Abstract

A locking mechanism is disclosed. The locking mechanism includes a locking member, a guiding member, three engaging members, and an elastic member. Three receiving holes are defined in an outer side surface of the locking member. The guiding member is slidably and partly received in the locking member. The guiding member comprises a latching portion. Each engaging member is received in the corresponding receiving hole. One end of the elastic member resists against the guiding member, such that the engaging member is latched by the latching portion and partly protrudes out from the receiving hole.

Claims

1. A locking mechanism, comprising:

a locking member defining a through hole axially thereof, and at least one receiving hole defined in an outer side surface of the locking member communicating to the through hole;

at least one engaging member received in the at least one receiving hole;

a guiding member slidably and partly received in the through hole, the guiding member comprising a latching portion under the at least one engaging member; and

an elastic member received in the through hole, wherein one end of the elastic member resists against the guiding member, such that the at least one engaging member is latched by the latching portion and capable of partly protruding out from the at least one receiving hole.

2. The locking mechanism of claim 1, wherein each of the at least one receiving hole forms a positioning portion adjacent to the outer side surface of the locking member, and the at least one engaging member is latched between the positioning portion and the latching portion.

3. The locking mechanism of claim 2, wherein the positioning portion comprises a first resisting surface adjacent to the outer side surface of the locking member, and the first resisting surface is inclined.

4. The locking mechanism of claim 1, wherein a size of the receiving hole decreases along a direction away from the axis of the locking member.

5. The locking mechanism of claim 1, wherein a stop portion is formed on an inner side surface of the locking member, and opposite ends of the elastic member resist against the stop portion and the guiding member, respectively.

6. The locking mechanism of claim 1, wherein the locking mechanism further comprises a pressing member, and the pressing member is fixed to one end of the guiding member away from the latching portion.

7. The locking mechanism of claim 1, wherein a fixing hole is defined in a bottom surface of the pressing member, and one end of the guiding member away from the latching portion is fixedly received in the fixing hole.

8. The locking mechanism of claim 1, wherein the locking member is substantially a hollow conical frustum, an outer diameter of the locking member gradually increases in a direction away from the end of the locking member adjacent to the at least one receiving hole.

9. The locking mechanism of claim 1, wherein the locking mechanism further comprises a cover, the cover is securely positioned on the end of the locking member adjacent to the at least one receiving hole.

10. The locking mechanism of claim 9, wherein the latching portion defines a positioning hole, one end of the elastic member is received in the positioning hole, and resists against a bottom surface of the positioning hole, the other end of the elastic member resists against the cover.

11. The locking mechanism of claim 9, wherein the cover defines a through hole communicating to the through hole of the locking member.

12. A locking mechanism, comprising:

a locking member, the locking member being a hollow conical frustum, and a receiving hole defined in an outer side surface of the locking member communicating to the through hole, a size of the receiving hole decreases along a direction away from an axis of the locking member;

a guiding member slidably and partly received in the locking member, the guiding member comprising a latching portion;

an engaging member received in the receiving hole; and

an elastic member, wherein one end of the elastic member resists against the guiding member, such that the engaging member is latched by the latching portion and capable of partly protruding out from the receiving hole.

13. The locking mechanism of claim 12, wherein the receiving hole forms a positioning portion adjacent to the outer side surface of the locking member, the engaging member is latched between the positioning portion and the latching portion.

14. The locking mechanism of claim 13, wherein the positioning portion comprises a first resisting surface adjacent to the outer side surface of the locking member, and the first resisting surface is inclined.

15. The locking mechanism of claim 12, wherein a stop portion is formed on an inner side surface of the locking member, opposite ends of the elastic member resist against the stop portion and the guiding member, respectively.

16. The locking mechanism of claim 12, wherein the locking mechanism further comprises a pressing member, the pressing member is fixed to one end of the guiding member away from the latching portion.

17. The locking mechanism of claim 12, wherein a fixing hole is defined in a bottom surface of the pressing member, the end of the guiding member away from the latching portion is fixedly received in the fixing hole.

18. The locking mechanism of claim 12, wherein the locking mechanism further comprises a cover, the cover is securely positioned on the end of the locking member adjacent to the receiving hole.

19. The locking mechanism of claim 18, wherein the latching portion defines a positioning hole, one end of the elastic member is received in the positioning hole, and resists against a bottom surface of the positioning hole, the other end of the elastic member resists against the cover.

20. The locking mechanism of claim 12, wherein the latching portion is substantially a conical frustum.
