Example two
The difference between this embodiment and the first embodiment is:
referring to fig. 5, in the present embodiment, the fixing member 121 is provided with two extending walls 1212 respectively connected to two opposite sides of the first thread groove 1211, and the extending walls 1212 are formed by extending in a direction approaching the movable member 122; moveable member 122 is in sliding engagement with at least one of the extending walls 1212; a tension spring (not shown) is provided between the movable member 122 and the fixed member 121, and provides an elastic force for sliding the movable member 122 in a direction approaching the fixed member 121.
By adopting the above scheme, the switching between the open state and the closed state of the movable element 122 can be realized by controlling the movable element 122 to slide along the extension wall 1212 in sliding contact with the movable element, and the switching operation of the states of the movable element 122 is very convenient, wherein the tension spring is always in a stretching state in the process that the movable element 122 slides along the extension wall 1212 in sliding contact with the movable element 122, that is, the tension spring can always provide the elastic force for the movable element 122 to slide in the direction of approaching the fixed element 121.
Based on this, when the base 21 needs to be installed on any platform 30, the base 21 is placed on the platform 30, and then the movable element 122 is controlled to slide along the extending wall 1212 in sliding contact with the base towards the side away from the fixed element 121, so that the movable element 122 is in an open state, the second thread groove 1221 and the first thread groove 1211 are separated from each other, so as to allow the adjusting screw 11 to directly move between the second thread groove 1221 and the first thread groove 1211, during which the tension spring is further stretched and further accumulates a certain elastic force, at this time, the adjusting screw 11 can be rapidly controlled to move towards the base 21 and the platform 30 to rapidly reduce the clamping gap, so that the adjusting screw 11 is very close to the platform 30; subsequently, the movable element 122 is controlled to slide towards one side close to the fixed element 121 along the extending wall 1212 in sliding contact with the movable element, so that the movable element 122 is in a closed state, and the second thread groove 1221 and the first thread groove 1211 are closed to form a threaded hole, during which the torsion spring 14 recovers a certain deformation and releases a certain elastic force to assist in driving the movable element 122 to slide towards one side close to the fixed element 121, at this time, the adjusting screw 11 is screwed into the threaded hole, and the adjusting screw 11 can be brought into close contact with the platform 30 by rotating the adjusting screw 11 a few turns in the forward direction, so that the purpose of clamping the platform 30 together by the adjusting screw 11 and the base 21 to mount the base 21 on the platform 30 can be achieved.
In the process of switching the movable element 122 from the open state to the closed state, the control on the movable element 122 may also be cancelled, so that the movable element 122 automatically slides along the extending wall 1212 in sliding contact with the movable element toward the side close to the fixed element 121 under the elastic force of the tension spring, so as to switch the movable element 122 to the closed state.
Wherein, at the in-process of rotating adjusting screw 11, the thread on adjusting screw 11 can produce the reverse effort that makes it deviate from base 21 to moving part 122, the extension spring that is stretched simultaneously can provide the gliding elastic force of one side that makes it be close to mounting 121 for moving part 122, and then realize moving part 122's auto-lock under the combined action of adjusting screw 11's reverse effort and the elastic force of extension spring, make moving part 122 stabilize in the closure state, so, greatly reduce the risk that the pine takes off appears in moving part 122 that is in the closure state, guarantee effectively adjusting screw 11 and base 21's centre gripping locking effect, guarantee base fixing device 10's performance effectively.
On the contrary, when the base 21 installed on the platform 30 needs to be disassembled, firstly, the adjusting screw 11 can be selectively rotated reversely for a few circles, so as to reduce the reverse acting force of the screw teeth on the adjusting screw 11 on the movable element 122, which makes the movable element 122 deviate from the base 21, and synchronously reduce the elastic force provided by the stretched torsion spring 14 for the movable element 122, which makes the movable element 122 slide towards one side close to the fixed element 121, so as to reduce the self-locking force of the movable element 122, and further facilitate the control of the movable element 122 to slide towards one side deviating from the fixed element 121 along the extending wall 1212 in sliding connection with the movable element 122, so as to switch the state of the movable element 122; subsequently, the movable element 122 is controlled to slide along the extending wall 1212 in sliding contact with the movable element to a side away from the fixed element 121, so that the movable element 122 is in an open state, the second thread groove 1221 and the first thread groove 1211 are separated from each other, and the adjusting screw 11 is allowed to directly move between the second thread groove 1221 and the first thread groove 1211, at this time, the adjusting screw 11 can be rapidly controlled to move away from the base 21 and the platform 30 to rapidly increase the clamping gap, so that the adjusting screw 11 is rapidly moved away from the platform 30, and the purpose of detaching the base 21 mounted on the platform 30 can be achieved.
Therefore, the state of the movable member 122 can be switched by controlling the movable member 122 to slide along the extension wall 1212 in sliding contact with the movable member, so as to close or separate the first thread groove 1211 and the second thread groove 1221, and further quickly adjust the size of the clamping gap to disassemble and assemble the base 21 on the platform 30.
