[0056] Continue to refer Figure 1 and Figure 2 In this embodiment, the guide member 3 is in the shape of a rod. For the convenience of description, the length direction of the guide member 3 is defined as the longitudinal direction.

[0057] The clamping member 1 includes a moving rod 11 and two clamping arms 12 .

[0058] The moving rod 11 is movably connected to the guide member 3 and can move along the length direction of the guide member 3, that is, move along the longitudinal direction. In this embodiment, a mounting block 6 is provided on one side of the guide member 3 along the second direction, and the moving rod 11 is slidably connected to the mounting block 6. Specifically, the moving rod 11 is inserted into the mounting block 6 and slidably connected to the mounting block 6, and the moving rod 11 is parallel to the guide member 3 and spaced along the second direction. The second direction is perpendicular to the longitudinal direction. For ease of description, the second direction is defined as the vertical direction.

[0059] Furthermore, a fastener 7 is passed through the mounting block 6 and the moving rod 11 to limit the displacement of the moving rod 11 .

[0060] The two clamping arms 12 are disposed at one end of the moving rod 11 . In addition, the two clamping arms 12 extend out of one end of the guide member 3 in the longitudinal direction.

[0061] The two clamping arms 12 are arranged at intervals along the first direction, and the length direction of the clamping arms 12 extends vertically. The interval between the two clamping arms 12 is used for two objects 100 to be fixed to pass through, and the peripheral wall of the clamping arm 12 can abut against the outer side of the object 100 to be fixed. The first direction is perpendicular to both the longitudinal direction and the vertical direction. For the convenience of description, the first direction is defined as the lateral direction. The outer side here refers to the direction away from the center of the guide member 3, and the direction toward the center of the guide member 3 is defined as the inner side, and the same below.

[0062] In this embodiment, the two clamping arms 12 are connected to the moving rod 11 through a support rod 13 respectively. The support rod 13 and the moving rod 11 are in the same plane.

The support end is fixedly connected to the moving rod 11, and there is an angle between the support ends of the two support rods 13, and they are Y-shaped after being connected to the moving rod 11. The free end is fixedly connected to the clamping arm 12, and the clamping arm 12 and the guide member 3 are located on the same side of the moving rod 11.

[0063] In this embodiment, the cross section of the clamping arm 12 is circular. This design enables the peripheral wall of the clamping arm 12 to abut against two objects to be fixed 100 with different angles, which is convenient and simple to operate, and has high flexibility and versatility.

[0064] The adjusting member 4 is movably disposed on the guiding member 3 . Furthermore, the adjusting member 4 and the moving rod 11 are vertically spaced apart to avoid interference between the adjusting member 4 and the moving rod 11 when the adjusting member 4 and the moving rod 11 move relative to the guiding member 3 .

[0065] Figure 3 Schematic diagram of the local structure of the adjusting member 4 in this embodiment.

[0066] refer to Figure 3 The adjusting member 4 includes an adjusting block 41 and a locking member 42 .

[0067] The adjusting block 41 is slidably matched with the guide member 3 and can move along the guide member 3. Specifically, the adjusting block 41 is sleeved on the guide member 3, and the adjusting block 41 is located at one end of the guide member 3 in the longitudinal direction close to the clamping arm 12.

[0068] The locking member 42 is movably connected to the adjusting block 41 and is disposed on the adjusting block 41, and can move relative to the adjusting block 41 to approach and abut against the guide member 3, or to move away from the guide member 3. Specifically, the locking member 42 is disposed at one end of the adjusting block 41 in the lateral direction.

[0069] In this embodiment, the locking member 42 includes a locking plate 421 and a first elastic member 422 .

[0070] The locking plate 421 is at least partially located between the adjusting block 41 and the guide member 3 in the transverse direction. In addition, the locking plate 421 is rotatably connected to the adjusting block 41.

[0071] In this embodiment, the locking plate 421 includes a rotating portion 4211 and a pressing portion 4212 and a locking portion 4213 disposed at opposite ends of the rotating portion 4211 in the longitudinal direction.

[0072] Specifically, the middle portion of the rotating portion 4211 in the longitudinal direction is rotatably connected to the adjusting block 41 via a rotating shaft 423. The rotating shaft 423 extends in the vertical direction.

[0073] The pressing portion 4212 extends in the transverse direction and penetrates the adjusting block 41, one transverse end of which is fixedly connected to the rotating portion 4211, and the other end of which protrudes outward in the transverse direction from the adjusting block 41. Preferably, the connection between the pressing portion 4212 and the rotating portion 4211 is chamfered.

