Adjustment grooves 108 are provided at both ends of the positioning bracket 103, and both inner sides of the adjustment grooves 108 are provided with T-shaped grooves 109 and two sliding grooves 110. The middle part of the positioning bracket 103 is provided with a threaded groove 111. The support screw 101 is threadedly connected to the positioning bracket 103 and is located in the threaded groove 111. The adjustment block 104 is slidably connected to the positioning bracket 103 and is located in the corresponding adjusting groove 108. The sliding block 106 is located in the sliding groove 110, and the T-shaped threaded sleeve 105 is located in the T-shaped groove 109. By The positioning bracket 103 is used for positioning, and the support screw 101 is used as a fulcrum; during the on-site operation, the two nuts 107 are screwed into the corresponding threaded parts of the lower rod-shaped structure of the positioning stud 102, and the screwing depth must be consistent to ensure that the threaded parts are screwed into the oil seal at a consistent depth; the positioning stud 102 is symmetrically screwed into the oil seal to be removed. If it is difficult to screw in, two holes can be drilled on the shaft cover with a pistol drill. The two holes are symmetrical with the shaft center. The positioning bracket 103 is pressed against the pump shaft for positioning, and the two positioning studs 102 are adjusted to a suitable spacing through the adjustment mechanism; then the nut 107 is screwed to drive the support screw 101 to rotate, and simultaneously drive the positioning bracket 103 to move upward. At this time, the positioning stud 102 will drive the oil seal to be removed together, thereby achieving the purpose of removing the oil seal.

[0026] Among them, a driven gear 115 is provided at one end of the bidirectional screw 112, and the two bidirectional screws 112 are respectively rotatably connected to the positioning bracket 103 through bearings, and are located in the T-shaped slot 109 and penetrate one end of the positioning bracket 103. The T-shaped threaded sleeve 105 is threadedly connected with the corresponding bidirectional screw 112 and sleeved on the bidirectional screw 112. The driven gear 115 is transmission-connected with the driving gear and is located on the outside of the driving gear and is also located in the installation box 114. The driving gear is connected to the installation box 114. The mounting box 114 is rotatably connected and is located in the mounting box 114.

The gear body 113 can be supported by the rotating shaft 116, thereby ensuring normal transmission between the gear body 113 and the driven gear 115.

[0028] Again, a knob 117 is provided at one end of the rotating shaft 116 , and a plurality of anti-skid protrusions 118 are provided on the outer side of the knob 117 . The rotating shaft 116 can be easily rotated by the knob 117 , and the anti-skid protrusions 118 can improve the gripping force of the knob 117 .

[0029] When the utility model is used to adjust the two positioning studs 102, the knob 117 is rotated to transmit the driving gear, and the two driven gears 115 are driven by the driving gear to rotate the bidirectional screw 112 in the T-slot 109, so that the T-shaped threaded sleeve 105 is threadedly connected with the bidirectional screw 112, and then the T-shaped threaded sleeve 105 on the two bidirectional screws 112 drives the two positioning studs 102 to move synchronously, thereby completing the adjustment.
