Description

Technical Field

[0001] This utility model relates to the field of stage lighting accessories technology, and in particular to a hook that is easy to install and remove. Background Technology

[0002] To enhance the performance effect, existing stages are equipped with a variety of lighting fixtures, such as various cutting lights, beam lights, color-changing lights, strobe lights, LED strip lights, and laser lights. Especially for mobile performances, where stages are temporary structures that need to be dismantled after the performance, a large number of lighting fixtures need to be installed and dismantled, posing a challenge to stage setup personnel. Most existing lighting fixtures used for mobile performances are equipped with folding hooks, achieving the effect of saving space and reducing the time spent on installation and dismantling.

[0003] Patent CN207035009U discloses an inward-flipping, non-disassembly folding lamp hook, which is a common folding lamp hook structure in the prior art. Figure 1 This illustration schematically demonstrates the practical application of the patented technology. (Refer to...) Figure 1 As shown, in its actual products, taking a steel pipe with a diameter of 40-50mm as an example, Figure 1 The left-middle figure shows that when the opening is at its maximum, the distance A between the movable pressure plate and the screw hinge point is 42mm. Figure 1 The diagram on the right shows that when clamping a 40mm diameter steel pipe, the distance A1 between the movable pressure plate and the screw hinge point is 22mm. Therefore, the required travel distance of the handle to clamp a 40mm diameter steel pipe is 42 - 22 = 20mm. In this type of lamp hook structure, the commonly used screw thread is M10, with a standard pitch of 1.5mm. This means that to clamp a 40mm diameter steel pipe, the handle needs to be turned more than 13 times (20 / 1.5 > 13). Assuming each lamp fixture requires two lamp hooks, installing one lamp on the lamp holder would require turning the handle more than 26 times, which is extremely time-consuming and labor-intensive.

[0004] At the same time, refer to Figure 2 As shown, when this type of lamp hook is used in actual use, when the lamp is hung horizontally, due to the special structure of the movable pressure plate, when the lamp rotates and swings, the movable pressure plate will undergo slight elastic deformation due to the pressure of the handle. This can easily cause the friction force of clamping the steel pipe to fluctuate, which can easily lead to the lamp slowly rotating and slipping off the steel pipe.

[0005] Additionally, refer to Figure 3As shown, due to the limitations of its structural principle, this type of lamp hook is difficult to reduce in size. Meanwhile, the number of lights used in performance venues is increasing, which makes it easy for the rotating handle on the lamp hook to interfere with the machine feet, potentially causing the hook body to be unable to fold down and become unusable. Utility Model Content

[0006] This utility model embodiment provides a hook body that is easy to load and unload, in order to solve at least one of the technical problems existing in the prior art lamp hook structure, such as excessively long clamping time, poor clamping reliability when hanging lamps horizontally, and excessively large lamp hook size that easily interferes with machine feet.

[0007] According to one aspect of the present invention, a hook body that is easy to load and unload is provided, characterized in that it comprises:

[0008] The hook body is provided with a fixing plate, and the fixing plate has a first clamping part;

[0009] The movable pressure plate is hinged to the hinge point on the hook body and has a second clamping part. The first clamping part and the second clamping part form a clamping opening.

[0010] The drive assembly includes the drive component and the limiting component.

[0011] The driving member has a pushing part and is configured to move along the axial direction of the limiting member. The pushing part is used to abut against the movable pressure plate to push the movable pressure plate to rotate, so that the second clamping part moves closer to the first clamping part.

[0012] The limiting member is configured to be rotatably mounted on the hook body relative to the hook body, and the rotation direction of the limiting member is configured to allow its axis to rotate toward or away from the hinge point.

