Specifically, the first rotating member comprises a support plate 4, a first support rod 5 and a first torsion spring 6, the support plate 4 is vertically installed on the upper side of the support seat 1, one end of the first support rod 5 is fixedly connected to the support plate 4, and the other end points away from the support plate 4 and parallel to the front-to-back direction of the control frame 2; the left end of the lower side of the control frame 2 is provided with a first extension portion 21 extending downward, and the end of the support rod away from the support plate 4 vertically passes through the first extension portion 21, and is rotatably connected to the first extension portion 21; the first torsion spring 6 is sleeved on the first support rod 5, one end of which is fixedly connected to the first support rod 5, and the other end is fixedly connected to the first extension portion 21. The operating frame 2 can rotate relative to the supporting base 1 under the action of the first rotating member.

[0024] A second rotating member is installed at the right end of the lower side of the operating frame 2. The operating frame 2 is connected to the operating hook 7 through the second rotating member. Specifically, the second rotating member includes a second support rod 8 and a second torsion spring 9. The right end of the lower side of the operating frame 2 is provided with a second extension portion 22 extending to the right. One end of the second support rod 8 is fixedly connected to the second extension portion 22, and the other end is directed away from the second extension portion 22 and parallel to the front-rear direction of the operating frame 2. This end of the second support rod 8 vertically passes through the operating hook 7 and is rotatably connected to the operating hook 7. The second torsion spring 9 is sleeved on the second support rod 8, one end of which is fixedly connected to the second support rod 8, and the other end is fixedly connected to the operating hook 7. The operating hook 7 can rotate relative to the operating frame 2 under the action of the second rotating member. One end of the operating hook 7 is rotatably connected to the second support rod 8 in the second rotating member, and the other end is directed vertically downward and bent toward the left end of the operating frame 2, so that the hook mouth of the operating hook 7 faces upward. The rotation direction of the operating hook 7 is the same as that of the operating frame 2. In the present invention, by providing the first torsion spring 6 of the first rotating member and the second torsion spring 9 of the second rotating member, the operating frame 2 and the operating hook 7 can maintain balance and stability in a certain state.

[0025] The hook body of the operating hook 7 is provided with a hook groove 71, the hook groove 71 is far away from the hook tip, and its groove is facing the left end of the operating frame 2; the hook body of the operating hook 7 is arc-shaped, its concave surface is facing the left end of the operating frame 2, and the hook groove 71 is provided on the concave surface.

The setting of the handle rod 20 can facilitate the control of the operating hook 7 and the operating frame 2.

[0026] A fixing rod 30 is also installed on the upper side of the support seat 1. The fixing rod 30 is connected to the support seat 1 through a first connecting member 301. The fixing rod 30 is parallel to the upper side of the support seat 1 and is arranged at intervals. The fixing rod 30 is parallel to the front and rear directions of the operating frame 2 and is hung in the hook mouth of the operating hook 7. In the present invention, by setting the first torsion spring 6 of the first rotating member, the second torsion spring 9 of the second rotating member, and the fixing rod 30, after the fixing rod 30 is hung in the hook mouth of the operating hook 7, the operating hook 7 gives an upward force to the fixing rod 30, so that the operating frame 2 and the operating hook 7 maintain balance and stability. At this time, the upper side of the operating frame 2 is at an angle of 45-30 degrees to the upper side of the support seat 1. When force is applied to the handle bar 20 to move the operating handle 10 so that the operating hook 7 and the operating frame 2 rotate in the clockwise direction, the hook mouth of the operating hook 7 rotates and moves in the lower left direction, and the inner arc surface of the operating hook 7 keeps in contact with the fixing rod 30, and finally the fixing rod 30 is disengaged from the hook mouth and stably hung in the hook groove 71 of the operating hook 7. At this time, the upper side surface of the operating frame 2 is parallel to the upper side surface of the support seat 1. Preferably, a groove 40 is provided on the upper side surface of the support seat 1, and the groove 40 is directly opposite to the operating hook 7. The depth of the groove 40 is not less than the length of the operating hook 7. After the hook mouth of the operating hook 7 rotates and moves in the lower left direction, it can penetrate into the groove 40, so that the operating hook 7 does not affect the normal use of the present invention. When force is applied to the handle rod 20 again to move the operating handle 10 so that the operating hook 7 and the operating frame 2 rotate in the clockwise direction and the fixing rod 30 is disengaged from the hook groove 71, the force applied to the handle rod 20 is stopped, and the operating frame 2 and the operating hook 7 are reset under the action of the first torsion spring 6 and the second torsion spring 9, so that the fixing rod 30 is re-hook in the hook mouth of the operating hook 7.

[0027] A fixing plate 50 is also installed on the upper side of the support seat 1. The fixing plate 50 is connected to the support seat 1 through a second connecting member 501. The fixing plate 50 is parallel to the upper side of the support seat 1. The fixing plate 50 is located between the first rotating member and the fixing rod 30. A connecting piece 60 is vertically connected to the middle end of the lower side of the operating frame 2. The connecting piece 60 is located directly above the fixing plate 50. A micro switch 601 is detachably installed on one end of the connecting piece 60 facing the fixing plate 50. The micro switch 601 is directly opposite to the fixing plate 50. When the fixing rod 30 is hung in the hook mouth of the operating hook 7, the micro switch 601 is away from the fixing plate 50 to be in a disconnected state. When the fixing rod 30 is hung in the hook groove 71 of the operating hook 7, the micro switch 601 abuts against the fixing plate 50 to be in a connected state. Therefore, in the present invention, the operator can apply force to the handle rod 20 to rotate the operating frame 2 and the operating hook 7, so that the fixing rod 30 is hung in the hook mouth or hook groove 71 of the operating hook 7, thereby realizing the connection and disconnection of the micro switch 601, making the operation more convenient and the use reliability higher, avoiding misoperation.

[0028] The above description is a detailed description of the preferred feasible embodiments of the present invention, but the embodiments are not intended to limit the scope of the patent application of the present invention. All equivalent changes or modified changes completed under the technical spirit suggested by the present invention should fall within the patent scope covered by the present invention.
