[0051] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

For example, a method or product comprising a series of technical features is not necessarily limited to those technical features clearly listed, but may also include other technical features that are not clearly listed and can be included in the method or product.

[0053] In the description of the present invention, it should be understood that the directions or positional relationships indicated by the terms "upper", "lower", "left", "right", "front", "back", etc. are based on the directions or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention. Among them, "upper" and "lower", "left" and "right", "front" and "back" are opposite directions.

[0054] In the description of the present utility model, it is necessary to understand that the technical features defined by the terms "first", "second" and the like with sequential concepts are only for the purpose of clearly describing the defined technical features so that the defined technical features can be clearly distinguished from other technical features, but do not represent such naming in actual implementation, and therefore cannot be understood as a limitation of the present utility model.

[0055] The present invention is described in detail below in conjunction with specific embodiments and drawings.

[0056] like Figure 1-10 The clamp shown includes a guide rail 100 , a first clamping portion 200 , a second clamping portion 300 , a supporting component 400 and a clamping mechanism 500 .

[0057] The guide rail 100 is a metal member in the shape of a flat bar.

[0058] The first clamping part 200 is fixed to the front end of the guide rail 100 by two pins. The first clamping part 200 includes a first frame 201, a first sheath 202 and a first liner 203. The first frame is 4 metal sheets. The first frame is covered with the first sheath, or the first frame is embedded in the first sheath, thereby making the first frame and the first sheath integrated into one. The first liner is combined with the first sheath, preferably by injection molding. The first liner is preferably made of hard plastic or bakelite. Generally, the first liner is softer than the first sheath and has greater friction.

[0059] The second clamping portion 300 is slidably sleeved on the guide rail 100 through its through hole and cooperates with the first clamping portion to clamp an object.

[0060] The second clamping part 300 includes a second frame 301, a second sheath 302, a second pad 303 and a damping block 304. The second frame 301 is a metal bending part, which has two symmetrical walls, and the upper ends of the two walls are provided with a slot 306. The second frame is covered with the second sheath, or the second frame is embedded in the second sheath, thereby making the second frame and the second sheath integrated into one. The second pad is combined with the second sheath, preferably by injection molding. The second pad is preferably made of hard plastic or bakelite. Generally, the second pad is softer than the second sheath and has greater friction.

[0061] The first pad 203 and the second pad 303 are opposite to each other and a clamping space is maintained between them. When clamping an object, the object is located in the clamping space, and the first pad 203 and the second pad 303 contact and clamp the object. In view of the material configuration of the first pad and the second pad, the clamped object can be protected. In particular, for objects made of softer materials such as wood, the first pad and the second pad contact and clamp the object to avoid damage to the surface of the contact part.

[0062] During use, the clamp will change its posture and be affected by external factors, causing the second clamping part to slide too fast along the guide rail. For example, when the guide rail is vertical and is touched by external force, the second clamping part will slide too fast relative to the guide rail. The second clamping part that slides too fast relative to the guide rail is out of control and is prone to accidents. Therefore, a damping block 304 is configured for the second clamping part. The damping block 304 is U-shaped and straddles the guide rail 100. The damping block is assembled to the second frame by two transverse pins. The two pins and the other three pins in the illustrated structure cross the first wall and the second wall to fix the shape of the second frame to ensure its shape. And it provides installation convenience for the clamping mechanism described below. An elastic element 305 acts on the damping block 304, and the elastic force of the elastic element causes the damping block to contact the guide rail. When the second clamping part slides relative to the guide rail, the damping block and the guide rail generate friction, which can prevent the second clamping part from sliding too fast along the guide rail and causing accidents.

[0063] In order to clamp the object, it is necessary to apply a clamping force to the second clamping part, which is usually achieved by operating the clamping mechanism. There are many ways to implement the clamping mechanism, and the protection scope of the utility model is not limited. However, the process of causing the second clamping part to clamp the object is described with the illustrated structure. In the illustrated structure, the clamping mechanism 500 includes a bracket 501, a stacked locking piece 502, an elastic element 503, a screw 505 with a handle 504, and a push-pull member 506. Among them, the bracket 501 is sleeved on the guide rail 100 and located between the two walls of the second frame 301. According to the assembly position shown in the figure, the relative position of the bracket 501 and the second frame 301 is determined during assembly before connecting the corresponding pins. The stacked locking piece 502 is located in the transverse hole of the bracket and is also sleeved on the guide rail 100. Accordingly, the stacked locking piece is like a component of the bracket. The stacked locking piece 502 is inclined and clamps the guide rail through the edge of the through hole of the locking piece, so that the bracket is positioned on the guide rail. In order to increase the reliability of the locking plate clamping the guide rail, an elastic element 503 such as a bent plate-shaped spring is supported on the locking plate. The screw 505 is assembled in the threaded hole at the upper end of the bracket 501, and the push-pull member 506 is assembled at the front end of the screw and clamped in the clamping groove of the second frame. As shown in the figure, the object between the second clamping part and the first clamping part is clamped by rotating the screw to push the second clamping part 300 closer to the first clamping part. The reaction force of the object on the second clamping part is transmitted to the upper end of the bracket through the screw, forming a clockwise torque on the bracket. This torque makes the locking plate clamp the guide rail more tightly, thereby achieving a greater clamping force. Reversing the screw, the clamping force becomes smaller, and the torque borne by the bracket also becomes smaller. When there is no clamped object, the bracket is not subjected to torque from the screw. At this time, relying on the assembly relationship and the elastic force applied to the locking plate by the elastic element, the locking plate is moderately clamped on the guide rail, and the clamping mechanism can slide freely and move the second clamping part on the guide rail, so as to quickly move the second clamping part.