[0013] This utility model's easy-to-install hook body directly contacts the movable pressure plate with the driving component of the drive assembly. Simultaneously, the limiting component of the drive assembly can deflect on the hook body, causing the driving component to deflect as well. Therefore, by deflecting the driving component, the contact position between the pushing part on the driving component and the movable pressure plate can be adjusted. When the driving component is deflected to a position closer to the hinge point, the clamping time of the lamp hook is effectively reduced. When the driving component is deflected to a position further away from the hinge point, the user can operate the driving component to clamp more effortlessly. When the driving component is deflected to the middle of the above positions, both time and effort are saved simultaneously. Furthermore, when the limiting member is not rotatable on the hook body, the contact position between the pushing part and the movable pressure plate constantly changes as the pushing part of the driving member pushes the movable pressure plate to rotate, shifting towards the hinge point away from the movable pressure plate. This causes the required stroke of the driving member to continuously increase. The hook body of this invention features a rotatable limiting member, allowing the rotation of the limiting member to maintain a constant contact position between the pushing part and the movable pressure plate, thus keeping the required stroke of the driving member constant and improving clamping efficiency. Compared to existing hook bodies, the hook body of this invention, which is easy to install and remove, has a shorter stroke for the driving member during clamping, effectively improving clamping efficiency. Simultaneously, the hook body of this invention does not rely on the elastic deformation of certain structural components during clamping, thus effectively improving the reliability of clamping when horizontally hanging lamps. Furthermore, the hook body of this utility model can effectively shorten the clamping time, thereby effectively reducing the travel of the drive component, realizing a reduction in the overall size of the hook body, and effectively reducing the occurrence of interference with the machine foot.

[0014] In some embodiments, the movable pressure plate is provided with a slot for abutting against the pushing part.

[0015] Therefore, by setting it up in this way, by providing a slot, the pushing part can cooperate with the slot. When the driving member pushes the movable pressure plate to rotate, the pushing part and the slot are in contact through the cooperation of the pushing part and the slot, so that the driving member can deflect relative to the hook body as the movable pressure plate rotates, keeping the required stroke of the driving member when pushing the movable pressure plate to rotate unchanged.

[0016] In some embodiments, the side of the pushing part that contacts the movable pressure plate is set as an arc surface, and the slot is an arc or hemisphere that matches the shape of the arc surface.

[0017] Therefore, this configuration ensures the proper fit of the contact surfaces between the drive component and the movable pressure plate when they rotate.

[0018] In some embodiments, the side of the slot away from the hinge point has an extension that protrudes outward toward the movable pressure plate.

[0019] Therefore, by using this configuration, the length of the slot can be extended by the extension part, so that the pushing part can still maintain contact and cooperation with the slot even when the rotation angle of the movable pressure plate is too large.

[0020] In some embodiments, the driving member is a driving rod with an external thread, and the limiting member is a threaded connection structure with an internal thread that mates with the external thread on the driving rod.

[0021] Therefore, by using this configuration, the movement of the drive rod can be controlled by a threaded connection, which can effectively control the range of motion and enable self-locking based on the thread.

[0022] In some embodiments, the drive rod is provided with a screw head structure for turning the drive rod.

[0023] Therefore, this design allows the user to more easily operate the drive component by utilizing the screw head structure.

[0024] In some embodiments, a first elastic element is provided between the screw head structure and the threaded connection structure.

[0025] Therefore, by setting it up in this way, the first elastic element can be used to prevent loosening of the fit between the drive element and the threaded connection structure, thereby improving the stability during clamping.

[0026] In some embodiments, the hook body is provided with a central groove, the hinge point is located within the area of ​​the central groove, and the movable pressure plate is located within the central groove.

[0027] Therefore, by setting it up in this way, the movable pressure plate can be placed in the middle groove, and the hook body can be used to protect the hinge position on the movable pressure plate and the structure of the movable pressure plate itself.

[0028] In some embodiments, a second elastic element is further provided between the hook and the movable pressure plate. The second elastic element is used to drive the movable pressure plate to rotate so that the second clamping part moves away from the first clamping part.

[0029] Therefore, by using this configuration, the movable pressure plate can be rotated by the second elastic element, causing the second clamping part to move away from the first clamping part, so that the movable pressure plate is always kept at the maximum range of opening, which is beneficial for clamping.

[0030] In some embodiments, the hook body is further provided with a flip connector and / or mounting holes.

[0031] The flip connector includes at least two legs, each leg having a pivot hole. The pivot holes on each leg are coaxially aligned, and the plane containing the axis of the pivot hole is parallel to the plane containing the axis of the clamping opening.

[0032] The plane containing the axis of the mounting hole is perpendicular to the plane containing the axis of the clamping opening.

[0033] Therefore, with this configuration, the lamp can be installed using the flip connector or mounting hole. At the same time, the axial direction of the pivot hole on the flip connector and the axial direction of the mounting port ensure that when the hook of this utility model is used to hang the lamp horizontally, the drive component and the pushing component further apply force to the movable pressure plate, thereby ensuring the stability of the lamp when it is hung horizontally.

[0054] The present invention will now be described in further detail with reference to the accompanying drawings.

