[0025] As shown, Figures 1 to 5 Water outlet pipe assembly 2 includes fixed sleeve 201, inner cover 202 and sealing sleeve 203, the inside top end of fixed sleeve 201 is provided with inner cover 202, and the top middle of fixed sleeve 201 is vertically provided with sealing sleeve 203, water outlet pipe assembly 2 further includes external pipe 204, internal pipe 205 and sealing ring 206, one side of fixed sleeve 201 is horizontally connected with external pipe 204, the inside of external pipe 204 is provided with internal pipe 205, and the inside of one end of external pipe 204 away from fixed sleeve 201 is installed with sealing ring 206, fixed sleeve 201, external pipe 204 and internal pipe 205 are all provided as one body structure, and fixed sleeve 201 is connected with main cylinder 1 by glue, water pump piston 4 includes piston pull rod 401, limiting sleeve 402, piston main body 403 and fixed joint 404, the lower end surface of piston pull rod 401 is provided with limiting sleeve 402, the bottom end of piston pull rod 401 is installed with piston main body 403, and fixed joint 404 is connected between piston main body 403 and piston pull rod 401, fixed joint 404 is connected with piston pull rod 401 and piston main body 403 by glue, and the top surface of piston main body 403 is provided with soft rubber plate, in addition, by being provided with external pipe 204 and internal pipe 205 on one side of fixed sleeve 201, sealing ring 206 is installed on the inner wall of one opening of external pipe 204, so that the whole water outlet pipe assembly 2 can have enough stability and structural sealing property when being connected and combined with external pipeline.

[0026] In summary, asFigures 1 to 4 As shown, the repeatedly detachable hand-held water pump, in use, first can use the water outlet pipe assembly 2 installed on the upper end of the main cylinder 1, through the outer connecting pipe 204 with the sealing ring 206 installed on the inner wall of one end, cooperate with the inner connecting pipe 205, so as to be mutually connected with the external drainage pipeline, then infiltrate into the water in the pit to the water inlet assembly 3 at the lower end of the main cylinder 1, then hold the handle 5 installed at the top end of the water pumping piston 4, pull the whole water pumping piston 4 along the inside of the main cylinder 1.

[0027] In this process, with the structure of the piston pull rod 401, the piston body 403 fixed at the bottom end by the fixed joint 404 will translate along the inner wall of the main cylinder 1, so as to generate negative pressure suction force, and the external water will quickly enter the inside of the main cylinder 1 under the action of the force, and the limiting sleeve 402 plays a limiting role in this process, avoiding the situation that the soft rubber plate set on the top surface of the piston body 403 exceeds the position of the fixed sleeve 201 when the handle 5 is pulled to the bottom, resulting in the failure to normally suck water, and the soft rubber water baffle 302 is made of soft PVC material, which will be deformed due to the action force of negative pressure adsorption when pumping water, so as to facilitate the external water flow to enter from the opening of the bottom valve 301.

[0028] Then, when the water pumping piston 4 is pulled to the position of the water outlet pipe assembly 2, the water flow will flow into the inner connecting pipe 205 from the inner opening of the fixed sleeve 201, and then flow into the external pipeline connected therewith, and then push the whole water pumping piston 4 in the main cylinder 1 to reset the structure, and then repeat the above operation to manually pump out the water in the pit gradually until the end.
