[0023] Further, the second connecting mechanism comprises:

[0024] The mounting space is arranged in the supporting plate;

[0025] The positioning frame is arranged in the mounting space, and the second sliding groove is arranged in the positioning frame;

[0026] The sliding block is arranged in the second sliding groove, and the supporting side plate matched with the sliding block is arranged in the second sliding groove;

[0028] The second locking structure comprises a rotating column arranged in the rotating groove, a pushing column eccentrically arranged on the rotating column, an insertion plate arranged on the cover plate, an insertion slot arranged on the support plate and matched with the insertion plate, an insertion rod connecting the insertion plate and the insertion slot, and a second elastic component connecting the insertion rod and the sliding block.

[0029] The second connecting mechanism is arranged in two, and the two second connecting mechanisms are symmetrically arranged on both sides of the support plate.

[0030] The second connecting mechanism can further improve the fixing effect of the drying cylinder body. The first connecting mechanism is installed first, and then the second connecting mechanism is installed. When the second connecting mechanism is installed, the cover plate is closed on the support plate. During the closing process, the rotating column is first rotated. At this time, the rotating column drives the pushing column to rotate. Since the pushing column is eccentrically arranged and the sliding block is in contact with the pushing column, when the pushing column is rotated to the position farthest from the sliding block, the insertion rod on the sliding block is retracted into the sliding groove. At this time, the insertion plate on the cover plate is inserted into the insertion slot. When the insertion plate is completely inserted into the insertion slot, the rotating column is counterclockwise rotated. At this time, the pushing column is rotated and pushes the sliding block to move. The sliding block pushes the insertion rod out of the sliding groove and passes through the insertion plate, thereby fixing the insertion plate in the insertion slot. The insertion plate is provided with a hole matched with the insertion rod. Since the second connecting mechanism is arranged in two and the two connecting mechanisms are symmetrically arranged on the support plate, the sliding member is fixed in the sliding groove by the cover plate, the top of the sliding member is blocked, the cover plate and the support plate are fixed together, thereby further fixing the drying cylinder body, effectively preventing the drying cylinder body from loosening when being vibrated, and effectively fixing and installing.

[0031] Further, the sliding block comprises a mounting portion and a moving portion arranged on the top of the mounting portion. The mounting portion is fixedly connected with the moving portion.

The insertion rod is provided with a second mounting cavity for fixing the second elastic component. The moving portion is in contact with the support side plate, and the end of the moving portion in contact with the pushing column is provided with an arc-shaped notch.

[0032] The sliding block is composed of the mounting portion and the moving portion. The width of the moving portion is greater than the width of the mounting portion. The part of the moving portion greater than the mounting portion cooperates with the support side plate to assist the movement of the mounting portion and limit the position of the moving portion so that it only slides in the sliding groove. The end of the moving portion in contact with the pushing column is arranged as an arc-shaped notch, which facilitates the contact between the moving portion and the pushing column and makes the movement of the moving portion more smooth.

[0033] Further, the insertion rod is provided with a limiting ring, and the insertion rod is further provided with a third elastic component, which is a compression spring, the third elastic component is sleeved on the insertion rod, one end of the third elastic component is in contact with the limiting ring, and the other end is in contact with the positioning frame.

[0034] The limiting ring can be used to limit the position of the third elastic component, and the third elastic component also plays a supporting role. By installing the third elastic component, the position of the insertion rod can be limited, so that the insertion rod is prevented from being always in the ejection state due to the influence of the second elastic component. In addition, the third elastic component also plays a resetting role of the insertion rod, and is used for assisting the resetting of the insertion rod, so that the efficiency is improved.

[0035] Further, the end of the rotating column away from the pushing column is provided with a locking handle, and the mounting protrusion is further provided with a sealing cover, and the locking handle is located in the sealing cover.

[0036] In use, when the cover plate needs to be opened from the supporting plate, only the sealing cover needs to be opened, and then the locking handle is rotated, so that the second connecting mechanism is in an open state, and the cover plate can be opened. When the cover plate needs to be closed with the supporting plate, only the locking handle needs to be rotated in the opposite direction, so that the second connecting mechanism is in a closed state, so that the cover plate is closed, thereby playing a fixing role, preventing the cover plate from being automatically opened due to external factors, thereby improving the fixing effect of the drying cylinder body. At the same time, the handle can facilitate the user to operate, so that the process of opening and closing the cover plate is fast and convenient. The sealing cover can protect the locking handle and has the effects of dustproof and anti-misoperation.

[0037] The beneficial effects of the present application are:

[0038] 1. By providing the supporting device, the base can be fixed, thereby further fixing the drying cylinder body, effectively preventing the drying cylinder body from loosening or falling off when subjected to jolting. After the drying cylinder body, the base and the supporting plate are installed, the cover plate can be used for fixation, and the first connecting mechanism and the second connecting mechanism are used for further reinforcement, thereby effectively ensuring the installation stability of the drying cylinder body and preventing it from falling off.

[0039] 2. During the installation of the drying cylinder body, the drying cylinder body is inserted into the base. During the cooperation of the sliding member and the sliding groove, the bottom of the sliding member extrudes the protrusion, so that the outwardly protruding part of the protrusion is extruded and retracted into the cavity. When the sliding member continues to move downward, the clamping groove is in contact with the protrusion. At this time, the protrusion is extruded outwardly by the influence of the first elastic component and is matched with the clamping groove, so as to fix the sliding member in the sliding groove, thereby fixing the drying cylinder body on the base and the supporting plate, and effectively fixing the drying cylinder body.

[0040] 3、The second connecting mechanism can further improve the fixing effect of the drying cylinder body. When fixing, the first connecting mechanism needs to be installed first, and then the second connecting mechanism is installed. When installing the second connecting mechanism, since the second connecting mechanism is provided with two, and the two connecting mechanisms are symmetrically arranged on the support plate, the sliding member is fixed in the sliding groove by the cover plate, the top of the sliding member is blocked, and the cover plate and the support plate are fixed together, thereby further fixing the drying cylinder body, effectively preventing the drying cylinder body from loosening when being vibrated, and effectively fixing and installing.