[0055] Figure 4 The schematic diagram illustrates the overall structure of the easy-to-load and detach hook body according to one embodiment of the present invention, with reference to... Figure 4 As shown, the easy-to-load and easy-to-unload hook of this utility model includes a hook body, a fixed pressure plate disposed on the hook body, a movable pressure plate hinged to the hook body, and a drive assembly movably disposed on the hook body.

[0056] Specifically, the fixed pressure plate 2 has a first clamping part 21, and the movable pressure plate 3 has a second clamping part 31. The first clamping part 21 and the second clamping part 31 are arranged opposite to each other to form a clamping opening 12. The fixed pressure plate 2 is disposed on the hook body 1 and is fixedly connected to the hook body 1 by means of detachment or non-detachment, so that the fixed pressure plate 2 cannot move relative to the hook body 1, serving as the fixed end of the formed clamping opening 12. The movable pressure plate 3 is hinged to the hinge point 11 of the hook body 1, so that the movable pressure plate 3 can rotate around the hinge point 11, serving as the movable end of the formed clamping opening 12. In addition, in some possible embodiments, the hook body 1 may also be provided with an intermediate groove 13, the hinge point 11 is located within the area of ​​the intermediate groove 13, and the movable pressure plate 3 is located within the intermediate groove 13, thereby using the hook body 1 to protect the structure of the movable pressure plate 3. For example, refer to... Figure 5 and Figure 6 As shown, in Figure 5 and Figure 6 In the illustrated embodiment, the fixed pressure plate 2 is integrally formed and fixedly mounted on the hook body 1. The hook body 1 has a central groove 13, and a hinge point 11 is located within the area of ​​the central groove 13, including a pin fixing hole 111 penetrating the hook body 1 and a pin 112 passing through the pin fixing hole 111. The pin 112 can be a flexible cylindrical pin, a solid pin, or other types of pins that meet the requirements. The movable pressure plate 3 is disposed within the central groove 13, and its right end is hinged to the pin 112 to achieve hinge at the hinge point 11 on the hook body 1. By placing the movable pressure plate 3 within the central groove 13, the hinge position of the movable pressure plate 3 can be protected, and the structure of the movable pressure plate 3 can be protected. (Refer to...) Figure 6 As shown, it can also be further configured so that only the second clamping part 31 of the movable pressure plate 3 is exposed, so as to effectively avoid affecting the rotation of the movable pressure plate 3.

[0057] Regarding the first clamping part 21 and the second clamping part 31, the first clamping part 21 can be a clamping structure provided on the fixed pressure plate 2, such as an arc-shaped clamping surface. Similarly, the second clamping part 31 can be a clamping structure provided on the movable pressure plate 3, such as an arc-shaped clamping surface. For example, referring to... Figure 5 As shown, in Figure 5 In the illustrated embodiment, to facilitate clamping the steel pipe, both the fixed pressure plate 2 and the movable pressure plate 3 are arc-shaped. The first clamping part 21 on the fixed pressure plate 2 is located on the inner side of the arc, and the second clamping part 31 on the movable pressure plate 3 is also located on the inner side of the arc. (Refer to...) Figure 5As shown, the fixed pressure plate 2 is shaped like a "V" with an arc forming at its intermediate transition position, so that the first clamping part 21 has two clamping surfaces, corresponding to the X and Y surfaces respectively. The second clamping part 31 on the movable pressure plate 3 has one clamping surface, corresponding to the Z surface. The X and Y surfaces on the fixed pressure plate 2 and the Z surface on the movable pressure plate 3 together form a "C"-shaped shape, and the space surrounding it forms the clamping opening 12. In this embodiment, the clamping center of the clamping opening 12 is the center, and the included angle between the three clamping surfaces is no greater than 180°, thereby ensuring the stability of the clamping opening 12 during clamping. The two clamping surfaces corresponding to the first clamping part 21 on the fixed pressure plate 2 and the one clamping surface corresponding to the second clamping part 31 on the movable pressure plate 3 can be provided with anti-slip structures to improve the friction during clamping, such as anti-slip textures or anti-slip rubber layers on these clamping surfaces, etc., which will not be listed in detail here.

