a GPS, a PDA, or a cell phone can be installed in a vehicle via a clamping device. Referring to FIG. 1, a known clamping seat 9 includes two seat bodies 91, 92, a fixed seat 93, and two clamping bodies 94 disposed on both sides of the two seat bodies 91, 92. The two clamping bodies 94 can be two support bodies for adjusting an electronic device's position and fixing the electronic device. The fixed seat 93 is disposed on a bottom side of the seat body 92, and is inserted into a cigarette-lighter's socket of a vehicle or fixed in the vehicle. Two compression springs 95 are disposed between two seat bodies 91, 92. The clamping body 94 is slid along a s...
