The opposite ends of each group of springs 109 are respectively installed on the opposite sides of each group of rectangular blocks 110. Each three-headed rope 108 is respectively inside each three-way pipe 107, and the three ends of each three-headed rope 108 respectively extend out from the three ports of each three-way pipe 107. Two ends of each three-headed rope 108 are respectively movably sleeved inside each group of springs 109. A protection mechanism 2 is arranged on the quick-change mechanism 1. The protection mechanism 2 includes two perforated plates 201 and two protective shells 202. Flat plates 203 are fixed on the tops and bottoms of the two protective shells 202. Two symmetrically opposite hand-tightening bolts 204 are threadedly penetrated through the front surfaces of each flat plate 203. Rubber strips 205 are adhesively connected to both sides of each protective shell 202. The two perforated plates 201 are respectively fixedly sleeved on the outer surfaces of the fixed ends of the two electric push rods 103.

[0024] The achieved effect is that when the auxiliary tool needs to be installed on the skid steer loader, first install the mounting plate 101 at a suitable position on the skid steer loader. Then connect both electric push rods 103 to the controller (PLC controller) on the skid steer loader. Next, use the controller to simultaneously start both electric push rods 103. At this time, both started electric push rods 103 will drive the other ends of the corresponding three-headed ropes 108 to move under the cooperation of the corresponding round plates 104. At this time, the other ends of both moving three-headed ropes 108 will drive the corresponding set of rectangular blocks 110 to move towards each other inside the corresponding connecting blocks 105 under the cooperation of the corresponding connecting blocks 105, the corresponding three-way pipes 107, and the corresponding set of perforated blocks 106. At this time, both sets of moving rectangular blocks 110 will cause the corresponding springs 109 to undergo elastic deformation under the cooperation of the corresponding perforated blocks 106 and the corresponding connecting blocks 105. When both sets of rectangular blocks 110 have completely moved inside the corresponding connecting blocks 105, first use the controller to simultaneously turn off both electric push rods 103. At this time, both turned-off electric push rods 103 will cause both sets of rectangular blocks 110 to stop moving under the cooperation of the above-mentioned components. Then dock the auxiliary tool to be installed with the entire quick-change mechanism 1. Next, use the controller to simultaneously start both electric push rods 103. At this time, both started electric push rods 103 will drive the corresponding round plates 104 to move back to their original positions. And both round plates 104 moving back to their original positions will cause the corresponding set of rectangular blocks 110 to move back to their original positions under the cooperation of the corresponding connecting blocks 105, the corresponding three-way pipes 107, the corresponding three-headed ropes 108, the corresponding perforated blocks 106, and the resilience of the corresponding springs 109. When both sets of rectangular blocks 110 have returned to their original positions, use the controller to simultaneously turn off both electric push rods 103. At this time, the auxiliary tool can be installed on the skid steer loader under the cooperation of the entire quick-change mechanism 1. When the auxiliary tool needs to be removed from the skid steer loader, just perform the reverse operation according to the above operation steps. When the two electric push rods 103 need to be repaired, first remove all the hand-tightening bolts 204. Then remove the two protective shells 202. At this time, both removed protective shells 202 will drive the corresponding two flat plates 203 to move together. At the same time, both removed protective shells 202 will drive the corresponding rubber strips 205 to move together. And two of the moving rubber strips 205 will separate from the corresponding perforated plates 201, and the other two moving rubber strips 205 will separate from the corresponding connecting blocks 105. Then remove both electric push rods 103 from the mounting blocks 102. Next, remove both round plates 104 from the corresponding electric push rods 103. At this time, the two electric push rods 103 can be moved away for repair. And both moving electric push rods 103 will drive the corresponding perforated plates 201 to move. When both electric push rods 103 are repaired,Just perform the reverse operation directly according to the above operation steps, and reset both repaired electric push rods 103 to their original positions.

[0025] Working principle: When it is necessary to install the auxiliary tool on the skid steer loader, first install the mounting plate 101 at a suitable position on the skid steer loader. Then connect both electric push rods 103 to the controller (PLC controller) on the skid steer loader. Next, use the controller to start both electric push rods 103 simultaneously. At this time, both started electric push rods 103 will drive the other ends of the corresponding three-headed ropes 108 to move under the cooperation of the corresponding circular plates 104. At this time, the other ends of both moving three-headed ropes 108 will drive the corresponding group of rectangular blocks 110 to move towards each other inside the corresponding connecting blocks 105 under the cooperation of the corresponding connecting blocks 105, the corresponding three-way pipes 107, and the corresponding group of perforated blocks 106. At this time, both groups of moving rectangular blocks 110 will cause the corresponding springs 109 to undergo elastic deformation under the cooperation of the corresponding perforated blocks 106 and the corresponding connecting blocks 105. When both groups of rectangular blocks 110 have completely moved inside the corresponding connecting blocks 105, first use the controller to turn off both electric push rods 103 simultaneously. At this time, both turned-off electric push rods 103 will cause both groups of rectangular blocks 110 to stop moving under the cooperation of the above-mentioned components. Then dock the auxiliary tool to be installed with the entire quick-change mechanism 1. Next, use the controller to start both electric push rods 103 simultaneously. At this time, both started electric push rods 103 will drive the corresponding circular plates 104 to move back to their original positions. And both circular plates 104 moving back to their original positions will cause the corresponding group of rectangular blocks 110 to move back to their original positions under the cooperation of the corresponding connecting blocks 105, the corresponding three-way pipes 107, the corresponding three-headed ropes 108, the corresponding perforated blocks 106, and the resilience of the corresponding springs 109. When both groups of rectangular blocks 110 have returned to their original positions, use the controller to turn off both electric push rods 103 simultaneously. At this time, the auxiliary tool can be installed on the skid steer loader under the cooperation of the entire quick-change mechanism 1. When it is necessary to remove the auxiliary tool from the skid steer loader, just perform the reverse operation according to the above operation steps. When the two electric push rods 103 need to be repaired, first remove all the hand-tightening bolts 204. Then remove the two protective shells 202. At this time, both removed protective shells 202 will drive the corresponding two flat plates 203 to move together. At the same time, both removed protective shells 202 will drive the corresponding rubber strips 205 to move together. And two of the moving rubber strips 205 will separate from the corresponding perforated plates 201, and the other two moving rubber strips 205 will separate from the corresponding connecting blocks 105. Then remove both electric push rods 103 from the mounting block 102. Next, remove both circular plates 104 from the corresponding electric push rods 103. At this time, the two electric push rods 103 can be moved away for repair. And both moving electric push rods 103 will drive the corresponding perforated plates 201 to move. When both electric push rods 103 are repaired,Just perform the reverse operation according to the above operation steps, and reset both of the repaired electric push rods 103 to their original positions.
