[0027] like Figure 1-Figure 3 As shown, an adjustable pit distance shifter of an embodiment of the utility model comprises: a first pipe 1, a second pipe 2 and a connecting piece 3; the first pipe 1 comprises a first connecting portion 11 and a first adjusting portion 12 extending along a first direction X, one end of the first connecting portion 11 is used to connect to the sewage outlet of the toilet, the first adjusting portion 12 is connected to the other end of the first connecting portion 11 at one end in the first direction X, the first adjusting portion 12 can be inserted into one end of the second pipe 2 at the other end in the first direction X, and the other end of the second pipe 2 is used to connect to the lower sewage outlet; the outer peripheral side surface of the first adjusting portion 12 has a plurality of cutting grooves 121 arranged at intervals along the first direction X, the plurality of cutting grooves 121 divide the first adjusting portion 12 into a plurality of partitions 122, and the cutting grooves 121 are used for cutting to adjust the length of the first adjusting portion 12 in the first direction X; the connecting piece 3 is detachably arranged on the outer peripheral side surface of the first adjusting portion 12, and can be arranged on any partition 122, and the first adjusting portion 12 can be connected to one end of the second pipe 2 through the connecting piece 3.

[0028] Based on the above scheme, the present application sets a plurality of cutting grooves 121 for cutting on the outer peripheral side of the first adjusting part 12, so that the length of the first adjusting part 12 in the first direction X can be adjusted by cutting the cutting grooves 121 on the first adjusting part 12, so that the length of the pit distance shifter can be adjusted according to the relative position of the sewage outlet of the toilet and the lower sewage outlet, so as to realize the connection between the sewage outlet of the toilet and the lower sewage outlet, and in the process of installation of the present application, since the length of the first adjusting part 12 in the first direction X is adjusted by cutting, there is no need to consider the sealing problem caused by the splicing of multiple sections of pipes, and the operation is very convenient, and the installation can be completed by connecting the cut first adjusting part 12 to the second pipe 2 through the connecting piece 3. In addition, since the connecting piece 3 is detachably installed on the first adjusting part 12, the connecting piece 3 can be removed after cutting the cutting groove 121 and reinstalled on the remaining partitions 122 for use, so as to achieve the technical effect of saving materials.

[0029] like Figure 3 As shown, in some embodiments, in order to facilitate cutting, the cutting groove 121 extends along the circumference of the first adjustment portion 12 .

[0030] like Figure 1-Figure 4 As shown, in order to enable the application to realize the function of continuously adjusting the length of the pit distance shifter within a certain length range, the second pipe 2 includes a second connecting portion 21 and a second adjusting portion 22 extending along the first direction X, the first adjusting portion 12 has a first end 123 and a second end 124 at two ends in the first direction X, and the second adjusting portion 22 has a third end 221 and a fourth end 222 at two ends in the first direction X, the first end 123 is connected to the first connecting portion 11, the second end 124 can be inserted into the third end 221, and the fourth end 222 is connected to one end of the second connecting part 21, and the other end of the second connecting part 21 is used to connect to the lower sewage pipe outlet; in the first direction X, the distance from the side of the connecting piece 3 away from the second pipe 2 to the second end 124 is L1, and the distance from the side of the connecting piece 3 away from the second pipe 2 to the fourth end 222 is L2; ​​among the multiple partitions 122, the partition 122 connected to the first connecting part 11 is the connecting section 125, and the remaining partitions 122 are cutting sections 126. In the first direction X, the length of the longest cutting section 126 is L3, L2-L1≥L3.

[0031] Since the connecting member 3 of the present application can be detachably installed on the first adjusting portion 12 between any two adjacent cutting grooves 121, the connecting member 3 can adjust the installation position according to the relative position of the sewage outlet of the toilet and the lower sewage outlet. On this basis, multiple cutting grooves 121 divide the first adjusting portion 12 into a connecting segment 125 and multiple cutting segments 126. After each cutting segment 126 is cut, the length range of the pit distance shifter can be adjusted to L2-L1 by adjusting the installation position of the connecting member 3 and the length of the first adjusting portion 12 inserted into the second pipe 2. When the length L3 of the longest cutting segment 126 is made ≤L2-L1, the length range of the pit distance shifter that can be adjusted by cutting two adjacent cutting grooves 121 will appear continuous or overlapping, thereby ensuring that the present application can achieve the function of continuous adjustment of the length of the pit distance shifter within a certain length range.

[0032] like Figure 3 As shown, for ease of use, a plurality of cutting grooves 121 are evenly spaced along the first direction X, and in combination with the present application, the length of the pit distance shifter can be continuously adjusted within a certain length range.
