Compared with the existing mechanical wrench, the automatic socket wrench has the characteristics of high construction efficiency, good finished product quality, simple operation and low requirement on the professional degree of workers. The protective effect on the finished product of the operation surface is good, the working mode is changed, and the requirements on occupational health are met. It has the following advantages:

1. the construction efficiency is high: the existing construction mode is that a worker manually twists sleeves by using a wrench, each sleeve consumes long time, and the body loss is large in long-term stooping construction. Compared with the existing manual screwing sleeve, the automatic screwing sleeve has the characteristics of high speed, and the workload of one worker can reach that of three workers.

2. The construction quality is good: the construction quality of the existing manual screwing sleeve construction mode cannot be guaranteed, and the construction quality at the later stage is reduced and the buckle is missed frequently due to manual physical problems. The automatic socket wrench is used for twisting, so that the construction quality is greatly improved.

3. The operation is simple: at present, the sleeve is twisted manually and certain professional skill is needed, the operation is generally performed by a steel bar worker, the machine is compared with the existing construction mode, the wrench and the sleeve only need to be engaged, the switch 23 is opened, the operation is simple, and the adaptability is wide.

4. Is beneficial to the health of workers: the existing mode is that a manual wrench is used for screwing a sleeve, and because an operation surface is low, workers adopt squatting postures or half-squatting construction for a long time in work, and the knee and waist are seriously abraded. Meanwhile, in the process of screwing the sleeve, the wrench is rotated only by arm force of a worker, and the shoulder joint of the worker is seriously influenced by long-time repetition of the work. By applying the automatic socket wrench, workers are in standing postures during construction, and only the automatic socket wrench needs to be operated in a standing mode to complete corresponding work, so that the automatic socket wrench is beneficial to body health and reduces occupational disease occurrence probability.

It is obvious that the above embodiments of the present invention are only examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. And are neither required nor exhaustive of all embodiments. Any modification, equivalent replacement, and improvement made within the spirit and principle of the present invention should be included in the protection scope of the claims of the present invention.