[0064] As shown in the figure, the thickness of the guide rail is limited. When an object is placed between the first clamping part and the second clamping part, the object is easy to fall even if it is supported by the guide rail. Therefore, a support component 400 is arranged on the guide rail to expand the support for the object and avoid or reduce the object from falling. The support component 400 is arranged on the guide rail 100 and is located between the first clamping part and the second clamping part to support and stabilize the clamped object. Figure 11-16As shown, the support component 400 has a storage plate 401, and the upper side of the storage plate has a storage surface 402. The width of the storage surface (the dimension in the left-right direction) is greater than the thickness of the track so as to better support the object and keep the object stable. The lower side of the storage plate has a first clamp arm 403, a second clamp arm 404, a first guard plate 410 and a second guard plate 411 extending downward. The entire outline of the first clamp arm is located within the first guard plate, and a portion of the outline of the second clamp arm is located within the second guard plate. This can prevent the first clamp arm and the second clamp arm from being directly collided during operation, or they will be protected by the corresponding guard plates and not be damaged when they are collided. A first channel 405 extending in the front-to-back direction is maintained between the first clamp arm and the second clamp arm, and between the first guard plate and the second guard plate. The guide rail 100 is as shown in FIG. Figure 6-7 As shown, the first clamping arm 403 and the second clamping arm 404 are disposed in the first channel 405 and are located at both sides of the guide rail 100 and clamp the guide rail, so that the support component is reliably combined with the guide rail and the support component can be removed from the guide rail and can slide along the guide rail.

[0065] In order to reliably combine the support component with the guide rail, the first clamp arm 403 has a clamp block 406 clamped on one side of the guide rail. The side of the guide rail is provided with a groove 101 along its length direction, and the clamp block is located in the groove. In addition, due to the existence of the groove, the guide rail saves materials and reduces weight while ensuring its strength.

[0066] The support component 400 is configured to be detachably mounted on the rear end of the guide rail, which is beneficial for placing the first clamping part and the second clamping part together. The support component will not hinder the first clamping part and the second clamping part from being placed together, and the support component mounted on the rear end of the guide rail can prevent the second clamping part from slipping off the guide rail. Furthermore, when the support component 400 is mounted on the rear end of the guide rail, it and the first clamping part at the front end work together to hold the clamp like two feet. Figure 3 , Figure 5 As shown in the figure, the clamp is placed upright. Since the support component and the first clamping part have the largest span, the stability of the clamp when it is upright can be ensured. At this time, the bottom profile of the second clamping part is slightly higher to avoid contact with the work surface where the clamp is placed when moving along the guide rail and being hindered, ensuring that the second clamping part moves smoothly to clamp the object.

[0067] In the structure shown in the figure, a pin hole 102 is provided at the rear end of the guide rail, and the support member has a pin 407. Fig. 9When the pin 407 is replaced to the rear end of the guide rail, it is located in the pin hole 102. In the illustrated structure, the support component 400 has a second channel 408 that penetrates the storage plate, the second clamp arm 404 has an extension section 409, the pin 407 is located in the extension section and is located at the lower side of the guide rail 100, and when the support component is replaced to the rear end of the guide rail, the second channel 408 is sleeved on the guide rail 100. Accordingly, the support component can be clamped on the guide rail by the first arm and the second arm as shown in the figure, that is, the guide rail is penetrated in the first channel. It is also possible to pass the guide rail through the second channel, and the support component can be transposed and attached to the rear end of the guide rail, with the pin located in the pin hole.

[0068] In other embodiments, the clamping block of the first clamping arm in the illustrated structure is made into a pin shape, and can also be installed at the rear end of the guide rail in the same posture as shown in the figure.
