[0026] In the embodiment, the fixing mechanism 5 comprises two symmetrically arranged arc-shaped clamping plates 51, the middle part of the side face away from each other of the two arc-shaped clamping plates 51 is fixedly connected with a connecting rod 52, the inside of the base 1 and the corresponding positions of the two connecting rods 52 are provided with connecting grooves, the connecting grooves are matched with the connecting rods 52, one end of the connecting rod 52 away from the arc-shaped clamping plate 51 extends to the inside of the connecting groove, the end of the connecting rod 52 extending to the inside of the connecting groove is fixedly connected with a spring 53, and the end of the spring 53 away from the connecting rod 52 is fixedly connected to the inner wall of the base 1.
[0027] In order to facilitate the insertion of the magnetic control key 4 into the inside of the mounting groove 3, the top of the side face close to each other of the two arc-shaped clamping plates 51 can be provided as an inclined surface or the side face close to each other of the two arc-shaped clamping plates 51 can be provided as an arc-shaped surface (not shown in the figure), so that when the magnetic control key 4 is inserted, the bottom of the magnetic control key 4 first contacts the inclined surface or the arc-shaped surface of the arc-shaped clamping plate 51, facilitating the insertion of the magnetic control key 4.
[0028] In the embodiment, the end of the connecting rod 52 extending to the connecting groove is fixedly connected with a limiting sliding block 54 on both sides, the inside of the base 1 is provided with a limiting sliding groove 55 in communication with the connecting groove, and the limiting sliding block 54 is slidingly connected to the inside of the limiting sliding groove 55.
[0029] Under the cooperation of the limiting sliding block 54 and the limiting sliding groove 55, the movement of the connecting rod 52 can be guided, the deviation of the connecting rod 52 in the movement process can be prevented, and the connecting rod 52 can also be prevented from moving out of the connecting groove in the movement.
[0030] In the embodiment, the process of putting the magnetic control key 4 into the mounting groove 3 is as follows:
[0031] When the magnetic key 4 is inserted into the installation groove 3, the magnetic key 4 will press the arc-shaped clamping plates 51, the arc-shaped clamping plates 51 will push the connecting rods 52 to move away from the magnetic key 4, and the connecting rods 52 can press the springs 53 when moving in the connecting grooves, and the springs 53 pressed when the magnetic key 4 is completely inserted into the installation groove 3 can also provide a reaction force to the connecting rods 52 and the arc-shaped clamping plates 51, so that the arc-shaped clamping plates 51 abut against the surface of the magnetic key 4, and at this time the magnetic key 4 is clamped in the installation groove 3 under the action of the two arc-shaped clamping plates 51.
[0032] In the embodiment, in order to further fix the magnetic key 4 more firmly, the base 1 is provided with a limiting mechanism 6 for limiting the magnetic key 4, one side of the base 1 is provided with a sliding groove 11, the limiting mechanism 6 comprises a threaded rod 61, one end of the threaded rod 61 is rotatably connected to the base 1 through a bearing, and the threaded rod 61 is located in the sliding groove 11, the limiting mechanism 6 further comprises an L-shaped sliding rod 62, one end of the L-shaped sliding rod 62 is provided with a threaded hole matched with the threaded rod 61, the L-shaped sliding rod 62 is threadedly connected to the threaded rod 61 through the threaded hole, and the L-shaped sliding rod 62 is slidably connected in the sliding groove 11, the L-shaped sliding rod 62 cooperates with the sliding groove 11 to prevent the L-shaped sliding rod 62 from rotating with the threaded rod 61 when the threaded rod 61 rotates, but drives the L-shaped sliding rod 62 to slide in the sliding groove 11 when the threaded rod 61 rotates;
[0033] The other end of the threaded rod 61 penetrates through the base 1 and extends to the outside of the base 1, and a hand wheel 63 is fixedly connected to the other end of the threaded rod 61, and a gap is left between the hand wheel 63 and the base 1, and the gap can meet the rotation condition of the hand wheel 63;
[0034] Anti-skid lines are arranged on the outer surface of the hand wheel 63, the friction coefficient of the hand wheel 63 is increased through the anti-skid lines, the user can hold the hand wheel 63 more stably, and the slipping condition can be reduced;
[0035] After the magnetic key 4 is fixed in the installation groove 3, the hand wheel 63 is rotated clockwise in the process of rotation, the threaded rod 61 is rotated clockwise in the process of rotation, the L-shaped sliding rod 62 threadedly connected to the threaded rod 61 is moved in the sliding groove 11 to the direction close to the magnetic key 4 in the process of rotation of the threaded rod 61, until the end of the L-shaped sliding rod 62 away from the threaded rod 61 abuts on the magnetic key 4, at this time the magnetic key 4 can be prevented from falling from the installation groove 3 under the limiting action of the L-shaped sliding rod 62, and the magnetic key 4 is fixed more firmly in the installation groove 3;
[0036] When the magnetic key 4 needs to be used, the L-shaped sliding rod 62 is no longer abutted on the magnetic key 4 by counterclockwise rotating the hand wheel 63, and the magnetic key 4 can be taken out through the round hole of the magnetic key 4.
[0037] Therefore, the magnetic control key 4 can be prevented from being lost, and the magnetic control key 4 can be worn on the wrist of the medical staff during work, and the limiting mechanism 6 can be released from limiting the magnetic control key 4 by counterclockwise rotating the hand wheel 63 during use, and then the magnetic control key 4 can be taken off and used through the round hole on the magnetic control key 4, the magnetic control key 4 can be worn on the wrist of the medical staff, and is not placed alone, and the magnetic control key 4 does not need to be taken from the placement area during use, and the magnetic control key 4 is convenient to use.
[0038] All the technical features in the embodiment can be freely combined according to actual needs.
[0039] The above embodiment is a preferred implementation scheme of the utility model, and the utility model can also be implemented in other manners, and any obvious replacement without departing from the technical scheme concept is within the protection scope of the utility model.
