Detailed Description

The invention will be further explained with reference to the drawings and the specific embodiments.

Example 1

As shown in fig. 1 and 3, the novel compasses comprise a compass head, a rotating foot, a positioning foot, the rotating foot, the top end of the positioning foot is relatively hinged on the compass head 1, a needle head 4 is embedded at the bottom end of the positioning foot, a cylindrical fastening cap 6 is sleeved at the bottom end of the rotating foot, a jack is opened along the extending direction of the length of the rotating foot at the bottom end part of the rotating foot for a lead core 5 to be inserted, a notch 24 is opened along the extending direction of the length of the rotating foot on the hole wall of the jack, if the notch is opened relatively on the hole wall, the movement allowance is increased, a threaded surface is opened on the wall of the top end cavity wall of the fastening cap, a corresponding position on the rotating foot is opened with a meshed threaded surface, from the top end to the bottom end, the inner hole diameter of the cavity of the fastening cap is gradually reduced, and therefore, in the process of sleeving the fastening cap, the hole wall of the fastening cap extrudes the peripheral wall of the rotating foot to change the hole diameter of the jack, and the lead core is fixedly inserted by clamping.

In the embodiment, the rotating foot is of a split structure and comprises an upper split body 21 and a lower split body 22, the lower split body is made of metal, the structural stability is improved, the lower split body is formed by injection molding, the cost is reduced, a lead core is conveniently clamped, a hole is formed in the top end of the lower split body so that a bottom protruding part of the upper split body can be sleeved in the hole, a screw is screwed in the hole in the side face of the lower split body, the upper split body and the lower split body are fixed into a whole through the screw, and a thread face, a first notch, a jack and the like are integrally formed when the lower split body is formed by injection molding.
