Detailed Description

The following description will further describe embodiments of the present invention with reference to the accompanying drawings and examples. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.

As shown in fig. 1-5, the utility model relates to a handheld screw locking machine with feeding, which comprises an upper shell 1, a lower shell 2, a telescopic sleeve 3, a chuck body 4, a feeding device and a locking device, wherein the upper shell 1 is connected with the lower shell 2, the telescopic sleeve 3 is connected with the lower shell 2, and the telescopic range is controlled by a second reset spring 7 and a guide steel ball 9; the chuck body 4 is connected with the telescopic sleeve 3, the chuck body 4 adopts a spring reset principle, and the chuck body 4 is controlled to open and close by a third reset spring 6, so that the problems of screw falling and guiding in the feeding process are solved;

the feeding device comprises a screw slideway 5 and a third reset spring 6, the screw slideway 5 penetrates through the upper shell 1, the lower shell 2 and the telescopic sleeve 3, when the telescopic sleeve 3 is compressed, the screw slideway 5 is disconnected, the working process can be effectively prevented, redundant screws fall off, the screw machine can be effectively protected, and the service life is prolonged; the third reset spring 6 is arranged in the chuck body 4, the chuck body 4 plays a role in positioning and guiding in the screw locking process under the state that the third reset spring 6 is compressed, and the chuck body 4 can prevent the screw which is just sent in from falling under the reset state of the third reset spring 6. When the feeding function is used, when the switch is loosened by fingers, the screw machine is separated from a product, the power head 10 stops acting, the telescopic sleeve 3 is reset, the chuck body 4 is reset, and when the screw slide way 5 is communicated, the screw can automatically fall to the chuck body 4.

The locking device comprises a second reset spring 7, a connecting rod 8, a guide steel ball 9 and a power head 10, wherein the second reset spring 7 and the guide steel ball 9 are installed inside the lower shell 2, the power head 10 and the connecting rod 8 are installed inside the upper shell 1, and the connecting rod 8 is connected with the power head 10. When the locking function is used, a user holds the screw machine by hand, the chuck body 4 is close to a screw hole of a product, the chuck body 4 is pressed down forcibly, the chuck body 4 is abducted, the telescopic sleeve 3 retracts, the connecting rod 8 can contact the screw, the switch 11 is pressed down by fingers, and the power head 10 is electrified to drive the connecting rod 8 and the screw to rotate, so that the screw is locked on the product.

Specifically, a switch 11 is arranged on the side surface of the upper shell 1, the switch 11 is connected with the power head 10, and a first return spring 12 is further arranged on the inner side of the switch 11.

The head of the extension rod 8 is in a cross bulge shape or an outer hexagonal shape.

The working principle of the technical scheme is as follows:

the realization of the feeding function: the switch 11 is in a natural state, the second return spring 12 is in a natural state, the screw slideway 5 is communicated, and the screw falls to the chuck body 4 from the top of the screw slideway 5 and is clamped at the chuck body 4;

and (3) realizing a locking function: the screw locking machine is held by a hand, the chuck body 4 is close to a screw hole of a product, the chuck body 4 is pressed down with force, the telescopic sleeve 3 retracts, the second return spring 7 is compressed to a certain state, the connecting rod 8 is made to contact with the screw clamped by the third return spring 6, the switch 11 is pressed at the moment, the first return spring 12 is in the compressed state, and the power head 10 is electrified and drives the connecting rod and the screw to rotate, so that the screwing and locking functions of the screw are realized.

The locking function and the feeding function can not be carried out synchronously, and the telescopic sleeve 3 has two positions and can realize the locking function and the feeding function when running to different positions.

The utility model has the advantages that:

the screw feeding device and the screw locking device are integrated, so that the volume and the weight of equipment are reduced, the volume and the weight of the equipment are reduced, the manufacturing cost is reduced, the use requirement on space is lowered, the carrying is more convenient, and the application range is wider; the spring is arranged in the chuck body, and the problems of screw falling and guiding in the feeding process are solved through the resetting principle of the spring.
