When the isolation seat 2 needs to be detached from the driving seat 1, only the pressing rod 1221 needs to be pressed, the linkage block 122 moves downwards to drive the linkage button 123 to move downwards, so that the linkage button 123 moves out of the clamping hole 24 of the isolation seat 2, and at the moment, the isolation seat 2 is pushed in the direction opposite to the mounting direction, so that the isolation seat 2 is separated from the driving seat 1. When the pressing rod 1221 is not stressed any more, the pressing rod 1221 and the link button 123 are reset by the spring.
As shown in fig. 2 and 3, the driving seat 3 and the isolating seat 2 are quickly connected through a second quick release structure.
The second quick release structure comprises a third positioning portion, wherein the third positioning portion comprises a fourth sliding groove 31 arranged at the bottom of the transmission seat 3 and a second sliding block 25 arranged on the isolation seat 2. The second slider 25 can be accommodated in the fourth slide groove 31 and slide along the fourth slide groove 31.
The fourth runner 31 is configured in two portions of unequal width, a wider portion being near one end of the implement attachment mechanism 4 and a narrower portion being away from one end of the implement attachment mechanism 4, the wider portion and the narrower portion forming a step 32 therebetween. The first slide block 21 of the isolation seat 2 is symmetrically provided with first positioning blocks 26 at two sides, and the first positioning blocks 26 comprise inclined grooves 261 and protruding parts 262 (shown in fig. 6) positioned at the ends of the inclined grooves 261. During the process of introducing the second slider 25 into the fourth slide groove 31, the first positioning block 26 can abut on the step 32 of the fourth slide groove 31, thereby limiting the movement range of the transmission seat 3 in the X direction. Thus, the driving seat 3 and the spacer 2 are completely positioned in the Y-axis direction and the X-direction by the second slider 25 and the fourth slide groove 31.
Further, the second quick release structure further includes a fourth positioning portion, the fourth positioning portion includes a projection 33 disposed at one end of the fourth sliding groove 31 far away from the apparatus connecting mechanism 4 (the projection 33 is located on the plane where the lower surface of the transmission seat 3 is located), a groove 27 is disposed at one end of the second sliding block 25 far away from the apparatus connecting mechanism 4, and when the transmission seat 3 slides to the state of being assembled with the isolation seat 2, the projection 33 can be accommodated in the groove 27. So that the isolation seat 2 and the transmission seat 3 are completely positioned in the Z-axis direction.
In order to facilitate the smooth guiding of the second slider 25 into the fourth sliding groove 31, a downwardly inclined guiding inclined surface 251 is provided at an end of the second slider 25 away from the implement connecting mechanism 4 to reduce resistance when the second slider 25 enters the fourth sliding groove 31, thereby improving assembly efficiency.
As shown in fig. 7 and 8, the two sides of the driving seat 3 are symmetrically provided with the second quick release assemblies 34, each second quick release assembly 34 includes a button 341, a guide block 342, a stop 343, and a small cylinder 344, which are connected in sequence, and the button 341, the guide block 342, the stop 343, and the small cylinder 344 are integrally formed. The small cylinder 344 is disposed at the center of the stopper 343, and preferably, the end surface of the stopper 343 on which the small cylinder 344 is disposed is provided with a first locking groove 3441 to limit unnecessary movement of the spring. The guide block 342 further includes an inclined portion 3421 (inclined upward) and a flat portion 3422, and the inclined portion 3421 allows the button 341 to always end up on the upper side of the first positioning block 26 so as not to interfere with the first positioning block 26. A long groove 3423 is provided at the middle position of the flat surface part 3422, and a second positioning block 345 is provided on the lower surface of the joint of the inclined part 3421 and the flat surface part 3422. The width of the second positioning block 345 is smaller than the width of the chute 221, and when the lower surface of the transmission seat 3 contacts the upper surface of the isolation seat 2 and slides relatively along the X-axis, the second positioning block 345 is always located above the first positioning block 26. So that the second positioning block 345 can smoothly pass through the inclined groove 221 when the driving seat moves in the X-axis direction.
As shown in fig. 9, a guide groove 35 is provided on the transmission base 3 at a position corresponding to the second quick release assembly 34, and the flat portion 3422 of the guide block 342 can be received in the guide groove 35, so that the guide block 342 can move in the guide groove 35 along the Y-axis direction.
As shown in fig. 10, springs (not shown) are sleeved between the small cylinders 344 of the two first quick release assemblies 34, and the springs respectively abut against the stop 343 of each second quick release assembly 34. Preferably, the springs abut in the first catching grooves 3441, respectively. When the button 341 is released, the spring can quickly reset the two second quick release assemblies 34. As shown in fig. 11, when the transmission seat 3 and the isolation seat 2 are installed, the second positioning block 345 is clamped on the protrusion 222.
The transmission seat 3 and the isolation seat 2 are installed in the following way:
the lower surface of the transmission seat 3 is in contact with the upper surface of the isolation seat 2, the transmission seat 3 is pushed along the length direction (i.e. the X-axis direction) of the isolation seat 2, in the moving process of the transmission seat 3, the second positioning block 345 on the second quick release assembly 34 enters the chute 261 of the first positioning block 26 (close to the outer side of the chute 261), and under the limiting and guiding effects of the chute 261, the spring of the second quick release assembly 34 is gradually compressed to move the second positioning block 345 towards the direction close to the second slider 25, so that the second positioning block 345 can smoothly pass through the narrow part of the chute 261. The second positioning block 345 passes through the inclined slot 261 and then is reset under the action of the spring, and at the moment, the second positioning block 345 is just clamped on the projection 262 of the first positioning block 26, so that the transmission seat 3 is prevented from moving reversely to the X axis. And at this time, the projection 33 on the fourth sliding chute 31 and the groove 27 on the second sliding block 25 are just matched. At this time, the driving seat 3 and the isolation seat 2 are installed.
When the transmission seat 3 needs to be detached from the isolation seat 2, the buttons 341 on both sides are pressed simultaneously, at this time, the second positioning block 345 is no longer limited by the protruding portion 262 of the first positioning block 26, the transmission seat 3 is pushed along the X-axis negative direction, the second positioning block 345 passes through the chute 261, at this time, the button 341 can be loosened, and the transmission seat 3 is continuously pushed along the X-axis negative direction, so that the detachment of the transmission seat 3 and the isolation seat 2 can be realized.
The above description is only a preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art can easily make changes or variations within the technical scope of the present invention disclosed, and such changes or variations should be covered within the scope of the present invention.
