[0019] Further improvements include the integration of several stop pin assemblies 4 at equal intervals onto the cement head 2, with a handwheel 6 mounted on one end of each stop pin assembly 4, and a connecting harness 3 integrated into the remote control rotating component 5.

[0020] Further improvements include the integration of several indicator lights and a display panel on one side of the controller 1, and the provision of several fixing threaded holes 14 on the top and bottom of the connecting outer frame 8. Bolts are installed on both the fixing threaded holes 14 and the fastening through holes 7. The bolts located on the fixing threaded holes 14 are threadedly connected to the controller 1, and the bolts located on the fastening through holes 7 are threadedly connected to the threaded holes 17.

[0021] Further improved, one end of the connecting post 12 is attached to the outer edge of the movable compartment 16, and the remaining part is spaced apart from the movable compartment 16. Specifically, the connecting post 12 is used to ensure the connection between the connecting outer frame 8 and the fixed side plate 9, and to realize the movement of the connecting outer frame 8, so as to facilitate the connection and fixation of the connecting wire harness 3. The connecting outer frame 8 has a through hole on the side facing the fixed side plate 9 that communicates with the movable compartment 16 and the movable compartment 2 18. Specifically, the through hole is used for the movable connection between the connecting post 12 and the connecting fixed plate 11. The size of the through hole on the connecting post 12 is the same as the size of the smaller part of the connecting post 12.

[0022] Further improvements include a fixed side plate 9 located on the cement head 2 and having several mounting threaded grooves 10, a connecting fixed plate 11 having a cuboid structure, and a sealing gasket on the side of the connecting outer frame 8 that contacts the fixed side plate 9.

[0023] Further improvements include an open structure at both ends of the connecting outer frame 8. Specifically, ventilation holes are provided at the bottom of the connecting outer frame 8, and a dustproof mesh is integrated therein. Several cable slots 15 are evenly provided on the bottom of the side of the connecting outer frame 8 facing the fixed side plate 9. The cable slots 15 have an arc-shaped structure. Several connection ports are integrated on the controller 1. Specifically, the ports of the connecting harness 3 are plugged into the connection ports, and part of the connecting harness 3 is fixed on the cable slots 15.

[0024] In use: First, the fixed side plate 9 and the connecting outer frame 8 are connected to the mounting clamp and other connecting structures through the mounting threaded groove 10, and then fixedly installed on the cement head 2 through the connecting structure. Then, part of the controller is placed into the connecting outer frame 8, and the controller 1 is fixedly installed by bolting the threaded hole 14. Next, the bolts on the fastening through hole 7 are removed, and the connecting outer frame 8 is moved away from the fixed side plate 9 to increase the distance between the connecting outer frame 8 and the fixed side plate 9. At this time, the connecting wire harness 3 can be passed through the bottom of the connecting outer frame 8 and connected to the connection port of the controller 1. After completion, the connecting wire harness 3 is placed in the cable slot 15 in sequence, and the connecting outer frame 8 is moved back. The bolts are then passed through the fastening through hole 7 and connected to the threaded hole 17.

[0025] The controller-1, cement head-2, connecting wire harness-3, stop pin assembly-4, remote control rotating component-5, handwheel-disc-6, fastening through hole-7, connecting outer frame-8, fixing side plate-9, mounting threaded groove-10, connecting fixing plate-11, connecting post-12, fixing threaded hole-14, cable slot-15, movable compartment one-16, threaded hole-17, movable compartment two-18 of this utility model are all general standard parts or parts known to those skilled in the art. Their structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods. The problem solved by this utility model is that controllers used for remote control are generally only fixed to the cement head by structures such as clamps, and their interfaces for connecting switches and other structures, as well as the connecting wire ends, are exposed externally. During use, dust and other impurities can adhere to the cable connections, affecting the stability of the controller's operation. This invention addresses this issue by combining the aforementioned components: the connecting outer frame, the fixed side plate, and the connecting fixing plate. These components conveniently protect the connecting wire harness and the controller's connection port. During installation, the connecting outer frame is moved to increase the distance between it and the fixed side plate, facilitating the insertion of the connecting wire harness posts one by one into the controller's connection port. After connection, one side of the connecting outer frame is attached to the fixed side plate, and bolts are threaded through the fastening through-holes and threaded holes to fix the connecting outer frame, thus protecting the ends of the connecting wire harness and preventing the accumulation of dust and impurities, ensuring the controller's operational stability.

[0026] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects. The scope of this utility model is defined by the appended claims rather than the foregoing description, and thus all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this utility model. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0027] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
