It can protrude from the outer edges of the elastic arm 131 and the second connecting plate 13, and can have a function of snap fixing and elastic contact. A guiding surface 134 can be further formed between the locking portion 133 and the outer edge of the elastic arm 131. The guiding surface 134 can be a beveled surface or a curved surface, and can be used to guide the locking portion 133 to be smoothly fastened and fixed. Resilience to elasticity.

The link units 1 can be pivotally coupled to each other by the first pivoting portion 115 and the second pivoting portion 116 to form an elongated chain. The number of the link units 1 is not Restrictions can be appropriately increased or decreased depending on actual needs.

[Second embodiment]

Each of the link units 1 of the present creation can be shared, and the link units 1 have the functions of a start link unit, an end point link unit, and an intermediate link unit. Referring to FIG. 5 and FIG. 6 , the link unit 1 at the starting point and the end point can be respectively fixed to the two fixing bases 2 by using a snapping manner. The two fixing bases 2 each have a body 21 , and the seat body 21 can be flat. It can also be bent into an L-shaped plate shape, and its shape is not limited. The seat body 21 can be disposed in a suitable position (such as a casing or a movable member) on the machine tool by a combination or integral molding.

The base body 21 is convexly provided with two second latching members 22, and the two second latching members 22 are oppositely disposed, and protrude from the one side of the base body 21, and can be used to buckle the start point and the end point of the first link unit 1 Card connector 14. In this embodiment, the second engaging member 22 is bent in an L shape to have a better guiding and limiting effect, that is, the second engaging member 22 can have a side plate 221 and an end plate 222. The side plate 221 is formed by vertically extending from one side of the seat body 21, and the end plate 222 is vertically formed by an end of the side plate 221 away from the seat body 21, so that two The end plates 222 of the two clips 22 extend toward each other.

Preferably, but not limited to, a protrusion 23 is protruded from the one side of the seat body 21, that is, the stop portion 23 and the two second clip members 22 protrude from the seat. On the same side of the body 21, the stopping portion 23 is adjacent to one end (end) of the two second engaging members 22. The shape of the stopping portion 23 is not limited. In the present embodiment, the blocking portion 23 has a square shape and is formed in a curved shape, which can be used to provide the effect of the link unit 1 to stop positioning.

The positioning body 24 is provided with a positioning hole 24, and the positioning hole 24 is located between the two second clamping members 22. The positioning hole 24 is a perforation corresponding to the locking portion 133. The shape of the positioning hole 24 is not limited. In the embodiment, the positioning hole 24 has a square shape.

The two first engaging members 14 of the link unit 1 of the starting point and the ending point can be respectively engaged with the corresponding two second engaging members 22 along a mounting direction A (as shown in FIG. 5 and FIG. 6 ), and second The inner side of the side plate 221 and the end plate 222 of the engaging member 22 can provide a good guiding and limiting effect of the first engaging member 14. When the two first engaging members 14 of the link unit 1 of the starting point and the ending point are engaged with the corresponding two second engaging members 22 to a predetermined position, one end of the second connecting plate 13 of the link unit 1 can interfere with each other. Positioning on the stopper portion 23 (as shown in FIG. 7) causes the link unit 1 to continue to move forward. When the first and second latching members 14 of the link unit 1 of the starting point and the end point are engaged with the corresponding two second latching members 22, the latching portion 133 can be buckled and fixed in the positioning hole 24, The link unit 1 of the starting point and the end point can be firmly fixed to the two fixing bases 2, and only the first engaging member 14 and the second engaging member 22 can be separated by pushing the locking portion 133 away from the positioning hole 24. The action of the above chain and the two fixing bases 2 constitute a chain device.

The chain of the present creation can be used to guide and protect the cables accommodated and to supervise the minimum allowable bending radius of the cables. The authoring chain is composed of a plurality of link units 1 pivotally connected to each other, and the link units 1 can share the functions of the starting link unit, the end point link unit and the intermediate link unit, and the starting point and the ending point. The link unit 1 is fixed in a snap-fit manner, and does not need to be fixed by screws, which is easy to assemble and save.

In addition, each link unit 1 of the present invention is provided with a resilient arm 131. The elastic arm 131 is provided with a locking portion 133. When used for the starting point and the end point link unit, the locking portion 133 can be buckled and fixed. The positioning hole 24 of the seat 2 can have a function of elastic snap fixing. When used in the middle link unit, the buckle portion 133 can elastically resist the bearing surface of the machine tool. Therefore, when the chain is in motion, each link unit 1 and the bearing surface are in small area contact, and have buffering and mute functions. Can reduce noise. This creation reduces the number of parts and also reduces costs and avoids assembly errors.

However, the above description is only the preferred embodiment of the present invention, and it is not intended to limit the scope of patent protection of this creation. Therefore, the equivalent changes made by using this creation specification and the contents of the schema are all included in the right of this creation. Within the scope of protection, it is given to Chen Ming.
