[0028] Reference Figure 1-4 The utility model provides a new type of tensioning bracket, including:

[0029] Main unit 100 includes a support body 101. A generator 106 is disposed on the upper side of support body 101. A first fixing slot 102 and a first connecting slot 103 are fixedly connected to the upper surface of support body 101. A second fixing slot 104 and a third fixing slot 105 are fixedly connected to one side surface of support body 101. First fixing slot 102, second fixing slot 104, and third fixing slot 105 are used to mount and secure support body 101. Connecting slot 103 is used to connect generator 106.

[0030] The tensioning unit 200 includes a fixed ring 201 fixedly connected to the bracket body 101, and a rotating ring 202 is rotatably connected to one side of the fixed ring 201, a sliding rod 203 is fixedly connected to the upper surface of the rotating ring 202, and a sliding sleeve 204 is slidably connected to the surface of the sliding rod 203, and the sliding sleeve 204 has the function of connecting to the generator 106. Limiting components 211 are provided on the upper and lower sides of the sliding sleeve 204. The interior of the fixed ring 201 is rotatably connected to a rotating shaft 205, and the surface of the rotating shaft 205 is movably connected to the rotating ring 202. The side of the rotating ring 202 facing away from the fixed ring 201 is detachably connected to a fixed block 206, and a locking component 208 is provided at one end of the fixed block 206.

[0031] Among them, the other end of the rotating shaft 205 is fixedly connected to the fixed block 206, and the fixed block 206 is fixedly connected to two groups of insertion rods 207 on one side of the rotating shaft 205. The surfaces of the two groups of insertion rods 207 are movably connected to the rotating ring 202. Through the movable connection between the insertion rods 207 and the rotating ring 202, not only can the rotating shaft 205 control the rotation of the rotating ring 202.

[0032] Furthermore, the locking assembly 208 includes a threaded rod 208a fixedly connected to the rotating shaft 205, and the surface of the threaded rod 208a is threadedly connected to a threaded barrel 208b, and the outer surface of the threaded barrel 208b is fixedly connected to multiple sets of toggle rods, and one side of the threaded barrel 208b is tightly fitted with the fixed ring 201. Threaded rotation of the threaded barrel 208b can make the threaded barrel 208b fit tightly with the fixed ring 201, thereby locking the fixed block 206, the rotating ring 202 and the fixed ring 201, so that the rotating ring 202 will not rotate on one side of the fixed ring 201.

[0033] Furthermore, both sets of limiting assemblies 211 include a limiting ring 211a that is slidably connected to the sliding rod 203, and one side of the limiting ring 211a is threadedly connected to a bolt 211b. By threading the bolt 211b, one end of the bolt 211b can be tightly fitted with the sliding rod 203, so that the limiting ring 211a and the sliding rod 203 are locked, thereby limiting the sliding sleeve 204.

[0034] Furthermore, a limiting groove 209 is provided on the surface of the slide rod 203, and a slider 210 is slidably connected inside the limiting groove 209. The slider 210 is fixedly connected to the sleeve 204 so that the sleeve 204 does not rotate when sliding on the surface of the slide rod 203, thereby facilitating the connection between the sleeve 204 and the generator 106.

[0035] Furthermore, a rubber ring 208c is fixedly connected to the side of the threaded barrel 208b facing away from the fixing ring 201, and the rubber ring 208c is rotatably connected to the threaded rod 208a. When locked, it can prevent oil and dirt from mixing between the threaded barrel 208b and the threaded rod 208a, and can clean the surface of the threaded rod 208a during rotation.

[0036] During use, the sleeve 204 is pushed to slide on the surface of the slide rod 203, and the generator 106 is connected to the connecting groove 103 and the sleeve 204. Then the slide rod 203 is rotated, and the rotating ring 202 fixedly connected to the slide rod 203 drives the rotating shaft 205 to rotate inside the fixed ring 201 through the insert rod 207. After the generator 106 reaches the specified position and is loaded with the belt and tightened, the threaded cylinder 208b is rotated, and the threaded cylinder 208b threadedly rotated with the threaded rod 208a will move toward the fixed ring 201, and the threaded cylinder 208b is tightly fitted with the fixed ring 201, thereby locking the rotating shaft 205 and the rotating ring 202, and at the same time locking the position of the slide rod 203 fixedly connected to the rotating ring 202. Finally, the bolt 211b is rotated, and the bolt 211b threadedly connected with the limiting ring 211a is tightly fitted with the slide rod 203, thereby limiting the sleeve 204.
