Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

As shown in fig. 1-2, a novel wire pressing device for a wire feeding box comprises a cam 1, a pull rod 2, two cam seat plates 3, a base 4, a pressing arm 5, an adjusting screw 6, a position display 7 and a spring seat 8. Cam 1 is connected with pull rod 2, cam 1 adopts a rotation axis 9 spacing connection between two cam seat boards 3, the user makes cam 1 around rotatory rotation to 2 application of force of pull rod, the lower extreme of two cam seat boards 3 all is connected with base 4, base 4 upper end is arranged in to holddown arm 5, be connected with reset spring 10 between holddown arm 5 and the base 4, reset spring 10 is located holddown arm 5 and leans on middle position, holddown arm 5 is equipped with bearing 11 in the one end of being close to cam 1, bearing 11 is spacing between two cam seat boards 3, cam 1's lower extreme pressure bearing 11, holddown arm 5 extends to and serves and is connected with adjusting screw 6 outside base 4, adjusting screw 6's upper end hookup location display 7, adjusting screw 6's lower extreme connection spring holder 8. Because the lower extreme of cam 1 compresses tightly bearing 11, the one end that compresses tightly arm 5 is close to cam 1 is fixed, compress tightly arm 5 plays the supporting role by the reset spring 10 of intermediate position, pull rod 2 drives cam 1 and rotates and make the lug 12 of cam 1 press at the intermediate position of compressing tightly arm 5, increase decurrent effort at compressing tightly arm 5 intermediate position, make the one end that extends to the base 4 of compressing tightly arm 5 swing downwards, after shifting out the effort that cam 1 applyed, reset spring 10 will compress tightly arm 5 and bounce, the one end that extends to the base 4 of compressing tightly arm 5 swings upwards. Therefore, the cam 1 is driven by the pull rod 2 to rotate in the forward and reverse directions, so that the position display 7 and the spring seat 8 on the pressing arm 5 swing up and down, and the lower end part of the spring seat 8 carries out line pressing operation.

Wherein, the cam 1 is provided with a convex block 12, the upper end surface of the pressing arm 5 is provided with a concave platform 13, and the cam 1 rotates to enable the convex block 12 to be correspondingly pressed at the position of the concave platform 13 of the pressing arm 5.

Wherein, a side surface or two side surfaces of the cam 1 is provided with a limit bulge 14, one or two cam seat plates 3 are correspondingly provided with a limit groove 15, the shape of the limit groove 15 is a circular arc taking the rotating shaft 9 as a central axis, and the limit bulge 14 is correspondingly limited in the limit groove 15. The moving range of the limiting projection 14 is limited by the limiting groove 15, and the cam 1 is prevented from over-rotating during forward and reverse rotation.

Wherein, still be equipped with between two cam seat boards 3 and assist connecting axle 16, two cam seat boards 3 are connected at the both ends of assisting connecting axle 16 to strengthen two cam seat board 3's steadiness.

The above embodiments are merely illustrative and not restrictive, and all equivalent changes and modifications made by the methods described in the claims are intended to be included within the scope of the present invention.
