DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] For reference Figure 1-7 The utility model is described as follows:

[0030] Embodiment 1: A structurally stable electric push rod comprises a housing 1, a housing 2, and a base 3. One end of the housing 1 and the housing 2 is connected to the base 3. The housing 1 and the housing 2 are both cylindrical housing structures that are opened toward the base 3. The housing 1 and the base 3 are integrally formed. The inner cavity of the housing 1 is connected to the inner cavity of the base 3. The base 3 is also a housing structure that is opened on one side. The opening direction of the base 3 is the same as that of the housing 1. A threaded hole 2 is provided on the end surface of one end of the housing 2, and a connecting hole 2 13 corresponding to the threaded hole 12 is provided on the base 3. Screws are connected in the threaded hole 12 and the connecting hole 2 13 to fix the housing 2 and the base 3.

[0031] It also includes a connecting piece 4, the other ends of the shell 1 and the shell 2 2 are connected through the connecting piece 4, the connecting piece 4 is a plate-like structure, the connecting piece 4 is fixedly connected to the other end of the shell 1, the other end of the shell 1 is provided with a threaded hole 7, the connecting piece 4 is provided with a connecting hole 8 corresponding to the threaded hole 7, the connecting hole 8 and the threaded hole 7 are connected with fixing screws, the connecting piece 4 is provided with a positioning hole 9, the other end of the shell 1 is provided with a positioning protrusion 10 connected with the positioning hole 9; the shell 2 2 is plugged into the connecting piece 4.
