Referring to fig. 1 to 4, the present invention provides a dual-purpose fixture, comprising:

a base 100, the base 100 including a bottom plate 110 and a side plate 120 disposed on the bottom plate 110;

the clamping piece 200, the clamping piece 200 is connected with the side plate 120 through the rotating shaft 300, and the clamping piece 200 comprises a first clamping end 210 and a second clamping end 220 which are respectively positioned at two sides of the rotating shaft 300; when the clamping member 200 rotates in the working direction, the first clamping end 210 is close to the bottom plate 110 and forms a first clamping space together, and the second clamping end 220 is close to the side plate 120 and forms a second clamping space together;

and a fastening device which applies a force to the clip 200 in the working direction of the clip 200.

The working direction of the clamping member 200 refers to the rotation direction of the clamping member 200 when clamping is achieved, that is, the rotation direction of the clamping member 200 when the first clamping end 210 approaches the bottom plate 110.

In the solution of the present application, when the clamping member 200 rotates along the working direction, the first clamping end 210 is close to the bottom plate 110 and forms a first clamping space together, and the second clamping end 220 is close to the side plate 120 and forms a second clamping space together; the size of the first clamping space can be adjusted by adjusting the distance between the first clamping end 210 and the bottom plate 110 through the fastening means, and the size of the second clamping space can be adjusted by adjusting the distance between the second clamping end 220 and the side plate 120 through the fastening means, so that different size ranges can be accommodated. In addition, the first clamping space and the second clamping space can be respectively arranged in different shapes to adapt to different clamping shapes, one more fastening position is compared with the traditional clamp, and the application range of the installation environment is increased. And the first clamping space and the second clamping space are formed synchronously, and the operation is simple and convenient by one fastening device.

Further, one end of the bottom plate 110 is connected to one end of the side plate 120 to form an included angle, the rotation range of the first clamping end 210 is within the included angle formed by the bottom plate 110 and the side plate 120, and the rotation range of the second clamping end 220 is outside the included angle formed by the bottom plate 110 and the side plate 120. Both the side plate 120 and the bottom plate 110 can limit the first clamping end 210 in the rotation direction, and the first clamping end 210 can avoid excessive rotation at the included angle. In addition, the included angle formed by the portion of the first clamping end 210 for contacting the workpiece to be clamped and the portion of the second clamping end 220 for contacting the workpiece to be clamped should be equal to the included angle formed by the bottom plate 110 and the side plate 120 as much as possible, so that when the first clamping end 210 approaches the working position, the second clamping end 220 also approaches the working position.

The included angle formed by connecting one end of the bottom plate 110 with one end of the side plate 120 is also an included angle between the first clamping space and the second clamping space, the included angle is too small, which results in too small adjustable range of the clamping dimension, and the too large included angle results in interference between the rotation of the clamping member 200 and the medical product to be installed. In the present embodiment, the included angle formed by connecting one end of the bottom plate 110 and one end of the side plate 120 is preferably 70-110 degrees, wherein in the drawing of the present embodiment, the included angle is 90 degrees, and 90 degrees is the optimal angle in the present embodiment.

As a specific embodiment of the present invention, the second clamping end 220 includes a connection portion that mates with the rotating shaft 300 and a pressing portion disposed on the connection portion, where the connection portion and the pressing portion form a semi-closed clamping arm, and the clamping arm and the side plate 120 together form a second clamping space. The clamping arm in the drawings of the embodiment is an L-shaped arm, and the L-shaped arm and the side plate can form a rectangular clamping space for clamping the square tube 101. On the basis of the present embodiment, the clamping arm may be provided in other semi-closed shapes, as long as the clamping arm can be matched with the side plate 120 to stably clamp the workpiece to be clamped.

Further, a limiting groove 221 for matching with the second to-be-clamped piece 200 is formed on one side of the pressing part, which is close to the side plate 120. The specific shape of the limiting groove 221 is adapted to the specific shape of the outer contour of the workpiece to be clamped, for example, when the second clamping space is used for clamping the square tube, the limiting groove 221 can be a rectangular groove, and the rectangular limiting groove 221 can stop the square tube 101 to prevent the square tube 101 from loosening from the clamping position.

As a specific embodiment of the present invention, a side of the base plate 110 facing the first clamping end 210 is provided with a support groove for being matched with the first member to be clamped 200, and a side of the base plate 110 facing away from the first clamping end 210 is a mounting surface for connecting a device to be mounted. The mounting surface is provided with threaded holes (not shown) for attachment of the device.

