Detailed Description

Fig. 1-5 show the structure of the present invention, a nail feeding device, which comprises an outer tube 2, a screwdriver rod 1 inserted into the outer tube 2, a tail end cap 6 sleeved on the screwdriver rod 1, a thread screwed on the outer thread of the tail end of the outer tube 2 through the inner wall of the tail end cap 6, a movable lock catch 5 fixed on the tail end of the outer tube 2 through a pin 8, the screwdriver rod 1 passing through a lock catch hole 9 on the movable lock catch 5, two sets of concave chutes 10 on the screwdriver rod 1, and a convex block 11 between the two sets of chutes 10.

When the nail applying device is used: as shown in fig. 4, the short-tail screw can be held by the screw feeder; the long-tail screw can be held by the upper nailing device as shown in figure 5.

When the position that stretches out of screwdriver pole 1 needs to be adjusted, press the activity hasp 5 of protrusion at outer sleeve pipe 2 this moment, just can manual pulling screwdriver pole 1 this moment, the position of spout 10 in the adjustment screwdriver pole 1, when being located the position of activity hasp 5 with the spout of front end, the device can join in marriage the dress short tail nail this moment, when being located the activity hasp 5 with the spout of the rear end of screwdriver pole 1, the device can join in marriage the dress long tail nail this moment.

According to the utility model discloses a further embodiment, include, movable lock catch 5's upper portion has waist shape hole 12, and pin 8 passes waist shape hole 12, and the internal diameter of hasp hole 9 is crossing to form for two circles, and the radius of the circle on upper portion is greater than the radius of the circle of lower part, and the radius of the circle of lower part equals the radius of spout 10, and there is bellied spring stopper 13 movable lock catch 5's bottom, and spring 7 cover is installed in spring groove 15 after on spring stopper 13.

When the screwdriver rod 1 is in the state shown in fig. 4, the movable lock catch 5 moves upwards to extrude the screwdriver rod 1 under the action of the spring 7, at the moment, the movable lock catch 5 is just positioned at the sliding groove 10 at the front end of the screwdriver rod 1, the screwdriver rod 1 can be fixed and is not moved, and at the moment, the short-tail screw can be held by the screw feeder. If the movable lock catch 5 is pressed downwards, the movable lock catch 5 moves downwards, the screwdriver rod 1 is in a loosening state, the screwdriver rod 1 is pushed forwards to the position of the screwdriver rod 1 (as shown in fig. 5), the movable lock catch 5 is loosened, the movable lock catch 5 moves upwards to extrude the sliding groove 10 at the rear end of the screwdriver rod 1, at the moment, the movable lock catch 5 is just positioned at the sliding groove 10 at the rear end of the screwdriver rod 1, the screwdriver rod 1 can be fixed and cannot move, and at the moment, the long-tail screw can be held by the screw feeder.
