Abstract

A screw holding and dispensing device includes a casing, a number of elastic members latched on an inner sidewall of the casing, and a pressing member received by the elastic member. Each elastic member carries a screw, to release a screw, an external force is applied on the pressing member, the pressing member is driven to move out of the top elastic member, the pressing member moves down and drives out the lowermost screw from the bottom elastic member, and the screw slides into a corresponding screw hole.

First claim

What is claimed is:

1. A screw holding and dispensing device comprising:
a casing;
a plurality of elastic members latched on an inner sidewall of the casing and each elastic member defining a receiving space; and
a pressing member received in the receiving space of a top elastic member;
wherein at least one screw is received in each receiving space of each elastic members, the inner sidewall of the casing defines a plurality of grooves, a quantity of the grooves is the same as a quantity of the elastic members, each of the elastic members is latched in one of the grooves, when releasing the screw, an external force is applied on the pressing member, the pressing member is driven to move out of the top elastic member, the pressing member moves down and drives a below screw to move out of a corresponding elastic member, when the pressing member is driven to move into a next elastic member, a bottom elastic member releases the received screw, then the screw slides into a corresponding screw hole.

2. The screw holding and dispensing device according to claim 1 , wherein sizes of the plurality of the elastic members are the same.

3. The screw holding and dispensing device according to claim 1 , wherein the casing is hollow and cylinder-shaped, a top end and a bottom end of the casing are both open.

4. The screw holding and dispensing device according to claim 3 , wherein the casing further defines a slot, the slot is continuous from the top end to the bottom end of the casing.

5. The screw holding and dispensing device according to claim 3 , wherein the elastic member is hollow and a shape of an inverted cone, an upper end of the elastic member is latched in the groove, and a bayonet is formed on a lower end of the elastic member, the bayonet is elastic, and is used for supporting the pressing member or the screw received in the elastic member.

6. The screw holding and dispensing device according to claim 4 , wherein the pressing member is cone-shaped, the pressing member defines an operation member, the operation member is exposed out of the casing from the slot, when releasing the screw, the operation member is driven to slide in the slot, and the pressing member is driven to move down.

7. The screw holding and dispensing device according to claim 5 , further comprising:
a guiding member fixed on the bottom end of the casing and defining a through hole, wherein the through hole is used for guiding the screw to slide down, the through hole is aligned with the bayonet of the bottom elastic member, a diameter of the through hole is greater than a diameter of a nut of the screw.

8. The screw holding and dispensing device according to claim 1 , wherein the casing further defines two pin connection mechanisms, the casing is opened or closed along the two pin connection mechanisms.
