Description

Technical Field

[0001] This invention relates to the field of operating tools, and in particular to fastening wrenches for radio frequency connectors. Background Technology

[0002] As electronic devices become increasingly integrated and miniaturized, their internal space is shrinking, leading to a higher density of electrical interfaces. For electrical equipment installed in cabinets, interfaces are densely packed, typically for connecting RF connectors with knurled sleeves. This results in small spacing between the RF connectors, and the connectors often have thick cables at their ends. This dense arrangement of RF connectors on electrical equipment leads to a large accumulation of cables, making it difficult to reach the interfaces for tightening and securing.

[0003] Currently, pliers are typically inserted through the rack window into the cabinet to tighten the RF connector and secure it to the interface. However, the cables on the RF connectors obstruct the pliers' entry into the rack. Furthermore, the densely packed interfaces and their small spacing, combined with the thick jaws of the pliers, only allow for gripping the edge of a single interface. This prevents the pliers from fully clamping and tightening the connector between adjacent interfaces, leading to the connector easily loosening or even detaching from the interface. Summary of the Invention Based on the above analysis, the present invention aims to provide a tightening wrench for radio frequency connectors to solve the problem in the prior art that radio frequency connectors are difficult to clamp and tighten, resulting in loosening or even falling off at the interface.

[0004] The objective of this invention is mainly achieved through the following technical solutions: A tightening wrench for radio frequency connectors includes a clamp body and a clamp jaw connected in sequence. The clamp jaw includes an arc-shaped piece and a connecting block. One end of the connecting block is connected to the clamp body, and the other end is connected to the arc-shaped piece.

[0005] The clamp body includes a second telescopic rod and a second adjustment component. There are two identical second telescopic rods, each equipped with the clamp jaws. The two second telescopic rods are symmetrically arranged and parallel to each other.

[0006] The second telescopic rod includes an adjusting rod, and the second adjusting assembly includes a fixed assembly, a moving assembly, and a third telescopic rod. The fixed assembly is simultaneously fitted onto both adjusting rods, and the moving assembly includes an adjusting block. The moving assembly is simultaneously fitted onto both adjusting rods. The outer wall of the adjusting rod is set as an inclined surface, and the distance between the two adjusting rods can be adjusted by moving the adjusting block on the inclined surface of the adjusting rod.

[0007] The second end of the third telescopic rod is fixedly mounted on the moving assembly. The moving assembly can be moved along the adjusting rod by changing the length of the third telescopic rod. The third telescopic rod is provided with a second spring. When clamping, the moving assembly moves towards the jaws under the action of the second spring. During the movement, the distance between the two second telescopic rods is reduced by the pressure of the adjusting block on the adjusting rod, thereby reducing the distance between the two arc-shaped pieces and increasing the clamping force of the jaws on the RF connector to achieve clamping and fixing.

[0008] The fixing component is provided with a slide rail, and the first end of the third telescopic rod is provided on the slide rail and can move along the slide rail to adjust the maximum distance between the fixing component and the moving component, so that the moving component can move a large distance on the adjusting rod to reduce the distance between the two mounting rods, thereby enabling the two arc-shaped pieces to clamp the smaller RF connector.

[0009] Furthermore, the second telescopic rod includes a second outer sleeve and a second inner rod. One end of the second outer sleeve is connected to the second adjusting assembly, and the other end is provided with a cavity for installing the second inner rod. The second inner rod is movable within the cavity. The two second inner rods are respectively connected to the arc-shaped piece.

[0010] Furthermore, the second outer sleeve includes a main sleeve, the adjusting rod, and a mounting rod connected in sequence. One end of the main sleeve has a cavity to accommodate the second inner rod, and the other end is connected to the adjusting rod. One end of the mounting rod is connected to the adjusting rod, and the other end is used to install the second adjusting assembly.

[0011] Furthermore, the fixing component includes a fixing block and a support frame. The fixing block is a square block with a through hole. Two mounting rods are inserted from the first end of the fixing block and pass through the through hole, so that the mounting rods protrude from the second end of the fixing block. The support frame is disposed at the second end of the fixing block to limit the portion of the mounting rods protruding from the fixing block.

