Preferably, two guide rods 4d are provided. The main function of the guide rod is to limit the moving direction of the clamping plate, so that it can only slide in the width direction of the cart, and cannot deviate or tilt. This ensures that the clamping plate can remain stable when fixing the fire extinguisher, and prevents unnecessary shaking or shaking of the clamping plate during movement or operation of the cart, thereby ensuring the stability and accuracy of the fixing process, and also providing precise movement guidance for the clamping plate to ensure that it does not deviate from the predetermined path during movement. The provision of two guide rods can evenly share the load of the clamping plate and the clamping block, thereby preventing deformation or damage caused by excessive stress on a single guide rod, and improving the reliability of the entire device.

The provision of the clamping plate driving mechanism can quickly achieve the fixation and release of the fire extinguisher, thereby improving the efficiency of the fire extinguisher transfer.

[0030] As shown in Figures 3 to 5 , the clamping surface of the clamping plate 4c is provided with a buffer pad 5. Preferably, the buffer pad 5 is made of rubber. Rubber is soft and wear-resistant, which can effectively prevent the clamping plate from directly contacting the metal surface of the fire extinguisher, thereby preventing scratches or wear on the surface of the fire extinguisher due to friction or extrusion. Rubber has good cushioning performance, which can absorb part of the pressure when clamping the fire extinguisher, thereby preventing the fire extinguisher from being deformed due to excessive clamping force. Rubber has a certain friction, which can enhance the friction between the clamping plate and the fire extinguisher, thereby preventing the fire extinguisher from slipping or loosening during movement of the cart. In addition, rubber has good elasticity, which can absorb the impact force generated during movement of the cart, thereby preventing the fire extinguisher from being damaged due to bumps or collisions.

[0031] As shown in Figure 3 and Figure 4As shown, the clamping block 4f and the inner stand plate 4e are detachably connected together through a dovetail structure, which includes a convex part provided on the back of the clamping block 4f and a groove on the inner stand plate 4e, and the convex part and the groove are in sliding fit. The design of the dovetail structure allows the clamping block to be quickly inserted into the groove on the inner stand plate, realizing quick assembly and reducing installation time and operation complexity. The detachable design of the dovetail structure allows the clamping block to be easily disassembled and replaced, facilitating maintenance and adjustment. The dovetail structure can provide a firm mechanical connection, ensuring that the clamping block will not loosen or fall off during the movement of the cart, thereby ensuring the fixing stability of the fire extinguisher. The sliding fit of the convex part and the groove can prevent the clamping block from shifting in the vertical or horizontal direction, ensuring the alignment accuracy of the clamping block with the clamping plate. The convex part and the groove of the dovetail structure form a mechanical lock, which can ensure the firm and reliable connection between the clamping block and the inner stand plate, avoiding loosening due to external force. The design of the dovetail structure allows the clamping block to be flexibly adjusted in position, adapting to different cart layouts or fire extinguisher specifications. The detachable design of the dovetail structure makes it possible to expand the function of the device, such as quickly installing when the number of clamping blocks needs to be increased. Preferably, the clamping surface of the clamping block 4f is a V-shaped groove, which is used to adapt to fire extinguishers 2 of different diameters. The design of the V-shaped groove can adapt to fire extinguishers of different diameters, thereby improving the versatility of the device and meeting the fixing needs of fire extinguishers of various specifications. The V-shaped groove can automatically adapt to the diameter of the fire extinguisher and provide self-centering action during clamping, ensuring that the fire extinguisher is centered in the clamping block and avoiding shifting. The design of the V-shaped groove can evenly distribute the clamping force on the circumference of the fire extinguisher, avoiding excessive local pressure and thereby reducing damage to the fire extinguisher. The V-shaped groove has a larger contact area with the surface of the fire extinguisher, which can provide sufficient friction to prevent the fire extinguisher from slipping or loosening during the movement of the cart.
