the clamping block (25) forms a sliding structure with the butt joint block (31) through the clamping groove (21), the sliding groove (22) and the sliding block (23), the clamping block (25) forms an elastic structure with the butt joint block (31) through the second spring (24), and the cross section of the front end of the clamping block (25) is in a right trapezoid shape;
the inner wall of the inclined groove (26) is matched with the outer wall of the front end of the clamping block (25), and the inclined groove (26) is communicated with the through hole (27);
the movable rod (28) forms an elastic structure with the fixed plate (35) through the third spring (29), the cross section of the fixed plate (35) is L-shaped, and the butt joint block (31) penetrates through the inside of the fixed plate (35);
the supporting seat (1) is spliced by an external bolt matched with a screw hole (5), so that a motor (2) and a threaded rod (3) are fixed, a first outer bushing (7) and a second outer bushing (9) are required to be lapped, an inner rod (17) and an inner groove (18) on the first outer bushing (7) are butted with a corresponding inner rod (17) and an inner groove (18) on the second outer bushing (9), at the moment, a butt-joint block (31) at the front end of an extension plate (19) is clamped into a lapping groove (20) in a fixing plate (35), as the front surface of a clamping block (25) is an inclined surface, the clamping block (25) is retracted into the clamping groove (21) under the extrusion action of the outer surface of a connecting handle (30) on the inclined surface of the clamping block (25), a second spring (24) is compressed, and the clamping block (25) is retracted towards the inside of the clamping groove (21), the sliding block (23) slides in the sliding groove (22), so that the clamping block (25) is completely retracted into the clamping groove (21), until the front end of the clamping block (25) moves to the inclined groove (26), the clamping block rebounds under the action of the elastic force of the second spring (24), so that the clamping block (25) is completely clamped into the fixing plate (35), at the moment, the fixing plate (35) and the extension plate (19) are mutually clamped, therefore, the first outer bushing (7) and the second outer bushing (9) are also mutually clamped, the integral installation work of the device is completed, when the spliced vertical pipe body (33) needs to be sprayed and maintained, the first outer bushing (7) and the second outer bushing (9) need to be placed on the front side and the rear side of the vertical pipe body (33) before the first outer bushing (7) and the second outer bushing (9) are spliced, and when the first outer bushing (7) and the second outer bushing (9) need to be contacted and clamped, by pressing down the connecting handle (30) to make the movable rod (28) slide in the through hole (27), the third spring (29) is compressed until the movable rod (28) presses the clamping block (25) to the inner part of the inclined groove (26), and then the first outer bushing (7) and the second outer bushing (9) can be disassembled according to the reverse steps during the installation;
when the surface of the vertical pipe body (33) is sprayed, the first lap plate (6) is in threaded connection with the threaded rod (3), the threaded rod (3) is driven to rotate through the motor (2), the first outer lining (7) and the second outer lining (9) which are spliced are lifted under the limiting effect of the limiting rod (4) and the second lap plate (8), so that the surface of the vertical pipe body (33) is fully sprayed, in order to adapt to vertical pipe bodies (33) of different sizes, the device supports the vertical pipe body (33) through a square rod (10) inside a communication groove (12) and a first spring (11), when the first outer lining (7) and the second outer lining (9) move up and down, the roller (15) rolls on the connecting block (13) through the connecting shaft (14), and a rubber sleeve (16) on the outer side of the roller (15) protects the surface of the vertical pipe body (33), the whole spraying work is completed through the spray pipe (32) and the spray hole (34).
