When the first slide rail 22 is rotated 90 degrees clockwise, the extrusion lug 55 is driven to rotate clockwise, when the protruding part of the extrusion lug 55 is not extruded on the inclined plane of the lower part of the moving frame 52 any more, the elastic piece 53 which is stretched at the moment is reset to drive the sliding block 51 and the moving frame 52 to move leftwards, the moving frame 52 moves leftwards to drive the positioning block 54 to move leftwards, the positioning block 54 is enabled to move to the front of the mechanical clamp 23, then when a user puts the catheter into the mechanical clamp 23, the end part of the catheter is close to the positioning block 54, under the positioning effect of the positioning block 54, people can prevent the end part of the catheter from being too close to the lower part of the first slide rail 22 when the catheter is placed, if the end part of the catheter is too close to the lower part of the first slide rail 22, the first slide rail 22 is driven to rotate anticlockwise when the first slide rail 22 rotates anticlockwise, the end part of the catheter is enabled to be in contact with the top of the supporting frame 1, so that the end part of the catheter is difficult to rotate to be in a vertical state with the ground, the position of the catheter can be located above the hole, then the positioning block 54 can be enabled to rotate rightwards just above the position of the positioning block, then the positioning block 54 can not rotate rightwards, the protruding piece 52 is prevented from being driven to move rightwards, and the first slide rail 52 is prevented from rotating anticlockwise, the protruding part of the first slide rail 52 is prevented from moving the protruding part is not to move the protruding part of the first slide rail 52, and the first slide rail 52 is prevented from rotating anticlockwise when the position of the protruding part is moved.
As shown in fig. 10-11, the device further comprises a limiting mechanism for limiting the supporting piece 31, the limiting mechanism is arranged between the second sliding rail 3 and the supporting frame 1, the limiting mechanism comprises a fixing rod 61, the fixing rods 61 are respectively and fixedly connected to the top of the second sliding rail 3, limiting pieces 62 are connected to the fixing rods 61 in a sliding mode, clamping holes are formed in the front side and the rear side of the lower portion of the supporting piece 31 in a sliding mode, the lower portion of the limiting pieces 62 are matched with the clamping holes in a clamping mode, second extension springs 63 are connected between the upper portion of the limiting pieces 62 and the fixing rods 61, wedge plates 6 are connected to the second racks 43, and the wedge plates 6 are matched with the upper portions of the limiting pieces 62 in an extrusion mode.
When the supporting piece 31 drives the second clamping piece 36 to clamp the catheter, the position of the supporting piece 31 can still slide in the second sliding rail 3, if people push the supporting piece 31 outwards carelessly, the second clamping piece 36 can directly loosen the catheter, so that the second clamping piece 36 can be influenced to clamp the catheter, the second clamping piece 36 can not stably clamp the catheter, the operation of uniformly lowering the catheter through the second clamping piece 36 can be directly influenced, and therefore, the limiting mechanism is arranged and used for limiting the supporting piece 31, the situation that the second clamping piece 36 accidentally loosens the catheter when clamping the catheter is avoided, and the following limiting mechanism is operated according to the working principle:
When the second rack 43 moves outwards, the wedge plate 6 is driven to move outwards, the second rack 43 also drives the supporting piece 31 to move inwards automatically through the cooperation of the gear 42 and the first rack 4, when the inclined surface of the wedge plate 6 contacts with the upper part of the limiting piece 62, the supporting piece 31 is just close to the limiting piece 62, the inclined surface of the wedge plate 6 lifts the limiting piece 62 upwards, the second extension spring 63 is stretched, at the moment, the supporting piece 31 continues to move inwards, then the clamping hole on the supporting piece 31 moves to the position below the limiting piece 62, and then after the inclined surface of the wedge plate 6 is separated from the limiting piece 62, the limiting piece 62 is driven to move downwards and clamp into the clamping hole under the action of the second extension spring 63, so that the position of the supporting piece 31 can be locked, the position of the second clamping piece 36 is limited, the second clamping piece 36 can clamp a catheter better and the catheter is lowered at a constant speed; then, when the second rack 43 moves inwards, the wedge plate 6 is driven to move inwards, when the inclined surface of the wedge plate 6 contacts with the upper part of the limiting piece 62, the limiting piece 62 is lifted upwards and separated from the supporting piece 31, the second extension spring 63 is stretched again, at the moment, the second rack 43 is just meshed with the gear 42, the supporting piece 31 is driven to move outwards for resetting, and then after the inclined surface of the wedge plate 6 is separated from the upper part of the limiting piece 62, the second extension spring 63 drives the limiting piece 62 to move downwards for resetting; in summary, the limiting member 62 can be moved downward to be clamped into the clamping hole to limit the supporting member 31, so as to avoid the displacement of the supporting member 31, which results in the second clamping member 36 not being capable of clamping the catheter.
As shown in fig. 12, the device further comprises four fixing blocks 7, the four fixing blocks 7 are respectively connected to the upper side and the lower side of the mechanical clamp 23 in a bilateral symmetry manner, a second threaded rod 73 is rotatably connected between the two fixing blocks 7 on the left side, a second guide rod 71 is fixedly connected between the two fixing blocks 7 on the right side, a second limiting plate 72 is slidably connected to the second guide rod 71, and the left part of the second limiting plate 72 is in threaded connection with the second threaded rod 73.
When the mechanical clamp 23 moves down and inserts the catheter into the fixing ring of the last catheter, the lower end of the catheter is difficult to insert downwards due to the fact that the inner wall of the fixing ring is provided with a plurality of thread grooves, the lower end of the catheter is difficult to insert downwards due to the resistance of the thread grooves when inserted into the fixing ring, the inner wall of the mechanical clamp 23 and the outer wall of the catheter are smooth, the mechanical clamp 23 is quite likely to be incapable of forcedly inserting the catheter due to the fact that the catheter is blocked, and therefore the second limiting plate 72 is arranged, when the problems occur, people can manually rotate the second threaded rod 73, the second threaded rod 73 drives the second limiting plate 72 to move downwards, the top of the catheter is forcedly pushed downwards after the second limiting plate 72 moves downwards and the top of the catheter is attached to the top of the catheter, so that the catheter can be assisted to insert into the fixing ring of the last catheter to be butted, and then the second threaded rod 73 is reversed to drive the second limiting plate 72 to move upwards to reset.