[0012] Furthermore, the support frame includes a fixed rod and a track. The fixed rod is vertically disposed at both ends of the track. One end of the fixed rod is vertically connected to the fixed block, and the other end is connected to the track, so that the track can pass through the through hole port on the fixed block. The mounting rod is disposed on the track and can move along the track.

[0013] Furthermore, the track is a square rod, and the top and bottom ends of the track are provided with third slots. The mounting rod is provided with a limiting component, which engages with the third slot to allow the mounting rod to move along the track.

[0014] Furthermore, the moving component includes a moving block and an adjusting block. The moving block is a square block with a square through hole. Two adjusting rods pass through the through hole on the moving block. The adjusting block is disposed inside the moving block and symmetrically distributed at both ends of the adjusting rods, so that the adjusting rods can move in contact with the adjusting block within the through hole of the moving block.

[0015] Furthermore, multiple third springs are provided between the two second telescopic rods, and the third springs are in a compressed state. The elastic force of the third springs causes the second telescopic rods to press against the adjusting blocks at both ends.

[0016] Furthermore, the third telescopic rod includes a first base, a second base, a third outer sleeve, and a third inner rod. The first base is located at the first end of the third telescopic rod, and the bottom end of the first base has a groove to engage the slide rail. The second base is vertically located at the top end of the moving block. One end of the third outer sleeve is vertically connected to the first base, and the third inner rod is inserted into the cavity at the other end of the third outer sleeve. The third inner rod is vertically connected to the second base.

[0017] Furthermore, the third outer sleeve is also provided with a threaded hole that penetrates the tube wall, and the third adjusting screw is inserted into the threaded hole to press and fix the third inner rod inside the third outer sleeve.

[0018] Compared with the prior art, the present invention can achieve at least one of the following beneficial effects: (1) The fastening wrench for radio frequency connectors of the present invention includes a clamp body comprising a connected clamp shoulder and two clamp arms, such that the clamp shoulder is located between the clamp jaws and the clamp arms, and the clamp shoulder can be opened and closed by the clamp arms, thereby the clamp shoulder controls the opening and closing of the clamp jaws. By controlling the opening and closing of the clamp jaws, radio frequency connectors of different sizes can be clamped and fixed, thus expanding the application range.

[0019] (2) The fastening wrench for radio frequency connectors of the present invention uses a first adjustment component to achieve relative fixation of the jaw and the jaw. The first spring can support part of the clamp head in the first groove and the other part in the insertion tube, thereby achieving relative fixation of the insertion block and the connecting block. Pressing the locking cap can drive the locking pin to press the clamp head and retract it into the first groove. Then, the connecting block moves relative to the insertion block. During the movement, the side wall of the first slot on the connecting block pushes the clamp head back into the first groove, thereby releasing the relative fixation of the insertion block and the connecting block, realizing the disassembly of the jaw, facilitating the replacement of different types of jaws, and expanding the application range.

[0020] In this invention, the above-described technical solutions can be combined with each other to achieve more preferred combinations. Other features and advantages of this invention will be set forth in the following description, and some advantages may become apparent from the specification or be learned by practicing the invention. The objectives and other advantages of this invention can be realized and obtained from the content specifically pointed out in the text and accompanying drawings. Attached Figure Description

Detailed Implementation

[0024] Preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which form part of this application and, together with the embodiments of the present invention, serve to illustrate the principles of the present invention.

[0025] Example 1 This embodiment discloses a tightening wrench for radio frequency connectors, such as... Figure 1 As shown, it includes a clamp body 1 and a clamp jaw 2 connected in sequence. The RF connector is located inside the clamp jaw 2. The clamp body 1 can control the opening and closing of the clamp jaw 2 to clamp and fix the RF connector.

