Description

Technical Field

[0001] This utility model relates to the field of clamping structure technology, specifically to a pickup. Background Technology

[0002] Currently, most pickups on the market have a handle, a tube, and grippers. A pull wire runs through the tube to connect to the grippers, and the other end of the pull wire can be fixed. By pressing a button on the handle, the button moves radially from the tube and presses down on the pull wire, deforming it and pulling the lever on the gripper, causing the gripper to perform a clamping action. This structural design makes the pull wire prone to wear and breakage during long-term use, so there is an urgent need to design a new type of pickup to solve the above problems.

[0034] This application discloses a pickup, including a handle 100, a tube 200, and a clamping device 300 connected in sequence. A pull wire 210 passes through the tube 200 and is connected to the clamping device 300 so that the clamping device 300 can perform a clamping action by moving the pull wire 210. The handle 100 has an inner cavity 110, in which a rotatable first roller 400 is movably disposed. The outer periphery of the first roller 400 abuts against the pull wire 210. A movable switch 500 is provided on the handle 100. The inner end of the movable switch 500 extends into the inner cavity 110 and is connected to the first roller 400. The movable switch 500 is adapted to drive the first roller 400 to push the pull wire 210 so that the clamping device 300 performs a clamping action.

[0035] In this embodiment, the handle 100 is typically used for gripping, the tube 200 provides a suitable extension length, and the clamping device 300 is used for clamping a specified item. A pull cable 210 passes through the tube 200 and is connected to the clamping device 300 to facilitate clamping by moving the pull cable 210. Based on this, the handle 100 has an inner cavity 110, in which a rotatable first roller 400 is movably disposed. The outer periphery of the first roller 400 abuts against the pull cable 210, resulting in rolling contact between the pull cable 210 and the first roller 400. The handle 100 is provided with a movable switch 500, the inner end of which extends into the inner cavity 110 and is connected to the first roller 400. During use... Force is applied to the movable switch 500, causing it to push the pull cable 210 through the first roller 400, thereby driving the clamping device 300 to complete the clamping action. During this process, the contact between the movable switch 500 and the pull cable 210 is changed from conventional sliding friction to rolling friction, which greatly reduces the frictional resistance when the pull cable 210 is pushed, effectively reducing the possibility of breakage of the pull cable 210 and improving the service life of this application. At the same time, since the outer side of the first roller 400 abuts against the pull cable 210, the pull cable 210 can be adjusted to a better tension state, reducing the ineffective stroke of the movable switch 500 when pushing the pull cable 210 through the first roller 400, thereby making the structure of this application embodiment more compact.

[0036] In an optional or preferred embodiment, an annular groove 410 is formed on the outer periphery of the first roller 400, and the pull wire 210 passes through the annular groove 410; the annular groove 410 can limit the pull wire 210 and prevent the pull wire 210 from deviating when it is pulled.

[0037] In an optional or preferred embodiment, the first roller 400 is rotatably connected to the movable switch 500, making the process of the movable switch 500 driving the pull wire 210 through the first roller 400 more stable and reliable.

[0038] In an optional or preferred embodiment, the active switch 500 is configured as a button that can move radially along the tube 200, with the outer end of the button protruding outside the handle 100; the inner end of the button is rotatably connected to the first roller 400.

[0039] In an optional or preferred embodiment, the active switch 500 is configured as a trigger rotatably connected to the handle 100. The trigger includes a lever 510 and a follower lever 520 that are connected to each other and arranged at an angle. A first roller 400 is rotatably connected to the follower lever 520.

[0040] In this embodiment, by configuring the movable switch 500 as a trigger rotatably connected to the handle 100, it is convenient for the user to apply force to the movable switch 500, which conforms to ergonomic design. During use, by moving the lever 510, the driven lever 520 and the first roller 400 rotatably connected thereto rotate, thereby moving against the push-pull line 210 via the first roller 400. For example, refer to the attached... Figure 3 As shown, when the lever 510 is actuated, the driven lever 520 rotates radially outward from the handle 100, thereby causing the pull wire 210 to be displaced both radially and axially, so as to drive the clamping device 300 to clamp.

[0041] In an optional or preferred embodiment, a through hole 120 is provided on the handle 100 corresponding to the driven rod 520 to allow it to enter and exit the inner cavity 110.

[0042] In an optional or preferred embodiment, a mounting hole 521 is provided on the driven rod 520, and a first roller 400 is rotatably connected in the mounting hole 521. A pull wire 210 passes through the mounting hole 521 and abuts against the lower side of the first roller 400.

[0043] In this embodiment, the first roller 400 is disposed in the mounting hole 521, which can reduce the space occupied by the first roller 400 and improve the compactness of the structure; at the same time, the pull wire 210 passes through the mounting hole 521 and abuts against the lower side of the first roller 400, which can make the pull wire 210 tight and easy to push.

[0044] In an optional or preferred embodiment, a second roller 610 is rotatably disposed in the inner cavity 110. The second roller 610 is disposed on the first side of the first roller 400 along the extension direction of the pipe fitting 200, and the pull wire 210 is respectively passed through the upper and lower opposite sides of the second roller 610 and the first roller 400.

[0045] In this embodiment, the second roller 610 can tension the first end of the pull wire 210 on the first side of the first roller 400 while reducing possible wear on the pull wire 210.

[0046] In an optional or preferred embodiment, a third roller 620 is rotatably disposed in the inner cavity 110. The third roller 620 is located on the second side of the first roller 400 along the extension direction of the pipe fitting 200, and the pull wire 210 is respectively passed through the upper and lower opposite sides of the third roller 620 and the first roller 400.

