Summary of the invention
Technical problem to be solved in the utility model provides the specific purpose tool of a kind of slit depths nut and pad dismounting, utilizes the convenient dismounting of implementing small space inner nut and pad of this instrument, and the labour intensity that it effectively reduces dismounting has improved dismounting efficient.
For solving the problems of the technologies described above, the specific purpose tool of the utility model slit depths nut and pad dismounting comprises cylindrical body, sleeve, bearing pin, guide, spring and caging bolt, described cylindrical body one end is provided with circular counter bore, its other end is provided with square counterbore, end section is square before the described cylindrical body circular counter bore, the vertical tube wall of circular counter bore end of described cylindrical body is provided with screw, described caging bolt is twisted in the screw of described cylindrical body, described spring is positioned at the circular counter bore of described cylindrical body, described bearing pin surface is provided with chute vertically, a circular counter bore and an end that described bearing pin is positioned at described cylindrical body are butted on described spring, described caging bolt tail end is positioned at the chute of described bearing pin, the described bearing pin other end is provided with external screw thread, described guide is cylindrical and an end is provided with screw, the screw of described guide is screwed into the external screw thread of the described bearing pin other end, described sleeve one end is provided with square counterbore, its other end is provided with the hexagonal counterbore, the square counterbore of described sleeve and hexagonal counterbore connect, the square counterbore of described sleeve is inserted in described cylindrical body circular counter bore front end, and described guide is positioned at the square counterbore and the hexagonal counterbore of described sleeve.
The rotation of this instrument during for ease of the turn nut, this instrument also comprises one handle, described handle is located at the square counterbore end of described cylindrical body.
Because the specific purpose tool of the utility model slit depths nut and pad dismounting has adopted technique scheme, promptly make an end and be provided with circular counter bore, the other end is provided with the cylindrical body of square counterbore, end section is square before the circular counter bore of cylindrical body, have screw on the tube wall of circular counter bore, caging bolt is twisted in this screw, spring and bearing pin are positioned at the circular counter bore of cylindrical body successively, the bearing pin surface is provided with chute vertically, the tail end of caging bolt is positioned at this chute, the bearing pin head end is provided with external screw thread, guide is cylindrical, the one end is provided with screw and twists on the external screw thread of bearing pin head end, sleeve one end is square counterbore, the other end is the hexagonal counterbore and connects that its square counterbore was placed on the square-section of cylindrical body circular counter bore end after sleeve passed guide; The convenient dismounting of implementing small space inner nut and pad of this instrument of utilization, the labour intensity that it effectively reduces dismounting has improved dismounting efficient.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and embodiments:
Fig. 1 is the structural representation of the specific purpose tool of the utility model slit depths nut and pad dismounting.
The specific embodiment
As shown in Figure 1, the specific purpose tool of the utility model slit depths nut and pad dismounting comprises cylindrical body 8, sleeve 1, bearing pin 5, guide 2, spring 7 and caging bolt 6, described cylindrical body 8 one ends are provided with circular counter bore 81, its other end is provided with square counterbore 9, front end 82 cross sections of the circular counter bore 81 of described cylindrical body 8 are square, the vertical tube wall of circular counter bore 81 ends of described cylindrical body 8 is provided with screw, described caging bolt 6 is twisted in the screw of described cylindrical body 8, described spring 7 is positioned at the circular counter bore 81 of described cylindrical body 8, described bearing pin 5 surfaces are provided with chute 4 vertically, a circular counter bore 81 and an end that described bearing pin 5 is positioned at described cylindrical body 8 are butted on described spring 7, described caging bolt 6 tail ends are positioned at the chute 4 of described bearing pin 5, described bearing pin 5 other ends are provided with external screw thread 3, described guide 2 is cylindrical and an end is provided with screw 21, the screw 21 of described guide 2 is screwed into the external screw thread 3 of described bearing pin 5 other ends, described sleeve 1 one ends are provided with square counterbore 12, its other end is provided with hexagonal counterbore 11, the square counterbore 12 of described sleeve 1 and hexagonal counterbore 11 connect, the square counterbore 12 of described sleeve 1 is inserted in the front end 82 of described cylindrical body 8 circular counter bore 81, and described guide 2 is positioned at the square counterbore 12 and the hexagonal counterbore 11 of described sleeve 1.
