These devices enable precise alignment during assembly, rapid and accurate movement and handling, intelligent sensing of operator activity, overload protection, power failure protection, and anti-rebound technology. Currently, traditional intelligent lifting devices consist of components such as servo motors, precision planetary gear reducers, servo drivers, main control modules, control handles, rollers and frames, wire ropes, and hooks. The lifting and lowering of the hook is typically controlled by a control handle.

[0003] For example, the China Patent Network discloses a handle control structure for an intelligent lifting device [Authorization Announcement No.: CN214879554U], which includes an annular spring groove on the inner circumference of the handle, a support seat screwed onto the connecting rod, the support seat being located in the spring groove, pressure sensors being provided on both the upper and lower surfaces of the support seat, and springs sleeved on the connecting rod and located in the spring groove on both the upper and lower surfaces of the support seat, with one end of the spring abutting against the pressure sensor and the other end abutting against the bottom or top surface of the spring groove.

[0004] The above-mentioned handle control structure has the following defects during use: pressure sensors are set on both the upper and lower surfaces of the support base and are located in the spring groove. In order for the pressure sensors to accurately sense the pressure, the connecting rod needs to maintain absolute stability in the axial direction. This connecting rod is only suitable for the structure of electric slip rings and has a single function. Summary of the Invention

[0005] To address the shortcomings of existing technologies, the purpose of this invention is to provide a handle control device for a hoist. The technical problem this invention aims to solve is: how to make the handle control device applicable to more scenarios and improve convenience.

[0007] Furthermore, the connecting rod has a fixing plate protruding outward from one end near the control housing. The fixing plate has a T-shaped hole, and the control housing has a mounting through hole opposite to the T-shaped hole. The pressure sensor is located in the mounting through hole, and the lower part of the pressure sensor passes through the mounting through hole and abuts against the T-shaped hole before being fixedly connected to the handle sleeve. A pressure sleeve is fixedly installed on the upper part of the mounting through hole, and the pressure sleeve abuts against and is fixed to the pressure sensor.

[0008] Furthermore, an annular groove is provided on the inner circumferential surface of the handle sleeve, and one end of the spring abuts against the side wall of the annular groove and the other end abuts against the locking sleeve.

[0009] Furthermore, the upper part of the pneumatic-electric shaft is located inside the pneumatic-electric base, and a thrust bearing, a washer, and a radial bearing are arranged sequentially from bottom to top inside the pneumatic-electric base. The pneumatic-electric shaft abuts against the radial bearing. A weighing sensor is also installed inside the control housing. The lower part of the pneumatic-electric shaft passes downward through the radial bearing, the washer, the thrust bearing, and the control housing and is fixedly connected to the weighing sensor. The inner side of the control housing abuts against the upper end face of the weighing sensor.

[0010] Furthermore, an electric connector is fixedly connected to the upper end of the electric base, an upper conversion plate is fixedly connected to the lower end face of the electric connector, and a lower conversion plate is fixedly connected to the upper end face of the electric shaft.