As a preferred embodiment of the present invention, the first clamping space is used for clamping the round tube, so that the supporting groove is an arc-shaped groove, and the side of the first clamping end 210 facing the supporting groove is correspondingly provided with an arc-shaped compression surface. The first clamping end 210 forms a circular clamping space when adjacent to the arcuate support slot for clamping the tubular 102. However, the present invention is not limited thereto, and the supporting groove may be provided as a V-shaped supporting groove, a trapezoid supporting groove, a wave-shaped supporting groove, etc. for the purpose of clamping the round tube, and a side of the first clamping end 210 facing the supporting groove is correspondingly provided as a V-shaped compression surface, a trapezoid compression surface, a wave-shaped compression surface, etc. The shapes that can be conceived by those skilled in the art for achieving the gripping purpose when making the conventional choice shall fall within the scope of the present invention.

As one possible embodiment of the present invention (the first structure of the fastening device), the fastening device is a first torsion spring (not shown), and the first torsion spring is sleeved on the rotating shaft 300 and applies force to the clamping member 200 along the working direction of the clamping member 200. In this embodiment, the locking force is entirely from the first torsion spring, the clamp is in a closed clamping state, and when in use, the user needs to overcome the elastic force of the first torsion spring to rotate the clamping member 200 in a direction opposite to the working direction, specifically, can press one end of the clamping member 120 to rotate in a direction opposite to the working direction, and then place the to-be-clamped member into the first clamping space or the second clamping space.

As a further possible embodiment of the invention (second configuration of the fastening device), namely the embodiment of the fastening device shown in fig. 1 to 4: the base 100 further comprises a mounting seat 130 arranged on the side plate 120, wherein the mounting seat 130 and the bottom plate 110 are respectively positioned at two sides of the side plate 120; the fastening device comprises a threaded rod 410 rotatably arranged on the mounting seat and a pressing block 420 in threaded fit with the threaded rod 410, wherein the pressing block 420 can move along the threaded rod along with the rotation of the threaded rod; the second clamping end 220 is formed with a protrusion 230 on a side facing the fastening means, and the pressing block contacts the stopper protrusion 230 in the working direction of the clamping member 200.

As a modification of the embodiment described above (third structure of the fastening device), only the mounting manner of the threaded fastener is changed on the basis of the second structure of the fastening device: the pressing block 420 can be directly fixed on the threaded rod 410, the threaded rod 410 is in threaded fit with the mounting seat 130, and when the threaded rod 410 is rotated, the threaded rod 410 drives the pressing block 420 to linearly move together, so that the pressing block 420 contacts the stop lug 230 along the working direction of the clamping piece 200

In the second structure of the fastening device in the present application, the purpose of the mounting seat 130 is to mount the fastening device, and the fastening device in the present application includes a threaded rod 410 and a pressing block 420, where the threaded rod 410 may be matched with the mounting seat 130 through a bearing, and the threaded rod 410 only rotates in the mounting seat 130, and does not generate linear motion. The pressing block 420 is in surface contact with the mounting seat 130, so that the pressing block 420 cannot circumferentially rotate in the mounting seat 130, and a guide groove matched with the pressing block 420 can be specifically arranged in the mounting seat 130 to limit the circumferential rotation of the pressing block 420. When the threaded rod 410 is rotated, the pressing block 420 moves along the threaded rod 410 following the rotation of the threaded rod 410. In addition, a protrusion 230 is formed on a side of the second clamping end 220 facing the fastening device, the protrusion 230 is located on a side of the connecting portion facing away from the pressing portion, the shape of the protrusion 230 is such that the protrusion 230 can always contact with the pressing block 420 during the rotation of the clamping member 200, and the pressing block 420 is located on a side of the protrusion 230 near the side plate 120 such that the pressing block 420 contacts with the stopping protrusion 230 along the working direction of the clamping member 200.

Further, a second torsion spring (not shown) is sleeved on the rotating shaft 300, and the second torsion spring applies force to the clamping member 200 in a direction opposite to the working direction of the clamping member 200. The second torsion spring plays a role of restoring force, and when the threaded rod 410 is screwed in the loosening direction, the protrusion 230 moves toward the side plate 120 along with the pressing block 420 under the action of the second torsion spring.

Preferably, the end of the threaded rod 410 is provided with a quincuncial handle. Quincuncial twists are used to facilitate the user in rotating the threaded rod 410 to effect clamping or unclamping.

The foregoing description is only of the preferred embodiments of the present invention, and is not intended to limit the scope of the invention, but rather is intended to cover any equivalents of the structures or equivalent processes disclosed herein or in the alternative, which may be employed directly or indirectly in other related arts.
