[0006] Preferably, the hexagonal nut is welded above the upper pressure plate.

[0007] Preferably, the first sleeve is welded below the upper pressure plate.

[0008] Preferably, a trapezoidal internal thread is provided inside the first sleeve, and the first sleeve can be rotatably engaged with the trapezoidal lead screw.

[0009] Preferably, the second sleeve is welded to the lower base.

[0010] Preferably, a trapezoidal internal thread is provided inside the second sleeve, and the second sleeve can be rotatably engaged with the trapezoidal lead screw.

[0011] Preferably, a center hole is opened on the lower base, and the trapezoidal lead screw passes through the center hole and is welded to the lower base.

[0012] Preferably, a plurality of bolt holes are provided at the bottom of the lower base, and the lower base is connected to a fixing device such as a foundation through the bolt holes.

[0013] Beneficial effects of the utility model:

[0014] The utility model discloses can realize the purpose of compressing the spring by rotating the hexagonal nut on the upper end of the threaded sleeve with a manual wrench. The device has the advantages of simple structure, convenient operation, detachability and adjustable compression distance. The overall size after compression is small, and it can be applied to occasions with small overall size requirements. It is convenient to store and transport and has high practical value.

[0018] In order to make the objectives, technical solutions and advantages of the present application more clearly understood, the present application is further described in detail below with reference to the accompanying drawings and examples.

[0019] The present application embodiment discloses a simple adjustable manual compression spring device, such as Figure 1 As shown, it includes an upper pressure plate 2, a through hole is opened in the middle of the upper pressure plate 2, a hexagonal nut 1 is arranged above the upper pressure plate 2, a hollow first sleeve 3 is arranged below the upper pressure plate 2, a trapezoidal screw 4 is connected below the first sleeve 3, and the lower end of the trapezoidal screw 4 passes through the hollow second sleeve 5 and is connected to the lower base 6.

[0020] In a specific embodiment, the hexagonal nut 1 is welded above the upper platen 2, and the first sleeve 3 is welded below the upper platen 2. The first sleeve 3 is provided with a trapezoidal internal thread inside, and the first sleeve 3 can be rotatably engaged with the trapezoidal lead screw 4. The second sleeve 5 is welded on the lower base 6. The second sleeve 5 is provided with a trapezoidal internal thread inside, and the second sleeve 5 can be rotatably engaged with the trapezoidal lead screw 4.

[0021] like Figure 3 As shown, a center hole is provided on the lower base 6, and the trapezoidal lead screw 4 passes through the center hole and is welded on the lower base 6. A plurality of bolt holes 7 are provided at the bottom of the lower base 6, and can be connected to a fixing device such as a foundation through the bolt holes 7.

[0022] When in use, first remove the first sleeve 3, then insert the cylindrical spring into the trapezoidal screw 4, and limit the lateral position of the spring by the second sleeve 5. Then install the first sleeve 3 on the trapezoidal screw 4, rotate the hexagonal nut 1 to make the first sleeve 3 mesh with the trapezoidal screw 4, so that the spring begins to compress, and adjust the compression distance by rotating the hexagonal nut 1.