[0026] Specifically, the clamp body 1 includes a connected clamp shoulder 11 and two clamp arms 12, with the clamp shoulder 11 positioned between the clamp jaws 2 and the clamp arms 12. The clamp arms 12 can open and close the clamp shoulder 11, thereby controlling the opening and closing of the clamp jaws 2. By controlling the opening and closing of the clamp jaws 2, RF connectors of different sizes can be clamped and fixed, expanding the application range.

[0027] The jaws 2 include symmetrically distributed arc-shaped pieces 21 and connecting blocks 22. One end of the connecting block 22 is connected to the jaw shoulder 11, and the other end is vertically disposed on the outer side wall of the arc-shaped piece 21, so that the arc-shaped piece 21 is connected to the jaw shoulder 11 through the connecting block 22. Two arc-shaped pieces 21 can be mated to form a cylinder with a through hole. The RF connector is disposed inside the cylinder formed by the arc-shaped pieces 21, and the RF connector is fixed by clamping the two arc-shaped pieces 21.

[0028] To enhance the clamping and fixing of the RF connector, the inner surface of the arc-shaped piece 21 that contacts the RF connector is provided with teeth, which enhance the friction between the clamping jaw 2 and the threaded sleeve of the RF connector.

[0029] See Figure 2 The clamp shoulder 11 includes a rivet 111 and two bent connecting rods 112. The two ends of the connecting rods 112 are connected to the clamp arm 12 and the clamp jaw 2, respectively. The middle part of the connecting rod 112 is provided with a pin hole to fit on the rivet 111 and can rotate around the rivet 111, so that the two connecting rods 112 are cross-overlapping and fitted on the rivet 111. The connected rods 112 are symmetrically distributed after fitting, so that the connected arc-shaped pieces 21 can be symmetrically distributed and docked to clamp the RF connector. The connecting block 22 is provided with a first slot 221 to insert the connecting rod 112, so that one end of the connecting rod 112 is inserted into the first slot 221 of the connecting block 22, and the other end is connected to the clamp arm 12.

[0030] Further, see Figure 2 , Figure 3The first adjusting component 3 is used to fix the relative position of the jaws 11 and 2. The first adjusting component 3 includes a tube 31, a locking cap 32, a locking pin 33, a first spring 34, and a locking head 35. The connecting block 22 has a through hole communicating with the first slot 221. The tube 31 is located at the top of the connecting block 22 and its inner cavity communicates with the through hole on the connecting block 22, so that one end of the locking pin 33 can pass through the tube 31 and the through hole on the connecting block 22 in sequence and extend into the first slot 221. The other end of the locking pin 33 is connected to the locking cap 32, so that the locking cap 32 is located outside the connecting block 22. One end of the connecting rod 112 is provided with a plug 1121 to be inserted into the first slot 221 for connection. The plug 1121 has a first groove with its port facing the locking pin 33. After the plug 1121 is inserted into the first slot 221, the first groove can... Connected to the insertion tube 31, one end of the first spring 34 is located on the bottom surface of the first groove, and the other end is connected to the clamp head 35. The first spring 34 can support the clamp head 35 to extend and retract within the first groove, causing the clamp head 35 to protrude from the port of the first groove and extend into the insertion tube 31, so that part of the clamp head 35 is in the first groove and the other part is in the insertion tube 31, thereby achieving relative fixation between the insertion block 1121 and the connecting block 22. Pressing the locking cap 32 can drive the locking pin 33 to press against the clamp head 35 and retract it into the first groove. Then, the connecting block 22 moves relative to the insertion block 1121. During the movement, the side wall of the first slot 221 on the connecting block 22 pushes the clamp head 35 back into the first groove, thereby releasing the relative fixation between the insertion block 1121 and the connecting block 22, realizing the disassembly of the jaw 2, which facilitates the replacement of different types of jaws 2 and expands the application range.

[0031] To prevent the locking pin 33 from passing through the insertion tube 31 and entering the first groove, the outer diameter of the locking pin 33 is larger than the inner diameter of the port of the first groove. Thus, the locking pin 33 can press the locking head 35 into the first groove completely but will not insert it into the first groove, thereby affecting the unlocking between the connecting block 22 and the insertion block 1121.