[0058] The drive assembly 4 is a user-operated drive unit used to move the movable pressure plate 3. Specifically, the drive assembly 4 includes a drive member and a limiting member. The limiting member is rotatably mounted on the hook body 1 relative to the hook body 1, and its rotation direction is configured to allow its axis to rotate towards or away from the hinge point 11. The drive member is movable along the axis of the limiting member and has a pushing part 44. The pushing part 44 abuts against the movable pressure plate 3, thereby pushing the movable pressure plate 3 to rotate, narrowing the clamping opening 12, and thus clamping objects such as steel pipes. The drive assembly 4 can be a structure commonly used in the art, such as a screw assembly or a pushing rod assembly. When the drive assembly 4 uses a screw assembly, the self-locking property of the thread can be used for locking. If the drive assembly 4 uses a pushing rod assembly, a locking position of the drive assembly 4 needs to be set separately to lock it in place so that the clamping opening 12 remains clamped. (Refer to...) Figure 5 and Figure 6 As shown, in the embodiment where the drive assembly 4 adopts a screw assembly, the drive member is a drive rod 41, the pushing part 44 is provided at the first end of the drive rod 41, and the drive rod 41 is provided with an external thread. The limiting member is a threaded connection structure 42 rotatably provided on the hook body 1. The threaded connection structure 42 has an internal thread that mates with the external thread on the drive rod 41. Thus, by cooperating with the drive rod 41 through the threaded connection structure 42, the drive rod 41 can move back and forth along the axis of the threaded hole of the threaded connection structure 42 to push the movable pressure plate 3 to move.

[0059] In some possible implementations, since the threaded connection structure 42 is rotatably mounted on the hook body 1, it can be configured to be detachably mounted on the hook body 1. Specifically, the hook body 1 is provided with a mounting groove 14, and the threaded connection structure 42 is detachably mounted on the mounting groove 14. The mounting groove 14 can be a through groove penetrating the hook body 1, or it can only penetrate to one side of the hook body 1 and connect to the intermediate groove 13. (Refer to...) Figure 6 As shown, the mounting groove 14 can be circular, and the threaded connection structure 42 can be a cylindrical nut, thus adapting to the shape of the circular mounting groove 14. This arrangement allows the axis of the threaded hole of the threaded connection structure 42 to rotate towards or away from the hinge point 11, thereby allowing the position of the pushing part 44 of the drive rod 41 to be adjusted by rotating the threaded connection structure 42.

[0060] For the drive rod 41, the pushing part 44 on the drive rod 41 is the part for contacting the movable pressure plate 3. For example, the pushing part 44 can refer to a structure specifically provided on the drive rod 41, such as a boss provided on the drive rod 41, or it can refer to the contact surface on the drive rod 41 that will contact the movable pressure plate 3 (i.e., there is no special structure designed for the position for contacting the movable pressure plate 3). For example, refer to Figure 5 and Figure 6 As shown, in Figure 5 and Figure 6 In the illustrated embodiment, the pressing part 44 is specifically configured as an arc-shaped surface at the first end of the drive rod 41. Correspondingly, in some embodiments, a slot 32 for abutting against the pressing part 44 can also be provided on the movable pressure plate 3 at the position where it contacts the pressing part 44. The shape of the slot 32 can be configured to match the shape of the pressing part 44, for example, it can be configured as an arc or a hemispherical shape. In addition, an extension 34 can be protruding outward from the side of the slot 32 away from the hinge point 11 towards the outside of the movable pressure plate 3 to delay the slot 32. With this design, the length of the slot 32 can be extended by the extension 34, so that even when the rotation angle of the movable pressure plate 3 is too large, the pressing part 44 can still maintain contact with the slot 32. Combined with the threaded connection structure 42 rotatably provided on the hook body 1, it can be ensured that the angle of rotation of the movable pressure plate 3 driven by a unit stroke remains unchanged.

[0061] In some possible embodiments, the contact point between the pressing part 44 and the movable pressure plate 3 can be set near the hinge point 11. This arrangement significantly reduces the travel required for the pressing part 44 to rotate when the drive rod 41 pushes the movable pressure plate 3, thereby reducing the travel of the drive assembly 4 and decreasing the overall clamping time. In other possible embodiments, this position can be set at the center of the movable pressure plate 3. This arrangement ensures an effective reduction in the travel required for the pressing part 44 to rotate when the drive rod 41 pushes the movable pressure plate 3, while also making it easier for the user to operate the drive rod 41 for clamping, thus simultaneously saving time and effort. For example, refer to... Figure 5 As shown, in Figure 5 In the embodiment shown, the pushing part 44 of the drive rod 41 is located in the middle of the movable pressure plate 3, that is... Figure 5 The center is located near the middle of the hook body 1, which allows the whole unit to save time and effort during use.

