Fig. 2 is the sectional view in A-A directions in the utility model Fig. 1.
Fig. 3 is the sectional view in B-B directions in the utility model Fig. 2.
Specific embodiment
Specific embodiment of the present utility model is described in further detail below in conjunction with attached drawing.
Embodiment:
It being provided by Fig. 1 to Fig. 3, the utility model includes protection pipe 1, and the end of protection pipe 1 is equipped with annular fixed block 2, Multiple straight slots 3 are evenly equipped on the side of annular fixed block 2, U-shaped piece 4 are provided on annular fixed block 2, U-shaped piece 4 of right plate is slided Dynamic to be mounted in straight slot 3, U-shaped piece 4 end for stretching into annular 2 side of fixed block is stretched into protection pipe 1, on annular fixed block 2 in Each 3 left side of straight slot is provided with the inside blind hole 5 that is open, and is provided with tension spring 6 in blind hole 5, one end and the blind hole 5 of tension spring 6 are fixed Connection, the other end of tension spring 6 are fixedly connected with U-shaped piece 4, and the right side of annular fixed block 2 is slidably fitted with scratch diskette 7, scratch diskette 7 On be provided with threaded hole 8, it is replaceable in threaded hole 8 that line sending head 9 is installed.
In order to enable scratch diskette 7 can slide on annular fixed block 2, the right end of the annular fixed block 2 fixes peace Equipped with supporting rod 10,2 right side of annular fixed block is provided with scratch diskette 7, is provided with sliding slot 11 on scratch diskette 7, and supporting rod 10 can be It is slided in sliding slot 11.
In order to enable scratch diskette 7 can be fixedly connected with annular fixed block 2, the end thread installation of the supporting rod 10 There is nut 12, the diameter length of nut 12 is more than the width of sliding slot 11.
The line sending head 9 includes trapezoid block 13, and the outside of trapezoid block 13 can be threadedly coupled with threaded hole 8, trapezoid block 13 On be provided with line sending pipe 14, line sending pipe 14 runs through the left side and right side of trapezoid block 13, and protection is stretched into the end of line sending pipe 14 In pipe 1.
In order to enable U-shaped piece 4 can be more stable be fitted on the madial wall of protection pipe 1, described U-shaped piece 4 is stretched into ring Shape fixed block 2 and the side that is contacted with protection pipe are arcwall face.