[0032] To prevent the locking pin 33 from detaching from the insertion tube 31, a baffle 311 with a through hole can be installed on the insertion tube 31 near the port of the locking cap 32. The locking pin 33 is located in the through hole of the baffle and can move within the through hole. The portion of the locking pin 33 located inside the insertion tube 31 is provided with a boss 331. The boss 331 is arranged around the pin body of the locking pin 33 and its outer diameter is larger than the inner diameter of the through hole of the baffle 311, so that the boss 331 cannot pass through the baffle 311, thereby limiting the locking pin 33 within the insertion tube 31.

[0033] Furthermore, the clamp arm 12 includes a first handle 121 and a first telescopic rod 122 connected in sequence. The first handle 121 is designed as a scissor-like handle for easy use by the operator. The first telescopic rod 122 is a sleeve structure, including a first outer sleeve 1221 and a first inner rod 1222 movably disposed in the cavity of the first outer sleeve. One end of the first outer sleeve 1221 is connected to the first handle 121, and the other end has a cavity with its port facing the clamp jaws 2 for inserting the first inner rod 1222, so that one end of the first inner rod 1222 is inserted into the cavity of the first outer sleeve 1221 and can move within the cavity, while the other end is fixed in the second slot of the connecting rod 112. In order to enable the first inner rod 1222 to move stably within the first outer sleeve 1221, the first inner rod 1222 is designed as a square rod, and the cross-section of the cavity of the first outer sleeve 1221 is also designed as a square, so that the first inner rod 1222 can move in contact with the end face of the cavity.

[0034] In order to adjust the length of the telescopic rod, the wall of the first outer sleeve 1221 is provided with a threaded hole that communicates with the cavity of the tube body to install the first adjusting screw, so that the first adjusting screw can pass through the threaded hole to press and fix the first inner rod 1222 in the cavity.

[0035] Example 2 This embodiment is an alternative design of the clamp body 1 in Embodiment 1.

[0036] See Figure 4 The clamp body 1 includes a second telescopic rod 13 and a second adjustment component 14. One end of the second telescopic rod 13 is connected to the jaws 2, and the other end is connected to the second adjustment component 14 so that the jaws 2 can be opened and closed by the second telescopic rod 13.

[0037] Specifically, there are two identical second telescopic rods 13, each equipped with a clamping jaw 2. The two second telescopic rods 13 are symmetrically arranged and parallel, including a second outer sleeve 131 and a second inner rod 132. One end of the second outer sleeve 131 is connected to the second adjustment assembly 14, and the other end has a cavity for installing the second inner rod 132 and allowing the second inner rod 132 to move within the cavity. The two second inner rods 132 are respectively connected to arc-shaped pieces 21, so that the two arc-shaped pieces 21 are symmetrically arranged and can be mated, thereby allowing the arc-shaped pieces 21 to clamp and fix the RF connector. Similarly, in order to adjust the length of the second telescopic rod 13, the wall of the second outer sleeve 131 is provided with a threaded hole communicating with the cavity of the second outer sleeve 131 for installing a second adjusting screw 133, so that the second adjusting screw 133 can pass through the threaded hole to press and fix the second inner rod 132 within the cavity.

[0038] See Figure 5The second outer sleeve 131 includes a main sleeve 1311, an adjusting rod 1312, and a mounting rod 1313 connected in sequence. One end of the main sleeve 1311 has a cavity to accommodate the second inner rod 132, and the other end is connected to the adjusting rod 1312. The outer wall of the adjusting rod 1312 is set as an inclined surface to serve as a slide for the second adjusting assembly 14. The distance between the two second telescopic rods 13 is changed by the movement of the second adjusting assembly 14 on the inclined surface, thereby realizing the adjustment of the distance between the two arc-shaped pieces 21, which facilitates the clamping jaws 2 to clamp and fix RF connectors of different sizes. One end of the mounting rod 1313 is connected to the adjusting rod 1312, so that the adjusting rod 1312 is located between the main sleeve 1311 and the mounting rod 1313, and the other end is used to install the second adjusting assembly 14.