[0062] In some possible embodiments, the drive rod 41 may also be provided with a screw head structure 45 for rotating the drive rod 41. The screw head structure 45 makes it easier and less strenuous for the user to rotate the drive rod 41. In other possible embodiments, a first elastic member 43 is provided between the screw head structure 45 and the threaded connection structure 42. The first elastic member 43 can prevent loosening of the fit between the drive rod 41 and the threaded connection structure 42, thereby improving stability during clamping. For example, refer to Figure 6 As shown, in Figure 6 In the embodiment shown, the first elastic element 43 is a spring, and the pushing part 44 of the drive rod 41 passes through the first elastic element 43 and the threaded connection structure 42 in sequence and abuts against the movable pressure plate 3. Meanwhile, in Figure 6 In the illustrated embodiment, the screw-in head structure 45 is configured as a movable handle passing through the drive rod 41 in a direction perpendicular to the axis of the drive rod 41, thereby adapting to various narrow operating spaces and facilitating the user to screw the drive rod 41. In some other possible embodiments, the screw-in head structure 45 may also be configured as a "T"-shaped fixed handle fixed to the end of the drive rod 41 away from the pushing part 44.

[0063] In some possible implementations, the easy-to-load hook of this invention can also have a second elastic element 5 provided between the hook body 1 and the movable pressure plate 3. The second elastic element 5 is used to drive the movable pressure plate 3 to rotate, so that the second clamping part 31 moves away from the first clamping part 21, and the clamping opening 12 maintains the maximum opening angle. The second elastic element 5 can be a tension spring or a torsion spring, or other commonly used elastic element structures. The first end of the second elastic element 5 is fixed to the hook body 1, and the second end is fixed to the movable pressure plate 3. Specifically, the movable pressure plate 3 can be provided with a connecting structure for connecting to the second elastic element 5, and the hook body 1 can also be provided with a connecting structure for connecting to the second elastic element 5. These connecting structures can be configured by providing protrusions to hook the second elastic element 5, or by providing recesses to hook the second elastic element 5, or by providing screws 51, hooks, or other structures on their surfaces to hook the second elastic element 5. Correspondingly, the second elastic element 5 can be provided with hooking holes. For example, refer to Figure 6 As shown, in Figure 6 In the illustrated embodiment, the second elastic element 5 is a tension spring with a circular hole at its first end and a square hole at its second end. A protrusion and an elastic element fixing groove 33 are provided on the movable pressure plate 3 at the end away from the second clamping part 31. A screw 51 is threaded onto the hook body 1 near the fixed pressure plate 2. The circular hole of the tension spring hooks onto the screw 51, and the square hole hooks onto the elastic element fixing groove 33, thereby pulling the end of the movable pressure plate 3 away from the second clamping part 31 towards the fixed pressure plate 2, causing the movable pressure plate 3 to rotate, thus moving the second clamping part 31 away from the first clamping part 21, and keeping the clamping opening 12 at its maximum opening angle.

[0064] In some possible embodiments, the hook body 1 may also be provided with a flip connector 61 or mounting hole 62 for connecting to the lamp base. When the hook body 1 is provided with a flip connector 61, the flip connector 61 includes at least two legs 611, each leg 611 having a pivot hole 612. The pivot holes 612 on each leg 611 are coaxially arranged, and the plane containing the axis of the pivot hole 612 is parallel to the plane containing the axis of the clamping opening 13. This arrangement ensures that when the hook body 1 of this invention is used to hang the lamp horizontally, the driving assembly 4 and the pushing member 5 further apply force to the movable pressure plate 3, thereby ensuring the stability of the lamp when it is hung horizontally. When the hook body 1 is provided with a mounting hole 62, the mounting hole 62 can be used to install various detachable flip connection structures. Specifically, the plane containing the axis of the mounting hole 62 is perpendicular to the plane containing the axis of the clamping opening 13, thereby ensuring that when the hook 1 of this utility model is used to hang the lamp horizontally, the driving component 4 and the pushing component 5 further apply force to the movable pressure plate 3, thus ensuring the stability when the lamp is hung horizontally. For example, refer to... Figure 5 As shown, Figure 5 A hook body 1 with a flip connector 61 is shown. The hook body 1 extends away from the fixed pressure plate 2 at one end, and the flip connector 61 is disposed in this extended portion. The flip connector 61 includes two legs 611, each with a pivot hole 612. The two pivot holes 612 are coaxially arranged, and the plane containing their axes is parallel to the plane containing the axis of the clamping opening 13. (Refer to...) Figures 7 to 9 As shown, it illustrates the structure of a hook body 1 with a mounting hole 62. The end of the hook body 1 extends away from the fixed pressure plate 2, and the mounting hole 62 is provided in the extended part. The plane containing the axis of the mounting hole 62 is perpendicular to the plane containing the axis of the clamping port 13.