[0074] The locking portion 4213 protrudes from the rotating portion 4211 in a lateral direction and in a direction toward the guide member 3. Preferably, the angle between the locking portion 4213 and the rotating portion 4211 is an obtuse angle.

[0075] The first elastic member 422 is disposed in the adjusting block 41 and its axial direction extends in the transverse direction. When the first elastic member 422 is in a naturally retracted state, the opposite ends of the first elastic member 422 abut against one longitudinal end of the locking plate 421 and the adjusting block 41 respectively.

[0076] In the present embodiment, the locking member 42 further includes a limiting shaft 424. The limiting shaft 424 is provided through the adjusting block 41 and extends into the first elastic member 422, and the limiting shaft 424 is connected and fixed to the adjusting block 41, and is used to limit the first elastic member 422 to the adjusting block 41. Specifically, the limiting shaft 424 includes a main body and a limiting body. The main body is provided through the adjusting block 41 and extends into the first elastic member 422, and the main body is screwed to the adjusting block 41. The limiting body is located at one end of the main body, and the limiting body extends outwardly from the main body in the circumferential direction. At this time, when the first elastic member 422 is in a naturally telescopic state, the opposite ends of the first elastic member 422 are respectively in contact with one end of the locking plate 421 in the longitudinal direction and the limiting body.

[0077] In other embodiments, a limiting groove may be provided inside one lateral end of the adjusting block 41, with the opening direction of the limiting groove facing the guide member 3, for limiting the installation of the first elastic member 422. At this time, when the first elastic member 422 is in a naturally retracted state, one end of the first elastic member 422 abuts against or is fixedly connected to the side wall of the limiting groove away from the guide member 3 in the lateral direction, and the other end extends out of the limiting groove and abuts against or is fixedly connected to the locking plate 421.

[0078] Furthermore, a locking groove 31 is provided on the guide member 3, which is used to cooperate with the locking member 42 to limit the movement of the adjustment block 41. Specifically, the side wall of the guide member 3 facing the locking plate 421 includes a plurality of first wave crests 32 and a plurality of first wave valleys 33, and the first wave crests 32 and the first wave valleys 33 are connected in sequence, wherein a locking groove 31 is formed between adjacent first wave crests 32 and first wave valleys 33. Preferably, the side walls of the first wave crests 32 and the first wave valleys 33 are inclined, and the inclination angle is consistent with the angle between the locking portion 4213 and the rotating portion 4211, so as to improve the locking effect of the locking member 42.

[0079] The working principle of the locking member 42 is as follows: by pressing the pressing portion 4212 of the locking plate 421, the locking plate 421 can be moved toward the guide member 3 to drive the rotating portion 4211 to rotate, and drive the locking portion 4213 to move in a direction away from the guide member 3 to exit the locking groove 31, thereby unlocking the adjustment block 41 and allowing the adjustment block 41 to move along the guide member 3. During the movement of the rotating portion 4211, the first elastic member 422 is compressed. When the adjustment block 41 moves to the desired position, the pressing portion 4212 is released, the first elastic member 422 restores the natural telescopic state and releases the elastic potential energy. Under the action of the elastic force of the first elastic member 422, the rotating portion 4211 rotates, driving the locking portion to move closer to the guide member 3, and extending into the locking groove 31 and being able to be pressed against the locking groove 31, thereby locking the adjustment block 41 and limiting the movement of the adjustment block 41.

[0080] Furthermore, in this embodiment, a scale 37 is provided on the guide member 3, so as to move the adjustment member 4 to a desired position according to the scale 37. Specifically, the scale 37 is provided on the side of the guide member 3 that is vertically away from the moving rod 11. A display port 411 is correspondingly provided on the side of the adjustment block 41 that is vertically away from the moving rod 11, for exposing part of the scale value of the scale 37 on the guide member 3 for viewing. In addition, a pointer is provided on the adjustment block 41 at one side wall of the display port 411 in the horizontal direction, and the pointer extends in the horizontal direction to indicate one of the scale values ​​of the scale 37.