[0039] Specifically, see Figure 6 The second adjustment component 14 is used to adjust the distance between the two second telescopic rods 13, thereby achieving clamping and fixing of the RF connector. The second adjustment component 14 includes a fixed component 141, a movable component 142 and a third telescopic rod 143. The fixed component 141 is simultaneously sleeved on the two mounting rods 1313, and the movable component 142 is simultaneously sleeved on the two adjustment rods 1312. The first end of the third telescopic rod 143 is disposed on the fixed component 141 and can move on the fixed component 141, and the second end is fixedly disposed on the movable component 142. The distance between the fixed component 141 and the movable component 142 can be changed by the third telescopic rod 143.

[0040] Furthermore, the fixing component 141 includes a fixing block 1411 and a support frame 1412. The fixing block 1411 is a square block with a through hole. Two mounting rods 1313 are simultaneously inserted from the first end of the fixing block 1411 and pass through the through hole, so that the mounting rods 1313 protrude from the second end of the fixing block 1411. The support frame 1412 is located at the second end of the fixing block 1411 to limit the mounting rods 1313 that pass through the fixing block 1411.

[0041] See Figure 7 The support frame 1412 encloses the vertically connected fixed rod 1412A and the track 1412B. The fixed rod 1412A is vertically disposed at both ends of the track 1412B, so that one end of the fixed rod 1412A is vertically connected to the fixed block 1411 and the other end is connected to the track 1412B, so that the track 1412B can pass through the through hole port on the fixed block 1411. The mounting rod 1313 is disposed on the track 1412B and can move along the track 1412B, thereby limiting the mounting rod 1313 on the fixed component 141.

[0042] Furthermore, the track 1412B is a square rod, and the top and bottom of the track 1412B are provided with third slots. One end of the rod body of the mounting rod 1313 is connected to the adjusting rod 1312, and the other end is provided with a limiting component. The limiting component engages with the third slot to allow the mounting rod 1313 to move along the track 1412B.

[0043] Further, see Figure 8 The limiting component includes a bent rod 1314, a ball bearing 1315, and a rotating shaft 1316. The bent rod 1314 is connected to the mounting rod 1313. The rotating shaft 1316 is located in the slot of the bent rod 1314. The ball bearing 1315 is sleeved on the rotating shaft 1316 and can rotate around the rotating shaft 1316.

[0044] The bent rod 1314 includes a first support rod 1314A and a second support rod 1314B that are vertically connected. The first support rod 1314A is connected to the mounting rod 1313, so that the second support rod 1314B is parallel to the mounting rod 1313, thereby forming a square groove between the bent rod 1314 and the mounting rod 1313. Two symmetrically distributed limiting components are provided on the same mounting rod 1313. The grooves formed by the bent rod 1314 and the mounting rod 1313 are opposite to each other to form a square frame, so that the two second support rods 1314B are opposite to each other and do not contact each other.

[0045] The first end of the second support rod 1314B is connected to the first support rod 1314A, and the second end is provided with a fourth slot. The rotating shaft 1316 is located in the fourth slot and the two ends of the rotating shaft 1316 are respectively connected to the two side walls of the fourth slot. The ball bearing 1315 is provided with a through hole, so that the ball bearing 1315 is sleeved on the rotating shaft 1316 through the through hole, thereby the ball bearing 1315 can rotate around the rotating shaft 1316.

[0046] Furthermore, the ball 1315 is used to contact the third slot on the track 1412B and roll within the third slot. Therefore, the ball 1315 protrudes from the fourth slot. The third slot provides a slide for the ball 1315, preventing the ball 1315 from shifting during rolling and further ensuring that the ball 1315 can roll stably.

