In addition, the conical adjusting surface is arranged on the pressing rod, so that the central position of the pressed piece can be automatically adjusted when the pressing rod extrudes the pressed piece, and the pressed piece can be accurately assembled in place.
And the connecting piece and the driving piece are fixed in a clamping mode, so that the device is convenient to disassemble, assemble and maintain.
Moreover, the invention is provided with a return structure, thereby effectively saving time and labor.
Finally, the invention has simple structure, and can conveniently and accurately realize the compression of the compressed piece.
It is to be understood that the above-described embodiments are merely illustrative of some, but not restrictive, of the broad invention, and that the appended drawings illustrate preferred embodiments of the invention without limiting its scope. This invention may be embodied in many different forms and, on the contrary, these embodiments are provided so that this disclosure will be thorough and complete. Although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that various changes in the embodiments and modifications can be made, and equivalents may be substituted for elements thereof. All equivalent structures made by using the contents of the specification and the attached drawings of the invention can be directly or indirectly applied to other related technical fields, and are also within the protection scope of the patent of the invention.