[0081] Continue to refer Figure 1 and Figure 2 The abutting member 2 includes two abutting arms 21. The two abutting arms 21 are arranged one-to-one with the clamping arms 12, and there is a gap between the abutting arms 21 and the corresponding clamping arms 12 to form an accommodation space for accommodating the object to be fixed 100. The abutting arms 21 can abut against the inner side of the object to be fixed 100, and the clamping arms 12 can abut against the outer side of the object to be fixed 100.

[0082] One end of the two supporting arms 21 is rotatably connected, and the other end is rotatably connected to the adjusting member 4, and can move laterally along the movement of the adjusting member 4 along the guide member 3, thereby realizing the adjustable angle between the two supporting arms 21, and cooperating with the clamping arm 12, it can flexibly adapt to clamping two objects to be fixed 100 with different angles, and is easy to operate, highly versatile, and has a wide range of usage scenarios. At this time, the scale value of the scale 37 described above is the value of the angle between the two supporting arms 21.

[0083] In this embodiment, the two abutting arms 21 are rotatably connected via a first connecting shaft 22. The two abutting arms 21 are rotatably connected to the adjusting member 4 via a second connecting shaft 23. In addition, the first connecting shaft 22 and the clamping arm 12 are located on the same side of the length direction of the guide member 3, and the first connecting shaft 22 is fixedly connected to the end of the length direction of the guide member 3. The axis of the first connecting shaft 22 and the axis of the second connecting shaft 23 both extend vertically.

[0084] In this embodiment, the abutting member 2 further includes two connecting rods 24, which are rotatably connected to the ends of the two abutting arms 21 close to the adjusting member 4 in a one-to-one correspondence, and the connecting rods 24 are rotatably connected to the transverse ends of the adjusting member 4 to achieve the rotatable connection between the abutting arms 21 and the adjusting member 4. Specifically, the abutting arms 21 and the connecting rods 24 are rotatably connected via the second connecting shaft 23, and the connecting rods 24 are rotatably connected to the transverse ends of the adjusting block 41 via the pins.

[0085] When in use, the connecting rod 24 can rotate relative to the adjusting block 41 as the adjusting block 41 moves along the guide member 3, thereby driving the supporting arm 21 to rotate relative to the corresponding connecting rod 24, thereby causing the two supporting arms 21 to rotate, so as to achieve adjustable angle between the two supporting arms 21.

[0086] refer to Figure 1 and Figure 2 The clamp includes a jacking assembly 5, which is used to achieve a movable connection between the clamping member 1 and the guide member 3, thereby achieving fine adjustment of the position of the clamping member 1.

[0090] The moving rod 11 is connected and fixed to the housing 51, and can move relative to the guide member 3. Specifically, the mounting block 6 is fixedly connected to the surface of the housing 51 vertically away from the guide member 3. Since the moving rod 11 can be fixedly connected to the mounting block 6 by the fastener 7, the connection and fixation of the moving rod 11 and the housing 51 can be achieved, so that the moving rod 11 can move along the guide member 3 with the housing 51, thereby achieving fine adjustment of the clamping arm 12.

[0091] The moving member 52 is rotatably connected to the housing 51 , and the moving member 52 can rotate to drive the housing 51 to move relative to the guide member 3 .

[0092] In this embodiment, the moving member 52 includes a handle 521 , a connecting plate 522 and a second elastic member 523 .

[0093] The handle 521 has a connecting end and a pressing end. The rotating end extends into the housing 51 and is rotatably connected to the housing 51. Specifically, the rotating end is rotatably connected to the housing 51 via a rotating shaft 524. The axis of the rotating shaft 524 extends vertically. In addition, the connection between the rotating shaft 524 and the rotating end is located at an end of the rotating end close to the clamping arm 12 in the longitudinal direction, and deviates from the center of the rotating end. The pressing end protrudes out of the housing 51 for the operator to press to drive the rotating end to rotate relative to the housing 51.

[0096] When in use, the pressing end of the handle 521 is pressed to drive the rotating end to rotate relative to the housing 51. At this time, the connecting plate 522 moves along the guide member 3 toward the clamping arm 12 as the rotating end rotates, and compresses the second elastic member 523. After the pressing end of the handle 521 is released, the housing 51 moves along the guide member 3 toward the clamping arm 12 under the action of the elastic potential energy released when the second elastic member 523 restores the natural telescopic state, thereby driving the movement of the moving rod 11 and the clamping arm 12 to adjust the position of the clamping arm 12.

[0097] The jacking assembly 5 includes a check member 53 for limiting the movement of the housing 51 , thereby applying a jacking pressure to the clamping arm 12 to lock the position of the clamping arm 12 .

