They are an indispensable and commonly used buckle tool for mountaineers and rock climbers. In addition, various carabiners are often used for various outdoor activities or for easily connecting various bags and accessories in life. The processing and production of carabiners are generally carried out by fully automatic equipment, and clamps are set at intervals along the circumference of the turntable of the processing equipment.

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in 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.

[0022] like Figure 1-Figure 4 As shown, a carabiner short section clamping mechanism comprises a base 31, a slide groove 311 is provided in the base 31, the slide groove 311 is in a "T" shape, a push block 2 is slidably installed in the slide groove 311, two rotating shafts 32 are provided on the base 31, and clamping blocks 33 are rotatably provided on the outer circumference of the rotating shafts 32, and clamping parts 30 are extended on the clamping blocks 33, and the other ends of the clamping blocks 33 are abutted and matched with the push block 2, and a first spring 34 is provided between the push block 2 and the base 31, and the first spring 34 always has a tendency to push the push block 2 to move toward the side close to the clamping block 33;

[0023] When the push block 2 moves toward the side close to the clamp block 33, the clamping portion 30 swings toward the side close to each other;

[0024] When the pushing block 2 moves to the side away from the clamping block 33 , the clamping parts 30 are caused to swing to the sides away from each other.

[0025] The installation is completed by installing the push block 2 into the slide groove 311, installing the first spring 34 between the base 31 and the push block 2, inserting the two shafts 32 into the clamping blocks 33 respectively, and finally fixing the shafts 32 to the base 31, which is more convenient.

[0026] The clamping blocks 33 are each provided with a connecting rod 35, and a second spring 36 is connected between the connecting rods 35. In the present application, the second spring 36 has connecting rings at both ends. When installed, the connecting rings at both ends are respectively sleeved on the outer circumference of the two connecting rods 35. The second spring 36 always has a tendency to swing the two clamping parts 30 away from each other, so that when the pushing block 2 and the clamping block 33 are out of contact, the clamping part 30 loosens the short section of the carabiner, so that the processed short section of the carabiner falls by itself due to gravity.

[0027] In addition, the elastic force of the first spring 34 is greater than the elastic force of the second spring 36, so that the push block 2 can always abut against the clamping block 33. Therefore, during the processing, the clamping part 30 always clamps the short section of the carabiner, so that the short section of the carabiner will not fall off during the processing.

[0028] The clamping parts 30 all have a clamping opening 331, the shape of which is adapted to the short section of the carabiner, so that the short section of the carabiner can be better clamped and fixed, and a rubber pad can also be installed on the surface of the clamping opening 331 to increase the friction when clamping the short section of the carabiner, so that the short section of the carabiner is more secure when clamped and will not fall off.

[0029] The clamping block 33 has a slope 332 at one end close to the pushing block 2, and the pushing block 2 has a pushing portion 22 at one end that abuts against the inclined groove 332. The pushing portion 22 is an isosceles trapezoid in the present application, and can also be an isosceles triangle in addition to the isosceles trapezoid, and there is an angle between the pushing portion 22 and the contact surfaces of the two slopes 332. When the clamping portion 30 is in a clamping state, the two clamping portions 30 contact each other, and at this time the angle between the two slopes 332 is a maximum value, and at this time the angle between the two slopes 332 is smaller than the angle between the pushing portion 22 and the contact surfaces of the two slopes 332, thereby ensuring that when the pushing block 2 is located at the extreme position close to one side of the clamping block 33, the angle between the two slopes 332 is a maximum value, thereby ensuring that the force of the clamping portion 30 when clamping the short section of the carabiner is a maximum value.

[0030] The pushing block 2 has a spring cavity 20 for positioning and installing the first spring 34 , so that the first spring 34 can be better positioned and installed.

[0031] A protrusion 21 is provided on the pushing block 2, and the pushing block 2 can be moved by pulling the protrusion 21. Furthermore, a connecting block 12 is provided on the protrusion 21, and the connecting block 12 has a hook 121 for pulling the protrusion 21 to move. The connecting block 12 is driven and connected to a driving member 1, and the driving member 1 is a cylinder. A connecting plate 11 is provided on the cylinder. The connecting block 12 is fixedly connected to the connecting plate 11, so that the movement of the connecting block 12 is driven by the cylinder, and then the hook 121 is driven to pull the protrusion 21 to move, and then the pushing block 2 is driven to move.

[0032] The installation steps are as follows: install the first spring 34 into the spring cavity 20, and then install the push block 2 and the first spring 34 into the slide groove 311. Insert the rotating shaft 32 and the connecting rod 35 into the clamping block 33, and fix the rotating shaft 32 to the base 31. Install the two ends of the second spring 36 on the two connecting rods 35 respectively to complete the installation.

[0033] When it is necessary to loosen the short section of the carabiner, the driving member 1 drives the connecting plate 11 to move toward the side away from the clamping block 33, thereby driving the connecting block 12 to move toward the side away from the clamping block 33, thereby driving the hook portion 121 to move toward the side away from the clamping block 33, so that the hook portion 121 contacts the protrusion 21, thereby pulling the protrusion 21 to move toward the side away from the clamping block 33, thereby driving the pushing block 2 to move toward the side away from the clamping block 33. At this time, the first spring 34 contracts to store elastic potential energy, and the second spring 36 releases the elastic potential energy, so that the clamping portion 30 on the clamping block 33 swings around the corresponding rotating shaft 32 toward the side away from each other, thereby achieving the effect of loosening the short section of the carabiner.

[0034] When it is necessary to clamp the short section of the carabiner, the driving member 1 drives the connecting plate 11 to move toward the side close to the clamping block 33, thereby driving the connecting block 12 to move toward the side close to the clamping block 33, and then driving the hook portion 121 to move toward the side close to the clamping block 33, so that the hook portion 121 is out of contact with the protrusion 21. At this time, the first spring 34 releases the elastic potential energy, thereby causing the protrusion 21 and the pushing block 2 to move toward the side close to the clamping block 33, and the pushing portion 22 of the pushing block 2 abuts against the slope 332 of the clamping block 33, thereby driving the clamping portion 30 on the clamping block 33 to swing around the corresponding rotating shaft 32 to the side close to each other, and the second spring 36 stores the elastic potential energy, thereby achieving the function of clamping the short section of the carabiner.