[0047] In this embodiment, the third roller 620 is disposed on the second side of the first roller 400, which can tension the second end of the pull cable 210 while reducing the possible wear of the pull cable 210. In particular, when the second end corresponds to the clamping device 300, since it is often necessary to apply force to the clamping device 300 through the pull cable 210, the setting of this third roller 620 can greatly improve the service life.

[0048] It is understood that by setting the second roller 620 and / or the third roller 630, the pulling process of the pull cable 410 is smooth and not easily worn. At the same time, the pull cable 410 can be tensioned well, which makes it easier for the movable switch 500 to drive the pull cable 410, reducing the ineffective working stroke, thereby making the overall structure of this application more compact.

[0049] In an optional or preferred embodiment, the handle 100 includes a handle tube 130 connected to the tube 200, and a grip handle 140 angled to the handle tube 130; the grip handle 140 extends radially from the tube 200; a lever 510 is disposed on the side of the grip handle 140 facing the clamping device 300; a driven rod 520 is disposed on the side of the tube 200 with its axis facing the lever 510; this structural design can be referred to the appendix. Figure 3 As shown, its pistol-like structural design makes it easy for users to hold and allows for smooth clamping movements.

[0050] In an optional or preferred embodiment, the clamping device 300 includes a clamp base 310, a pull rod assembly 320, and two finger clamping assemblies 330. The clamp base 310 has a tubular end and is connected to the pipe fitting 200. The pull rod assembly 320 is disposed within the clamp base 310, and its first end is connected to a pull cable 210. The second end of the pull rod assembly 320 is connected to the two finger clamping assemblies 330. The pull rod assembly 320 moves along the pipe fitting 200 to drive the two finger clamping assemblies 330 to close together for clamping or to open away from each other. For example, when the pull cable 210 drives the pull rod assembly 320 to move towards the handle 100, the two finger clamping assemblies 330 close together. When the pull cable 210 resets, the two finger clamping assemblies 330 open away from each other. The reset effect can be provided by a reset spring, for example, by connecting the pull rod assembly 320 and the clamp base 310 through a reset spring. The specific finger clamping assembly 330 is prior art and will not be described in detail here.

[0051] In an optional or preferred embodiment, a winding reel 700 is rotatably mounted inside the handle 100 via a torsion spring. One end of the pull cable 210 is connected to the winding reel 700 and wound around its outer side. The tube 200 includes multiple interconnected connecting tubes 220 that can extend and retract axially. A locking structure 800 is provided on the handle 100 corresponding to the winding reel 700. The locking structure 800 can lock or unlock the rotation tendency of the winding reel 700.

[0052] In this embodiment, the overall length of the present application embodiment can be adjusted by the axially movable configuration of the winding reel 700 and the multi-section connecting tube 220. As for the specific adjustment method, for example, a lockable structure can be provided between two adjacent sections of the connecting tube 220, and the locking or unlocking between the two adjacent sections of the connecting tube 220 can be controlled by the lockable structure; or the two adjacent sections of the connecting tube 220 can be fixed by friction. Meanwhile, a locking structure 800 is provided on the handle 100 corresponding to the winding reel 700. The locking structure 800 can lock or unlock the rotation tendency of the winding reel 700. The locking structure 800 is provided here so that when clamping is required in this embodiment, the winding reel 700 can be locked by the locking structure 800. At the same time, since this end of the pull wire 210 corresponding to the winding reel 700 is fixed, the movement of the movable switch 500 will only drive the pull wire 210 at this end of the clamping device 300 to move, so as to achieve effective clamping. When the movable switch 500 is not required to work, the locking structure 800 is in the unlocked state of the winding reel 700, so that the length of the tube 200 can be adjusted.

[0053] Preferably, the locking structure 800 can be controlled by the movement of the movable switch 500, i.e., the two are linked together; for example, a control element 530 is connected to the movable switch 500, and the movement of the control element 530 can control the locking structure 800 to lock or unlock the rotation trend of the winding reel 700; when the movable switch 500 is not needed, the locking structure 800 is in the state of not locking the winding reel 700; at this time, the length of the tube 200 can be adjusted; while the movable switch 500 pushes the pull cable 210, the control element 530 on the movable switch 500 first drives the locking structure 800 to lock the winding reel 700, and then the movable switch 500 continues to move to push the pull cable.

[0054] Specifically, the locking structure 800 includes a toothed disc 810 connected to the reel 700 and a stop 820 movably disposed within the handle 100. The stop 820 has at least two states of use: first, it is inserted between the teeth of the toothed disc 810 to lock the toothed disc 810 and prevent it from rotating; second, it is disengaged from between the teeth of the toothed disc 810, releasing the lock on the toothed disc 810 and allowing the toothed disc 810 and the reel 700 to rotate normally. Preferably, the movement of the stop 820 is controlled by a control element 530 on the movable switch element 500, as shown in the attached diagram. Figure 3As shown, for example, when the active switch 500 is a trigger, one end of the driven lever 520 is rotatably connected to the first roller 400, and the other end of the driven lever 520 is provided with a control member 530 to abut against the stop member 820. When the trigger is not in use, the control member 530 abuts against the stop member 820 and disengages it from the teeth of the gear disc 810. The stop member 820 is connected to the inside of the handle body 100 by a torsion spring, which is in a compressed state at this time. When the trigger is pulled, the control member 530 on the driven lever 520 no longer abuts against the stop member 820. At this time, the torsion spring drives the stop member 820 to reset and insert into the teeth of the gear disc 810 to lock the coil spool 700. As for maintaining the unlocked state of the stop member 820, that is, the force of the torsion spring being compressed, it can be achieved by the return spring in the clamping device 300 and / or by adding a return spring on the trigger rotation shaft.