[0098] In this embodiment, the stopper 53 and the moving member 52 are arranged on opposite sides of the guide member 3 in the transverse direction. In addition, the stopper 53 is movably connected to the housing 51 and can move relative to the housing 51 to approach and abut against the guide member 3, or move away from the guide member 3.

[0099] The anti-return member 53 includes an anti-return plate 531 and a third elastic member 532 .

[0100] The non-return plate 531 is at least partially located between the guide members 3 in the housing 51. The non-return plate 531 is rotatably connected to the housing 51.

[0101] The non-return plate 531 includes a rotating portion 5311 and a protruding portion 5312 and a non-return portion 5313 respectively disposed at two longitudinal ends of the rotating portion 5311 .

[0102] The rotating part 5311 is rotatably connected to the housing 51, and the rotating part 5311 is located inside the housing 51. Specifically, the rotating part 5311 is rotatably connected via a hinge shaft. The axis of the hinge shaft extends vertically. Preferably, the connection between the hinge shaft and the rotating part 5311 is located near one end of the protruding part 5312.

[0103] The protruding portion 5312 protrudes outward from the housing 51. In this embodiment, one end of the protruding portion 5312 away from the rotating portion 5311 is inclined in a lateral direction away from the guide member 3.

[0104] The non-return portion 5313 is located in the housing 51 , and one end of the non-return portion 5313 away from the rotating portion 5311 is inclined in a lateral direction toward the guide member 3 for contacting the guide member 3 .

[0105] The third elastic member 532 is disposed in the housing 51, and the third elastic member 532 extends in the lateral direction. Furthermore, when the third elastic member 532 is in a naturally telescopic state, the axial ends of the third elastic member 532 respectively abut against the portion of the check plate 531 located in the housing 51 and the side wall of the housing 51. Specifically, when the third elastic member 532 is in a naturally telescopic state, the third elastic member 532 abuts against one end of the rotating portion 5311 close to the check portion 5313.

[0106] In the present embodiment, the check member 53 further includes a positioning shaft 533. The positioning shaft 533 is provided on the shell 51 and extends into the third elastic member 532, and the positioning shaft 533 is connected and fixed to the shell 51, and is used to position the third elastic member 532 on the shell 51. Specifically, the positioning shaft 533 includes a main body and a positioning body. The main body is provided on the shell 51 and extends into the third elastic member 532, and the main body is screwed to the shell 51. The positioning body is located at one end of the main body, and the positioning body extends outwardly from the main body in the circumferential direction. At this time, when the third elastic member 532 is in a naturally telescopic state, the opposite ends of the third elastic member 532 are respectively in contact with the side of the rotating portion 5311 that is laterally away from the guide member 3 and the positioning body.

[0107] In other embodiments, the third elastic member 532 may be directly fixedly connected to or abutted between the side wall of the housing 51 and the rotating portion 5311 to limit the third elastic member 532 in the housing 51 .

[0108] Furthermore, a slot 34 is provided on the guide member 3 for cooperating with the non-return member 53 to limit the movement of the housing 51. Specifically, the side wall of the guide member 3 facing the non-return plate 531 includes a plurality of second wave crests 35 and a plurality of second wave valleys 36, and the second wave crests 35 and the second wave valleys 36 are sequentially connected, wherein a slot 34 is formed between adjacent second wave crests 35 and second wave valleys 36. Preferably, the side walls of the second wave crests 35 and the second wave valleys 36 are inclined, and the inclination angle is consistent with the angle between the non-return portion 5313 and the rotating portion 5311, so as to improve the locking effect of the non-return member 53.

[0109] The working principle of the above-mentioned check member 53 is as follows: by pressing the protruding portion 5312, it can be moved toward the guide member 3, so as to drive the rotating portion 5311 to rotate, and drive the check member 5313 to move in the direction away from the guide member 3 to exit the slot 34, so as to unlock the housing 51, so that the housing 51 can move along the guide member 3, and then realize the movement of the moving rod 11 and the clamping arm 12. During the movement of the rotating portion 5311, the third elastic member 532 is compressed. After the clamping arm 12 moves to the desired position, the protruding portion 5312 is released, and under the action of the third elastic member 532 restoring the natural telescopic state and releasing the elastic potential energy, the rotating portion 5311 rotates, and drives the check member 5313 to move close to the guide member 3, and extends into the slot 34 and can be pressed against the slot 34, so as to realize the locking of the housing 51, and limit the movement of the housing 51, so as to realize the pushing action of the pushing assembly 5 on the clamping arm 12.