[0047] The moving assembly 142 includes a moving block 1421 and an adjusting block 1422. The moving block 1421 is a square block with a square through hole. Two adjusting rods 1312 pass through the through hole on the moving block 1421. The adjusting block 1422 is located inside the moving block 1421 and is symmetrically distributed at both ends of the adjusting rods 1312, so that the adjusting rods 1312 can move in contact with the adjusting block 1422 within the through hole of the moving block 1421. In order to ensure that the adjusting rods 1312 can move in contact with the adjusting block 1422, the end face of the adjusting block 1422 that contacts the adjusting rods 1312 is an inclined surface, and the surface opposite to the inclined surface is a plane. The inclination angle of the inclined surface is equal to the inclination angle of the inclined surface on the adjusting rods 1312. By moving the adjusting block 1422 on the inclined surface of the adjusting rods 1312, the distance between the two adjusting rods 1312 can be adjusted. By changing the distance between the two second telescopic rods 13, the clamping jaws 2 can be controlled to clamp RF connectors of different sizes.

[0048] Furthermore, in order to enable the two adjusting rods 1312 to always press against the adjusting block 1422 to achieve the distance adjustment of the two second telescopic rods 13, multiple third springs need to be set between the two second telescopic rods 13, and the third springs are always in a compressed state. The spring force makes the second telescopic rods 13 always press against the adjusting blocks 1422 at both ends.

[0049] Furthermore, the top of the fixing block 1411 is provided with a slide rail 1413, and the third telescopic rod 143 can move on the slide rail 1413; see also Figure 10 The slide rail 1413 is designed in a U-shape, including a vertically arranged third support rod 1413A and a fourth support rod 1413B. Both the third support rod 1413A and the fourth support rod 1413B are square rods. The third support rod 1413A is mounted on the fixed block 1411. The cross-sectional area of ​​the fourth support rod 1413B is larger than that of the third support rod 1413A, so that the fourth support rod 1413B can protrude from both ends of the third support rod 1413A, thereby forming a U-shape, so that a limiting groove is formed between the slide rail 1413 and the fixed block 1411.

[0050] The first end of the third telescopic rod 143 is mounted on the slide rail 1413 and can move along the slide rail 1413. The second end is fixed to the moving block 1421. The third telescopic rod 143 includes a first base 1431, a second base 1432, a third outer sleeve 1433, a third inner rod 1434, and a second spring 1435. The first base 1431 is located at the first end of the third telescopic rod 143. The bottom end of the first base 1431 has a convex groove to match and engage with the slide rail 1413, thereby limiting the third telescopic rod 143 vertically and allowing the first base 1431 to move along the slide rail 1413 to adjust the maximum distance between the fixed component 141 and the moving component 142. The movable component 142 can move a large distance on the adjusting rod 1312 to reduce the distance between the two mounting rods 1313, so that the two arc-shaped pieces 21 can clamp the smaller RF connector; the second base 1432 is vertically disposed on the top of the movable block 1421, one end of the third outer tube 1433 is vertically connected to the first base 1431, and the third inner rod 1434 is inserted into the cavity of the third outer tube 1433 from the other end. The third inner rod 1434 is vertically connected to the second base 1432, so that the movable component 142 can be moved along the adjusting rod 1312 by the change in the length of the third telescopic rod 143, thereby changing the distance between the movable component 142 and the fixed block 1411.

[0051] To adjust the position of the third outer sleeve 1433 on the slide rail 1413, a third adjustment component 1436 is also provided on the third telescopic rod 143. The third adjustment component 1436 includes a fixed plate 1436A and a lead screw 1436B. The fixed plate 1436A is vertically mounted on the fixed block 1411. The fixed plate 1436A has a threaded hole that passes through the plate so that the lead screw 1436B passes through the threaded hole and is rotatably connected to the first base 1431. Tightening the lead screw 1436B can cause it to move the third outer sleeve 1433. Stopping the tightening of the lead screw 1436B can limit the third outer sleeve 1433 to be positioned on the slide rail 1413.

