In the above process, the two sets of rings 210 are respectively sleeved on the outer walls of the right handle 109 and the left handle 110, and the motor 209 drives the gear set 208 to rotate, and the gear set 208 drives the spiral disk 207 to rotate, and the worm gear 206 brought by the spiral disk 207 rotates, so that the worm gear 206 pushes the helical teeth 205, thereby driving the two sets of pull rods 204 to slide, and the pull rods 204 drive the rings 210 so that the rings 210 pull the right handle 109 and the left handle 110 to flip.

[0042] Please refer to Figure 5 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 and Fig.10 One end of the gear set 208 is fixedly connected to a reciprocating screw rod 211, the end of the reciprocating screw rod 211 is rotatably connected to the inner wall of the rear warehouse 203, the inner wall of the rear warehouse 203 is slidably connected to a sleeve 212, the top of the sleeve 212 is threadedly connected to the outer wall of the reciprocating screw rod 211, the side wall of the sleeve 212 is fixedly connected to a hydraulic component 213, the inner wall of the rear warehouse 203 is fixedly connected to a silicone oil tank 214 located next to the hydraulic component 213, and the hydraulic component The member 213 includes a sleeve 2131, which is fixedly connected to the inner wall of the rear chamber 203, and the inner wall of the sleeve 2131 is slidably connected to a hydraulic piston 2132, and the side wall of the hydraulic piston 2132 is fixedly connected to a push rod 2133 extending to the outside of the sleeve 2131, and one end of the push rod 2133 located outside the sleeve 2131 is fixedly connected to the side wall of the sliding sleeve 212, and the side wall of the sleeve 2131 is connected to the silicone oil chamber 214 at one end. Inside, the sleeve 2131 is provided with a first one-way valve 2134 at the place where it is connected to the silicone oil tank 214, the side wall of the hydraulic piston 2132 is penetrated with two groups of through holes 2135, the side wall of the hydraulic piston 2132 is provided with two groups of second one-way valves 2136, the position of the second one-way valve 2136 is consistent with the through hole 2135, the top of the middle plate 202 is fixedly connected with the injection assembly 215, the injection assembly 215 includes a fixing seat 2151, the fixing seat 2151 is fixedly connected to the top of the middle plate 202, and the side wall of the fixed seat 2151 is rotatably connected with two groups of side nozzles 2152, and the two groups of side nozzles 2152 are connected to the end of the sleeve 2131 through a pipeline, and the inner wall of the fixed seat 2151 is slidably connected with two groups of friction blocks 2153, and the two groups of friction blocks 2153 are respectively attached to the side walls of a group of side nozzles 2152, and two groups of spring sheets 2154 are fixedly connected between the two groups of friction blocks 2153.

[0043] During the rotation of the gear set 208, the reciprocating screw 211 is driven to rotate, so that the reciprocating screw 211 drives the sleeve 212 to move back and forth, so that the sleeve 212 continuously pushes and pulls the push rod 2133. During the continuous pushing and pulling of the push rod 2133, the hydraulic piston 2132 is driven to slide back and forth on the inner wall of the sleeve 2131. When the hydraulic piston 2132 slides toward the connection between the sleeve 2131 and the pipeline, the silicone oil between the hydraulic piston 2132 and the pipeline is pushed to flow into the piston, so that the silicone oil is sprayed out through the side nozzle 2152. At this time, the second one-way valve 2136 is tightly connected to the side wall of the hydraulic piston 2132 under the action of pressure. The two hydraulic pistons 2132 and 2134 are in close contact with each other, and negative pressure is generated on the side of the piston away from the second one-way valve 2136, so that the silicone oil in the silicone oil tank 214 is sucked into the sleeve 2131. During the reverse sliding of the hydraulic piston 2132, the silicone oil flowing from the silicone oil tank 214 into the sleeve 2131 is compressed. At this time, the first one-way valve 2134 is tightly closed, and the second one-way valve 2136 is pushed open, so that the silicone oil flows to the other side of the hydraulic piston 2132. Every time the hydraulic piston 2132 slides back and forth on one side, the side nozzle 2152 completes a silicone oil injection, so that the silicone oil is continuously injected onto the piston body 4 and the installation tool body 1.

The sealing ring 3 is installed, so that the seal can be installed safely and effectively during the installation process without causing damage to the seal and the piston workpiece, thereby improving the installation efficiency and avoiding the risk of hand injury to the operator. The parts not involved in the device are the same as the prior art or can be implemented using the prior art.
