[0002] During the transportation of goods, the goods need to be fixed to ensure the stability of the goods during transportation and avoid tipping over and damage. Especially during braking, the goods are prone to shaking due to inertia.
[0003] In the prior art, drawstrings are usually used to fix goods. When some wooden goods such as furniture are fixed by drawstrings, gaskets need to be placed at the contact points of the drawstrings. During transportation, the goods are constantly shaken, and the movement of the goods when braking can easily cause the gaskets to shift and detach, thereby causing damage to the goods. At the same time, drawstrings and other fixing methods only limit the movement of the goods. When braking, the goods will move due to inertia, thereby increasing the pulling force of the drawstrings, which can easily increase the damage to the goods. Utility Model Content

The two clamp rods on the same slide are movably connected to the sides close to each other, and the resistance rod is fixedly connected with a plurality of resistance blocks on the side away from the clamp rod.
[0007] As a preferred technical solution of the utility model, a plurality of clamping blocks are fixedly connected to one side of the interference rod extending into the interior of the clamping rod, and a plurality of limit blocks that interfere with the clamping blocks are fixedly connected to the interior of the clamping rod.
[0008] As a preferred technical solution of the utility model, a guide bar is slidably embedded in one side of the abutment rod close to the clamping block, a spring is installed between the guide bar and the abutment rod, and the spring pushes the guide bar to abut against the clamping rod.
[0009] As a preferred technical solution of the utility model, one end of the guide bar extending out from the abutment rod is in a trapezoidal structure, and a pair of guide bars are provided.

When emergency braking occurs during transportation, the heavier goods will continue to move under the action of inertia, thereby driving the slide to move. The slide will push the first support rod on one side to compress, thereby compressing the air inside the second air cylinder and the first air cylinder, and the reaction force during compression is controlled to counteract the inertia force, thereby playing a buffering role for the goods and avoiding damage to the goods. At the same time, the gas pressure can be adjusted in advance through the screw rod, so as to facilitate buffering of goods of different masses, thereby facilitating the control of the buffering effect, avoiding small goods mass and large reaction force, or large goods mass and small reaction force, thereby ensuring the protection of the goods.

Before the clamping rod collides with the goods, the resistance rod is inserted into the inner side of the clamping rod, and the resistance block is fixedly connected to the resistance rod, so that it can well collide with the goods and increase the friction force. At the same time, the resistance block can be made of different materials according to different goods. When transporting wood, the resistance block made of rubber can prevent the wooden goods from being damaged, thereby increasing the adaptability to different goods. The clamping block will extend into two adjacent limit blocks, thereby limiting the sliding of the resistance rod and preventing the resistance rod from detaching. BRIEF DESCRIPTION OF THE DRAWINGS

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.
[0024] See also Figure 1-6 , the utility model provides a technical solution of a buffer clamping device:

There are an air cylinder 22 and a second air cylinder 25, the second air cylinder 25 has a second piston 26 that is sealed and slidably arranged inside, a first support rod 23 that is fixed to the second piston 26 that is slidably connected to the second air cylinder 25, one end of the first support rod 23 is in contact with the slide 4, the first air cylinder 22 has a first piston 24 that is sealed and slidably arranged inside, a screw rod 21 is threadedly connected to one end of the bottom plate 1 that is close to the first air cylinder 22, the screw rod 21 is rotatably connected to the first piston 24, and a connecting pipe 27 for communication is installed between the first air cylinder 22 and the second air cylinder 25.
[0027] One end of the screw rod 21 away from the first air cylinder 22 is in a "cross" shape, so that the screw rod 21 can be easily rotated, thereby facilitating the adjustment of the air pressure between the first air cylinder 22 and the second air cylinder 25.
[0028] The diameter of the first gas cylinder 22 is greater than that of the second gas cylinder 25 , and the volume of the first gas cylinder 22 is greater than that of the second gas cylinder 25 , so that the overall gas pressure can be controlled by controlling the first gas cylinder 22 .
[0029] The clamping rods 5 are in the shape of a right triangle, and two pairs of clamping rods 5 are parallel to each other, thereby increasing the stability during support.
[0030] When in use, a pair of bottom plates 1 are installed at the bottom of the compartment, and the cargo to be fixed can be placed between the two abutment rods 31 on the same slide 4. The motor 7 is started, and the motor 7 drives the screw rod 6 to rotate. The screw rod 6 pushes the clamp rod 5 to approach the cargo, so as to fit and fix the cargo.

[0031] Embodiment 2:
[0032] On the basis of the first embodiment, Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, the clamp rod 5 is connected to a resistance mechanism 3, which includes a resistance rod 31. The two clamp rods 5 on the same slide 4 are movably connected to the sides close to each other with resistance rods 31, and the resistance rod 31 is fixedly connected to the side away from the clamp rod 5 with multiple resistance blocks 34. The resistance blocks 34 can be made of different materials to adapt to different goods.
[0033] A plurality of clamping blocks 32 are fixedly connected to one side of the resistance rod 31 extending into the clamp rod 5, and a plurality of limit blocks 35 that abut against the clamping blocks 32 are fixedly connected inside the clamp rod 5, thereby limiting the pulling out of the resistance rod 31 and preventing the resistance rod 31 from moving upward due to the cargo.

[0035] One end of the guide bar 33 extending from the abutment rod 31 is in a trapezoidal structure. A pair of guide bars 33 is provided to facilitate the abutment rod 31 to be inserted into the interior of the clamping rod 5 .
[0036] During specific use, before the clamp rod 5 collides with the goods, the interference rod 31 is inserted into the inner side of the clamp rod 5, and the interference block 34 is fixedly connected to the interference rod 31, so that it can well collide with the goods and increase the friction. At the same time, the interference block 34 can be made of different materials according to different goods. When transporting wood, the interference block 34 made of rubber can prevent the wooden goods from being damaged. When the clamp rod 5 collides with the goods, it will push the interference rod 31 to slide inside the clamp rod 5, thereby compressing the guide bar 33, the spring 36 will be compressed, and the block 32 will extend into the two adjacent limit blocks 35, thereby limiting the sliding of the interference rod 31 and preventing the interference rod 31 from detaching.
