DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model.

[0020] Please refer to Figures 1-4 The portable screw feeder mainly feeds the electric screwdriver automatically and ensures that one screw is fed to the electric screwdriver every time during the conveying process. The portable screw feeder comprises a rack 01 and a separation assembly 02 and a storage hopper 03 installed in the rack 01. A conveying assembly 04 for transferring screws is installed between the storage hopper 03 and the separation assembly 02. A feeding assembly 05 for conveying the screws in the storage hopper 03 to the conveying assembly 04 is installed at the bottom of the storage hopper 03. When in use, the operator places a plurality of screws in the storage hopper 03. The feeding assembly 05 lifts the screws in the storage hopper 03 to the conveying assembly 04. The conveying assembly 04 moves the screws to the separation assembly 02. The separation assembly 02 separates the screws in the conveying assembly 04 one by one and conveys the single screws to the outside of the rack 01. In the actual production process, the separation speed of the separation assembly 02 can effectively match the production speed of the electric screwdriver. At the same time, the separation assembly 02 is equivalent to a switch set between the conveying assembly 04 and the electric screwdriver. When the electric screwdriver stops working, the separation assembly 02 stops working. The screws in the conveying assembly 04 cannot enter the electric screwdriver and can only be arranged and stacked in the conveying assembly 04. That is, the separation assembly 02 can make the electric screwdriver realize continuous production and interval production.

[0021] The conveying assembly 04 comprises a linear oscillator 06 installed on the rack 01. The conveying strip 07 is fixedly installed on the linear oscillator 06. The conveying strip 07 is installed between the storage hopper 03 and the separation assembly 02. The conveying groove 08 is arranged through the conveying strip 07. One end of the conveying groove 08 is connected with the storage hopper 03 in a penetrating manner. The other end of the conveying groove 08 is connected with the separation assembly 02 in a penetrating manner. When the screw enters the conveying groove 08, the screw moves to the separation assembly 02 under the action of the linear oscillator 06.

[0022] In order to prevent the screw into the conveying strip 07 inconsistent direction. Conveying strip 07 fixedly installed on the limit seat 09, limit seat 09 is provided with the width of the gap with conveying strip 07 adapt, when limit seat 09 by fastener fixedly installed on the conveying strip 07, conveying strip 07 is located in the gap. Limit seat 09 is horizontally installed on the cylinder 10, the output end of the cylinder 10 extends to the storage hopper 03 direction.