[0065] Figures 10 to 12 The diagram schematically illustrates the structure of the hook 1 with different flip-connection structures mounted on the mounting hole 62, for reference. Figure 10 As shown, the flip-connecting structure includes a first flip-connector 63, which is a U-shaped piece with a flat bottom and symmetrical and parallel sides. It includes two connecting edges 631 and a mounting base 632. The two connecting edges 631 are arranged parallel to each other and spaced apart. The two ends of the mounting base 632 are connected to the same side ends of the two connecting edges 631, respectively. The ends of the two connecting edges 631 furthest from the mounting base 632 are semi-circular. Each connecting edge 631 has a first pivot hole 633, which is concentric with the semi-circle. A through hole is provided at the center of the mounting base 632. A bolt passes through the through hole, an elastic washer, and the mounting hole 62 on the hook body 1 in sequence, and is then tightened to a mounting nut. Under strong force, the first flip-connector 63 can rotate around the center of the bolt.

[0066] Reference Figure 11 As shown, the flip-connecting structure includes a second flip-connector 64, which is an integrally cast part. It includes two connecting legs 641 and studs positioned above the two connecting legs 641. The two connecting legs 641 are provided with second pivot holes 642, which are coaxial. The stud passes sequentially through an elastic washer, a mounting hole 62 on the hook body 1, and is then securely connected to a mounting nut. Under strong force, the second flip-connector 64 can rotate around the center of the stud.

[0067] Reference Figure 12 As shown, the flip connection structure includes a hexagonal bolt 65, which passes through the mounting hole 62 on the hook body 1. A flat washer and a spring washer are then placed on top of each other, and the mounting nut 66 is screwed on. The mounting nut 66 can be a wing nut or a hexagonal nut.

[0068] The hook body of this utility model, which is easy to load and unload, directly contacts the driving component of the driving assembly 4 with the movable pressure plate 3. At the same time, the limiting component of the driving assembly 4 can deflect on the hook body 1, so as to drive the driving component to deflect together. Therefore, by deflecting the driving component, the contact position between the pushing part 44 on the driving component and the movable pressure plate 3 can be adjusted. When the driving component is deflected so that the contact position between its pushing part 44 and the movable pressure plate 3 is adjusted to a position closer to the hinge point 11, the time required for clamping the lamp hook can be effectively reduced. When the driving component is deflected so that the contact position between its pushing part 44 and the movable pressure plate 3 is adjusted to a position further away from the hinge point 11, it is easier for the user to operate the driving component to clamp. When the driving component is deflected so that the contact position between its pushing part 44 and the movable pressure plate 3 is adjusted to the middle of the above positions, both time-saving and labor-saving can be achieved at the same time. Furthermore, when the limiting member is not rotatable on the hook body 1, the contact position between the pushing part 44 and the movable pressure plate 3 will continuously change as the pushing part 44 pushes the movable pressure plate 3 to rotate, and will change towards the hinge point 11 away from the movable pressure plate 3. This causes the required stroke of the driving member to continuously increase. The hook body 1 of this utility model has a limiting member designed to be rotatably mounted on the hook body 1. By utilizing the rotation of the limiting member, the contact position between the pushing part 44 and the movable pressure plate 3 remains unchanged, thereby keeping the required stroke of the driving member constant and improving clamping efficiency. Compared with the hook body 1 of the prior art, the hook body 1 of this utility model has a shorter stroke of the driving member during clamping, which can effectively improve clamping efficiency. At the same time, the hook body 1 of this utility model does not need to rely on the elastic deformation of certain structural components to achieve clamping, thereby effectively improving the reliability of clamping when hanging lamps horizontally. Furthermore, the hook body 1 of this utility model can effectively shorten the clamping time, thereby effectively reducing the travel of the drive component 4, realizing the reduction of the overall size of the hook body 1, and effectively reducing the occurrence of mutual interference with the machine foot.