[0110] Figure 5 is a schematic diagram of one direction of the clamp in the working state in this embodiment, Figure 6 FIG. 2 is a schematic diagram showing the clamp in the working state in another direction in this embodiment.

[0111] refer to Figure 5-6 , the working principle of the above fixture is as follows:

[0112] The degree of the angle required to be formed between the two objects to be fixed 100 is used as the preset angle value.

[0113] First, by pressing the pressing portion 4212 of the locking plate 421 of the locking member 42, the locking portion 4213 of the locking plate 421 then exits the locking groove 31 on the guide member 3 to unlock the adjusting block 41. Then, the adjusting block 41 is moved according to the preset angle value to adjust the angle between the two abutting arms 21. When the scale value of the scale 37 indicated by the pointer on the adjusting block 41 is the same as the preset angle value by moving the adjusting block 41, the pressing portion 4212 of the locking plate 421 is released, and under the action of the first elastic member 422 restoring the natural telescopic state and releasing the elastic potential energy, the rotating portion 4211 of the locking plate 421 rotates to drive the locking portion to move close to the guide member 3, and extend into the locking groove 31 and can be pressed against the locking groove 31, so as to achieve the locking of the adjusting block 41, so as to achieve the purpose of fixing the angle between the two abutting arms 21.

[0114] Secondly, the fastener 7 is rotated to withdraw from the mounting block 6 and the moving rod 11 to release the restriction on the moving rod 11. Then, according to the thickness or spacing of the object 100 to be fixed, the moving rod 11 is slid relative to the mounting block 6, and the clamping arm 12 moves with the movement of the moving rod 11, thereby adjusting the minimum distance between the clamping arm 12 and the corresponding abutting arm 21. When the minimum distance between the clamping arm 12 and the corresponding abutting arm 21 is slightly larger than the thickness or spacing of the object 100 to be fixed, the fastener 7 is inserted into the mounting block 6 and the moving rod 11 to connect and fix the moving rod 11 and the mounting block 6, restrict the movement of the moving rod 11, and fix the position of the clamping arm 12.

[0115] The objects to be fixed 100 are placed at an angle, and then the accommodation spaces formed by the supporting arms 21 and the corresponding clamping arms 12 are aligned with the objects to be fixed 100 one by one, so that the two objects to be fixed 100 are accommodated in the two accommodation spaces one by one.

[0116] By pressing the protruding portion 5312 of the check plate 531 of the check member 53, the check portion 5313 of the check plate 531 moves to exit the slot 34 on the guide member 3, thereby unlocking the housing 51. Then, by pressing and releasing the handle 521 of the moving member 52, the housing 51 moves along the guide member 3 under the action of the elastic potential energy released when the second elastic member 523 returns to the natural telescopic state, thereby fine-tuning the position of the clamping arm 12. Until the peripheral wall of the clamping arm 12 abuts against the outer side of the object 100 to be fixed and the abutting arm 21 abuts against the inner side of the object 100 to be fixed, the protruding portion 5312 of the non-return plate 531 is released, and under the action of the elastic potential energy released by the third elastic member 532 restoring the natural telescopic state, the rotating portion 5311 rotates, driving the non-return portion 5313 to move close to the guide member 3, and extend into the slot 34 and can be pressed against the slot 34 to achieve locking of the shell 51, thereby limiting the movement of the clamping arm 12, and temporarily fixing the object 100 to be fixed.

[0117] After the final fixation or welding of the object 100 to be fixed is completed, the housing 51 is unlocked by pressing the protruding portion 5312 of the check plate 531, and the pushing action on the clamping arm 12 is cancelled, so that the clamp can be separated from the object 100 to be removed.

[0118] It can be seen from the above technical solution that the utility model has at least the following advantages and positive effects:

[0119] In the present application, the clamping arm of the clamping member cooperates with the supporting arm of the supporting member to clamp two objects to be fixed, so as to facilitate subsequent welding and other operations between the two objects to be fixed. In addition, by moving the adjusting member along the guide member, the two supporting arms can be driven to move respectively along the first direction to adjust the angle between the two adjusting arms, so as to flexibly adapt to the support of two objects to be fixed with different angles. The operation is convenient and simple, the versatility is high, and the application scenarios are wide.
