[0026] Among them, a circular recess is integrally opened inside the upper end of the supporting tray 91, and the circular recess opened on the supporting tray 91 is connected to the card slot 92 opened inside, so that the circular recess opened inside the supporting tray 91 can cooperate with the internal three-side card slots 92 to realize the positioning and docking activities of the winding roller frame 5 as a whole; there are at least three card slots 92, and the card slots 92 are connected to the outer side of the bottom of the winding roller frame 5, so as to enhance the positioning and docking effect; the clamping components 93 are symmetrically arranged along the left and right card slots 92, and the pressure block 931 provided inside the clamping components 93 extends out of the supporting tray 91, so that multiple groups of clamping components 93 can conveniently realize the clamping and locking of the outer side of the lower end of the winding roller frame 5, thereby achieving a convenient locking effect.

[0027] See also Figure 3-5 The clamping assembly 93 in this embodiment includes a pressure block 931 that is movably embedded in the supporting tray 91 and can realize automatic clamping and locking, connecting strips 932 on the upper and lower sides of the side of the pressure block 931, and support rods 933 on the sides of the corresponding lateral connecting strips 932, so that the telescopic guiding state can be realized. The compression springs 934 that can provide elastic clamping support are correspondingly arranged at the outer ends of the support rods 933 on both sides, and a tightening structure 935 installed inside the pressure block 931 to improve the clamping firmness and avoid loosening problems.

[0028] The tightening structure 935 includes a screw 9351 which is vertically inserted into the support plate 4 and the pressure block 931, a limiting sleeve 9352 which is threadedly connected to the outside of the screw 9351, and a guide rod 9353 which is laterally inserted into the side of the limiting sleeve 9352. In this way, the limiting sleeve 9352 can be in a stable state under the laterally inserted guide rod 9353 to cooperate with the screw 9351 to realize the clamping and tightening activity, and an extrusion block 9354 which is connected to the lower end of the screw 9351 and is slidably connected to one side of the inner side of the pressure block 931. As a result, the extrusion block 9354 can rotate downward with the screw 9351 to realize convenient extrusion and locking transmission, and a slider 9355 which is relatively arranged at the lower end of the extrusion block 9354. The bottom of the slider 9355 slides against the bottom of the pressure block 931, and the connecting shaft 9356 is horizontally installed on the side of the slider 9355, and is fastened to the locking shaft 9357 on the side of the connecting shaft 9356 away from the slider 9355. The locking shaft 9357 passes through the side of the pressure block 931 and is inserted into the lower end of the winding roller frame 5, so as to achieve the clamping and tightening fit of the winding roller frame 5. Correspondingly, the limiting rod 9358 for transverse guidance is horizontally inserted into the upper end of the locking shaft 9357, and the fixing block 9359 is fixedly connected to the side of the limiting rod 9358 and connected to the inner side of the pressure block 931, and the spring 93510 installed on the outside of the limiting rod 9358 can provide elastic reset transmission support.

[0029] Among them, the outer surface of the pressure block 931 is set in a smooth inclined surface shape, and the pressure block 931 is symmetrically provided with a connecting strip 932, a support rod 933 and a compression spring 934 on the upper and lower sides away from the winding roller frame 5, ensuring that the pressure block 931 is automatically locked by the connecting strip 932, the support rod 933 and the compression spring 934 on the side; the front and rear sides of the limit sleeve 9352 are horizontally inserted with guide rods 9353, and the left and right ends of the guide rods 9353 on both sides are fixedly connected to the inside of the support tray 91, so as to Therefore, the limit sleeve 9352 is laterally connected to the guide rod 9353 on both sides, so that it can be stably located on the outer side of the upper end of the screw 9351, and stably realize the rotation and downward transmission activity of the screw 9351; the extrusion block 9354 and the slider 9355 are both arranged in a trapezoidal block shape, and the outer inclined surface of the extrusion block 9354 is opposite to the outer inclined surface of the slider 9355, ensuring that when the extrusion block 9354 is driven to move downward, it can be offset against the upper inclined surface of the slider 9355 to perform extrusion and horizontal pushing activities.

[0030] Here’s how it works:

[0031] When the winding roller frame 5 is to be quickly disassembled as a whole, it is necessary to first release the tightening structure 935 provided inside the pressure block 931 to tighten the clamping effect on the bottom of the winding roller frame 5, that is, by reversing the screw 9351 vertically inserted inside the pressure block 931, the screw 9351 is made to cooperate with the limit sleeve 9352 that is threadedly connected to the outer side of the upper end to rotate and move upward. In this way, the extrusion block 9354 connected to the lower end of the screw 9351 will move upward smoothly along the inner side of the pressure block 931, so that the extrusion block 9354 will move upward accordingly to release the extrusion effect on the slider 9355 provided at the bottom, thereby The spring 93510 on the outside of the positioning rod 9358 and in a compressed state will rebound and reset to automatically push the locking shaft 9357 inward, so that the locking shaft 9357 automatically moves into the inside of the pressure block 931, to automatically and conveniently release the plug-in effect with the lower end of the winding roller frame 5, so that the clamping and tightening effect of the winding roller frame 5 can be quickly released, and then, after the clamping and tightening state of the outer side of the tightening structure 935 on the other two sides is released, the winding roller frame 5 can be lifted as a whole to move the winding roller frame 5 out of the circular concave part inside the supporting tray 91 and the three card slots 92, thereby realizing the convenient disassembly and separation of the winding roller frame 5 and the support plate 4;

[0032] When the three ends of the bottom of the winding roller frame 5 are all inserted into the corresponding slots 92, the pressing blocks 931 on both sides of the extrusion groove 92 are pressed, that is, the pressing blocks 931 on both sides are moved into the two sides of the inner side of the supporting tray 91 in advance. At this time, the connecting strips 932 docked at the upper and lower ends of the side of the pressing block 931 will be connected to the support rod 933 on the outside to ensure the smooth inward movement of the pressing block 931. At the same time, the compression spring 934 on the outside of the support rod 933 will be squeezed. In this way, the rebound force of the compression spring 934 can indirectly push the pressing block 931 outward, so that the pressing block 931 is pressed against the bottom of the winding roller frame 5, so that the The pre-clamping combination of the winding roller frame 5 and the support disk 4 is achieved. In order to avoid the problem of loose connection between the winding roller frame 5 and the support disk 4 during the subsequent operation of the equipment, it is necessary to rotate the screw 9351 provided inside the tightening structure 935 to rotate the screw 9351 downward to push down the extrusion block 9354 connected at the bottom. In this way, the extrusion block 9354 will squeeze the slider 9355 opposite at the bottom to make the slider move horizontally and indirectly realize the external push of the locking shaft 9357 provided on the side, so that the locking shaft 9357 is inserted into the lower end of the winding roller frame 5 to achieve the clamping and tightening effect. At the same time, when the locking shaft 9357 is moved outward and inserted, the spring 93510 provided on the outside of the limit rod 9358 connected at the upper end will be squeezed to prepare for the subsequent automatic inward movement of the locking shaft 9357. Thus, the winding roller frame 5 can be conveniently disassembled and assembled as a whole without too many tedious steps.
