Referring to FIGS. 1 to 4, it is an embodiment of the new fixing device. In this embodiment, the fixing device includes two adjustable limit mechanisms 100 as an example, and is suitable for being installed in a loading position with an adjustable position. Structure 101. In this embodiment, the top side of the fixing device may cooperate with a mechanism such as a clip arm (not shown) to provide a fixing effect for printed circuit boards of different sizes and specifications. The loading structure 101 is an example of a rod-shaped structure in the figure, and the fixing device can slide on the loading structure 101 after releasing the locked state, so as to cooperate with different sizes of printed circuit boards for processing. In this embodiment, the adjustable limit mechanism 100 is implemented in a mirror-symmetrical manner, and the two are connected through an undetailed mechanism for matching use. According to different implementation forms, the fixing device can also be implemented by one or more of any number of adjustable limit mechanisms 100, and the type of the loading structure 101 is not limited to a rod-shaped structure, so it is not specific The implementation is limited. In order to clearly explain the content of this embodiment, in the following description, the adjustable limit mechanism 100 located on the right side of the drawing is mainly used for description.

Referring to FIGS. 2 to 5, each adjustable limit mechanism 100 includes a first clamping structure 1, a second clamping structure 2 and an elastic member 3.

The first clamping structure 1 is, for example, a plate-shaped structure made of metal, and a first clamping hole 11 is formed therethrough. The first clamping hole 11 is suitable for the loading structure 101 to penetrate. The second clamping structure 2 is, for example, a plate-shaped structure made of metal and one side (top side in the figure) is pivotally connected to the first clamping structure 1, so that the second clamping structure 2 can be relative to the first clamping structure 2 A clamping structure 1 pivots. The second clamping structure 2 penetrates to form a second clamping hole 21 corresponding to the first clamping hole 11, the size of the second clamping hole 21 is different from that of the first clamping hole 11, and the second The clamping hole 21 is suitable for penetrating the loading structure 101 together with the first clamping hole 11. The elastic member 3 is connected to the first clamping structure 1 and the second clamping structure 2 and provides an elastic force that allows the second clamping structure 2 to pivot away from the first clamping structure 1 so that A part of the hole edge of the second clamping hole 21 is locked on the loading structure 101. Thereby, the positive force and friction force formed by the contact of the hole edge of the second clamping hole 21 (such as the hole edge at the bottom side in FIG. 5) with the loading structure 101 can limit the adjustable limit The position mechanism 100 and the loading structure 101 cannot move relative to each other arbitrarily. Therefore, the fixing device shown in FIGS. 3 to 5 can be set to the locked state, so that the fixing device cannot move on the loading structure 101. Of course, according to the design of the size of the first card hole 11, in the locked state, the hole edge of the first card hole 11 can also be configured to be locked on the loading structure 101, so that the first card hole 11. The hole edges of the second clamping holes 21 are all locked on the loading structure 101, which can better ensure the fixing effect.

Referring to FIGS. 1, 6 to 8, the second clamping structure 2 includes a pivoting portion 22 pivotally connected to the first clamping structure 1, and a pivoting portion 22 located in the second clamping hole 21 respectively The two opposite sides of the pressing portion 23. The pressing portion 23 is suitable for pressing against a device (not shown in the figure), so that the second clamping structure 2 can overcome the elastic force of the elastic member 3 as shown in FIGS. 6-8 to move closer to the first card The direction of the control structure 1 pivots so that the edge of the second clamping hole 21 and the first clamping hole 11 are not locked in the loading structure 101. In this way, the locked state of the fixing device can be released, so that the fixing device can be arbitrarily moved on the loading structure 101 to adjust the size of the printed circuit board to be processed.

Referring to FIGS. 1 to 3 and 5, in this embodiment, the size of the first clamping hole 11 is slightly larger than that of the loading structure 101, and the size of the second clamping hole 21 is larger than that of the first clamping hole 11. The first clamping hole 11 and the second clamping hole 21 have the same shape, and the shape can be selected from one of a circle, a square, and a polygon. In the figure, a square is taken as an example. Structure 101 is the same. Since the size of the second clamping hole 21 is configured to be larger than that of the first clamping hole 11, it is ensured that the second clamping structure 2 has a certain degree of moving space when pivoting, but it can still pass through the second The hole edge of the card-making hole 21 provides the effect of limiting the card engine. In different implementations, the first clamping hole 11 and the second clamping hole 21 may also have different shapes, as long as the hole edge of at least one of the two can be locked in the locked state The loading structure 101 can play a fixed role.

Referring to FIG. 1 to FIG. 4, the adjustable limit mechanism 100 further includes the inner side of one of the first clamping structure 1 and the second clamping structure 2 to the first clamping structure 1 and the second The other of the clamping structure 2 protrudes and supports the structure 4. In this embodiment, the supporting structure 4 protrudes from the inner side of the second clamping structure 2 toward the first clamping structure 1. Thereby, after the second clamping structure 2 pivots toward the first clamping structure 1, the supporting structure 4 will support the first clamping structure 1 and the second clamping structure 2 Therefore, the second clamping structure 2 cannot continue to pivot toward the first clamping structure 1. In this way, after the second clamping structure 2 is pressed in the direction of the first clamping structure 1, the supporting structure 4 can be provided between the first clamping structure 1 and the second clamping structure The supporting function prevents the second clamping structure 2 from being excessively pressed, thereby providing structural protection. In addition, in this embodiment, the elastic member 3 is disposed at the pivotal joint of the first clamping structure 1 and the second clamping structure 2 and the two ends are respectively connected to the first clamping structure 1 and the second clamping structure The torsion spring of the clamping structure 2 is used to provide the elastic force required to maintain the locking state of the fixing device and the adjustable limit mechanism 100. However, the elastic member 3 can also adopt members other than the torsion spring as needed, and is not limited to the disclosure in this embodiment.

Based on the above, the size of the first fixing hole 11 of the first clamping structure 1 and the second clamping hole 21 of the second clamping structure 2 of the novel fixing device may be further arranged through the size The shape design of the two enables the first clamping structure 1 and the second clamping structure 2 to be driven by the elastic force of the elastic member 3, and at least the edge of the second clamping hole 21 is locked for loading On the structure 101, the effect of limiting and fixing is achieved. When necessary, the locked state can be released by pressing against the second clamping structure 2, which is not only simple in operation, but also simple and uncomplicated in structure, which is beneficial to cost control and maintenance, and parts replacement. Therefore, the new fixing device and the adjustable limit mechanism 100 can indeed achieve the purpose of new cost.

However, the above are only examples of the new model. When the scope of the new model cannot be limited by this, any simple equivalent changes and modifications made according to the patent application scope and patent specification content of the new model are still regarded as Within the scope of this new patent.
