Embodiment Construction

[0047] The following non-limiting preferred embodiments are only examples, through which other features and advantages of the present invention can be more clearly understood, and the present invention is described in detail below with reference to the following accompanying drawings:

[0048] Figures 1 and 2 show parts 1 and 2 respectively, and when they are combined together, they constitute the buckle 3 of the present invention shown in Figure 3 .

[0049] Part 1 has a rod cap 4 to which a rod 5 is connected transversely.

[0050] The rod cap 4 of the part 1 is in the shape of a disc with a shallow groove 6 which can accommodate a screwdriver bit or a coin, and which is used to drive the part 1 to rotate.

[0051] The profile of the rod 5 is substantially rectangular in cross-section, with two ribs 7 located at opposite corners of the rectangular cross-section of the rod 5 .

[0052] The opposite end of the rod 5 to the rod cap 4 has a stop disc 8 with an anti-slip surface...

Abstract

The fastener (3) comprises a first part (1) having a stem (5) and a head (4) attached to one end of the stem (5), and a second part (2) having two elastic feet (12) and a plate (11) from which the elastic feet (12) project transversely, the stem (5) being adapted to slide in an opening formed in the plate (11), the fastener (3) being adapted to assume a waiting position in which the first part (1) is held in the second part (2) by means of the stem (5) passing through the opening and clamping said plate (11) between a stop surface (9) and a tooth (10); a locking position; and an unlocking position.

Description

technical field [0001] The present invention relates to clasps with spaced and compressed elastic claws. More particularly, the present invention relates to snaps that lock into shaped holes. For example, these clips can fix a fixing element to a carrier having such shaped holes. Background technique [0002] French patent 2 761 127 describes a blind hole fixing with two deformable claws, which consists of two parts, the two elastic claws of the first part are in a relaxed state when there is no pressure, and can be inserted into a carrier In the hole, the second part has a fixed foot, which can be inserted into the first part, and the two parts can be locked on the carrier. The deformation claw of the first part is separated by the fixed foot and pressed against the hole wall of the carrier. superior. [0003] Press the fixed feet with a predetermined shape into the first part, so that the fixed piece is locked on the carrier along its axial direction, and the fixed feet...
