Specifically, when the reset lever 40 is at the abutting position, the limiting slot 411 is opposite to the second mounting hole 13, and the limiting portion 52 is clamped into the limiting slot 411 under the action of the second reset spring 60. When the operation portion 51 is pushed, the limiting portion 52 overcomes the force of the second return spring 60 and exits the limiting slot 411, and under the action of the first return spring 30, the return connection portion 22 pushes the return lever 40 to move toward the avoiding position, so that the clamping member 20 is in the clamped state.

When the clamping piece 20 needs to be switched to the unlocking state, the reset rod 40 is pressed to push the reset connecting portion 22 of the clamping piece 20, and when the clamping piece 20 moves from the clamping state to the unlocking state, the limiting groove 411 is opposite to the second mounting hole 13, and at the moment, the limiting portion 52 is clamped into the limiting groove 411 under the action of the second reset spring 60. Thereby restricting the reset lever 40 to the abutment position to hold the latch 20 in the unlocked state, at this time, the medical instrument mounted on the medical cart can be detached by both hands, thereby further improving the convenience of use of the medical cart. Of course, in other embodiments, the lever 50 may not be provided with the operation portion 51 and may not protrude from the second mounting hole 13.

When the third return spring 80 is sleeved on the return rod 40, two ends of the third return spring 80 can be more stably abutted against the first limiting part 52 and the second limiting part 52, and the return rod 40 is further more stably driven to move from the abutting position to the avoiding position. Of course, in other embodiments, the second limiting portion 52 of the reset lever 40 may also be disposed on a side of the first limiting portion 52 near the clamping member 20.

In some embodiments, the reset lever 40 includes a large-diameter section 41 and a small-diameter section 42, one end of the large-diameter section 41 is located in the first mounting hole 11, the large-diameter section 41 is provided with a limiting slot 411, the large-diameter section 41 is connected with the small-diameter section 42, a second limiting portion 52 is formed at the connection position of the large-diameter section 41 and the small-diameter section 42, and the third reset spring 80 is sleeved on the small-diameter section 42.

Specifically, the stop lever 50 is connected to the large diameter section 41, and the third return spring 80 is sleeved on the small diameter section 42. Thus, the third return spring 80 does not interfere with the stop lever 50 when the user operates the stop lever 50, and the third return spring 80 does not interfere with the stop lever 50 when the third return spring 80 urges the return lever 40 to move from the abutment position to the escape position. In this way, the stopper rod 50 and the third return spring 80 can be used more stably. Of course, in other embodiments, a limiting bump is disposed on a peripheral side of the reset lever 40, and the third reset spring 80 abuts against the limiting bump and the first limiting portion 52.

4. The locking device according to claim 3, wherein the reset lever is provided with a through hole, the through hole penetrates through the bottom wall of the limit groove, the limit lever is movably arranged through the through hole, the size of the through hole in the length direction of the reset lever is larger than that of the limit lever, the limit portion is located at one side of the reset lever, which is opposite to the operation portion, the locking device further comprises a limit plate, the limit plate covers one end, far away from the operation portion, of the second mounting hole, and the second reset spring is abutted between the limit lever and the limit plate and is in a compressed state.

5. A locking device as claimed in claim 3, further comprising a third return spring disposed between the return lever and the mounting base and having an elastic deformation urging the return lever from the abutment position toward the retracted position.

6. The locking device of claim 5, wherein the third return spring is sleeved on the return lever and abuts between the return lever and the mounting base.

7. The locking device of claim 5, wherein a first limiting portion is disposed in the first mounting hole, a second limiting portion is disposed at a portion of the reset lever located in the first mounting hole, the second limiting portion is located at a side of the first limiting portion away from the clamping piece, and the third reset spring is abutted between the first limiting portion and the second limiting portion.

8. The locking device of claim 5, wherein the reset lever comprises a large-diameter section and a small-diameter section, one end of the large-diameter section is positioned in the first mounting hole, the large-diameter section is provided with the limit groove, the large-diameter section is connected with the small-diameter section, a second limit part is formed at the connection part of the large-diameter section and the small-diameter section, the orifice of one side of the first mounting hole, which is close to the clamping piece, is smaller than the orifice of the other side of the first mounting hole, so as to form the second limit part, and the third reset spring is sleeved on the small-diameter section.

9. A medical trolley comprising a support body and a locking device according to any one of claims 1 to 8, the support body having a support top plate provided with a via hole, the locking device being mounted below the support top plate and a hook portion of the locking device extending from the via hole.

10. The medical cart of claim 9, wherein the support body includes a base, a support bar, and a mounting case, the lower end of the support bar being connected to the base, the mounting case being mounted to the upper end of the support bar and having an upward opening, the locking device being mounted in the mounting case, the support top plate being covered by the opening.
