[0017] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0018] like Figures 1 to 4 As shown, this embodiment includes an integrated pump base 1, a pump housing 2, and a pump shaft 3. The bottom of the integrated pump base 1 is rectangular, and the four sides of the integrated pump base 1 are arc-shaped structures that taper inward. The connecting arm 11 is integrally injection molded from the arc-shaped structure that tapers inward from the integrated pump base 1 upward. A first connector 12 is formed at the end of the connecting arm 11. The integrated pump base 1 at the arc-shaped structure that tapers inward extends forward to form a second connector 13. The pump housing 2 is integrally installed on the front side of the integrated pump base 1. A first connecting seat 21 and a second connecting seat 22 are formed at the rear end of the pump housing 2. The first connecting seat 21 and the second connecting seat 22 are respectively attached to the first connecting head 12 and the second connecting head 13 and are fixedly connected by bolts.

[0019] To elaborate further, such as Figures 2 to 4 As shown, a first groove 121 is provided at the upper end of the first connector 12, and a second groove 131 is provided at the lower end of the second connector 13. A first protrusion 211 and a second protrusion 221 are formed at corresponding positions of the first connector 21 and the second connector 22. When the pump housing 2 and the integrated pump base 1 are connected, the first protrusion 211 and the first groove 121 fit together, and the second protrusion 221 and the second groove 131 fit together, which further achieves the effect of stabilization and fixation.

[0020] like Figures 1 to 4 As shown, a first bearing seat 14 is formed on the integrated pump base 1 at the lower end of the connecting arm 11. An upwardly extending tail arm 15 is formed at the rear end of the integrated pump base 1. A second bearing seat 16 is formed at the end of the tail arm 15. One end of the pump shaft 3 extends out from inside the pump housing 2 and passes through the first bearing seat 14 and the second bearing seat 16. Sealing bearing covers are fixedly sealed on both sides of the first bearing seat 14. A spherical cover 5 is fixedly connected to the outside of the second bearing seat 16. The other end of the pump shaft 3 is located inside the spherical cover 5. A pulley 4 is sleeved and connected to the outside of the pump shaft 3 located between the first bearing seat 14 and the second bearing seat 16. The pulley 4 can be connected to an external drive device to drive the pump shaft 3 and this embodiment to operate.

[0021] To elaborate further, such as Figures 1 to 4 As shown, the bottom of the integrated pump base 1 has a hollow structure, which reduces the overall weight of this embodiment. Fixing grooves 17 are provided on the four corners of the bottom of the integrated pump base 1. The fixing grooves 17 facilitate the fixed installation of this embodiment with other instruments.
