Embodiment Construction

[0020] see Figure 1-3 , in a preferred embodiment of the present invention, a fixing device includes an object to be fixed 10 and a fixing member 20 .

[0021] The object to be fixed 10 includes a fixing piece 11 . The fixing piece 11 includes an upper surface 13 and a lower surface 15 opposite to the upper surface 13 . The fixing piece 11 defines a stepped hole 110 . The stepped hole 110 includes a first fixing hole 111 and a second fixing hole 112 . The first fixing hole 111 and the second fixing hole 112 pass through the upper surface 13 and the lower surface 15 . The first fixing hole 111 communicates with the second fixing hole 112 . A stop surface 16 is disposed in the stepped hole 110 . In one embodiment, the first fixing hole 111 and the second fixing hole 112 are circular holes. The diameter of the first fixing hole 111 is smaller than the diameter of the second fixing hole 112 , so as to form the stop surface 16 . The stop surface 16 is located between the up...

Abstract

The invention discloses a fixing device which comprises a fixing plate and a fixing element, wherein a stepped hole is formed in the fixing plate, the fixing plate is provided with an upper surface and a lower surface which is opposite to the upper surface, a stopping face is arranged inside the stepped hole, the stopping face is arranged between the upper surface and the lower surface, the fixing element comprises a stopping part and a threaded part, the fixing element is movably fixed in the stepped hole, and the fixing element can move between a first position and a second position relative to the fixing plate. When the fixing element is in the first position, the threaded part extends from the stepped hole, and the stopping part abuts against the upper surface to prevent the fixing element from moving along the lower surface direction. When the fixing element is in the second position, the threaded part is held inside the stepped hole and abuts against the stopping face to prevent the fixing element from moving along the upper surface direction.

Description

technical field [0001] The invention relates to a fixing device. Background technique [0002] The locking method of fixing one object to another object by screws is very common in industrial production and daily life. Usually, holes are made on the object and another object, and then a suitable screw is found to pass through the hole of the object and locked into the hole of the other object. Sometimes a nut is required to be locked on the screw to prevent the screw from fall off. However, in such a locking method, the screw is separated from the object, and it is time-consuming and laborious to find a suitable screw when locking. And, when the nut is loose, the screw will fall from the object and be lost. Contents of the invention [0003] In view of the above, it is necessary to provide a fixing device that can prevent the screws from falling off. [0004] A fixing device, comprising a fixing piece and a fixing piece, the fixing piece is provided with a stepped hole...
