[0033] In this embodiment, the base 1 is in a cuboid shape, and the top surface of the base 1 is the fixing surface 101. The base 1 is cut from a metal plate, with a simple structure and convenient processing.

[0034] In addition, the cross-section of the mounting mechanism 2 is in a "C" shape, the base 1 is connected to the open end of the mounting mechanism 2, and the horizontally arranged part at the top of the mounting mechanism 2 is the mounting plate 201.

[0038] Preferably, the locking mechanism includes a first thread on the inner wall of the first mounting hole and a second thread on the side wall of the pressing rod 302, the first thread and the second thread are matched, and the first thread is engaged with the second thread. The cooperation of the first thread and the second thread not only facilitates the adjustment of the pressing and fixation of the to-be-fixed assembly by the pressing rod 302, but also can limit the pressing rod 302 in the vertical direction. Of course, the locking mechanism can also be a hydraulic locking sleeve or other structure that can lock and fix the pressing rod 302.

The setting of the pressing plate 304 can disperse the pressure and protect the assembly. At the same time, the threaded connection between the threaded cylinder 305 and the pressing rod 302 can make the pressure more uniform and prevent local damage. Of course, the shape of the pressing plate 304 is not limited to circular, but also other applicable shapes, and at the same time, the size of the pressing plate 304 is not limited to one kind, but can contain a variety of gradually changing sizes, when fixing different models and different sizes of the assembly to be fixed, the protector with a more applicable shape or size of the pressing plate can be selected to fix the assembly to be fixed more accurately.

[0041] Finally, the pitch of the thread on the inner wall of the threaded cylinder 305 is smaller than the pitch of the first thread. So that when rotating a circle, the distance of the upward and downward movement of the threaded cylinder 305 is smaller than the distance of the upward and downward movement of the pressing rod 302, and the fine adjustment of the pressure of the assembly to be fixed by the pressing mechanism 3 can be realized.

[0042] The above is only a preferred embodiment of the utility model, and is not used to limit the utility model, any modification, equivalent replacement and improvement within the spirit and principle of the utility model should be included in the protection scope of the utility model.
