DETAILED DESCRIPTION

[0020] In order to more clearly illustrate the technical solution of the utility model, the utility model is further described below in conjunction with the accompanying drawings. Obviously, the accompanying drawings described below are only one embodiment of the utility model. For ordinary technicians in this field, without paying any creative work, other embodiments can be obtained based on this drawing and embodiment, which all belong to the protection scope of the utility model.

[0021] according to Figure 1-7As shown, a multi-directional tensioner comprises two tensioning sleeves 1, and the two tensioning sleeves 1 are respectively connected with two tensioning screws 2 with opposite thread directions, a fixed sleeve 3 is provided between the two tensioning sleeves 1, a movable sleeve 4 is rotatably mounted on the fixed sleeve 3, the movable sleeve 4 is connected with an adjusting screw 5, and the ends of the adjusting screw 5 and the tensioning sleeve 1 are provided with pull rings 6.

[0022] In the above specific implementation, a movable sleeve 4 is provided on the fixed cylinder 3, and the movable sleeve 4 can be rotated as needed, thereby increasing the applicability of the tensioner. The design of the tensioner can tighten objects in multiple directions at the same time, reducing the number of tensioners used and reducing the transportation cost of the enterprise.

[0023] The movable sleeve 4 includes a cylinder 41 and a fixed seat 42 arranged at the end of the cylinder 41. The fixed seat 42 is connected to the cylinder 41 through a thrust bearing 43. The fixed seat 42 is threadedly connected to the adjusting screw 5. The adjusting screw 5 can be extended and retracted by rotating the fixed seat 42, thereby achieving the tightening of the object.

[0024] The fixing seat 42 is provided with a fixing piece 44 , which is composed of two semicircular ring structures. One end of the fixing piece 44 is fixedly connected to the fixing seat 42 , and the other end is rotatably connected to the cylinder 41 . The fixing seat 42 is rotatably mounted on the cylinder 41 through the fixing piece 44 .