[0052] In order to achieve the telescopic adjustment of the third telescopic rod 143, the third outer sleeve 1433 is also provided with a threaded hole that penetrates the tube wall to install the third adjusting screw 1437. Tightening the third adjusting screw 1437 can press and fix the third inner rod 1434 inside the tube.

[0053] To enable the third inner rod 1434 to automatically extend out of the third outer tube 1433 and improve the convenience of the device, the third telescopic rod 143 is provided with a second spring 1435 and an adjusting tube 1438 connected to the second spring 1435. The second spring 1435 and the adjusting tube 1438 are both sleeved on the third inner rod 1434. One end of the second spring 1435 is connected to the third outer tube 1433, and the other end is connected to the adjusting tube 1438. The second spring 1435 can spring the adjusting tube 1438 away from the third outer tube 1433, so that the adjusting tube 1438 drives the third inner rod 1434 to automatically extend out of the third outer tube 1433.

[0054] Further, see Figure 9 The regulating tube 1438 includes an inner tube 1438A and an outer tube 1438B. The second spring 1435 is connected to the inner tube 1438A. (See attached image) Figure 11 The outer tube 1438B has a stepped cavity inside to connect the inner tube 1438A and the third inner rod 1434. The stepped cavity includes a first cavity and a second cavity, and the first cavity communicates with the second cavity. The first cavity is adjacent to the third outer tube 1433. The inner tube 1438A is located in the first cavity, and a bearing is provided between the outer tube 1438B and the inner tube 1438A, allowing the inner tube 1438A to rotate relative to the outer tube 1438B. The third inner rod 1434... The inner tube 1438A has an external thread and a through hole, while the inner wall of the second cavity has an internal thread. This allows the third inner rod 1434 to pass through the through hole in the inner tube 1438A and be threadedly connected to the outer tube 1438B in the second cavity. Twisting the outer tube 1438B allows the adjusting tube 1438 to move along the third inner rod 1434, thereby adjusting the extension and retraction state of the second spring 1435 and thus adjusting the elastic force of the second spring 1435, which in turn adjusts the elastic force on the moving component 142.

[0055] For ease of operation, the clamp body 1 also includes a control component 4, including a bracket 41, a first finger ring 42 and a second finger ring 43, a support column 44 and a second handle 45. The bracket 41 is a square frame with an open bottom and is located on the top of the fixing block 1411, so that the bracket 41 covers the third outer tube 1433. The top of the bracket 41 is provided with the first finger ring 42. One end of the support column 44 is connected to the second base 1432 and the other end is connected to the second finger ring 43, so that the second finger ring 43 is located on the upper side of the third inner rod 1434. The second finger ring 43 is a square frame, and the square frame is divided into a first part and a second part by the support column 44. The second handle 45 is located on the side wall of the fixing tube, and the plane where the second handle 45 is located is perpendicular to the plane where the first finger ring 42 and the second finger ring 43 are located, for rotating the clamp body 1 to tighten the RF connector clamped by the jaws 2.

[0056] During use, the operator hooks the first ring 42 with their thumb, and hooks the first and second parts of the second ring 43 with their index and middle fingers respectively. By operating the first ring 42 and the second ring 43, the moving component 142 can be moved toward the fixed component 141. At this time, the moving component 142 moves along the inclined surface on the mounting rod 1313. During the movement, the adjusting block 1422 presses against the mounting rod 1313, increasing the distance between the two second telescopic rods 13, thereby increasing the distance between the two arc-shaped pieces 21 and releasing the clamping and fixing of the jaws 2 on the RF connector. Releasing the second ring 43 allows the moving component 142 to move away from the fixed component 141 under the action of the second spring 1435. During the movement, the adjusting block 1422 presses against the mounting rod 1313, decreasing the distance between the two second telescopic rods 13, thereby decreasing the distance between the two arc-shaped pieces 21 and increasing the clamping force of the jaws 2 on the RF connector to achieve clamping and fixing. The fixing block 1411 is then turned by the second handle 45 to tighten the RF connector.

[0057] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in the present invention should be included within the scope of protection of the present invention.
