Clamp mechanism

1. A clamp mechanism, comprising:

a base defining two first sliding grooves;

a sliding member slidable relative to the base and defining two second sliding grooves which are corresponding to the first sliding grooves, respectively;

a pair of first connecting members slidably received in the first sliding grooves respectively;

a pair of second connecting members slidably received in the second sliding grooves respectively;

a first clamp member connected to one first connecting member and one second connecting member;

a second clamp member connected to the other first connecting member and the other second connecting member;

an impelling member fixed to the sliding member; and

a driver capable of driving the sliding member to drive the first, second clamp members to move toward or away from each other to clamp or release an object, respectively, and the impelling member capable of removing the object when releasing the object.

2. The clamp mechanism of claim 1 , wherein the first sliding grooves, the second sliding grooves, the first and second clamp members are symmetrically configured relative to the moving direction of sliding member, and the impelling member is positioned between the first and second clamp members.

3. The clamp mechanism of claim 1 , wherein the first sliding grooves are substantially perpendicular to the moving direction of the sliding member, and the second sliding grooves are arranged at an oblique angle relative to the first sliding grooves and cooperatively forming a “V” shape.

4. The clamp mechanism of claim 1 , wherein the driver is a linear driver and comprises a cylinder fixed to the base, a third connecting member driven by the cylinder, and the third connecting member is fixed to the sliding member.

5. The clamp mechanism of claim 1 , wherein the impelling member extends linearly, the base further defines a guiding groove, the impelling member slidably engages in the guiding groove, and the second sliding grooves are symmetrically located relative to the impelling member.

6. The clamp mechanism of claim 1 , wherein the base further defines a pair of receiving grooves communicating with the first sliding grooves respectively, the first and second clamp members are partially received in the corresponding receiving grooves respectively.

7. The clamp mechanism of claim 6 , wherein the first and second clamp members both have a “ ” shape.

8. The clamp mechanism of claim 1 , wherein the sliding member and the impelling member are integrally formed.

9. The clamp mechanism of claim 1 , wherein the driver is located on a first side surface of the base, the first and second clamp members are positioned on a second side surface of the base opposite to the first side surface.

10. The clamp mechanism of claim 1 , wherein the first and second clamp members and the impelling member are substantially located in one plane.

11. A clamp mechanism comprising:

a base defining two first sliding grooves horizontally and a guiding groove substantially perpendicular to the sliding grooves;

a sliding member slidable relative to the base and defining two second sliding grooves arranged at an oblique angle relative to the first sliding grooves;

a pair of first connecting members slidably received in the first sliding grooves respectively;

a pair of second connecting members slidably received in the second sliding grooves respectively;

a first clamp member connected to one first connecting member and one second connecting member;

a second clamp member connected to the other first connecting member and the other second connecting member;

an impelling member fixed to the sliding member and slidably engaging in the guiding groove, the impelling member being positioned between the first and second clamp members; and

a linear driver capable of driving the sliding member to drive the first, second clamp members to move along the first, second sliding grooves such that the first, second clamp members move toward or away from each other to clamp or release an object, and the impelling member capable of moving upward away from the object or downward toward the object when clamping or both releasing and removing the object, respectively.

12. The clamp mechanism of claim 11 , wherein the first sliding grooves, the second sliding grooves, the first and the second clamp members are symmetrically configured relative to the moving direction of the sliding member.

13. The clamp mechanism of claim 11 , wherein the first sliding grooves are substantially perpendicular to the moving direction of the sliding member, and the second sliding grooves are arranged at an oblique angle relative to the first sliding grooves and cooperatively forming a “V” shape.

14. The clamp mechanism of claim 11 , wherein the linear driver comprises a cylinder fixed to the base and a third connecting member driven by the cylinder, and the third connecting member is fixed to the sliding member.

15. The clamp mechanism of claim 11 , wherein the impelling member extends linearly, and the second sliding grooves are symmetrically located relative to the impelling member.

16. The clamp mechanism of claim 11 , wherein the base further defines a pair of receiving grooves communicating with the first sliding grooves respectively, and the first and second clamp member are partially received in the corresponding receiving grooves respectively.

17. The clamp mechanism of claim 16 , wherein the first and second clamp members both have a “ ” shape.

18. The clamp mechanism of claim 11 , wherein the sliding member and the impelling member are integrally formed.

19. The clamp mechanism of claim 11 , wherein the linear driver is located on a first side surface of the base, and the first and second clamp members are positioned on a second side surface of the base opposite to the first side surface.

20. The clamp mechanism of claim 11 , wherein the first and second clamp members and the impelling member are substantially located in one plane.
